Peroxides or irradiated perchlorates seem to mimic life rather well on the Martian surface. Would it be correct to call this colonisation in a sociological context, if the colonized have no claim to sentience? Life is consistent with all these signatures – though it’s hardly the simplest explanation. Mars could be, as you say, a future example of human flourishing. SpaceX’s Falcon Heavy had its maiden flight in February 2017, igniting a firestorm of media coverage, and a flurry of tweets from the company’s CEO, Elon Musk. The first long-term habitats will have to be underground, or buried in ice and regolith. The Falcon 9 and its derivative, the Falcon Heavy, are at last complete, and the design team is now moving on to bigger and better things. Curiosity used a dust-removal tool for the first time to clean this patch of rock on the Martian surface on January 6, 2013. A human presence on Mars seems an ever closer prospect. Sub-image one of three shows the rover and its tracks after a few short drives. The question is, what kind? We have sent out countless missions to explore, send back photos and bring back samples, yet an official observation of life has yet to be made. Stranded astronaut Watney travels to the rim of Mawrth Crater. Not colonizing Mars when the ability to do so exists, because of microbes, is a far greater ethical failure. Over a decade ago, the Mars Express orbiter detected methane, a biomarker, and the Curiosity rover recently showed that levels vary seasonally. This find is similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers. And with this potential event, do we run into ethical issues. Largely undisturbed for gigayears, Mars provides a window onto the Solar System’s past. Minor correction: Falcon Heavy’s first flight was 2018, not 2017. If there is independent life on Mars, then Mars is its inheritance – not ours. SpaceX is merely the most visible and successful representative of a larger movement. HiRISE stands for High Resolution Imaging Science Experiment, a camera on NASA's Mars Reconnaissance Orbiter. What is the moral value of native Martian life vs. creating a "backup Earth"? NASA's Curiosity rover found evidence for what scientists believe was an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here. The Mars rover Curiosity recorded this view from its left navigation camera after an 83-foot eastward drive on November 18, 2012. On the right are rocks from "Yellowknife Bay," where rover Curiosity was situated. We don’t have enough data to decide with any certainty, but suppose life did exist on Mars. It shows the rover's shadow on the Martian soil. We also cover issues such as palm oil, soya, low carbon diets and labels. Sparrow, Robert, The Ethics of Terraforming. That's an incredibly morally valuable thing. Test flights have been optimistically scheduled for late 2019, and demonstration flights to Mars are scheduled for 2022. Failing to analyze any possible Martian life would be a great loss to the store of potential human knowledge. The company’s meteoric rise has been accompanied by failures, delays, setbacks and (naturally) explosions, but Space X has made the half-century-long dream of rapid and cheap reusable orbital spacecraft into a reality – and its competition isn’t far behind. It would be hubris for us to assume that humanity on Earth would last forever. Do we have a moral obligation to microbes? Food & Drink guides, news and features Two blast marks from the descent stage's rockets can be seen in the center of this image. More than 39,000 images have been taken by HiRISE since the Mars Reconnaissance Orbiter reached Mars in 2006. Everything in history -- all art, progress, science, technology -- is for nothing. Life may have evolved eons ago on Mars, and just been driven underground. The massive rocket thundered off its launchpad, while the accompanying corporate webcast blasted David Bowie. After a full-scoop sample had been vibrated over the sieve, this portion was returned to the scoop for inspection by the rover's mast camera. The image was obtained by the Mars Descent Imager instrument known as MARDI and shows the 15-foot diameter heat shield when it was about 50 feet from the spacecraft. A self-portrait taken by NASA's Curiosity rover on June 15, 2018. The outer band of the parachute has a reddish color. In Defence of Argument: “Intellectual Freedom and the Culture Wars” by Piers Benn. The rounded shape leads the science team to conclude they were transported by a vigorous flow of water. Life on Mars will be tough. Think of that the next time you overcome a common cold, or take antibiotics to cure a more serious infection or actually eat… anything. This color full-resolution image showing the heat shield of NASA's Curiosity rover was obtained during descent to the surface of Mars on August 13, 2012. "The Martian" used actual locations on Mars for the landing sites for its Ares 3 and Ares 4 missions. If we weren’t careful, Martian settlers would end up “living on a collapsing landscape,” as the global permafrost-like soil melted. The rock on the left, called "Wopmay," was discovered by the rover Opportunity, which arrived in 2004 on a different part of Mars. This is the calibration target for the imager.
