Stephen Hawking and Neil deGrasse Tyson Say #HelloFromEarth

Tomorrow, we’re broadcasting Live From Space! As we gear up for the live two-hour event, we’re asking fans to wave to the astronauts up in space with hashtag #HelloFromEarth on Instagram with a photo or video. Stephen Hawking and Neil deGrasse Tyson are joining in on the fun. Check out their messages to the astronauts, submit your own, and browse the gallery of submissions.

“The colonization of outer space is the key to humankind’s long-term survival.” Professor Stephen Hawking says #HelloFromEarth to the astronauts aboard the International Space Station who are taking the first bold steps towards humanity’s future beyond Earth.

“Do you feel like barfing the whole time??” Cosmos host Neil deGrasse Tyson poses a very serious question to the astronauts on board the International Space Station.

Beam up your own question using #HelloFromEarth and don’t miss the premiere of #LiveFromSpace TOMORROW NIGHT at 8pm ET (5pm PT)!
