What are 2 discoveries that space probes have made?

Here are five of the many discoveries New Horizons made as it zeroed in on Pluto.

• Pluto’s Real Size. On Monday, NASA said information from New Horizons revealed Pluto is 1,473 miles in diameter — larger than what scientists previously believed.
• Pluto’s ‘Heart’
• Geology.
• First Look at Hydra and Nix.
• Charon.

How does NASA control space probes?

NASA and the probes communicate using radio waves, just like a walkie talkie. And then, just like on a remote controled car, NASA can use these signals to tell the probe what to do. Probes have two ways of moving in space. They allow the probe to turn, speed up and slow down.

How far can we communicate in space?

Ground station antennas range from the small very high frequency antennas that provide backup communications to the space station to a massive, 230-foot antenna that can communicate with far-off missions like the Voyager spacecraft, over 11 billion miles away.

How do you communicate in deep space?

Spacecraft send information and pictures back to Earth using the Deep Space Network (DSN), a collection of big radio antennas. The antennas also receive details about where the spacecraft are and how they are doing. NASA also uses the DSN to send lists of instructions to the spacecraft.

What is a Chinese astronaut called?

taikonaut (plural taikonauts) A person who travels in space for the Chinese space program; a Chinese astronaut. [ from 1998.]

Is Voyager still taking pictures?

After Voyager 1 took its last image (the “Solar System Family Portrait” in 1990), the cameras were turned off to save power and memory for the instruments expected to detect the new charged particle environment of interstellar space. Mission managers removed the software from both spacecraft that controls the camera.

What are the two main areas of the body affected by long term space travel?

Living in this type of environment impacts the body in three important ways: loss of proprioception, changes in fluid distribution, and deterioration of the musculoskeletal system.

How space travel affects the human body?

Without the proper diet and exercise routine, astronauts also lose muscle mass in microgravity faster than they would on Earth. Moreover, the fluids in the body shift upward to the head in microgravity, which may put pressure on the eyes and cause vision problems.
