Engineers say goodbye to society-changing Delta 2 rocket
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.
VideoLive coverage: Final Delta 2 rocket launches from California
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
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.
Station commander flatly denies any crew involvement in Soyuz leak
The head of the Russian space agency caused a stir last week when he said a hole drilled through the side of a Soyuz ferry ship docked to the International Space Station was the result of a deliberate act, "either on Earth or in space." Station commander Drew Feustel said Tuesday it most certainly did not happen in orbit.
Station crew faces busy schedule as commercial crew schedule ramps up
An impromptu repair job Thursday appears to have stopped a leak in a Russian Soyuz spacecraft docked to the International Space Station, and the crew was back on its normal schedule Friday carrying out research and making preparations for the arrival of a Japanese cargo ship next month.
Two NASA probes catch first glimpses of primordial targets
Two NASA spacecraft -- the OSIRIS-REx asteroid sample return mission and the New Horizons probe at the edge of the solar system -- have captured their first looks at their targets as they approach a pair of primordial relics for the first time.
Installation of ice-measuring satellite caps assembly of last Delta 2 rocket
NASA's ICESat 2 satellite has been bolted atop a United Launch Alliance Delta 2 rocket at Vandenberg Air Force Base in California as ground teams prepare for the final liftoff of the workhorse launcher Sept. 15.
Engineers still hopeful Mars rover will wake up after dust storm
Flight controllers have not heard from NASA's Opportunity Mars rover since June 10 when an increasingly severe global dust storm blocked out the sun, preventing its solar arrays from recharging the robot's batteries. But the dust storm is finally abating and engineers are hopeful the long-lived rover will wake up and phone home in the next few weeks.
Photos: Final Delta 2 rocket assembled for launch in California
The step-by-step stacking of United Launch Alliance's final Delta 2 rocket was completed in June at Vandenberg Air Force Base in California for liftoff Sept. 15 with an Earth science satellite for NASA.
Tanking test marks resumption of Delta 2 rocket’s final launch campaign
A team of United Launch Alliance and NASA engineers worked through Delta 2 launch day fueling procedures during a simulated countdown Wednesday for what should be the second-to-last time before the venerable rocket's final liftoff next month from California's Central Coast.
