In November 2015, Administrator Bolden of NASA reaffirmed the goal of sending humans to Mars. He laid out 2030 as the date of a crewed surface landing, and noted that planned 2020 Mars rover would support the human mission.

Radiation exposure is among the top health risks for Mars astronauts, but the Red Planet poses many other dangers as well. The most immediate threat to human health on Mars is the low pressure of the planet's atmosphere, which is about 100 times thinner than Earth's.

There's a growing chorus of calls to send astronauts to Mars rather than the moon, but critics point out that such trips would be long and gruelling, taking about six months to reach the Red Planet. But now, researchers are testing a powerful new ion engine that could one day shorten the journey to just 39 days.

The trip takes around seven months; a bit longer than astronauts currently stay on the International Space Station. The precise duration of each journey depends on when it is taken. Because both Mars and Earth's orbits are not perfectly circular, the time it takes to travel between them varies from six to eight months.

The numbers get a little wiggly, owing to the constant movement of the two involved planets, but a crewed trip to Mars, using current technology, would take about nine months. That's quite a road trip. The point is, there's a whole lot of space out there and getting anywhere interesting takes way too long.

See NASA's big plans for its new Mars rover, Perseverance (CNN) The NASA Perseverance rover has been confirmed to be healthy and is now on a journey to Mars. It will take between 6.5 and seven months before the rover lands on the red planet in February 2021.

The initial concept included an orbiter and small robotic lander in 2018, followed by a rover in 2020, and the base components in 2024. The first crew of four astronauts were to land on Mars in 2025. Then, every two years, a new crew of four would arrive.

While cats (particularly those of Ulthar) are said to be able to jump to the Moon, Mars is presumably a leap too far, thus there are no cats, living or dead on the red planet. Michael Georgiades, Amateur science enthusiast.

SATCAT no. Curiosity is a car-sized rover designed to explore the crater Gale on Mars as part of NASA's Mars Science Laboratory mission (MSL). ... The rover is still operational, and as of July 20, 2020, Curiosity has been on the planet Mars for 2827 sols (2904 total days) since landing on August 6th, 2012.

In fact: If you could walk from Earth to Mars at a brisk rate (about five miles per hour) it would take about 4,000 years to reach the Red Planet. If you drove a car 70 mph, it would take 228 years. If you had a 747 airlane, it would still take 32 years.

-Though Mars is just over 2x times larger in diameter than the Moon, it's also more than 143 times farther away, even at its said hypothetical closest.

Over the years, NASA has sent four robotic vehicles, called rovers, to Mars--and NASA plans to send another soon. In total, the four rovers that have already gone to Mars are: Sojourner, Spirit and Opportunity, and Curiosity. The Perseverance rover will be heading to the Red Planet soon. Mars is a fascinating planet.

The total journey time from Earth to Mars takes between 150-300 days depending on the speed of the launch, the alignment of Earth and Mars, and the length of the journey the spacecraft takes to reach its target.

The notional journeys outlined in the November 2016 talk would require 80 to 150 days of transit time, with an average trip time to Mars of approximately 115 days (for the nine synodic periods occurring between 2020 and 2037).

A Quora question: Has Elon Musk been in space? My guess is also no, Elon has not been into space physically; non-physically many times! Elon is an entrepreneur which makes him a risk taker, however, he most definitely weighs every decision carefully with the future involved.
