NASA astronauts Christina Koch, Artemis II mission specialist, and Victor Glover, Artemis II pilot, walk on the crew access arm of the mobile launcher in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Tuesday, Aug. 12, 2025.

On Aug. 11 and 12, teams with the agency’s Exploration Ground Systems Program along with NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, practiced launch day operations if launch occurs at night. They simulated putting their spacesuits on and driving to the launch pad as well as emergency procedures they would use in the unlikely event of an emergency during the launch countdown requiring them to evacuate the launch pad.

Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

Media accreditation is open for the next launch to deliver NASA science investigations, supplies, and equipment to the International Space Station. A Northrop Grumman Cygnus spacecraft will launch to the orbital laboratory on a SpaceX Falcon 9 rocket for NASA.

The mission is known as NASA’s Northrop Grumman Commercial Resupply Services 23, or Northrop Grumman CRS-23. Liftoff is targeted for mid-September from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.

Following launch, astronauts aboard the space station will use the Canadarm2 to grapple Cygnus, and the spacecraft will be installed robotically to the Unity module’s Earth-facing port for cargo unloading. The spacecraft will remain at the space station for more than two months.

Credentialing to cover prelaunch and launch activities is open to U.S. media. The application deadline for U.S. citizens is 11:59 p.m. EDT, Wednesday, Aug. 27. All accreditation requests must be submitted online at:

https://media.ksc.nasa.gov

Credentialed media will receive a confirmation email upon approval. NASA’s media accreditation policy is available online. For questions about accreditation, or to request special logistical support, email: ksc-media-accreditat@mail.nasa.gov. For other questions, please contact NASA’s Kennedy Space Center newsroom at: 321-867-2468.

Para obtener información sobre cobertura en español en el Centro Espacial Kennedy o si desea solicitor entrevistas en español, comuníquese con Antonia Jaramillo o Messod Bendayan a: antonia.jaramillobotero@nasa.gov o messod.c.bendayan@nasa.gov.

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.

NASA Challenge Winners Cook Up New Industry Developments

NASA - Breaking News - Mon, 08/18/2025 - 9:22am

Preparations for Next Moonwalk Simulations Underway (and Underwater) 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.

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.
