NASA plans to launch the James Webb Space Telescope into orbit Dec. 18,
2021, to serve as the premier deep space observatory for the next decade.
The agency set the new target launch date in coordination with Arianespace
after Webb recently and successfully completed its rigorous testing regimen
– a major turning point for the mission. The new date also follows
Arianespace successfully launching an Ariane 5 rocket in late July and
scheduling a launch that will precede Webb. The July launch was the first
for an Ariane 5 since August 2020.
Webb, an international program led by NASA with its partners ESA (European
Space Agency) and the Canadian Space Agency, will launch on an Ariane 5 from
Europe's Spaceport in French Guiana on the northeastern coast of South
America. ESA is providing the Ariane 5.
The highly complex space telescope is currently resting in its final stow
configuration at Northrop Grumman’s facilities in Redondo Beach, California.
“Webb is an exemplary mission that signifies the epitome of perseverance,”
said Gregory L. Robinson, Webb’s program director at NASA Headquarters in
Washington. “I am inspired by our dedicated team and our global partnerships
that have made this incredible endeavor possible. Together, we’ve overcome
technical obstacles along the way as well as challenges during the
coronavirus pandemic. I also am grateful for the steadfast support of
Congress. Now that we have an observatory and a rocket ready for launch, I
am looking forward to the big day and the amazing science to come.”
The Webb team is preparing for shipment operations, during which the
observatory will undergo final closeout procedures and packing for its
journey to the launch site. The major elements of the Ariane 5 rocket that
will carry Webb into space have safely arrived in Kourou, French Guiana,
from Europe.
The Webb telescope’s revolutionary technology will explore every phase of
cosmic history – from within our solar system to the most distant observable
galaxies in the early universe, and everything in between. Webb will reveal
new and unexpected discoveries, and help humankind understand the origins of
the universe and our place in it.
