When spacecraft send signal's.?

-------------------------------------------------------

answers:
PhotonX say: They send a directional radio beam toward Earth. Some spacecraft have their radio dishes mounted on the spacecraft body itself, which has to change its attitude to point toward Earth and NASA's Deep Space Network. Others have antennae that can be gimbaled toward Earth no matter what the spacecraft attitude is. Some use an orbiter/lander scheme, with the lander or rover communicating with the orbiter in space, and the orbiter communicating in turn with Earth.

Ronald 7 say: Low Orbit Craft can easily send signals back down to Earth where there are many receivers
For far away Probes have the Deep Space Network to bounce off towards the terrestrial receivers
New Horizons has passed Asteroid Bennu and set the record for man's farthest study of a body
40 Billion Kms away at 05-00 this morning
And it is still halfway to Earth

Spacecraft send signals to Earth and they are intercepted by the Deep Space Network or other receiver dishes. Since there is nothing between the spacecraft and Earth signals are not reflected or blocked so they can travel a long way.

Morningfox say: Maybe if the cell phone and receiver tower used 85-foot dish antennas ....

wandycakes say: Why is it when spacecraft send signal's back to earth over BILLIONS of miles they reach earth with out much of a problem. Yet, mobile phones need multiple masts to send a signal just a few hundred miles?
