NOAA Selects Johns Hopkins APL’s George Ho for Space Weather Advisory Group

George Ho, a space and planetary physicist at Johns Hopkins APL, was tapped by NOAA to serve on its new Space Weather Advisory Group. The board will counsel the federal government on mitigating and responding to the deleterious effects of space weather on the nation’s space assets and humanity.

Psyche’s Gamma Ray and Neutron Detection Instrument Arrives in California for Spacecraft Installation

After five years of developing and testing a complex gamma-ray and neutron detection instrument for NASA’s Psyche mission, the world’s first mission to study a potentially metal-rich asteroid, the APL Psyche team can finally take a breather. The instrument safely arrived at the Jet Propulsion Laboratory in California on Aug. 2.

The Van Allen Probes Transformed Everything We Know About Earth’s Radiation Belts. What’s Next?

Nine years after NASA’s Van Allen Probes launched into space to study the radiation environment around Earth, APL gathered scientists and satellite operators from around the world to discuss the future of space weather research, including ways to protect astronauts and satellites. Here are their four big takeaways.

DART Gets Its Wings: Spacecraft Integrated with Innovative Solar Array Technology and Camera

The DART spacecraft’s recently installed Roll-Out Solar Arrays and DRACO imager are two critical technologies that will enable the spacecraft to navigate through space and effectively reach the Didymos system as part of a carefully planned asteroid deflection experiment.

SMART Nav: Giving Spacecraft the Power to Guide Themselves

NASA’s DART mission will be the first-ever to test a way to protect Earth from an asteroid strike. But to ensure DART hits its harmless test target, scientists and engineers at Johns Hopkins APL developed a guidance system unlike anything used on spacecraft before — a system that can direct a spacecraft entirely on its own without any human intervention.
