NASA’s new space telescope ‘hunky-dory’ after problems fixed

NASA’s new space telescope is on the verge of completing the riskiest part of its mission — unfolding and tightening a huge sunshade — after ground controllers fixed a pair of problems, officials said Monday.

The tennis court-size sunshield on the James Webb Space Telescope is now fully open and in the process of being stretched tight. The operation should be complete by Wednesday.
