The first mission, #Polaris Dawn, will launch NET Q4 of this year, taking advantage of Falcon 9’s and Dragon’s full capabilities. The mission will culminate in an attempt at the first-ever commercial spacewalk, using a special #SpaceX EVA suit.

- Scott Poteet, a retired USAF lieutenant colonel
- Sarah Gillis, Lead Space Ops Engineer at #SpaceX & astronaut trainer
- Anna Menon, Lead Space Ops Engineer at SpaceX & Mission Director
Another Crew Dragon flight will follow soon after #Polaris Dawn, building upon the foundation of that mission in preparation for the first crewed flight on #Starship. No NET date has been set for this mission.
An asteroid fell through the Earth’s atmosphere over the Chelyabinsk Oblast in southern Russia, resulting in a meteor air burst that created sonic booms and a bright flash that rivaled the then-rising Sun. (1/14)

Analysis and estimates state the object measured in at approximately 20m across and weighed in at around 10,000 tons.
It entered the atmosphere at a shallow 18° angle, with a relative velocity of ~69,000 km/h/42,700 mph - just over 11 miles per second. (2/14)
The heat and friction of atmospheric entry resulted in the object exploding at a height of 18.5 miles above ground, creating a flash that was confirmed to be brighter than the Sun.
Several small chunks of the meteor survived entry & impacted in areas west of Chelyabinsk. (3/14)
