NASA's James Webb Space Telescope Successfully Unfolds its Massive Mirror

NASA's James Webb Space Telescope successfully unfolds its massive mirror:

The team behind the recently launched James Webb Space Telescope successfully finished unfolding the instrument's distinctive golden mirror on Saturday, meaning the telescope is now fully deployed and is one step closer to sending back data about the universe's first galaxies.

"The successful completion of all of the Webb Space Telescope's deployments is historic," Webb's program director at NASA Headquarters, Gregory L. Robinson, said in a release. "This is the first time a NASA-led mission has ever attempted to complete a complex sequence to unfold an observatory in space – a remarkable feat for our team, NASA, and the world."

NASA and its partners, the European Space Agency and the Canadian Space Agency, began remotely unfolding the two wings of Webb's primary mirror on Friday and completed the task at about 10:15 a.m. PT Saturday, when the second wing latched into place.

Over the next six months, Webb is set to travel 1 million miles from Earth and begin sending back images of the universe that promise to serve up a new, unfiltered story of the cosmos. Not only will Webb teach us about hidden regions of space, it also has the power to prove whether we've correctly documented the events that happened right after the Big Bang.

Remarkably, NASA Has Completed Deployment of the Webb Space Telescope

Remarkably, NASA has completed deployment of the Webb space telescope:

But now that ultra complex heat shield is working. The temperature on the Sun-facing side of the telescope is 55 degrees Celsius [(131 °F)], or a very, very, very hot day in the Sahara desert . And already, the science instruments on the back side of the sunshield have cooled to -199 degrees Celsius[(-326.2 °F)], a temperature at which nitrogen is a liquid. They will yet cool further.

Work remains, of course. Webb still must traverse about 370,000 km to reach an orbit around a stable Lagrange point, L2. Scientists and engineers must check out and align the 18 primary mirror segments. Scientific instruments must be calibrated. But all of this work is somewhat more routine when it comes to science spacecraft. There are risks, to be sure, but these are mostly known risks.

We can therefore be reasonably confident now that Webb will, in fact, begin to make science observations this summer. We should, truly, be in awe.

    So why not fund me, say a trillion dollars a year, to do that priceless knowledge? I'm pretty sure, I can find new priceless knowledge with a few million dollars and the rest of that money, which is nothing, can be redirected more productively to the khallow pampering fund, which is something for me.

    There are basic entry level competencies to bid, khallow. I am sorry to inform you, in the opinion of the board, that your past publications on SoylentNews, and elsewhere, do not suggest you are capable of doing priceless knowledge. In fact, it seems you are always after priced knowledge, that would allow you to such up the the ultra rich class. Try Blue Orifice instead.

    That box is checked here. I got basic entry level competencies.

    the opinion of the board

    I'm the board. I got this. I just don't have that trillion dollars yet. Why do you hate science?

    As an aside, ari, you've granted me the game by allowing that some approaches appear more "capable" than others. It's merely a minor detail that approaches with better scientific return over their opportunity costs are more capable.

      Ari? We were talking about competencies, khallow. You fail again.
