ELI5: Explain Like I'm 5

STS-75

STS-75 was a space shuttle mission conducted by NASA in February 1996. A space shuttle is like a big, fancy airplane that goes to space. The mission had a big, special object called a "tether" that was 12.8 km (8 miles) long, and it was attached to a space shuttle called "Columbia."

Now, imagine a really long string that you hold in your hand while twirling it around. That's kind of what the tether was like, except in space, it was pretty complicated! NASA used the tether to do some science experiments that would help us better understand the Earth's magnetic field and the space environment around it.

During the mission, the space shuttle and its crew were able to successfully deploy the tether, and it hung there in space connected to the shuttle. But then, something unexpected happened. The tether started to break! Scientists aren't completely sure why it happened, but some think it could be because of electric charges in the space environment.

Even though the tether broke, NASA was still able to gather data from the experiment, and it gave scientists a lot of valuable information about the Earth's magnetic field and space environment. Overall, STS-75 was a really important mission that helped us understand more about space and our planet.
