First 3D part manufactured in space

11:07 pm

Astronauts on ISS have used a 3D printer, shipped to the station on the last Dragon flight, to print the first item ever manufactured in space.

“Everything worked exactly as planned, maybe a little better than planned,” Kemmer told NBC News. He said only two calibration passes were needed in advance of the first honest-to-goodness print job, which finished up at 4:28 p.m. ET Monday and was pulled out of the box early Tuesday. “It’s not only the first part printed in space, it’s really the first object truly manufactured off planet Earth,” Kemmer said. “Where there was not an object before, we essentially ‘teleported’ an object by sending the bits and having it made on the printer. It’s a big milestone, not only for NASA and Made In Space, but for humanity as a whole.”

The part made was a faceplate for the printer itself. This printer is a demonstration project, launched to test the engineering and to see how 3D printing operates in weightlessness. Eventually the goal is to have most of the spare parts on a interplanetary vehicle manufactured in space in this manner, using a supply of standard material, called feedstock, that would be much cheaper to ship from Earth.

Italy’s legislature rejects additional funding for space

12:11 am

The Italian legislature has refused to add an additional $250 million to the budget of its space program, money requested to help pay the country’s share in the development of Arianespace’s next generation commercial rocket, Ariane 6.

The money was also needed for several other ESA space projects. Not having it puts a question mark on Italy’s future in space. The article also illustrates how the committee nature of Europe’s cooperative space effort makes it almost impossible for it to compete in the commercial market.

Cygnus on Falcon 9?

11:36 pm

The heat of competition: Industry rumors now suggest that Orbital Sciences’s first choice for launching its next ISS freighter Cygnus is SpaceX’s Falcon 9.

The articles offers this explanation for why Orbital is favoring its chief competitor:

While flying on a competitor’s launch vehicle might be viewed as awkward, the decision could boil down to one simple determining factor – cost. It has been estimated that a flight on a F9 would set a customer back $62 million. By comparison, United Launch Alliance’s (ULA ) Atlas V 401 launch vehicle, a booster with similar capabilities to the F9, costs an estimated $100 million per mission. Moreover, SpaceX has a proven track record with the Falcon 9.

All true, but I can think of two more reasons SpaceX is the top choice.

Obama proclaims he will fail to do what every President has failed to do since Carter and the right goes crazy.

11:17 pm

I was reading Newt Gingrich”s commentary blasting Obama for his immigration amnesty announcement and was struck by this paragraph:

[Under Obama’s directive] there will be one group, estimated at 4 million or so, who are eligible for the new work authorization program. But at the same time, there will be no resources directed at enforcing immigration law against the other 7 million people here illegally as long as they do not fall into a few narrow categories, according to the President’s Office of Legislative Affairs. And indeed, a “senior administration official” told Roll Call that the administration “will order immigration agents to prioritize deportations of criminals and recent arrivals — and let people who are not on that priority list go free.”

I read this and realized that what Obama is doing, or not doing, depending on your point of view, is exactly what every President since Carter has done or failed to do. For the right to blast him for this unconstitutional behavior is fine, but we mustn’t forget that Republican presidents have been just as corrupt and as unconstitutional. Since the 1970s the executive branch of our federal government has simply failed to enforce the immigration laws that exist, in exactly the way Obama outlined it, and the result has been the arrival of millions of illegal immigrants inside the United States.

All Obama has done is admit to this failure, and draped it in the mantle of his approval. Past presidents had instead made believe they were doing their constitutional duty, even as they quietly allowed immigration officials to cease enforcing the law. Why else are so many illegals here?

It is this failure, by Presidents of both parties, that ipitomizes the corruption and failure of the federal government on all issues. From the budget to immigration to healthcare to pushing for wasted funding for SLS, our federal government is a pile of garbage that is choking the life out of American society, on all levels. It is for this reason that I heartily and without fear routinely support the election of untried and sometimes foolish sounding tea party candidates: they can’t possibliy be worse than what we already have and — because of their passion for smaller government — are far more likely to be much better.

Accidental freon release inside ISS

12:44 pm

While doing maintenance to the air-conditioning system on the Russian portion of ISS two Russian astronauts accidently vented freon into the station’s atmosphere.

“Cosmonauts Samokutyaev and Serova performed steps to release pressure in the Russian segment’s air conditioner system by venting khladon gas (Freon 218) overboard. However, several of the quick disconnects that were actuated during the procedure exhibited leaks. As a result, the Khladon was vented into the cabin instead. The quantity released was approximately 100 g, which results in a density of 117 mg/m3 over the volume of ISS, which was below the stated ISS zero risk flight rule limit of 150 mg/m3. As part of nominal air scrubbing process, the Russian Air Purification System and the USOS Trace Contaminant Control System (TCCS) will remove residual Khladon from the atmosphere,” the NASA blog said.

MAVEN in safe mode

9:10 pm

A timing conflict between two computers on board MAVEN has put the Mars probe into safe mode.

The issue seems relatively minor and something that engineers should resolve without difficulty. Even so, I refuse to use the bureaucratic term “glitch” to describe it, as the article does, as this term is often employed by government employees to disguise much more serious problems. Journalists shouldn’t help them do this.

Kickstarter campaign to fund lunar probe

7:55 am

The competition heats up: A private consortium of scientists and entrepreneurs is planning to fund its unmanned lunar lander with a Kickstarter campaign followed by private sales..

The mission is raising initial development funding through Kickstarter, the crowdfunding platform. Following the initial public phase the remaining funding requirements will be met through sales of ‘digital memory boxes’ in which donors can have their biographies recorded and taken to the Moon. These will also include a strand of hair so that their DNA can exist in space. The team has claimed that around one per cent of the global population who can afford a memory box will buy one. Also included in the time capsule will be record of life on Earth. The archive will include a record of human history and civilisation to date alongside a species database showing the biodiversity of animals and plants.

This is essentially a UK project, backed by the government but with little funding. They hope to launch in 2024, with two missions planned, the first to drill into the lunar soil and the second to bring back samples.
