Mars 12: Destination Mars

The Mars orbiter and lander arrived on Dec. The lander operated on the surface of Mars for 20 seconds before failing.

The Mars flyby module and lander arrived on March 3, but the lander failed due to a fast impact. The Mars flyby module and lander arrived on March 3, but the lander missed the planet. The Mars orbiter operated from June to and the lander operated from July to The Mars orbiter operated from Aug. Combined, the Viking orbiters and landers returned more than 50, photos. The Mars orbiter and Phobos lander were lost in Aug.

The Spacecraft Graveyard ]. The Mars orbiter and Phobos lander were lost in March near Phobos. The orbiter, two landers and two penetrators were lost after the rocket failed. The Mars lander and rover landed on July 4, and communicated with ground teams last on Sept.

Destination Mars

Mars is visible in the night sky without the help of a telescope, so it has fascinated people for thousands of years. We have learned a lot about the conditions on Mars by using powerful telescopes , sending robotic orbiters to study the planet from space, and placing landers and robotic rovers on the Martian surface.

The next big step is a human mission to Mars. But Mars has many features that are similar to Earth, such as polar ice caps, seasons, clouds, and a rocky surface with canyons and mountains see Earth and Mars: Comparison of Planetary Neighbours Backgrounder. Billions of years ago, Mars may have been more like Earth, with warmer temperatures and abundant liquid water. This makes Mars the most likely planet in our solar system, other than Earth, to have supported the evolution of life.

Finding signs of past life is a big goal of missions to Mars.

Scientists believe that Martian life was probably microbes , like bacteria. It is exciting to wonder if Martian microbes could still be living in protected areas. Even if life is never found outside Earth, exploring other planets satisfies human curiosity about our place in space. Learning more about the Martian climate and geology, and how they have changed over time, are additional goals of Mars missions.

This data will help scientists figure out if Mars was habitable in the past, and if it can be habitable for humans in the future. The earliest missions sent spacecraft on a planetary "fly-by".

Then, orbiters were sent to study Mars from a stable orbit like a satellite , and eventually landers reached the Martian surface See Figure 1. The rovers, called Opportunity and Curiosity, are investigating Martian geology, looking for liquid water, and searching for signs of life in soil and rocks See Figure 2. There are also several inactive landers and rovers from past Mars missions still on the planet's surface.

In , NASA plans to launch its InSight lander mission to explore under the surface of Mars to learn how rocky planets, like Earth, are formed and changed over time. The Mars Rover is scheduled for launch two years later.

It will continue to search for life and gather data that will help future astronauts survive on Mars. Its main purpose is to look for signs of life on Mars, by studying atmospheric gases and exploring the surface. SpaceX's Dragon capsule, launched by the Falcon 9 rocket, has been delivering supplies to the International Space Station since More powerful versions of the capsule and the rocket, called Dragon 2 and Falcon Heavy, will be used for the Martian mission.

Mars is our closest planetary neighbour but it is still very far away. The distance between Earth and Mars is constantly changing due to their orbits around the Sun. It is, however, 16 light years away and thus well beyond our current reach given that 16 light years is more than a million times further from the Earth than the Sun is. For advocates of a Mars mission, the idea of a base on the Moon looks pedestrian by comparison. And as Buzz Aldrin, the second man to step on the Moon, said last year, the prize in going to Mars could well be the chance to tap into the rich mineral belt beyond it.

There is, however, no avoiding the fact that the best estimate of how long it will take to travel to Mars is around six months — compared to three days to the Moon. But all is not lost, as the reality may be similar to how long-distance space travel has been depicted in movies, with crews passing the time in deep sleep. NASA is currently funding a study into the feasibility of this, spurred on by the idea that a comatose crew would need fewer supplies and a lot less physical space, too.

It attempted to show the potential challenges and dangers that a manned mission to the red planet posed. Back at the Mars Desert Research Station, a good crew will typically be highly motivated and so taken with the escapade that getting them to stop working is a major challenge. Bad crews complain of boredom. The consensus is that missions should be led from the front, by the astronauts, and not back on Earth.



Man first landed on the moon in Its goal is to bring down the astronomical costs associated with space transportation — and also to put a man on Mars. For Musk, Mars is a top priority. Zubrin thinks Musk might just do it.
