The company is one of NASA's largest contractors and is one of several currently working on projects related to Mars. So far, only unmanned rovers and orbiters have made it to the Red Planet. When ...
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.
We choose to go to the Moon. We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we ...

Mars mission design. The 90-Day Study estimated SEI's long-term cost at approximately 500 billion dollars spread over 20 to 30 years. According to Steve Dick, NASA Chief Historian, the National Academy of Sciences largely concurred with the NASA study, but White House and Congressional reaction to the NASA plan was hostile, primarily due to the cost estimate.

And we're about to witness Mars reaching opposition in 2025. Even though we can’t hop into a rocket and fly into the galaxy, luckily there are moments when the planets seem to reach out to us ...
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.
A collection of Martian rocks could reveal details about potential past life on the Red Planet – but first NASA has to get them back to Earth.. For years, the U.S. space agency's Perseverance ...
