NASA Revamps Historic 4-Million-kg Mars Antenna

Posted by Soulskill on from the we're-gonna-need-a-bigger-bumper dept.

coondoggie writes NASA is working on some difficult renovations to reinvigorate its 70-meter-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 of finely tuned scientific instruments — to a height of about 5 millimeters so workers can replace the steel runner, walls and supporting grout."

    We had to go through this with a 7 million kilogram antenna at the Green Bank Telescope:

    The original azimuth track wore down too quickly, apparently due to faulty materials, workmanship, etc. You can see photos of the scope rotating out of the way sections of the track could be replaced at a time.

    4 million kilograms; why can't we just use metric as it was intended?
