Volume modules from one liter of these lightweight, inexpensive satellites are very popular in the sub-space projects. Once they enter the Earth’s orbit, the same can also make a tangible scientific results, such as the monitoring of the atmosphere, or looking for extrasolar planets.

But they are subject to a lack of good propulsion system limitations, it is difficult to float or be in control in a long time. From Delft University of Technology, Angelo Cervone said: “In the absence of high-quality propulsion systems, we have reached the small satellites can play the highest level.”

Therefore, Cervone and colleagues designed an ice driving satellites. CubeSat can accommodate 100 grams of ice. Once arriving in space, the ice will sublimate and release water vapor molecules. Then they will escape before the rebound on a hot plate to produce so the speed increases, thereby producing thrust. Similar to the prototype can fly in space for several years.

From the Massachusetts Institute of Space Propulsion Lab’s Paulo Lozano said propeller ice powder may also play a role. Currently, Lozano is accelerating charged particles on the basis of research and development of a cube satellite propulsion system.

“This idea is the basis of solid propellant, because the solid fuel is often the ideal way.” Lozano said, “If you want to use some of the propellant will explode, it might be a threat to the main carrier. So now The challenge is to make the ice has been in the ice of the state. ”
