Engineers say goodbye to society-changing Delta 2 rocket

September 14, 2018 Stephen Clark

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 Stephen Clark

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 Stephen Clark

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

September 11, 2018 William Harwood

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.

Dwindling fuel levels and a balky thruster can’t keep Kepler down

September 7, 2018 Stephen Clark

After downloading science data and bypassing a balky thruster, NASA’s Kepler mission has resumed its search for planets around other stars after a two-month pause in observations, but engineers expect the spacecraft to soon run out of fuel.

The towering structure to be used for liftoffs of NASA’s Space Launch System rolled from a construction site to launch pad 39B at the Kennedy Space Center in Florida this week, arriving at the seaside complex Friday for a week of fit checks.

Station crew faces busy schedule as commercial crew schedule ramps up

August 31, 2018 William Harwood

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

August 29, 2018 Stephen Clark

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

August 28, 2018 Stephen Clark

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.

SLS mobile launch platform to go on the move this week

August 27, 2018 Stephen Clark

The mobile platform intended to carry NASA’s Space Launch System will trek to the mega-rocket’s launch pad at the Kennedy Space Center in Florida as soon as Thursday, before heading inside the spaceport’s huge Vehicle Assembly Building for the first time next month.
