A probe sent the first year after the Migration failed to arrive.

The probe will then send this information back to Earth or a manned spacecraft.

Thus, a probe sent may have been nonfunctional for millions of years before humans learn of its existence.

"Data, what happens to the signals that the probe is sending toward the field?"

The probe collected 170 grams of lunar dirt and sent it back to Earth.

Shannon was looking at a view of one of those volcanoes now, sent back from a probe on Io's surface.

The probe descended and sent pictures and other data back for scientists to study.

"They didn't interfere with the video that the probe sent," Serena said.

A probe sent onto the surface of the planet has found what looks to be possible signs of life.

Life was believed to exist here but nothing substantial had ever been detected with the probes sent into this region.
