The MIRI Science Team met at STScI and discussed ongoing efforts at STScI and the overall MIRI Guaranteed Science Program. STScI MIRI team members gave presentations on coronagraphic observation planning & operations, the JWST 3D Exposure Time Calculator, and a study of how science parallel observations might be implemented.

The Integrated Science Instrument Module (ISIM) Cryo-Vac Test 2 began and STScI MIRI team members are supporting this multi-month testing campaign along with MIRI team members from Europe and the USA.

May 2014
The MIRI team at STScI supported the continued characterization at the Jet Propulsion Lab (JPL) of the state-of-the-art Si:As detectors. MIRI team members staffed shifts during the testing and have started analyzing a subset of the data taken.

January 2014
Over the last year, the MIRI instrument was successfully integrated into the Integrated Science Instrument Model (ISIM) and checked out at cryogenic temperatures during the Cryo Vac 1 Risk Reduction (CV1RR) testing. The MIRI CV1RR testing results show that the instrument is performing as expected as the CV1RR data are fully consistent with the previous instrument level testing results taken at Rutherford Appleton Laboratory in the United Kingdom.

The MIRI flight model was flown from London Heathrow airport to Washington Dulles International Airport on May 29, 2012. It was subsequently trucked to Goddard Space Flight Center and unpacked on May 30th. It now rests in the clean-room awaiting integration into the ISIM. View MIRI and monitor the progress of ISIM integration.
