What will humans eat on Mars ? It’s a daunting question: the red planet’s frigid average temperature is around negative 80 degrees Fahrenheit and its thin atmosphere is comprised of 95.32 percent carbon dioxide . But not to worry, future astronauts. NASA’s on it, as are several other institutions worldwide. Inhabitat rounded up six exciting space farming projects revealing the progress scientists have made on the issue of sustainable space cuisine. Scientists grow potatoes in Mars-like conditions, justifying The Martian’s Mark Watney Scientists from the International Potato Center , NASA’s Ames Research Center , and Peru’s University of Technology and Engineering recently showed the 2015 movie The Martian may have not just been science fiction after all. Inside a CubeSat , a small satellite in which the scientists could simulate Mars conditions, they were able to sprout potatoes , the crop of choice for astronaut Mark Watney in the film. Their research shows maybe we could grow those tubers on Mars after all, but also could offer insight into how to cultivate crops here on Earth in climate change -impacted regions. Related: Six scientists just completed a year-long simulated Mars mission Scientists find four crops grown in Mars-like soil are edible Wageningen University scientists in the Netherlands have also been growing crops in Mars-like soil. They successfully cultivated ten crops – like tomatoes, rye, and peas – in dirt provided by NASA that came largely from a Hawaii volcano, but feared the resulting food might be filled with heavy metals . Further tests showed they didn’t have to worry quite so much: at least four of the crops do not contain heavy metals like cadmium, lead, or arsenic and are edible. The Wageningen team hopes to continue their research and raise more money for their project. Astronauts harvest lettuce on the International Space Station International Space Station (ISS) astronauts are in on the space farming effort too. In 2014, Orbital Technologies Corporation’s Veggie system was deployed to the ISS , and recently in late 2016, NASA checked in with space gardener astronaut Shane Kimbrough who has harvested multiple batches of lettuce on the space station. The experiment not only gives astronauts the chance to nibble on some rare fresh greens harvested every ten days or so, but will also further NASA’s knowledge of how different life forms perform in zero gravity environments. Self-contained greenhouse could grow plants with Earth air on Mars The Mars Plant Experiment (MPX) was a small, self-contained greenhouse with enough Earth air to last 15 days and around 200 seeds of the flowering plant Arabidopsis used often in research. The little greenhouse would have hitched a ride to Mars aboard a rover for the 2020 mission. One of 58 proposed experiments, MPX didn’t make the list of seven selected payload proposals NASA announced a little over two months after Inhabitat’s article, but it’s still an intriguing idea for how humans might go about growing plants on Mars. NASA Advanced Food Technology team designs over 100 vegan recipes for future Mars crew Forget freeze-dried ice cream. NASA’s Advanced Food Technology project took a healthier approach by looking into an entirely vegan diet for future space voyagers. They developed more than 100 vegan recipes for a six to eight person Mars crew, featuring fresh fruits and vegetables possibly grown in hydroponic systems. Veganism wasn’t so much a ideological choice for the NASA team as a practical one: it would be difficult to store easily perishable dairy and meat products during the lengthy trip to Mars. Experts suggest kitchen garden for astronauts venturing to Mars All the way back in 2011, NASA was pointing to kitchen-style gardens as a solution for astronauts, realizing pre-packaged food alone probably wouldn’t cut it for deep space missions. Speaking at an American Chemical Society gathering, scientist Maya Cooper of NASA’s Space Food System Laboratory said chefs and horticultural experts could help devise a plan for producing the over 7,000 pounds of food required for the five year journey to Mars. Experts identified 10 likely candidates for a spaceship kitchen garden: cabbage, spinach, herbs, carrots, strawberries, tomatoes, peppers, spring onions, radishes and lettuce – of course we’re now growing that last plant already on ISS. In just over five years, scientists have come a long way in developing space farming , and we’re excited to see what innovations crop up in the upcoming years as humanity prepares to go to Mars.

We test drove the new Chevrolet Bolt and heres the scoop

When we were invited to test-drive the brand new Chevy Bolt electric vehicle, we naturally jumped on the opportunity. The new Chevrolet Bolt is Chevy’s first mass-market all-electric vehicle, designed for those who want to go further than a hybrid plugin electric like the Chevy Volt . With a range of 238 miles per charge (better than the Nissan Leaf and comparable to the much higher priced Tesla Model S ), for a price tag of around the 30K (after the tax rebates), many have high hopes for the Chevy Bolt as the first true “electric vehicle for the masses”. We were curious to see how this car would fare in real life, and were excited to check it out. Hailed by automotive enthusiasts as the “Tesla Killer,” the Bolt has been a frontrunner in the competition against Tesla’s more affordable electric car, the Model 3 , and now enjoys an entire year’s head start to market. Will the Bolt bring a new wave of adoption for electric vehicles? Read on for our thoughts: We set out in our burnt orange Bolt EV just an hour south of San Francisco, along the picturesque, tree-lined roads of Portola Valley. From the minute we hit our first hill-hugging turn, we knew that we were in for a smooth experience. The car carries the bulk of its weight in its floor-mounted lithium-ion battery pack, which translates to a lower center of gravity, better structural integrity, and ultimately a more enjoyable ride than most gas cars. Naturally of course, the car is extremely quiet as well, without any vroom vroom of an engine. The unique placement of the battery also allows for a flatter floor, making the Bolt noticeably roomier then the Volt and many of its electric vehicle competitors. With AeroVironment’s Level 2 charging station the battery can be recharged to full in only eight hours, making charging as simple and intuitive as plugging in before going to bed. On straighter stretches we were able to zip from 0-60mph in an impressive 6.5 seconds. Drivers can choose between “Drive” and “Low” modes, and while Low mode permits speeds as highs as those in Drive mode, its “regenerative” braking system cleverly funnels braking friction back into the battery the moment the driver lifts their foot from the pedal. A paddle behind the left side of the steering wheel can be used to the same effect or to increase brake regeneration, so much so that the car can come to a complete stop without hitting the brakes. It’s ideal for stop-and-go traffic and even better for conserving energy. Drivers can visualize the energy captured on the car’s 10.2-inch touch screen display. With an impressive 238-mile range per charge, Bay Area owners can make a complete one-way trip to Tahoe without having to refuel, making the Bolt far more suitable for weekend trips than many of its EV competitors, such as the Nissan Leaf . The car’s official MSRP is $37,495 but a federal tax credit of $7500 puts it firmly in the under $30,000 range. All in all, it is easy to see why the Bolt EV might be a tempting choice for those in the market for an electric vehicle. With exceptional range, groundbreaking technology, and roomy interior, we’re convinced the Bolt delivers on everything it promised. Chevy Bolts officially went on sale at dealerships across the West Coast this past December and will be reaching excited customers across the nation by mid 2017. + Chevrolet Bolt
