Mission Overview

NASA’s SpaceX Crew-11 mission is set to launch a four-person crew to the International Space Station later this summer. Some of the crew have volunteered to participate in a series of experiments to address health challenges astronauts may face on deep space missions during NASA’s Artemis campaign and future human expeditions to Mars.

The research during Crew-11 includes simulated lunar landings, tactics to safeguard vision, and other human physiology studies led by NASA’s Human Research Program.


Research

NASA’s SpaceX Crew-11 mission carries out a wide range of human research studies designed to prepare astronauts for future deep space exploration, including missions to the Moon and Mars. These studies are focused on understanding how long-duration spaceflight affects the human body and how astronauts can adapt to changing gravity environments. The goal is to ensure astronaut safety, performance, and long-term health during and after missions beyond low Earth orbit.

One major area of research involves simulated lunar landings. Crew members will use multi-screen flight simulators and handheld controls to practice piloting a spacecraft under lunar-like conditions before, during, and after the mission. These simulations help scientists assess how shifts in gravity can impact spatial awareness, coordination, and decision-making. A control group on Earth will perform the same simulations to better isolate the effects of microgravity on performance.

Another critical focus is spaceflight-associated neuro-ocular syndrome (SANS), a condition that causes vision and brain changes in some astronauts. Researchers believe it may result from bodily fluids shifting toward the head in microgravity. To study this, astronauts will test whether B vitamin supplements and special thigh cuffs can reduce symptoms. Additional experiments will monitor fluid pressure in the brain and track how the body processes nutrients during spaceflight.

Crew-11 astronauts will also contribute to broader health studies through CIPHER, a suite of tests measuring how different systems in the body respond to spaceflight. These tests include eye exams, MRI scans, and various physiological measurements. Biological samples such as blood and urine will also be collected to investigate genetic changes and help establish medical baselines for future research. Post-flight, astronauts will report any injuries or discomfort from re-entry to inform safer spacecraft design.

All of these experiments are coordinated through NASA’s Human Research Program, which works to develop strategies and technologies that protect astronauts during long-duration missions. By studying the body in space and comparing results to Earth-based controls, NASA can better prepare crews for the challenges of lunar and planetary exploration.

Spacecraft

NASA astronauts Doug Hurley and Bob Behnken, aboard Demo-2, the first crewed mission of the SpaceX Dragon program, named the capsule Endeavour in honor of the Space Shuttle Endeavour, which both had previously flown on. The name symbolizes a legacy of exploration and a new era of human spaceflight.

As with all Crew Dragon vehicles, the name was chosen by the capsule’s first crew following its successful launch on May 30th, 2020.

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: 503

The Falcon 9 has launched 67 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.

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.

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.
