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.

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.
