yes
The latest information about India is that they have a mission to the mars.
Man will inevitably visit Mars someday, and in all likelihood, colonize it. But there are no plans for any kind of Mars mission at the moment that are anything beyond the "talk" stage.
The only space mitions on Mars that i know of would be the 2 Mars Rovers still currently exploring Mars.~2010
The Phoenix Lander was the most recent mission to Mars. It landed May 25, 2008 and the mission was over by November 10, 2008.
A rescue mission sure can be sent, but such a rescue mission can be horribly expensive. However, it depends where the stranded spacecraft is; if it is a mission on its way to Mars, for example, any such rescue mission is likely to arrive too late.

No they mostly looked at Mars.
The United States has two or three orbiting spacecraft in Mars orbits.
Spirit and Opportunity are two.
Mars has been in space for as long as any other planet, such as, earth.
yes there are many of them on mars and in the future i think they will visit our planet ('Earth')
