Astronaut safety in focus as undergraduates take on space station challenge
Two teams of Clemson University undergraduates are creating devices that could smooth sharp edges on the outside of the International Space Station, making spacewalks safer for astronauts.
The two Clemson teams were among 25 across the nation to advance to the testing phase in NASA’s Micro-g NExT program. Each will have a chance this spring to test their devices in the Neutral Buoyancy Laboratory, a 6.2-million gallon pool at Johnson Space Center in Houston where astronauts train for spacewalks.
“The tools designed for Micro-g NExT address an authentic, current space exploration challenge,” according to NASA. “Upon successful testing, these student-designed tools have the possibility of being used for future NASA exploration missions.”
Both Clemson teams, Team B-Unique and Tune Squad, are addressing the same challenge.
Handrails used by astronauts on the outside of the International Space Station can develop sharp edges when they get dinged by micrometeoroids and orbital debris. The sharp edges can be dangerous because they could cut part of the spacesuit, particularly the gloves.
Team B-Unique is developing a device it is calling the Cheese Grater that would roll along the handrails to detect and repair sharp edges. Tune Squad’s device, called Edge B’ Gone, would use pneumatic cylinders to clamp onto the handrails and then use rollers to flatten the sharp edges.
The teams started by brainstorming in the second week of the school year and then came up with proposals. They work on their prototypes in the CEDAR lab in the Fluor Daniel Engineering Innovation Building.
Melanie Hedge, a sophomore majoring in bioengineering, is the team lead for Team B-Unique. Sam Borel, a sophomore chemical engineering major, is the team lead for the Tune Squad.
Team B-Unique consists of Hedge, Morgan Perras, Stephen Miller, William Oldham and Dylan Cassell. Tune Squad’s members are Borel, Nick Spivey, William Pierce, Michael Furgeson , Kimberly Henning, and Meredith Sutton.
The teams are advised by graduate student Hallie Stidham and Professor Joshua Summers, both of the Department of Mechanical Engineering.
