When did sputnik 2 return back to earth?

Answer 1

There were in fact several Sputnik satellites, but I imagine you're asking about the very first.

Sputnik-1 spent 3 months in orbit before re-entering and burning up. It was launched on October 4 1957, and was destroyed on January 4 1958. So it's location today would be... nowhere. It's believed to have been destroyed entirely. There is one piece left of sputnik, http://en.wikipedia.org/wiki/Sputnik_1 This metal arming key is the last remaining piece of the first Sputnik satellite. It prevented contact between the batteries and the transmitter prior to launch. Currently on display at the National Air and Space Museum.

Answer 2

It didn't. Like Sputnik-1 a few months earlier, Sputnik-2 steadily lost energy because of

air resistance, and burned up during its re-entry into the lower atmosphere.

It was several years after the Sputnik series before a vehicle was able to return from orbit

and land, or be recovered during re-entry.

Answer 3

It didn't. After roughly 6 months in orbit, it re-entered the atmosphere on April 14 1958,

and was completely incinerated (burned up), along with the corpse of the dog Laika, which

had only lived for a few hours after its launch on November 3 1957.

Answer 4

Nowhere.

It burned up on reentry after some time in orbit.

Answer 5

There was more than one Sputnik.

Most didn't really go anywhere. They were launched into low-Earth orbit and stayed there until they fell back into the atmosphere and burned up.

Answer 6

After 3 months in orbit the Sputnik I satellite re-entered the atmsophere and disintegrated; the debris of it landed in the Pacific Ocean. No pieces of it have ever been found.

Answer 7

Yes. After 60 days in space it crash landed back on Earth, although it wasn't Designed to land. The dog was dead before it crashed.

Answer 8

Nowhere really.

It was launched into low-Earth orbit and stayed there until it fell back into the atmosphere and burned up.
