Earlier this month, NASA astronaut Kate Rubins photographs the first major milestone of the Plant Habitat-02 (PH-02) experiment aboard the International Space Station. The investigation studies the growth of radishes in a microgravity environment. NASA chose the radish because it’s a model plant: both…

Self-sufficiency is a goal of many liveaboard cruisers who sail the world’s oceans, generating their own water and power, writes Erin Carey With limited space and the obvious challenges of salt, wind and motion, many would never entertain the idea of growing their own produce. Yet it can be possible: we spoke to cruisers who…

The future colonization of the Moon and Mars will be conditioned by the possibility of guaranteeing the production of food on their surfaces. Taking a kilo of tomatoes (or any other product) to the Earth's satellite costs a million euro, so eating a salad in space is a very expensive luxury. Therefore, this is currently a…

Experts say food production needs to increase by 70 per cent in the next 30 years to feed a world population expected to reach 9 billion people. Unfortunately, traditional agriculture is facing increasing scarcity of water due to climate change. Freshwater accounts for only 2 per cent of all water on…

Pietro Alberti, an entrepreneur from Arica, received the support of the Luksic Foundation's Impulso Chileno program to launch an ambitious project: growing tomatoes in a greenhouse in the Atacama desert, the driest desert in the world. One of the biggest difficulties he faced when developing the project…

Norwegian researchers develop new cultivation method, inspired by NASA's Mars colonies

Norwegian researchers are testing a new greenhouse cultivation method which emits very little gas. Norwegian, and global food production, is, after all, a major source of emissions. That's mainly because growers use artificial fertilizers and non-recyclable raw materials. Ketil Stoknes very recently…

Scientists: Worms Could Kill Pests on Space Vegetables

Space Worms

If long-term missions to space or even new worlds are to have any chance of success, astronauts will likely need to learn to grow their own food.

That means developing a space version of agriculture. Now, scientists from the U.S. Department of Agriculture and the biotech company Pheronym brought the idea one step closer to reality with the discovery that roundworms are just as good at gobbling up pest insects up in space as they are down here, giving future astronauts a new way to protect their crops.

Space Nematodes: A Giant Leap for Interplanetary Agriculture - Agricultural Research

In a successful return-to-space mission, research study results indicate that beneficial insect-killing nematodes (small round worms) can be used in the future for natural control of insect pests when humans are growing crops in space. The research objective was to study entomopathogenic (insect-killing) nematodes (EPNs) foraging and infection dynamics in space onboard the International Space Station (ISS) between December 2019 and January 2020.

These beneficial roundworms may have "what it takes" for controlling pest insects that threaten crops grown aboard during long-term human missions in space. That's the implication of findings from experiments conducted aboard the ISS and published in the journal npj|Microgravity. EPNs are insect parasites used to naturally control insect pests that damage crops, that's why investigating the efficacy of EPNs in a unique environment like the one provided by the ISS (e.g. an apparent state of weightlessness) could help establish successful agriculture and plant protection in space.

How to design a sustainable greenhouse in Middle Eastern and North African climate

Food security is currently one of the main goals in the Middle East and North Africa. They strive to become self-sufficient. These countries often face harsh conditions, with hot and dry or hot and wet climates. The main issue there isn't how to heat the greenhouse, but how to cool and dehumidify it.  With…

The increased salinity of soils, both due to the use of chemical products in agriculture and to climate change, is one of the factors that limit plant development.

NASA Experiment: Radishes Could Probably Grow in Lunar Soil

NASA scientist Max Coleman has been trying to figure out if it’s possible to grow radishes in lunar soil — in his kitchen.

His goal is to figure out whether astronauts could one day grow their own food on the lunar surface — much like Matt Damon’s character in Ridley Scott’s 2015 film “The Martian.”

Coleman chose radishes because “they have been used before in space, and they germinate very, very fast,” according to a NASA Jet Propulsion Lab (JPL) statement.
