Modus Operandi of tomorrow's TCM

MOM will first roll over to achieve the right orientation necessary
for carrying out the Trajectory Correction Manoeuver (TCM). MOM
will then command the 22 N thrusters on board to fire for about 44
seconds and attain the necessary incremental velocity.

After the firing, MOM will roll back to an optimal orientation which
ensures coniinuous communication with Earth, uninterrupted
power generation and proper solar heating.

Since MOM is about 2.9 million km away from Earth, the amount of
time required for the signal to go and come back is about 20
seconds. Hence the entire operation is managed by the on board
computer.

The first crucial TCM is scheduled for 06:30 hrs IST on 11.12.13 and
we will be able to bring you the "real-Time" update with a transit
delay of 10 seconds.
