The best video NASA has ever produced – ’7 minutes of terror’ – landing a robot on Mars

 

On Aug. 5 or Aug. 6, depending on which part of the country you’re in, the Curiosity spacecraft careening toward Mars will hit the Red Planet’s atmosphere, deploy a supersonic parachute and either land safely on the planet’s surface or perish. It’s dramatic stuff, and NASA has produced this Hollywood-style YouTube video, complete with animation and suspenseful music, to preview the landing, evoke that drama and put viewers on the edge of their seats.

As engineers explain, it will take seven minutes for Curiosity to travel from the edge of Mars’ atmosphere to the surface, going from a speed of 13,000 mph to zero. “If any one thing doesn’t work just right, it’s game over,” engineer Tom Rivellini says.

Because Mars is so far away, it actually takes 14 minutes for the spacecraft’s signal to reach Earth. So by the time we learn the spacecraft has hit the top of Mars’ atmosphere, Curiosity will have either have survived the landing or perished for a full seven minutes.

Photos of the skydiver who parachuted into the Olympics dressed as the Queen

God save the queen. And get her a razor for her five o’clock shadow.

The stuntperson who was featured during that showstopping moment in Friday night’s Opening Ceremony when Queen Elizabeth jumped out of a helicopter with James Bond was a better actor than you ever knew. A closer look reveals it was a man dressed as the queen and pulling the cord on the parachute.

Gary Connery, above right, is a 42-year-old stuntperson who has appeared in British television shows and popular movies including the “Indiana Jones” series. He’s a jumping daredevil, having set the record for highest free jump and making close to 1,000 skydives in his career.

Connery was tasked with playing the queen during the ceremony, a role which included jumping out of the helicopter and landing precisely on a nearby bridge and, perhaps more dangerously, wearing a tiara and pearls.

How the astronauts on the International Space Station get back to our planet

This Sunday (July 1, 2012), three members of the International Space Station crew will return to Earth on board a Kazakhstan-bound Soyuz craft, after over six months in orbit. Don Pettit and Andre Kuipers, two of the returning astronauts, and Joe Acaba, who arrived at the station in May, discuss life on board ISS, the visit of the Dragon capsule, and current activities in space.

FLORA LICHTMAN: Just another day at SCIENCE FRIDAY, calling space.

Station, this is National Public Radio. How do you hear me?

DON PETTIT: NPR, we hear you loud and clear.

***

LICHTMAN: Don Pettit, walk us through how you’ll get back to our planet this weekend.

PETTIT: We will get in our Soyuz spacecraft and under the command of Oleg Kononenko, and Andre Kuipers will be flight engineer one or board engineer one, and I’m board engineer two. And we work together to get this spacecraft back home, starting off with undocking.

We start off, we get inside, the close the hatch, we have to do a leak check, make sure the hatches don’t leak. And then we strap in and undock, and then we do a de-orbit burn. And then as we hit the atmosphere, the spacecraft separates so that only the descent module comes through the atmosphere in one piece.

And then our parachute comes out, and we go thump, roll, roll on the steppes of Kazakhstan.
