What is the current status of the big observatory? This is how you can find out.

NASA's
proposed $10 billion observatory is nearing the end of a tense series of stages
that will determine its ultimate configuration and placement.
The
"29 days on the edge," as NASA has nicknamed the lengthy and
intricate deployment process for the James Webb Space Telescope, began when the
spacecraft launched on Saturday (Dec. 25). The observatory has made significant
progress since then, including unfurling its solar array and modifying its
trajectory. Steps like opening the sunshield and adjusting the mirrors are
still to come.
The
observatory's progress can be followed on the NASA website dedicated to themission. The spacecraft's location and speed are detailed on the webpage.
Webb has
already travelled more than one-third of the distance to its ultimate orbit,
circling a location known as L2, or the Earth-sun Lagrange point 2, after only
a few days on the road. The gravitational tugs of the sun and Earth are
balanced here, approximately 1 million miles (1.5 million kilometres) away from
Earth on the opposite side of the solar, creating a comparatively stable
environment for spacecraft.
The
dashboard will display temperatures for both the hot side of the spacecraft,
which faces the sun, and the cold side, which will be shielded by the enormous
sunshield, after Webb's temperature sensors are deployed.
The main
dashboard also includes information from NASA's primary deployment timeline
concerning the most recent deployment stage Webb has completed.
The
telescope will be fully deployed 13 days after launch, around Jan. 7, and will
reach its ultimate orbit 29.5 days after launch if everything goes according to
plan. Following that, the observatory will be commissioned for five months in
order to prepare its equipment and mirror for science activity, which is
planned to begin in the summer of 2022.
