On Dec. 24, 2013, NASA astronaut Mike Hopkins, Expedition 38 Flight Engineer, participates in the second of two U.S. spacewalks, spread over a four-day period, which were designed to allow the crew to change out a faulty water pump on the exterior of the Earth-orbiting International Space Station. He was joined on both spacewalks by NASA astronaut Rick Mastracchio, whose image shows up in Hopkins' helmet visor.
Basking in sunlight. The whole northern region of Saturn is bathed in sunlight in this view from late 2016 from our Cassini spacecraft. The hexagon-shaped jet-stream is fully illuminated here. Mission experts on Saturn's atmosphere are taking advantage of the season and Cassini’s favorable viewing geometry to study this and other weather patterns as Saturn's northern hemisphere approaches Summer solstice.
This image, taken by NASA's Near Earth Asteroid Rendezvous mission in 2000, shows a close-up view of Eros, an asteroid with an orbit that takes it somewhat close to Earth. NASA's Spitzer Space Telescope observed Eros and dozens of other near-Earth asteroids.
