 "The Independent Review Board (IRB) established by NASA to assess progress
on its James Webb Space Telescope
<https://www.nasa.gov/mission_pages/webb/main/index.html> has unanimously
recommended that development on the world’s premier science observatory
should continue; NASA has established a new launch date for Webb of March
30, 2021."

"Webb will be folded, origami-style, for launch inside Arianespace’s Ariane
5 launch vehicle fairing – about 16 feet (5 meters) wide. After its launch,
the observatory will complete an intricate and technically-challenging
series of deployments – one of the most critical parts of Webb’s journey to
its final orbit, about one million miles from Earth. When completely
unfurled, Webb’s primary mirror

 will span more than 21 feet (6.5 meters) and its sunshield will be about
the size of a tennis court."
