NASA, Webb Telescope Completed Posting – Last Hour

(ANSA) – Washington, Jan. 09 – Two weeks after launch, the James Webb Space Telescope has completed its deployment phase, fully opening the primary mirror, the largest mirror ever sent into space, at six and a half meters in diameter. A team of technicians celebrated after the minute activation stages of the Large Telescope with a NASA announcement in the halls of the Telescope Science Institute in Baltimore, Maryland. The US space agency noted the extreme complexity and sensitivity of the deployment of all components of the Webb telescope, folded to be able to enter the narrow space of the nose of the Ariane 5 rocket that carried it into space from French Guiana on Christmas Day. . A few days ago, Webb completed the opening of his solar shield, a kite-shaped, 21-meter-long, which will protect the telescope from light, heat and solar radiation.

Meanwhile, the complex is heading towards the chosen orbital point 1.5 million kilometers from Earth, the so-called Lagrange Point 2 (L2), where it will be in gravitational equilibrium and which it will reach in a few weeks. And from where he will begin to explore deep space, reaching optical distances that have not been reached before, and getting as close as possible – according to the theory of astronomers – to the original universe 13 and a half billion years ago, near the Big Bang.

“I was impressed, what an amazing landmark,” said Thomas Zurbuchen, a senior engineer at NASA.
