Deep-Space Landslide Yields an Avalanche of Insight on Asteroid Structure

By studying a landslide on the asteroid Bennu, a team of scientists led by Johns Hopkins APL’s Mark Perry has gained new insight into the surface strength — or weakness — of so-called rubble-pile asteroids, the loose collections of smaller rocks and dust held together by their own gravity.

CRISM Team Closing Operations with New Global Map of Mars

In a last hurrah for an imager entering its final months of operation, the CRISM team at Johns Hopkins APL is releasing a new near-global map of Mars produced by the instrument. The first of what will be thousands of pieces colored to convey the mineral composition of the Martian surface were released on Wednesday.

NASA’s DART Captures One of Night Sky’s Brightest Stars

On its journey to collide with an asteroid in the world’s first planetary defense test mission, NASA’s DART captured images of the nearby and very bright star Vega in a test of how light scatters off of the spacecraft’s camera DRACO and other internal parts.

Why Phaethon Turned Blue — and How Other Small Sun-Diving Bodies Might, Too

Asteroid Phaethon’s bizarrely blue color has long been a planetary science puzzle, but a study co-authored by Johns Hopkins APL’s Carey Lisse may have finally untangled the chemical process that gave the asteroid its azure hue.

Johns Hopkins APL Delivers Propulsion Module for NASA Mission to Europa

After years of design and construction, two cross-country trips and thousands of hours of labor, APL has delivered NASA's Europa Clipper propulsion module — the spacecraft's “workhorse" — and its radio frequency module to the Jet Propulsion Laboratory for integration with the remainder of the spacecraft.
