NASA’s next big space telescope set up for an explosion from French Guiana

The James Webb Space Telescope is a NASA device designed to give humanity the first glimpse of the infant universe that existed when the earliest galaxies were thought to have formed, from the northeastern coast of South America. It was scheduled to be launched on Saturday.

Welcomed by NASA as the best space science observatory for the next decade, the innovative $ 9 billion infrared telescope is ready to explode from European Space at 7:20 am Eastern Standard Time (1220 GMT). Bundled in the cargo compartment of the Ariane 5 rocket. The launch base of the Agency (ESA) in Guiana, France.

If everything goes according to plan, the £ 14,000 instrument, which deploys to about the size of a tennis court, will be released from a French rocket after a 26-minute ride in space.

The following month, the Webb Telescope will coast to its destination in a solar orbit about one million miles from Earth. This is about four times the distance of the moon. Webb’s special orbital path maintains a constant alignment with the Earth as the planet and telescope orbit the Sun in tandem.

By comparison, Webb’s 30-year-old predecessor, the Hubble Space Telescope, orbits the Earth itself 340 miles away, moving in and out of the shadows of the planet every 90 minutes.

For most of NASA’s formation in the 1960s, the Webb, named after NASA’s chief, is about 100 times more sensitive than Hubble, significantly changing scientists’ understanding of the universe and our position within it. Is expected.

Hubble operates primarily at wavelengths of light and ultraviolet, while Webb displays the universe primarily in the infrared spectrum, allowing us to look into clouds of gas and dust where stars are born.

Space history lesson

The primary mirror of the new telescope is made up of 18 hexagonal segments of gold-coated beryllium metal, which has a much larger focusing area than Hubble and other telescopes, so it is far away. You can observe objects at a distance.

According to astronomers, you can get a glimpse of a universe you’ve never seen before. It is the theoretical flash point that began the observable expansion of the universe just 100 million years after the Big Bang, estimated 13.8 billion years ago.

Hubble’s view dates back to about 400 million years after the Big Bang. This is the period immediately after the formation of the first cluster of galaxies, stars, gases, and other interstellar media.

Astronomers are keen to study supermassive black holes, which are thought to occupy the center of distant galaxies, apart from more clearly examining the formation of the earliest stars and galaxies in the universe.

Webb’s equipment also searches for evidence of life-supporting atmospheres around a number of newly recorded extrasolar planets (celestial bodies orbiting distant stars), and Mars and Saturn’s A Moon of Ice Titan. Ideal for observing a world far closer to home.

The telescope is an international collaboration led by NASA in collaboration with space agencies in Europe and Canada. Northrop Grumman Corp was the prime contractor. The Arianespace rocket is part of Europe’s contribution.

Webb was developed at a cost of $ 8.8 billion and has an operating cost Total price tag To about $ 9.66 billion, much higher than NASA’s previous plans for a 2011 launch.

Astronomical manipulation of the telescope, managed by the Space Telescope Science Institute in Baltimore, is scheduled to begin in the summer of 2022 after approximately six months of adjustment and calibration of Webb’s mirrors and equipment. The Space Observatory is designed to last up to 10 years.
