A touch of history for our first asteroid sample

return mission A safe return from

the International Space Station And a big move in preparation for

Artemis I a few of the stories to tell you about This Week at NASA!

On Oct. 20 some 200 million miles from Earth NASAs OSIRIS-REx spacecraft extended

its robotic arm, and in a first for the agency, successfully touched asteroid Bennu long enough

to collect dust and other surface material to be returned to Earth for study in 2023.

And we have touchdown! Touchdown declared! (applause and cheering)

Bennu contains material from the early solar system that could help

researchers learn more about the origins of life on Earth.

NASA astronaut Chris Cassidy safely returned to Earth from the International Space Station

on Oct. 21, Eastern Time. Cassidy and Russian cosmonauts Anatoly Ivanishin and

Ivan Vagner landed in their Soyuz spacecraft just hours after leaving the station.

The landing wrapped up a six-month mission for the trio aboard the orbital outpost.

On Oct. 20, the mobile launcher that will be used with our Space Launch System (SLS) rocket

and Orion spacecraft for Artemis I, was rolled out to Launch Pad 39B at our Kennedy Space

Center in Florida. The trek to the pad helped prepare the launch team for the actual launch

of Artemis I next year. The mobile launcher will stay at the pad for about two weeks

to practice logistics, validate timelines, and for cleaning.

Preparations continue for the Nov. 10 launch of the Sentinel-6 Michael Freilich spacecraft.

The world's latest ocean-monitoring satellite, named after the late Dr. Michael Freilich,

former director of NASA's Earth Science Division, is one of two identical spacecraft

that will collect extremely precise sea surface height measurements.

Registration is underway for NASAs 27th Human Exploration Rover Challenge,

targeted for April 15-17, 2021. The annual student competition features student-built rovers taking

on a course simulating terrain found on the Moon, Mars and other rocky bodies in the solar system.
