Two NASA employees indicted for allowing Chinese scientist access

8:37 am

Two NASA supervisors from the Langley Research Center in Virginia have been indicted for allowing a Chinese scientist unrestricted access to the facilities there for two years, including allowing the scientist to return to China with a NASA-issued laptop.

What I find amazing about this indictment is that a U.S. attorney in the Obama Justice Department has issued it. The Obama administration and NASA administrator Charles Bolden want unrestricted cooperation with China, and have even done some things that could also violate the same laws against providing U.S. technology to China. Under these conditions, I would have thought the attorney would have been ordered to drop the case, just as the Obama administration has done with numerous other examples where someone in that administration did something illegal and got away with it.

R.I.P. George Mueller

8:32 am

One of the most important managers during the 1960s and 1970s at NASA, George Mueller (pronounced “Miller”) has passed away at 97 after a short illness.

NASA and sources close to Mueller’s family confirmed his passing on Thursday (Oct. 15).

Mueller, as associate administrator, headed the Office of Manned Space Flight at NASA’s Washington headquarters from 1963 through 1969. During that time, Mueller brought together NASA’s three human spaceflight centers under a common management system, introduced an approach to testing that made landing a man on the moon by the end of the decade possible, played a key part in the design of the United States’ first space station and advocated for a reusable space transportation system that became known as the space shuttle.

Unlike the many government managers that followed him, Mueller’s goal was never to build an empire, but to get humans into space as quickly and as efficiently as possible. If only we had more people like him.

NASA pulls funding from private asteroid hunter

10:57 pm

Because of a failure to meet its developmental deadlines, NASA has cut its ties with the privately funded Sentinel satellite, designed to spot 90% of all near Earth asteroids that might pose a threat to the Earth.

The problem for the B612 Foundation, the private company committed to building Sentinel, is that they haven’t clearly laid out a way any investors could make money from the satellite. Thus, they have so far raised only $1.6 million from private sources. They need almost half a billion to build it, according to their own budget numbers.

High res radar instrument fails on Earth observation satellite

9:18 am

Only seven months after launch one of the two instruments on NASA’s Soil Moisture Active Passive (SMAP) Earth observation satellite has failed.

Launched on Jan. 31, the Soil Moisture Active Passive spacecraft’s objective is to map global soil moisture and to detect whether soils are frozen or thawed. It is the first mission where scientists have attempted to collect high-resolution, high-accuracy soil moisture data, said Kent Kellogg, SMAP’s JPL-based project manager.

NASA budgeted $916 million for the mission and has been working on it for the past eight years. “We do a lot of testing on the ground to make sure the designs will be built properly and will last in the environment,” Kellogg said. “But space is a very unforgiving place, and we can have these kinds of problems where despite our best efforts with design and vigorous testing, something surprises us. It’s very uncommon, but these things can happen occasionally.”

SMAP’s two scientific tools are an active radar and a passive radiometer. They complement each other, making up for the other’s measurement limitations. The broken radar collected soil moisture and freeze-thaw measurements at a higher resolution of up to 1.9 miles. The still functioning radiometer generates more accurate measurements but its resolution is lower at about 25 miles. [emphasis mine]

I am not satisfied by the explanation for the failure expressed above. NASA spent a lot of money for this science satellite over almost a decade. In addition, we have been launching instruments like this for almost half a century, and have by now learned quite well the engineering necessary to keep them operating under the conditions in low Earth orbit. I suspect a screw-up somewhere, which we might or might not ever identify.

Soyuz capsule maneuvers to avoid space junk

8:53 am

The manned Soyuz capsule bringing three astronauts to ISS was forced to make a maneuver this morning to avoid a collision with a fragment from a Japanese rocket launched in 1989.

While space junk is an increasing problem, for a object to threaten a manned capsule making maneuvers in low Earth orbit is extremely rare. It appears from the story however that U.S. and Russian trackers thought there was a very good chance of an actual collision and took action to avoid it.

Orbital ATK cargo contract extended

4:56 pm

The competition heats up: NASA has ordered two more cargo flights from Orbital ATK.

Orbital ATK, Dulles, Virginia, will fly two more missions under its 2008 contract for a total of 10 flights, according to Orbital ATK spokeswoman Vicki Cox. The company designated the missions OA-9e and OA-10e, Cox said. She declined to say when those flights will occur, although the company has said it plans to launch any new CRS missions it gets from NASA on Antares once it completes two deliveries using United Launch Alliance’s Atlas 5 rocket. The Atlas 5 launches are slated for December and early 2016 from Cape Canaveral, Florida.

NASA may also order additional cargo flights from its other CRS contractor, SpaceX of Hawthorne, California. “A modification is in work with both [CRS] providers,” NASA spokeswoman Stephanie Schierholz wrote in an Aug. 13 email. “Additional missions for SpaceX are still under discussion.”

That this contract extension occurs about the same time NASA decided to delay its decision on the second round of cargo contracts is probably not a coincidence. It suggests to me that the agency is probably seriously considering awarding one of the next contracts to a more risky proposal, such as Sierra Nevada’s Dream Chaser. In that case, extending the present contracts gives them some additional margin should the new contractors have problems.

NASA postpones decision again for 2nd ISS cargo contracts

8:44 am

In the heat of competition: NASA has again delayed its decision on awarding its second round of contracts for providing cargo to ISS, delaying the decision from September until November 5.

The launch failures this year is the major reason NASA has held off making a decision. They need to see how both SpaceX and Orbital ATK react to the failures, as both have also bid for second round contracts.

NASA considers using Bigelow module for deep space missions

8:56 am

The competition heats up: Rather than build something in-house for gobs of money and decades of work, NASA is considering using Bigelow Aerospace’s largest inflatable modules for its deep space missions.

What has happened is that NASA has signed a joint agreement with Bigelow to study the possibility of using Bigelow’s B330 module as a transport habitat on long flights. The agency really has no choice, as it doesn’t have the funding to develop the necessary large spacecraft for these missions, and Bigelow can provide them to it for much less.

This description of the background of Bigelow’s inflatable modules illustrates why NASA can’t build these itself:

The B330 evolved from the Genesis I and II modules that Bigelow Aerospace had launched into space. Those technology demonstrators were born out of the NASA project known as TransHab. The TransHab was an inflatable module designed for the ISS but was ultimately cancelled in 1999 due to budget constraints. The module would have provided a 4 level 27.5 feet (8.4 meter) diameter habitat for the astronauts.

After TransHab was cancelled, Bigelow worked with NASA on a technology transfer, giving Bigelow Aerospace exclusive rights to the technology. Using this technology, Bigelow designed, built and launched two technology demonstrators. They are still on orbit today. Genesis I was launched in 2006 with it’s sister ship launching in 2007. Both ships tested flight operations processes and on-board electronics and have performed above design specifications. [emphasis mine]

Unlike NASA, as a private company Bigelow was able to build this technology quickly and at a low cost. With the new agreement, the goal will be study the operation of a B330 in independent flight in low Earth orbit. Whether an actual B330 will be build and launched however is not yet clear.

Ten years after the Russians did it, NASA finally produces lettuce in space

9:29 am

Lots of news stories today about yesterday’s lettuce feast on ISS, where a Japanese and two NASA astronauts chowed down on lettuce grown in a NASA-built space greenhouse, ten years after the Russians did it with the American-built and still working LADA greenhouse.

Almost all the stories below, however, fail to note that earlier effort, and instead make the false claim that this NASA experiment is the first to grow lettuce in space.

Only the last article, written at an alternative space news website normally focused on the collection of space memorabilia, gets it right, noting that the Russians did it more than a decade ago and have since then been regularly growing lettuce, peas, and radishes on ISS — and eating them. (They also link to the 2003 Air & Space article I wrote on this very subject.)

Meanwhile, take a scan of all the important mainstream news outlets above, none of whom did the slightest bit of research or fact-checking so they could find out that NASA’s experiment now is not the first, and in fact is more than a decade behind an earlier co-operative effort between the Russians and Utah State University.

This should make you wonder if maybe their other news research is as sloppy.

Update on Boeing’s CST-100

8:55 am

This article provides an update on the status of the construction of Boeing’s CST-100 manned capsule.

It also describes NASA’s lobbying effort with Congress to get the full budget it had proposed for the construction of the commercial crew spacecraft.

I note instead the apparent bureaucratic focus of all the work Boeing seems to be doing.

Following the CBR [Certification Baseline Review], Boeing successfully completed the Ground Segment CDR (Critical Design Review) on 4 December 2014 before moving onto the Phase 2 Safety Review (Part B) in early January 2015. By mid-March, Boeing completed the Phase 2 Safety Review (Safety Technical Review Board Readiness) and moved on to the Delta Integrated CDR, which took place on 27 March 2015.

Since then, Boeing has spent the summer months conducting the Phase 2 Safety review (STRB 80%) as well as producing the CDR for the launch elements of the program and the Qualification Test Article Production Readiness Review.

Moreover, in late July, teams at the Kennedy Space Center began building the Structural Test Article (STA) for the CST-100 capsule inside former Orbiter Processing Facility bay 3 (OPF-3).

Lots of reviews, but notice in the last paragraph they have only begun building the first capsule. As much as these reviews might help them make sure they are doing things right, they seem to create a situation where the company is able to slow-walk construction to help NASA with its congressional lobbying effort, while simultaneously making it sound like they are accomplishing a lot.

NASA extends Russian crew ferry contract through 2019 for $490 million

8:09 pm

Lobbying Congress: Claiming that the unwillingness of Congress to fully fund its effort to build commercial manned space ferries, NASA announced today that it has extended its contract with the Russians through 2019, at a cost of $490 million.

For the next fiscal year, House Republicans have proposed allocating nearly $250 million less than the request, while Senate Republicans would offer $300 million less. If Congress doesn’t increase the allocation, Boeing and SpaceX likely will receive orders to immediately suspend all operations either next spring or summer, Bolden said. And if those orders are issued, Bolden said the existing contracts “may need to be renegotiated, likely resulting in further schedule slippage and increased cost.”

According to this article, the extension has also increased the cost per astronaut flight from $71 to $82 million.

The irony here is that I do not believe Congress’s cuts to this program have slowed SpaceX’s effort down in the slightest. I expect that, barring more flight failures or orders from NASA to stop work, they could fly their first manned Dragon flight by 2017.

Boeing however is probably dragging its feet, since it really isn’t that much interested in achieving manned flight as much as squeezing cash out of Congress. It is probably thus eagerly working with NASA in this lobbying effort.

Meanwhile, the Republican idiots in Congress are claiming — falsely — that these cuts are forced on them by sequestration. This is a lie, as they have, at the same time they have cut commercial crew, increased the budget for SLS. If they were really interested in serving the needs of the nation they would have cut SLS, which can’t accomplish anything and is a terrible waste, and sent the money to commercial crew instead.

But then, who said they were interested in serving the needs of the nation? It doesn’t appear that way to me.

Orion might not be ready for 2018 test flight

8:42 am

Government in action! Last week NASA admitted that the Orion capsule and its service module might not be ready for its 2018 test flight.

Bill Gerstenmaier, head of NASA’s human spaceflight directorate, told members of the [NASA Advisory Council’s human exploration] subcommittee the Orion capsule’s European-made service module, which is being developed by Airbus Defense and Space, will probably be the last piece of the critical test flight to be ready for launch.

NASA and ESA officials, together with contractors from Orion-builder Lockheed Martin and Airbus, have discussed shipping the Orion service module from Europe to NASA’s Kennedy Space Center in Florida before it is finished. European engineers could travel to the Florida spaceport to complete construction of the service module before its integration with the Orion crew capsule, which is to be assembled by Lockheed Martin at KSC’s Armstrong Operations and Checkout Building.

Engineers plan to introduce changes to the Orion crew module after a successful orbital test flight in December 2014. The upgrades include a switch from a monolithic heat shield made of ablative Avcoat material to blocks of Avcoat, a change intended to improve the manufacturability of the thermal protection system. [emphasis mine]

I have highlighted the last paragraph above because it is written to give the false impression that the decision to change the heat shield resulted from the December 2014 test flight. The truth is that NASA had already decided to change heat shields before the test flight. Why NASA engineers are still “planning” to introduce these changes illustrates why government operations are absurdly wasteful.

Orion was first proposed by President George Bush in 2004. The first Orion contract was awarded in 2006. It is now a decade later, and NASA is suddenly warning us that they might not get a single capsule and service module built by 2018, 12 years after construction began. During that time they have spent approximately a billion dollars per year on Orion. For what?

Kennedy proposed going to the Moon in 1961. Eight years later Americans were walking there. Pearl Harbor was attacked on December 7, 1941. The U.S. completed the total defeat of Germany, Italy, and Japan in slightly more than three years, by the spring of 1945.

Today’s NASA however can’t get a single capsule and service module built in 12 years. The contrast is striking. Anyone with the slightest bit of common sense would say that with a track record like this, this program should be shut down now.

NASA considers offering SLS for commercial payloads

9:13 am

Squelching the competition: NASA is pushing to redesign its expensive and giant Space Launch System (SLS) rocket so that it can be used to launch commercial, military, and scientific payloads as well as proposed manned exploration missions.

At the moment, SLS has no planned payloads or funded flights past its second test flight in 2021. The system is very expensive, however, and the only way other customers could afford it would be if NASA charges them far less than the actual cost to fly. In such circumstances, NASA would essentially be subsidizing SLS so that it could compete, even undercut, private commercial rockets that actually cost far less.

If NASA does this, they could very well squelch the emerging private commercial launch industry.

Russians confirm their commitment to ISS through 2024

9:36 am

Even as a new crew arrived at ISS, the head of Roscosmos confirmed that the Russians are now committed to sticking with ISS through 2024, as requested by the U.S.

I’ll make a prediction: The station’s life will be extended beyond 2024, but not necessarily under the control of its present international partnership. If the governments involved consider backing out at that time, there will be private companies then capable of taking it over, and will demand that the U.S. transfer ownership to them. This will in turn act to pressure the governments to continue the station’s operation.

Either way, ISS will continue.

Meanwhile, quality control issues continue to pop up with the Russians. One of the solar panels on the Soyuz capsule that delivered crew to ISS yesterday had failed to open when commanded, then decided to pop open unannounced during the docking. They had enough power to get to the station with only one panel, and the panel opening at the wrong time fortunately did not cause any problems, but for the panel to open as it did is without doubt worrisome.

The Earth from a million miles away

8:54 am

Earth from a million miles away

Cool image time! NASA’s DISCOVR solar observation probe has released its first image of the Earth, taken from its station-keeping position a million miles from Earth.

This camera was originally designed for Al Gore’s proposed propaganda mission where a spacecraft would take daily pictures of the Earth to pound home his environmental agenda. Eventually NASA found a real use for the satellite’s overall structure and location, observing the Sun’s activity and give us advance warning of dangerous flares or coronal mass ejections.

They left the Earth-viewing camera on board, partly because it was built already (it would cost money to remove) and partly because daily images like this can be of some scientific value.

Russia considers building heavy-lift rocket like SLS

10:05 am

The competition heats up: Sources in Roscosmos, Russia’s government agency in charge of their entire aerospace industry, today revealed that the agency is considering building a heavy-lift rocket, as powerful as NASA’s SLS rocket but more similar to Energia, the heavy-lift rocket built by the Soviet Union in the 1980s.

The cost would be $12.2 billion, or 1 trillion rubles, and would take 7-8 years to complete. If approved, the work would also not begin until after 2025 so that the development of Angara’s full family of rockets is completed first.

Meanwhile, a GAO audit today noted that NASA has little margin for completing SLS on time and on budget.

Big, inefficient, and costly rockets: This is what governments do. Their goal? To provide jobs and pork. Even if the rocket never flies it matters not, as long as that pork keeps flowing.

NASA names its astronauts for the first Dragon and CST-100 flights

10:04 am

The competition heats up: NASA today named the four government astronauts that will fly on the first manned demo flights to ISS of SpaceX’s Dragon and Boeing’s CST-100.

Bob Behnken, Eric Boe, Doug Hurley and Sunita Williams are veteran test pilots who have flown on the shuttle and the International Space Station. ….

NASA said the four astronauts will train with both companies and have not yet been assigned to flights. Two-person crews will fly the first test flights by each capsule, after they have completed an orbital test flight without people on board. Company proposals anticipate an all-NASA crew flying SpaceX’s Dragon test flight, with Boeing’s CST-100 carrying a split NASA-Boeing crew. Boeing has not yet identified its astronaut.

NASA to waste $150 million on SLS engine that will be used once.

10:01 am

Government marches on! NASA’s safety panel has noticed that NASA’s SLS program either plans to spend $150 million man-rating a rocket engine it will only use once, or will fly a manned mission without man-rating that engine.

The Block 1 SLS is the “basic model”, sporting a Delta Cryogenic Second Stage (DCSS), renamed the Interim Cryogenic Propulsion System (ICPS) for SLS. The current plan calls for this [interim] stage to be used on [the unmanned] Exploration Mission -1 (EM-1) and [manned] Exploration Mission -2 (EM-2), prior to moving to the [Exploration Upper Stage] – also to be built by Boeing – that will become the workhorse for SLS.

However, using the [interim upper stage] on a crewed mission will require it to be human rated. It is likely NASA will also need to fly the [Exploration Upper Stage] on an unmanned mission to validate the new stage ahead of human missions. This has been presenting NASA with a headache for some time, although it took the recent ASAP meeting to finally confirm those concerns to the public.

Up until now, no one at NASA would admit that their SLS plans called for flying humans with an upper stage that has not been man-rated. They don’t have the funds to man-rate it, and even if they get those funds, man-rating it will likely cause SLS’s schedule to slip even more, something NASA fears because they expect the commercial manned ships to be flying sooner and with increasing capability. The contrast — a delayed and unflown and very expensive SLS vs a flying and inexpensive commercial effort — will not do SLS good politically.

However, if they are going to insist (properly I think) that SpaceX and Boeing man-rate their capsules and rockets, then NASA is going to have to man-rate its SLS systems as well. The result: more problems for SLS, contributing to what I believe will be its inevitable cancellation.

NASA to launch first interplanetary cubesats

9:13 am

The competition heats up: When it launches its next Mars mission, a stationary lander, NASA will piggyback two cubesats, designed to fly past Mars and relay communications during the landing.

As I’ve noted earlier, standardized small cubesats are the future of unmanned satellite operations. Expect them to increasingly replace all types of larger satellites. And because they are small and cheap (both to make and launch), expect them to lead to a burst of new capitalistic activity in space.

Update: In related news, a small private company has delivered to NASA the first thrusters designed for cubesats. Up until now, cubesats have not been maneuverable. These thrusters will change that.

Parachute problems again for NASA’s flying saucer

5:06 pm

In its second flight today NASA’s engineering vehicle for testing Mars landing technologies, dubbed a flying saucer by the press because of its shape, had a similar problem as in its first flight, with its parachutes failing to inflate properly during landing.

More here. This test was not only to check out landing technologies, it was to check out the redesigned parachute that had failed in the previous test last year.

NASA announces bold plan to still exist by 2045

8:50 pm

Heh.

“It may seem impossible now, but we hope to realize the vision of establishing a human presence in NASA deeper into the century than ever before imagined,” Bolden added.

When questioned about the plan’s viability, Bolden told reporters that while certain doubts remain, the project was nonetheless an absolutely crucial undertaking for NASA. Bolden further emphasized that the Fortuna Program’s goal was technically achievable on paper, and could feasibly be accomplished in a real-world scenario so long as everything “goes perfectly” for the space agency.

“The first critical step toward reaching our goal is to still be here by the year 2020,” said Bolden, adding that the plan allowed absolutely no room for error. “From there, we will move on to the next phase of the mission, which is to implement an intensive 10-year plan to remain operational. If we meet that goal in 2030, then there’s no reason to believe NASA won’t make it to 2045.”

Read it all. As far as I can tell, there really hasn’t been much difference between NASA’s past two decades and what this Onion piece proposes for NASA’s next three decades.

In fact, after you read the Onion piece above, then read this Orbital ATK press release about the successful results from the solid rocket booster test firing in March. As successful and as legitimate as the engineering was for the booster test, why does the press release sound so much like the Onion article?

A second experiment on the next X-37B flight revealed

5:28 pm

NASA has outlined the materials research it will be conducting on the next X-37B flight, scheduled to launch on May 20.

Known as the Materials Exposure and Technology Innovation in Space, or METIS, the investigation on the X-37B will expose nearly 100 different materials samples to the space environment for more than 200 days, NASA says. METIS is building upon data obtained by several missions of the Materials on International Space Station Experiment (MISSE), which flew more than 4,000 samples in space from 2001 to 2013. For both MISSE and METIS, small samples the size of quarters are used. METIS will fly a variety of materials including polymers, composites and coatings.

Not only does this information, plus earlier information about an Air Force ion engine thruster experiment, probably describe a great deal of what the X-37B is carrying, it also tells us the probable duration of the flight.

I have no doubt there are other classified Air Force experiments on board, but like these, they are likely to be test articles, since the X-37B provides the perfect testbed for exposing new technology to space to see how it fares.

NASA ISS cargo contracts delayed

8:15 am

The competition heats up: NASA has delayed, for the second time, when it will award its next round of cargo contracts to ISS, pushing the date back from June to September.

Though agency officials said they could not reveal why they had delayed the contract awards, they did say it was to gather more information. My guess is that the agency wants to see how SpaceX’s launch abort tests turn out this year before it makes a decision. If successful, they will then have the option of dropping SpaceX’s as a cargo carrier and pick someone else, possibly Dream Chaser, to provide up and down service to ISS. That way, they would increase the number of vehicles capable of bringing people and supplies up to ISS.

Delaying the award decision until September gives them time to evaluate the abort tests results, as well as give them a cushion in case those tests get delayed somewhat.

Incorrectly built SLS welding machine to be rebuilt

9:16 am

You can’t make this stuff up. A giant welding machine, built for NASA’s multi-billion dollar Space Launch System (SLS), needs to be rebuilt because the contractor failed to reinforce the floor, as required, prior to construction.

Sweden’s ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA’s Michoud Assembly Facility in New Orleans.

ESAB was supposed to reinforce Michoud’s floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, “but when you’re talking about something that’s 217 feet [66.14 meters] tall, that adds up,” May said.

Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of “a miscommunication between two [Boeing] subcontractors and ESAB.”

How everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract, baffles me. It also suggests that the quality control in the SLS rocket program has some serious problems.

Update: The original story at Space News that I originally linked to disappeared sometime in the next week, and was replaced with a slightly more detailed and more positive story, now linked above.
