SpaceX suspends production of its Falcon 1 rocket
SpaceX suspends production of its Falcon 1 rocket.
As much as I am a fan of Elon Musk and SpaceX, and though I realize that they have been focusing on getting Falcon 9 and Dragon off the ground — the payoff there is greater and a failure of Falcon 1 during this time could be very politically painful — this action contradicts SpaceX’s years of claims that they had a slew of signed contracts to launch Falcon 1.
I will be attending Elon Musk’s luncheon speech today at the National Press Club, and hope to ask him about this and other things.

The coming blindness of astronomy
The European Southern Observatory today released this infrared image today of what astronomers have named the Fried Egg Nebula. Taken by the Very Large Telescope in Chile, the picture shows the concentric dust shells surrounding a post-red supergiant star, thought to be transitioning to the next stage of stellar evolution called a yellow hypergiant. As the press release explains,
The monster star, known to astronomers as IRAS 17163-3907, has a diameter about a thousand times bigger than our Sun. At a distance of about 13 000 light-years from Earth, it is the closest yellow hypergiant found to date and new observations show it shines some 500 000 times more brightly than the Sun. . . . If the Fried Egg Nebula were placed in the centre of the Solar System the Earth would lie deep within the star itself and the planet Jupiter would be orbiting just above its surface. The much larger surrounding nebula would engulf all the planets and dwarf planets and even some of the comets that orbit far beyond the orbit of Neptune. The outer shell has a radius of 10 000 times the distance from the Earth to the Sun.
Yellow hypergiants are in an extremely active phase of their evolution, undergoing a series of explosive events — this star has ejected four times the mass of the Sun in just a few hundred years. The material flung out during these bursts has formed the extensive double shell of the nebula, which is made of dust rich in silicates and mixed with gas.
According to the science paper [pdf] describing this research, the stage of yellow hypergiants is a preliminary to the star evolving into a luminous blue variable, of which Eta Carinae is the most famous. In this next stage a star is thought to have a good chance of going supernova.
Though this image is truely spectacular, taken by a ground-based telescope of a star 13,000 light years away, what I find most significant about this image is its fuzziness. It reminds me of the kind of images astronomers and the public routinely accepted as the best possible, before the launch of the Hubble Space Telescope.

Orbital Sciences has launch success
Orbital Sciences has a launch success, putting an Air Force reconnaissance satellite into orbit from the Kodiak Launch Complex in Alaska.
For Orbital, this success cleans off some of the stain left on the company from the recent launch failures of its Taurus 1 rocket. What would leave the company stainless, however, will be a successful first launch of its new Taurus 2 rocket, needed to carry its Cygnus capsule to ISS and scheduled for late this year.

UARS falls in ocean
UARS has come to Earth, re-entering the atmosphere at 11:23 pm (Eastern) last night over the Pacific Ocean.

Another UARS update
Aerospace Corporation has further refined its prediction for the deorbit of UARS. The window now goes from 11 pm to 3 am tonight, with the only land areas at risk being Canada, Africa, and Australia.
NASA now says re-entry will be between 11:45 and 12:45 am (Eastern), putting only Canada and Africa in the satellite’s path.

UARS crash updated
The most recent prediction now says that the UARS satellite will come down tonight between 9 pm and 3 am Eastern time, during one of four orbits, all of which pass over North America, Europe, and Africa. One orbit also passes over Australia.

Update on UARS reentry
The crash time of the UARS climate satellite has now been updated to a window lasting from 6 pm (Eastern) to 4 am (Eastern) tonight.
According to the map at the link, the U.S., Europe, Africa, and Middle East are all potential crash sites.

A second large satellite will rain debris down in October
Even if UARS misses you today, don’t relax! A second large satellite, the 2.4 ton ROSAT X-Ray space telescope, is going to rain debris down late in October or early November.
On its ROSAT website, DLR estimates that “up to 30 individual debris items with a total mass of up to 1.6 tonnes might reach the surface of the Earth. The X-ray optical system, with its mirrors and a mechanical support structure made of carbon-fibre reinforced composite – or at least a part of it – could be the heaviest single component to reach the ground.”

Blurred vision a risk for astronauts who spend months in space
Blurred vision is now considered a serious risk for astronauts who spend months in space.
According to one NASA survey of about 300 astronauts, nearly 30 percent of those who have flown on space shuttle missions – which usually lasted two weeks — and 60 percent who’ve completed six-month shifts aboard the station reported a gradual blurring of eyesight.
This story is a followup on information contained in an earlier National Academies report on astronaut staffing.

China has resumed rocket launches after an August failure, putting a communications satellite into orbit.
This bodes well for the pending launch of the country’s first space station module, Tiangong 1.

Another look at the cost of building NASA’s heavy lift rocket
Clark Lindsey takes another look at the cost for building the Congressionally-mandated heavy lift rocket, what NASA calls the Space Launch System and I call the program-formerly-called-Constellation. Key quote:
Finally, I’ll point out that there was certainly nothing on Wednesday that refuted the findings in the Booz Allen study that NASA’s estimates beyond the 3-5 year time frame are fraught with great uncertainty. Hutchison and Nelson claimed last week that since the near term estimates were reliable, there’s no reason to delay getting the program underway. That’s the sort of good governance that explains why programs often explode “unexpectedly” in cost after 3-5 years…
In other words, this is what government insiders call a “buy-in.” Offer low-ball budget numbers to get the project off the ground, then when the project is partly finished and the much higher real costs become evident, Congress will be forced to pay for it. Not only has this been routine practice in Washington for decades, I can instantly cite two projects that prove it:
