That little smeary line in the center isn't a camera defect, it's the Lunar Atmosphere and Dust Environment Explorer (LADEE), as photographed by the Lunar Reconnaissance Orbiter (LRO), which is orbiting the Moon about 5.5 miles above LADEE's orbit. This was a pretty difficult shot to take, given the fact that both spacecraft are moving at speeds of 3600 mph and their perpendicular orbits only briefly intersect. The LRO camera team has a detailed explanation of how they made this shot work:
Since LROC is a pushbroom imager, it builds up an image one line at a time, thus catching a target as small and fast as LADEE is tricky! ... LADEE passed directly beneath the LRO orbit plane a few seconds before LRO crossed the LADEE orbit plane, meaning a straight down LROC image would have just missed LADEE. Now is where the careful planning came into play. The LADEE and LRO teams worked out the solution: simply have LRO roll 34° to the west so the LROC detector (one line) would be in the right place as LADEE passed beneath.
NASA’s Langley Research Center in Hampton, Virginia turns 100 this year. In celebration, the space agency produced this short documentary and enlisted Captain Kirk himself, William Shatner, to narrate. Here are just a few highlights from NASA Langley’s incredible history: • In times of peace and war, NASA Langley helped to create a better airplane, […]
Rio Celeste is a gorgeous Costa Rican river with a length that’s famous for its unusual turquoise waters. After decades of guessing, scientists finally determined the cause was aluminosilicate:
AntsCanada (previously) has an overpopulation problem in his yellow crazy ant colony, so he added two kinds of carnivorous pitcher plants. The resulting relationship between ant versus plant turned out to be quite fascinating.

Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
