How to get rid of a satellite after its retirement

more »
Researchers have developed a new method to eliminate artificial satellites in Highly Elliptical Orbits when they finish their mission. The methodology, which allows for a reduction of both cost and risk, has been tested with the European Space Agency INTEGRAL mission, which will re-enter into the Earth's atmosphere in order to disintegrate in 2029.

New report: Solyndra executives lied to DOE officials to get loans

Science Focus

original post »

In a few short years, Solyndra went from a promising US-based manufacturer of high-tech solar panels to a bankrupt political football. The company received substantial loans from the Department of Energy during the financial stimulus that followed Obama's election. But shortly afterwards, the company went bankrupt amidst allegations that political pressure had played a role in ensuring that it received these loans.

Now, the DOE's inspector general has weighed in with a report describing its investigation into Solyndra's loans. The report suggests that, while political pressure may have made matters worse, lies by the company's executives were central to the loan failures.

The DOE's loan guarantees program is meant to foster riskier domestic energy programs (such as nuclear power plants) that would have difficulty securing financing otherwise. While they're expected to fail on occasion, the DOE is expected to do due diligence and put its money toward viable companies.

Keyhole Nebula and Digitus Impudicus Square Sticker

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: kndigimp, envelope sealers, galaxies and stars, keyhole nebula, carina nebula, massive stars, hubble space telescope, digitus impudicus, complex structure

Galaxies, Stars and Nebulae series Details of a mysterious, complex structure within the Carina Nebula (NGC 3372) are revealed by this image of the 'Keyhole Nebula, ' obtained with the Hubble Space Telescope. The picture is a montage assembled from four different April 1999 telescope pointings with Hubble's Wide Field Planetary Camera 2, which used six different colour filters. The picture is dominated by a large, approximately circular feature, which is part of the Keyhole Nebula, named in the 19th century by Sir John Herschel. This region, about 8000 light-years from Earth, is located adjacent to the famous explosive variable star Eta Carinae, which lies just outside the field of view toward the upper right. The Carina Nebula also contains several other stars that are among the hottest and most massive known, each about 10 times as hot, and 100 times as massive, as our Sun.

Holographic lens printing method could allow printing of telescope lenses in space

more »
(Phys.org)—Researchers have developed a method for printing optical holographic lenses that could greatly simplify their fabrication. Because the method can be performed quickly and easily, it could potentially be used by astronauts to print lenses while in space for holographic lens telescopes.

Milky Way with Airglow Australis

more »
After sunset on September 1, an exceptionally intense, reddish airglow flooded this Chilean winter night skyscape. Above a sea of clouds and flanking the celestial Milky Way, the airglow seems to ripple and flow across the northern horizon in atmospheric waves. Originating at an altitude similar to aurorae, the luminous airglow is instead due to chemiluminescence, the production of light through chemical excitation. Commonly captured with a greenish tinge by sensitive digital cameras, this reddish airglow emission is from OH molecules and oxygen atoms at extremely low densities and has often been present in southern hemisphere nights during the last few years. On this night it was visible to the eye, but seen without color. Antares and the central Milky Way lie near the top, with bright star Arcturus at left. Straddling the Milky Way close to the horizon are Vega, Deneb, and Altair, known in northern nights as the stars of the Summer Triangle.
