STS-37 crewmembers work with CETA during EVA training in JSC's WETF

S89-46985 (October 1989) --- Astronauts Jerry L Ross and Jerome (Jay) Apt, STS-37 mission specialists, practice a spacewalk they will perform on that flight. The experiment uses an electrically powered version of the Crew and Equipment Translation Aid (CETA), a type of railroad handcart planned as a spacewalker's transportation system along the truss of Space Station Freedom. Apt is pulling Ross along to test the cart's ability to carry a person plus cargo.
