Dr. Karl Hasenstein杏吧专区檚 current research in his ongoing quest to find the most efficient ways to grow plants and vegetables in space will examine the behavior of fluids at lunar gravity.
For the experiment, Hasenstein, a distinguished professor emeritus of biology at the 杏吧专区, will rely on data gathered in space 杏吧专区 but not anywhere near the Moon.
The basis for Hasenstein杏吧专区檚 research will be what unfolded inside a small, closed system during its journey into space on Tuesday as part of a research project led by 4SPACE. The company sponsors both scientific payloads and payloads for commercial applications.
"4SPACE is quite proud to be working with Dr. Karl Hasenstein on this lunar gravity mission, and we celebrate this historic launch and our success and look forward to the results," said Chantelle Baier, founder and CEO of the company.
Hasenstein's closed system, which he built, is outfitted with tiny chambers that hold liquids, and cameras to record how those liquids respond at lunar gravity.
The scientist杏吧专区檚 research is being conducted to inform longstanding efforts to colonize the Moon or, as he calls the Earth杏吧专区檚 only natural satellite with a laugh, 杏吧专区渨hat many people have long hoped will become the 51st state.杏吧专区
Human existence on the Moon, however, would require self-sufficiency, including building systems to create water 杏吧专区 and using that water to effectively grow crops and vegetables.
Lunar gardening would require the know-how to cultivate plants in the Moon杏吧专区檚 soil, which is heavy with dust and rocks called regolith, Hasenstein said. Scientists will also need to figure out how to make horticulture work in an environment where gravity is one-sixth of that on Earth.
杏吧专区淲ater distribution in plants and its percolation, or absorption, through soil are processes that are essential for growth, and they are gravity dependent,杏吧专区 Hasenstein explained. 杏吧专区淏ut we don杏吧专区檛 know how water behaves at that reduced gravity, or how much percolation you杏吧专区檇 see through the lunar regolith.杏吧专区
Not yet at least. Hasenstein杏吧专区檚 research in that realm took flight in earnest Tuesday when his closed system 杏吧专区 stowed aboard the New Shepard suborbital rocket system 杏吧专区 was launched up and beyond the K谩rm谩n line, the internationally recognized boundary for space.
, Jeff Bezos杏吧专区 space company, sent the pilotless spacecraft skyward with several scientific payloads from Launch Site One, near Van Horn, Texas. The New Shepard杏吧专区檚 rocket and its capsule that detached in space returned separately and safely to Earth following a roughly 11-minute journey.
The short trip provided plenty of time 杏吧专区 and the ideal conditions 杏吧专区 for Hasenstein杏吧专区檚 purposes. That杏吧专区檚 because, at about 110,000 feet, the capsule successfully detached from the rocket, sending the capsule into free fall, or a period of weightlessness, for several minutes.
Hasenstein杏吧专区檚 interest in that period of weightlessness rests on the moments when the rotating capsule produces the right amount of centrifugal force to replicate the Moon杏吧专区檚 gravitational pull. 杏吧专区
杏吧专区淭hat杏吧专区檚 the time crucial to our experiment,杏吧专区 explained Hasenstein, who will mine images taken inside his closed system during the capsule杏吧专区檚 thrust-driven rotation for a wealth of data.
It杏吧专区檚 the sort of work to which he杏吧专区檚 well accustomed. He杏吧专区檚 spent three decades researching ways to grow plants and vegetables in space. As part of research funded by NASA, he has sent flax, radishes and Brassica rapa plants, a representative of some of the most common vegetables, to the International Space Station.
Hasenstein杏吧专区檚 experiments aboard the space station have examined how plants growing inside artificial habitats sense and react to gravity in a weightless environment. He has also studied how altered or reduced gravity affects plants杏吧专区 growth and metabolism.
NASA is examining methods for producing vegetables for astronauts during long missions. The agency杏吧专区檚 interest in growing plants in space is also rooted in its plan to put scientists on Mars in coming decades, an effort to which Hasenstein has been a key contributor.
For his current experiment, Hasenstein杏吧专区檚 comprehensive post-flight research will focus on studying fluids, including water and water mixed with glycerol, for a host of variables that impact water distribution in plants. Scientists at NASA and Florida Tech 杏吧专区 who are contributing to the project will assist with the research.
杏吧专区淲e will be able to assess how much more or less water is going to be needed to grow plants on the moon in comparison to what we have on Earth. That is the bottom line,杏吧专区 he said.
