ClassX Video Lessons Youtube Channel Curiosity Stream The Successful Launch and Landing of the Dragon | Flight of the Dragon [Mission Update]
For nearly a decade, the United States has relied on Russia to maintain its presence on the International Space Station (ISS) due to the absence of a domestic space shuttle alternative. This dependency has come at a significant financial cost, with the U.S. spending nearly $4 billion on rides aboard Russian Soyuz rockets. The ISS is a vital asset for the U.S., making access to it crucial.
Returning these missions to American soil marks a significant milestone, offering an alternative to the Soyuz solution. As an American, there is a sense of pride in once again launching from U.S. soil. The last crew launch from the U.S. was in 2011, and resuming these missions is a profound step forward. This mission signifies a pivotal change in how America approaches space travel. Unlike previous missions, NASA will not own or operate the spacecraft; instead, it will act as a customer, utilizing the Dragon and Starliner programs. This approach provides redundancy, a critical factor in spaceflight.
Upon the successful completion of this test mission, the Dragon spacecraft will be cleared for official crew missions, while the Starliner will continue its development. SpaceX has been successfully transporting cargo to the ISS with the Dragon since 2012, completing 20 cargo missions. In 2019, SpaceX conducted the first test of the Crew Dragon to the ISS. During the Demo-1 mission, the Crew Dragon, without a crew, autonomously docked with the ISS and returned safely, marking a historic achievement.
The current mission, NASA’s SpaceX Demo-2, is the final major test to certify SpaceX’s innovative crew transportation system for extended missions to the ISS. This mission ensures that the Dragon can safely transport astronauts. This flight is historic, as it uses a brand-new spacecraft, a feat achieved only five times in history, following the Mercury, Gemini, Apollo, and Space Shuttle programs.
The rocket propelling the Crew Dragon into space is a critical component of the mission, following the legacy of the Saturn V rocket, which took Apollo astronauts to the moon. The Saturn V remains the most powerful rocket ever built, generating 7.6 million pounds of thrust at launch. The Space Shuttle, introduced in 1981, was the first reusable spacecraft, launching with rocket boosters and gliding back to Earth. The Crew Dragon, like the Apollo missions, is a free-flying spacecraft launched atop a rocket. The SpaceX Falcon 9 rocket, standing 23 stories tall, delivers nearly 2 million pounds of thrust.
The Dragon’s flight profile differs from that of the Shuttle. During the transition from the first to the second stage of the Falcon 9, there is a brief period of weightlessness followed by a G-force of over four Gs, compared to the Shuttle’s limit of 3 Gs. Launching humans atop any rocket involves inherent risks, necessitating a robust escape plan. Extensive engineering tests were conducted, including activating the launch escape system to ensure the Dragon can safely evacuate the crew in an emergency.
Years of rigorous testing and test flights have been conducted to cover every aspect of this mission. SpaceX has visited the ISS 21 times, marking a new chapter in U.S. space exploration, albeit with significant risks and challenges. Boeing’s Starliner faced a near-disaster during a 2019 unmanned flight test due to a software glitch but managed to return safely to Earth. SpaceX has reached a major milestone, overcoming numerous challenges over 18 years. Initially, SpaceX estimated only a 10% chance of reaching orbit, achieving it on the fourth attempt with Falcon 1. Despite several test failures in recent years, the lessons learned have been invaluable. It is crucial to remember that this is a test flight, and safety remains the top priority.

[Music] Without a space shuttle alternative, the United States has depended on Russia to maintain an American presence on the International Space Station for the past nine years. We have been purchasing rides on Russian Soyuz rockets, and those costs have increased significantly, totaling nearly $4 billion. The International Space Station is a critical capability for the United States, and having access to it is essential.
Bringing these missions back to American soil is significant, especially as an alternative to the Soyuz solution. As an American, I am proud of what we will accomplish by flying again on an American rocket from American soil. It’s remarkable to think that the last time a crew launch vehicle departed from the United States was in 2011. It would be profound to be back in the saddle again and to launch frequently. This mission demonstrates a remarkable role reversal for how America goes to space. This time, we are doing it differently than ever before. NASA will not purchase, own, or operate the hardware; instead, we will be a customer with both the Dragon and Starliner programs in development. NASA has redundancy, which is crucial in all aspects of spaceflight.
Once this test mission is complete, Dragon will be cleared for official crew missions, and Starliner will continue its development. SpaceX has been transporting cargo on Dragon to the ISS since 2012, successfully completing 20 cargo missions. They also completed the first test run of the all-new Crew Dragon to the ISS in 2019. Last year, we had our Demo-1 mission, where the Crew Dragon, without any crew on board, went to the space station, opened the hatch, and returned home. Demo-1 marked the first time in history that a spacecraft docked autonomously without assistance from the mother ship.
This new mission, known as NASA’s SpaceX Demo-2, is the final major test to certify SpaceX’s revolutionary crew transportation system for long-duration missions to the ISS, ensuring that Dragon can safely transport passengers. This historic flight uses a brand new spacecraft, marking the fifth time in history we have put humans on a brand new spacecraft, following notable predecessors like Mercury, Gemini, Apollo, and the Space Shuttle.
The rocket that will take Crew Dragon into space is one of the most critical components of the mission, following a standard set by the Saturn V rocket that took Apollo astronauts to the moon. The Saturn V remains the most powerful rocket on the planet, releasing an impressive 7.6 million pounds of thrust at launch. The Space Shuttle debuted in 1981 as the world’s first reusable spacecraft, launching with two rocket boosters and gliding back to Earth. Crew Dragon is a free-flying spacecraft that gets its lift into space atop a rocket, similar to the Apollo missions. The 23-story tall SpaceX Falcon 9 rocket delivers nearly 2 million pounds of thrust.
The profile for Dragon differs from that of the Shuttle. With Falcon 9, during the staging from the first to the second stage, you experience a brief weightlessness followed by a G-force of around four plus Gs, whereas the Shuttle was limited to just 3 Gs. Putting humans atop any rocket involves risk and requires an escape plan. We conducted extensive engineering tests, including putting Dragon on top of Falcon and initiating the launch escape system to demonstrate that Dragon can safely carry the crew away from Falcon in an emergency.
Extensive testing and test flights covering every aspect of this mission have been ongoing for years. We have been to the International Space Station 21 times. This race for space will open a new chapter for the U.S. but comes with significant risks and challenges. Boeing’s Starliner narrowly avoided a disaster during a 2019 unmanned flight test when the spacecraft failed to reach the space station due to a software glitch but returned successfully to Earth. While SpaceX has achieved a major milestone, it has come at a considerable cost, overcoming many hurdles over 18 years of working toward this goal. When starting SpaceX, we estimated a 10% chance of reaching orbit, and it took us four attempts just to achieve orbit with Falcon 1. In the last two years, Falcon and Dragon have experienced several test failures, but all the learning has brought us to this point. We must not lose sight of the fact that this is a test flight, and we are taking safety very seriously.
