Astronauts aboard the Space Shuttle Atlantis, mission STS-43, use an Apple Macintosh Portable computer to send what is considered the first e-mail from space. Using the AppleLink online service, Atlantis astronauts Shannon Lucid and James C. Adamson sent the following message:

Hello Earth! Greetings from the STS-43 Crew. This is the first AppleLink from space. Having a GREAT time, wish you were here,…send cryo and RCS! Hasta la vista, baby,…we’ll be back!

The AppleLink software on the Macintosh was specially configured to connect to NASA’s communication system which allowed the Shuttle to interface with Apple’s proprietary network from space. The Macintosh Portable itself only had very minor modifications to operate in space.
