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.
