Ask any deep space navigator like Jill Seubert what makes steering a spacecraft difficult, and they'll tell you it's all about the timing; a split-second can decide a mission's success or failure. So what do you do when a spacecraft is...

Humans have never visited another planet, but we can send special spacecraft called probes to visit them for us! One of those probes, called Voyager 1, has gone deeper into space than any other, and it's sent us some amazing pictures...

Voyager 1 may be out of our solar system (and 40+ years old) but we're still getting plenty of new data from our interstellar space probe.

On January 24, 1986, NASA's Voyager 2 spacecraft flew by Uranus. This was the first time any spacecraft had ever visited Uranus. Its twin spacecraft, Voyager 1, only made it as far as Saturn before veering out of the plane of the solar...

On July 9, 1979, NASA's Voyager 2 spacecraft made its closest approach to Jupiter. It came within 354,000 miles (570,000 kilometers) of the planet's cloud tops. Voyager 2 was one of two space probes launched by NASA in 1977 to study the...
