The developmental engineering successes of the new commercially-built private spaceships, Dragon, CST-100, and Dream Chaser, appears to be winning over Congress.

The article linked above is mostly about Boeing’s effort with its CST-100 spaceship, but within it was this significant paragraph:

Last week, the House Appropriations committees approved $500 million and Senate appropriators $775 million for commercial crew development as part of NASA’s 2014 budget. The first figure is well below the Obama administration’s $821 million request, a figure NASA Administrator Charles Bolden has characterized as essential to meet the 2017 objective. Nonetheless, agency and company managers believe legislators are losing their skepticism over a program that has so far committed $1.4 billion to competing vehicle designs from SpaceX, Sierra Nevada, Boeing and others. [emphasis mine]

Congress is still insisting that NASA spend far more for the Space Launch System (SLS), but they do appear to be increasingly less interested in cutting the new commercial crew program. Eventually, a light will go off in their dim brains and they will realize how much more cost effective this program is compared to SLS. I expect this to happen sometime in the next three years, It is then that SLS will die.

Note that I don’t have any problems at all with the above cuts to the commercial program. It is far better to keep these private efforts on a short leash, thereby forcing the companies to stay lean and mean, than to give them a blank check (as has been done in the past and with SLS) and thus allow them to become fat and lazy.

NASA is trying get some spare spacesuit parts onto a Russian Progress freighter, scheduled to launch Saturday, in its effort to fix its American spacesuits on ISS.

NASA is trying get some spare spacesuit parts onto a Russian Progress freighter, scheduled to launch Saturday, in its effort to fix its American spacesuits on ISS.

It must be emphasized that NASA still doesn’t know exactly what caused the water leak into that spacesuit during a spacewalk last week.

Under pressure from her fellow legislators, a Maryland congresswoman has withdrawn her proposal to close the Marshall Space Flight Center.

Business as usual: Under pressure from her fellow legislators, a Maryland congresswoman has withdrawn her proposal to close the Marshall Space Flight Center.

As I wrote yesterday, this is government, and our legislators don’t represent us, they represent the small number of employees at these specific government facilities. Gotta protect that pork!

This also illustrates quite nicely why NASA can’t build anything cheaply, which means it can’t build anything at all. The agency is saddled with too much expensive fat which it is not allowed to trim.

Congresswoman Mary Edwards (D-Maryland) has proposed merging two NASA centers to save money.

Congresswoman Mary Edwards (D-Maryland) is proposing a merger of two NASA centers to save money.

The amendment would establish a Center Realignment and Closure Commission that would be given six months to evaluate “[c]onsolidating all rocket development and test activities of the Marshall Space Flight Center and Stennis Space Center in one location” and recommend a location promising the greatest cost savings. The commission would also be asked to look at “[r]elocating all operations of the Marshall Space Flight Center to both the Stennis Space Center and Johnson Space Center.”

Now this is interesting. The Marshall Space Flight Center has been looking for a reason to exist for decades, since the end of the Apollo program. Any smart private company would have shut it down long ago to save money.

But then, this is government. The article, hostile to the idea of eliminating any government facility, describes quite succinctly why NASA can’t build anything cheaply and why nothing in government ever shrinks. Our legislators don’t represent us, they represent the small number of employees at these specific government facilities.

NASA has revised their plans for the 2017 and 2021 flights of its Orion capsule, making both flights more ambitious.

9:33 am

The competition heats up? NASA has revised their plans for the 2017 and 2021 flights of its Orion capsule, making both flights more ambitious.

[M]anifests have always pointed towards the first SLS/Orion launch being an uncrewed Exploration Mission (EM-1), which was baselined a validation flight that would send Orion on a 7-10 day mission around the Moon.

SLS and Orion would then endure a four year gap – again, mainly due to the advanced 2017 debut relating to ISS crew back up – before repeating a version of EM-1, this time as a CLO (Crewed Lunar Orbit) flight, with four astronauts spending three to four days orbiting our nearest neighbor, as opposed to heading directly home after passing around the Moon – a flight known as Exploration Mission -2 (EM-2).

Much to the surprise of some people deeply involved with SLS and Orion, the order came down from NASA HQ to realign EM-2, based around a 2019 mission tasked with hunting down and capturing an asteroid that would then be placed in the vicinity of the Moon within one to two years. EM-2 is also known as the Asteroid Redirect Crewed Mission (ARCM). [emphasis mine]

It has been my understanding that the plans for the 2017 unmanned test flight have previously described it as sending the Orion capsule into a high several thousand mile orbit, not to the Moon, in order to simulate a re-entry from lunar distances. Making that unmanned mission a lunar orbital mission makes it far more challenging. Similarly, it is incredibly risky to turn the next flight, the first manned flight for Orion, into a duplicate of this mission, or a flight to an asteroid. This will be the first time humans will have ever flown on Orion, and only the second time the capsule has been used. To then send those humans to the Moon or an asteroid seems downright foolish. Even the 1960s NASA, which was quite willing to run risks, would not have attempted such a plan.

It is my guess that the White House has recognized that SLS can’t survive politically with a launch rate once every four years and planned test flights that aren’t very exciting. They are therefore pushing NASA to accelerate the second mission (and first manned flight) from 2021 to 2019, while also making both flights more ambitious and therefore more salable to the public.

Whether this is possible, given NASA’s bloated bureaucracy, is the main question. Moreover, even at this accelerated pace SLS will be competing directly against the private sector, which I expect will continue to do things far faster and, more importantly, far cheaper. Against that competition SLS will be hard put to survive.

NASA’s Space Launch System, costing billions per year, will only make its second manned flight in 2025.

The competition cools off! NASA’s Space Launch System, costing billions per year, will only make its second manned flight in 2025.

SLS is to make its maiden flight in 2017, when it will carry an empty Orion crew capsule to near-Moon space and back. Another flight would follow in 2021 and, depending on factors both technical and political, could see a crew of astronauts travel to a captured asteroid NASA wants to redirect to a high lunar orbit using a yet-to-be-built robotic spacecraft.

Notionally, SLS would next fly in 2025, giving the rocket a launch rate of once every four years. NASA has been spending about $1.8 billion a year on SLS development, including construction of a rocket test stand in Mississippi, and associated launch infrastructure at the Kennedy Space Center in Florida. Add in the cost of the rocket’s companion crew capsule, the Lockheed Martin-built Orion, and the tab rises to nearly $3 billion a year. [emphasis mine]

At that launch rate, the NASA’s space effort is slower than China’s, which has a pace that I consider extremely tortoise-like.

But don’t worry, buckos! NASA will be keeping the seats warm in its thousands of government facilities, employing thousands of government workers doing little or nothing.

After ten years of operation, NASA has turned off its Galaxy Evolution Explorer (GALEX) space telescope.

After ten years of operation, NASA has turned off its Galaxy Evolution Explorer (GALEX) space telescope.

In a first-of-a-kind move for NASA, the agency in May 2012 loaned GALEX to the California Institute of Technology in Pasadena, which used private funds to continue operating the satellite while NASA retained ownership. Since then, investigators from around the world have used GALEX to study everything from stars in our own Milky Way galaxy to hundreds of thousands of galaxies 5 billion light-years away.

It appears this loan arrangement has now ended because of a lack of funds. Either way, it always baffles me when NASA shuts down a working science telescope merely because it has been operating for a long time. Eventually the space agency will call for a replacement, the building of which will be far more expensive than it would have been to keep the original in operation.

A NASA ion engine has successfully completed more than five and a half years of continuous operation.

A NASA ion engine has successfully completed more than five and a half years of continuous operation.

During the endurance test performed in a high vacuum test chamber at Glenn, the engine consumed about 1,918 pounds (870 kilograms) of xenon propellant, providing an amount of total impulse that would take more than 22,000 (10,000 kilograms) of conventional rocket propellant for comparable applications.

So, now what? Will this engineering achievement be filed away, like so many other past NASA engineering projects, or will it be used for something?

NASA picks 8 new public relations figureheads, calls them astronauts.

NASA picks 8 new public relations figureheads, calls them astronauts.

To put it bluntly, NASA presently can’t put any astronauts into orbit, and might not be able to do ever again. Any astronauts on NASA’s payroll will thus likely have to beg a seat on a spacecraft built by others. Eventually, that begging won’t get them anywhere, which means that the work these new astronauts will mostly do will be to sell NASA to the public.

In the past, the PR work of astronauts only consumed a significant part of their time. For the present and probably in the future, it will be the only work they do.

Which makes me question the need to hire these astronauts in the first place. If I had my druthers and ran NASA, I’d rather wait until I actually need some astronauts and then hire the pilots who are flying SpaceShipTwo.
