Caltech’s Jet Propulsion Laboratory (JPL) will manage GRAIL’s
mission operations from its Pasadena facility and provide navigation and
mission support using heritage operations systems (Multi-mission Ground System
Services and the Deep Space Network). GRAIL’s indstrial partner, Lockheed
Martin Space Systems (LM), will conduct spacecraft flight operations from
the Denver facility that also supports Mars Odyssey, the Mars Reconnaissance
Orbiter, and the Phoenix mission.
JPL and LM have a longstanding and successful partnership of over 15 years
that has been proven over many planetary missions. Both are well-versed in
the use of existing ground system infrastructure for ssemble Test and Launch
Operations (ATLO) and flight operations.
Science Level 0 and 1 data processing will be done at JPL with 90% reuse
of software from the GRACE mission; Level-2 processing will be done at JPL,
the Goddard Space Flight Center (GSFC) and the Massachusetts Institute of
Technology (MIT); advanced products and scientific interpretation will be
performed by the science team institutions. The final delivery of science
data products to Planetary Data System is performed by MIT.
Project Management
The GRAIL team is staffed
with experienced management and scientific personnel with specific experience
in Earth and planetary gravity mapping investigations. The Project Scientist,
Mission System Manager, and Instrument Manager on GRAIL had the same roles
on GRACE.
