NASA and SpaceX are launching the company’s 33rd commercial resupply services mission to the International Space Station to deliver science investigations, supplies, and equipment.

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, significantly increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.

In addition to food, supplies, and equipment for the crew, Dragon will deliver several new experiments, including bone-forming stem cells for studying bone loss prevention and materials to 3D print medical implants that could advance treatments for nerve damage on Earth. Dragon also delivers bioprinted liver tissue to study blood vessel development in microgravity and supplies to 3D print metal cubes in space.

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 as we prepare for Mars.

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: 512

Total landings: 467

Total reflights: 436

The Falcon 9 has launched 71 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.

Space Launch Complex 40 (SLC-40) is one of two launch sites leased by SpaceX at Cape Canaveral Space Force Station (CCSFS) in Florida, specifically designed for preparing and launching Falcon 9 rockets. Constructed in the early 1960s, SLC-40 was initially used for 55 Titan III and Titan IV rocket launches, including the Cassini-Huygens mission to Saturn. The pad was active from June 18, 1965, to April 30, 2005.

SpaceX began leasing SLC-40 in 2007, converting it to support Falcon 9 rockets. The pad was first upgraded to accommodate the original version of Falcon 9 and later received another upgrade in 2013 to handle the larger, reusable Falcon 9 rocket. On September 1, 2016, an explosion during a Falcon 9 fueling test caused severe damage to the pad. It was rebuilt rapidly, with construction completed in just 10 months, from mid-February to late November 2017. SLC-40 resumed operations with the successful launch of a Dragon capsule to the International Space Station on December 15, 2017.

After adding a crew access arm to the launch tower, SpaceX launched their first crewed mission from SLC-40 on Saturday, September 28th 2024 for NASA's Crew-9 mission to the International Space Station.

Under SpaceX’s management, SLC-40 has been the site of numerous significant missions. Notable launches include the first all-commercial Dragon mission to the International Space Station, NASA’s DSCOVR mission, the Transiting Exoplanet Survey Satellite (TESS) for NASA and MIT, the first satellite for Turkmenistan, the classified Zuma mission for Northrop Grumman and the U.S. government, the first GPS-III satellite, and the Beresheet lunar lander for Israel. Additionally, in September 2024, SLC-40 will host its first crewed launch with SpaceX’s Crew-9 mission, marking a new milestone for the pad.

Cape Canaveral is a major launch site with four currently active launch pads for Atlas V, Delta IV Heavy, Falcon 9, and Minotaur rockets. Located on Florida’s east coast, it offers extensive access to space for a variety of missions, including those targeting the Space Station, Geostationary Earth Orbit, the Moon, interplanetary destinations, and polar trajectories. The site’s location ensures that launches occur over the open Atlantic Ocean, minimizing risks to populated areas.

Cape Canaveral is often confused with or referred to alongside NASA’s Kennedy Space Center on Merritt Island. While they are separate installations, both play pivotal roles in the U.S. space program. Cape Canaveral has a storied history of significant space missions, including the launch of the first U.S. Earth satellite, Explorer 1, in 1958; the first U.S. astronaut, Alan Shepard, in 1961; the first U.S. astronaut in orbit, John Glenn, in 1962; the launch of the first two-person U.S. spacecraft, Gemini 3, in 1965; and the first U.S. uncrewed lunar landing mission, Surveyor 1, in 1966.

SLC-40 and Cape Canaveral continue to be integral to SpaceX’s ambitious launch schedule and the broader U.S. space program, supporting a wide range of missions and contributing to advancements in space exploration.

The Harmony module (Node 2) is a vital connecting node on the International Space Station, serving as both a passageway between international science modules and a docking hub for visiting spacecraft. It features four pressurized ports, each with a distinct role in supporting ISS operations.

The forward-facing port is equipped with International Docking Adapter-2 (IDA-2) and serves as the primary docking location for both Crew Dragon and Cargo Dragon spacecraft operated by SpaceX, as well as Boeing’s Starliner. The zenith-facing port (pointing toward space) features IDA-3, which acts as a secondary docking port, used when the forward port is unavailable or when mission requirements call for an alternate location. Both ports use the NASA Docking System (NDS), making them compatible with modern U.S. spacecraft.

Harmony’s aft port is permanently connected to the Destiny Laboratory, forming the structural backbone of the U.S. segment. The starboard port links to Japan’s Kibo module, and the port-side connection leads to Europe’s Columbus module. Together, these ports support international science and logistics, while the forward and zenith ports ensure ongoing access for both crew and cargo missions. Harmony plays a crucial role in maintaining the ISS as a fully operational, continuously crewed orbital laboratory.

LZ-2

Landing Zone 2 (LZ-2) is an 85 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.

The landing pad, as well as its twin, LZ-1 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.
