Scientists Are Devising Clever Solutions to Feed Astronauts on Mars Space Flights

Astronaut and Expedition 64 Flight Engineer Soichi Noguchi of the Japan Aerospace Exploration Agency displays Extra Dwarf Pak Choi plants growing aboard the International Space Station. The plants were grown for the Veggie study which is exploring space agriculture as a way to sustain astronauts on future missions to the Moon or Mars.

Astronauts at the International Space Station today depend on pre-packaged, freeze-dried food, plus some fresh produce thanks to regular resupply missions. This supply chain, however, will not be available on trips further out, such as the moon or Mars. So what are astronauts on long missions going to eat?

Going by the options available now, says Christel Paille, an engineer at the European Space Agency, a lunar expedition is likely to have only dehydrated foods. “So no more fresh product, and a limited amount of already hydrated product in cans.”

For the Mars mission, the situation is a bit more complex, she says. Prepackaged food could still constitute most of their food, “but combined with [on site] production of certain food products…to get them fresh.” A Mars mission isn’t right around the corner, but scientists are currently working on solutions for how to feed those astronauts. A number of boundary-pushing efforts are now underway.

She Put the First Rover on Mars, Breaking the Glass Ceiling for Women at NASA

When NASA's Perseverance rover landed successfully on Mars on February 18, 2021, calling it "one giant leap for mankind" – as Neil Armstrong said when he set foot on the moon in 1969 – would have been inaccurate. This year actually marked the fifth time the U.S. space agency has put a remote-controlled robotic exploration vehicle on the Red Planet. And it was a female engineer named Donna Shirley who broke new ground for women in science as the manager of both the Mars Exploration Program and the 30-person team that built Sojourner, the first rover to land on Mars on July 4, 1997.

For Shirley, the Mars Pathfinder mission was the climax of her 32-year career at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California. The Oklahoma-born scientist, who earned her Master's degree in aerospace engineering from the University of Southern California, saw her profile skyrocket with media appearances from CNN to the New York Times, and her autobiography Managing Martians came out in 1998. Now 79 and living in a Tulsa retirement community, she still embraces her status as a female pioneer.

EVENT INFORMATION

DATE:

Thursday, March 11th, 2021 at 12:30pm - 1:45pm EST

On the one-year anniversary of the global declaration of the pandemic, this virtual event will convene leading scientific and medical experts to discuss the most pressing questions around the COVID-19 vaccines. Planned topics include the effect of the new circulating variants on the vaccines, what we know so far about transmission dynamics post-vaccination, how individuals can behave post-vaccination, the myths of "good" and "bad" vaccines as more alternatives come on board, and more. A public Q&A will follow the expert discussion.
