NASA’s James Webb Space Telescope, (JWST), has completed a key milestone during its “29 days on edge” journey to reach its solar orbit destination. It began the unfoldment of its huge sunshield.
The US space agency said that the telescope was “blooming in space like a flower,” and added that this is the beginning of #UnfoldTheUniverse’s major phase: the deployment of our sunshield.
After the telescope (a joint NASA-ESA/CSA project) passed the moon, the sunlight began to emerge.
Slowly, the $10 billion stargazer is preparing for its first observations. It will begin in June 2022 by slowly unfolding its antenna and sunshield.
The telescope launched on Christmas Day from French Guiana, on an Ariane 5 rocket provided by the European Space Agency, following months of delays to the launch.
It’s currently at 40 percent of the way to the Lagrangian point L2, an area where the Earth and sun are in balanced gravity. There, it will spend over a decade exploring infrared.
The sunshield will be deployed gradually over the next five days of the journey, which, once fully open will be about the same size as a tennis court, and protect Webb’s optics from the sun.
Over the course of five days, the sunshield will gradually be installed. Once fully opened, it will measure approximately the same as a tennis court and will protect Webb from the sun.
NASA’s James Webb Space Telescope, (JWST), flew past the moon this morning. It traveled at over 2,400 miles an hour while continuing its one million-mile journey to solar orbit.
NASA describes the first step in preparing sunshield preparation as unfolding the pallet. This is similar to a cake stand and can hold five layers.
NASA announced that NASA had deployed the back sunshield pallet, making it clear that the gigantic observatory is already beginning to form.
You will find a cold and hot side to your telescope. This hot side is behind the sunshield and can reach temperatures as high as 185°F.
While the telescope is holding its science instruments and mirrors at 388 degrees Fahrenheit the cool side will remain there.
The moon’s attitude was reached at 01:20 GMT Tuesday morning. It continued its journey by completing its second burn.
NASA tweeted, “It’s been quite a hectic evening! We just completed our second burn. #NASAWebb passed the altitude at the Moon, continuing its cruise to the 2nd Lagrange point for #UnfoldTheUniverse.
This space telescope will replace Hubble’s 30-year-old companion. It is approximately 100 times more sensitive that Hubble but it will continue to run with Hubble for as long as Hubble is operational.
Astronomers anticipate the JWST’s ‘profoundly transformed’ understanding of the universe. This includes being able look at the atmosphere of stars and planets.
NASAMoon tweeted: “We felt like we were flying!” You are kidding, but we wish you all the best on your remaining journey to L2.
NASA shared the following tweet from NASAWebb: “Thanks @NASAMoon!” We’ll be sure to send you and all the wonderful folks on @NASAEarth a postcard when we reach our destination.’
The second burn was to do a mid-course correction and fine-tune the path to the L2 points. This is just one of the three plans for this journey.
It made its first burn on Christmas Day shortly after it launched. This allowed it to adjust to its course by burning off some fuel.
NASA tweeted: “One of the interesting aspects about #NASAWebb’s launch and burns was that we always aim a little lower.”
Webb’s thrusters cannot push Webb toward the sun. They can only move Webb away. Launch and these burns were designed to avoid Webb drifting off.
NASAMoon said that JWST reached lunar elevation on its journey to L2 after NASAMoon sent a tweet saying “we felt a breeze”.
NASAWebb offered to send Webb a postcard and NASAEarth reminded Webb to “phone home”.
On December 26, the space telescope launched its gimbaled assembly.
Webb plans to use the dish antenna with high data rate to send 28.6Gb back to Earth at least twice per day, including images from observation.
It took about one hour for the antenna to be released.
NASA confirmed separately that both the strain gauges and temperature sensors on the telescope had been successfully activated.
NASA announced that Webb engineers now have access to strain and temperature data for monitoring Webb’s structural and thermomechanical systems.
On Christmas Day, the telescope was launched from space aboard an Ariane 5 rocket.
It was a long time After taking off from French Guiana’s European Spaceport facility, the rocket took off into the sky over the Atlantic Ocean.
As the rocket lifted its boosters, it soared at an altitude 870 miles (1 398 km) before finally releasing the telescope and embarking on its journey.
NASA spokesperson said that Webb would usher in an era of new astronomy with its launch.

After an excellent flight through the Earth’s atmosphere into space, James Webb’s telescope module was released from its body by the Ariane 5 rocket. It had been blasting it upwards. Mission control at Kourou in French Guiana cheered.
NASA’s James Webb Space Telescope was launched successfully by NASA after many years of delay and planning.
Pictures from the European Space Agency’s Spaceport facility in French Guiana show the Webb telescope module atop an Ariane 5 rocket blasting off from Earth at 7.20AM ET (12.00PM GMT) on its million-mile journey into solar orbit
The Ariane 5 rocket was used to launch the most powerful satellite in the world, the Ariane 5, which took off from the Earth at 7.20am.
Seven seconds of engine engagement by the Ariane 5 rocket were required to warm up the spaceship before it took off. This actually occurred at 7.20 AM ET
As the telescope and planet circle the sun together, the new telescope will be able to keep its orbital path in perfect alignment with Earth.
It is an international partnership led by NASA, in collaboration with Canadian and European satellite agencies.
After years of delay in its construction, it was hit with months-long delays at launch. The first launch date for the rocket was set to take place in 2007.
Last year, the launch was rescheduled to Christmas Eve. Then it was moved to December 25 with a window for launch between 07:20 ET (12.20 GMT) and 07.52 ET (12.52 GMT).
It was then loaded onto an Ariane 5 rocket fairing and transported to the French Guiana European Space Agency launch site.
Officials have confirmed that Ariane 5 is in excellent condition and that there was no problem with the launch due to the beginning of French Guiana’s wet season.
James Web Telescope was also called JWST, or Webb. Its construction began in 1996. NASA’s budget for completion of the project was only $500 million.
Although the agency had been scheduled to launch it in 2007, cost overruns, technical problems and other issues caused a significant redesign that resulted in its first delay.
In 2016, construction of the telescope was finished, allowing for testing. However, two years later, the huge sunshield fell during a practice session. This led to another postponement.

Months of delay in launch have caused the telescope to lose its prime launch date of 2007 after years of construction delays.
The coronavirus pandemic of 2020 created additional delays.
James Webb arrived in French Guiana on October 20, 2021 after a 16-day voyage aboard the MN Colibri. He was then removed from his transport container before launch preparations.
NASA says that the first fuelling operation began November 25, and took around 10 days.
As the rocket was preparing to launch on December 24, the Guiana Space Center secured the space telescope on the Ariane 5 rocket.
Mother Nature was not pleased with the plan and she moved on to another day.
It was then loaded onto an Ariane 5 rocket fairing and transported to launch site at French Guiana’s European Space Agency Facility.
The rocket is large enough that it could be folded origami style to fit inside the rocket. It will then unfold ‘like Transformers’ in space and spread its mirrors to gather light from deep within the history of our universe.
Mark McCaughrean (ESA Webb Interdisciplinary Scientist) has waited for more than 20 year to be able to collect data with Webb.
MailOnline asked him if he was nervous about the rocket’s launch. It had been successfully tested, simulated, and ready to go, and he believed in engineers.
“Launch can be a concern, you’ve placed an expensive piece on a barely guided blast, but that is exactly what we do, the Ariane 5 being a workhorse,” he stated.
NASA says the telescope was so big that it had to be folded in origami style to fit inside the rocket. NASA predicts the telescope will unfold in space ‘like Transformers,’ spreading out its mirrors and collecting light from deep within the history of our universe.
Webb is already years late when he left Earth to go to space. He will be looking back at the very beginning of time to see the moment the galaxies and stars formed.
Webb is primarily an infrared telescope. It has a greater spectrum than Hubble’s and operates in a more solar orbit. The rocket launched from French Guiana’s Kourou on an Ariane 5 European Space Agency rocket.
The launch went according to plan. However, the scary part for many astronomers is coming in the next few weeks when the observatory will reach its solar orbit.
Webb will travel to an orbit about one million miles away from Earth and undergo six months of commissioning in space – including unfolding its mirrors and sunshield, cooling down, aligning and calibrating.
NASA claims that this will allow scientists to observe the Universe from around the globe.
Named after James E. Webb (American government official, who served as NASA administrator from 1961 through 1968) and was an integral part of the Apollo program.
NASA’s decision to name the device after him was a controversial one – he has been accused of homophobia since his passing in 1992 due to his role in the 1963 firing of a gay NASA employee.
NASA said that the James Webb Telescope would not be renamed before its December launch, in spite of a petition opposing it.
Webb was 85 years old when he died in 1992. Webb took over from John F. Kennedy’s request in 1961.
From 1968 to 1968, he was the head of the agency and was key in the Apollo programmes that saw Buzz Aldrin and Neil Armstrong walk on the Moon the year after he left.
Webb, a primary infrared telescope will provide a greater view of the Earth than Hubble. Webb can also operate in a more distant solar orbit.
McCaughrean stated that JWST reduces the number of objects visible. This is primarily because McCaughrean’s telescope, which has a temperature of -230 Celsius, doesn’t emit any infrared light, meaning astronomers can’t ‘fight against’ the infrared emitted by Earth.
Webb can take photos ten times sharper and hundreds times more detailed than Hubble’s, and he will also be able to zoom in on them.
Hubble can be found at 340 miles from the Earth’s surface. Webb, however, will be more than a million miles away.
James Web Telescope was also called JWST, or Webb. Its construction began in 1996. NASA did not have a budget of $500 million to complete the project at that time.
The telescope will observe the Universe in the near-infrared and mid-infrared – at wavelengths longer than visible light. The telescope is outfitted with state-of the-art cameras and spectrographs as well as coronagraphs.
Ohio State University researchers claim that James Webb will find signs of alien existence on distant planets within five years after it comes online.
Caprice Phillips is a graduate student who calculated it can detect ammonia made by living creatures on gas dwarf planets within a matter of orbits.
James Webb Space Telescope was described by some as a “time machine”, which could aid in unravelling the mysteries of our universe. Remote objects emit light that comes from farther back, and this is what James Webb Space Telescope claims to be.
It will allow you to see back the first galaxies formed in the beginning universe over 13.5 billion years ago.

After its blast off, 28 minutes later the James Webb was released from its launch vehicle. It began “the most complex series of deployments in one space mission”
The telescope will be able to observe stars and exoplanets as well as the planets and moons in our solar system.
The potential of the Webb telescope has inspired thousands of astronomers all over the globe.
Webb is being used by one group of scientists to observe the ‘cosmic dawn’, the moment when the stars of the universe first saw light billions of year ago.
James Webb’s lifespan is five years. NASA however hopes that it will last a decade. NASA has already seen Hubble outlive its life span by many decades. But unlike Hubble, James Webb cannot be fixed.
The telescope will observe the Universe in the near-infrared and mid-infrared – at wavelengths longer than visible light. The telescope is outfitted with state-of the-art cameras and spectrographs as well as coronagraphs.
ESA will procure the Ariane 5 rocket and launch services. ESA also contributes the NIRSpec instrument as well as a portion of the MIRI Instrument.
It will take test images, not of any specific object. The camera could even copy Hubble to capture an image of Jupiter and make its first observations.
Exoplanets will receive up to 30% of the initial year’s observations. This is to examine their size, orbit and atmosphere in search for alien life.
