Building a scale model of the International Space Station — using matchsticks!

Building a scale model of the International Space Station — using matchsticks!

Recently completed by Acton, the wooden ISS is as impressive in size as it is in detail. Comprised of 282,000 matchsticks, the 1/26 scale model required 8 gal (30 L) of glue and took roughly 1,950 hours to complete. Whereas the actual ISS measures out at 108.5 m (356 ft) wide and 72.8 m (239 ft) long, Acton’s scaled down version measures out at an impressive 4.1 m (13.5 ft) and 2.8 m (9.2 ft) wide. Solar arrays, trusses, communication components, and even the Space Shuttle Atlantis, are all there in intricate detail.

How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.

How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.

A very interesting read, as it outlines the specific technical problems faced by engineers that one wouldn’t normally consider. The capsule has to be able to remain functional and reliable after months in orbit, but it also has to become functional at a moment’s notice, should an emergency happen.

The porksters arrive!

9:01 am

A draft bill in Congress is proposing the Pentagon develop an engine for the Atlas 5 engine to replace the Russian engine now used.

The legislation passed by a House subcommittee Wednesday calls for up the U.S. military to spend up to $220 million next year to kick off full-scale development of the engine, which could be ready for flights no later than 2019. The bill states the Defense Department “should develop a next-generation liquid rocket engine that is made in the United States, meets the requirements of the national security space community, is developed by not later than 2019, is developed using full and open competition, and is available for purchase by all space launch providers of the United States.”

There is no reason for this funding gift to the aerospace industry. For one thing, there are two rockets that already exist that use all U.S. parts, the Delta family of rockets and the Falcon 9. For another, if Congress stays out, the private sector will take care of this need and do it for a lot less and far quicker, while costing the taxpayers relatively little. By making this a government project we guarantee it will be expensive and take forever, thus keeping the pork flowing to Congressional districts without solving the problem.

And speaking of keeping pork flowing to Congressional districts, pork king Senator Richard Shelby (R-Alabama) today ripped into NASA for trying to trim a little from the budget of SLS (which sends a lot of cash to Alabama). He also condemned NASA’s manned commercial effort.

In addition to my May 6 at 7 pm (Pacific) appearance on the Space Show with David Livingston to discuss the situation with the Russians and ISS, I am also going to appear on Coast to Coast with George Noory on May 7 from 10 to 11 pm (Pacific) to discuss the same topic.

The Russian situation is a difficult one for the United States, and the reason it is difficult is because of a long series of incredibly stupid decisions by our elected officials, from both parties, for the past decade. Nor is my complaint here 20-20 hindsight. From the day George Bush proposed retiring the shuttle in 2010 and not replacing it until 2014, at the earliest, I have said this is stupid and astonishingly short-sighted. Sadly, Congress liked Bush’s short-sightedness and has been endorsing it now for a decade. Hearing them complain now about our dependence on Russian space capabilities is more than infuriating. Where were they when they might have done something to prevent this situation?

Listen in. I think it will be entertaining.

I will be making a special appearance on the Space Show this coming Tuesday, May 6, at 7 pm (Pacific) to discuss at length how the political friction between the United States and Russia over the Ukraine might impact the situation at ISS.

Should be quite fun. Feel free to tune in and to call in questions.

More delays seen in the completion of a new and critical module to the Russian portion of ISS.

More delays seen in the completion of a new and critical module to the Russian portion of ISS.

The delays have nothing to do with the Ukraine and everything to do with poor quality control in the Russian company building the module.

This quote stood out however:

With its central position in the architecture of the Russian segment, the MLM’s troubles also stall the launch of all subsequent Russian components of the station, including the Node Module, UM, (already under construction) and the NEM laboratory and power supply module, whose full-scale development started in 2012.

Given such a prolonged delay, combined with worsening political relations between Russia and its partners in the ISS project, the questions were raised whether the MLM module and the successive components of the Russian segment could be grounded until the assembly of the new all-Russian station in the post-ISS era. Under such a scenario, the troubled spacecraft could play a role of an early hub for the future orbital outpost.

If the Russians get enough modules built to launch their own station, I expect them to do it and cut their ties with ISS.

Russia responds to new U.S. sanctions by threatening U.S. astronauts on ISS.

10:06 am

Uh-oh: Russia responds to new U.S. sanctions by threatening U.S. astronauts on ISS.

Moscow reacted with fury to the inclusion in the sanctions of high-tech exports to Russia and threatened reprisals. “If their aim is to deliver a blow to Russia’s rocket-building sector, then by default, they would be exposing their astronauts on the ISS,” Russian Deputy Prime Minister Dmitry Rogozin said, according to the Interfax news agency.

“Sanctions are always a boomerang which come back and painfully hit those who launched them,” added Rogozin on a visit to Crimea, which Russia annexed from Ukraine in March. [emphasis mine]

Was Rogozin actually hinting that Russia might strand U.S. astronauts on ISS?

Russia has noticed literally no change in cooperation with NASA since the U.S. government announced two weeks ago that all such cooperation, excluding ISS, was being cut off.

Surprise, surprise! Russia has noticed literally no change in cooperation with NASA since the U.S. government announced two weeks ago that all such cooperation, excluding ISS, was being cut off.

Russia’s Roscosmos space agency has yet received no official notifications from NASA on curtailing cooperation, and working contacts continue, Roscosmos chief Oleg Ostapenko said in an interview with Vedomosti newspaper Wednesday. “Roscosmos has received no official notifications on suspending cooperation, we continue working contacts with NASA and other space agencies,” Ostapenko told Vedomosti adding: “Recently I held talks with the NASA leadership and European colleagues.”

More info here.

I had said that so-called NASA cut-off was all show and aimed not at Russia but at Congressional budget negotiations over NASA’s commercial crew program. This story only proves it.

Data now suggests that SpaceX successfully achieved a controlled landing of its Falcon 9 first stage on Friday.

6:56 am

The competition heats up: Data now suggests that SpaceX successfully achieved a controlled landing of its Falcon 9 first stage on Friday.

The stage itself has not yet been recovered due to heavy seas, but all evidence points to a soft splashdown in the ocean. While I expect them to continue to do this over the ocean, until they get good footage of the landing as well as recover the stage, the next real step is to land the thing over land. The link above also has video of the vertical take-off/landing of Falcon 9R on Friday, which proves they are beginning to prove this capability as well.

In related news, Dragon was successfully berthed to ISS today.

The backup computer that helps operate ISS’s robot arms is not responding to commands.

The backup computer that helps operate ISS’s robot arms is not responding to commands.

The timing could not be worse.. Though the number one computer is functioning fine, this unit is essential for controlling the robot arm that will berth Dragon to ISS this week.

Side note: The article above described this problem in its headlines as a “glitch.” I despise this word, as it is generally used by government bureaucrats to minimize the seriousness of a failure. The Soviet era bureaucrats in Russia loved it. I have noticed it popping up in American news reports relating to space more and more, and it is never a very accurate description of the situation. This computer failure is not a “glitch,” it is a serious failure of an essential piece of hardware.

Update: Because a spacewalk will be required to fix the backup computer, NASA has okayed the launch of Dragon. They need it to arrive first because it carries a new spacesuit and other parts needed to replace the suit that almost drowned an astronaut during a spacewalk last summer.

Note: I was in the back country of Arizona this past weekend, caving, which is why I am only now getting up to speed on this weekend’s news.
