NASA says Growing Plants on International Space Station has applications on Earth
The ability to produce high-energy, low-mass food sources during spaceflight will enable the maintenance of crew health during long-duration missions while having a reduced impact on resources necessary for long-distance travel. ![]() Interior view of the Advanced Astroculture (ADVASC) experiment plant growth chamber showing the emergence of mustard seedlings.

NASA scientists study Aerogel for building habitats on Mars
Raising crops on Mars is far easier in science fiction than it will be in real life: The Red Planet is an inhospitable world. Among other challenges, subzero temperatures mean water can persist on the surface only as ice, and the planet’s atmosphere offers little protection to plants (or people) from the Sun’s radiation. ![]() Scientists are exploring how aerogel, a translucent, Styrofoam-like material, could be used as a building material on Mars. Aerogel retains heat; structures built with it could raise temperatures enough to melt water ice on the Martian surface.

NASA’s Orbiting Carbon Observatory 3 (OCO-3) will study plant growthWritten by Carol Rasmussen
The light is far too dim for us to notice under normal circumstances, but it can be measured with a spectrometer. Called solar-induced fluorescence (SIF), it’s the most accurate signal of photosynthesis that can be observed from space. That’s important because, as Earth’s climate changes, growing seasons worldwide are also changing in both timing and length. ![]() This honeysuckle is glowing in response to a high-energy ultraviolet light rather than to the Sun, but its shine is similar to the solar-induced fluorescence that OCO-3 will measure.

NASA’s ECOSTRESS instrument on International Space Station to study Plant Water usageNASA’s Jet Propulsion Laboratory
That’s about to change, thanks to a new NASA instrument that soon will be installed on the International Space Station called ECOSTRESS, or ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station. ECOSTRESS will measure the temperature of plants from space. This will enable researchers to determine plant water use and to study how drought conditions affect plant health. ![]() ECOSTRESS will measure the temperature of plants from space. Scientists will be able to use that temperature data to better understand how much water plants need and how they respond to water shortages.

Mono-unsaturated fats from plants, not animals may reduce risk of death from heart disease and other causesAmerican Heart Association Meeting Report
![]() The largest reductions in the risk of death were found when healthy fats from plant sources replaced saturated fats, trans fats and refined carbohydrates. (Amnerican Heart Association) «Read the rest of this article» Sections: News | No Comments
Tennessee Department of Agriculture says Buy Locally Grown Flower and Vegetable Plants With Confidence
Experienced plant lovers know that sometimes plants can look beautiful in the store, but will soon wilt once planted. Worse, they can bring bugs and blights into your home. «Read the rest of this article» Sections: News | No Comments
NASA studies Mustard Seedlings roots in microgravity environment on International Space StationWritten by Morgan McAllister
Botanists from Ohio Weslyan University leverage the microgravity environment of the International Space Station to study root growth behaviors and sensory systems in an investigation known as Gravity Perception Systems (Plant Gravity Perception). ![]() Seeds are aligned along a membrane within the cassette and germinated before their exposure to simulated gravity within the EMCS.

NASA Satellites observe Plant Life on Earth’s Land and OceansWritten by Lacey Young
During the week of November 13th-17th, NASA is sharing stories and videos about how this view of life from space is furthering knowledge of our home planet and the search for life on other worlds. ![]() New NASA missions will study terrestrial vegetation, such as these trees along the Kuskokwim River near McGrath, Alaska.

How Does Your Space Garden Grow?Written by Linda Herridge and Amanda Griffin
The Veggie plant growth team kicked it up a notch with their sixth round of crops grown aboard the International Space Station with experiment VEG-03D. For the first time, three different plant varieties are simultaneously growing in the Veggie chamber. ![]() Three different varieties of plants growing in the Veggie plant growth chamber on the International Space Station were harvested this morning.
