Is it possible that humans once lived on Mars?
Well, strictly speaking, you can’t. Mars is a completely hostile environment to human life, combining extreme cold with an unbreathable atmosphere and intense radiation. And while it is understood that the planet once had an atmosphere and lots of water, that was billions of years ago!
Is there any chance humans will be on Mars?
Robotic spacecraft have given us great views. No humans have ever tried to go to Mars. No human missions to Mars will be tried for years. In fact, the first people on Mars may be your age today. When you are grown, maybe you will watch--or even be one of--the people who make the first trip to Mars! NASA is working hard to find if there is life ...
Why is landing on Mars so difficult?
The reason it is so hard to land on Mars is that the atmospheric pressure is low, less than 1% of Earth’s surface pressure. This means that any probe will descend very rapidly to the surface, and...
Will humans ever land on Mars?
Per the agency's website, NASA's stated goal has been to land humans on Mars "in the 2030s," and that remains the case today. NASA's so-called " Journey to Mars " will follow several steps, including lots of biological research on board the International Space Station and a possible manned asteroid landing around 2025.

The average flight to Mars takes about nine months, so depending on the timing of launch and available fuel, it is plausible that a human mission could reach the planet and return to Earth in less than two years, according to Yuri Shprits, a UCLA research geophysicist and co-author of the paper.
Is there life in Mars?
To date, no proof of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid water and may have been habitable for microorganisms, but habitable conditions do not necessarily indicate life.

Will NASA ever launch to Mars?
The first crewed* mission to Mars will probably be either privately financed or by NASA, sometime in the next 20 years. The sooner the launch is attempted, the more likely it is that everyone on board will die en route or on arrival, so NASA is being pretty cautious about their schedule, having already lost three crews between the Apollo and Shuttle missions, and Russia has had nothing but catastrophic failures of the biggest rockets it tried to build, so I don’t think they are planning to take over the Red Planet; they’d rather make the Earth Red, if they had the economic and military strength to do it. But they’re just barely a first-rate, if not second-rate power, as the battle for supremacy in space and on Earth is going to be between the US and China. China has not stated whether they have any interest in Mars (at least, that I’ve heard of); they seem more interested in Taiwan, the South China Sea, everything from the Pacific to the Atlantic, and the Moon.
What are some examples of Mars missions?
An example of this is the imaging campaigns by Mars Express of the Mars moons.

When did NASA send astronauts to Mars?
In 1966, NASA fought hard to send astronauts careening past Mars in 1976. The Joint Action Group (JAG) plan would have sent a four-person crew to Mars and back without landing, equipping them with a 40-inch telescope to scout the surface as they zoomed by. But new, up-close images of Mars proved to be a buzzkill.
What was the Mars Project?
In an effort to liven up his days, von Braun researched and wrote The Mars Project, a novel about a manned Mars expedition. “The main idea, I think, was to escape from where he was,” says David Portree, an archivist at the U.S. Geological Survey's Astrogeology Science Center and author of Humans to Mars. The novel’s detailed technical appendix described a physically plausible series of spacecraft, routes, and even launch dates.

When will Elon Musk bring humans to Mars?

For von Braun, the Apollo Program was only supposed to be the beginning; he personally planned out a subsequent Mars ...
Did Von Braun fly Venus?
Von Braun wasn't the only one ; another NASA proposal considered conducting a manned flyby of the planet Venus in the mid-1970s. At that rate, humans could have visited more distant planets like Jupiter by the end of the century. But science often doesn't go as planned.
Is Mars landing more distant than SpaceX?
NASA's scheduled Mars landing is more distant and vague than that of SpaceX. Even so, it's quite possible that both organizations are being overly optimistic; the aftermath of the Space Race proves that the future of space exploration is hard to predict and estimates are constantly being pushed back.
Overview
A Mars landing is a landing of a spacecraft on the surface of Mars. Of multiple attempted Mars landings by robotic, uncrewed spacecraft, ten have had successful soft landings. There have also been studies for a possible human mission to Mars, including a landing, but none have been attempted. Soviet Union’s Mars 3, which landed in 1971, was the first successful Mars landing. As of May 2021, the Soviet Union, United States, and China have conducted Mars landings successful…
Methods of descent and landing
As of 2021, all methods of landing on Mars have used an aeroshell and parachute sequence for Mars atmospheric entry and descent, but after the parachute is detached, there are three options. A stationary lander can drop from the parachute back shell and ride retrorockets all the way down, but a rover cannot be burdened with rockets that serve no purpose after touchdown.
Descent of heavier payloads
For landers that are even heavier than the Curiosity rover (which required a 4.5 meter (15 feet) diameter aeroshell), engineers are developing a combination rigid-inflatable Low-Density Supersonic Decelerator that could be 8 meters (28 feet) in diameter. It would have to be accompanied by a proportionately larger parachute.
Landing challenges
Landing robotic spacecraft, and possibly some day humans, on Mars is a technological challenge. For a favorable landing, the lander module has to address these issues:
• Thinness of Mars's atmosphere
• Measurement of distance to surface
• Inadequate technology for ballistic aerocapture
Communicating with Earth
Beginning with the Viking program, all landers on the surface of Mars have used orbiting spacecraft as communications satellites for relaying their data to Earth. The landers use UHF transmitters to send their data to the orbiters, which then relay the data to Earth using either X band or Ka band frequencies. These higher frequencies, along with more powerful transmitters and larger antennas, permit the orbiters to send the data much faster than the landers could manag…
