With James Webb Space Telescope’s huge sunshield in place, focus shifts to big mirrors

We can all take a deep breath before the James Webb Space Telescope’s next major deployment. On Tuesday (Jan. 4), Webb finished bringing its huge, five-layer sunshield up to the proper tension, wrapping up the most complex and tricky operation of the $10 billion observatory’s lengthy deployment phase.  The mission team can therefore now turn … Read more

James Webb Space Telescope completes tricky sunshield deployment

The James Webb Space Telescope has successfully deployed all five layers of its tennis-court-sized sunshield, a prerequisite for the telescope’s science operations and the most nerve-wracking part of its risky deployment. The challenging procedure, which required careful tensioning of each of the five hair-thin layers of the elaborate sunshield structure was a seamless success today … Read more

JWST: James Webb Space Telescope is carrying out its most critical manoeuvre

The massive space telescope, which launched on Christmas Day, is in the process of deploying its sunshield. If anything goes wrong, it could endanger the entire mission Space 4 January 2022 By Alex Wilkins A final glimpse of the James Webb Space Telescope Arianespace, ESA, NASA, CSA, CNES After a nail-biting launch on Christmas Day, … Read more

Things are getting tense for NASA’s James Webb Space Telescope, literally

The tension is rising for NASA’s James Webb Space Telescope.  On Monday (Jan. 3), James Webb Space Telescope controllers began tightening the tension on its massive sunshield, a five-layer shield the size of a tennis court designed to keep the $10 billion observatory cool enough for science.  The task is the final step in unfolding … Read more

NASA delays tightening James Webb Space Telescope sunshield to study power system

NASA personnel are spending the day studying the power subsystem of the massive James Webb Space Telescope to ensure the observatory is ready to execute a key procedure: tensioning its vast sunshield. The Webb space telescope, which launched on Dec. 25, is conducting a month-long deployment procedure necessary to prepare the telescope to gather data. … Read more

James Webb Space Telescope team taking a rest day before sunshield tensioning begins

To celebrate the new year, consider taking a day to rest. That’s what the team managing the complicated process of deploying the James Webb Space Telescope are doing, taking Saturday (Jan. 1) off. Work will resume on Sunday (Jan. 2), according to an agency update. The pause comes after a long day on Friday (Dec. … Read more

James Webb Space Telescope unfurls massive sunshield in major deployment milestone

One of the James Webb Space Telescope’s most nail-biting deployment steps is safely in the books. The $10 billion observatory unfurled its huge sunshield on Friday (Dec. 31), carefully unfolding the five-layer structure by sequentially deploying two booms. “Shine bright like a diamond. With the successful deployment of our right sunshield mid-boom, or ‘arm,’ Webb’s … Read more

Why the James Webb Space Telescope’s sunshield deployment takes so long

NASA’s James Webb Space Telescope is three days into the deployment of its massive sunshield — and it still has about three days to go. The $10 billion Webb launched on Christmas Day (Dec. 25) to seek out heat signals from the early universe. To pick up these faint signals, the observatory’s optics and instruments must … Read more

There Was a Major Unexpected Benefit to James Webb’s Christmas Launch

After a detailed analysis of where the James Webb Space Telescope is now (29 December 2021) and how it got there, NASA determined the observatory should have enough propellant to operate in space for significantly more than 10 years in space.   Webb’s mission lifetime was designed to be at least 5-1/2 years, and mission … Read more
