Comparison with Missions by NASA and SpaceX

Aspect	MOM (ISRO)	NASA’s MAVEN	SpaceX’s Mars Missions
Budget	$74 million	$671 million	Estimated over $1 billion
Launch Year	2013	2013	Ongoing
Primary Objective	Atmosphere and surface exploration	Study upper atmosphere	Human colonization (future)
Duration	7+ years	Still operational	Varies (depending on mission)
Technology	PSLV	Atlas V	Falcon Heavy, Starship

While NASA’s MAVEN focused specifically on Mars’ upper atmosphere, MOM had a broader set of objectives within its budget constraints. SpaceX, on the other hand, is working towards ambitious plans for human colonization of Mars, aiming to transport large payloads with its Starship system.
