Synopsis: Satellites keep an eye on everything, from the oldest stars to the latest forecast.
Excerpt: Maybe you've heard of the most famous astronomical satellite: the Hubble telescope. Launched in 1990, this telescope can look so far into space that we can see stars that formed right after the Big Bang created our galaxy. Those starts are about 13.77 billion years old.

As you've already learned, a satellite must be launched into space. But as you've probably noticed when you jump in the air, only to quickly fall to the ground, gravity is tough to beat. And a satellite is a lot heavier than you are. The first human-made satellite, Sputnik, was launched in 1957 and weighed 184 pounds. In contrast, the Hubble telescope weighs 24,500 pounds.

Question: Three of these statements about Sputnik and Hubble are correct. Which one is not correct?
  1. They weighed the same amount.
  2. They were both launched after 1950.
  3. They are both human-made satellites.
  4. They both orbited the Earth.
