The NASA telescope is set to launch on a million-mile journey

Kauro: The world’s most powerful space telescope is set to explode at its outpost 1.5 million kilometers (930,000 miles) from Earth on Saturday, after a delay due to technical hurdles.
James The web The space telescope, built in nearly three decades and billions of dollars, will land Earth from its Caro space center in French Guiana in its Ariane 5 rocket.
The launch, scheduled in a short window after 9:20 (1220 GMT), will send the telescope on a month-long journey into its remote orbit.
He hopes to find new clues that will help scientists understand more about its origins. The universe And Earth-like planets outside our solar system.
Named after the former NASA The director follows in the footsteps of the legendary Hubble – but intends to show humans what the universe looked like near its birth about 14 billion years ago.
Speaking on social media, co-founder of the web project John Mather Described the unprecedented sensitivity of the telescope.
“Can see the beetle’s heat signature at a distance from #JWST The moonHe said.
It takes a lot of energy to find the first galaxies that existed billions of years ago and the weak glow emitted by the first stars.
Telescopes are unequal in size and complexity.
Its mirror is 6.5 meters (21 feet) in diameter – three times the size of Hubble’s mirror – and is made up of 18 hexagonal sections.
It is so big that it had to be folded to fit the rocket.
The maneuver was strictly isolated by laser-guided NASA to limit any contact with particles or even human-breathed telescope mirrors.
Once the rocket has carried the web for 120 kilometers, the spacecraft’s protective nose, called the “ferring”, is lowered to lighten the load.
To protect the fragile instrument from changes in pressure at that stage, Rocket-Builder ArianeSpace installed a custom decompression system.
“Extraordinary measures for an extraordinary customer,” an official of the European Space Agency said in Kauro on Thursday.
The crew on the ground will know if the first phase of the flight was successful about 27 minutes after launch.
Once he arrives at his station, the challenge will be to fully adjust the mirror and tennis-court-sized sun shield.
That terribly complicated process will take two weeks and if the web is to function properly it must be flawless.
Its orbit will be much farther than Hubble, which has been 600 kilometers above the Earth since 1990.
The orbital location of the web is called the Lagrange 2 point and was chosen in part because it would place the earth, sun, and moon on the same side of its solar shield.
Webb is expected to officially enter service in June.
