I am here finally. Want to get a drink?

Falcon Heavy launch and recovery today means we will go to Mars before 2030 and SpaceX will land there a decade before NASA. Remarkable turning point from government-based space exploration to private.

After Asteroid Bennu’s next very close flyby (between Earth and the Moon) in 2035, it’s orbit could be altered enough to collide with Earth in 2185–or not. That makes the Osiris-Rex mission even more interesting.

One of the most fascinating space odysseys ever launched is the Osiris-Rex mission to capture a sample from asteroid Bennu and return it to a Earth. The spacecraft will reach Bennu in September. Bennu crosses paths with Earth every six years. https://t.co/CLTtgageTN via @youtube

[Stephen Petranek @Petranek]

Well, keep moving. It’s a big airport

@jennalee @guywalters @n_vpatel @zdroberts @MissBicks @SydneyBucksbaum @east_coastbias @SamuelRMurrian @jgrebes @alejandrotrojas Dang. Had only 13-minutes to make it at DCA with two bus rides. Unbelievable. The attendant said she had to close the door in 30 seconds so I ran to the plane and got on without a ticket (my old one was for the cancelled connecting flight). Then they had to figure out my seat :)

@jennalee @MissBicks @zdroberts @guywalters @n_vpatel @SydneyBucksbaum @east_coastbias @SamuelRMurrian @jgrebes @alejandrotrojas Oh dear, you have been at space camp way too long

[Stephen Petranek @Petranek]

@MissBicks @zdroberts @jennalee @guywalters @n_vpatel @SydneyBucksbaum @east_coastbias @SamuelRMurrian @jgrebes @alejandrotrojas Emily and I are experiencing airline/snow stress

Just another upside-down/spin-around day at NASA experiencing unusual attitudes.

At Marshall Space Flight Center in the Shuttle simulator with my co-pilot Sammy Rotibi, star of NatGeo’s Mars series

SpaceX, ULA, Orbital, and Blue Origin please note: this week the Voyager spacecraft, now 21 billion km from Earth in interstellar space, answered commands to fire its thrusters —after 37 years of inactivity. They worked perfectly. Inspiring engineering from Aerojet Rocketdyne

[Stephen Petranek @Petranek]

Confirmed for lift-off

Elon Musk reaffirms SpaceX will land humans on Mars by 2024. Can use same rocket to fly you between any two cities on Earth in 30 mins
