It’s happening! Engineers to deploy covers that will protect James Webb Telescope from Sun, Earth, Moon
As the James Webb Space Telescope cruises in space, NASA engineers will perform the most challenging task-deploying sun visors. During the launch of the telescope, engineers have loosened and rolled up the sunshade to protect the thin layer.
The deployment of the cover takes about an hour. It requires the team to use electricity to activate the release device, execute the command to roll the cover to a fixed position, and expose the sunshade film to the space for the first time. After covering, the next step will be to deploy the middle arm of the sunshade before continuing to tighten the sunshade.
The team completed the deployment of momentum flaps on the tail of the observatory on Thursday, which will help reduce fuel consumption. Engineers will use fuel consumption throughout Weber’s life cycle to help keep the observatory’s direction in orbit. “When sunlight’s photons hit the surface of a large sun visor, they put pressure on the sun visor. If not properly balanced, this solar pressure will cause the observatory’s rotation and must be accommodated by its reaction wheels. The rear momentum flap will Continue to navigate the pressure of these photons, balance the sun visor and keep the observatory stable,” NASA said in a blog update.

Nasa’s old map of Jupiter, which reminds many of dosa, has gone viral once more
Certain images or videos frequently resurface on the Internet, leaving people speechless. When those clips or pictures are shared again on one social media platform or another, they create a buzz. The National Aeronautics and Space Administration (Nasa) created and posted this image of a map of Jupiter online a few years ago. After being shared on Twitter, the image drew a lot of attention this time. And, as usual, the image made people think of dosa, a popular South Indian dish.
The image was shared by the Twitter account Latest in Space. “From the very bottom of Jupiter, I’m looking up. While tweeting the image, they wrote, “Seen by NASA Cassini.” The images from the Cassini spacecraft’s narrow-angle camera were used to create this out-of-this-world image, which is part of a coloured map series produced by the space agency.
The article was published a few days ago. The tweet has received nearly 20,000 likes since it was shared, and the number is growing. The tweet has been retweeted more than 2,000 times. Take a look at some of the comments to see how the image of Jupiter looks like dosa.
A Twitter user commented, “Looks like a designer dosa.” “When I rush to pick up a call, this is what happens to my dosa on the dosa pan,” one joked. “This is how my mother makes Dosa,” a third said. “Jupiter in the making,” wrote a fourth, along with a photo of someone preparing – you guessed it – dosa.
