The farthest space mission in the world is the farthest we have ever gone.
But if you want to reach it, you’ll have to put your fartest spacecraft through some pretty extreme tests.
The fartest flight ever attempted, for example, is a record.
The highest orbit a spacecraft can reach is about 4,800 miles (7,300 kilometers), and the fartest orbital velocity of any spacecraft is 1.3 miles per second (1.9 km/s).
But there are other hurdles.
NASA wants to be able to send a spacecraft that’s closer to the sun than any other.
It’s hard to imagine a craft that’s more distant than this.
But NASA says it’s not too far off.
It just has to send it closer.
To do that, NASA has launched a new mission to send its probe into space, the Dawn probe, which will fly toward Ceres, the largest moon in our solar system.
The probe will arrive in Ceres in the early 2020s.
It will be the fartlethest spacecraft ever.
The mission will test the spacecraft’s performance in low-Earth orbit (LEO), a place the craft would reach without gravity.
The Dawn probe’s mission is about to begin, but before Dawn arrives, it’s taking some of its most ambitious tests yet.
The first stage of Dawn’s engine is expected to be fired on Dec. 5.
But this is the first stage that’s going to blast off.
The second stage will fire on Dec
