NASA delivers bounty of asteroid samples to Earth | Science | AAAS

By

It only took some 10 minutes for the suitcase-size capsule to fall through the clear skies of the western United States.

After arriving in 2018, OSIRIS-REx spent 2 years orbiting its target, Bennu, a 500-meter-wide, carbon-rich, near-Earth asteroid.

When the orbiter settled to the surface to collect a sample in October 2020, Bennu’s consistency made the attempt harrowing, with the spacecraft’s sampling arm plunging unexpectedly deep into Bennu’s rubble pile.

SANTA CRUZ, CALIFORNIA "Dad, did you ever imagine that your formula would become so famous?" I ask the kind-eyed, 91-year-old person next to me on the patio. My dad, Frank Drake, is quiet for a moment. Perhaps he's thinking back to the November day 60 years ago when he unceremoniously drafted a formula that went on to shape humankind's hunt for extraterrestrial civilizations.

Studies of meteorites have found them to be surprisingly rich in water, suggesting that early in our planet's history 4.6 billion years ago, incoming asteroids delivered water and allowed Earth to become the h

Avi Loeb: Two things. In 2017, there was an object — the first one that was identified from outside the solar system that arrived close to Earth — and it didn't look like anything we've seen before. It didn't look like a comet, it didn't behave like an asteroid. Loeb: Yes. And I thought maybe it's artificial in origin. And, in fact, I wrote a book about it, Extraterrestrial, that was published six months ago. And then a month ago, there was a report delivered to Congress saying: there are things in the sky above the U.S. whose nature is not identified.

Now Multiply Labs, which was founded by Fred Parietti PhD '16 and former visiting PhD at MIT Alice Melocchi, is hoping to bring the speed and precision of its robots to a new type of advanced treatment. Multiply Labs is attempting to automate many processes that can currently only be done by highly trained scientists, reducing the potential for human error. The platform will also perform some of the most time-consuming tasks of cell therapy production in parallel. For instance, the company's system will contain multiple bioreactors, which are used to grow the genetically modified cells that will be injected back into the patient.
