Engineering teams completed additional testing confirming NASA's James Webb Space Telescope is ready for flight. We share the live broadcast link with you. James Webb's Wednesday, December 22nd at 07:20 EST / 12:20 UTC / 13:20 CET'Launch preparations continue towards the target launch date in Additional testing was conducted this week to ensure the observatory's health following an incident that occurred when the release of a clamp band caused a vibration in the observatory. Previously, the launch date was set for December 18. We can say that the James Webb Telescope is Now Ready.
On Wednesday, November 24, engineering teams completed these tests, and a NASA-led anomaly review board concluded that no observatory components were damaged in the incident.
A “fuel approval” review was conducted, and NASA gave approval to begin refueling the observatory. Fuel operations started on Thursday, November 25 and will last approximately 10 days.
European launch service provider Arianespace, in partnership with NASA (American space agency) and ESA (European space agency), has defined December 22, 2021 as the targeted launch date for Flight VA256. Now we can say that the end is near.
“We are extremely honored to orbit NASA's James Webb Space Telescope with Ariane, a 'first' for Arianespace and the European space crew,” said Stéphane Israël, CEO of Arianespace.
“For 14 years, our teams have worked hard for Webb's debut, scheduled for December 18, 2021. The delay is only 4 days for now.
"As Ariane 5 accomplishes this mission, it's exciting to know that we will soon learn the deepest secrets of our Universe, especially how the first galaxies, stars and planets were born and evolved since then." There is also an explanation.
We will see key milestones ahead that will require the highest level of skill, dedication and excellence, such as the satellite pairing with the launcher. All of our teams in Continental Europe and French Guiana are focused on the Webb mission and are in daily contact with our partners ESA and NASA and our teams”.
The James Webb Space Telescope will be the largest, most powerful space telescope ever launched. Following Hubble, Webb was designed to answer deep questions about the Universe and make groundbreaking discoveries in all fields of astronomy.
Aiming to Investigate the Origins of Humanity
Webb will look deeper into our origins: from the formation of stars and planets to the birth of the first galaxies in the early Universe.
Webb is an international partnership led by NASA, with contributions from ESA and CSA. One of ESA's contributions to the collaboration is the launch of the observatory from the Ariane 5 launch vehicle.
Working with partners, ESA is also responsible for the development and qualification of Ariane 5 modifications for mission, such as the launch service acquisition and flight programs for NIRSPEC, as well as superstructure elements, particularly the cowling. These are the two main instruments of the Webb telescope, MIRI's optical system.
In the launch operation, the ESA program Ariane 5 will use the heavy load launcher. Ariane 5 is marketed and operated by Arianespace from the Guyana Space Center in Kourou, with participation from the French space agency CNES, responsible for the design and maintenance of the launch range and satellite preparation facilities.
Arianespace uses space to make life on Earth better by providing launch services for all types of satellites in all orbits. It has orbited more than 1980 satellites since 900 using three families of launchers, Ariane, Soyuz and Vega, from launch sites in French Guiana (South America) and the Russian cosmodromes in Baikonur and Vostochny.
Arianespace is headquartered in Evry, near Paris. It has a technical facility at the Guyana Space Center in French Guiana, as well as local offices in Washington, DC, Tokyo and Singapore. Arianespace is a subsidiary of ArianeGroup, which holds 74% of the equity capital.
