+ - NASA revamps historic 9 million lb Mars antenna->

coondoggie writes: The ubiquitous antenna was all the buzz last week as Apple tried to squelch the latest glitch in its popular iPhone. But those antenna issues have nothing on the renovations NASA is taking on to reinvigorate its 70-meter-wide (230-foot-wide) "Mars antenna.” The antenna, a key cog in NASA’s Deep Space Network, needs about $1.25M worth of what NASA calls major, delicate surgery. The revamp calls for lifting the antenna — about 4 million kilograms (9 million pounds) of finely tuned scientific instruments – to a height of about 5 millimeters (0.2 inches) so workers can replace the steel runner, walls and supporting grout.
