SpaceX has delayed the launch of its Dragon test mission to ISS, with the launch now scheduled sometime between May 3 and May 7.

“After reviewing our recent progress, it was clear that we needed more time to finish hardware-in-the-loop testing and properly review and follow up on all data,” SpaceX spokeswoman Kirstin Brost Grantham wrote in an email. “While it is still possible that we could launch on May 3rd, it would be wise to add a few more days of margin in case things take longer than expected. As a result, our launch is likely to be pushed back by one week, pending coordination with NASA.”

The Space Launch System is a threat to JSC, Texas jobs

9:23 am

An op-ed in Houston: “The Space Launch System is a threat to JSC, Texas jobs.”

It appears that even some NASA employees are beginning to see the madness of spending billions on a launch system that will likely only fly one mission almost a decade from now. And it will seem even more mad to more people should Dragon and Cygnus prove successful in the coming year.

To put it bluntly, the long term politics are very much hostile to SLS. It is going to die, if only because the federal government is bankrupt and can’t afford it. I just wish our elected officials had the brains to realize this now rather than three years down the road.

New simulations suggest that the magnitude of tsunamis predicted to hit Japan have previously been underestimated.

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.

Coming and going

9:10 am

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.

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.”

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.
