NASA is sending astronauts back to the Moon by the end of this decade, and hope to send humans to Mars sometime in the 2030s. Growing food in space using in-situ resources is vital if astronauts are to survive on both the Moon and Mars for the long-term. Growing plants in space using Earth soil is nothing new, as this research is currently ongoing onboard the International Space Station (ISS). But recent research carried out on Earth has taken crucial steps in being able to grow food in space using extraterrestrial material that we took from the Moon over 50 years ago.Continue reading “Plants can grow in lunar regolith, but they’re not happy about it”
First Space Zinnia Blooms and Catches Sun’s Rays on Space Station
The first Zinnia flower to bloom in space is dramatically catching the sun’s rays like we have never seen before – through the windows of the Cupola on the International Space Station (ISS) while simultaneously providing a splash of soothing color, nature and reminders of home to the multinational crew living and working on the orbital science laboratory.
Furthermore its contributing invaluable experience to scientists and astronauts on learning how to grow plants and food in microgravity during future deep space human expeditions planned for NASA’s “Journey to Mars” initiative.
NASA astronaut and Expedition 46 Commander Scott Kelly is proudly sharing stunning new photos showing off his space grown Zinnias – which bloomed for the first time on Jan. 16, all thanks to his experienced green thumb.

A Salad Bar for the Space Station
Freeze-dried bags of dehydrated “astronaut food” may seem like a fun novelty for school kids on Earth, but despite all the hard work that goes into providing the residents of the Space Station with nutritious and varied meal options there’s one thing that remains a rare and elusive commodity on astronauts’ menus: fresh produce.
Although fruit and vegetables do occasionally find their way aboard the ISS via resupply missions (to the delight of the crew) researchers are moving one step closer to actually having a vegetable garden in orbit. On
Monday, April 14 Friday, April 18, NASA’s Veg-01 experiment will launch to the ISS aboard a SpaceX Dragon capsule to test the in-flight viability of an expandable plant growth chamber named “Veggie.”
In development for several years, Veggie is now getting its chance to be space-tested with the launch of the SpaceX-3 resupply mission. Veggie uses clear collapsible bellows as miniature greenhouses, inside which plant “pillows” can be cultivated with the aid of root-mats and a bank of LED lights.
Astronauts will see how well “Outredgeous” romaine lettuce fares in microgravity inside the Veg-01 experiment, and can also use the LED bank as a light source for other experiments.
“Veggie will provide a new resource for U.S. astronauts and researchers as we begin to develop the capabilities of growing fresh produce and other large plants on the space station,” said Gioia Massa, the NASA payload scientist for Veggie. “Determining food safety is one of our primary goals for this validation test.”
While other plant-growth experiments are currently aboard ISS, Veggie boasts the simplest design and largest growing area of any of them to date.
“Our hope is that even though VEGGIE is not a highly complex plant growth apparatus, it will allow the crew to rapidly grow vegetables using a fairly simple nutrient and water delivery approach.”
– Howard Levine, Ph.D. and chief scientist at Kennedy Space Center (2012)
In addition to providing fresh food, maintaining a miniature garden in orbit would be therapeutic for astronauts on long-duration missions.
“Based upon anecdotal evidence, crews report that having plants around was very comforting and helped them feel less out of touch with Earth,” Massa said. “You could also think of plants as pets. The crew just likes to nurture them.”
The Veggie system was developed for NASA by Orbital Technologies Corporation (ORBITEC) in Madison, Wisconsin, via a Small Business Innovative Research Program. Its innovations may eventually lead to better food production not only in space but also in limited-resource regions on Earth.
With the ultimate success of Veggie, ISS astronauts may soon find themselves floating in line at the in-house salad bar. (Watch out for those rogue croutons!)

NASA Looks at 3-D Food Printer for Star Trek-like Replicator
The International Space Station may soon have its very own Star Trek food replicator.
Earlier this week, NASA awarded a $125,000 six month grant to the Systems & Materials Research Cooperation to design a 3D printer capable of printing a pizza from 30-year shelf stable foodstuffs.
Founded by Anjan Contractor, SMRC built a basic food printer from a chocolate printer to win NASA’s Small Business Innovation Research Program in a trial video. The design is based on an open-source RepRap 3D printer.
Contractor and SMRC will begin construction on the pizza-printing prototype in two weeks. Pizza has been one item missing from astronauts menu for years. The 3D printer would “build-up” a pizza serving by first layering out the dough onto a heated plate then adding tomato sauce and toppings.
But this isn’t your mother’s pizza, as the proteins would be provided by cartridge injectors filled with organic base powders derived from algae, insects and grass.
Yummy stuff, to be sure!
Of course, one can see an immediate application of 3D food printing technology for long duration space missions. Contractor and SMRC envisions 3D food printing as the wave of the future, with the capacity to solve world hunger for a burgeoning human population.
Could a 3D food printer be coming to a kitchen near you?
Curiously, printing confectioneries and pet food pellets would be the simplest application of said technology. Printing a soufflé and crowned rack of lamb will be tougher. 3D printing technology has made great strides as of late, and RepRap has made a printer which is capable of printing itself. Those who fear the rise of Von Neumann’s self-replicating robots should take note…
Should we welcome or fear our self-replicating, pizza-bearing overlords?
The International Space Station is due for the delivery of its first 3D printer in 2014. This will give astros the capability to fabricate simple parts and tools onsite without requiring machining. Of course, the first question on our minds is: How will a 3D printer function in zero-g? Will one have tomato paste an insect parts flying about? Recent flights aboard a Boeing 727 by Made in Space Inc have been testing 3D printers in micro-gravity environments.
Further afield, 3D replicators may arrive on the Moon or Mars ahead of humans, building a prefab colony with raw materials available for colonists to follow.
Will 3D food replicators pioneered by SMRC be a permanent fixture on crewed long duration space missions? Plans such as Dennis Tito’s Mars 2018 flyby and the one way Mars One proposal will definitely have to address the dietary dilemmas of hungry astronauts. Biosphere 2 demonstrated that animal husbandry will be impractical on long term missions. Future Martian colonists will definitely eat much farther down the food chain to survive. SpaceX head Elon Musk has recently said in a Twitter response to PETA that he won’t be the “Kale Eating Overlord of Mars,” and perhaps “micro-ranching” of insects will be the only viable alternative to filet mignon on the Red Planet. Hey, it beats Soylent Green… and the good news is, you can still brew beer from algae!
Would YOU take a one way journey to Mars? Would you eat a bug to do it? It’ll be interesting to watch these 3D printers in action as they take to space and print America’s favorite delivery fast food. But it’s yet to be seen if home replicators will put Dominos Pizza out of business anytime soon. Perhaps they’ll only be viable if they can print a pizza in less than “30 minutes!”
