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.
Beatboxer Tom Thum had ENT doctor and laryngeal surgeon Dr Matthew Broadhurst shine an endoscopic camera down his throat while beatboxing: “I wanted to find out how my larynx functioned when beatboxing compared to how it functions normally with speech, and whether or not there were any abnormalities in my laryngeal anatomy. I also had […]
Gastric bypass surgery is remarkably effective at promoting weight-loss (it cuts the long-term risk of early death from morbid obesity by 40%), and it’s long been presumed that the major action by which it worked was that, by bypassing the parts of the gut where most food absorbtion takes place, it limited the calories that […]
Timothy writes, “Diego Gómez is a Colombian conservation biologist. When he was a college student, he shared a single research paper online so that others could read and learn from it, just as he did. Diego was criminally prosecuted for copyright infringement, and faced up to 8 years in prison.”
While some people still maintain that everything in Apple’s walled garden “just works” and is immune to the rampant malware of the Windows world, the reality is different. The Mac’s growing market share has made it a much more viable target for malicious actors, and its built-in tools aren’t always enough to fix things. Drive […]
