After 16 years in space, NASA’s Rossi X-ray Timing Explorer (RXTE) has been shut down

5:16 pm

After 16 years in space, NASA’s Rossi X-ray Timing Explorer (RXTE) has finally been shut down.

RXTE far exceeded its original science goals and leaves astronomers with a scientific bounty for years to come. Data from the mission have resulted in more than 2,200 papers in refereed journals, 92 doctoral theses, and more than 1,000 rapid notifications alerting astronomers around the globe to new astronomical activity.

“The spacecraft and its instruments had been showing their age, and in the end RXTE had accomplished everything we put it up there to do, and much more,” said Tod Strohmayer, RXTE project scientist at Goddard. The decision to decommission RXTE followed the recommendations of a 2010 review board tasked to evaluate and rank each of NASA’s operating astrophysics missions.

A NASA inquiry into the ownership of a variety of space artifacts, including Jim Lovell’s Apollo 13 checklist, has halted their sale at auction.

Power grab: A NASA inquiry into the ownership of a variety of space artifacts, including Jim Lovell’s Apollo 13 checklist, has halted their sale at auction.

In other words, it appears that NASA management has decided that everything ever built by NASA belongs to NASA, forever, even if NASA would have thrown it away at some point.

Space exploration and the unexpected consequences of government decisions

4:24 pm

On Thursday, December 15, 2011, NASA management announced what seemed at first glance to be a very boring managerial decision. Future contracts with any aerospace company to launch astronauts to and from the International Space Station (ISS) will follow the same contractual arrangements used by NASA and SpaceX and Orbital Sciences for supplying cargo to the space station.

As boring that sounds, this is probably the most important decision NASA managers have made since the 1960s. Not only will this contractual approach lower the cost and accelerate the speed of developing a new generation of manned spaceships, it will transfer control of space exploration from NASA — an overweight and bloated government agency — to the free and competitive open market.

To me, however, the decision illustrates a number of unexpected consequences, none of which have been noted by anyone in the discussions that followed NASA’s announcement back in mid-December.

Former astronaut John Grunsfeld is to take over NASA’s science post from Ed Weiler

9:43 am

Excellent choice: Former astronaut John Grunsfeld has been picked to take over NASA’s chief science post from Ed Weiler.

Not only is Grunsfeld an excellent choice, his experience as an astronaut repairing Hubble will help improve relations between the science and manned space programs. In the past, scientists have often argued against manned space, trying to get that money for their unmanned research probes. Instead, when manned space got cut, so did science, and no one won. Grunsfeld’s leadership I think will forestall these short-sighted complaints.

Alan Boyle describes the details behind NASA’s decision to go with simpler contracting for future commercial rocket contracts

2:06 pm

Alan Boyle describes the details behind NASA’s decision to go with simpler contracting for future commercial rocket contracts.

If you read the article, you’ll notice that the opposition to this decision comes from a Congressman and the GAO. In both cases they cite safety as an issue, as is by some magic giving NASA a lot of bureaucratic approval rights on every design is going to make the rockets or capsules safer. All this will really do is slow things down, increase costs, and possibly increase risks as the companies will no longer have as many resources to focus on design issues. Instead, they will have to spend a fortune pleasing NASA bureaucrats.

And yes, I call them bureaucrats. Any NASA engineer who spends his or her time looking over the shoulder of another engineer — who is doing the real design work — is nothing more than a bureaucrat. Better to quit NASA and get a job with one of these new companies where you can do some real work.

NASA has decided to stick with the same contracting arrangement it used for the COTS contracts

11:13 am

Good news: NASA has decided to stick with essentially the same contracting arrangement it used for the SpaceX and Orbital Sciences cargo deals to ISS in its future commercial crew and cargo contracts.

This suggests that the NASA bureaucracy, which had wanted more control of the new commercial companies by using a more restrictive contract arrangement, has lost. However, we don’t yet have the details on how the new contracts will be administrated, and as always, the devil is in the details.

An audit by NASA’s inspector general finds that NASA can’t keep track of its moon rocks

3:47 pm

An audit by NASA’s inspector general has found that NASA can’t keep track of its moon rocks.

In a report issued by the agency’s Inspector General on Thursday, NASA concedes that more than 500 pieces of moon rocks, meteorites, comet chunks and other space material were stolen or have been missing since 1970. That includes 218 moon samples that were stolen and later returned and about two dozen moon rocks and chunks of lunar soil that were reported lost last year.

NASA confiscates stolen rocket engine that had been put up for sale on ebay

5:13 pm

NASA has confiscated a stolen rocket engine from a man who put up for sale on ebay.

Rocket engines are supposed to be under particularly tight control at NASA: the US is keen to avoid its rocket technology winding up in the hands of countries with which it has a tense relationship, such as China. “Security at NASA is not adequate in my opinion,” says Joseph Gutheinz, a former investigator for OIG.

You think, eh?

The 1960s space race: The US orbits its first living animal, Enos the chimpanzee

6:01 pm

An evening pause: Fifty years ago today the United States succeeded for the first time in placing a living animal in orbit, four years after the Soviet’s launched the dog Laika into space. On November 29, 1961 NASA orbited a chimpanzee named Enos as a dress rehearsal for John Glenn’s orbital flight, then scheduled for early in 1962. See this article for some details about Enos difficult flight.

Since the flights of Gagarin, Titov, Shepard, and Grissom earlier in 1961, the 1960s space race had seemed in abeyance as NASA geared up for its first orbital manned mission, while the Soviets were typically silent about their plans. Yet, for those like myself who were alive at that time, the suspense never abated. What would happen next? Could the U.S. beat the Russians to the Moon? Only time would tell.

NASA budget compromise

8:27 am

Congress has come up with a NASA budget compromise. More details here.

Overall, the NASA budget is cut by about a half billion dollars, the total matching what the agency got in 2009. The key figures are $406 million for commercial manned space, $3 billion for NASA’s in-house heavy-lift rocket and capsule, and $529 million to finish the Webb telescope.

I predict that the $3 billion will be a waste of money, the project getting cancelled before completion.

NASA, the federal budget, and common sense

12:41 pm

Let’s be blunt: the federal government is broke. With deficits running in the billions per day, there simply is no spare cash for any program, no matter how important or necessary. Nothing is sacrosanct. Even a proposal to cure cancer should be carefully reviewed before it gets federal funding.

Everything has got to be on the table.

Thus, no one should have been surprised when word leaked two weeks ago that the Office of Management and Budget in the Obama administration was proposing cutting the entire unmanned planetary program at NASA, while simultaneously eviscerating the space agency’s astronomy program. No more missions to Mars. No probes to Europa or Titan. Further and longer delays before the James Webb Space Telescope is completed. And Kepler’s mission to find Earth Like planets orbiting other stars would end mid-mission.

The Obama administration has to find ways to trim the budget, and apparently it is considering eliminating these programs as a way to do it.

Yet, the money spent on space astronomy and planetary research is a pinprick. Considering that the federal government overspends its budget by approximately $3.5 billion per day, and the total amount of money spent on these two science programs equals about $2.4 billion per year, it seems senseless at first to focus on these kinds of cuts. Quite clearly, even eliminating them entirely will not put the federal budget into the black.

Now I am not one to say, “Cut the budget, but please leave my favorite programs alone!” I recognize the serious financial state of the nation, and realize that any budget suggestions I make must include significant total cuts to NASA’s budget.

As a space historian and science journalist who knows a great deal about NASA, however, I also know that there is plenty of room for cuts in NASA’s budget. By picking our priorities carefully at a time when our options are limited, NASA might even be able to accomplish more, not less, with a smaller budget.

Moreover, if I, as a space junky, think it is possible to continue NASA’s most important programs and still trim its budget by 15% to 20%, in real dollars, doesn’t that suggest that the same could be done across the entire federal government?

All it takes is a little knowledge, some common sense, and the courage to say no.

NASA halting work on its J-2X rocket engine

6:30 pm

Par for the course: NASA, having successfully completed a 500 second test of the J-2X rocket engine, has halted all further development work on that engine.

The NASA program to build the heavy-lift rocket is expected to get $1.2 billion per year, and yet it doesn’t have enough money to develop both its first and second stages simultaneously? Kind of proves my point that NASA’s fixed labor costs, imposed on it by Congress, makes it impossible for the agency to ever build anything at a competitive price.

The result: every project dies stillborn.

NASA picks the Delta 4 Heavy to launch Orion into orbit on its first test flight

8:03 pm

NASA has chosen the Delta 4 Heavy rocket to launch the Orion capsule into orbit for its first test flight in 2014.

So, tell me again why NASA needs to spend $18 to $62 billion for a new rocket, when it already can hire Lockheed Martin to do the same thing? Though the Delta 4 Heavy can only get about 28 tons into low Earth orbit, and only about 10 tons into geosynchronous orbit — far less than the planned heavy-lift Space Launch System rocket — Boeing Lockheed has a variety of proposed upgrades to Delta 4 Heavy that could bring these numbers way up. Building these upgrades would surely be far cheaper than starting from scratch to build SLS.

Corrected above as per comments below.

NASA moves first flight test of Orion capsule up three years to 2014

12:16 pm

NASA has moved the scheduled first flight test of the Orion capsule up three years to 2014.

This action, while good, was almost certainly triggered by the competition from the private space companies. The managers at NASA are finally realizing that if they don’t speed up deployment of their own spacecraft, they will certainly lose in the competition for government dollars. That they will have to use another rocket other than their heavy-lift vehicle for this launch, however, will not help that particular project’s lobbying effort.

Either way, I think this action is only further proof that the more competition we have, the quicker we will get into space. And the journey will cost less too, not only because it will take less time and therefore less money, but the competition between companies (or NASA) will force everyone — including NASA — to lower costs to show they can do it better.

An inside look at NASA bureaucratic madness

8:36 pm

An inside look at NASA’s bureaucratic madness.

Much of the time NASA appears to be a loose confederation of 10 quasi independent fiefdoms, each pretty much in charge of their own business. People often ask me what would I do if I were king of NASA for a day. They expect me to say something like: build this rocket, launch that satellite. Rather I think how I would standardize the procurement processes, or the human resources procedures, or the engineering standards used across the agency. But then I always was a dreamer, tilting at impossible windmills. Launching rockets is easy; getting engineers to agree on standards is hard.

And people wonder why I strongly oppose NASA’s heavy-lift rocket (which I think will never get built), or worry that NASA’s interference will choke to death the new independent commercial space companies.

A NASA senior review of all planetary missions?

12:37 am

Here’s a tidbit I just spotted on the EPOXI (formerly Deep Impact) status website, buried in a November 1, 2011 update::

Meanwhile, NASA has decided that there will be a senior review of all operating planetary exploration missions. That will likely include a review of the status of the Deep Impact Flyby spacecraft to determine whether an additional extended mission should be approved. Decisions will not occur until early 2012.

Though Deep Impact is still a functioning spacecraft in orbit around the sun, up until this notice I had not heard of any plans to use it again after its flyby of Comet Hartley-2 in 2010. However, there is no reason its cameras could not be used for astronomy, though unfortunately its high resolution camera has a focus problem which prevents it from taking the sharpest images.

However, the timing of this review of planetary missions, combined with the story last week that the Obama administration might end all funding for future planetary missions, is intriguing. I wonder if they are tied together in some way. That the notice above says the decision will be made in “early 2012” — the moment when the Obama administration will unveil its 2012 federal budget recommendations — strongly suggests that they are linked.

Could that the administration be thinking it can salvage the bad press it will receive for shutting down all future planetary missions by spending a small amount on extending missions already in space? Or is this planetary review another indication that the rumors are true and the administration plans to end the planetary science program entirely?

Unfortunately, I am speculating here, without any real information. Stay tuned to find out.

Sailing to Mars

9:15 am

With the end of the Mar500 simulated mission this coming Friday, the Russians are now proposing an eighteen month simulated Mars mission on board the International Space Station.

The Russians have been pushing to do this on ISS for years. Unfortunately, NASA has always resisted.

Yet, as I wrote in Leaving Earth, we will never be able to send humans to any other planets until we have flown at least one simulated mission, in zero gravity in Earth orbit, beforehand. Wernher von Braun pointed out this reality out back in the 1950s, and that reality has not changed in the ensuing half century. Not only will such a mission tell us a great deal about the medical issues of living in weightlessness for years at a time — issues that are far from trivial — it will give us the opportunity to find out the engineering problems of building a vessel capable of keeping humans alive during interplanetary flight, far from Earth.
