NASA has decided that the best use for two space mirrors donated to the space agency by the National Reconnaissance Office (NRO) would be to study either dark energy and extrasolar planets.

There is no funding as yet for either mission, so for the moment the mirrors will remain on the ground, in storage.
The repairs to the cracks in the first Orion capsule have withstood static stress tests.
I’m so glad: The repairs to the cracks in the first Orion capsule have withstood static stress tests.
In addition to the various loads it sustained, the Orion crew module also was pressurized to simulate the effect of the vacuum in space. This simulation allowed engineers to confirm it would hold its pressurization in a vacuum and verify repairs made to superficial cracks in the vehicle’s rear bulkhead caused by previous pressure testing in November.
The November test revealed insufficient margin in an area of the bulkhead that was unable to withstand the stress of pressurization. Armed with data from that test, engineers were able to reinforce the design to ensure structural integrity and validate the fix during this week’s test. [emphasis mine]
I love how this NASA press release describes the cracking of the capsule bulkhead during the November testing, indicated in bold. “Insufficient margin”, eh?
Normally I am very forgiving when things fail during engineering tests, but for the bulkhead of this capsule to crack during these tests was actually pretty shameful, considering the decades of engineering work previously done in the building of space capsules and submarines. Things can certainly go wrong when you build something new, but I don’t see anything particularly revolutionary about Orion’s design. Lots of things might fail, but making sure the bulkhead could withstand the normal and well known stresses of spaceflight should not have been one of those things. The bulkhead failure suggests to me some sloppy engineering work took place in Orion’s initial design.
The Tortoise and the Hare
Smith looks at the published construction and flight timelines for the government’s Space Launch System and the private company Golden Spike, and finds something I’ve been noting for several years, there is a new space race going on. And I think private space will win it.
Another perspective — the one I have — is that this creates a new Space Race.
In the starting gate at High Bay 3 is the SLS, a program larded by Congressional pork, dubbed the Senate Launch System by its critics. Many observers believe that it will one day fall to innate political and bureaucratic flaws, as did Constellation before it.
In the other starting gate at High Bay 1 is Golden Spike — all talk so far, but the pieces seem to be falling into place to make the company a viable lunar option. Add to the mix the May 23 teleconference discussing the NASA agreement that allows Bigelow Aerospace to ally NewSpace companies into a possible commercial cislunar program. The report hasn’t been released yet, but it’s logical to assume that Golden Spike is one of those companies.
As with all space programs — government or commercial, crewed or unmanned — these timelines should be viewed with the greatest of skepticism.
But we’re starting to see all the pieces fall into place for the great Space Race of the 21st Century. To the victor goes access to the Final Frontier.

NASA Announces Plans To Put Man On Bus To Cleveland
Private space is winning
Today I attended an space industry conference here in Orange County, California, sponsored by the American Institute of Aeronautics and Astronautics. Unlike the Space Hackers conference which also occurred today and to which I was also invited, this was not a New Space get-together, but a standard aerospace event which included a lot of old time engineers from the big old-time companies like Boeing and Lockheed Martin.
Most of the talks today were engineering related. For example, one described in detail the engineering advantages of building ion engines and solar sails at the molecular level, nanotechnology to the max. Another talk, which I found astonishing and exciting, was an analysis of the orbital mechanics of getting to Mars. This analysis found that using constant acceleration as low as .01 G it would be possible to get to Mars in weeks, not years, and without the necessity of waiting for the perfect launch window. You could launch almost anytime. Though we don’t have engines that as yet can provide this much constant low acceleration, these numbers are not so high as to make it impossible. With some clever refinements, it might be possible to come up with propulsion systems capable of these constant Gs, and to do it in the near future. If so, it will open up the entire solar system to manned exploration very quickly. Not only will we be able to travel to the planets in a reasonable time, the constant Gs would overcome the medical problems caused by prolonged weightlessness.
It wasn’t these interesting engineering presentations that got my juices flowing however. Instead, it was presentation on public policy issues that completely surprised me and made me think the future of the American aerospace industry is really going in the right direction. This significant take-away was further reinforced by the audience’s reaction to my lecture in the evening.

The Chinese national who had been arrested at Dulles airport as he left for China with a NASA laptop has been released after pleading guilty to one charge, having porn on the laptop.
The Chinese national who had been arrested at Dulles airport as he left for China with a NASA laptop has been released after pleading guilty to one charge, having porn on the laptop.
Investigators found no classified information on the computer. As part of the release agreement, however, the man must leave the U.S.
Though the man, Bo Jiang, was very careful to bring nothing secret with him when he tried to flee to China in March, the circumstantial evidence suggests that he should not have had access to this information in the first place, and that in the past he might have illegally funneled classified information to China.

Lockheed Martin will begin intensive stress tests on its Orion capsule on April 22.
The competition heats up: Lockheed Martin will begin intensive stress tests on its Orion capsule on April 22.
Though the article makes no mention of the cracks that had previously been found in that capsule, nor the repair work that was done to fix them, I strongly suspect that these stress tests are aimed at testing these repairs.
Boeing is about to begin wind tunnel tests of its CST-100 manned capsule.
The competition heats up: Boeing is about to begin wind tunnel tests of its CST-100 manned capsule.
This is good, but there is something about the pace of development of the CST-100 that seems mighty slow to me. Last September there were indications that Boeing might shelve the project, which were countered in November by word that they were instead considering increasing their investment.
The slow pace suggests to me that management has rejected the latter. It also suggests that while they haven’t shelved the project, they are not pushing it hard, which means that eventually it will die because it will fail to compete with other more ambitious and competitive efforts.

He’s right. Instead, others will do it. And the ones who do it from the United States, privately financed for profit, will do it quickly, efficiently, and often, three things NASA has not been able to do at all since the 1960s.
