Webb’s Coldest Instrument Reaches Operating Temperature

PARIS (ESA PR) — With help from a cryocooler, Webb’s Mid-Infrared Instrument has dropped down to just a few degrees above the lowest temperature matter can reach and is ready for calibration.

The James Webb Space Telescope will see the first galaxies to form after the Big Bang, but to do that its instruments first need to get cold – really cold. On 7 April, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by ESA and NASA – reached its final operating temperature below 7 kelvins (minus 266 degrees Celsius).

  • On December 25, 2021 at 9:20 a.m. local time (1:20 p.m. CET), the James Webb Space Telescope, the largest space telescope of all time to date, took off from the spaceport of the European Space Agency on an Ariane 5 launcher.
  • A total of four instruments are housed on James Webb.  Two of them come from Europe and have German shares.
  • The German Space Agency at DLR coordinates the German contributions for ESA and for an instrument in the national space program.

KOUROU, French Guiana (DLR PR) — James Webb Space Telescope – JWST for short – was launched from the European spaceport in Kourou (French Guiana) on its journey to Lagrange Point 2, 1.5 million kilometers away.  James Webb is the largest and most expensive space telescope of all time, which has now started its long journey into the depths of space with an Ariane 5 upper stage ‘Made in Germany’. In addition, MIRI (Mid Infrared Iinstrument) and Near Infrared ( Near Infrared Spectrograph) – two of the four instruments on board – German parts: The near-infrared instrument NIRSpec was built by Airbus in Ottobrunn and Friedrichshafen. With this instrument, scientists from all over the world want to analyze the ‘hours of birth’ of the universe. NIRSpec is primarily intended to detect the radiation from the first galaxies that formed shortly after the Big Bang.

SWINDON, UK (UK Space Agency PR) — The once-in-a-generation James Webb Space Telescope has launched, with scientists and engineers across the UK playing a vital role in the mission.

The telescope, known as ‘Webb’, blasted off from the Arianespace spaceport in French Guiana on 25 December 2021 at 12:20 pm – the culmination of decades of scientific collaboration.

Before the MIRI instrument – one of four scientific instruments aboard the observatory – can operate, it has to be cooled down to almost the coldest temperature matter can reach.

PASADENA, Calif. (NASA PR) — Set to launch on Dec. 22, NASA’s James Webb Space Telescope is the largest space observatory in history, and it has an equally gargantuan task: to collect infrared light from the distant corners of the cosmos, enabling scientists to probe the structures and origins of our universe and our place in it.
