Every part of the James Webb Space Telescope’s (JWST’s) deployment is nerve-wracking, but some of the most nail-biting moments will happen on New Year’s Eve and New Year’s Day.
But starting on December 31 comes the task that is among the most worrisome: unfolding the giant sunshield. The enormous sunshield is about 70 by 47 feet (21 by 14 meters) when deployed, or approximately the size of a tennis court.
If you ask a physicist like me to explain how the world works, my lazy answer might be: “It follows the Standard Model.”
The Standard Model explains the fundamental physics of how the universe works. It has endured over 50 trips around the sun despite experimental physicists constantly probing for cracks in the model’s foundations.
With few exceptions, it has stood up to this scrutiny, passing experimental test after experimental test with flying colors. But this wildly successful model has conceptual gaps that suggest there is a bit more to be learned about how the universe works.

Iran’s space launch on Thursday has failed to put its three payloads into orbit after the rocket was unable to reach the required speed, a defence ministry spokesman said in remarks carried on state television.
The attempted launch, which came as indirect United States-Iran talks take place in Austria to try to salvage a 2015 nuclear deal, drew criticism from the US, Germany and France.
“For a payload to enter orbit, it needs to reach speeds above 7,600 [metres per second]. We reached 7,350,” the spokesman, Ahmad Hosseini, said in a documentary about the launch vehicle broadcast on state TV and posted online on Friday.
🌱 🤓 This week I helped with the latest experiment going on in the International Space Station plant habitat which cultivates several cotton genotypes. Each of these petri dishes contains undifferentiated masses of cotton cells known as a calli. Cotton is highly resistant to the process of plant regeneration, making it difficult to engineer stable, reproducing plants that have specific or enhanced traits such as drought resistance. The investigation could provide a better understanding of this behavior and could ultimately improve our ability to grow crop plants on Earth and in space.

James Webb Space Telescope launched on Saturday, Dec 25 at 12:20 UTC from Guiana Space Centre. Webb Telescope liftoff aboard Ariane 5 rocket.
James Webb Space Telescope (JWST) is a space telescope being jointly developed by NASA, the European Space Agency, and the Canadian Space Agency. It is planned to succeed the Hubble Space Telescope as NASA’s Flagship astrophysics mission.
With revolutionary technology, Webb will observe a part of space and time never seen before, providing a wealth of amazing views into an era when the very first stars and galaxies formed–over 13.5 billion years ago.
Webb is NASA’s largest and most powerful space science telescope ever constructed. Webb’s enormous size and frigid operating temperature present extraordinary engineering challenges.
After launching from French Guiana, the observatory will travel to an orbit about one million miles away from Earth and undergo six months of commissioning in space—unfolding its mirrors, sunshield, and other smaller systems, cooling down, aligning, and calibrating.
