The Crew Dragon is the first privately-developed human orbital spacecraft and is currently the only way NASA and private company Axiom can get astronauts to the International Space Station from US soil. The fleet is comprised of four reusable spacecraft: Endeavour, Resilience, Endurance, and Freedom.

Called Crew Dragon, but known officially as Dragon v2, this SpaceX capsule is designed to carry a maximum of four passengers to the International Space Station or other Earth orbit destinations after being launched atop a reusable Falcon 9 rocket.

The name Endurance is "a tribute to the tenacity of the human spirit, as we push humans and machines farther than we ever have," said NASA Astronaut Raja Chari in the naming announcement for this Crew Dragon.

Dragon for crew

This SpaceX capsule is designed to carry a crew of four to the International Space Station or other Earth orbit destinations after being launched atop a reusable Falcon 9 rocket.

The capsule includes a launch abort system, an advanced environmental control and life support system that keeps the crew safe during flight, and state-of-the-art touchscreen interfaces.

Crew Dragon is designed to operate autonomously but can be manually controlled by SpaceX teams in Hawthorne, California, and the astronauts on board.

Under the contracted crew rotation missions to the Space Station for NASA, Dragon will carry a regular crew of 4 international astronauts.

Crew Dragon is also available for private missions to Earth orbit for paying customers.

For missions to the Station, Crew Dragon can remain in orbit for up to 6 months.

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.

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.

Protecting the Crew

On the launch pad, the crew will board Dragon prior to fueling of the rocket.

Dragon's abort system will be armed and ready to pull the crew away from Falcon 9 in the event a critical issue develops during fueling.

The launch to a 200 x 200 km orbit will take just under 9 minutes.

Dragon and its crew will then separate from the Falcon 9 second stage 11 minutes after liftoff from the Kennedy Space Center.

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.

ISS - Harmony forward

The Harmony module, also known within NASA as Node-2, was launched to the ISS in October 2007 on the STS-120 mission of Shuttle Discovery.

Harmony serves as the gateway between the U.S. scientific and living modules and ESA's Columbus laboratory and JAXA’s Kibo lab complex.

The module is equipped with two docking ports for U.S. crew (Dragon and Starliner) and cargo (Dragon) spacecraft and also has one berthing port that can be used for either Northrop Grumman's Cygnus or Japan's HTV cargo crafts.

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.
