A new record for the longest Rube Goldberg machine
An evening pause: The Purdue Society of Professional Engineers team set a new record last week for longest ever Rube Goldberg machine, taking 300 steps to flawlessly blow up and then pop a balloon.

ULA, NASA’s prime contractor for operating the space shuttle, on Friday laid off nine percent of its work force.
USA, NASA’s prime contractor for operating the space shuttle, on Friday laid off nine percent of its work force.
I honestly have to ask: why did it take so long? The last shuttle flight was in July of last year. It couldn’t possibly have required that many people to prepare these spacecraft for display in museums.
Update: Typo corrected. Thank you Erik.

Some wisdom from Pravda: “Humans explore space only for profit.”

And then there’s this, from the U.N., not surprisingly published at MSNBC: “Private property in outer space: The other side of the argument.” To quote the U.N. expert: “More rules are needed, but I am also of the opinion that you do not need to create property rights [in space].”
It is a sad world when support for capitalism, private property rights, and competition comes from Pravda, while in the U.S. such ideas get slapped down.

Europe’s primary Earth-observation satellite has gone silent.
Europe’s primary Earth-observation satellite, Envisat, has gone silent.
Launched in 2002, the satellite is billed as the most sophisticated environmental monitor in orbit, with ten instruments providing streams of valuable data on everything from ozone, clouds and greenhouse gases to land-use trends and sea-surface temperatures — data that have figured in more than 2,000 scientific publications, ESA says. Over the years, Envisat has also offered a unique vantage point on major environmental disasters such as the December 2004 earthquake and tsunami in southeast Asia and the Deepwater Horizon oil spill in the Gulf of Mexico in 2010. Now, scientists fear that the satellite’s decade-long run has come to an abrupt end.
Problems began on 8 April when the satellite’s signal cut out as it was passing over a ground station in Sweden. ESA has been working with a team of scientists and engineers to diagnose the problem and to re-establish contact, but the outlook remains unclear.

European subsidies have put Arianespace in the black.
European subsidies have put Arianespace in the black for 2011 and 2012.
The key quote however is this:
But ESA governments have made clear they are not happy having to cover losses, especially since the workhorse Ariane 5 rocket, introduced in the mid-1990s, is well past its teething stage and has conducted 47 consecutive launch successes. Its last failure was in late 2002.
Arianespace has dominated the commercial launch market in recent years, yet can’t make a profit. In this case, however, I suspect that if the company lost its subsides it would somehow find a way to finally reduce its budget.

Assuming it gets the necessary funds, Boeing anticipates flight tests of its CST-100 reusable manned capsule in 2016.
More news from commercial space: Assuming it gets the necessary funds, Boeing anticipates flight tests of its CST-100 reusable manned capsule by 2016.
This story is part of the on-going lobbying effort to convince the Luddites in Congress to subsidize the new commercial space companies. To get some context, even if Congress gives NASA all of the money it has requested for this program, the annual cost will still be less than a third of the NASA-built Space Launch System, and will get us four different ways to get humans and cargo into orbit, and do it in far less time.

Virgin Galactic has been cleared by the State Department to fly foreign tourists without obtaining an export license.
Good news: Virgin Galactic has been cleared by the State Department to fly foreign tourists without obtaining an export license.
[Mark Sundahl, an associate professor of law at Cleveland State University in Ohio], said that without this determination from State, allowing a non-U.S. citizen to ride in a Virgin spacecraft — or even training a non-U.S. citizen to do so — would legally have been an export activity that required federal approval. The time it takes to obtain an export license varies, but several months is a reasonable estimate, said Sundahl, who specializes in international commerce and space law. “Under ITAR, any disclosure of controlled technical data to a foreign national, even if the disclosure takes place in the U.S., is treated as an ‘export’ of the technical data — which would require a license from the Department of State in addition to imposing other regulatory burdens on the exporter,” Sundahl said.
Freed from this regulatory requirement will make it easier for Virgin Galactic, as well as others, to sell tickets.

North Korea recently entered into a food aid agreement with the U.S., which requires the Asian nation to halt long-range rocket launches in exchange for critical resources to stem the country’s widespread poverty and famine.
Officials from the U.S. and South Korea have said that the Unha-3 launch is a violation of this agreement, and could carry significant consequences. South Korean officials have said they may even shoot down parts of the Unha-3 rocket if they breach the state’s borders.

SpaceX is planning its own spaceport about three miles north of Mexico at the southern tip of Texas.
SpaceX had been looking at sites at various potential sites, including ones in Florida, Hawaii and Puerto Rico. Company officials have said they plan to operate out of Cape Canaveral and Vandenberg Air Force Base as well. A third, commercial launch site frees them from range restrictions that exist at the other two locations.

The actual cost to launch
In writing this short post on the efforts of Lockheed Martin and Orbital Sciences to launch rockets for the small satellite market, Clark Lindsey made this comment:
It costs around $50 million to launch a Orbital Sciences Minotaur 4, which can put 1,730 kg into LEO while the Lockheed’s Athena 2 will cost around $65 million to put 1,712 kg into LEO. SpaceX currently posts charges $54M – $59.5M for launching to LEO 10,450 kg (equatorial) and 8,560 kg (polar). If SpaceX is able to sustain these prices in routine operation, it will obviously result in some disturbance to the launch industry.
Let’s deconstruct these numbers again, this time listing them by the cost per kilogram:

Europe has shut down the production line producing their ATV cargo craft for ISS.
Is this good or bad news? Europe has shut down the production line producing their ATV cargo craft for ISS.
Confronted by parts obsolescence and waning political support, the European Space Agency has shut down subsystem production lines for the Automated Transfer Vehicle as member states debate how they will contribute to future international space exploration efforts, according to top spaceflight officials.
ESA has launched three of the five ATVs it agreed to launch, with the remaining two scheduled in 2013 and 2014. What happens after that remains unclear. It seems from the article the European partners don’t seem interested in upgrading the ATV, and instead seem willing to let the as-yet untried U.S. commercial companies carry the load.
Commercial flights by U.S. spacecraft will make up the rest of the lost capacity with the end of the ATV program.
The pressure continues to build on a successful Falcon 9/Dragon flight on April 30.
