The space shuttle program officially ended on Wednesday

9:23 am

The space shuttle program officially ended on Wednesday. Note however:

Closeout of the shuttle program is an enormous effort expected to take two years. The program occupied 640 facilities and used more than 900,000 pieces of equipment with a value exceeding $12 billion, according to NASA. Much of the work will take place at Kennedy Space Center, where orbiters have been maintained and prepared for launch. NASA requested $89 million for shuttle transition and retirement work in the 2012 fiscal year that begins Oct. 1, but Congress has not yet approved a budget.

When dust, pebbles, rocks, and boulders act like liquid

3:35 pm

The science team of Lunar Reconnaissance Orbiter released an intriguing picture yesterday of what scientists call a granular flow down the side of a five mile wide crater on the far side of the moon. Looking at the image, one would swear that the darker material flowing down the slope of the crater rim is a lava flow frozen in place.

However, according to the scientists, that is not what it is. Instead, this is merely debris left behind from an avalanche.

The immediate consequences of the Progress freighter failure

1:46 pm

The immediate consequences of the Progress freighter failure:

The longer term consequences? Congress will anguish over the lack of a shuttle. Some will demand more money for the program-formerly-called-Constellation, while others will demand more money for the new commercial companies. In either case, they will ignore the reality of a bankrupt federal government that simply can’t afford either at the moment.

NASA’s costs estimates too low for Congress’s heavy-lift rocket

9:55 am

Surprise, surprise! An independent analysis of NASA’s budget estimates to build Congress’s heavy-lift rocket, the program-formerly-called-Constellation, are untrustworthy and likely low.

“All three program estimates assume large, unsubstantiated, future cost efficiencies leading to the impression that they are optimistic,” the team said in its key findings. A risk assessment revealed the funding reserves projected for all three programs are insufficient, according to Booz Allen Hamilton. NASA has not disclosed its internal cost estimate for the Space Launch System. “Due to procurement of items still in development and large cost risks in the out years, NASA cannot have full confidence in the estimates for long-term planning,” the executive summary said.

This project is nothing more than Congressional pork. It will never get built. Sadly, it might waste a lot of money before it never gets built.

Bigelow in negotiations to supply privately-built modules to ISS

12:59 pm

Bigelow Aerospace is in negotiations with both NASA and Japan to supply ISS with privately-built modules

The module could be rented out as an ISS storage unit, making the station less dependent on frequent resupply flights, says Hiroshi Kikuchi of JAMSS. To show that the modules are capable of safe, crewed operation, Bigelow is also negotiating with NASA to attach one to a US-owned ISS module.

NASA announces awards for three technology demonstration space missions

2:47 pm

NASA has announced three awards for technology demonstration space missions, all set to fly within four years. More details here.

The three missions are:

  • A solar sail demonstration mission, flying a sail 38 by 38 meter sail.
  • A demonstration of in-space laser/optical communications technologies.
  • The use of a high-precision atomic clock in space.

I especially like the solar sail mission because of its long range possibilities, though the other technologies would probably be put to practical use more quickly.

The new commercial space companies question NASA contracting policies

3:02 pm

The new commercial space companies are challenging NASA’s new contracting policy.

The article covers the conflict that I described in this post, whereby NASA is abandoning the more flexible contracting approach used for the commercial cargo contracts of SpaceX and Orbital Sciences and going instead with the contracting system it used for all past NASA subcontracts.

The article is errs badly when it calls the new contracting approach that NASA wants to use “non-traditional.” It is instead the way NASA has been doing things for decades, whereby the agency takes full control of everything and requires contractors to fill out so much paperwork that the costs double and triple.

How the end of NASA affects national security

9:38 am

How the end of NASA affects national security.

Though I don’t agree with all of Dinerman’s points, he provides a complete and excellent analysis of the present political state of NASA. To me, the key quote is this:

NASA’s Administrator and his Deputy worked hard, along with the President’s science advisor and the rest of the White House team, to alienate a critical mass of members of Congress by ignoring their concerns, rejecting their advice and blindsiding them with critical space policy decisions. The Obama administration then wrecked the previous program on the grounds that it was underfunded and behind schedule, and replaced it with a new program that looks as if it is now underfund and behind schedule. Congressmen and women being human, and under massive pressure to cut spending, have now cut the guts out of the space agency’s proposed budget.

Senate Issues Subpoena to NASA for SLS Materials

2:16 pm

The space war over NASA continues: The Senate has issued a subpoena to NASA, demanding documents related to its plans for building the Congressionally-designed Space Launch System (SLS), what I like to call the-program-formerly-called-Constellation.

In related news, NASAspaceflight.com reports that those NASA documents state that the agency’s plans for building SLS will take 21 years (!), with the first flight not taking place until 2032.

No wonder NASA has stalled releasing these documents. Nor am I surprised. Based on the budget that Congress gave the agency, it is literally impossible for NASA to build this rocket any faster. And at that rate, no one should be surprised if it never gets built at all. Far better to cancel it now and save the taxpayers the money.
