NASA plans to launch a new satellite today (Jan. 30) to upgrade the network used to send messages back and forth between spacecraft and the ground. <\/p>\n
The space agency is set to launch the new Tracking and Data Relay Satellite K (TDRS-K for short) at 8:48 p.m. EST (0148 Jan. 31 GMT) today from Cape Canaveral Air Force Station in Florida. The spacecraft will blast off atop a United Launch Alliance Atlas 5 rocket. <\/p>\n
You can watch the launch live on SPACE.com through NASA TV starting at 6:15 p.m. ET (1115 GMT). <\/p>\n
Cold front <\/p>\n
Weather at the launch site is looking promising, but NASA officials aren't taking any chances, and won't launch the rocket unless skies are clear. <\/p>\n
\"Now we're looking at a 40-percent chance that a weather rule will be violated,\" Joel Tumbiolo, a NASA launch weather officer, said on Monday. <\/p>\n
The rocket that will carry TDRS-K to orbit has already been rolled out onto the launch pad, but a cold front is approaching Cape Canaveral that could delay the launch. Electrically active clouds heralding the arrival of the cold front might create dangerous conditions. <\/p>\n
TDRS-K has an estimated cost of between $350 million and $400 million, not counting the cost of the rocket to launch it. The spacecraft is the first of three new satellites due to lift off between now and 2015 to bolster the TDRS communications satellite network, which relays data and messages between spacecraft in orbit and ground stations.

Thanks to the positioning of ground elements and the TDRS network of satellites around the world, NASA scientists have constant communication with orbiting spacecraft. The network is responsible for space-to-ground communication with the International Space Station as well as the Hubble Space Telescope. <\/p>\n
