LPL Spotlight Stories

A vast hotspot of intense volcanism underneath the dark, blotchy “face” of the moon known as Oceanis Procellarum (red area on right) resulted in less density there than in other parts of the moon. To restore balance, the moon’s axis shifted by six degrees. Traces of water ice deposits near the poles outline the movement from the location of the ancient (blue) to the present pole (teal).

Mars as it may have looked like billions of years ago: Vast plumes of ash and water vapor billow into the atmosphere from the Tharsis region (on the right), a massive bulge of volcanic activity that created the tallest mountains in the solar system. Meanwhile, an icy ring of precipitation carves out valleys and canyons around a ring just south of the Martian equator. (Image: Didier Florentz)

The actual mechanism causing asteroids to disrupt is still unknown but some obvious scenarios such as tidal forces caused by the Sun and direct sublimation of silicates have been ruled out. One of the remaining scenarios is that volatiles inside the asteroid sublimate at moderate temperatures and create enough pressure to blow up the body. A similar process on a smaller scale called spalling can also break up surface rocks. Credit: Lauri Voutilainen

With its suite of science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras. Juno's principal goal is to understand the origin and evolution of Jupiter. (Artist's concept: NASA/JPL)

This image of the spacecraft was captured by StowCam when OSIRIS-REx was 3.9 million miles away from Earth. Featured prominently in the image is the Sample Return Capsule, which will provide the asteroid sample’s ride back to Earth in 2023. No stars are visible because of the bright illumination provided by the sun. (Image: NASA)
