How did Laika eat in space?

Sputnik and Muttnik Soviet scientists assumed that a stray dog would have already learned to endure harsh conditions of hunger and cold temperatures. Laika and two other dogs were trained for space travel by being kept in small cages and learning to eat a nutritious gel that would be their food in space.

That satellite was Telstar 1. It launched on July 10, 1962. The mission was a cooperative effort between AT&T and the space agency to demonstrate, “the feasibility of transmitting information via satellite.”

What killed Telstar?

Telstar’s orbit took it regularly through the belt of radiation that this caused, and within six months, the satellite was rendered useless. JFK’s administration had already sent up replacements, and so Telstar, hit by the odd meteorite and stray piece of debris, was left slowly to disintegrate in its eternal orbit.

How many dead satellites are in space?

There are more than 3,000 dead satellites and rocket stages currently floating in space, and up to 900,000 pieces of space junk ranging from 1 to 10 centimetres in size — all large enough to be a collision hazard and a potential cause for disruption to live missions.

Will all satellites eventually fall to Earth?

The short answer is that most satellites don’t come back to Earth at all. … Satellites are always falling towards the Earth, but never reaching it – that’s how they stay in orbit. They are meant to stay there, and usually there is no plan to bring them back to Earth.
