This is the 23rd spacecraft built to deliver goods to the International Space Station. In March, NASA and Northrop Grumman moved up the company’s Commercial Resupply Services-23 mission to September following damage to the Cygnus Pressurized Cargo Module during shipping for the company’s Commercial Resupply Services-22 flight.
Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.
In addition to food, supplies, and equipment for the crew, Cygnus will deliver research, including materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. Cygnus also will deliver a specialized UV light system to prevent biofilm growth and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For almost 25 years, humans have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration of the Moon and Mars.

NuCLEUS, developed by Interstellar Lab, is an autonomous system that grows microgreens, vegetables, and more for astronauts to eat in space.Interstellar Lab NASA invests in technologies that have the potential to revolutionize space exploration, including the way astronauts live in space. Through the Deep Space Food Challenge, NASA, in partnership with CSA (Canadian Space Agency), sought novel food production systems that could provide long-duration human space exploration missions with safe, nutritious, and tasty food. Three winners selected last summer are now taking their technology to new heights – figuratively and literally – through commercial partnerships.
Interstellar Lab of Merritt Island, Florida, won the challenge’s $750,000 grand prize for its food production system NuCLEUS (Nutritional Closed-Loop Eco-Unit System), by demonstrating an autonomous operation growing microgreens, vegetables, and mushrooms, as well as sustaining insects for use in an astronaut’s diet. To address the requirements of the NASA challenge, NuCLEUS includes an irrigation system that sustains crop growth with minimal human intervention. This end-to-end system supplies fresh ingredients to support astronauts’ health and happiness, with an eye toward what the future of dining on deep space missions to Mars and the Moon may look like.
Since the close of the challenge, Interstellar Lab has partnered with aerospace company Vast to integrate a spinoff of NuCLEUS, called Eden 1.0, on Haven-1, a planned commercial space station. Eden 1.0 is a plant growth unit designed to conduct research on plants in a microgravity environment using functions directly stemming from NuCLEUS.
“The NASA Deep Space Food Challenge was a pivotal catalyst for Interstellar Lab, driving us to refine our NuCLEUS system and directly shaping the development of Eden 1.0, setting the stage for breakthroughs in plant growth research to sustain life both in space and on Earth,” said Barbara Belvisi, founder and CEO of Interstellar Lab.
Fuanyi Fobellah, one of the “Simunauts” from The Ohio State University who tested food production technologies as part of the Deep Space Food Challenge, removes a cooked omelet from the SATED appliance.NASA/Savannah Bullard Team SATED (Safe Appliance, Tidy, Efficient & Delicious) of Boulder, Colorado, earned a $250,000 second prize for its namesake appliance, which creates an artificial gravitational force that presses food ingredients against its heated inner surface for cooking. The technology was developed by Jim Sears, who entered the contest as a one-person team and has since founded the small business SATED Space LLC.
At the challenge finale event, the technology was introduced to the team of world-renowned chef and restaurant owner, José Andrés. The SATED technology is undergoing testing with the José Andrés Group, which could add to existing space food recipes that include lemon cake, pizza, and quiche. The SATED team also is exploring partnerships to expand the list of ingredients compatible with the appliance, such as synthetic cooking oils safe for space.
Delicious food was a top priority in the Deep Space Food Challenge. Sears noted the importance of food that is more than mere sustenance. “When extremely high performance is required, and the situations are demanding, tough, and lonely, the thing that pulls it all together and makes people operate at their best is eating fresh cooked food in community.”
Team Nolux won a $250,000 second-place prize for its Nolux food system that uses artificial photosynthesis to grow ingredients that could be used by astronauts in space.OSU/CFAES/Kenneth Chamberlain Team Nolux, formed from faculty members, graduate, and undergraduate students from the University of California, Riverside, also won a $250,000 second prize for its artificial photosynthesis system. The Nolux system – whose name means “no light” – grows plant and fungal-based foods in a dark chamber using acetate to chemically stimulate photosynthesis without light, a capability that could prove valuable in space with limited access to sunlight.
Some members of the Nolux team are now commercializing select aspects of the technology developed during the challenge. These efforts are being pursued through a newly incorporated company focused on refining the technology and exploring market applications.
A competition inspired by NASA’s Deep Space Food Challenge will open this fall.

NASA’s 1991 Discovery shuttle video shows UFOs making impossible maneuvers, evading a possible Star Wars railgun test. Evidence of secret tech?
In September 1991, NASA’s Space Shuttle Discovery transmitted live video that has since become one of the most debated UFO clips ever recorded. The footage, later analyzed by independent researchers, shows glowing objects in orbit performing maneuvers far beyond the limits of known physics.
One object appears over Earth’s horizon, drifts smoothly, then suddenly reacts to a flash of light by accelerating at impossible speeds, estimated at over 200,000 mph while withstanding forces of 14,000 g’s. NASA officially dismissed the anomalies as ice particles or debris, but side by side comparisons with actual orbital ice show key differences: the objects make sharp turns, sudden accelerations, and fade in brightness in ways consistent with being hundreds of miles away, not near the shuttle.
Image analysis expert Dr. Mark Carlotto confirmed that at least one object was located about 1,700 miles from the shuttle, placing it in Earth’s atmosphere. At that distance, the object would be too large and too fast to be dismissed as ice or space junk.
The flash and two streaks seen in the video resemble the Pentagon’s “Brilliant Pebbles” concept, a railgun based missile defense system tested in the early 1990s. Researchers suggest the shuttle cameras may have accidentally, or deliberately, captured a live Star Wars weapons test in orbit.
The UFO easily evaded the attack, leading some to conclude that it was powered by a form of hyperdimensional technology capable of altering gravity.
Notably, following this 1991 incident, all subsequent NASA shuttle external camera feeds were censored or delayed, raising speculation that someone inside the agency allowed the extraordinary footage to slip out.

Human-rating is a critical certification process that validates the safety, reliability, and suitability of space systems—including orbiters, launch vehicles, rovers, spacesuits, habitats, and other crewed elements—for human use and interaction. This process ensures that systems are designed not only to protect human life but also to accommodate human needs and effectively integrate human capabilities. Human-rating requires that systems can tolerate failures, provide life-sustaining environments, and offer the crew sufficient control and situational awareness. NASA’s standards, such as a maximum allowable probability of loss of crew of 1 in 500 for ascent or descent, reflect the agency’s commitment to minimizing risk in human spaceflight.
Over the decades, the concept of human-rating has evolved significantly. Early efforts focused primarily on basic crew survival and redundancy in critical systems. However, as missions became more complex and extended in duration, the scope of human-rating expanded to include human performance, health management, and the psychological and physiological demands of space travel. Today, human-rating is a multidisciplinary effort that integrates engineering, medical, and operational expertise to ensure that systems are not only survivable but also support optimal human function in extreme environments.
Modern human-rating standards—such as NASA Procedural Requirements (NPR) 8705.2C, NASA-STD-8719.29 (Technical Requirements for Human-Rating), and NASA-STD-3001 (Human System Standards)—form the foundation of NASA’s approach. These documents emphasize risk-informed design, fault tolerance, human factors engineering, and the ability to recover from hazardous situations. They also provide detailed guidance on system safety, crew control interfaces, abort capabilities, and environmental health requirements. Together, they ensure that human spaceflight systems are designed to accommodate, utilize, and protect the crew throughout all mission phases.
The human-rating certification process is rigorous and iterative. It involves extensive testing, validation, and verification of system performance, including simulations, flight tests, and integrated safety analyses. Certification also requires continuous monitoring, configuration control, and maintenance to ensure that systems remain in their certified state throughout their operational life. Importantly, human-rating is not just a checklist of technical requirements—it represents a cultural commitment to crew safety. It fosters a mindset in which every team member, from design engineers to mission operators, shares responsibility for protecting human life.
To support program and project teams in applying these standards, NASA has conducted cross-reviews of documents like NASA-STD-3001 in relation to NASA-STD-8719.29. These assessments help identify relevant human health and performance requirements that should be considered during system design and development. While not a substitute for detailed applicability assessments, such reviews provide valuable guidance for integrating human-rating principles into mission planning and vehicle architecture.
