Despite the astronauts’ success on ISS in recreating the spacesuit water leak, NASA engineers still do not know its cause.

Despite the astronauts’ success on ISS in recreating the spacesuit water leak, NASA engineers still do not know its cause.

What is unstated about this problem is that, because we used to have a big space shuttle with lots of cargo capacity, the American spacesuit was designed to be maintained and repaired on the ground. In the past the next space shuttle flight would have brought a new spacesuit to the station while taking this defective suit back to Earth for analysis and repair. Now that we don’t have a big space shuttle, our complex spacesuits are far more difficult to troubleshoot.

The solution? First, keep it simple. The Russians, limited by the capacity of their Progress and Soyuz capsules, made their Orlan spacesuit very simple and easy to use.

Second, get as many redundant replacements of the shuttle operating as soon as possible.

A NASA veteran slams SLS.

A NASA veteran slams the Space Launch System (SLS).

The problem with the SLS is that it’s so big that makes it very expensive. It’s very expensive to design, it’s very expensive to develop. When they actually begin to develop it, the budget is going to go haywire. They’re going to have all kinds of technical and development issues crop up, which will drive the development costs up. Then there are the operating costs of that beast, which will eat NASA alive if they get there. They’re not going to be able to fly it more than once a year, if that, because they don’t have the budget to do it. So what you’ve got is a beast of a rocket, that would give you all of this capability, which you can’t build because you don’t have the money to build it in the first place, and you can’t operate it if you had it.

Q: What do you see as the alternative?

A: In the private sector we’ve got an Atlas and a Delta rocket, and the Europeans have a rocket called the Ariane. The Russians have lots of rockets, which are very reliable, and they get reliable by using them. And that’s something the SLS will never have. Never. Because you can’t afford to launch it that many times.

In an effort to deal with their quality control problems the Russians plan to consolidate their space industries into a single company controlled by the government.

The Russian way: In an effort to deal with their quality control problems the Russians plan to consolidate their space industries into a single company controlled by the government.

This is not a good sign for the future competitiveness of the Russian aerospace industry. Consolidation will only reduce competition and innovation, while placing the government in control will only increase bureaucracy.

An Iranian news release today says that researchers at a local university have “designed and built” a manned spacecraft.

The competition heats up? An Iranian news release today says that researchers at a local university have “designed and built” a manned spacecraft.

Sounds very dubious to me. I suspect what really happened is that these Iranian university researchers did some work outlining their proposed design, and this has now been translated into a “built” spacecraft.

For the first time since arriving on Mars engineers have allowed Curiosity to drive itself.

For the first time since arriving on Mars engineers have allowed Curiosity to drive itself.

The 1-ton Curiosity rover used autonomous navigation for the first time on Tuesday (Aug. 27), driving itself onto a patch of ground that its handlers had not vetted in advance. The robot will likely employ this “autonav” capability more and more as it continues the long trek toward the base of Mars’ huge Mount Sharp, NASA officials said.

In autonav mode, Curiosity analyzes photos it takes during a drive to map out a safe route forward. The car-size rover used this ability on Tuesday to find its way across a small depression whose fine-scale features were hidden from Curiosity’s previous location.

China’s first unmanned lunar lander is now scheduled for launch before the end of the year.

The competition heats up: China’s first unmanned lunar lander is now scheduled for launch before the end of the year.

This mission is the second stage in their long term plans for unmanned lunar exploration. It began with an orbiter which mapped the surface in high detail, followed now by a lander, which will then be followed by a sample return mission.

It appears a programming error might have caused the scrub of Japan’s new Epsilon rocket launch yesterday.

It appears a programming error might have caused the scrub of Japan’s new Epsilon rocket launch yesterday.

The computer controlling the launch from the ground detected an abnormality in the rocket position but it was later found to be normal. “It may have been an elementary, but not serious, problem, ” said one of the experts, quoted by the Kyodo News agency. An inspection after the canceled launch found no abnormality with the attitude sensors mounted on the rocket or with the computer feeding the data to the ground, according to the Japan Aerospace Exploration Agency (JAXA).

This is a preliminary report, but sounds credible. The report also suggests that the Japanese are in no immediate hurry to launch but instead want to very carefully investigate the issue first. And as I said yesterday, this is really all good news for this new rocket.
