DART Tests Autonomous Navigation System Using Jupiter and Europa

After capturing images of one of the brightest stars in Earth’s night sky, NASA’s Double Asteroid Redirection Test (DART) spacecraft turned its camera toward another eye-catching spectacle: Jupiter and its four largest moons.

DART’s Small Satellite Companion Takes Flight Ahead of Impact

The small satellite companion aboard NASA’s Double Asteroid Redirection Test (DART) has successfully separated from the main spacecraft, popping out of its spring-loaded box to capture valuable information about DART’s impact into an asteroid that will inform future planetary defense efforts.

DART Sets Sights on Asteroid Target

NASA’s Double Asteroid Redirection Test (DART) spacecraft recently got its first look at Didymos, the double-asteroid system that includes its target, Dimorphos.

DART Team Confirms Orbit of Target Asteroid

Using some of the world’s most powerful telescopes, the Double Asteroid Redirection Test (DART) investigation team confirmed the orbit of Dimorphos around its parent asteroid, Didymos, and its expected location when the DART spacecraft impacts the moonlet next month.

Webb Telescope Spots Carbon Dioxide in Exoplanet Atmosphere for First Time

A new study using NASA’s James Webb Space Telescope and that involved researchers from Johns Hopkins APL reports the detection of carbon dioxide in the atmosphere of a planet from another planetary system. The discovery underscores Webb’s impressive capabilities and promises exciting results when researchers later peer at smaller rocky planets across the galaxy.

EZIE Mission Jets into Next Development Stage

NASA has given Johns Hopkins APL the green light to begin detailed designs on the Electrojet Zeeman Imaging Explorer (EZIE) — a SmallSat mission to characterize the electric currents that link Earth’s aurora to the planet’s magnetosphere.

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.
