Following Webb's arrival at its orbital destination around Lagrange Point 2 (L2) on Jan. 24, the mission operations team began working its way through a critical series of steps: powering on all the science instruments, turning off heaters to begin a long cooldown process, and ultimately capturing the first photons on Webb's primary camera to …
The big news for Webb this week was the final insertion into orbit around the second Lagrange point. The team also turned on the High-Gain Antenna, enabling downlink to Earth through the Deep Space Network using the Ka radio band. The Ka-band provides a much higher data rate than the S-band that Webb has been …
Today, at 2 p.m. EST, Webb fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final postlaunch course correction to Webb's trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1 million miles away from the Earth. The final mid-course …
On Monday, Jan. 24, engineers plan to instruct NASA's James Webb Space Telescope to complete a final correction burn that will place it into its desired orbit, nearly 1 million miles away from the Earth at what is called the second Sun-Earth Lagrange point, or "L2" for short. Mathematically, Lagrange points are solutions to what …
Editor's Note: This post was updated to clarify the strength vs. stiffness of beryllium. Last week, the Webb team began moving the observatory's individual mirror segments out of their launch positions. Today, we hear from Erin Wolf, Webb program manager at Ball Aerospace, about the completion of that process: "Today, the James Webb Space Telescope …
With major deployments complete, Webb continues its journey to its final halo orbit around L2. In the meantime, there are several smaller deployments in the next couple of weeks, which constitute the beginning of a several-month phase of aligning the telescope's optics. This week, we have started the process of moving the mirror segments (all …
Webb has begun the detailed process of fine-tuning its individual optics into one huge, precise telescope. Engineers first commanded actuators – 126 devices that will move and shape the primary mirror segments, and six devices that will position the secondary mirror – to verify that all are working as expected after launch. The team also …
After two weeks of complex structural deployments, Webb has passed a major milestone and is now fully unfolded in space. For insight on what to expect in the months ahead and how to follow along, we hear from Alexandra Lockwood, project scientist for Webb science communications at the Space Telescope Science Institute: "Words can't describe …
Today, at 1:17 p.m. EST, NASA's James Webb Space Telescope completed all of its large-scale deployments with the extension and latching of its starboard primary mirror wing. Now that the telescope is structurally fully deployed – with the secondary mirror tripod and both primary mirror wings in place – the three-month process of aligning all …
The Webb mission operations team has given the ‘go-ahead' to move forward with the extension of its starboard primary mirror panel. This is the last of the major deployments on the observatory, and its completion will set the stage for the remaining five and a half months of commissioning, which consist of settling into stable …
