James Webb Space Telescope sunshield tensioning full!

NASA has simply confirmed that the fifth and closing layer of the James Webb Space Telescope’s warmth protect has been efficiently tensioned, marking the top of the sunshield deployment work that started final week.

“This is an historic day,” NASA scientist Michelle Thaller stated throughout a stay webcast. “The first major phase of the deployment of the sunshield has been compete.”

Our wrap story on the occasion will probably be posted shortly.

NASA webcast for Webb sunshield tensioning

Update: NASA’s Webb sunshield tensioning webcast is underneath approach. Watch stay above for the vital milestone for the James Webb Space Telescope.

It’s Day 2 of sunshield tensioning for NASA’s James Webb Space Telescope and the space company will webcast stay views from Webb’s mission operations middle in Baltimore, Maryland at this time beginning at 9:30 a.m. EST (1430 GMT). You’ll be capable to watch that stay right here within the window above at begin time.

NASA didn’t state how lengthy the webcast will final, however the company does have one other occasion scheduled for 11:25 a.m. EST from the International Space Station, so it doubtless will not final past that. 

Webb’s sunshield tightening is the ultimate step within the intricate unfurling of the space telescope’s tennis court-sized protect to guard it from daylight and preserve it cool sufficient for science. It entails utilizing a collection of motors to place and tighten the 5 ultra-thin layers of Webb’s reflective sunshield. 

The course of started on Monday, Jan. 3, with Layer 1 tightening and was anticipated to finish as quickly as Wednesday, Jan. 5. However, NASA is approach forward of schedule. As of late Monday, three of the 5 sunshield layers have been efficiently tightened, the company said in an update on Twitter.

Webb space telescope in good well being, tensioning starting

NASA’s James Webb Space Telescope is in good well being and can start tensioning its large sunshield at this time, its mission crew stated at this time. 

In a media teleconference, NASA officers stated Webb will begin tightening the tension on the 1st layer of the five-layer sunshield on Webb at this time after two days of relaxation and energy system optimization. 

Two points occurred over the New Year’s Day vacation weekend.

First, Webb’s solar arrays weren’t producing as a lot energy as they might on account of their manufacturing facility settings. At no level was the space telescope in want of energy, however NASA rebalanced the arrays in order that they will now work at their peak effectivity. 

Second, the motors used to stress Webb’s sunshield weren’t staying cool sufficient as flight controllers most well-liked. They commanded Webb to alter its orientation in space in a approach that may preserve its motors cooler in the course of the deployment phase. 

With each of these fixes in, Webb seems to be doing properly in its deployment. 

The tensioning course of for Webb’s sunshield ought to take at the very least three days, NASA officers stated.

NASA to carry press convention on Webb deployment

NASA will maintain a media teleconference at 11:30 a.m. EST (1630 GMT) at this time, Jan. 3, and you’ll hearken to it stay right here, courtesy of NASA TV. You may also watch directly from NASA here.

This teleconference will replace the general public on the James Webb Space Telescope’s deployment after its sunshield was deployed on Dec. 31. 

NASA paused deployment actions on Saturday, Jan. 1, to offer its crew a relaxation. The crew then spent Sunday finding out Webb’s energy programs earlier than continuing with the ultimate steps for sunshield deployment.

James Webb Space Telescope stress may start at this time

After a day of delay, NASA James Webb Space Telescope flight controllers are anticipated to start the sunshield tightening course of on the brand new space observatory at this time, Jan. 3. 

The course of, which may take at the very least two days, was initially slated to start yesterday, however NASA opted to face down and as an alternative research Webb’s energy programs to verify they had been working correctly after per week in space. 

The sunshield tightening course of entails activating a collection of motors on Webb that may separate, after which tighten, the 5 layers of the space telescope’s gossamer sunshield, which is blocks out daylight from the infrared observatory’s delicate devices so it might probably higher research the universe.  — Tariq Malik

NASA delays Webb sunshield tensioning

NASA flight controllers have delayed at this time’s deliberate tensioning of the James Webb Space Telescope’s sunshield with a purpose to work on the observatory’s energy programs. 

“This will ensure Webb is in prime condition to begin the next major deployment step in its unfolding process,” NASA officers wrote in an update today (Jan. 2). 

Read our full story by Senior Writer Meghan Bartels.

The sunshield tensioning course of will now start no sooner than Monday, Jan. 3, and is anticipated to take at the very least two days. Flight controllers made the choice earlier at this time with a purpose to optimize the ability programs on the Webb space telescope.

“Specifically, the team is analyzing how the power subsystem is operating now that several of the major deployments have been completed,” NASA wrote within the replace. “Simultaneously, the deployments team is working to make sure motors that are key to the tensioning process are at the optimal temperatures prior to beginning that operation.”

Webb’s step-by-step deployment course of is designed in such a approach that it may be stopped and began alongside the best way as required, in accordance with NASA officers. The flight management crew needs to make use of some additional time to raised perceive how Webb is behaving in space, and the way it’s differing from simulations primarily based on laptop testing on the bottom.

“Nothing we can learn from simulations on the ground is as good as analyzing the observatory when it’s up and running,” stated Bill Ochs, NASA’s Webb undertaking supervisor on the Goddard Space Flight Center in Greenbelt, Maryland, stated within the replace. “Now is the time to take the opportunity to learn everything we can about its baseline operations. Then we will take the next steps.” — Tariq Malik

Webb ratchets up the strain at this time

It’s time to lift the strain on NASA’s James Webb Space Telescope. 

After taking New Year’s Day off on Saturday to relaxation up after an extended Friday night time unfolding Webb’s large sunshield, the mission crew goals to start tensioning the protect’s 5 layers at this time to lock them in place. 

It ought to take at the very least two full days to lock Webb’s sunshield in place, which marks the ultimate step in its weeklong deployment course of. The course of entails Webb separating the 5 layers of its sunshield, which unfolded in a single group after which tensioning them so they’re tightly secured for the space telescope’s lifetime. 

NASA expects to finish the sunshield tightening step on Monday, Jan. 3, and can then maintain a press teleconference to replace the general public on the space telescope’s standing. – Tariq Malik

Taking a relaxation day

The crew overseeing the deployment of the James Webb Space Telescope are taking at this time (Jan. 1) off, in accordance with a NASA assertion. Yesterday’s process, deploying the 2 booms that assist the width of the observatory’s large sunshield, ran later into the day than personnel had hoped. And the subsequent step is much more daunting: a two-day strategy of separating the 5 delicate layers of the huge sunshield.

That work will start tomorrow (Jan. 2), the assertion famous, and is anticipated to take two days to finish. Read more>

James Webb unfurls its sunshield!

The James Webb Space Telescope efficiently unfurled its large sunshield on Friday (Dec. 31), notching an enormous milestone in its lengthy and sophisticated deployment marketing campaign. Read our full story about it here.

The sunshield, which is able to assist preserve Webb’s optics and devices cool sufficient to detect faint warmth indicators from the early universe, unfolded by way of two “mid-booms,” which had been prolonged over two roughly three-hour stretches on Friday.

The increase extension actions had been delayed barely whereas Webb crew members checked to verify the sunshield’s protecting cowl had totally rolled up as wanted. But every thing labored out simply high quality.

“Today is an example of why we continue to say that we don’t think our deployment schedule might change, but that we expect it to change,” Keith Parrish, Webb observatory supervisor at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, stated in a blog post update Friday night.

“The team did what we had rehearsed for this kind of situation — stop, assess and move forward methodically with a plan,” Parrish stated. “We still have a long way to go with this whole deployment process.”

Next up is tensioning of the sunshield’s 5 layers, which could possibly be full as early as Sunday (Jan. 2). After that, the Webb crew will shift their focus to reflect deployment.

Sunshield midway unfurled!

The James Webb Space Telescope has efficiently deployed its sunshield port mid-boom, unfurling half of the large membranous construction.

“The deployment of the 5 telescoping segments of the mid-boom began around 1:30pm ET and reached full deployment at 4:49 pm,” mission crew members said via Twitter today (Dec. 31). “Webb’s deployment steps are all human-controlled, so the schedule can change. The team plans to deploy the starboard mid-boom tonight.”

There was certainly a schedule change at this time: The mid-boom deployments had been presupposed to occur earlier, however Webb’s handlers took additional time to verify the sunshield’s protecting cowl had totally rolled up as deliberate, mission crew members explained in another tweet.  

Sunshield deployment is likely one of the riskiest, most advanced actions the $10 billion observatory will carry out throughout its time in space. So preserve your fingers crossed that every thing goes properly tonight and over the weekend, when the crew plans to carry the deployed protect’s layers as much as the right stress.

James Webb Space Telescope to deploy sunshield booms

It’s an enormous day for the James Webb Space Telescope. 

Today is the day the large space observatory will deploy the 2 mid-booms on it port and starboard facet that may prolong its sunshield out to its full width. The port increase will probably be prolonged first, adopted by the starboard increase. Motors will drive each occasions. 

Each mid-boom will deploy with its 5 sunshield membrane layers connected. If it goes easily, Webb will spend the subsequent two days tightening the strain of the sunshield so it isn’t unfastened. 

Wondering why it takes so many steps to deploy Webb’s sunshield? Our Senior Writer Mike Wall has the full story here today.

Webb deploys flab, removes sunshield covers

NASA’s James Webb Space Telescope efficiently accomplished its two vital deployments for at this time, the space company introduced. 

In back-to-back updates, NASA officers confirmed that the Webb space telescope efficiently deployed its aft momentum flap and retracted the protecting membrane covers on its gossamer sunshield, a serious step within the weeklong work to unfurl the protect. 

Read the full story from Senior Writer Chelsea Gohd here.

The membrane covers protected Webb’s sunshield, which will probably be as giant as a tennis courtroom when deployed, throughout launch. You can see an animation of how the duvet retraction went in space above. 

Here’s a close-up graphic beneath of the aft momentum flap, which is designed to regular Webb towards the push of solar wind towards its large sunshield. — Tariq Malik

2 deployment steps for Webb telescope at this time

It’s been 5 days since NASA’s James Webb Space Telescope launched into space on the observatory has two steps deliberate for at this time to proceed its ultra-complicated deployment. 

Today, Webb is anticipated to unfold a aft momentum flap, a three-panel construction on the backside rear of the telescope designed to offset among the strain from the solar wind on Webb’s large sunshield. The flap ought to assist Webb preserve gasoline throughout its mission life because it limits the additional push on the telescope from the solar wind.

Later, Webb is anticipated to retract the sunshield membrane covers which were defending its skinny sunshield layers since launch. The step would require a collection of launch units to be activated that may then retract and roll up the membrane covers (two per sunshield pallet, fore and aft) to uncover the sunshield itself. 

When deployed, the five-layer sunshield will probably be concerning the measurement of a tennis courtroom. But there are 50 distinct steps to get it into place.
