The Radio Science Subsystem (RSS) Small Forces Record (SFF) files are generated by the MESSENGER project when there is a propulsive event. They give estimated information on the cumulative delta-V effect on the spacecraft due to thruster firing, mass loss due to the expenditure of propellant, and cumulative on-times for each individual thruster.

RSS SFF products have the following file names:

MESS_RS_yyyyddd_yyyyddd_SFF.TXT (with detached PDS label)

where:

MESS = mission = MESSENGER

RS = instrument = Radio Science Subsystem

yyyyddd = start date, year and day

yyyyddd = stop date, year and day

SFF = product type = Small Forces file

In ODE, SFF products have the following product IDs:
