Roving Mars

00:00:25 Space exploration began with dreaming. Thousands of years of humans staring

00:02:17 of scientists and engineers whose mission was to discover if Mars ever had

00:03:27 where some of the most innovative engineers in the country work.

00:04:47 We can only launch when the two planets are properly aligned

00:06:04 We've had to fold everything into these complicated shapes to get this system

00:07:32 The rovers have very different personalities.

00:08:41 The air bags are like the air bags in your car but way more expensive.

00:09:53 Uh, well, I mean, the drop was successful.

00:11:28 an elbow, and a wrist. The arm tucks up tight under the front of the vehicle

00:12:39 It goes way beyond this single mission.

00:13:55 But it's gonna be very hard to say goodbye.

00:18:30 7 MONTHS AFTER LAUNCH

00:19:43 If we deploy the parachute too low of an altitude, it won't open in time

00:20:57 moving at a speed of twelve thousand one hundred ninety-two miles per hour.

00:22:38 however...however, we currently do not have signal from the spacecraft.

00:26:23 We sent Spirit to Gusev Crater, a crater in the southern highlands of Mars.

00:27:50 For driving, the rover has these kinda googly-eyed cameras that it uses

00:28:56 below the weathered surface.

00:30:11 over its lifetime.

00:32:04 The blueberries, it turns out, are made of hematite

00:33:29 All the discoveries that Opportunity made about water

00:34:46 and started to find stuff that was different from anything we'd seen.

00:35:54 And if that happens, the rover's going to get too cold.

00:37:33 In many ways, they are our wildest dreams.
