Picture- The ISS

A 150 billion pounds project which brought the sci-fi
ideas of a space station to fruition!

Sputnik

So I haven't posted in a while and I think it's about time that I do again. So what is Sputnik? Sputnik is the first man made object ever sent to space. This kicked off the space race between Russia and the USA but that is for another day. Sputnik as you saw on the picture is a Russian satellite. It had a metal ball and then 4 radio antenna's protruding out of it. Launched in 1957 this "cute" satellite was only 58 cm (22 inches) in diameter. It was used to broadcast from space as amateur and professional broadcasters listening in from across the world. The signals lasted for 22 days before it burnt up in re-entry after 3 months in low earth elliptical orbit.

The probe was launched by a general rocket propulsion system before being detached, as said before, in low Earth orbit.

So that's it for today, I will post the picture of the day. The satellite topic is nearly over, I'd say about four or five satellites (possibly more) I will also put a poll up for people to pick what topic next. There will be three options- The space race, Apollo missions or Particles in space ( if particles wins make sure to check the particle series I did previously. So I will post tomorrow and remember to comment on any mistakes or suggestions.
