On May 4, Katalyst Space Technologies completed environmental tests of its LINK robotic servicing spacecraft at NASA's Goddard Space Flight Center in Greenbelt, Maryland. LINK will meet up with Swift and attempt to raise its orbit. "The Swift boost attempt is a fast, high-risk, high-reward mission," said John Van Eepoel, Swift's mission director at NASA Goddard.…
