Little Moon Io helps Jupiter Accelerate Charged Particles to Incredible Speeds
Data from the APL-built JEDI instrument on NASA’s Juno spacecraft reveal Jupiter’s moon Io accelerates protons to millions of miles per hour through an invisible link.
DART Mission Heats Up, Enters Environmental Testing
A months-long integration and testing phase culminated recently with a successful review and the start of space-environment testing for NASA's first planetary defense mission, the APL-led Double Asteroid Redirection Test (DART).
Parker Solar Probe Captures Planetary Portrait
The APL-built Parker Solar Probe was wheeling around the Sun last summer when it spied six planets — Mercury, Venus, Earth, Mars, Jupiter and Saturn — in its camera's field of view.
Study reveals MESSENGER watched a Meteoroid strike Mercury
The Johns Hopkins APL-led MESSENGER spacecraft watched a meteoroid crash into Mercury, a recent study shows. It's the first impact ever observed on the surface of another planet.
DART Team Takes a Last Look at Asteroid Target Before Launch
DART’s investigation team has kicked off the mission’s final prelaunch observation campaign on the ground, using powerful telescopes located around the world to get a glimpse of the asteroid system that DART will encounter this year.
Johns Hopkins APL team lauded for Lunar Technology Leadership
The team that stood up an organization to help advance lunar surface technology development will receive a NASA Headquarters 2020 Honor Award.
Johns Hopkins APL Space Weather Mission Selected by NASA
NASA has given APL the nod to develop the Electrojet Zeeman Imaging Explorer (EZIE), a mission to explore electric currents in Earth’s atmosphere that link the aurora to our planet’s magnetosphere.
New Exoplanet Research Method could uncover Thousands of Habitable Worlds
A new method could be groundbreaking for exoplanet research, opening up a vast population of potentially habitable planets that has been inaccessible to scientific study.
MEGANE Instrument Test Model Goes to Japan for Physical Tests and Design Review
The team building MEGANE for Japan’s MMX mission recently shipped a test model to determine how well the instrument fits in the spacecraft design.
Surer Signs of Life
New technology could help us find some of the strongest evidence of life elsewhere in the solar system, from purifying samples to even sequencing DNA from another world.
