CRS-31 Experiments

Robotic spacecraft guidance

Smartphone Video Guidance Sensor-2 (SVGS-2) uses the space station’s Astrobee robots to demonstrate using a vision-based sensor developed by NASA to control a formation flight of small satellites. Based on a previous in-space demonstration of the technology, this investigation is designed to refine the maneuvers of multiple robots and integrate the information with spacecraft systems.

Potential benefits of this technology include improved accuracy and reliability of systems for guidance, navigation, and control that could be applied to docking crewed spacecraft in orbit and remotely operating multiple robots on the lunar or Martian surface.

Protection from particles

During spaceflight, especially long-duration missions, concentrations of airborne particles must be kept within ranges safe for crew health and hardware performance. The Aerosol Monitors investigation tests three different air quality monitors in space to determine which is best suited to protect crew health and ensure mission success. The investigation also tests a device for distinguishing between smoke and dust. Aboard the space station, the presence of dust can cause false smoke alarms that require crew member response. Reducing false alarms could save valuable crew time while continuing to protect astronaut safety.

Better materials, better drugs

The DNA Nano Therapeutics-Mission 2 produces a special type of molecule formed by DNA-inspired, customizable building blocks known as Janus base nanomaterials. It also evaluates how well the materials reduce joint inflammation and whether they can help regenerate cartilage lost due to arthritis. These materials are less toxic, more stable, and more compatible with living tissues than current drug delivery technologies.

Environmental influences such as gravity can affect the quality of these materials and delivery systems. In microgravity, they are larger and have greater uniformity and structural integrity. This investigation could help identify the best formulations and methods for cost-effective in-space production. These nanomaterials also could be used to create novel systems targeting therapy delivery that improves patient outcomes with fewer side effects.

Next-generation pharmaceutical nanostructures

The newest Industrial Crystallization Cassette (ADSEP-ICC) investigation adds capabilities to an existing protein crystallization facility. The cassette can process more sample types, including tiny gold particles used in devices that detect cancer and other diseases or in targeted drug delivery systems. Microgravity makes it possible to produce larger and more uniform gold particles, which improves their use in research and real-life applications of technologies related to human health.

Helping plants grow

Rhodium USAFA NIGHT examines how tomato plants respond to microgravity and whether a carbon dioxide replacement can reduce how much space-grown plants depend on photosynthesis. Because photosynthesis needs light, which requires spacecraft power to generate, alternatives would reduce energy use. The investigation also examines whether using supplements increases plant growth on the space station, which has been observed in preflight testing on Earth. In future plant production facilities aboard spacecraft or on celestial bodies, supplements could come from available organic materials such as waste.

Understanding how plants adapt to microgravity could help grow food during long-duration space missions or harsh environments on Earth.

Atomic clocks in space

An ESA (European Space Agency) investigation, Atomic Clock Ensemble in Space (ACES), examines fundamental physics concepts such as Einstein’s theory of relativity using two next-generation atomic clocks operated in microgravity. Results have applications to scientific measurement studies, the search for dark matter, and fundamental physics research that relies on highly accurate atomic clocks in space. The experiment also tests a technology for synchronizing clocks worldwide using global navigation satellite networks.

Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond.

Falcon 9 is the world’s first orbital-class reusable rocket.

Stats

Completed missions: 458

Total landings: 413

Total reflights: 385

The Falcon 9 has launched 62 humans into orbit since May 2020

Specs

Height: 70 m / 229.6 ft

Diameter: 3.7 m / 12 ft

Mass: 549,054 kg / 1,207,920 lb

Payload to Low Earth Orbit (LEO): 22,800 kg / 50,265 lb

Payload to Geostationary Transfer Orbit (GTO): 8,300 kg / 18,300 lb

Payload to Mars: 4,020 kg / 8,860 lb

On January 24, 2021, Falcon 9 launched the first ride-share mission to Sun Synchronous Orbit. It was delivering a record-setting 143 satellites to space. And while this was an important mission for SpaceX in itself, it was also the moment Falcon 9 overtook United Launch Alliance’s Atlas V for the total number of consecutive successful launches.

SpaceX’s Falcon 9 had become America’s workhorse rocket, launching 31 times in 2021. It has already beaten that record this year, launching almost an average of once a week. While most of the launches deliver Starlink satellites to orbit, the company is still launching the most commercial payloads to orbit, too.

Falcon 9 is a medium-lift launch vehicle, with the capability to launch over 22.8 metric tonnes to low earth orbit. Unlike any other rocket, its first stage lands back on Earth after separating from its second stage. In part, this allows SpaceX to offer the cheapest option for most customers with payloads that need to reach orbit.

Under its ride-share program, a kilogram can be placed in a sun-synchronous orbit for a mere 1.1 million dollars, far cheaper than all other currently operating small satellite launch vehicles.

The reusability and fast booster turnaround times have made Falcon 9 the preferred choice for private companies and government agencies. This has allowed SpaceX to capture a huge portion of the launch market.

Launch Complex 39A (LC-39A) is a historic launch site located at NASA's Kennedy Space Center in Florida. Originally constructed in the late 1960s, LC-39A was designed to support the Apollo program, including the groundbreaking Apollo 11 mission that first landed humans on the Moon in 1969. The pad also played a crucial role in launching Skylab missions and was instrumental during the Space Shuttle era, including the launch of the first Space Shuttle, Columbia, on STS-1 in 1981.

In 2014, SpaceX leased LC-39A from NASA and undertook extensive refurbishments to adapt the pad for its Falcon 9 and Falcon Heavy rockets. These upgrades involved significant modifications to the pad's infrastructure to meet the requirements of SpaceX’s rockets. Since then, LC-39A has become a vital launch site for SpaceX, supporting a range of missions including crewed flights under NASA's Commercial Crew Program.

Under SpaceX's management, LC-39A has been the site of several landmark events. It hosted the first Falcon 9 launch from the pad on March 30, 2017, and was the launch site for the historic Falcon Heavy debut on February 6, 2018, which was the most powerful rocket in operation at that time. Additionally, LC-39A was the launch site for the first crewed flight of the Crew Dragon spacecraft on May 30, 2020, marking the first crewed spaceflight from U.S. soil since the end of the Shuttle program.

Today, LC-39A remains a critical asset for SpaceX, supporting both crewed and uncrewed missions. It continues to serve as a launch site for Falcon 9 and Falcon Heavy rockets and is expected to play a central role in future missions, including those aimed at lunar exploration and beyond. The pad's rich history and ongoing significance highlight its importance in the broader context of space exploration.

LZ-1

Landing Zone 1 (LZ-1) is an 86 meter wide circular landing pad at the Cape Canaveral Space Force Station and is one of two SpaceX booster landing pads at the Florida spaceport.

Built on former Launch Complex 13, LZ-1 was the site of SpaceX's first successful landing and recovery of a Falcon 9 on the ORBCOMM-2 mission in December 2015. Since then, it has hosted 16 landings.

The landing pad, as well as its twin, LZ-2 located a few dozen meters away, can support both single landings of a Falcon 9 or simultaneous landings of the two Falcon Heavy side boosters.
