This illustration shows NASA’s Cassini spacecraft diving through the plume of Saturn’s moon Enceladus, in 2015. Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. via NASA http://ift.tt/2pyf5di

NASA scientists are releasing new global maps of Earth at night, providing the clearest yet composite view of the patterns of human settlement across our planet. This composite image, one of three new full-hemisphere views, provides a view of the Americas at night. via NASA http://ift.tt/2o6PerJ

Through NASA’s Space Technology Research Fellowship (NSTRF) program, a fresh approach to designing and manufacturing heat-thwarting thermal protection systems – or heatshields – for spacecraft is being developed and tested, offering the promise of fabricating larger tile sizes while reducing labor, cost and waste. via NASA http://ift.tt/2p2cknX

A horse drawn caisson carries former astronaut and U.S. Senator John Glenn to his final resting place during the interment ceremony at Arlington National Cemetery on Thursday, April 6, 2017, in Virginia. Glenn was the first American to orbit Earth on Feb. 20, 1962, in a five-hour flight aboard the Friendship 7 spacecraft. via NASA http://ift.tt/2oOtUsT

This illustration shows NASA’s Cassini spacecraft about to make one of its dives between Saturn and its innermost rings as part of the mission’s grand finale. Cassini will make 22 orbits that swoop between the rings and the planet before ending its mission on Sept. 15, 2017, with a final plunge into Saturn. via NASA http://ift.tt/2oCWUXh

Expedition 50 Flight Engineer Thomas Pesquet of the European Space Agency (ESA) photographed brightly glowing auroras from his vantage point aboard the International Space Station on March 27, 2017. Pesquet wrote, “The view at night recently has been simply magnificent: few clouds, intense auroras. I can’t look away from the windows.” via NASA http://ift.tt/2nYJfZv

Although only a sliver of Saturn’s sunlit face is visible in this view, the mighty gas giant planet still dominates the view. via NASA http://ift.tt/2oug9lG

Dr. Nancy Grace Roman is shown with a model of the Orbiting Solar Observatory (OSO) in 1962. She was the first Chief of Astronomy in the Office of Space Science at NASA Headquarters and the first woman to hold an executive position at NASA. She had oversight for the planning and development of programs including the Hubble Space Telescope. via NASA http://ift.tt/2ohUxc9
