Astronauts will attempt to grow mushrooms in space for the first time during SpaceX's upcoming Fram2 mission.
Launching aboard a SpaceX Falcon 9 rocket as early as Monday (March 31), the Fram2 mission will be the first human spaceflight mission to fly over Earth's polar regions. It will carry a crew of four into a 90-degree orbit that will send them over both the North and South Poles.
The Fram2 crew will attempt to grow oyster mushrooms in microgravity as part of an experiment called Mission MushVroom, which is led by the Australian company FOODiQ Global. Mushrooms could offer a nutritious, delicious and sustainable food source for long-duration missions to the moon, Mars and beyond, according to a statement from the company.
"Mushrooms are the perfect space crop," FOODiQ Global CEO Flávia Fayet-Moore, who's leading the experiment, said in the statement.
"Oyster mushrooms rapidly grow in small spaces, doubling in size daily, and are packed with a rich nutrient profile," added Fayet-Moore, who's also a space nutritionist. "Uniquely, they produce 100% of astronauts' daily dose of vitamin D when exposed to UV light, potentially replacing one of the key supplements currently given to them on the International Space Station."

The Fram2 mission is led by Maltese entrepreneur Chun Wang. The other crewmembers include vehicle commander Jannicke Mikkelsen of Norway, Australia's Eric Philips, who's the medical officer and mission specialist, and pilot Rabea Rogge of Germany. This will be the first spaceflight for all four crewmembers.
During the planned three-to-five-day SpaceX mission, the crew will conduct a series of research experiments centered around astronaut health, for which proper nutrition is key. The mushroom experiment will be conducted on the last day of the mission, led by Philips.
"In space, food often tastes bland due to altered taste perception and the need for a low-sodium diet to help counteract the negative effects of microgravity on bone health," Flávia said in the statement. "Mushrooms are rich in umami flavor, being one of the only tastes that remains strong in space. Oyster mushrooms are also highly resilient, scalable and capable of growing using 100% of the inedible plant waste, and even cotton t-shirts in their growth medium."
As part of the MushVroom experiment, the crew will prepare the oyster mushroom substrate and study its fruiting process, which is essential for releasing new spores to allow the fungus to produce mushrooms.

The astronauts will closely monitor the development rate of the mushrooms (the fruiting bodies), look for signs of contamination and analyze various other growth characteristics. Following the mission, scientists at FOODiQ Global will analyze the mushrooms grown in space to study the effects of microgravity and compare the samples to those grown on Earth.
"Successfully growing edible mushrooms in space represents a significant milestone for space exploration and sustainable nutrition," Ralph Fritsche, former space crop production/exploration food systems project manager for NASA and lead subject matter expert for NASA's Deep Space Food Challenge, said in the statement. "Mission MushVroom plays a crucial role in advancing sustainable space food production for long-duration missions — such as journeys to Mars — and offers valuable insights that can enhance global food security here on Earth. It really is groundbreaking."

Amazon launches second batch of Kuiper internet satellites, taking on Elon Musk's Starlink
Amazon's second batch of Kuiper internet satellites reached low Earth orbit on Monday, adding to its plans for a massive constellation and ramping up competition with SpaceX's Starlink. A United Launch Alliance rocket carrying 27 Kuiper satellites lifted off from a launchpad at the Cape Canaveral Space Force Station in Florida at 6:54 a.m. ET, according to a livestream. "We have ignition and lift off of United Launch Alliance Atlas V rocket carrying satellites for Amazon's Project Kuiper internet constellation, continuing a new chapter in low Earth orbit satellite connectivity," Ben Chilton, an ordnance engineer at ULA, said on the livestream following the launch. Monday's mission was rescheduled twice, owing to inclement weather and a problem with the rocket booster. Six years ago, Amazon unveiled its plans to build a constellation of internet-beaming satellites in low Earth orbit, called Project Kuiper. The service will compete directly with Elon Musk's Starlink, which currently dominates the market and has 8,000 satellites in orbit. Amazon in April successfully sent up 27 Kuiper internet satellites into low Earth orbit, a region of space that's within 1,200 miles of the Earth's surface. The 54 craft currently in orbit are the start of Amazon's planned constellation of 3,236 satellites. The company has to meet a Federal Communications Commission deadline to launch half of its total constellation, or 1,618 satellites, by July 2026. The company has booked more than 80 launches with several providers, including rival SpaceX, to deliver Kuiper its satellites into orbit.

The treasure trove of platinum on the moon
When you buy through links on our articles, Future and its syndication partners may earn a commission. The moon is likely to become the next mining hot spot, as there may be extensive platinum and other metal deposits in its craters. Guidelines about resource mining on the moon are still not solidified, so this could lead to problems with more countries and private companies trying to stake their claim. But the potential for platinum could also entice private companies to invest more in space exploration. There might be more than $1 trillion worth of platinum deposits on the moon, according to a paper published in the journal Planetary and Space Science. Of the 1.3 million craters on the moon with a diameter greater than one kilometer, "nearly 6,500 were made by asteroids containing commercial quantities of platinum," said New Scientist. This "highlights the potential viability and profitability of lunar mining endeavors compared to mining asteroids in orbit," said the paper. Countries have already been involved in a modern space race to put humans back on the moon, and the profit potential could bring more interested parties. Nobody owns the moon because of the Outer Space Treaty of 1967. But as the potential for resources becomes imminent, the rules are likely to change. The treaty notably "leaves key questions unanswered," Rebecca Connolly, an adjunct senior lecturer at the University of Sydney Law School, said to New Scientist. This includes "clarity on the rules and governance for ownership of extracted resources, commercial licensing rights, equitable benefits sharing, environment protection standards to avoid harm, and regulations for long-term occupation and permanent infrastructure on the moon." To address some of the unknowns, NASA and the U.S. spearheaded the Artemis Accords in 2020. These "provide a common set of principles to enhance the governance of the civil exploration and use of outer space," said NASA. Though the accords are nonbinding, 55 countries have signed on as of last month. Russia and China, two of the most proactive countries trying to reach the moon, have not signed on. A monetary incentive for reaching the moon could change space exploration as we know it. Astronomy is "done to satiate our curiosity," Jayanth Chennamangalam, an astrophysicist and the lead author of the study, said to New Scientist. It has "very few practical applications" and is "mostly paid for by taxpayer money." If we can "monetize space resources, be it on the moon or on asteroids, private enterprises will invest in the exploration of the solar system." While that could lead to wider research being done, it can also lead to the exploitation of the moon. It was recently listed as a threatened historic site for this very reason. "Take one last good look at the moon tonight," Luis Prada said at Vice. "There might be a time when the moon is not so innocent and pretty anymore and you only see cynical corporate greed."

Watch Live: ULA tries for 2nd launch of year on mission for Amazon
United Launch Alliance took a week to reset, but will try again to send up its second launch of the year, another mission for Amazon's effort to compete with SpaceX's Starlink internet constellation. An Atlas V rocket on the Kuiper-2 mission with 27 internet satellites is targeting a 6:54 a.m. liftoff from Cape Canaveral Space Force Station's Space Launch Complex 41 during a 30-minute window. The launch attempt comes one week since ULA scrubbed because of bad temperature readings on the rocket related to a gaseous nitrogen purge line. 'Sorted the issue,' said ULA President and CEO Tory Bruno calling it an unintentional wet dress rehearsal. While ULA is only making its second launch of the year, SpaceX earlier Monday morning launched its 50th mission from the Space Coast. A Falcon 9 lifted off from Canaveral's nearby Space Launch Complex 40 at 1:58 a.m. with 27 Starlink satellites. The first-stage booster flew for the 25th time landing on the droneship A Shortfall of Gravitas. SpaceX has now launched more than 9,000 Starlink satellites since 2019. For ULA, the Atlas V is one of only 14 left in ULA's stable, seven of which are set aside for Amazon as the company looks to get more than 3,200 of its Project Kuiper satellites into orbit by 2028. ULA's first launch of the year in April was also for Amazon sending up the constellation's first 27 operational satellites. The company also purchased an additional 38 launches on ULA's new Vulcan rocket as well as missions on Blue Origin, Arianespace and even SpaceX. In total, Amazon has lined up more than 80 flights as it tries to play catchup to SpaceX, which has launched close to 9,000 of its Starlink satellites since 2019. While the satellites are manufactured in Washington, Amazon has built a $120 million satellite processing facility at a nearly 80-acre site at the Kennedy Space Center's former Shuttle Landing Facility where they will get the final preparations for launch such as fueling. For now, ULA is the only company proliferating the constellation, and Vulcan has the lion's share of contracted missions. ULA has only flown its Vulcan rocket twice so far, both in 2024, but is expecting to fly it a third time as early as July on a national security mission for the Space Force. ULA President and CEO Tory Bruno said that after that mission, Vulcan would fly its first Project Kuiper flight, one during which Vulcan would have six solid rocket boosters in its most powerful configuration. After that, Amazon missions will jump back and forth between Vulcan and remaining six contracted Atlas V rockets. Vulcan rockets have a larger capacity than Atlas V and would be able to carry 45 Project Kuiper satellites per launch. Amazon has a goal of getting more than half of the planned constellation into orbit before July 2026 as part of requirements put forth by its Federal Communications Commission license. To increase launch cadence, ULA has been building out a second vertical integration facility in Cape Canaveral so it can prepare two rockets for launch at the same time. Its goal is to ramp up to at least two launches per month on the Space Coast. It also has launch capability from California. ULA had only five launches total in 2024 including the final Delta IV Heavy launch from Space Launch Complex 37. SpaceX under the direction of the Space Force demolished the launch tower at SLC-37 last week in preparation to build out new launch facilities to support its in-development Starship and Super Heavy rockets. While SpaceX will continue launches from SLC-40 and Kennedy Space Center, ULA will focus its Space Coast operations entirely from SLC-41. ULA still has seven other Atlas V rockets set aside for other customers. One is for communications company ViaSat and six are assigned to Boeing Starliner launches, so the final flight for Atlas V may not come until as late as 2030. ULA has a backlog of more than 70 missions including 24 for national security. Its Vulcan rocket was only certified for those launches this spring after years of the delays in the rocket's development. Bruno has said ULA would like to ramp up to at least 24 launches per year by the end of 2026. The company formed as a partnership between Boeing and Lockheed Martin in 2006 and had been the primary launch provider for national security missions until SpaceX joined the competition. The most missions the company has flown in a single year has been 16 in 2009.
