SpaceX’s Cargo Dragon spacecraft completed a successful parachute-assisted splashdown off the coast of Florida around 11 p.m. EDT on Thursday, Sept. 30. The capsule undocked from the station’s forward port of the Harmony module Thursday at 9:12 a.m., completing the voyage in approximately 14 hours.
This marked the first time Cargo Dragon splashed down in the Atlantic Ocean. The proximity to the coast of Florida enabled quick transportation of the science aboard the capsule to NASA Kennedy Space Center’s Space Station Processing Facility, delivering some science back into the hands of the researchers hours after splashdown. The shorter transportation timeframe allows researchers to collect data with minimal loss of microgravity effects.
Dragon launched Aug. 29 on a SpaceX Falcon 9 rocket from Launch Complex 39A at Kennedy, arriving at the station the following day. The spacecraft delivered more than 4,800 pounds of research investigations, crew supplies, and vehicle hardware to the orbiting outpost.
A nine-month demolition project for the 25-foot high, 160-foot long, and 135-foot-wide platform, which weighed 9.1 million pounds, was completed last month. Though MLP-2 was a historic piece of equipment, its removal makes way for newer, more advanced technology at the Florida spaceport.
“It was bittersweet having to dismantle MLP-2,” said John Giles, Exploration Ground Systems crawler transporter operations manager. “However, it allows us to make room for newer, more advanced assets to support Artemis missions that will return humans to the Moon and beyond.”
Mobile launcher platforms were used for shuttle missions lifting off from Launch Complex 39A and 39B. These structures did not require a tower since the launch pad had a tower and rotating service structure to allow access to the vehicle.
Since the retirement of the shuttle program, the historic Launch Complex 39A, once the site of Apollo and Saturn V missions, was leased to SpaceX and upgraded to support commercial launches carrying cargo and astronauts into space.
Launch Complex 39B also has changed with the times. It began as an Apollo era structure, was converted for shuttle launches, and now is a clean pad ready to support the Space Launch System (SLS) rocket, carrying the Orion spacecraft as the agency returns to the Moon. When SLS lifts off from pad 39B carrying Orion for the Artemis I mission, it will use the new, advanced mobile launcher that comes with a built-in tower.

While the International Space Station was traveling about 260 miles over Western Australia, a SpaceX Dragon cargo spacecraft autonomously docked to the forward-facing port of the orbiting laboratory’s Harmony module at 10:30 a.m. EDT, Monday, Aug. 30. Flight Engineers Shane Kimbrough and Megan McArthur of NASA monitored operations.
Among the science experiments Dragon is delivering to the space station are:
Building bone with byproducts REducing Arthritis Dependent Inflammation First Phase (READI FP) evaluates the effects of microgravity and space radiation on the growth of bone tissue and tests whether bioactive metabolites, which include substances such as antioxidants formed when food is broken down, might protect bones during spaceflight. The metabolites that will be tested come from plant extracts generated as waste products in wine production. Protecting the health of crew members from the effects of microgravity is crucial for the success of future long-duration space missions. This study could improve scientists’ understanding of the physical changes that cause bone loss and identify potential countermeasures. This insight also could contribute to prevention and treatment of bone loss on Earth, particularly in post-menopausal women.
Keeping an eye on eyes Retinal Diagnostics tests whether a small, light-based device can capture images of the retinas of astronauts to document progression of vision problems known as Space-Associated Neuro-Ocular Syndrome (SANS). The device uses a commercially available lens approved for routine clinical use and is lightweight, mobile, and noninvasive. The videos and images will be downlinked to test and train models for detecting common signs of SANS in astronauts. The investigation is sponsored by ESA (European Space Agency) with the German Aerospace Center Institute of Space Medicine and European Astronaut Centre.
The Nanoracks-GITAI Robotic Arm will demonstrate the microgravity versatility and dexterity of a robot designed by GITAI Japan Inc. Results could support development of robotic labor to support crew activities and tasks, as well as inform servicing, assembly, and manufacturing tasks while in orbit. Robotic support could lower costs and improve crew safety by having robots take on tasks that could expose crew members to hazards. The technology also has applications in extreme and potentially dangerous environments on Earth, including disaster relief, deep-sea excavation, and servicing nuclear power plants. The experiment will be conducted inside the Nanoracks Bishop Airlock, the space station’s first commercial airlock.
Putting materials to the test MISSE-15 NASA is one of a series of investigations on Alpha Space’s Materials ISS Experiment Flight Facility, which is testing how the space environment affects the performance and durability of specific materials and components. These tests provide insights that support development of better materials needed for space exploration. Testing materials in space has the potential to significantly speed up their development. Materials capable of standing up to space also have potential applications in harsh environments on Earth and for improved radiation protection, better solar cells, and more durable concrete.
Helping plants deal with stress
Plants grown under microgravity conditions typically display evidence of stress. Advanced Plant EXperiment-08 (APEX-08) examines the role of compounds known as polyamines in the response of the small, flowering plant thale cress to microgravity stress. Because expression of the genes involved in polyamine metabolism remain the same in space as on the ground, plants do not appear to use polyamines to respond to stress in microgravity. APEX-08 attempts to engineer a way for them to do so. Results could help identify key targets for genetic engineering of plants more suited to microgravity.
Easier drug delivery
The Faraday Research Facility is a multipurpose unit that uses the space station’s EXPRESS payload rack systems, which enable quick, simple integration of multiple payloads . On this first flight, the facility hosts a Houston Methodist Research Institute experiment and two STEM collaborations, including “Making Space for Girls” with the Girl Scouts of Citrus Council in Orlando, Florida.
The Faraday Nanofluidic Implant Communication Experiment (Faraday-NICE) tests an implantable, remote-controlled drug delivery system using sealed containers of saline solution as surrogate test subjects. The device could provide an alternative to bulky, cumbersome infusion pumps, a possible game changer for long-term management of chronic conditions on Earth. Remote-controlled drug delivery could simplify administration for people with limitations.
A partnership between Faraday and Girls Scouts allows troops to play a role in conducting the control experiments, including providing them with images of the same experiments that are happening in space. The studies involve plant growth, ant colonization, and the brine shrimp lifecycle.
These are just a few of the hundreds of investigations currently being conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Advances in these areas will help keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars through Artemis.

NASA is preparing to launch three small, university-built research satellites aboard SpaceX’s 23rd Commercial Resupply Services mission to the International Space Station. This mission, carrying more than 4,800 pounds of cargo, will lift off from NASA’s Kennedy Space Center in Florida Saturday Aug. 28 at 3:37 a.m. EDT.
The small satellites, or CubeSats – built by the Inter-American University of Puerto Rico, University of Illinois Urbana-Champaign, and the University of Massachusetts Lowell – comprise NASA’s 37th Educational Launch of Nanosatellites (ELaNa) mission. Each CubeSat measures approximately four inches by four inches by 12 inches and will carry out unique tasks once deployed into low-Earth orbit.
Puerto Rico CubeSat NanoRocks-2 (PR-CuNaR2) is making history as the first CubeSat from Puerto Rico selected for launch by NASA. The small satellite contains millimeter-sized particles that will be mechanically shaken to induce collisions among the particles. The team hopes that results of the collisions might answer questions about how mass, density, composition of particles, and collision velocities contribute to the formation of protoplanetary disks – disks of gas and dust swirling around stars – and planetary ring systems, such as Saturn’s.
The CubeSat was designed and developed by about 25 students from the School of Engineering at the Bayamón campus of the Inter-American University of Puerto Rico, along with their professor, and principal investigator, Dr. Amilcar Rincón Charris.
Science Program Around Communication Engineering with High Achieving Undergraduate Cadres (SPACE HAUC) is an undergraduate student mission from the University of Massachusetts in Lowell, Massachusetts. SPACE HAUC will demonstrate a student-developed communication system that can quickly transfer large amounts of data. Many CubeSats transfer large data files to ground controllers at 2 to 5 megabits per second. SPACE HAUC aims to increase that speed to about 50 megabits per second using an x-band phased array antenna.
This CubeSat was designed and built over five years and by more than 100 students from the Kennedy College of Sciences and the Francis College of Engineering. Dr. Supriya Chakrabarti, physics professor and director of the Lowell Center for Space Science and Technology, is the principal investigator for this CubeSat mission.
Cool Annealing Payload Satellite (CAPSat) was developed across several departments at the University of Illinois Urbana-Champaign in cooperation with the University of Waterloo in Ontario, Canada. CAPSat will test technology that could enable quantum links in space, which are important for global quantum networks, sensors, and quantum-enhanced telescopes. The demonstration will use a laser to repair single-photon detectors that sense quantum signals.
Over time, photon detectors can become noisy in space due to radiation-induced defects. The laser onboard CAPSat will heat the detector, exciting the atoms in its structure. Once the laser is turned off, the atoms anneal, or settle back into an ordered state, repairing the damage and restoring the detector. The principal investigator, Paul Kwiat, is a professor in the University of Illinois Physics Department.
NASA’s CubeSat Launch Initiative (CSLI) selected the CubeSats, which were assigned to the ELaNa 37 mission by NASA’s Launch Services Program (LSP) based at the Kennedy Space Center in Florida. LSP manages the ELaNa manifest. CSLI provides launch opportunities for small satellite payloads built by universities, high schools, NASA Centers, and non-profit organizations.
To date, NASA has selected 202 CubeSat missions, 119 of which have been launched into space, with 59 more missions scheduled for launch within the next 12 months. The selected CubeSats represent participants from 42 states, the District of Columbia, Puerto Rico, and 102 unique organizations. CSLI recently released its Announcement of Partnership Opportunity for 2021. Applicants can submit CubeSat proposals until Nov. 19, 2021.

On Friday, Aug. 20, teams transported the spacecraft from SpaceX’s processing facility at Cape Canaveral Space Force Station into the hangar at nearby Kennedy Space Center’s Launch Complex 39A, where it was attached to the Falcon 9 rocket two days later.
The rocket – with Dragon atop – was then rolled out to the launch pad Tuesday, Aug. 24, and raised to a vertical position this morning, Aug. 25, in preparation for Saturday’s launch. Liftoff of the Falcon 9 is scheduled for 3:37 a.m. EDT. Dragon will deliver a variety of NASA investigations, including one that will determine if metabolites from grape skins and seeds used in wine-making could help prevent and treat osteoporosis.
About 12 minutes after launch, Dragon will separate from the Falcon 9 rocket’s second stage and begin a carefully choreographed series of thruster firings to reach the space station. Arrival to the orbiting laboratory is planned for Sunday, Aug. 29. The spacecraft is expected to spend about a month attached to the space station before it splashes down off the coast of Florida, returning with research and cargo.
