Mars Orbiter Mission now halfway to moon

RATE THIS! +51
Posted in Science on 18th Nov, 2013 12:38 AM by AlexMuller

The Indian Space Research Organisation (Isro) on Saturday completed the fifth orbit-raising move of its Mars Orbiter Mission (MOM) spacecraft. The spacecraft has covered half the distance to the moon.

 
The mission was launched through spacecraft PSLVC25 on November 5.
 
Isro officials said the fifth-orbit raising manoeuvre started at 1:27 am, with a burn time of 243 seconds and an incremental velocity of 101.55 m/s. In the process, the 440N liquid engine raised the apogee from 118,642 km to 192,000 km.
 
The next step would be trans-Mars injection, in the early hours of December 1, after which the spacecraft would travel 1,000,000 km a day for 300 days. The December 1 operation would impart a specific velocity to the spacecraft so in September the spacecraft reaches close to Mars (500 km, +/-50).
 
“The crux of the success of the operation on December 1 is we should be able to estimate precisely the velocity, and the time we need to impart the velocity to the spacecraft so it takes that position. In that, the computation of the spacecraft navigation is important: How it passes from the sphere of influence of the Earth and enters a heliocentric orbit,” said Chairman K Radhakrishnan.
 
On September 24, Isro would have to reduce the velocity. “If we are able to reduce the velocity precisely at that point, we will get the orbit and, finally, the instruments will be operated.”

Mars is definitely a target that should be explored in many ways. This Oribter by Isro adds to the effort from other nations

Mars was so far explored just enough to be very intriguing. Many speculation about life forms and water have been debated- it is time to find out more Reply

It is important to understand Mars better-what the history of the atmosphere has been, how the climate has changed through time and how that has influenced the evolution of the surface and the potential habitability – at least by microbes

For centuries people have speculated about the possibility of life on Mars due to the planet's proximity and similarity to Earth. It is time now to find out more Reply

In September this year Mars is going to have many visitors: when Maven reaches Mars it will join three functioning spacecraft, two US and one European. India's Mangalyaan also will be arriving about the same time. Reply

It is also important to find out about minerals across Mars. In particular about aluminum-rich clay minerals and those that containe iron and magnesium clays. Reply
