Nasa begins process of bringing new space telescope into focus

Nasa on Wednesday embarked on a months-long, painstaking process of bringing its newly launched James Webb Space Telescope into focus, a task due for completion in time for the revolutionary eye in the sky to begin peering into the cosmos by early summer.

Mission control engineers at the Space Telescope Science Institute in Baltimore began by sending their initial commands to tiny motors called actuators that slowly position and fine-tune the telescope's principal mirror.
