TUCSON, Ariz. – University of Arizona Regents Professor of Astronomy Marcia Rieke, principal investigator for the James Webb Space Telescope's Near-Infrared Camera, or NIRCam, will join other Webb scientists and engineers to discuss the end of telescope commissioning and the beginning of instrument commissioning during a NASA teleconference.
In early February, the Webb team successfully captured starlight through each of Webb's 18 mirror segments. In the following months, as Webb's science instruments cooled to their operating temperatures, the team progressed through the seven stages of mirror alignment. With the successful completion of the final stage in late April, all four of Webb's science instruments can now capture sharp, focused images.
Among those instruments are NIRCam and the Mid-Infrared Instrument, or MIRI. UArizona Regents Professor of Astronomy George Rieke is MIRI's science team lead.
The Webb team will now take about two months to prepare and test the science instruments – a process known as instrument commissioning – before Webb's first science images are released to the public in the summer.
Teleconference participants will discuss the recent completion of mirror alignment and preview what to expect for Webb's final months of science instrument preparations.
In addition to Marcia Rieke, participants include:
- Michael McElwain, Webb observatory project scientist, NASA's Goddard Space Flight Center
- Jean Dupuis, space astronomy senior mission scientist, Canadian Space Agency
- Christopher Evans, Webb project scientist, European Space Agency
- Klaus Pontoppidan, Webb project scientist, Space Telescope Science Institute
Webb, an international partnership with NASA, the European Space Agency and the Canadian Space Agency, launched Dec. 25 from Europe's Spaceport in Kourou, French Guiana. After unfolding into its final form in space and successfully reaching its destination 1 million miles from Earth, the observatory is now in the months-long process of preparing for science operations.
Webb will explore every phase of cosmic history – from within the solar system to the most distant observable galaxies in the early universe, and everything in between. Webb will reveal new and unexpected discoveries and help humanity understand the origins of the universe and our place in it.
