Lasercom through the solar system 100 times
time the next time you complain about your broadband connection slow, spare a thought for NASA. The U.S. space agency is now based on the radio to transmit information across the solar system and beyond, which not only uses lots of energy but it is a slow transfer rate. The current connection with Mars, for example, can send data at speeds of only about 6 Mbps. The same as the average broadband connection in the UK, and you do not have to share with an entire planet

This is not just for future use on Mars, is an immediate need, as the current connection is too slow for satellites in orbit there. The Mars Reconnaissance Orbiter sends periodic high-resolution images of the Martian surface. In about 2 gigabytes each, even after compression of images will take about 90 minutes to reach Earth. With a new Lasercom 100 Mbps, which could be done in five minutes. - NASA today announced an update is long overdue. It will test a new system to send signals through the laser beams instead of radio, the spatial equivalent of using fiber optic cables. Sending a laser pulse, not only requires less energy, but can carry more information. This technology should be Lasercom ready to launch in 2015 and increase the speeds of up to 100 times, which certainly puts 14% of Britain is still struggling with connections of 2 Mbps in the shadows. NASA has provided a permanent Internet connection to the International Space Station since January 2010, which allows astronauts to update their Facebook accounts and send tweets whenever they want. The update will not only give them a faster connection, so you can watch YouTube videos without a break all that boring, but also pave the way for future manned missions to Mars and beyond and science.
