NASA Science Briefing: Comet Siding Spring at Mars

A new analysis of gullies carved into Martian impact craters suggests the Red Planet has undergone several ice ages in the last several million years. The driver of these climate swings is likely the planet’s wobbly axis tilt.

NASA’s New Horizons scientists made this false colour image of Pluto using a technique called principal component analysis to highlight the many subtle colour differences between Pluto’s distinct regions. The image data were collected by the spacecraft’s Ralph/MVIC colour camera on 14 July at 11:11 UTC, from a range of 22,000 miles (35,000 kilometres).

NASA’s Lunar Reconnaissance Orbiter will try to locate India’s Vikram lander on the moon during a flyover of the landing site Tuesday. Indian space officials said they found the disabled spacecraft on the moon using the country’s own Chandrayaan 2 orbiter, but declined to release any images.
