The last remant of a supernova

9:30 am

Time for some astronomical sightseeing! This image, produced from data taken by both the Hubble Space Telescope and the Chandra X-ray Observatory, shows what astronomers call a supernova remnant. The bubble, located in the Large Magellanic Cloud 160 thousand light years away, is thought to be 23 light years across and expanding about 11 million miles per hour. It is thought that the supernova itself took place around 1600. That we have no record of it is probably because it was only visible in the southern hemisphere, where few records of such events were being kept at that time. More here, including the image using only Hubble data as well as a video animation that is quite stunning.

Orbital Sciences and Virgin Galactic team up to propose orbital craft

10:50 pm

Orbital Sciences and Virgin Galactic have teamed up to propose a four person reusable orbital spacecraft to ferry crews to ISS. Key quote:

The spacecraft, designed to launch atop an Atlas 5 rocket and dock with the international space station, could be ready for test flights as early as 2014. The remotely piloted spacecraft would be able to carry four passengers initially, including three astronauts and one paying ticketholder, though based on market demand the number of private rides aboard the vehicle could grow to two, with four astronaut seats available, sources said. In the works at Orbital for the past year, the reusable spacecraft would be built using existing materials and technologies, employ standard hypergolic propellants and rely on a pusher escape system in the event of a launch mishap, sources said. [emphasis mine]

Note their insistence that they be allowed to fly tourists. This is a major change from how NASA has operated in the past, as a Soviet-style government agency hostile to commercial profits.

Correction: Clark Lindsey notes that the Orbital press release makes no mention of Virgin Galactic, as reported above.

Facing the facts

8:03 pm

An evening pause: The reaction of the ship captain in the opening section of this clip from the movie A Night to Remember (1958) exemplifies better than anything I have ever seen the clarity and courage of an open mind, willing to face new facts instantly and to react correctly, even if by doing so you risk failure and disgrace.

If only our leaders today had as much courage.

NASA Picks New Chief Scientist

4:57 pm

Today’s announcement by the Obama administration of their choice for NASA’s new chief scientist, Waleed Abdalati, reveals once again how much climate research guides their thinking, not space exploration. Key quote:

His research has focused on the study of polar ice cover using satellite and airborne instruments. He has led or participated in nine field and airborne campaigns in the Arctic and the Antarctic.

This is not a criticism of Dr. Abdalati. His research interests, however, make very clear where the Obama administration really wants NASA to look: down at the Earth instead of up beyond Earth orbit.
