UBC Snowstar, a team of UBC engineering physics students, unveiled their latest prototype of their solar-powered space elevator robot, set to compete in the 2007 NASA Beam Power Challenge.
Held in the Greater Salt Lake City Area, Utah, during Oct. 19-21, the NASA competition challenges entrants to design, build and race a space elevator "climber" capable of efficiently lifting a payload 400 feet (120 metres) straight up a cable using only power "beamed" from a remote source on the ground. Climbers must reach a minimum speed of 6.6 feet (two metres) per second to qualify.
UBC Snowstar has been featured in The New York Times and on CNN. They will compete with more than 20 international teams for the US $500,000 grand prize and an opportunity to revolutionize space technology. UBC is one of only two teams that have qualified to compete in all three NASA Beam Power Challenges, meeting performance benchmarks that double each year. For example, the 2006 competition required teams to lift a payload 200 feet (60 metres) at a minimum speed of 3.3 feet (one metre) per second.
"Currently, the cost of launching a space shuttle is so high partly due to the amount of fuel the shuttle carries in order to propel itself into space," says Snowstar team captain Damir Hot. "Using solar or other beamed power sources to efficiently fuel space vehicles could be the key to eventually providing space transport at significantly lower financial and environmental costs."
