2024年8月22日 · The spacecraft bus provides the necessary support functions for the operation of the Webb Observatory. The Spacecraft Bus is part of Webb's "Spacecraft Element" which is comprised of the Spacecraft Bus and the Sunshield.

While the payload itself typically garners the most attention, it's the spacecraft bus that carries and supports every aspect of the mission for the life of that craft. And in the case of the James Webb Space Telescope, the bus performs its vital role with a robust and trusted design that sets a new standard for engineering creativity.

The JWST spacecraft bus provides the telescope with electrical power, attitude control, thermal control, command and data handling, communications services, and propulsion. Its solar array provides the electrical power needed for the mission, with a capacity of up to 3 kilowatts.

The spacecraft bus is a carbon fibre box that houses systems of the telescope and so is the primary support element of the James Webb Space Telescope, launched on 25 December 2021.

JWST's propulsion system provides maneuvering capability for orbital insertion, station keeping, and spacecraft momentum management. The JWST propulsion subsystem is the part of the spacecraft bus that provides the means to correct JWST's orbit at the second Sun-Earth Lagrange point (L2), to control attitude in certain ACS modes, and to unload ...

JWST's communications subsystem is the part of the spacecraft bus that provides 2-way communications to and from the observatory during certain ground testing activities and throughout the operational phase. S-band frequencies are used for command uplink, low-rate telemetry downlink, and ranging.

2024年8月28日 · Learn about the design and the major components and subsystems of Webb and see Webb in a 3d in a 3d Solar System. The observatory is the space-based portion of the James Webb Space Telescope system. The Webb Space Telescope is the most powerful space telescope ever made – and the most complex one yet designed.

The James Webb Space Telescope (JWST), launched in December 2021, is a cutting-edge observatory designed to explore the universe in infrared wavelengths, offering unprecedented insights into the early universe, exoplanets, stellar evolution, and cosmic phenomena.

2021年12月25日 · In relation to the James Webb Space Telescope, the spacecraft bus is the large box positioned underneath the main telescope. When taking a more detailed look at the JWST, you will first find the different goals and purposes of the next-generation telescope.

2014年6月5日 · The spacecraft bus will provide the necessary support functions for the operation of the Webb Observatory after it is launched into space in 2018. The bus is the home for six …
