If you want to send a spacecraft all the way to Mars, first you’ll need a fast rocket to escape the pull of Earth’s gravity. The heavier your spacecraft, the more powerful your rocket needs to be to lift off. Next, make sure you launch at the right time. Mars and Earth orbit the sun at different speeds and distances.
Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles. … That is, humans should be able to safely travel to and from Mars, provided that the spacecraft has sufficient shielding and the round trip is shorter than approximately four years.
Antimatter propulsion
An engine fueled by antimatter could attain 19,000 miles a second. Trips to Mars in days or even hours are possible – if you can survive the warp-speed acceleration. Pros: Very, very fast. With this under the hood, you just have time for a nod to the Red Planet as you head out to Alpha Centauri.
NASA is recruiting to send humans to Mars as soon as 2037.
Turns out, deadly space radiation puts a hard limit on living on Mars. A new paper written by an international group of space scientists details the threat of particle radiation on future human colonists of Mars.
Temperatures on Mars average about -81 degrees F. However, temperature’s range from around -220 degrees F. in the wintertime at the poles, to +70 degrees F.

The basics. Unfortunately, setting up camp on the Moon is much more difficult than sending astronauts there fora few days. Unlike the Apollo astronauts, lunar settlers wouldn’t be able to carry all their rations and resources on their rocket. It would be too heavy.
Wernher von Braun proposal (1947 through 1950s) Wernher von Braun was the first person to make a detailed technical study of a Mars mission. Details were published in his book Das Marsprojekt (1952, published in English as The Mars Project in 1962) and several subsequent works.
Flying through outer space has dramatic effects on the body, and people in space experience aging at a faster rate than people on Earth. … These studies showed that space alters gene function, function of the cell’s powerhouse (mitochondria), and the chemical balance in cells.
A: Jupiter is a gas giant, which means it probably does not have a solid surface, and the gas it is made up of would be toxic for us. It is also very far from the sun (sunlight can take over an hour to get there) which means that is it very cold.
Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.
( Maybe someday we could manufacture rocket fuel on Mars ). In fact, you can only land a small part of the ship on Mars, because landing everything on the surface and lifting it off again would require enormous amounts of fuel. … That means you will have to spend 3-4 months at Mars before you can begin your return trip.

But the Martian atmosphere is much thinner than Earth’s, meaning atmospheric pressure is so low that the blood of any unprotected visitor would boil.

Like Earth, Mars is tilted away from the Sun on its axis, so as it travels around the Sun there are times during the Martian year (days) that a part of the planet does not receive direct sunlight. This axial tilt causes four seasons on Mars, which is similar to Earth.

The pay grades for civilian astronauts are GS-11 through GS-14, based on academic achievements and experience. Currently, a GS-11 astronaut starts at $64,724 per year; a GS-14 astronaut can earn up to $141,715 in annual salary [source: NASA].
That’s called a solar prominence. … But if you take a look around, there’s nothing here for you to actually land on, because the sun doesn’t have any solid surface to speak of. It’s just a giant ball of hydrogen and helium gas. So instead of landing on the photosphere, you’re going to sink into it.
But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
