NASA awards a key piece of ISS management to Florida, not Houston.
The story reports that politics were not involved, but I am suspicious. Since all ISS management and operations come out of Houston, why send some of that management to Florida?
The second ARTEMIS space probe will enter lunar orbit on Sunday.
“With two spacecraft orbiting in opposite directions, we can acquire a full 3-D view of the structure of the magnetic fields near the moon and on the lunar surface,” said Vassilis Angelopoulos, principal investigator for the THEMIS and ARTEMIS missions and a professor of space physics at UCLA. “ARTEMIS will be doing totally new science, as well as reusing existing spacecraft to save a lot of taxpayer money.”
White dwarf stars in a dance of death.
[The binary pair of] white dwarfs are so near they make a complete orbit in just 13 minutes, but they are gradually slipping closer together. About 900,000 years from now – a blink of an eye in astronomical time – they will merge and possibly explode as a supernova. By watching the stars converge, scientists will test both Einstein’s general theory of relativity and the origin of some peculiar supernovae.
The two white dwarfs are circling at a bracing speed of 370 miles per second (600 km/s), or 180 times faster than the fastest jet on Earth. “I nearly fell out of my chair at the telescope when I saw one star change its speed by a staggering 750 miles per second in just a few minutes,” said Smithsonian astronomer Warren Brown, lead author of the paper reporting the find.
The brighter white dwarf contains about a quarter of the Sun’s mass compacted into a Neptune-sized ball, while its companion has more than half the mass of the Sun and is Earth-sized. A penny made of this white dwarf’s material would weigh about 1,000 pounds on Earth. Their mutual gravitational pull is so strong that it deforms the lower-mass star by three percent. If the Earth bulged by the same amount, we would have tides 120 miles high. [emphasis mine]
An evening pause: Jailbreak!
I’ve posted earlier about Dawn’s approach to Vesta. However, in looking at the images from Dawn, it dawned on me recently that they seems more fuzzy for what you’d normally expect from a space probe. I am now wondering if there is something fundamentally wrong with Dawn’s camera, causing its images to be slightly out of focus.
SpaceX is about to break ground on launchpad and hanger for Falcon Heavy.
On Monday China successfully launched its second data relay satellite, expanding its space communications network in preparation for before its first unmanned rendezvous and docking attempt later this year.
New evidence bolsters the asteroid impact theory of dinosaur extinction 65 million years ago.
I am sure you all thought the cause of the dinosaurs’ extinction — an asteroid impact on the Yucatan peninsula — was settled science. Wrong!

An evening pause: What some people really think about the TSA:
Arab journalists demand the blacklisting of a Israeli journalist at a journalism conference in Qatar, merely because she is from Israel.
Starvation, scurvy, or lead poisoning? A skeleton from the 1848 Franklin Expedition to the Arctic may tell scientists what caused the expedition’s destruction.
The House spending panel today proposed cutting the budget of the White House Office of Science and Technology Policy (OSTP) office, run by John Holdren, by 55%.
“OSTP has chosen to disregard a strong and unambiguous legislative prohibition on bilateral engagement with China or Chinese-owned companies,” says language accompanying the 2012 bill, to be voted on tomorrow by the full appropriations committee. “OSTP’s behavior demonstrates a lack of respect for the policy and oversight roles of the Congress.”
I think the Obama administration is about to discover that ignoring the law as passed by Congress can have bad consequences.
