A new map of Mars' gravity is the most detailed to date, providing a revealing glimpse into the planet's hidden interior. The map was derived using Doppler and range tracking data collected by NASA's Deep Space Network from three NASA spacecraft in orbit around Mars: Mars Global Surveyor, Mars Odyssey, and the Mars Reconnaissance Orbiter.

This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface.
On March 16, 1966, command pilot Neil Armstrong and pilot David Scott successfully docked their Gemini VIII spacecraft with the Agena target vehicle, the first-ever linking of two spacecraft together in Earth orbit. This crucial spaceflight technology milestone would prove vital to the success of future moon landing missions.
The remotely controlled Sally Ride EarthKAM aboard the International Space Station snapped this striking photograph of South Africa on Feb. 9, 2016. The EarthKAM program allows students to request photographs of specific Earth features, which are taken by a special camera mounted on the space station when it passes over those features.
NASA's Cassini spacecraft captured this view of Saturn's moon Enceladus that shows wrinkled plains that are remarkably youthful in appearance, being generally free of large impact craters.
