Smartphone fired into space to see if screams can be heard
A smartphone has been blasted into orbit from India by a team of researchers from the University of Surrey.
They hope to use a purpose-built app to test the theory,
immortalised in the film Alien, that "in space no-one can hear you
scream".The phone will play out several of the screams submitted by people online.
The test will monitor the durability of standard commercial components in space.
It will also test two new innovative propulsion systems.
The first - named Warp Drive (Water Alcohol Resisto-jet Propulsion De-orbit Re-entry Velocity Experiment) - uses the ejection of a water-alcohol mixture to provide thrust.
The second technology is pulsed plasma thrusters. These use an electric current to heat and evaporate a material, producing a charged gas that can then be accelerated in one direction in a magnetic field to push the satellite in the other direction.
'Fantastic achievement'
The mission will see the so-called "smartphone-sat" - a world first - orbit the Earth for six months."This mission is a fantastic achievement and a great tribute to the hard work of the engineers involved," said Sir Martin Sweeting, director of SSC, and also executive chairman of SSTL.
At first, the Strand-1 satellite will be controlled by a standard onboard computer, but in phase two of the mission, a Google Nexus phone will take the reins - equipped with a number of special apps.
One of them, iTesa, is to record the magnitude of the magnetic field around the phone during orbit.
The 360 app will take pictures using the phone's built-in five megapixel camera, and will act as a method of establishing the satellite's position.
Images captured by the app will be posted on Facebook.
