We know the launch date of the James Webb Space Telescope!

That’s it ! At last ! The Nasa, l’THIS and Arianespace have set a date for the highly anticipated launch of the JWST alias the telescope space James Webb, often presented as the replacement for Hubble (31 years in space).

After nearly two decades of very expensive development, a series of delays and postponements for its departure for space, here we are: the JWST will be able to take off on December 18, as planned, folded inside the capsule who will be at the top of a launcher Ariane 5. We can’t wait to see this and that the telescope deploys its magnificent golden mirror to look at the dark side of theuniverse. See you on Saturday, December 18 to discover the event live, from Guyana. Until then, don’t miss our series on the extraordinary James Webb Space Telescope.

The launch of the JWST, the James Webb Space Telescope, is still postponed!

On Thursday, NASA announced the second postponement of the launch of James Webb, a large space telescope valued at $ 10 billion. Finally, it will be launched by the rocket Ariane 5 on October 31, 2021 instead of March, due to the pandemic and other development issues. ” Webb is the world’s most complex space observatory and our top scientific priority, we’ve been working hard to keep moving forward during the pandemic Said Thomas Zurbuchen, the scientific director of NASA.

Imagined in the 1990s, this telescope was initially to be launched in the 2000s. But countless development issues, at the main manufacturer Norhtrop Grumman, led to multiple postponements and a doubling of the cost … Estimated at 4.5 billion in 2007 by NASA, it climbed to 9.66 billion dollars in 2018.

The telescope, launched from Kourou (Guyana), will be placed in orbit around soleil. 1.5 million kilometers from Earth. Once his sun shield is unfolded, it will be as tall as ” a tennis court “. It will have a mirror main three more sensitive than that of Hubble, launched in 1990, and which will measure 6.5 meters in diameter. A huge size in order to ” detect the faint glimmer of the distance stars et galaxies ».

The launch of the James Webb space telescope probably still postponed

Four years after the first decoding of the 24 chromosomes who make up the genome human, refinement is continuing in laboratories around the world in order to fill in the gaps. It is in the journal Nature that the complete sequence of chromosome 5 was published, which marks the path of half of the path of the in-depth approach undertaken, ie twelve more chromosomes to be analyzed in detail.

the James Webb Space Telescope Launch seems to no longer want to end being delayed. A document published by the Government Acountability Office (GAO) estimates the chances that the telescope will be launched by Ariane 5 to March 2021 as it had been announced during the summer of 2018. Because a good part of the time of the calendar reserve taken was consumed by problems at the level of two components necessary to transmit scientific data to Earth .

The report specifies that the project managers did not, however, “Currently not intend to change the launch readiness date in response to this analysis alone”, but they plan “To reassess its feasibility in spring 2020, after the completion of important technical steps”.

And better to make sure all the tech is in good working order before launch. Because unlike télescope spatial Hubble whose low orbit has authorized operations of maintenance, the James Webb Space Telescope will orbit some 1.5 million kilometers from Earth. Which will prohibit any human intervention.
