Crunchy algae, anyone? NASA shares ideas for food in space

Add as a preferred source on Google

From bugs to algae, and from 3D printing to artificial photosynthesis, NASA has announced a plethora of ideas about what the future of food in space could look like. The agency recently held a challenge asking organizations and members of the public to submit their most daring concepts of how to feed astronauts on space missions.

NASA’s Deep Space Food Challenge invited chefs, small businesses, and students to submit their innovative ideas about how to develop food for astronauts, with the winning teams receiving a prize of $25,000 each.

Some of the winning entries included growing microalgae and dehydrating them into “crunchy bite-sized snacks;” generating foods from insect cells to be eaten in place of meat products; creating a symbiotic system of algae, yeast, mushrooms, and plants which would grow in 3D-printed artificial soil; an artificial photosynthetic system; and a microbial system which uses “plastic and biomass waste as the carbon source for food generation.”

As bizarre and perhaps unappetizing as some of these ideas might sound, being open-minded about different food sources is important for keeping astronauts both mentally and physically healthy on long-duration space missions.

“NASA is excited to engage the public in developing technologies that could fuel our deep space explorers,” said Jim Reuter, associate administrator for NASA’s Space Technology Mission Directorate, in a statement. “Our approach to deep space human exploration is strengthened by new technological advances and diverse community input. This challenge helps us push the boundaries of exploration capabilities in ways we may not recognize on our own.”

The development of unusual food products and food systems is not only useful for astronauts on space missions. With increasing environmental challenges requiring new approaches to agriculture, they could also benefit all of us here on Earth.

“These types of food systems could offer benefits on our home planet,” said Robyn Gatens, director of the International Space Station Program at NASA and challenge judge. “Solutions from this challenge could enable new avenues for worldwide food production in resource-scarce regions and locations where disasters disrupt critical infrastructure.”

If you’re interested in learning more about the competition, the winning entries, and the issue of food in space, then NASA will air a show all about the challenge on November 9 at 11 a.m. ET (8 a.m. PT). You can watch online it by heading over to NASA TV’s website.

Virgin Galactic is charging $750,000 for three minutes of weightlessness, and nearly 700 people are already in the queue
Three minutes of floating, one very expensive ticket.

I’ll be honest with you. Three minutes of weightlessness for the price of a very nice house sounds absurd to me. Even so, hundreds of people have already lined up to experience it.

Most recently, Virgin Galactic unveiled Apeiron, the first spaceplane in its new Delta class. The company flew it from its Arizona factory to Spaceport America in New Mexico, where it will begin flight testing.

After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.
