Robert Staehle of JPL gave a presentation on Interplanetary CubeSats at NASA’s Institute of Advanced Concepts On March 28. The interplanetary CubeSat idea is rapidly catching on, as demonstrated by the Interplanetary CubeSat Workshop scheduled to take place at MIT on May 29-30 with NASA Chief Technologist Mason Peck as keynote speaker.

The interplanetary CubeSat concept is evolving rapidly. Staehle assumes that solar sails are arequired technology for propulsion. Another option has already emerged, however. The Microsystems for Space Technologies Laboratory at the École Polytechnique Fédérale de Lausanne’ has created a small ion engine for CubeSat-sized payloads. Theion drive weighs only 200 g including enough propellant to send a CubeSat from Earth orbit to the Moon or Mars
Planetary missions may soon be within reach of citizen scientists. Just getting a CubeSat into Earth orbit remains a problem, though. NASA’s Nano-Satellite Launch Challenge prize may help. A number of companies are already working on innovative solutions to the problem, including Premiere Space Systems (Nanolaunch) and XCOR Aerospace.
