The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy.As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. [9]
It will feature a 2-meter (6.6 foot) diameter primary mirror and is expected to have a field of view 300–350 times larger than the Hubble Space Telescope. [7] This will allow the telescope to image up to 40 percent of the sky using its 2.5 gigapixel camera. Xuntian Space Telescope mockup, showing its docking port
Scale comparison between the primary mirrors of the Hubble Space Telescope, James Webb Space Telescope, and the proposed LUVOIR-B and LUVOIR-A. Selected large telescopes which are in detailed design or pre-construction phases: Large UV Optical Infrared Surveyor (LUVOIR), a proposed space telescope for launch in the mid 2030s.
The Hubble tension is one of the most hotly debated discrepancies in all of astronomy. It centers around a number called the Hubble constant, which is functionally the rate at which our universe ...
The Corrective Optics Space Telescope Axial Replacement (COSTAR) is an optical correction instrument designed and built by NASA. It was created to correct the spherical aberration of the Hubble Space Telescope ' s primary mirror , which incorrectly focused light upon the Faint Object Camera (FOC), Faint Object Spectrograph (FOS), and Goddard ...
Musgrave assisted Hoffman into the restraint and Hoffman proceeded to replace two sets of Rate Sensing Units (RSUs). These units contain gyroscopes that help keep Hubble pointed in the right direction. By 17:24 UTC, Hoffman had finished replacing RSU-2 (containing Gyros 2–3 and 2–4) and then replaced RSU-3 (containing Gyros 3–5 and 3–6).
The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14 ...
STS-125, or HST-SM4 (Hubble Space Telescope Servicing Mission 4), was the fifth and final Space Shuttle mission to the Hubble Space Telescope (HST). The launch of the Space Shuttle Atlantis occurred on May 11, 2009, at 2:01 pm EDT. [2] [3] [4] Landing occurred on May 24 at 11:39 am EDT, [5] with the mission lasting a total of just under 13 days.
