Congratulations 🥂👏🪐 @NASASolarSystem @NASA we can't wait to have a chance to work on material from #Bennu #OSIRISREx @kh_freeman @Astrobiology @PSUGeoscience @PSUEMS
Live Now: #OSIRISREx delivers the US's first pristine asteroid sample after a 3.86 billion-mile journey. Watch landing live from @DeptOfDefense's Utah Test & Training Range. Use #AskNASA to send us your questions. xitter.cf/i/broadcasts/1gqxvQkbo…

Not to take anything away from the good folks who made #OSIRISREx happen @NASA 🥂, but we need to get this #scicomm right: #Hayabusa happened! A sample from #asteroid #Itokawa was returned to Earth in 2010 by the Japanese space agency in an elegant and successful mission.

An exciting morning! And don’t forget Allie Baczynski—we couldn’t do it without her!
. @NASA's #OSIRISREx just delivered samples to Earth and our experts including Kate Freeman and Chris House watched. These researchers are one of several groups gaining access to samples from the asteroid Bennu, which might hold clues about the origins of our solar system.

A thrilling morning! So glad @jmacalad and friends from @psuems @GeoscPSU and @AstrobiologyPsu could join us for the fun! 🔭🔬🧪
The watch party @kh_freeman continues, here with @JARNBRAK, celebratory coffee drink in hand, watching a helicopter lift the OSIRIS-REx sample capsule away from the landing zone to a clean room @AstrobiologyPsu @GeoscPSU @PSUEMS

In the interest of U.S. Japan relations, I'm duty-bound to clarify that this is NOT the first time humanity has returned an asteroid sample to Earth #Hayabusa @NASAAstrobio
WATCHING NOW: A capsule released from the #OSIRISREx spacecraft is scheduled to land in Utah this morning. It contains material from the asteroid #Bennu, and some of it will be analyzed @kh_freeman @GeoscPSU @PSUEMS @AstrobiologyPSU !!! nasa.gov/nasalive

A piece of #Bennu #asteroid is coming soon to @AstrobiologyPsu @PSUEMS @PSUresearch and my colleague @kh_freeman is throwing a party!
We’re TEN days away from receiving the U.S.'s first asteroid sample, allowing us to study some of the oldest organics in our solar system! Catch up on OSIRIS-REx’s historic mission #ToBennuAndBack and see what’s in store for Sept. 24: go.nasa.gov/3raUOA1
