Cheaper, Better Satellites Made From Cellphones and Toys
MOUNTAIN VIEW, California — Instead of investing in their own computer research and development, engineers at the NASA Ames Research Center are looking to cellphones and off-the-shelf toys to power the future of low-cost satellite technology.
The smartphone in your pocket has about 120 times more computing power than the average satellite, which has the equivalent of a 1984-era computer inside.
“You can go to Walmart and buy toys that work better than satellites did 20 years ago,” said NASA physicist Chris Boshuizen. “And your cellphone is really a $500 robot in your pocket that can’t get around. A lot of the real innovation now happens in entertainment and cellphone technology, and NASA should be going forward with their stuff.”
The biggest challenge of sending cellphones and toys into space is whether the parts can get up there without shaking apart and work in a vacuum at extreme high and low temperatures.
To do some preliminary testing, two Nexus One cellphones caught rides on two rockets on July 24 that launched 30,000 feet into the atmosphere at a maximum speed of mach 2.4 (about 1,800 miles per hour). One of the rockets crashed into the ground after its parachute failed, but the other made it back with the cellphone unscathed.
