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.

NASA to use giant SLS rocket to launch cubesats

9:50 am

The giant SLS rocket that NASA is building for billions will be used to launch eleven tiny 30 pound cubesats into deep space.

With room for 11 small shoebox-sized CubeSats on the first test flight of NASA’s behemoth Space Launch System, agency officials have turned to scientists, industry and students to fill the slots in time for launch in 2018. NASA has selected three CubeSats developed by internal government teams for flight on the SLS demonstration launch, and officials announced last week two more top candidates that could be manifested on the mission.

These will be the first cubesats ever sent beyond Earth orbit. Using SLS to get them into space, however, is very incongruous, since the very concept of cubesats is small and cheap, while SLS is everything but.

The GAO discovers another out-of-control NASA project

6:56 pm

Government marches on! A new GAO report has found that NASA’s effort to upgrade the ground-based portion of its satellite communications system, used by both military satellites and manned spacecraft, is more than 30 percent over budget, with its completion now delayed two years to 2019.

Worse, the GAO found that this problem program was actually one of three that have had budget problems. And that doesn’t include the disastrously overbudget James Webb Space Telescope.

In its latest assessment of NASA’s biggest programs, the U.S. Government Accountability Office identified the Space Network Ground Segment Sustainment (SGSS) as one of three — not counting the notoriously overbudget James Webb Space Telescope — that account for most of the projected cumulative cost growth this year. The others are the Magnetospheric Multiscale Mission, which launched March 12, and the Ice, Cloud, and Land Elevation Satellite-2, or ICESat-2, mission, the congressional watchdog agency said.

The last two projects are part of the climate focus that Obama imposed on NASA.

NASA denies new space station partnership with Russia

9:12 am

NASA officials today denied they were negotiating a partnership with Russia to build a space station replacement for ISS, as suggested yesterday by the head of Russia’s space program.

I am beginning to suspect that the misunderstanding here comes from NASA head Charles Bolden, who is in Russia right now. Knowing Bolden, who is a nice guy who likes to make others happy, he probably said some nice feel-good, kumbaya things to the Russians during conversations with them, things like “We want to keep working together,” and “We will support your plans for your future space station whole-heartedly.” None of this was meant as a commitment, but the Russians might have taken these statements more seriously than Bolden realized.

U.S./Russian deal on space cooperation past 2024?

9:23 am

Russian news sources today described a news conference in Russia where it was announced that NASA and Roscosmos have come to an agreement about extending ISS until 2024, establishing common standards for manned vehicles, and to work together on building a new space station to replace ISS after 2024.

It appears that NASA head Charles Bolden is in Russia right now as part of the start of the year-long mission on ISS, and he has negotiated some agreement with Russia. If these reports are accurate, then it means that Russia has decided to work with the U.S. rather than go it alone on their next station.

All this assumes that future presidents and Congress agree with this proposal, a very big assumption indeed.

GAO denied access to Webb telescope workers by Northrop Grumman

11:04 pm

In a report as well as at House hearings today the GAO reported that Northrop Grumman has denied them one-on-one access to workers building the James Webb Space Telescope.

The interviews, part of a running series of GAO audits of the NASA flagship observatory, which is billions of dollars overbudget and years behind schedule, were intended to identify potential future trouble spots, according to a GAO official. But Northrop Grumman Aerospace, which along with NASA says the $9 billion project is back on track, cited concerns that the employees, 30 in all, would be intimidated by the process.

To give Northrop Grumman the benefit of the doubt, these interviews were a somewhat unusual request. Then again, if all was well why would they resist? Note too that the quote above says the cost of the telescope project is now $9 billion. That’s a billion increase since the last time I heard NASA discuss Webb. If the project was “back on track: as the agency and Northrop Grumman claim, than why has the budget suddenly increased by another billion?

Sierra Nevada makes deal with Houston airport authority for Dream Chaser landings

10:19 am

Sierra Nevada has made an agreement with Houston’s airport authority to use Ellington Airport there to land its Dream Chaser spacecraft.

This announcement is part of the public relations push going on right now as NASA prepares to award its next round of cargo freighter contracts to two private companies. Sierra Nevada has bid to use an unmanned version of Dream Chaser to launch that cargo.

Further SLS delays loom

9:32 pm

A report by NASA’s inspector general finds that the planned first launch of the SLS rocket in November 2018 is threatened with delay because the ground facilities at Kennedy might not be ready.

In a report released Wednesday, NASA’s Office of Inspector General warned that Ground Systems Development and Operations, or GSDO, may be hard-pressed to have Kennedy Space Center’s launch facilities ready on time. Ground systems are a critical piece of the SLS-Orion infrastructure. All three elements are tightly integrated, with ground systems requiring significant input from the rocket and capsule designs. “GSDO cannot finalize and complete its requirements without substantial input for the other two programs,” said Jim Morrison, the assistant inspector general for audits. “And NASA is still finalizing the requirements for those programs.”

Gee, I guess SLS isn’t getting enough money, as its budget is only about $3 billion per year (about six times what the commercial space program gets per year, a program that has already created two freighter systems for ISS and is now creating two manned ferry systems for ISS). Why don’t we give them more, so that even more won’t be done with the money we spend?

How NASA will use Bigelow’s privately built ISS module

8:55 am

Not much it seems. The key paragraph is this:

Once installed, BEAM will be largely sealed off from the rest of ISS, with astronauts entering it every four to six months to retrieve data from sensors inside it. Crusan suggested NASA will consider making greater use of the module over time as the agency becomes more comfortable with its performance. That would require additional work inside the module, he said, since it has no active life support system beyond some fans.

This story illustrates NASA’s sometimes incredibly over-cautious approach to new technology. I grant that space is difficult and that it is always wise to be careful and to test thoroughly any new technology, but NASA sometimes carries this too far. For example, it took NASA more than two decades of testing before it finally approved the use of ion engines on a planetary mission (Dawn). Similarly, inflatable modules were abandoned by NASA initially, and wouldn’t even exist if a private company, Bigelow, hadn’t grabbed the technology and flown it successfully.

Sierra Nevada introduces its cargo version of Dream Chaser

6:35 pm

The competition heats up: Sierra Nevada has unveiled a revised cargo version of Dream Chaser, competing for NASA next round of freighter contracts to ISS.

They have made a number of changes, but the most significant is the new folding wings, allowing the spacecraft to fit inside the fairings of most rocket systems. This also eliminates one of the concerns I have read about the previous design on whether its wings could have withstood exposure to the maximum atmospheric stresses experienced during launch.

Lockheed Martin enters the competition to supply cargo for ISS

5:42 pm

The competition heats up: Lockheed Martin has joined Sierra Nevada, Orbital ATK, Boeing, and SpaceX in bidding for NASA’s next contract to ferry cargo to ISS.

Lockheed’s proposal is different in that it proposes a two spacecraft operation. The cargo would be hauled up in a very simple storage bin, where a long-term orbital tug would grab it and take it to ISS. The idea is that they would only have to build and launch the complicated thrusters, robot arms, computers, and avionics of their cargo freighter once, thereby saving money.

Two companies will be chosen. Since the first competition back in the mid-2000s, when NASA picked SpaceX and Kistler for the first cargo round, the quality of the bids has improved remarkably. Back then, NASA had to choose from a bunch of new companies, none of which had ever done this before. The big companies (Boeing, Lockheed Martin) then poo-pooed the competition, saying that it couldn’t be done as cheap as the new companies claimed. After Kistler went under and was replaced by Orbital, they and SpaceX proved the big companies were wrong.

Now the competition includes all the big players, except that those big players are no longer offering expensive systems but cut-rate efficient designs that are as cost effective as SpaceX and Orbital’s first designs.

Magnetic field science satellites launched

9:26 am

An Atlas 5 rocket successfully launched four NASA research satellites Thursday night designed to study the behavior of the Earth and Sun’s magnetic fields at high resolution.

The quartet of observatories is being placed into an oblong orbit stretching tens of thousands of miles into the magnetosphere — nearly halfway to the moon at one point. They will fly in pyramid formation, between 6 miles and 250 miles apart, to provide 3-D views of magnetic reconnection on the smallest of scales.

Magnetic reconnection is what happens when magnetic fields like those around Earth and the sun come together, break apart, then come together again, releasing vast energy. This repeated process drives the aurora, as well as solar storms that can disrupt communications and power on Earth. Data from this two-year mission should help scientists better understand so-called space weather.
