It takes a lot of fuel to blast off Mars and get back home. If the propellant has to be transported there from Earth, costs of a launching soar. Without some radical improvements in technology, the prospects for sending astronauts on a round-trip to Mars any time soon are slim, whatever the presidential rhetoric.
This system is also much more precise: while the Mars Exploration Rovers could have landed anywhere within their respective 93-mile by 12-mile (150 by 20 kilometer) landing ellipses, Mars Science Laboratory landed within a 12-mile (20-kilometer) ellipse. [7] Mars 2020 has even more precise system, and landing ellipse of 7.7 by 6.6 km. [8]
Opportunity, also known as MER-B (Mars Exploration Rover – B) or MER-1, and nicknamed Oppy, is a robotic rover that was active on Mars from 2004 until 2018. [1] Opportunity was operational on Mars for 5111 sols (14 years, 138 days on Earth).
The vast majority of the Mars family fortune is derived from the eponymous company, one of the few conglomerates to have snubbed a stock market listing in favor of secrecy.
Opportunity landed in Meridiani Planum at , about 25 kilometers (16 mi) downrange (east) of its intended target on January 25, 2004, at 05: Although Meridiani is a flat plain, without the rock fields seen at previous Mars landing sites, Opportunity rolled into an impact crater 22 meters in diameter, with the rim of the crater approximately 10 meters (33 ft) from the rover.

CAPE CANAVERAL, Fla. (AP) — NASA is pitching a cheaper and quicker way of getting rocks and soil back from Mars, after seeing its original plan swell to $11 billion. Administrator Bill Nelson presented a revised scenario Tuesday, less than two weeks before stepping down as NASA’s chief when President-elect Donald Trump is inaugurated.
The lowest energy transfer to Mars is a Hohmann transfer orbit, a conjunction class mission which would involve a roughly 9-month travel time from Earth to Mars, about 500 days (16 mo) [citation needed] at Mars to wait for the transfer window to Earth, and a travel time of about 9 months to return to Earth. [9] [10] This would be a 34-month trip.
NASA says its history-making Mars helicopter Ingenuity has flown for the last time: The space agency says its rotor blades were damaged as the craft was landing, and it won't fly again.
