NASA astronaut Scott Kelly took this majestic image of the Earth at night highlighting the green and red hues of an Aurora. NASA NASA is asking American companies to provide input on the agency’s requirements for end-to-end services as part of the Commercial Low-Earth Orbit Development Program.
In the future, the agency plans to transition its operations in low Earth orbit to commercially owned and operated destinations to ensure continued access and presence in space for research, technology development, and international collaboration after the planned retirement of the International Space Station.
Through a request for information (RFI), NASA is seeking feedback from industry as the agency refines its anticipated requirements for new commercial space destinations. The requirements will help industry understand NASA’s human-rating standards that will be used by the agency to certify that the new systems meet NASA expectations for low Earth orbit operations and transportation. An industry briefing day is scheduled to take place Tuesday Oct. 12, with responses to the RFI due Wednesday, Nov. 17.
“This RFI is a significant next step in transitioning low Earth orbit operations to the private sector, allowing NASA to be one of many customers for services” says Phil McAlister, director of commercial spaceflight at NASA Headquarters in Washington, D.C. “These requirements will be the foundation upon which the companies can design safe systems. But the requirements have to work for companies as well. Thus, we are seeking industry feedback on these draft requirements to ensure that the Commercial LEO destinations will be safe, reliable, and cost effective.”
The agency is currently supporting the development of several new stations and destination concepts through both funded and unfunded agreements. However, a company does not need to have a current agreement with NASA in order to provide feedback via the RFI or to bid on future procurements to provide low Earth orbit services to the agency.
“We’ve seen a tremendous amount of innovation and effort from industry thus far in developing their station designs,” says Angela Hart, manager of the Commercial Low Earth Orbit Development program at NASA’s Johnson Space Center in Houston. “We are working in lockstep with multiple companies to help guide them in a way that sets them up for success to meet our requirements. However, it’s crucial that we open feedback to as wide of an audience as possible. The more commercial stations that are successfully operating in low Earth orbit, the greater likelihood that we can continue to drive down costs and encourage innovation in this new commercial space industry.”
NASA previously sought industry input in 2022 and early 2023, and has hosted two industry days on the agency’s assumptions and expectations for crew and technical requirements to guide companies’ technical and business plans. The feedback from industry will continue to inform the agency’s future commercial services strategy for low Earth orbit destinations.
NASA’s goal is to enable a strong commercial marketplace in low Earth orbit where NASA is one of many customers for private industry. This strategy will provide services the government needs safely, at a lower cost, and enables the agency to focus on its Artemis missions to the Moon in preparation for Mars, while continuing to use low Earth orbit as a training and proving ground for those deep space missions.
Information about how to attend the industry briefing day is contained in the RFI on SAM.gov. The dates for industry day and responses due are subject to change pending a government shutdown resolution and will be updated on SAM.gov when available.

SpaceX’s Dragon will deliver new science investigations, food, supplies, and equipment to the international crew. The research includes work to understand interactions between weather on Earth and space, and laser communications. NASA’s Atmospheric Waves Experiment (AWE) will study atmospheric gravity waves –powerful waves formed by weather disturbances on Earth such as strong thunderstorms or brewing hurricanes – to understand the flow of energy through Earth’s upper atmosphere and space. Another experiment – Integrated Laser Communications Relay Demonstration Low-Earth-Orbit User Modem and Amplifier Terminal – (ILLUMA-T) aims to test high data rate laser communications from the space station to Earth. This will complete NASA’s first two-way, end-to-end laser relay system by sending high-resolution data to the agency’s Laser Communications Relay Demonstration, which launched in December 2021.
Other investigations that will launch with the resupply mission include ESA’s (European Space Agency) Aquamembrane-3, which will test water filtration using proteins found in nature for water recycling and recovery, and Plant Habitat-06, which will evaluate the effects of spaceflight on plant defense responses using multiple genotypes of tomato.
Commercial resupply by U.S. companies significantly increases NASA’s ability to conduct more investigations aboard the orbiting laboratory. These investigations lead to new technologies, medical treatments, and products that improve life on Earth. Other U.S. government agencies, private industry, and academic and research institutions can also conduct microgravity research through the agency’s partnership with the International Space Station National Laboratory.
Humans have occupied the space station continuously since November 2000. In that time, 273 people and a variety of international and commercial spacecraft have visited the orbital outpost. It remains the springboard to NASA’s next great leap in exploration, including future missions to the Moon under Artemis, and ultimately, human exploration of Mars.

NASA logo Credit: NASA NASA has selected SpaceX of Hawthorne, California, and its Falcon 9 rocket to provide the launch service for the agency’s TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission, a pair of small satellites that will study space weather and how the Sun’s energy affects Earth’s magnetic environment, or magnetosphere
TRACERS will be an important addition to NASA’s heliophysics fleet and aims to answer long-standing questions critical to understanding the Sun-Earth system. The spinning satellites will study how solar wind, the continuous stream of ionized particles escaping the Sun and pouring out to space, interacts with the region around Earth dominated by our planet’s magnetic field. This interaction, or magnetic reconnection, is an intense transfer of energy that can happen when two magnetic fields meet, which could potentially impact operations with crew and sensitive satellites. TRACERS is led by the University of Iowa with partners at the Southwest Research Institute in San Antonio, and Millennium Space Systems in El Segundo, California.
NASA’s Launch Services Program, based out of the agency’s Kennedy Space Center in Florida, in partnership with NASA’s Heliophysics Small Explorers program, announces the launch service as part of the agency’s VADR (Venture-Class Acquisition of Dedicated and Rideshare) launch services contract.

Crew members aboard the International Space Station conducted a variety of scientific investigations during the week ending Sept. 29, 2023, including FLARE.
This JAXA (Japan Aerospace Exploration Agency) investigation explores the flammability of materials in microgravity. Current tests of materials that are used in crewed spacecraft do not consider gravity, which significantly affects combustion phenomena. The ability for flames to spread over solid materials, for example, is affected by the forces of buoyancy, which are absent in microgravity. Removing the effects of buoyancy by conducting combustion experiments in microgravity also gives researchers a better understanding of specific flame behaviors.
JAXA astronaut Satoshi Furukawa sets up hardware for the FLARE investigation. NASA Other investigations on the space station have examined the behavior, spread, and growth of fire. This work helps guide selection of spacecraft cabin materials, improve understanding of early fire growth behavior, validate models used to determine material flammability, and identify optimal fire suppression techniques. Developing ways to prevent and extinguish fire is of critical importance to the safety of crew members and vehicles in space and in confined spaces such as aircraft on Earth. These settings limit the options for suppressing fires and can be difficult to evacuate from.
Burning and Suppression of Solids (BASS) was one of the first investigations to examine how to extinguish a variety of fuels burning in microgravity. Putting out fires in space must consider the geometry of the flame and characteristics of the materials and methods used to extinguish it, as those used on the ground could be ineffective or even make the flame worse. Analysis of 59 BASS burn tests provided data on heat flow, flame size, effects of fuel mixture flow, and other important parameters.
BASS-II examined the burning and extinction characteristics of a variety of fuel samples to test the hypothesis that materials burn as well if not better in microgravity than in normal gravity, given adequate ventilation and identical conditions such as pressure, oxygen concentration, and temperature. A number of papers have been published based on results from BASS-II, with findings including a report on the differences between flame spread and fuel regression and comparison of flame spread rates.

NASA Solid Fuel Ignition and Extinction – Growth and Extinction Limit (SoFIE-GEL), a research collaboration between NASA and Roscosmos, analyzes how the temperature of a fuel affects material flammability. Researchers report that experimental observations agree with trends predicted by the models. This investigation is the first in a series using the SoFIE insert for the station’s Combustion Integrated Rack.
ESA (European Space Agency) astronaut Samantha Cristoforetti works on the SoFIE-GEL investigation of materials flammability.NASA Saffire is a series of experiments conducted aboard uncrewed Cygnus cargo spacecraft after they depart the station. Using these cargo vehicles provides distance from the crewed station and enables tests of larger fires. Results have shown that a flame spreading over thin fabrics in microgravity reaches a steady spread rate and a limiting length, which can be used to establish the rate of heat release in a spacecraft, and found that reducing pressure slows down the flame spread.
A sample of fabric burns inside an uncrewed Cygnus cargo craft for the Saffire-IV experiment. NASA Confined Combustion, sponsored by the ISS National Lab, examines the behavior of flame spread in confined spaces of different shapes. Confinement has been shown to have significant effects on fire characteristics and hazards. Researchers report specifics on interactions between a flame and its surrounding walls and the fate of the flame, such as growth or extinction. These data provide guidance for design of structures and fire safety codes and response in space and on Earth. Other results suggest that confinement can increase or decrease solid fuel flammability depending on conditions. Researchers also demonstrated that color pyrometry – capturing flame emission simultaneously at three broad spectral bands – can determine the temperature of a flame without disrupting its spread.
Flame studies help keep crews in space and people on Earth safe. This research also can lead to more efficient combustion, reducing impurities and producing greener and more efficient flames for uses on Earth such as heating and transportation.
