Using precise autonomous navigation algorithms, NASA’s OSIRIS-REx spacecraft will descend to the surface of an asteroid next year, aiming to retrieve rock specimens for return to Earth from a gravelly pit flanked by hazardous boulders, scientists said Thursday.

Earth observation, deep space exploration big winners in new ESA budget

European Space Agency member states on Thursday committed nearly 12.5 billion euros ($13.8 billion) to fund ESA programs over the next three years, promising money to grow Europe’s fleet of satellites studying Earth’s changing climate, contribute to NASA-led lunar exploration efforts, and continue ESA’s participation in the International Space Station until 2030.

Japanese sample return craft departs asteroid, heads for Earth

November 13, 2019 Stephen Clark

Closing out a year-and-a-half of exploration, surveys and sampling operations at asteroid Ryugu, Japan’s Hayabusa 2 spacecraft fired thrusters in a departure maneuver Wednesday and headed for Earth with specimens snatched from the asteroid’s dark and rocky surface.

The first set of proposals for a new class of small robotic probes NASA wants to dispatch across the solar system came in with higher cost estimates than agency officials expected, a NASA manager said Sunday.

Japanese spacecraft snags second sample from asteroid

July 11, 2019 Stephen Clark

Scientists celebrated another success with Japan’s Hayabusa 2 spacecraft late Wednesday (U.S. time), when the robot explorer accomplished a second pinpoint touch-and-go landing on asteroid Ryugu, this time to collect a sample of pristine dust and rock excavated by an explosive impactor earlier this year.

Hayabusa 2 cleared for second touchdown on asteroid

July 3, 2019 Stephen Clark

Ground teams have approved plans for Japan’s Hayabusa 2 sample return mission to briefly land on asteroid Ryugu for the second time July 11, aiming for a targeted touch-and-go to gather material exposed by an explosive impactor released by the robot explorer in April.

Japanese probe readies for another possible touch-and-go on asteroid

June 6, 2019 Stephen Clark

Approaching the one-year anniversary since its arrival at asteroid Ryugu, Japan’s Hayabusa 2 spacecraft has deployed a target marker near an artificial crater created by an explosive charge in April, a guide post that could help the probe steer toward another pinpoint touchdown to collect a second batch of samples for return to Earth.
