Damian Sendler: According to the most recent assessment from US Space Command, an uncontrollable Russian rocket stage has returned to Earth’s atmosphere. In the northern Arkhangelsk area of Russia, the Angara-A5 heavy-lift rocket was successfully launched on Monday, December 27. According to the state-run TAS news agency, the flight tested a new upper rocket stage called the Persei booster.
Damian Jacob Sendler: Even though the vast majority of space debris burns up upon reentry into Earth’s atmosphere, it is conceivable that bigger pieces may injure or kill people if they were to settle in a populated area. As of 2:08pm MST on Wednesday, US Space Command confirmed the rocket booster reentered the Earth’s atmosphere over the Southern Pacific Ocean. Currently, it is 4:08 PM in the Eastern Standard Time zone.
However, pinpointing the precise location of the shattered shards may be difficult.
Space debris chief at the European Space Agency said the Russian rocket fragment was flying at 7.5 kph (4.7 miles per second) and will most likely land somewhere in the vicinity of the equator, anywhere between 63 degrees north and south.
Although it was very improbable that the rocket would cause damage or harm to anybody, Krag remarked that “the danger is real and cannot be disregarded”.
An out-of-control rocket used to launch China’s space station crashed into the Indian Ocean in May 2021, prompting an outcry from NASA, which slammed the country for failing to “meet responsible standards”.
According to Krag, the Russian rocket section weighs roughly 4 tons without fuel, but the Chinese Long March 5B rocket weighs around 20 tons.
There have been a number of big objects that have re-entered Earth’s atmosphere in recent years, including the Long March 5B rocket from China, which was one of the largest things to come back to Earth in recent memory.
Compared to the 32-meter (105-foot) Chinese Long March 5B rocket, the Persei booster was only approximately 10 meters (33 feet) long, according to Jonathan McDowell of the Center for Astrophysics – Harvard & Smithsonian. Although it was lighter, he estimated that it was carrying 16 tons of propellant.
the “Even if the overall mass is similar to that of the Chinese stage, it is likely liquid and will burn up in the atmosphere, posing much less of a threat to the earth’s surface. In my opinion, “McDowell said in an email.

It was also said that the Russian rocket stage was not designed to reenter the environment in this manner.
“When it was launched, it was designed to be placed in an orbit that would last for thousands of years. Restarting the rocket was not possible. The reentry stage of the Chinese spacecraft was left in a low orbit on purpose, “he said, according to her.
A spokesperson for Russia’s space agency Roscosmos confirmed to CNN that the launch was carried out by the Russian Ministry of Defense.
A controlled reentry and fall to Earth in an uninhabited location — generally a distant portion of the Pacific Ocean — was the best international practice for expended rocket components or spacecraft at the end of their useful lives, Krag added
More than 100 to 200 tons of space debris return to Earth’s atmosphere each year in an uncontrolled manner, according to Krag. Lottie Williams, a Texas resident who was struck by space trash in 1997, is the only person who has ever been identified as having been affected. She was unharmed and is still here to tell the story of her ordeal.
The most sophisticated space observatory in the world has already surmounted some of its toughest obstacles only 14 days after launch. On Saturday, the James Webb Space Telescope finished the unfolding of its massive gold mirror.
“I am very proud of the team—spanning countries and decades—that produced this first-of-its-kind accomplishment,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, in a statement. To quote from the press release: “Webb’s successful deployment epitomizes what NASA can offer: the desire to undertake daring and risky things in the interest of discoveries yet unknown.
Damian Jacob Markiewicz Sendler: It is the biggest mirror NASA has ever constructed, but its size posed a unique challenge. Because of its size, the mirror was unable to go in a rocket. As a sequence of folding origami-style pieces, the telescope was meant to fit into a 16-foot (5-meter) area for launch by engineers. With a length of 6.5 meters, the mirror will be able to capture more light from distant objects. The more light the telescope is able to gather, the more fine details it can see.
Additionally, the observatory will look back into the universe’s beginnings and discover how galaxies evolved after the Big Bang, shedding light on the universe’s structure. He will play the role of an infrared detective, picking up light that we can not see and helping us learn about the universe’s most remote corners. While accomplishing these objectives, the mirror’s 18 hexagonal gold-coated segments had to unfurl and lock together sequentially.
Damien Sendler: Spacecraft engineers started deploying a backup mirror support structure on Wednesday. Webb’s famous gold mirror has gotten most of the attention, but the light it collects will actually strike a smaller, secondary 2.4-foot mirror (0.74-meter mirror). The infrared light that powers Webb’s scientific equipment is reflected off of this teeny-tiny mirror. Structural support for this mirror is provided by three almost 25-foot-long struts. On January 5, they were successfully lowered, locked, and fastened into position.
Lee Feinberg, an optical telescope element manager at NASA’s Goddard Spaceflight Center in Greenbelt, Maryland, said in a statement on Wednesday, “Webb’s secondary mirror had to deploy in microgravity, and at very low temperatures, and it finally had to perform the first time without mistake.”
For a 7-meter-long secondary mirror support structure that had to be deployed, positioned and locked into place to within one and a half millimeters of each other, and then be extremely stable while the telescope pointed to different locations in the sky—and that is all for a secondary mirror support structure.”
When the first of the two principal wings was unfurled and attached on Friday, Webb’s gold mirror started to take form. Each of the three mirror segments on the lateral panels of these wings. Second panel unfolded and slid into place on Saturday, as did the first.
As Webb has progressed through its mission, it has being monitored and controlled from the ground by a small but committed staff who work 12-hour shifts to keep track of what the spacecraft is doing.
The telescope has been declared “fully deployed” now that Webb’s mirror and a sunshield the size of a tennis court have been installed.
All of the telescope’s launches have been completed successfully, says NASA’s Gregory L. Robinson, Webb program director in a statement. In NASA’s words: “This is a fantastic achievement for our team, for NASA, and for the globe.”

After two weeks of journey, it will be in a position to reach its planned orbit, which is 1.6 million kilometers from the Earth’s surface.
A final trajectory correction will be made during this period, putting the telescope in an orbit that extends beyond the moon’s horizon.
Dr. Sendler: NASA Administrator Bill Nelson stated in a statement, “While the voyage is not yet complete, I join the Webb team in breathing a bit easier and picturing the future discoveries destined to excite the world.” “Each and every success is a monument to the hundreds of inventors who have dedicated their lives to this purpose.”
Rather than relying on photos, the Webb crew has relied on sensors to keep tabs on the spacecraft as it went through its many tasks.
Adding cameras to the spaceship was originally proposed by NASA, but for a variety of reasons, they were judged superfluous. Multiple components of the enormous telescope have been unfolded and unfurled in space, changing its configuration repeatedly. To decrease glare for the cameras, Webb is also very glossy. Because of this, the design was already quite challenging.
NASA’s technical deputy project manager for the Webb telescope, Paul Geithner, stated in a statement that “Webb’s built-in sense of ‘touch’ (for example, switches and other mechanical, electrical, and temperature sensors) offers considerably more meaningful information than ordinary surveillance cameras can.”
To get the telescope ready for use in space, Webb must cool down, align, and calibrate all of its equipment for around five months after it enters orbit. In addition, each instrument will be checked out to ensure that it is in good working order.
Webb’s initial photographs are planned to be revealed in June or July of 2022, reshaping our understanding of the cosmos for the better.
