according to the Chinese Xinhua press agency an Indian Mars probe may be launched in 2013 or 2015, after Chandrayaan-2

this is interesting http://www.firstpost.com/tech/indias-mars-...013-459232.html
QUOTE “As in the case of Chandrayaan-1, we will have to take the spacecraft first into the earth’s orbit from 22,000 km to 200,000 km in stages using the propulsion system and fire the rocket’s liquid apogee motor to push it into the Martian orbit after cruising about 300 days” this looks like the mission profile of the Soviet Fobos missions, of Mars 96 and Fobos-Grunt |

When your propulsion system is not very powerful or very accurate, it is preferable to split large burns into segments (when possible). This prevents large "gravity losses" (for long burns) and gives the mission time to measure and correct any under/over burns. In a nutshell: it saves fuel, when there is not much to spare. Tolis. |
