NASA astronaut Tracy C. Dyson displays from JAXA (Japan Aerospace Exploration Agency) food packets in the International Space Station galley.Credits: NASA NASA recently welcomed more than 50 commercial food and commercial space companies to learn about the evolving space food system supporting NASA missions, including unique requirements for spaceflight, menu development, and food provisioning – essential elements for human spaceflight and sustainable living in space.
The event, held at the agency’s Johnson Space Center in Houston, brought together private industry leaders, NASA astronauts, and NASA’s space food team to discuss creative solutions for nourishing government and private astronauts on future commercial space stations.
“The commercial food industry is the leader in how to produce safe and nutritious food for the consumer, and with knowledge passed on from NASA regarding the unique needs for space food safety and human health, this community is poised to support this new market of commercial low Earth orbit consumers,” said Kimberlee Prokhorov, deputy chief for the Human Systems Engineering and Integration Division at Johnson, which encompasses food systems work.
Experts from NASA’s Space Food Systems Laboratory shared the unique requirements and conditions surrounding the formulation, production, packaging, and logistics of space food for enabling the success of commercial low Earth orbit missions. Attendees heard astronaut perspectives on the importance of space food, challenges they encounter, and potential areas of improvement. They also tasted real space food and learned about the nutritional requirements critical for maintaining human health and performance in space.
“By bringing together key players in the commercial food and space industries, we were able to provide a collaborative opportunity to share fresh ideas and explore future collaborations,” said Angela Hart, manager for NASA’s Commercial Low Earth Orbit Development Program at Johnson. “Space food is a unique challenge, and it is one that NASA is excited to bring commercial companies into. Working with our commercial partners allows us to advance in ways that benefit not only astronauts but also food systems on Earth.”
As NASA expands opportunities in low Earth orbit, it’s essential for the commercial sector to take on the support of space food production, allowing the agency to focus its resources on developing food systems for longer duration human space exploration missions.
NASA will continue providing best practices and offer additional opportunities to interested commercial partners to share knowledge that will enable a successful commercial space ecosystem.
The agency’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost and enable the agency to focus on Artemis missions to the Moon in preparation for Mars, while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

Proba-3 is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3’s Coronagraph spacecraft observe the Sun’s faint surrounding atmosphere, the disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3’s Occulter ends up facing the Sun continuously, making it a valuable platform for science in its own right.

Bundling the Best of Heliophysics Education: DigiKits for Physics and Astronomy Teachers
For nearly a decade, the American Association of Physics Teachers (AAPT) has been working to bring together resources through its DigiKits–multimedia collections of vetted high-quality resources for teachers and their students. These resources are toolkits, allowing teachers to pick and choose interesting content to support their instruction. As a partner with the NASA Heliophysics Education Activation Team (HEAT), this work has directly supported the bundling of digital content around heliophysics lessons created by the AAPT team.
As an example, AAPT’s most recent DigiKit publication, Auroral Currents Science (Figure 1), was developed for educators of advanced high school students and university physics/astronomy majors. DigiKits materials are collected by digital content specialist, Caroline Hall, who searches for high-quality, open digital content and checks it for accuracy and accessibility. The Auroral Currents DigiKit centers around a lecture tutorial that gives students the opportunity to practice and extend their knowledge of magnetic fields produced by current-carrying wires, and relating those understandings to auroral currents – the primary phenomenon underlying the dramatic auroral light shows seen in the sky over the past months.
The corresponding DigiKit includes a collection of relevant simulations, videos/animations, and other teacher resources for background that can help to teach the content in the primary lesson. The DigiKit highlights NASA’s forthcoming Electrojet Zeeman Imaging Explorer (EZIE) mission, including an animation of the relationship between the Earth and space, an explanation of Earth’s electrojets and a visualization of the spacecraft. It also includes links to NASA’s ongoing Magnetospheric Multiscale spacecraft video explanation of magnetic reconnection, among many other useful resources that can be shown in the classroom or explored individually by students. Unique to this DigiKit are recent science news articles covering 2024’s spectacular auroral displays.
The light in the aurora comes from atoms in the ionosphere that have been excited by collisions with electrons that were accelerated between 6000 km and 20000 km above Earth’s surface. Those electrons carry electric currents from space along the magnetic field, but the currents flow horizontally some distance through the ionosphere at about 100-150 km in altitude before returning to space. We call those currents the ionospheric electrojets, and we can see the magnetic effects of the electrojets because electric currents are the source of magnetic fields. The AAPT digikit allows students to explore the magnetic signature of the electrojets and determine the size and location of the currents.
As a result of participation in NASA HEAT, AAPT has produced ten DigiKits, all linked below and available alongside the collection of other tutorials/core resources on the AAPT NASA HEAT page. Although the DigiKits are directed toward teachers, and the lessons are intended for standard classroom contexts, the resources can also be a great introduction to NASA-related concepts and modern science ideas for the general public.

A strange image has been circulating across social media in Thailand, showing a large, dark pillar-like structure mysteriously appearing in the sky over Ubon Ratchathani. According to the photographer, the picture was taken on Sunday, October 20, 2024, while they were trying to capture the "beautiful, colorful sky.
This peculiar sighting isn't entirely unprecedented. Similar strange phenomena have been reported before. On October 7, 2015, a mysterious "floating city" with skyscrapers appeared in the clouds over Foshan, Guangdong province in China. Again, on March 18, 2016, ghostly buildings were seen above the sea along the port of Dalian, in Liaoning Province, China, lingering in the sky for several minutes.
Most recently, on September 11, 2020, an eerie image resembling the Hogwarts School from Harry Potter was spotted hovering over modern buildings in Jinan, Shandong Province. On July 14, 2022, a bizarre occurrence was also witnessed by residents in Haikou, Hainan, where a mysterious floating city appeared in the sky.
Scientists suggest that these events are most likely optical illusions, with mirages being the leading theory. Mirages occur when light rays bend, causing distant objects or parts of the sky to appear displaced. One specific type, known as a Fata Morgana, can create towering, distorted images of distant objects, contributing to these surreal sights.
Although the sightings between 2015 and 2022 were witnessed by many, the photographer in Thailand later realized that the mysterious pillar hadn't been visible to the naked eye at the time. This discovery has led some to speculate that the phenomenon might have been caused by a Project Blue Beam test, holographic technology, or even a temporary vortex connected to a parallel universe.
