To embark on its next chapter in human space exploration, NASA has created a new department to oversee manned spaceflight in the post-space-shuttle era.

The department is called the Human Exploration and Operations Mission Directorate, and combines two previous organizations, the Space Operations Directorate and the Exploration Systems Mission Directorate.

The reorganization is part of top-to-bottom changes moving through the space agency, which finds itself at a turning point. This year NASA retired its 30-year-old space shuttle program, which was the focus and most visible part of its activities over the last few decades. The agency is now gearing up for an era of human missions to deep space, including trips back to the moon, then on to asteroids and Mars.

President Obama has charged NASA to put astronauts on a space rock by 2025, and on the Red Planet by the mid 2030s. To reach those goals, the United States must develop a new heavy-lift rocket capable of traveling that far, and a capsule to bring people safely there and back again.

The new Human Exploration and Operations Mission Directorate will be responsible for overseeing all this and more.

"America is opening a bold new chapter in human space exploration," NASA Administrator Charles Bolden said in a statement. "By combining the resources of Space Operations and Exploration Systems, and creating the Human Exploration and Operations Mission Directorate, we are recommitting ourselves to American leadership in space for years to come."

While NASA is targeting human missions farther out into the solar system than ever before, it hopes to pass on the torch of low-Earth orbit travel to the private space industry. The new office will oversee NASA's Commercial Crew Development program, which aims to stimulate the development of private spacecraft to carry people to orbit, as well as the Commercial Orbital Transportation Services program, which does the same for cargo.

Meanwhile, NASA will continue operating the International Space Station. Until private spaceships are ready, U.S. astronauts will rent rides to the station aboard Russian rockets. The orbiting laboratory is planned to run through at least 2020. This, too, will be supervised from the Human Exploration and Operations Mission Directorate.

Bubbles in our outskirts?!

NASA's Voyager probes are truly going where no one has gone before. Gliding silently toward the stars, 9 billion miles from Earth, they are beaming back news from the most distant, unexplored reaches of the solar system.

Mission scientists say the probes have just sent back some very big news indeed.

It's bubbly out there.

According to computer models, the bubbles are large, about 100 million miles wide, so it would take the speedy probes weeks to cross just one of them. Voyager 1 entered the "foam-zone" around 2007, and Voyager 2 followed about a year later. At first researchers didn't understand what the Voyagers were sensing--but now they have a good idea.

"The sun's magnetic field extends all the way to the edge of the solar system," explains Opher. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are now, the folds of the skirt bunch up."

When a magnetic field gets severely folded like this, interesting things can happen. Lines of magnetic force criss-cross, and "reconnect". (Magnetic reconnection is the same energetic process underlying solar flares.) The crowded folds of the skirt reorganize themselves, sometimes explosively, into foamy magnetic bubbles.

"We never expected to find such a foam at the edge of the solar system, but there it is!" says Opher's colleague, University of Maryland physicist Jim Drake.

Theories dating back to the 1950s had predicted a very different scenario: The distant magnetic field of the sun was supposed to curve around in relatively graceful arcs, eventually folding back to rejoin the sun. The actual bubbles appear to be self-contained and substantially disconnected from the broader solar magnetic field.

Energetic particle sensor readings suggest that the Voyagers are occasionally dipping in and out of the foam—so there might be regions where the old ideas still hold. But there is no question that old models alone cannot explain what the Voyagers have found.

Says Drake: "We are still trying to wrap our minds around the implications of these findings."

The structure of the sun's distant magnetic field—foam vs. no-foam—is of acute scientific importance because it defines how we interact with the rest of the galaxy. Researchers call the region where the Voyagers are now "the heliosheath." It is essentially the border crossing between the Solar System and the rest of the Milky Way. Lots of things try to get across—interstellar clouds, knots of galactic magnetism, cosmic rays and so on. Will these intruders encounter a riot of bubbly magnetism (the new view) or graceful lines of magnetic force leading back to the sun (the old view)?

The case of cosmic rays is illustrative. Galactic cosmic rays are subatomic particles accelerated to near-light speed by distant black holes and supernova explosions. When these microscopic cannonballs try to enter the solar system, they have to fight through the sun's magnetic field to reach the inner planets.

"The magnetic bubbles appear to be our first line of defense against cosmic rays," points out Opher. "We haven't figured out yet if this is a good thing or not."

On one hand, the bubbles would seem to be a very porous shield, allowing many cosmic rays through the gaps. On the other hand, cosmic rays could get trapped inside the bubbles, which would make the froth a very good shield indeed.

So far, much of the evidence for the bubbles comes from the Voyager energetic particle and flow measurements. Proof can also be obtained from the Voyager magnetic field observations and some of this data is also very suggestive. However, because the magnetic field is so weak, the data takes much longer to analyze with the appropriate care. Thus, unraveling the magnetic signatures of bubbles in the Voyager data is ongoing.

"We'll probably discover which is correct as the Voyagers proceed deeper into the froth and learn more about its organization," says Opher. "This is just the beginning, and I predict more surprises ahead."

NASA | Swift Finds Most Distant Gamma-ray Burst Yet

On April 29, 2009, a five-second-long burst of gamma rays from the constellation Canes Venatici triggered the Burst Alert Telescope on NASA's Swift satellite. As with most gamma-ray bursts, this one -- now designated GRB 090429B -- heralded the death of a star some 30 times the sun's mass and the likely birth of a new black hole.
"What's important about this event isn't so much the 'what' but the 'where,'" said Neil Gehrels, lead scientist for Swift at NASA's Goddard Space Flight Center in Greenbelt, Md. "GRB 090429B exploded at the cosmic frontier, among some of the earliest stars to form in our universe."
Because light moves at finite speed, looking farther into the universe means looking back in time. GRB 090429B gives astronomers a glimpse of the universe as it appeared some 520 million years after the universe began.
Now, after two years of painstaking analysis, astronomers studying the afterglow of the explosion say they're confident that the blast was the farthest explosion yet identified -- and at a distance of 13.14 billion light-years, a contender for the most distant object now known.
Swift's discoveries continue to push the cosmic frontier deeper back in time. A gamma-ray burst detected on Sept. 4, 2005, was shown to be lie 12.77 billion light-years away. Until the new study dethroned it, GRB 090423, which was detected just six days before the current record-holder, reigned a distance of about 13.04 billion light-years. All of these gamma-ray bursts were among the first 500 detected by Swift.

Radio Telescopes Capture Best-Ever Snapshot Of Black Hole Jets

WASHINGTON -- An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.

"These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany.

The new image shows a region less than 4.2 light-years across -- less than the distance between our sun and the nearest star. Radio-emitting features as small as 15 light-days can be seen, making this the highest-resolution view of galactic jets ever made. The study will appear in the June issue of Astronomy and Astrophysics and is available online.

Mueller and her team targeted Centaurus A (Cen A), a nearby galaxy with a supermassive black hole weighing 55 million times the sun's mass. Also known as NGC 5128, Cen A is located about 12 million light-years away in the constellation Centaurus and is one of the first celestial radio sources identified with a galaxy.

Seen in radio waves, Cen A is one of the biggest and brightest objects in the sky, nearly 20 times the apparent size of a full moon. This is because the visible galaxy lies nestled between a pair of giant radio-emitting lobes, each nearly a million light-years long.

These lobes are filled with matter streaming from particle jets near the galaxy's central black hole. Astronomers estimate that matter near the base of these jets races outward at about one-third the speed of light.

Using an intercontinental array of nine radio telescopes, researchers for the TANAMI (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) project were able to effectively zoom into the galaxy's innermost realm.

"Advanced computer techniques allow us to combine data from the individual telescopes to yield images with the sharpness of a single giant telescope, one nearly as large as Earth itself," said Roopesh Ojha at NASA's Goddard Space Flight Center in Greenbelt, Md.

The enormous energy output of galaxies like Cen A comes from gas falling toward a black hole weighing millions of times the sun's mass. Through processes not fully understood, some of this infalling matter is ejected in opposing jets at a substantial fraction of the speed of light. Detailed views of the jet's structure will help astronomers determine how they form.

The jets strongly interact with surrounding gas, at times possibly changing a galaxy's rate of star formation. Jets play an important but poorly understood role in the formation and evolution of galaxies. NASA's Fermi Gamma-ray Space Telescope has detected much higher-energy radiation from Cen A's central region.

"This radiation is billions of times more energetic than the radio waves we detect, and exactly where it originates remains a mystery," said Matthias Kadler at the University of Wuerzburg in Germany and a collaborator of Ojha. "With TANAMI, we hope to probe the galaxy's innermost depths to find out."

Ojha is funded through a Fermi investigation on multiwavelength studies of Active Galactic Nuclei.

The astronomers credit continuing improvements in the Australian Long Baseline Array (LBA) with TANAMI's enormously increased image quality and resolution. The project augments the LBA with telescopes in South Africa, Chile and Antarctica to explore the brightest galactic jets in the southern sky.

NASA's Fermi Gamma-ray Space Telescope is an astrophysics and particle physics partnership, developed in collaboration with the U.S. Department of Energy, along with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden and the U.S.

The Australia Long Baseline Array is part of the Australia Telescope National Facility, which is funded by the Commonwealth of Australia for operation as a National Facility managed by the Commonwealth Scientific and Industrial Research Organization.

Dark Energy Confirmed Again!

"We all need to look into the dark side of our nature - that's where the energy is, the passion. People are afraid of that because it holds pieces of us we're busy denying." -Sue Grafton

No, not the dark side of our nature, just the dark side of nature! Because if all our Universe were made out of were atoms and photons, we wouldn't get a Universe that looks like ours.

What do I mean? Let's take a look.

(Image credit: MPA Garching and Volker Springel.)

The Universe starts off as a very smooth place, where regions that are denser or less densethan average are only something like 0.003% away from average. To put it in economic terms, if the average salary were $50,000 a year, the richest person would make about $3 extra, and the poorest person would make about $3 less than average.

But that's the early Universe. Over time, those richer, denser regions attract more and more matter, growing in size and scope.

(Animation credit: Center for Cosmological Physics, National Center for Supercomputer Applications, and Andrey Kravtsov (U. Chicago) and Anatoly Klypin (NMSU).)


Today, we see the very densest regions as being the places with the greatest concentrations of galaxies, and the least dense regions are devoid of almost all matter.

We can even still find galaxies merging today; evidence of the legacy of these small gravitational inequalities from when the Universe was billions of years younger than it is

(Image credit: NASA and The Hubble Heritage Team (STScI).)

But it isn't like we just get giant clumps of galaxies that fall in to one another, and collapse under gravity. As much as we like to pretend that gravity is the only thing that matters in the Universe, there's another force that's often just as important.

Don't believe me? Then think about the biggest, brightest, close object to you in the Universe. 300,000 times as massive as the planet Earth, the Sun's gravity is absolutely tremendous.

(Image credit: NASA/CXC/M.Weiss.)

And yet the Sun is less dense than the Earth is! That's because there's something holding the Sun up that the Earth doesn't have: radiation pressure!

All the nuclear fusion happening at the core of the Sun produces a gargantuan amount of energetic photons. It's so powerful that, at the Sun's surface, the outward pressure is enough to counteract the force of the Sun's gravity, and that's why the Sun doesn't contract or collapse.

And then we come to the Universe.

(Image credit: CCA Zurich.)

Sure, today, the Universe looks a lot like this. The pressure from radiation is totally negligible except in the hottest and densest of objects, like stars.

But go back in time, to when the Universe was very young, and radiation was of incredibleimportance! In fact, for the first 10,000 years of the Universe or so, it was even more important than matter! Which means, during this time, if you were matter trying to collapse under the influence of gravity, radiation pressure would bounce you back out!

(Wish I could find the image credit for this one!)

This is part of why the early Universe is so smooth, for certain. But this feature -- matter trying to collapse under the influence of gravity vs. radiation pressure pushing it back out -- creates a "wave" or "ripple" like you see above. You can see a dense region at the center, you can see it get sparser and sparser as you move away, and then it gets denser once again.

This feature, created by normal atoms (baryons) and radiation (photons), is known as anacoustic oscillation. Why? Because it's a pressure wave, just like sound is! The only difference is, this type of wave determines how galaxies group together.

(Image credit: Chuck Bennett and Nature.)

So if we go and measure how far apart the galaxies in the Universe are spaced from one another, we can figure out:

What percentage of the matter is normal matter,
What percent is dark (non-baryonic) matter, and
How quickly the Universe has expanded since, or what percent of the Universe is dark energy

It's a very clever way to do it, and it's a brilliant way to check our laws of gravity. If we're doing it correctly, and General Relativity is right, we should, by measuring these galaxies, see how the Universe has expanded from the Cosmic Microwave Background over billions of years to form galaxies, and then from those galaxies to our eyes.

(Image credit: NASA's WMAP and the Sloan Digital Sky Survey.)

Well, the WiggleZ team from Australia just released their results this week: the most comprehensive survey -- of 200,000+ galaxies -- designed to measure dark energy by this method.

Their results are a spectacular confirmation of the best prediction of our Universe: one where 70-75% of the energy is dark energy, and where the total amount of baryons is only about 4-5%, with the rest being dark matter. They also found, to the best of their measurements, that dark energy is, in fact, a cosmological constant, with no change over time and the correct equation of state. (I.e., it gives the right pressure/energy density combination to be a cosmological constant.)

Led by Warrick Couch and Michael Drinkwater, and also with scientists such as Chris Blake and Karl Glazebrook, the WiggleZ dark energy survey has been a smashing success, and I'm happy to report that the team appears to have done everything impeccably. Some good press coverage is available here and here, as well as the full press release here.)

The full WiggleZ team (as best as I can find) is pictured below.

And I'd like to say, on a personal note, I'm really impressed, and I'm really happy for all of this!

Most of you don't know this, but before I turned the bulk of my energies towards communicating and teaching science, I was offered a job at Swinburne, working with the WiggleZ team. (Check it out on the old job rumor page.) They were a great group, and they made the job decision an extremely difficult one for me, because I could tell they were doing exciting, top-notch science, and it's great to see it come to fruition like this, even if I wasn't a part of it. Every once in a while, I let my imagination wander to the life I would have had if I had taken it, and all I know is that it would be vastly different than the one I'm living now.

But who knew, more than four years ago when I made that decision, that I'd be telling thousands of you about their smashing success?!

This is another great success for dark matter, dark energy, and the standard big bang picture of the Universe, and yet another tremendous challenge for alternative theories to explain. All you have to do is measure how far apart galaxy pairs are, how that distance changes as the Universe expands, and that's one new way for you to measure dark energy,completely independently of supernovae!

Congratulations to the entire WiggleZ team, and to all of you for learning about the latest, greatest confirmation of the most mysterious force in the Universe!

NASA Clears Endeavour for Next-to-Last Shuttle Flight

At NASA's Kennedy Space Center in Florida, space shuttle Endeavour awaits its final liftoff from Launch Pad 39A.

CAPE CANAVERAL, Fla. — NASA officials have given the space shuttle Endeavour a "go" to launch on its final space voyage Monday (May 16).

The shuttle is now scheduled to lift off from here at Kennedy Space Center (KSC)'s Launch Pad 39A at 8:56 a.m. EDT (1256 GMT). [Photos: Shuttle Endeavour's Final Mission]

We had "unanimous consent from the mission management team to press on with the launch countdown," mission management team chair Mike Moses said during a briefing today (May 14). "We should be in really good shape for launch Monday morning."

Weather forecasters predict a 70 percent chance the weather will cooperate for Endeavour's launch on Monday.

"Overall, it's looking promising for launch, with a 30 percent chance of KSC weather prohibiting launch," shuttle weather officer Kathy Winters said. The main concerns at launch time will be winds at the emergency landing site here at KSC, and the chance of a low cloud ceiling, she said.

This will be the shuttle's second launch try after an earlier attempt was foiled by a failed heater that insulates a critical power unit called an Auxiliary Power Unit (APU) on the shuttle.

Engineers replaced a faulty switch box that had sparked the heater problem, along with wiring to and from the box. [The People Behind Endeavour: Engineers Reflect on NASA's Youngest Shuttle]

Mission managers have "really high confidence" the problem is fixed now, Moses said. "In our minds we are good to go and we have no problems expected with this APU heater anymore in this count."

This will be the last mission for shuttle Endeavour, and the next-to-last flight of NASA's 30-year space shuttle program. Endeavour's goal is to deliver a $2 billion antimatter hunting experiment and a haul of spare supplies for the International Space Station.

Endeavour will spend about 16 days in orbit on a mission that includes four ambitious spacewalks to pack away the spare supplies and upgrade the exterior of the station.

Commander Mark Kelly will lead Endeavour's veteran crew of six astronauts. Kelly's wife, Congresswoman Gabrielle Giffords, D-Ariz., is expected to attend the launch in person despite having been shot in the head in January. Giffords is undergoing rehabilitation at a hospital in Houston.

Space-Time Around Black Holes Visualized

For the first time, physicists have visualized what goes on during the collision of two black holes, providing insight into what one researcher calls the "stormy behavior" of space and time during such a merger.

The findings could help researchers interpret gravitational signals from space to reconstruct the cosmic events that created them, said study researcher Kip Thorne, a theoretical physicist at the California Institute of Technology. The study also opens up a new way to understand black holes, gravity and cosmology.

"It's as though we had only seen the surface of the ocean on a calm day," Thorne told LiveScience. "We'd never seen the ocean in a storm, we'd never seen a breaking wave, we'd never seen water spouts … We have never before understood how warped space and time behave in a storm."

Here's how black holes and space-time are linked: The theory of general relativity, proposed by Albert Einstein in 1915, describes how gravity affects very massive, huge things such as black holes and the universe itself. According to this theory, gravity actually warps the fabric of space-time in such a way that massive objects bend the universe (think a Sumo wrestler on a soft mat) so that objects can't help but fall toward them. Even time can be bent by gravity, the theory goes.

Vortex and tendex

In other words, researchers had a good handle on the forces created by a quietly spinning black hole. They were also able to simulate the results of black hole collisions to see what type of gravitational waves the collisions create. "What we were not able to do is go down and look at the merger itself," Thorne said. [See a video of the black hole collisions]

To visualize a black hole merger, the researchers used two concepts, one old and one new: vortex lines and tendex lines. These lines are the equivalent of the lines drawn to represent magnetic fields, said study author Robert Owen, a postdoctoral researcher in astronomy at Cornell University.

Vortex lines represent a twisting force in space-time. If you were to fall into a vortex line, your body would be wrung like a wet dish towel, Owen said. Tendex lines, which are a new concept, represent a stretching or squeezing force. [Visualization of vortex lines]

"Tendex is actually a word that we had to invent because it didn't exist before this," Owen said.

Using supercomputers, the researchers created simulations of the vortex and tendex lines that would be created when black holes merge. The patterns differ depending on how the merger happens, Thorne said. For example, a head-on collision of two black holes ejects doughnut-shaped vortexes from the merger. Two black holes spiraling into each other create a very different arrangement.[ Gallery: Black Holes of the Universe]

"This is where we see vortexes sticking out of the merged black hole that swing around the merged black hole like spiral arms of the galaxy or like water spraying out of a rotating sprinkler head," Thorne said.

In another simulation of spinning black holes orbiting into each other, the vortexes diffused into one another, Thorne said.

Tracing the source

The researchers are working on three follow-up studies to explore the details of the dynamics involved, Owen said. He said the research team expects that tendexes and vortexes will be used to investigate lots of situations where gravitational forces are very strong, including just after the Big Bang that may have created the universe about 13.7 billion years ago.

Whether any valuable insights will come out of the new visualization method has yet to be seen, University of Texas, Brownsville and Southmost Texas College physicist Richard Price told LiveScience. But the method has more potential than any other method he knows of, Price said.

"My initial impression [upon hearing about the research] was, 'Yeah. This could work,'" said Price, who was not involved in the study.

"You can't calculate everything; you've got to know where to look," Price added. "And therefore, you need to have the ability to visualize."

The results may also help researchers understand the findings of the Laser Interferometer Gravitational-Wave Observatory, or LIGO, an instrument that detects gravitational waves from space. Before, researchers knew enough about black hole collisions to figure out what sorts of waves LIGO should be looking for, Thorne said. Now, scientists can start interpreting those waves when they come in.

"We want to be able to look at the shapes of the waves and be able to go back and say what was happening to produce the waves," Thorne said.

SPACE MUSIC: SETI ARTIST IN RESIDENCE AND AN ORBITAL FLAUTIST

We have some cool bits of Space Music to roundup this week. First, we've already covered NASA's first and last artist in residence (AIR), but what aboutSETI?

 

The ET-seeking non-profit just signed on multimedia artist Charles Lindsay for a three year stint as its first AIR, during which he'll grow the program and "encourage cross disciplinary artistic expression in order to explore and illuminate the origin, nature and prevalence of life in the universe."

As you see in the image above, Lindsay's work definitely has a spaced-out look to it. He uses a camera-less, carbon-based emulsion photographic process. His works also creates custom ambient soundscapes to accompany his work -- a process that includes processing samples from NASA's audio archives. Visit his official website to hear some of this.

As shared over at Wired, it was also a good week for live music aboard the International Space Station. In the following video, astronaut Catherine Coleman plays the flute for us in microgravity, continuing a long tradition of live music in orbit. In the past, humans have taken up. everything from synths to didgeridoos. In fact, ten days before Christmas 1965, the astronauts aboard Gemini 6 performed a rendition of the holiday tune "Jingle Bells" using a harmonica and bells. Anyway, here's Coleman (she whips it out around 1:20):

What else is there to listen to this week? Well, Luke Twyman of Neverest Songs recently scored the film "All that Glitters" and you can test drive the tracks right here. I interviewed Twyman in this previous space music post about his excellent SolarBeat space music application. It's good stuff to drift away to.

Nobel Prize Winner Baruch Blumberg Dies of Apparent Heart Attack

A NASA portrait of Dr. Baruch Blumberg in 1999.

Nobel Prize winner Dr. Baruch "Barry" Blumberg, who served as the first director of the NASA Astrobiology Institute at NASA's Ames Research Center, died of an apparent heart attack while attending a conference at Ames on Tuesday, April 5. He was 85.

Blumberg served as the first director of the NASA Astrobiology Institute from 1999 to 2002. He is best known as the winner of the 1976 Nobel Prize in Medicine for identifying the Hepatitis B virus. Blumberg shared the Nobel Prize with D. Carleton Gajdusek for their work on the origins and spread of infectious viral diseases.

Lynn Harper of NASA's Ames Research Center and Dr. Baruch Blumberg attended the International Space Station (ISS) National Laboratory Workshop in October 2007

Blumberg was a featured speaker and participant at the International Lunar Research Park Exploratory Workshop being held in the NASA Ames Conference Center when he was stricken.

"Barry Blumberg was a great biochemist and researcher," said Ames Center Director Pete Worden. "He was a leading light in the scientific community and a great humanitarian. He also was a loyal and supportive friend to NASA, Ames Research Center and the nation's space program." 

Dr. Baruch Blumberg was introduced as the first director of the NASA Astrobiology Institute during a press conference held at NASA's Ames Research Center in May 1999.

A native of New York, N.Y., Blumberg had been a member of the Fox Chase Cancer Center in Philadelphia since 1964 and held the rank of University Professor of Medicine and Anthropology at the University of Pennsylvania since 1977. Since 2005, he had served as president of the American Philosophical Society, the oldest learning society in the United States, dating back to 1743. He had been a member of the society since 1986.

Blumberg first entered the graduate program in mathematics at Columbia University, but soon switched to medicine and enrolled in Columbia's College of Physicians and Surgeons, graduating with his M.D. in 1951. He remained at Columbia Presbyterian Medical Center for the next four years, first as an intern and then as a resident. He began his graduate work at Balliol College, Oxford, where he earned his Ph.D. in 1957.  

"The world has lost a great man," said former NASA Administrator Daniel Goldin, who served as NASA administrator from 1992 to 2001. "Barry saved lives through his research on the Hepatitis B virus. He also inspired a whole generation of people worldwide through his work in building the NASA Astrobiology Institute. On a personal level, he improved my life through his friendship. Our planet is an improved place as a result of Barry's few short days in residence."

NASA Braces for Possible Government Shutdown

The U.S. Capitol

NASA is once again bracing for a potential shutdown of the federal government, which could begin this weekend if Republicans and Democrats in Congress can't agree on a budget.

U.S. lawmakers have yet to pass a budget for fiscal year 2011, which began in October. As a result, the government has been operating under a series of stopgap funding measures called continuing resolutions. The latest of these is set to expire at 12:01 a.m. EDT Saturday (April 9).

NASA officials expressed hope that Democrats and Republicans can reach an agreement in time to forestall a government shutdown— but they're not necessarily counting on it.

"Given the realities of the calendar, however, prudent management requires that we plan for an orderly shutdown should Congress be unable to pass a funding bill," NASA chief Charlie Bolden wrote in a recent memo to agency employees that was posted online by the websiteSpaceRef.com today (April 6).

Furloughs could be coming

At this point, Republicans are seeking deeper cuts in federal spending than Democrats are willing to concede. If the two sides can't come together by Friday, the federal government could shut down for the first time since 1995.

Federal activities deemed essential to the nation's safety and economic well-being — such as air-traffic control and food inspection — would continue to receive funding. But many other operations would be suspended, and many federal employees furloughed.

NASA has now begun the process of trying to figure out which of its operations and employees would be affected.

"Our contingency planning for the potential funding lapse includes determining which agency functions are excepted from a furlough," Bolden wrote. "Should it become necessary to implement our contingency plans, you will receive formal notice from your manager no later than Friday, April 8th regarding the designation of your position and furlough status."

"Essential" employees exempt from a furlough would almost certainly include anyone involved with keeping astronauts safe and healthy in space, NASA officials said — not to mention the astronauts themselves.

Keeping astronauts safe

There are two NASA astronauts in space today – Cady Coleman and Ron Garan. They are two of the six spaceflyers making up the International Space Station's Expedition 27 crew.

Coleman and two crewmates are currently living on the station. Garan and two other crewmembers will arrive at the orbiting laboratory tonight. They launched into space Monday aboard a Russian Soyuz spacecraft.

"We will take the steps necessary to ensure the safety of our astronauts on the International Space Station and our other missions," said NASA spokeswoman Katherine Trinidad. "Critical personnel will remain in place."

Engineers and technicians actually operating the various NASA spacecraft flying through the solar system could probably stay on as well, experts have predicted. Researchers analyzing spacecraft data, on the other hand, might have to go home for a spell — along with large numbers of support staff, from cafeteria workers to office managers.

NASA's next space shuttle flight — Endeavour's STS-134 mission to the space station — is slated to launch April 29. The space agency is looking into how a government shutdown might complicate preparations for that flight, the shuttle program's second-to-last before it retires later this year.

"NASA is still assessing the potential impact to orbiter processing and the upcoming STS-134 mission," Trinidad told SPACE.com.

It's happened before

This is not the first time a possible government shutdown has loomed. Just last month, for example, lawmakers avoided a potential shutdown by passing another continuing resolution.

And in November 1995, President Clinton and congressional Republicans — led by then House Speaker Newt Gingrich — couldn't come to an agreement in time. A shutdown ensued right in the middle of the space shuttle Atlantis' STS-74 mission to Russia's Mir space station.

NASA employees considered essential to that mission stayed on. But many other workers were furloughed, including NASA's public affairs office.

The 1995 shutdown dragged on for three weeks. While NASA officials hope lawmakers can avert such an incident this time around, they're firming up employees' resolve just in case.

"Your contributions touch people's lives in so many significant ways, and I want you to know how deeply I appreciate your dedication and your expertise," Bolden wrote in the memo. "We're a determined and resilient team and we'll get through this!"

Russian Spaceship 'Gagarin' Arrives at Space Station

A Russian spaceship bearing the name of history's most famous cosmonaut docked at the International Space Station late Wednesday  (April 6) to deliver three new crewmembers to the orbiting lab.

The Soyuz TMA-21 — nicknamed "Gagarin" after Yuri Gagarin, who became the first person in space on April 12, 1961 — successfully docked with the station's Poisk module at 7:09 p.m. EDT (2309 GMT). The spacecraft had launched from Baikonur Cosmodrome in Kazakhstan on April 4, blasting off from the same pad used for Gagarin's historic flight nearly 50 years ago.

"Contact and capture — docking confirmed," a NASA official announced as the "Gagarin" sidled up to the orbiting lab.   

The "Gagarin" launched into space Monday (April 4 EDT) carrying  two cosmonauts and one NASA astronaut to join three other crewmembers already aboard the station, rounding out the orbiting lab's Expedition 27.

The three spaceflyers — NASA's Ron Garan and Russians Alexander Samokutyaev and Andrey Borisenko — will also stay on as part of the next station mission, Expedition 28.

"It was a great couple of days and we're ready to get to work," Garan said.

Garan and Samokutyaev will be flight engineers on both expeditions. Borisenko will serve as a flight engineer on Expedition 27 and later serve as the commander of Expedition 28. [Vote Now! The Best Spaceships of All Time]

The crew received a flood of congratulatory calls from Russia's Mission Control center near Moscow after docking at the space station. Russian space official and the families of the astronaut and cosmonauts were on hand to wish the crew well.

"We love you," Garan's wife Carmel told her husband and his crewmates after their arrival on the station. "We'll keep the fires burning at home, and we'll welcome you home with open arms at the end of your successful mission."

Marking many milestones

All three spaceflyers — and the "Gagarin" — will stay at the space station until September, when they'll come back down to Earth. They'll therefore be aboard the orbiting lab for a series of big spaceflight anniversaries and milestones.

There's the 50th anniversary of Gagarin's flight and the 30th anniversary of the first space shuttle flight. Both of those events occurred on April 12 - Gagarin's mission in 1961 and the shuttle fleet's first launch 20 years later, in 1981. The three new crewmembers will also be aloft for the 50th anniversary of the first American in space — Alan Shepard's flight of May 5, 1961.

They'll also bid farewell to NASA's space shuttle program from the orbiting lab. The space agency isretiring the workhorse vehicles later this year after three decades of service. The last two shuttle flights — Endeavour's STS-134 mission and Atlantis' STS-135 flight — are slated to launch toward the station in April and June, respectively.

The three crewmembers already aboard the station — cosmonaut Dmitry Kondratyev, NASA astronaut Cady Coleman and European spaceflyer Paolo Nespoli — have been there since December. They're scheduled to return to Earth next month.

Gagarin's historic flight

Yuri Gagarin's 1961 flight was a significant victory for the Soviet Union in its escalating space race with the United States. It opened wounds first inflicted by the Soviets' surprise launch of Sputnik 1 — the world's first artificial satellite — in October 1957. [The Top 10 Soviet and Russian Science Missions]

Gagarin launched in a spherical Vostok 1 capsule, orbited Earth once, then landed safely in a Russian field 108 minutes later.

While Gagarin's name will live forever in the history books, the man himself died tragically young. His plane crashed during a military training exercise in 1968, killing the cosmonaut at the age of 34.
