SUPPORTFor the NG-21 mission, the Cygnus spacecraft will deliver more than 3,700 kg. (8,200 lb.) of cargo to the International Space Station. Cygnus is comprised of two primary components, the Pressurized Cargo Module and the Service Module.
In keeping with company tradition, each spacecraft is named after an important figure in the aerospace industry. Northrop Grumman is honored to name the NG-21 Cygnus spacecraft after NASA astronaut Francis R. "Dick" Scobee, an accomplished astronaut and pilot who lost his life in 1986 when he commanded the Challenger.
The S.S. Francis R. "Dick" Scobee will be launched into orbit using a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Northrop Grumman will once again load critical, time-sensitive cargo into Cygnus 24 hours before the scheduled launch.
Upon arrival at the International Space Station, the cargo will be unloaded from Cygnus. First conducted on the NG-17 mission, Cygnus offers the capability to perform routine reboost services as needed while berthed to the station. Once its mission has been completed, Cygnus will perform a safe, destructive reentry into Earth’s atmosphere.

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.

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.

After launch, Cygnus will spend a few days boosting itself up to the International Space Station. When it arrives, two crew members will grab it with the Station's robotic arm, Canadarm2, and berth it to the Earth-facing, or Nadir, port on the Unity module.
Unity, also called Node-1, was the second module of the ISS to be launched. Taken to orbit on the STS-88 mission of Shuttle Endeavour, Unity was joined to the Russian Zarya ("dawn") module on December 6th, 1998.
The Unity nadir port hosted two Space Shuttle dockings on the STS-97 and STS-98 missions of the Shuttles Endeavour and Atlantis in December 2000 and February 2001.
Since December 2015, it has been the only berthing port used for the Cygnus cargo spacecraft.

After a multi-day orbital chase, Cygnus will be grappled by the Station's Canadarm2 and berthed to the Harmony module's (Node-2's) Earth-facing nadir Common Berthing port.

SLC-40 was built in the early 1960s and hosted its first launch on June 18, 1965. Since then, it has launched nearly 100 missions on the Titan III, Titan IV, and Falcon 9 rockets.
During the Titan rocket era, SLC-40 was used to launch two interplanetary missions: Mars Observer to Mars and Cassini-Huygens to Saturn.
With the Falcon 9, the pad became the first Cape Canaveral site to host a launch to the International Space Station.
The pad is located on historic Cape Canaveral Air Force Station, FL - the primary launch center for the United States.
The Florida launch site handles the vast majority of U.S. launches every year and has been the starting point of numerous history-making missions for the United States, including:
