Scientists are bringing life on Mars closer and closer to reality by growing edible plants in soil similar to that of the red planet.
Researchers at Wageningen University in the Netherlands successfully grew 10 crops of which four so far have been tested and claimed edible, according to a Mars One statement. Radishes, peas, rye and tomatoes grown in Mars-like soil were deemed safe for human consumption.
"These remarkable results are very promising," senior ecologist Wieger Wamelink said. “We can actually eat the radishes, peas, rye, and tomatoes and I am very curious what they will taste like."
Scientists at Wageningen University have experimented with growing crops on Mars- and Moon-like soil simulants, developed by the National Aeronautics and Space Administration, since 2013.
The first round of experiments proved that plants could in fact be grown in the soil. Scientists then needed to test if the plants produced in the soil simulants would be edible.
Mars' soil contains heavy metals—aluminum, copper, iron, manganese, zinc, arsenic, cadmium, chrome, nickel and lead—that could be poisonous if consumed at certain levels.
"Mars One is very proud to support this important research," Bas Lansdorp, CEO and co-founder of Mars One, said. "Growing food locally is especially important to our mission of permanent settlement, as we have to ensure sustainable food production on Mars."
Wamelink and team's research is being funded by a crowdfunding campaign, which run until the end of August. So far, the project has raised 12,745 euros out of a goal of 25,000. The remaining money will fund the testing of the other six crops, including potatoes.
"It's important to test as many crops as possible, to make sure that settlers on Mars have access to a broad variety of different food sources," Wamelink said.

Who knew that the Windy City has become so green? As Co.Exist reported, Chicago is quietly becoming the country's urban agriculture capital with 821 growing sites across the city, from small community gardens to multimillion dollar indoor farms, according to the Chicago Urban Agriculture Mapping Project. Even O'Hare's Terminal 3 is home to the world's first airport aeroponic garden.
Chicago’s "urban farming renaissance" has been led by a burgeoning indoor farm market, Co.Exist writes. This includes FarmedHere, a 90,000-square-foot space in Bedford Park that is not only the first organically-certified indoor vertical aquaponic farm in Illinois, it’s also the largest indoor farm in North America. FarmedHere’s two-story farming facility currently sits on the site of a formerly abandoned warehouse in the outskirts of Chicago.
FarmedHere’s produce is grown in a sustainable environment where 97 percent of fresh water is reused and plants are grown without the use of herbicides or pesticides. The farm’s LED lighting system mimics outdoor conditions, meaning plants don’t need natural sunlight to grow.
EcoWatch previously mentioned how urban farming has really made a comeback in the U.S. in recent years. Cities around the world are developing and expanding their local food systems to create a more sustainable method of food production and distribution, which will become increasingly necessary as cities adapt to climate change.
Farmed Here CEO Nate Laurell also mentioned to Co.Exist that investors are becoming increasingly interested in indoor farming as LED lighting and solar energy drive operation costs "cheaper and cheaper." Incidentally, Chicago has relatively cheap electricity, with Chicago area households paying 15.4 cents per kilowatt hour versus the New York metro area average of 18.2 cents per kilowatt hour.
Projections show that the global vertical farming market is expected reach $3.88 billion by 2020, a figure that Laurell says is lower than what it actually might be.
"The greens market for Chicagoland alone is $400 million dollars," Laurell said. "Given the market is so big, and it’s so top of mind for people where their food came from and how it was grown, even if only some fraction of that food grew in an indoor environment, when you extrapolate to other cities in the U.S. and abroad, you’d easily reach $4 billion; $4 billion seems light."
Laurell explained that vertical farming is ideal compared to outdoor agriculture as it produces local food year-round, has a small geographic footprint, a high yield per cubic foot ratio and slashes food miles.
"On the consumer side, there is a large demand for local food, food grown close to the city. People want to know where their food comes from and cut out transportation miles to get more freshness," he added.
Farmed Here plans to expand to up to 15 cities within the next decade, Laurell said.
Urban Till is another indoor hydroponic farm. Located on the west side of Chicago, the company offers herbs and microgreens to more than 200 clients in the area, the Chicago Tribune reported last year.
CEO Brock Leach told the publication that Urban Till will expand nationally and internationally with its proprietary hydroponics this year.
“We have an intellectual property to produce more water from the air than what we use in the farm at no additional cost of electricity, and we’re able to produce agricultural goods without water supply to do so,” Leach said.
Chicago’s Pullman Park district also hosts the largest rooftop greenhouse in the world, a behemoth 75,000 square foot green space, built and opened by Gotham Greens in 2015.
"Our Pullman facility annually grows up to 10 million heads of leafy greens and herbs, year-round, for the finest retailers and restaurants across the greater Chicagoland area," the venture boasts.
The climate controlled greenhouse facility also sits on top of an already environmentally friendly factory occupied by eco-soap company Method.
Gotham Greens has three existing greenhouses in New York. "Chicago was a logical expansion because it is a large city—by market the third largest—a cold weather place with a short growing season and a limited supply of year-round local produce," Viraj Puri, CEO and cofounder of Gotham Greens, told Co.Exist.
"The traditional farmer in Illinois turns a head of lettuce twice a year, every 60 days—maybe a third turn if they’re lucky. We do 25 crop turns per year, and a lot of that has to do with controlling climate, temperature, humidity, light and carbon dioxide," Puri added.

The Solar Impulse 2 landed in Seville on Thursday, completing its historic trip across the Atlantic Ocean.
Solar Impulse 2, a sun-powered aircraft, took off from John F. Kennedy International Airport in New York City at 2:30 a.m. on June 20. The flight to Seville, Spain, took approximately 90 hours to complete—traveling at 140 km/h (about 87 mph). Bertrand Piccard, a Swiss adventurer, piloted the airplane.
“The Atlantic is the symbolic part of the flight," Piccard told The Guardian. “It is symbolic because all the means of transportation have always tried to cross the Atlantic, the first steamboats, the first aeroplane, the first balloons, the first airships and, today, it is the first solar-powered aeroplane."
Here are 10 best photos from Piccard's journey on the Solar Impulse 2:

Here at the Ready for 100 campaign, we believe in using bold messages to highlight bold opportunities. We know that achieving 100 percent clean energy will completely transform our communities, our economy and our environment and we are in awe of the growing movement of people who are bringing about that change.
We have a vision where every community is powered by clean energy sources, where no child has to stay home because of an asthma attack from dirty air and where people can find good jobs in industries that help protect our planet, not pollute it.
What's more, we believe that social change can be fun and that creativity and ingenuity can help us move the world as it is toward the world as we dream it can be.
So this summer, we're launching the #ReadyFor100 national tour, a “human art" event where thousands of people come together in cities across the country to create bold images showcasing the demand for clean energy.
In our launch event last night in Aspen, Colorado—one of the first cities in the country to commit to 100 percent clean energy—hundreds of people gathered in historic Snowmass Village to form an aerial image of a “human sun," designed by renowned aerial-artist John Quigley.
Over the next few months, you'll see similar art events happening in cities both large and small, from the East Coast to the West Coast, showing the public demand for 100 percent clean energy.
Sixteen municipalities across the country, including major cities like San Diego and San Francisco, have already committed to 100 percent clean energy and a movement is growing to urge other mayors to follow suit.
Aerial art events are a way to showcase how people, joining together, can build something dazzling, where the whole is greater than the sum of its parts. We hope that the people who join us at these events will bring their friends, families and anyone who wants to be inspired by a vision for a better future.
To join an “aerial art" event in a city near you, visit www.readyfor100.org to find out more details about our national tour.

Human-induced climate change promises to make life a lot harder for one of Australia's most charismatic species—the koala.
The herbivorous marsupial (Phascolarctos cinereus), unique to the world's largest island, is rarely seen. It moves slowly, lives high in the canopy on a diet of eucalyptus leaves, sleeps for up to 20 hours a day and yet is known to billions worldwide as the model for a cuddly toy loved by children.
Its demands are few: a supply of fresh eucalyptus foliage, a little water to drink and somewhere quiet to flourish. But a new study in Global Change Biology suggests that by 2070 much of its native homeland won't provide what it takes to make a home any more.
Potential Range
Natalie Briscoe, an ecologist at the University of Melbourne and colleagues used everything they knew about koalas—behavior, body size, fur depth and physiology—to predict how much energy and water koalas would need to survive at any location. They made the assumption that eucalyptus trees would be available everywhere.
Then they used their knowledge of the animal to make a map of potential koala habitat 60 years from now. And they found the animal's potential range dramatically smaller.
The problem lies not in inexorable global warming—average planetary atmospheric temperatures have risen by 1 C in the last century and the world has pledged to keep the overall rise to lower than 2 C— but in the frequency of extremes of heat and drought. And in a land of extremes, more extremes are on the way.
Dr. Briscoe said:
“Studies of climate change impacts on wildlife have often focused on how changes in average temperature or rainfall will affect species, but our research highlights the importance of thinking about the extreme conditions that will be most stressful for the animals—such as hot, dry periods—and how these may change in the future.
“By developing a better understanding of what controls species distributions now, we are much better placed to forecast how these may shift in the future."
The researchers also correlated all the known koala locations and then matched that data with climate records from the recent past—another way of helping understand what climate change can do to wildlife. Both models predicted that the animal would suffer in the hotter, drier parts of its range.
Rainfall Patterns
The summer of 2013 broke all records for temperature extremes in Australia and researchers expect rainfall patterns to be disrupted and heatwaves and droughts to grow in number and intensity with time.
The challenge for conservationists is to identify those regions where the koala is more likely to survive. Ecologists call these places refugia: in times of stress, a species retreats to a limited range and expands when conditions improve.
“There is a lot of uncertainty when predicting the impacts of climate change on species, particularly when climate change leads to novel weather patterns," Dr. Briscoe said.
“Comparing predictions from different models allows us to more confidently predict the location of havens where koalas could survive in the future."

Mark Z. Jacobson’s new digs is the perfect home for the prominent renewable energy advocate.
The Stanford professor's Solutions Project famously lays out roadmaps for 139 countries, including the world’s major greenhouse gas emitters, to switch to 100 percent clean, renewable energy generated from wind, water and sunlight for all purposes by 2050. He made an appearance on the Late Show With David Letterman in 2013 and said we already have enough wind to power the entire world “seven times over."
It's no surprise then that his new house is incredibly eco-friendly. The 3,200-square-foot, three-bedroom, three-bathroom home was designed and built by Canadian prefab homes company BONE Structure. The building is zero-net energy (ZNE), which means that the total amount of energy used by the home equals the amount of energy created on site.
The house runs on 100 percent electricity with the help of rooftop solar, a Tesla Powerwall for energy storage, a Tesla charger for his electric car and Nest appliances. The property doesn't even have gas lines.
"The net energy efficiency, once the envelope is leak-proof, is due not only to the structure but also to energy sources and appliances," Jacobson said. "I have no gas going onto the property; instead, all energy comes from electricity. I will use electric cars, heat pumps for air and water heating, and an electric induction stove. The house will be powered by solar panels on the rooftop and energy will be stored using Tesla batteries in the garage."
Jacobson, who is the head of the Atmosphere and Energy Program at Stanford University, commissioned the company to build his new abode in order to meet his green building standards.
"I study climate and air pollution problems and try to solve them through large scale, clean, renewable energy and I try to practice what I preach," he said.
Jacobson also pointed out that because BONE Structure's homes are prefabricated, it reduces waste, decreases dust and minimizes disruption to neighbors because they are faster to build.
The home’s shell is made of 89 percent recycled steel that is 100 recyclable, seismically resilient (ideal for earthquake-prone California) and safe from damage by termites and mold.
BONE Structure's homes are built from columns and beams that are laser cut in a manufacturing plant, making it endlessly customizable.
“The steel frame system allows for exciting design features that would not be possible using traditional building methods,” Jacobson, who lives on an odd-shaped lot, explained. “Interior spaces and window lines can run up to 25 feet between columns.”
Additionally, as Curbed reported, thanks to a "clip-together design," the frame took less than a week to put together. According to the publication, "another week was spent spraying it with a soy-based foam that, once dry, should provide an airtight envelope that insulates and keeps the steel from shrinking or contracting with the weather."
The house is designed to meet California’s ZNE goal that calls for all new houses in the state to be ZNE by 2020. Jacobson's new residence is the first BONE Structure home in California.
“This is a great first project for BONE Structure in California and a perfect example of the benefits of our system,” Charles Bovet, vice president of BONE Structure, U.S., said. “Stanford is an academically and environmentally focused community and a perfect location for our first net zero home. Our shells are net zero ready, meaning they are extremely energy efficient and with the addition of a small solar system they can produce more energy than they consume.”
The company, which has an office in San Francisco, expects to build 50 more new homes in California this year and is also is scaling up to produce 1,000 residences per year "to address growing demand for this disruptive home construction technology making it the only net zero-ready energy builder that can produce homes on a large scale."

Since 2010, at least 66 million trees have died in California due to drought and rising temperatures, the U.S. Forest Service reported. At last count in October, the death toll was at 40 million trees.
The ongoing, five-year drought in California has made trees increasingly vulnerable to insects and disease and the 65 percent increase in tree die-off has officials concerned about the possibility of a disastrous wildfire season.
“Tree die-offs of this magnitude are unprecedented and increase the risk of catastrophic wildfires that puts property and lives at risk,” said U.S. Agriculture Secretary Tom Vilsack.

In a deal that Elon Musk has dubbed a "no brainer," Tesla Motors has made an offer to acquire solar installation company SolarCity in a stock deal worth a reported $2.8 billion.
The electric car company made the announcement Tuesday and explained the offer in a blog post:
Tesla’s mission has always been tied to sustainability. We seek to accelerate the world’s transition to sustainable transportation by offering increasingly affordable electric vehicles. And in March 2015, we launched Tesla Energy, which through the Powerwall and Powerpack allow homeowners, business owners and utilities to benefit from renewable energy storage.
It’s now time to complete the picture. Tesla customers can drive clean cars and they can use our battery packs to help consume energy more efficiently, but they still need access to the most sustainable energy source that’s available: the sun.
“The world does not look for another car company, the world looks for sustainable energy companies,” Musk told reporters in a conference call on Tuesday.
The prolific entrepreneur is the chairman of SolarCity, which was founded and is operated by his cousins, Lyndon Rive and Peter Rive. Musk is the largest individual shareholder of both companies, with 21.3 percent of Tesla and 22 percent of SolarCity, according to estimates.
SolarCity is the top residential solar installer in the country. Its customers pay for the panels with a monthly fee that's typically less than what they would pay to the power company. A marriage between the two companies would seamlessly tie SolarCity's panels with Tesla's Powerwall batteries. Having a solar-plus-storage system installed by a single company would allow an easier transition to customers to unhook themselves from a carbonized grid.
This morning, in a conference call to reporters and shareholders, Musk further discussed the rationale behind the offer. He said that the idea of consolidating Tesla and SolarCity "has been floated over the years" and it would be “extremely unwieldy” to operate as two companies.
In its blog post, Tesla listed off a number of "significant benefits to our shareholders, customers and employees" if the deal is completed:
- We would be the world’s only vertically integrated energy company offering end-to-end clean energy products to our customers. This would start with the car that you drive and the energy that you use to charge it, and would extend to how everything else in your home or business is powered. With your Model S, Model X, or Model 3, your solar panel system, and your Powerwall all in place, you would be able to deploy and consume energy in the most efficient and sustainable way possible, lowering your costs and minimizing your dependence on fossil fuels and the grid.
- We would be able to expand our addressable market further than either company could do separately. Because of the shared ideals of the companies and our customers, those who are interested in buying Tesla vehicles or Powerwalls are naturally interested in going solar, and the reverse is true as well. When brought together by the high foot traffic that is drawn to Tesla’s stores, everyone should benefit.
- We would be able to maximize and build on the core competencies of each company. Tesla’s experience in design, engineering, and manufacturing should help continue to advance solar panel technology, including by making solar panels add to the look of your home. Similarly, SolarCity’s wide network of sales and distribution channels and expertise in offering customer-friendly financing products would significantly benefit Tesla and its customers.
- We would be able to provide the best possible installation service for all of our clean energy products. SolarCity is the best at installing solar panel systems, and that expertise translates seamlessly to the installation of Powerwalls and charging systems for Tesla vehicles.
- Culturally, this is a great fit. Both companies are driven by a mission of sustainability, innovation, and overcoming any challenges that stand in the way of progress.
“This is what the world needs ... this is Earth’s solution,” Musk said of the merger this morning. Musk has long been a champion solar energy and highly critical of fossil fuels and the fossil fuel industry.
“We have to look back on gas engine cars like we look back on steam engines,” as well as power from fossil fuels, Musk added.
The fact that Musk has the biggest slice of both companies leaves Musk in a bit of an awkward situation, media reports have noted. Electrek explained that the offer to SolarCity "will be contingent on a vote from the shareholders and Musk will abstain from voting his shares due to his vested interest in the deal."
Analysts and investors do not appear happy with the plan. Reuters reported that Tesla’s stock price spiraled more than 13 percent to $189.99 following the announcement yesterday. At the same time however, shares of SolarCity soared about 18 percent to $25.02.
Electrek also observed that shareholders are "calling the deal a 'bailout' of SolarCity, especially after Musk bought another $10 million worth of shares last year—before the stock fell 60 percent in 2016."
SolarCity is also in an ongoing battle against regulators and utilities in states that are unfriendly to rooftop solar, aka the "solar wars" in Nevada over net metering, which allows homeowners to offset the cost of their panels by selling any electricity they don’t use back to the grid. Nevada's NV Energy has been fighting these policies tooth and nail.
Musk, however, shot down the idea of a “bailout” of SolarCity, calling it a “false description.”

Today marks a special day for astronomy enthusiasts. The summer solstice and June's strawberry moon will coincide for the first time in nearly 70 years.
In the Northern Hemisphere, the summer solstice marks the longest day of the year and the official start of summer. The solstice officially starts at 6:34 p.m. ET, the exact time the sun will be in the northernmost position in the sky, directly over the Tropic of Cancer, according to National Geographic.
As the sun sets in the west, the moon will rise in the east. It will fill the sky with rose-tinted light.
This astronomical phenomenon hasn't occurred since 1948, the Baltimore Sun reported.
While the summer solstice and June full moon combination is rare, it is actually mathematically predicted to happen every 15 years, Flarmer's Almanac reported. During a live stream event hosted tonight by the almanac and Slooh, astronomer Bob Berman will discuss why its been so long since the last occurrence.
“Having a full moon land smack on the solstice is a truly rare event," Berman said. “We probably won't push people off pyramids like the Mayans did, but Slooh will very much celebrate this extraordinary day of light with fascinating factoids and amazing live telescope feeds."
The Algonquin tribe called June's full moon the strawberry moon because it marked the time of year they should gather ripening fruit, according to the Farmer's Almanac. In Europe, June's full moon is also known as the Rose or the Honey moon.
Raven Fon wrote an article for The Earth Child suggesting five different ways to celebrate the solstice/full moon combination event. Ideas include:
- Burning herbs. Fon suggests burning any or all of the following herbs to celebrate the solstice: Ruta, Verbena, Misletoe, Lavender, Thyme, Fennel, Plantain, Artemisia or the grass of St. John.
- Drink to the sun. Enjoy a cup of cinnamon or ginger tea to honor the sun and its warmth. Make a celebratory toast.
- Set your intention. Fon said the moon has significant manifestation powers, so this astronomical phenomenon is a great time to set your intention(s). Make a list of things you want to bring into and release from your life. The list can include behaviors, goals and desires.
- Just enjoy the event. The solstice/full moon even is time to be free, Fon wrote. She suggests putting some music on and dancing to express yourself.
- Take a dip. Fon suggests finding a body of water and taking a dip in it. "As full moon pushed and pulls the waters of our Earth, a purification takes place." Taking a dip will rejuvenate and invigorate your soul, she said.
