The flight of gifted engineers from NASA

5:43 pm

Rather than work in NASA, the best young engineers today are increasingly heading to get jobs at private companies like SpaceX and XCOR.

It is a long article, worth reading in its entirety, but this quote will give the essence:

As a NASA engineering co-op student at Johnson Space Center, Hoffman trained in various divisions of the federal space agency to sign on eventually as a civil servant. She graduated from college this year after receiving a generous offer from NASA, doubly prestigious considering the substantial reductions in force hitting Johnson Space Center in recent months. She did have every intention of joining that force — had actually accepted the offer, in fact — when she received an invitation to visit a friend at his new job with rising commercial launch company SpaceX.

Hoffman took him up on the offer, flying out to Los Angeles in the spring for a private tour. Driving up to the SpaceX headquarters, she was struck by how unassuming it was, how small compared to NASA, how plain on the outside and rather like a warehouse.

As she walked through the complex, she was also surprised to find open work areas where NASA would have had endless hallways, offices and desks. Hoffman described SpaceX as resembling a giant workshop, a hive of activity in which employees stood working on nitty-gritty mechanical and electrical engineering. Everything in the shop was bound for space or was related to space. No one sat around talking to friends in the morning, “another level from what you see at NASA,” she said. “They’re very purpose-driven. It looked like every project was getting the attention it deserved.”

Seeing SpaceX in production forced Hoffman to acknowledge NASA might not be the best fit for her. The tour reminded her of the many mentors who had gone into the commercial sector of the space industry in search of better pay and more say in the direction their employers take. She thought back to the attrition she saw firsthand at Johnson Space Center and how understaffed divisions struggled to maintain operations.

At NASA young engineers find that they spend a lot of time with bureaucracy, the pace is slow, their projects often get canceled or delayed, and the creative job satisfaction is poor. At private companies like SpaceX, things are getting built now. With that choice, no wonder the decision to go private is increasingly easy.

NASA headquarters staff votes to unionize.

4:56 pm

NASA’s bureaucracy marches on: The staff at NASA headquarters today voted to unionize.

“This successful vote will allow us to work with management to improve working conditions for NASA support and administrative staff here at NASA headquarters, thereby improving operations, saving money, and retaining an engaged and professional workforce,” said Tifarah Thomas, a program specialist within NASA’s Office of the Chief Health & Medical Officer. Professional support specialists at NASA headquarters include budget analysts, policy analysts, administrative specialists, secretaries, and others.

NHPA currently represents nearly 200 engineers and scientists at NASA in Washington. The combined unit, including the professional support specialists who voted today for IFPTE representation, will now represent more than 500 workers at the headquarters of America’s space agency. IFPTE also represents engineers and scientists at NASA labs and research facilities from coast-to-coast.

Anyone with the slightest objectivity knows that the working conditions for federal employees in Washington is glorious, with pay about double what everyone else in the country makes and benefits far exceeding even the best private packages. In addition, the hours are great and just slightly longer than what my generation would have called bankers’ hours. Moreover, if I can be blunt, these engineers are mostly paper pushers. They are not the one’s designing and building anything that might fly in space. Their only reason to unionize now is because they see a threat to their cushy jobs with the advent of private space and are organizing to secure their unneeded positions.

NASA admits that it is struggling to meet the 2017 launch date for SLS

11:13 pm

Delays in the construction of Orion’s European-built service module as well as cracks in the spacecraft’s heat shield are threatening the planned 2017 launch date for Orion’s first test flight, unmanned, beyond Earth orbit.

Note that this program, costing anywhere from $10 to $20 billion, is only building a handful of capsules for flying three or four test flights. Beyond that, there is no money.

I have predicted this before, and I will predict it again: SLS will never take any humans anywhere. The cost is too high, the bureaucracy too complex, and the schedule is too slow. It will vanish when the new private companies begin flying humans into space in the next three years.

The Dream Chaser test vehicle to fly again

10:08 am

The competition heats up: Sierra Nevada has announced that its Dream Chaser engineering test vehicle has been refurbished and will complete a number of manned and unmanned flight tests in the fall, with their schedule on track for a November 2016 orbital test flight.

“We will do between two and five additional flights. A couple will be crewed. As a result of the vehicle being upgraded, we will be flying our orbital flight software, which will give us about a year’s worth of advancement on the vehicle.” Flights are expected to last over a six- to nine-month period, he adds.

Sierra Nevada has also continued to expand its partnerships, both in the aerospace industry as well as with other countries. The first action is likely part of a lobbying effort to help convince NASA to choose it when it down selects its commercial manned program from three manned spacecraft to two later this year. The second action indicates that even if Sierra Nevada is not chosen by NASA, they plan to proceed to construction anyway to serve other customers.

Orion first test flight scheduled

10:00 am

NASA has set December 4 for the first test flight of Orion.

In related news, the Navy has successfully completed a splashdown recovery test of Orion.

I haven’t labeled these stories “The competition heats up” because I have serous doubts Orion or SLS will survive the next Presidential election, even if this test flight on a Delta 4 Heavy rocket is a complete success. And if you want to know why, just read the first article above. It lists the long troubled ten-year long history of this capsule, with the following punchline describing the schedule for further launches with the actual SLS rocket:

While the first SLS/Orion mission, known as EM-1, is still officially manifested for December 15, 2017 – internally that date has all-but been ruled out. Internal schedules shows EM-1 launch date as September 30, 2018, followed by the Ascent Abort (AA-2) test – required for crew launches – on December 15, 2019, followed by EM-2 on December 31, 2020.

I find also find it interesting that in describing the many problems Orion has had in development, the article fails to mention the cracks that appeared in the capsule that required a major structural fix. Nor does the article mention the ungodly cost of this program, which easily exceeds $10 billion and is at least four times what NASA is spending for its entire program to get three different privately built spaceships built in the commercial program.

The next U.S. Mars rover will try to make and store oxygen

9:59 am

Of the seven science instruments proposed for the next U.S. Mars rover, scheduled for a 2020 launch date, MOXIE test the engineering to produce and store oxygen, pulled from the Martian atmosphere.

Developed in partnership with NASA’s Jet Propulsion Laboratory, it’s based on the fact that the Martian atmosphere, though extremely thin, is composed of 96 percent carbon dioxide, which means its a vast potential source of oxygen for future explorers and settlers. Essentially, MOXIE is a fuel cell in reverse. Instead of generating electricity by using oxygen to burn a fuel, it uses a process called solid oxide electrolysis , where electricity is employed to split carbon dioxide into oxygen and carbon monoxide.

This process would see Martian air pumped into the unit through a dust filter and pressurized before being passed into a fuel cell. At high temperatures, some ceramic oxides act as oxygen ion conductors. In the fuel cell, a thin, non-porous disc of this ceramic separates two porous electrodes. One electrode acts as the cathode and the other as the anode. Carbon dioxide passes through the cathode and when it comes into contact with the ceramic, the interaction of electricity and the ceramic causes the carbon dioxide to split into oxygen and carbon monoxide. The oxygen and the carbon monoxide are then separated and the oxygen stored.

What makes this unusual is that NASA has actually dedicated one science instrument to engineering research, not pure science. The agency does not do this much anymore, but such research is essential if the U.S. is going to someday send humans to other planets.

Russia outlines its space exploration plans for the next two decades

9:21 am

At a science conference in Moscow on Saturday the director of Russia’s Space Research Institute described in detail the future exploration plans for the Russian space program.

According to the story, Russia plans to return to the Moon and Mars with unmanned probes. He also described how the first missions will be in partnership with Europe, followed by Russian missions designed to test and prove the technologies. If these flights go well, in 2024 Russia will consider trying again with a repeat of the Phobos-Grunt mission that failed in 2012

This last detail is a change from previous reports that said Russia would launch Phobos-Grunt 2 in 2018. It is also consistent with much of the Russian program for the last two decades (as well as most of NASA’s own ambitious manned exploration program), where the agency makes bold announcements of future plans but somehow with each new announcement the dates for the actual launch have always been pushed back. The actual flight never seems to happen.

Commercial communications satellites for Mars?

8:03 am

The competition heats up? NASA is considering a different commercial approach for providing communications to and from its Mars probes.

The purpose of NASA’s request for information, or RFI, released July 23 “is to explore new business models for how NASA might sustain Mars relay infrastructure, consisting of orbiters capable of providing standardized telecommunication services for rovers and landers on the Martian surface, in the Martian atmosphere, or in Mars orbit,” according to a posting on the Federal Business Opportunities website.

According to the post, NASA will use information it receives from respondents to inform its future Mars exploration strategies, but the agency has not decided to pursue a commercial interplanetary telecom initiative. “We are looking to broaden participation in the exploration of Mars to include new models for government and commercial partnerships,” said John Grunsfeld, associate administrator of NASA’s science mission directorate, in a statement. “Depending on the outcome, the new model could be a vital component in future science missions and the path for humans to Mars.” [emphasis mine]

It is important to highlight the fact that NASA has not yet made a decision on this issue. The best thing the agency could do, in my opinion, would be to step back, design nothing, but let private companies bid on providing the service. The expertise at many of the private satellite companies providing communications efficiently and inexpensively to private customers worldwide would easily provide NASA better communications at Mars for less money.

In other words, like manned flight and cargo delivery to ISS, NASA should simply become a customer, and let private companies build and own the products that NASA buys.

Sierra Nevada signs deal with Japan

9:14 am

The competition heats up: Japan has signed a development agreement with Sierra Nevada in connection with its Dream Chaser manned spacecraft.

I was also tempted to preface this post with the phrase, “Who needs NASA?” Sierra Nevada has a viable product that can get humans into space cheaply. Several countries, Germany, now Japan, want to get their own citizens into space, and have realized what a bargain Dream Chaser is. Sierra Nevada is taking advantage of this demand to sell its product worldwide. If Congress decides to defund them, or NASA decides not to pick them to continue development, they very clearly intend to build the ship anyway. It just won’t be used to put American astronauts into space.

Another ISEE-3 update

2:24 pm

The team trying to resurrect ISEE-3 had very mixed results in its attempt today to get the spacecraft’s propulsion system working.

They managed to get “several instances of thrust,” which suggests there is fuel, the system can function, and that their strategy is on the right track. They did not however get full thrust as hoped, and are not quite sure why the spacecraft only partly responded. They are analyzing the data while they apply to NASA for an extension of their license to transmit to the spacecraft.

This last point is merely a formality. What can NASA do if they continue anyway? Nothing. NASA will say yes, partly because it is good public relations and partly because most of the people at NASA are also fans of this effort.

Space junk damages ISS coolant radiator?

9:09 am

According to the Russian Interfax news agency, a piece of space junk has hit a coolant radiator on the U.S. portion of ISS.

The source says that no coolant has escaped from the system and that NASA engineers are analyzing images to assess the damage.

Readers should be aware that I have tried without success to find the NASA website the story claims is the source for this information. Moreover, this story is reported nowhere in the U.S. press, and it is strange for a NASA website to report something like this and it not be quickly picked up by the U.S. press.

Thus, I am not entirely convinced yet that this story is accurate.

Update: a commenter below has provided this link to a subsequent post at nasaspaceflight about the impact.

NASA and Boeing finalize contract to build the SLS rocket

3:37 pm

NASA and Boeing today signed a $2.8 billion contract for Boeing to build the core stage of the SLS rocket

Scheduled for its initial test flight in 2017, the SLS is designed to be flexible and evolvable to meet a variety of crew and cargo mission needs. The initial flight-test configuration will provide a 77-ton capacity, and the final evolved two-stage configuration will provide a lift capability of more than 143 tons.

It would be nice for the U.S. to have this heavy-lift rocket, but I fully expect the funds to run out immediately after it makes its inaugural flight, despite the wonderful pork it provides to so many Congressional districts. It just costs too much per launch.
