🚀 & are completing key milestones for the #DARTmission!
Last week, the DART spacecraft was encapsulated inside the payload fairings that will protect it during launch atop a #Falcon9 and teams completed a successful Flight Readiness Review: go.nasa.gov/3FEWPGk
T-2 hours! 🛰️
We are only 2 hours away from the liftoff of U.S.-European Sentinel-6 Michael Freilich satellite and the team is on console and ready to proceed. #SeeingTheSeas
What a view! 🚀
Today, an #Antares rocket successfully launched the S.S. Katherine Johnson #Cygnus spacecraft carrying about 8,000 pounds of cargo and providing a ride to IT-SPINS, our ELaNa 33 CubeSat. Follow the ELaNa missions: go.nasa.gov/3l7RDQo
3... 2... 1... IMPACT!🛰🎯🪨
#ICYMI the world watched LIVE as struck an asteroid in a first-ever test of #planetarydefense!👀
Get the up-close view as #DARTMission impacted asteroid Dimorphos! The test will give more information on protecting Earth from asteroid threats.
Spacecraft. Stacked.
Continuing on its path to preparation for next month’s launch, the rover spacecraft is, well, put together.
Liftoff is targeted for July 20 on board a Atlas V rocket at 9:15 a.m. ET. Learn more: blogs.nasa.gov/mars2020/
