There have been around 50 Mars missions so far, of which about half have been successful — a testament to the difficulty in reaching the red planet.
Orbiting Mars are eight satellites, providing massive amounts of data on our dusty neighbor. More missions are planned for the and launch windows, and there are proposals to put humans on Mars by the s. It launched on April 7, , and holds the record as the longest-operating spacecraft orbiting Mars. It is projected to remain in operation until While Beagle 2 suffered a lander failure, the Mars Express satellite has remained in successful communication with Earth.
This data has been incredibly valuable and has earned the craft several end-date extensions. The Spirit and Opportunity rovers arguably represent one of the biggest success stories of the current NASA space program. Launched separately in summer , the pair of rovers arrived on the red planet after about six months.
Initially, the plan was for a day mission to study the geology and atmosphere of Mars. The MRO has been observing the landscape and has made numerous high-profile discoveries, including the recent observance of flowing saltwater on the surface and subsurface of the planet.
MRO was also used to find a landing zone for the Phoenix Lander, and acts as a relay for communications between active rovers and Earth. The rover is equipped with a vast array of instruments and cameras and has been operational on Mars since Mangalyaan is also outfitted with a small suite of research instruments designed to capture atmospheric data.
Researchers hope to gain a better understanding of methane and other trace gases present in the martian atmosphere that could be evidence for possible biological activity.
It is hoped the data collected will lead to a better understanding of how rocky planets such as Earth, Mars, Venus, and Mercury are formed. Chinese watch in wonder as country begins building own space station and gears up to land a rover on Mars. Military powers around the world are taking conflict technology to the next frontier — outer space.
Published On 24 Jun China must also develop technology to fly astronauts back to Earth. From: NewsFeed. The next logical step for Mars exploration is permanent settlement, where crews that go to Mars stay and build a new society. Humans settling on Mars will inspire us all to make Earth a better place. Technology, scientific understanding, cooperation — is there anything we cannot achieve?
Mars One was founded in with the goal of sending humans to Mars to stay. Instead of trying to return them, more crews would be sent every two years, establishing a permanent, ever-growing settlement on the Red Planet.
Permanent settlement missions place even higher demands on the crew than a return mission. A first permanent settlement crew would be on Mars for two years before the second crew joins them.
They would be able to communicate with friends and family on Earth, but only with time delays. Crew selection, training and testing on Earth would be necessary to make sure they can deal with this. Besides that, they would need to learn all the skills to survive on Mars without support from Earth, other than information. They would need to be able to fix every technical and medical problem, grow food and expand the settlement with hardware for upcoming crews.
