Sputnik, Mariner, Gemini,Mercury?

Question

I have a couple of questions

1)Who worked on each of those missions?

2)What was learned by each of these missions?

Any additions info would be great

Answer 1

<<Sputnik, Mariner, Gemini,Mercury>>

Things that were hurled from the ground?

Your quetion is ill formed. Sputnik was an artificial sattelite, Mariner was an interstellar space craft, while Gemini/Mercury was the first two series of U.S. spacecraft designed to put man into earth orbit. I think my first description is the best you will get based on your question.

Answer 2

Place your question in correct category if you want answer. Try Science & Mathematics, Astronomy, Engineering.  Since none of these spacecraft were ever cars, doubtful to be answered here.

Answer 3

Larry, your in Aircraft,  Dipstick!
