Astronauts eventually have internet access in space. According to the website of NASA, “Astronauts on board the International Space Station received a special software upgrade this week – personal access to the Internet and the World Wide Web via the ultimate wireless connection.” This is one giant leap for the Internet.
Expedition 22 Flight Engineer T.J. Creamer made first use of the new system early morning on Jan, 22, 2010, when he posted the first single-handed update to his Twitter account, @Astro_TJ, from the space station. Tweets from space, previously had to be e-mailed to the ground where support personnel posted them to the astronaut’s Twitter account.
T.J. Creamer said in his first tweet early this morning, “Hello Twitterverse! We r now LIVE tweeting from the International Space Station — the 1st live tweet from Space! 
More soon, send your ?s,”
The personal Web access, named the Crew Support LAN, capitalizes of existing communication links to and from the station and gives astronauts the aptitude to browse and use the Web. Direct private communications will provide astronauts to enhance their quality of life during long-duration missions by aiding to ease the seclusion associated with life in a closed environment.
As per the site of NASA, “During periods when the station is actively communicating with the ground using high-speed Ku-band communications, the crew will have remote access to the Internet via a ground computer. The crew will view the desktop of the ground computer using an onboard laptop and interact remotely with their keyboard touchpad.”
