Just weeks after the joy of launch, the James Webb Space Telescope is already in search of focus in space.
Engineers are starting alignment procedures for the recently unfolded 18-segment large golden mirror. The work will ultimately get these particular person reflectors working as a single focusing machine, NASA officers wrote in a blog update posted on Wednesday (Jan. 12).
The process started with engineers commanding 132 actuators that can transfer and place the primary mirror segments and the secondary mirror, simply to verify every thing was responded as anticipated. The workforce additionally ensured the actuators are working to information Webb’s positive steering mirror, which will probably be used throughout the picture stabilization course of.

The observatory workforce will spend about 10 days working to maneuver the mirror segments out of their launch alignments, with extra exact work persevering with past that point.
The aim is to get all of Webb’s items working as a single observatory in space, which will probably be important for the telescope’s ambitious agenda of telling us extra in regards to the early universe and the life historical past of varied objects which are part of it.
NASA estimates that each one advised, the alignment will take about three months, which ought to convey this work into mid-April so long as every thing runs to schedule. Webb launched on Dec. 25 and should have sufficient gasoline for 20 years of science due to the precision of the launch, however that each one depends upon the mirrors working correctly.
“Ground teams have now begun instructing the primary mirror segments and secondary mirror to move from their stowed-for-launch configuration, off of snubbers that kept them snug and safe from rattling from vibration,” NASA mentioned. “These movements will take at least ten days, after which engineers can begin the three-month process of aligning the segments to perform as a single mirror.”
Webb remains to be en path to a “parking spot” known as Earth-sun Lagrange Point 2 (L2) about 930,000 miles (1.5 million kilometers) away from our planet. It will make an engine firing on Jan. 23 to glide towards that zone.
The next-generation telescope should full about six months of commissioning actions, then will embark on a collection of early science packages this summer season, spanning every thing from finding out exoplanets to probing the start of the universe.
