Orbital Sciences has released an updated launch schedule for its Antares rocket and Cygnus capsule.
The significance?

The death of the double click.
The story includes some nice history behind the invention of the GUI.
Interestingly, I could probably count on one hand the times I have double-clicked on a computer, since I rarely use the mouse at all. Instead, I have found it is far faster to use the keyboard to access commands, files, programs, etc.
Is asteroid mining about to begin?
Considering some of the major players who are either investors or advisers for this company, this story could get very exciting when the company’s full plans are revealed on April 24.
The first stage of the Antares rocket is now vertical on the launchpad at Wallops Island in preparations for launch tests.
“Our spaceships to fly from here to Abu Dhabi to New Mexico in no more than an hour.”
The suggestion from this story is that not only will Virgin Galactic fly suborbital tourism flights out of Abu Dhabi, but the deal includes an effort to turn SpaceShipTwo into a transportation vehicle as well. Most interesting.
New simulations suggest that the magnitude of tsunamis predicted to hit Japan have been significantly underestimated.
The difficulty here is that these predicted giant tsunamis are still expected to be very rare events. It is thus unclear what is more practical, to build things at great cost so that they can survive these rare events, or to live with the risk and rebuild each time after disaster strikes.
There are really only two important stories today concerning space exploration. The story that is getting the most coverage is the big news that the space shuttle Discovery is making its last flight, flying over Washington, DC, as it is delivered to the Smithsonian for permanent display.
Of these stories, only Irene Klotz of Discovery News seems to really get it. This is not an event to celebrate or get excited about. It is the end of an American achievement, brought to a close probably three to five years prematurely so that the United States now cannot even send its own astronauts to its own space station.
The other news, actually far more important, has gotten far less coverage, and includes three different stories all really about the same thing.

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.
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.

ISS’s robot arm has now been moved into position in preparation for the Dragon berthing flight, scheduled for April 30.
The article also gives a nice outline of the entire Falcon 9/Dragon test flight.
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.
North Korea’s attempt to put its first satellite into orbit today was a failure, breaking up less than two minutes after liftoff.
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.

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.
More commercial space news: Orbital Sciences has rolled the first stage of its commercial Antares rocket to the launchpad for tests.
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.
Despite protests from the U.S. and South Korea, North Korea is continuing preparations for the launch an Earth observation satellite.
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.
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:
