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

Being in direct contact with India is probably a boon to operations; remaining in orbit to do checkouts/adjustments prior to the Mars trip has more benefits than just a smaller rocket, in terms of signal delay, familiar environment, etc.
Why doesn't this happened more often? Launch a probe into parking orbit when it's assembled, do checkouts and instrument commissioning at a leisurely pace, and burn with your final stage to interplanetary when the appropriate window opens up. |

Why doesn't this happened more often? Launch a probe into parking orbit when it's assembled, do checkouts and instrument commissioning at a leisurely pace, and burn with your final stage to interplanetary when the appropriate window opens up. I don't know the answer, but two thoughts come immediately to mind. One, checkouts and instrument commissioning don't seem to take all that long -- a few days, at most a week. Two, Earth orbit may not be a good place for deep-space probes to spend lots of time; there are the radiation belts, at perigee they're encountering Earth's exosphere, and so forth. Earth satellites can survive for decades, but they're designed for it. It's possible that a week in Earth orbit might strip several weeks of the potential lifespan of a Mars orbiter. Doug M. |
