ISS aboveMany of you reading this have probably spotted the International Space Station from below. If you haven’t, check out this website for instructions and times to look (https://spotthestation.nasa.gov). But, how many of you have ever seen the ISS from above?I actually think it’s safe to say the answer is zero, since the last time a human was farther out than the space station’s orbit was the last Hubble Space Telescope servicing mission. Hopefully this sequence of shots fills some of that gap.On June 19, the Landsat 8 spacecraft passed over the space station while taking its usual sequence of Earth monitoring photos. It captured this sequence, visible here in gif form.As the Landsat satellite collects images, it switches filters to observe the planet at different light wavelengths. These different filters let scientists see different things, as some are sensitive to vegetation, rocky exposures, clouds, etc. As it takes a bit of time for the filter to switch, the space station literally moves from frame to frame, allowing a gif to be constructed showing its path.-JBBGif credit: NASA/USGS/Landsathttp://landsat.gsfc.nasa.gov/?p=12600 -- source link
