Snapped January 28, the image shows exposed layered bedrock, which the team determined was probably sediments laid down by water. While Spirit struggled, Opportunity clearly was an early overachiever.

It was really a very different experience. Eagle crater was just the first crater Opportunity explored. For instance, in a risky move just months after its Mars arrival, the rover drove inside the edge of stadium-sized Endurance crater.
Only later did the team realize that promontory had huge fractures in it. It was really like a new landing site. This was the first investigation of the rim of such a big impact crater anywhere in the solar system, Fraeman says. Do they deliver organics and heat to the surface? Or are they bad for life, do they sterilize the surface? One thing scientists do know is that the Endeavour crater was once yet another watery environment, with chemistry that would have been favorable to life if anything had lived there. Water interacted with the rock multiple times.
One of the best pieces of evidence for water at Endeavour crater is this vein of gypsum, spotted in November Gypsum is made of calcium, sulfur and water, and probably formed from water dissolving calcium out of volcanic rocks. Its chemistry suggests that the water in this region was less acidic than other wet environments Opportunity had uncovered, so might have been better for life.
But it was really a new thing when we saw it at Endeavour. Not every rock Opportunity spotted formed where the rover found it. Using spectrometers on Opportunity, the team determined that the basketball-sized space rock was made mostly of iron and nickel. Opportunity subsequently found three or four additional obvious meteorites and several smaller candidates as it roamed. The rover will then drive away to a safe distance.
The Mars rover will act as a telecommunication relay, receiving commands from engineers back on Earth and relaying them to the helicopter. The helicopter will then send images and information about its own performance to the rover, which will send them back to Earth. The rover will also take measurements of wind and atmospheric data to help flight controllers on Earth.
Radio signals take time to travel to Mars — between four and 21 minutes, depending on where Earth and Mars are in their orbits — so instantaneous communication with the helicopter will be impossible. Instead, they need to send commands to the helicopter in advance, and the little flying robot will follow through.
A future Mars helicopter could scout points of interest, help scientists and engineers select new locations and plan driving routes for a rover. Larger standalone helicopters could carry science payloads to investigate multiple sites at Mars. Future helicopters could also be used to fly to places on Mars that rovers cannot reach, such as cliffs or walls of craters.
They could even assist with human exploration one day. Says Balaram: "Someday, if we send astronauts, these could be the eyes of the astronauts across Mars. Mars has a thin atmosphere. Computer-generated animation of the Mars Helicopter in flight. Alternative funding approaches might include the creation of inducement prizes.
For example, the President's Commission on Implementation of United States Space Exploration Policy suggested that an inducement prize contest should be established, perhaps by government, for the achievement of space colonization. One example provided was offering a prize to the first organization to place humans on the Moon and sustain them for a fixed period before they return to Earth. Mars Odyssey found what appear to be natural caves near the volcano Arsia Mons. It has been speculated that settlers could benefit from the shelter that these or similar structures could provide from radiation and micrometeoroids.
Geothermal energy is also suspected in the equatorial regions. Several possible Martian lava tube skylights have been located on the flanks of Arsia Mons. Earth based examples indicate that some should have lengthy passages offering complete protection from radiation and be relatively easy to seal using on-site materials, especially in small subsections. Hellas Planitia is the lowest lying plain below the Martian geodetic datum. The air pressure is relatively higher in this place when compared to the rest of Mars. Some analysts have calculated that one needs to drill into the Martian crust for around Robotic spacecraft to Mars are required to be sterilized, to have at most , spores on the exterior of the craft—and more thoroughly sterilized if they contact "special regions" containing water,   otherwise there is a risk of contaminating not only the life-detection experiments but possibly the planet itself.
It is impossible to sterilize human missions to this level, as humans are host to typically a hundred trillion microorganisms of thousands of species of the human microbiome , and these cannot be removed while preserving the life of the human. Containment seems the only option, but it is a major challenge in the event of a hard landing i. One possible ethical challenge that space travelers might face is that of pregnancy during the trip.
According to NASA's policies, it is forbidden for members of the crew to engage in sex in space. NASA wants its crewmembers to treat each other like coworkers would in a professional environment. A pregnant member on a spacecraft is dangerous to all those aboard. The pregnant woman and child would most likely need additional nutrition from the rations aboard, as well as special treatment and care.

At some point during the trip, the pregnancy would most likely impede on the pregnant crew member's duties and abilities. It is still not fully known how the environment in a spacecraft would affect the development of a child aboard.

It is known however that an unborn child in space would be more susceptible to solar radiation, which would likely have a negative effect on its cells and genetics. It is unforeseen how the first human landing on Mars will change the current policies regarding the exploration of space and occupancy of celestial bodies. Since the planet Mars offers a challenging environment and dangerous obstacles for humans to overcome, the laws and culture on the planet will most likely be very different from those on Earth.
Mars colonization is advocated by several non-governmental groups for a range of reasons and with varied proposals. Mars to Stay advocates recycling emergency return vehicles into permanent settlements as soon as initial explorers determine permanent habitation is possible. Elon Musk founded SpaceX with the long-term goal of developing the technologies that will enable a self-sustaining human colony on Mars. I think it is absolutely realistic. It will happen I think over the next 20 years, we will take literally hundreds of thousands of people to space and that will give us the financial resources to do even bigger things".
In June , Buzz Aldrin , American engineer and former astronaut , and the second person to walk on the Moon , wrote an opinion, published in The New York Times , supporting a human mission to Mars and viewing the Moon "not as a destination but more a point of departure, one that places humankind on a trajectory to homestead Mars and become a two-planet species".
