I think the Russians might agree. Sputnik 2 was a major breakthrough in space exploration, although I feel Laika may not agree.
Sputnik was a series of satellites built and launched by the then Soviet union. Sputnik 1 and 2 became the first two man made objects to attain orbit around the Earth.
the 2 in Sputnik 2 means it is the second to be built.
Yes, both were launched from the Baikonur Cosmodrome.
Sputnik I, launched on October 4, 1957, was the first man-made object to successfully achieve Earth orbit.It was followed by Sputnik II on Sputnik 2, on November 3, 1957.The first US satelllite was Explorer I, launched on January 31, 1958.
Sputnik-2
The dog, Laika, died due to temperature increase.
Sputnik 1, the first man made object to orbit the earth. And we've been polluting like crazy up there ever since.
Sputnik 2 has been in space for sixty (60) days.
They were unmanned, although Sputnik 2 carried a dog into space.
Sputnik 2 was a solid object which was conical is shape. Solid objects do not have perimeters.
