Whatever organic chemicals may be produced on Mars or delivered to Mars face several possible modes of being transformed or destroyed. Organic chemicals are molecular building block of life, although they can be made without the presence of life. Whether or not organic chemicals are produced by processes on Mars, some are delivered to the planet aboard meteorites and dust from asteroids and comets.
Only 15 minutes after its closest approach to Pluto on July 14, 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon. The smooth expanse of the informally named icy plain Sputnik Planum (right) is flanked on the left by rugged mountains up to 11,000 feet (3,500 meters) high, including the informally named Norgay Montes in the foreground and Hillary Montes on the…

Long ago, in the largest canyon system in our solar system, vibrations from "marsquakes" shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on new NASA images.
