As the red planet continued its slow march around the sun, a burst of solar material buffeted the atmosphere. No big deal—such changes in solar weather are pretty common. Its observations back up scientists' suspicions that solar activity is a major player in shaping Mars's atmosphere, a finding that is even more exciting when viewed with an extremely patient eye. Given this new understanding of how the sun affects Mars, it seems likely that a stormy adolescent sun could be the reason Mars went from warm and wet to the chilly, barren world we see today.
Since the PSLV was not powerful enough to place MOM on a direct-to-Mars trajectory, the spacecraft was launched into a highly elliptical Earth orbit and used its own thrusters over multiple perigee burns to take advantage of the Oberth effect to place itself on a trans-Mars trajectory.
Radhakrishnan announced that the launch had to be postponed by a week as a result of a delay of a crucial telemetry ship reaching Fiji. The launch was rescheduled for 5 November Its main engine, which is a derivative of the system used on India's communications satellites, uses the bipropellant combination monomethylhydrazine and dinitrogen tetroxide to achieve the thrust necessary for escape velocity from Earth.
It was also used to slow down the probe for Mars orbit insertion and, subsequently, for orbit corrections. The first three of the five planned orbit raising manoeuvres were completed with nominal results, while the fourth was only partially successful.
However, a subsequent supplementary manoeuvre raised the orbit to the intended altitude aimed for in the original fourth manoeuvre. A total of six burns were completed while the spacecraft remained in Earth orbit, with a seventh burn conducted on 30 November to insert MOM into a heliocentric orbit for its transit to Mars.
The first orbit-raising manoeuvre was performed on 6 November at During the fourth orbit burn, the primary and redundant coils of the solenoid flow control valve of newton liquid engine and logic for thrust augmentation by the attitude control thrusters were being tested.
When both primary and redundant coils were energised together during the planned modes, the flow to the liquid engine stopped.
Operating both the coils simultaneously is not possible for future operations, however they could be operated independently of each other, in sequence. Trans-Mars injection On 30 November at The second trajectory correction manoeuvre was performed on 11 June at At the Advanced Propulsion Research Workshop, The concept of ion propulsion, currently being demonstrated on the Deep Space 1 mission, goes back to the very beginning of NASA and beyond.
