NASA’s OSIRIS-REx spacecraft finds particles flying off asteroid Bennu

March 19, 2019

The early months of NASA’s OSIRIS-REx mission’s exploration of asteroid Bennu have revealed big surprises, scientists said Tuesday, including plumes of particles streaming away from the asteroid, sometimes with enough velocity for rocks to break out of Bennu’s tenuous gravitational grip and escape into space.

Hubble’s premier camera resumes observations

January 25, 2019

The most-used instrument on the orbiting Hubble Space Telescope is back in business after engineers on the ground determined a fault that halted the camera’s science observations earlier this month was caused by erroneous telemetry data, and was not a symptom of a hardware failure as initially suspected.

Controllers troubleshoot problem with Hubble camera

January 10, 2019

The partial shutdown of the U.S. government could complicate efforts to troubleshoot a suspected hardware problem with the Hubble Space Telescope’s premier science instrument, but officials are optimistic the camera will eventually be restored to operations, the head of the observatory’s science operations team said Wednesday.

Engineers say goodbye to society-changing Delta 2 rocket

September 14, 2018

When the first Delta 2 rocket took off on Valentine’s Day 1989, ideas like navigating by smartphone and driving robots on Mars were science fiction. More than 150 launches over the last 30 years helped change all that.

Live coverage: Final Delta 2 rocket launches from California

September 14, 2018

The final flight of a Delta 2 rocket, a mainstay of the U.S. launch industry for nearly 30 years, began at 6:02 a.m. PDT (9:02 a.m. EDT; 1302 GMT) from Vandenberg Air Force Base in California with NASA’s ICESat 2 Earth science satellite.

Scientists eager to renew global ice measurements with ICESat 2 mission

September 14, 2018

The satellite awaiting launch early Saturday from California aboard the final flight of the venerable Delta 2 rocket should allow scientists to more precisely track changes in our planet’s ice sheets, using six green laser beams to chart the height and slope of polar ice and glaciers, providing a key input into climate change research.
