Engineers use a special crane to install the instrument deck onto NASA’s Magnetospheric MultiScale (MMS) Structure #2 in the early hours of December 11, 2012.

Installation of instrument deck is complete on MMS Observatory #2, the second of four observatories being assembled in the special MMS cleanroom at NASA’s Goddard Space Flight Center in Greenbelt, Md.

MMS Observatory #2 will remain at Goddard during the next several months while engineers and technicians integrate additional flight hardware and conduct necessary functional and environmental tests.
