Webb has completed internal checks. All ground stations and the spacecraft are go for launch. Spacecraft and launch engineers at the Jupiter Control Center at Europe's Spaceport in French Guiana and at the Mission Operations Center at the Space Telescope Science Institute in Baltimore, Maryland, have confirmed that Webb is on internal battery and is …
Fueling for both the main and upper stages of the Ariane 5 rocket is now complete. In preparation for launch scheduled for no earlier than 7:20 am EST (9:20 am GFT). The cryogenic arms attached to the Ariane 5 are now supplying top-up fuel until liftoff. All systems are being continually measured to monitor the readiness …
Webb has been confirmed as being go for launch, and the countdown clock was started! With weather reports looking favorable, the team authorized fueling of the Ariane 5, which began at 3 am EST. Arianespace will measure winds at high altitude with the help of balloons to ensure absolute safety for the launch. Meanwhile the …
Both immediately after launch and over the following weeks, the James Webb Space telescope will pass through numerous milestones on its journey of approximately 1 million miles to its final orbit around the second Lagrange point, commonly known as L2. NASA has a detailed plan to deploy the Webb Space Telescope over a roughly two-week …
The latest weather forecast has arrived and we are still go for launch tomorrow! The target launch date for the James Webb Space Telescope is Dec. 25. A 32-minute launch window opens at 7:20 a.m. EST in Kourou, French Guiana (9:20 a.m. GFT/12:20 UTC).
