NASA resurrects Voyager 1 thrusters after 20 years
NASA engineers
have miraculously revived the Voyager 1 interstellar probe's backup
thrusters - components that hadn't been used since 2004 and were long
considered fully defunct. This remarkable feat became necessary because
the spacecraft's primary thrusters, which control its orientation, have
been degrading due to residue buildup. If its thrusters fail completely,
Voyager 1 could lose its ability to point its antenna toward Earth,
therefore cutting off communication with Earth after nearly 50 years of
operation.
