Recently, the International Space Station (ISS) marked a historic milestone — the 25th anniversary of the launch and docking of the Unity module.
Also known as Node 1, the module was the first U.S.-built component of the ISS. During the intervening 25 years, the ISS has been home to a rotating crew from a host of countries and the site of groundbreaking experiments that will help future astronauts and earthbound individuals alike.
To learn about discoveries made on the ISS, let actor Mark Hamill, of Star Wars fame, take you on a journey to see how science in space reflects — or diverges from — innovations seen in the movies or on TV.
