Astronaut Thomas Pesquet of the European Space Agency captured this photograph from the International Space Station on Nov. 25, 2016, and shared it on social media, writing, “Sunrises. We experience 16 sunrises every 24 hours on the International Space Station as it takes us 90 minutes to do a complete orbit of our planet flying at 28,800 km/h.” via NASA http://ift.tt/2htfFoS

On November 1, 2016, NASA’s Aqua satellite passed over Indonesia, allowing the Moderate Resolution Imaging Spectroradiometer (MODIS) on board to capture a stunning true-color image of oceanic nonlinear internal solitary waves from the Lombok Strait. via NASA http://ift.tt/2gTsLOY

Middle school students programmed a camera aboard the International Space Station — the Sally Ride EarthKAM — to photograph this portion of the Sahara desert in western Libya on October 3, 2016. The Expedition 50 crew set up the EarthKAM gear in the Harmony module’s Earth-facing hatch window, to allow students to photograph targets on Earth. via NASA http://ift.tt/2gz3WVF

What looks like a teleporter from science fiction being draped over NASA’s James Webb Space Telescope, is actually a “clean tent.” The clean tent protects Webb from dust and dirt when engineers at NASA’s Goddard Space Flight Center transport the telescope out of the relatively dust-free cleanroom and into the vibration and acoustics testing areas. via NASA http://ift.tt/2gxOxoO

An astronaut aboard the International Space Station photographed a sunset that looks like a vast sheet of flame. With Earth’s surface already in darkness, the setting sun, the cloud masses, and the sideways viewing angle make a powerful image of the kind that astronauts use to commemorate their flights. via NASA http://ift.tt/2fMNDXg
