NASA Kids Science News segment explaining what the Mars Rover is and what it did.
Hi, I'm Ariana.
00:00:00
And I'm Ariana with more science news you can use.
00:00:02
Did you know that there was a remote-controlled car on Mars?
00:00:08
On July 4, 1997, Pathfinder landed on Mars
00:00:12
and sent out a small robot called Sojourner to explore.
00:00:16
How did NASA control Sojourner from Earth?
00:00:19
With radio waves.
00:00:22
But Mars is so far away.
00:00:23
Right. The radio waves took about 11 minutes to make a round trip.
00:00:25
But NASA scientists had a good solution.
00:00:29
They sent instructions to Mars once a day.
00:00:31
Then what?
00:00:34
Pathfinder recorded the instructions it received from Earth
00:00:35
and then sent them on to Sojourner.
00:00:38
What's going to happen in the future?
00:00:40
This time, NASA will talk to the rovers using two satellites
00:00:42
already in orbit around the Red Planet.
00:00:46
These two rovers will be bigger, go farther, and operate longer on Mars.
00:00:48
