They would need to be able to fix every technical and medical problem, grow food and expand the settlement with hardware for upcoming crews. Crew selection is the biggest challenge of a permanent settlement mission to Mars. Mars One had a business plan for such a mission to Mars, which can be summarized as monetizing the media value of the adventure of humans going to Mars.
The Moon landing is still the TV program with the highest viewership density ever. Imagine the value of a mission to Mars in the current media era. Mars One raised funds by having investors invest in a Mars One media company that held the rights to the mission. With their feedback, Mars One developed a plan that was feasible, affordable and that had an acceptable risk. In , the plan was announced, later followed by a job vacancy for Mars settlers.
Winds energized by the Sun's heating of the ground can form large and well-formed whirlwinds known as vortices.
They mostly are invisible, but when a strong vortex drifts over a dusty surface, dust is lifted into it and reveals its shape. This animation was shot over four minutes on Sol and captured a "dust devil" vortex at a distance of one-half to one km from the rover. The dust devil is about 5m wide and at least 50m tall. Curiosity took its latest "selfie" on Sol to celebrate the successful drilling of three holes on the rock slab in front of it.
The first two holes were named after Mary Anning, the 19th Century palaeontologist whose findings in the seaside cliffs of southwest England contributed to the understanding of prehistoric marine life on Earth.
Material from these holes was used for two "wet chemistry" experiments, in which it was mixed with liquid chemicals to extract organic molecules that may be preserved in the rock. Rocks at this site formed from sediment carried in ancient streams and lakes.
The wet environment and the presence of organic molecules in several rocks studied by Curiosity suggest that ancient Mars was habitable, capable of supporting life, if it ever took hold. The third hole was drilled to study dark nodules visible in the corner of the slab. A Martian day, or Sol, lasts 24 hours and 39 minutes. The 3,th Sol of the Curiosity mission is marked on 12 January. The robot landed on the planet on 6 August This video can not be played To play this video you need to enable JavaScript in your browser.
Another brief glitch in briefly stopped science work, but the rover quickly resumed its mission. In the months after landing, NASA noticed damage to the rover's wheels appearing much faster than expected.
By , controllers made in the rover's routing to slow down the appearance of dings and holes. It's just the magnitude of what we're seeing that was the surprise. NASA pioneered a new drilling technique at Mount Sharp in February to begin operations at a lower setting, a requirement for working with the soft rock in some of the region.
Previously, a rock sample shattered after being probed with the drill. Engineers had mechanical trouble with Curiosity's drill starting in ate , when a motor linked with two stabilizing posts on the drill bit ceased working.
NASA examined several alternative drilling techniques, and on May 20, the drill obtained its first samples in more than 18 months. It should be noted that Curiosity isn't working alone on the Red Planet. Accompanying it is a "team" of other spacecraft from several countries, often working collaboratively to achieve science goals. As of mid, Curiosity is working on the surface along with another NASA rover called Opportunity , which has been roaming the surface since Opportunity was initially designed for a day mission, but remains active after more than 14 years on Mars.
It also found past evidence of water while exploring the plains and two large craters. NASA's Mars Odyssey acts as a communications relay for Curiosity and Opportunity, while also performing science of its own — such as searching for water ice. More surface missions are on the way shortly. Mars will carry different instruments, however, to better probe for ancient life. It will also cache promising samples for a possible Mars sample return mission in the coming decades.
In the more distant future, NASA has talked about sending a human mission to Mars — perhaps in the s. In late , however, the Trump administration tasked the agency with sending humans back to the moon first.
His administration also requested that funds for the International Space Station cease in , in part to make budgetary room for a moon space station initiative called the Deep Space Gateway. Join our Space Forums to keep talking space on the latest missions, night sky and more!

The very first thing Perseverance will do after landing is to fire some pyrotechnic devices, releasing the covers on cameras on board the rover. After that? Over the next few days, Perseverance will go through a number of important tasks to ensure it is up and running smoothly.
The next five days, meanwhile, will be spent transitioning from the software the rover used to land to the software it needs to operate on the surface. While all this is going on, however, another team will be poring through images of the landing site, getting ready for a major test—the first flight on Mars. Tucked into the belly of Perseverance is a small 0.
Once it finds that site, the deployment will be slow. Ingenuity is stored sideways under Perseverance, so it must be slowly rotated and lowered to the surface. The legs must be unfolded with the help of springs, while the helicopter must receive a final jolt of charge from Perseverance before it switches to its own onboard solar-powered battery. Then, once all checks have been complete and everything is ready, it will be gently dropped to the surface. In theory, this whole process—apart from the battery charge—takes just minutes.
