The Webb Space Telescope is now on its way to its parking orbit as a fully assembled space telescope
It appears that the perfect launch of the Ariane 5 rocket on Christmas Day may be crucial in giving Webb a longer life than expected. Once it’s at L2 it will be in a near-perfect alignment with the Sun, the Earth and the Moon. The only fuel it will need will be for the occasional correction to keep it in that orbit. That fuel is limited because everything is limited when you launch such a heavy payload into space.
. It’s seemingly a result of “the efficiency or the accuracy with which Ariane put us on orbit and our accuracy and effectiveness in implementing our mid-course corrections.”“On January 23 we’ll arrive at our LG insertion location but while we get there we’ll begin phasing the mirror—taking its 18 mirror segments and aligning them so they behave as one monolith,” said John Durning, Webb Deputy Project Manager at NASA Goddard.
