ClassX Video Lessons Youtube Channel Curiosity Stream How SpaceX and NASA Sent Astronauts to Space Again | Flight of the Dragon
SpaceX and NASA teamed up for an exciting mission to send astronauts to space using a commercial spacecraft. For the first time in history, NASA astronauts launched from American soil in a SpaceX Dragon spacecraft, marking a new era in space travel. The Falcon 9 rocket, carrying the Crew Dragon, took off from the Kennedy Space Center, the same place where Apollo missions to the Moon began 50 years ago.
It’s been nine years since American astronauts launched from the U.S. on American rockets. This mission was a big deal because it was the first time the Falcon 9 rocket carried humans into orbit. After spending over two months on the International Space Station (ISS), the crew returned safely to Earth, making history once again.
Since the space shuttle program ended, NASA has relied on Russian rockets to send astronauts to the ISS. This mission was a significant step in bringing space travel back to the U.S. SpaceX, led by Elon Musk, and Boeing have been competing to provide NASA with spacecraft to carry humans and cargo to space. SpaceX’s Crew Dragon has now proven its capability.
Before this mission, SpaceX conducted numerous tests to ensure safety. The Crew Dragon spacecraft is designed to be safe and reliable, featuring a modern cockpit with touchscreens. It’s a sleek, 21st-century spacecraft that can carry astronauts to the ISS and back without needing manual control, although astronauts have the option to take over if necessary.
The mission’s astronauts, Bob Behnken and Doug Hurley, are experienced space travelers. Doug Hurley was on the last space shuttle flight in 2011. Their journey on the Crew Dragon was not just about reaching the ISS but also testing new technologies, including their advanced space suits.
After their time on the ISS, Behnken and Hurley returned to Earth in the Crew Dragon. The spacecraft’s re-entry was dramatic, with a fiery descent through the atmosphere. Despite a hurricane in the Atlantic, the mission ended successfully with a splashdown in the Gulf of Mexico, marking the first splashdown since the Apollo missions.
This mission is just the beginning. The partnership between NASA and SpaceX opens doors for future missions to the Moon and Mars. The goal is to learn how to live and work on other planets, paving the way for humans to become a multiplanetary species.
When the last space shuttle left the ISS in 2011, the crew left behind a flag for the next American mission. With the success of the Crew Dragon, SpaceX and NASA have captured that flag, symbolizing a new chapter in space exploration. Congratulations to SpaceX and NASA for this incredible achievement!
Imagine you are an engineer at SpaceX. Design your own spacecraft that could carry astronauts to the International Space Station. Consider the features that would make it safe and efficient, like the Crew Dragon. Draw your design and label its parts, explaining how each part contributes to the mission’s success.
Create a timeline that highlights key events in space exploration, starting from the Apollo missions to the recent SpaceX Crew Dragon launch. Include important milestones such as the end of the space shuttle program and the first commercial spacecraft launch. Use images and brief descriptions to make your timeline engaging.
In groups, role-play a mission control scenario. Assign roles such as flight director, communication officer, and astronaut. Simulate a launch sequence, focusing on the communication and teamwork required to ensure a successful mission. Discuss the challenges faced by mission control during the Crew Dragon launch.
Research the biographies of astronauts Bob Behnken and Doug Hurley. Write a set of interview questions you would ask them about their experiences on the Crew Dragon mission. Pair up with a classmate and take turns role-playing as the astronaut and the interviewer, discussing their journey and the new technologies they tested.
Participate in a class debate about the future of space travel. One side will argue for the importance of government-led missions, while the other will support commercial space travel led by companies like SpaceX. Use evidence from the article and additional research to support your arguments, and discuss the potential benefits and challenges of each approach.

[Music] SpaceX Dragon, we’re go for launch. Let’s light this candle. 5, 4, 3, 2, 1, zero ignition, liftoff for the Falcon 9 and Crew Dragon. Go NASA, go SpaceX! America has launched for the first time in history. NASA astronauts have launched from America in a commercial spacecraft to the International Space Station.
T plus 30 seconds into this historic mission, flying crew on board Dragon and Falcon 9. The vehicle is supersonic. It’s been 9 years since we’ve launched American astronauts on American rockets from American soil. This is the first Falcon 9 to carry humans to orbit. What a great day for the United States of America!
One meter to go, we have docking. After more than two months aboard the International Space Station, please confirm your visors are down and that you are ready for undock and departure. The crew safely returned to Earth in another historic first. We’re looking at Dragon streaking across the sky on its re-entry through the Earth’s atmosphere, and then those parachutes are going to kick in. This is something the whole world can take pleasure in and can really look at as an achievement of humanity.
Splashdown! No matter where you are on planet Earth, this is a good thing, and I hope it brightens your day. We have visual confirmation for splashdown. 10, 9, 8, 7, we have a go for remaining start. 4, 3, 2, 1, booster ignition.
Since the space shuttle was retired nearly a decade ago, it’s been a race among several aerospace companies to be chosen as NASA’s solution to carry humans and cargo to space. Boeing and SpaceX have emerged as key suppliers, and now Elon Musk’s SpaceX has made history with its revolutionary Crew Dragon spaceship.
I’m really quite overcome with emotion on this day. It’s been 18 years working towards this goal, so it’s hard to believe that it’s happened. On May 30th, a Falcon 9 rocket with a Dragon on top lifted off from the Kennedy Space Center, from the same launch pad that sent the Apollo astronauts to the Moon 50 years ago.
Without a space shuttle alternative, the United States had been dependent upon Russia to maintain an American presence on the International Space Station for the last 9 years, purchasing rides on Russian Soyuz rockets, with costs rising significantly to nearly $4 billion. The International Space Station is a critical capability for the United States, and having access to it is also critical.
There’s a lot of significance to bringing these missions back to American soil as an alternative to the Soyuz solution. As an American, I’m proud of what we’ll be able to accomplish and fly again on an American rocket from American soil. It’s remarkable to think that the last time a crewed launch vehicle departed from the United States was 2011.
This mission demonstrates a remarkable role reversal for how America goes to space. This time, we’re doing it differently than we’ve ever done it before. NASA is not going to purchase, own, and operate the hardware; in fact, we’re going to be a customer with both Dragon and Starliner programs in the works. NASA has redundancy, which they depend on in all aspects of spaceflight.
Once this test mission is complete, Dragon will be cleared to fly official crew missions, and Starliner will continue development of their program. SpaceX has been hauling cargo on Dragon to the ISS since 2012, successfully completing the first test run of the all-new Crew Dragon to the ISS in 2019.
Last year, we had our demonstration mission, which was the Crew Dragon without any crew on board going to the space station. Demo 1 marked the first time in history a spacecraft docked autonomously without help from the mothership. 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, most importantly that Dragon can safely transport passengers.
This historic flight used a brand new spacecraft, similar to 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 pieces of the mission, following a standard set by the Saturn V rocket that took Apollo astronauts to the Moon.
The Space Shuttle debuted in 1981 as the world’s first reusable spacecraft. Crew Dragon is a free-flying spacecraft that gets its lift into space atop a rocket. The 23-story tall SpaceX original delivers nearly 2 million pounds of thrust.
Putting humans atop any rocket requires risk and an escape plan. We demonstrated that Dragon is capable of carrying the crew away from Falcon in the event of an emergency. Extensive testing and test flights covering every aspect of this mission have been going on 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 requires great risk and has not been without its serious challenges. Boeing’s Starliner narrowly avoided disaster during a 2019 unmanned flight test due to a software glitch but returned successfully to Earth.
While SpaceX has completed a major milestone, it’s come at a big price, overcoming many hurdles. When starting SpaceX, we maybe had a 10% chance of reaching orbit. It took us four attempts just to get to orbit with Falcon 1. In the last two years, Falcon and Dragon have experienced several test failures, but all the learning has brought them to this point.
We should not lose sight of the fact that this is a test flight that we’re taking very seriously from a safety perspective. While the Space Shuttle was hardware-heavy, Dragon is light and sleek. The two big differences are that the Shuttle was a hauling truck for big payloads, while Dragon is a smaller capsule with a smaller crew and not a lot of cargo.
Dragon features a modern cockpit with large touchscreens, designed for humans by humans. Crew Dragon is a 21st-century spacecraft, safe and reliable, and also looks amazing. It can carry the crew safely to the station and bring them home without direct intervention, but we want to ensure the crew has all the tools possible in case they need to manually pilot Dragon’s flight.
This mission marks a new era in human spaceflight. The two astronauts on board, Bob Behnken and Doug Hurley, are veterans who flew on NASA’s Space Shuttle. Hurley was on the very last shuttle flight to the space station in 2011.
The Dragon mission is all about technology breakthroughs, right down to the astronauts’ space suits. The suits are one-piece, providing air, oxygen supply, and maintaining pressure and temperature. They also have an integrated communication system. Both Dragon and the Falcon 9 rocket are designed to be reused, with Dragon designed for reflight up to five times.
After launch, the rocket’s first stage made an extraordinary return to Earth, landing on an ocean platform. Falcon 9’s second stage delivered Crew Dragon to orbit after a 12-minute ride, where they promptly phoned home.
The crew spent a day in Earth orbit, flying Dragon manually to test their control capability and preparing for their historic docking with the ISS. Day two, Dragon performed a flawless precision docking with the station autonomously.
Bob and Doug welcomed the crew aboard the International Space Station, marking the first time since the retirement of the Space Shuttle that astronauts completed a historic ride to the ISS. The Demo 2 mission had been historic in a very different way due to the ongoing global pandemic, with NASA asking that no spectators attend the launch to keep everyone safe.
Benken and Hurley spent two months aboard the ISS, assisting the international crew with numerous science experiments, performing maintenance, and monitoring the health of their Dragon spacecraft.
After a careful inspection of their capsule, Hurley and Behnken bid farewell to the space station crew and undocked from the ISS. After a 19-hour journey, Crew Dragon performed its final deorbit burn to drop out of Earth orbit, bracing for a dramatic re-entry.
The spacecraft is engulfed in a plasma bubble of hot gases during re-entry, creating a communications blackout that could last up to 6 minutes. One final exchange between mission control and Crew Dragon confirmed their status.
A brewing hurricane in the Atlantic caused NASA to make a last-minute change to an alternate splashdown site in the Gulf of Mexico. The parachutes deployed to slow Crew Dragon for its splashdown.
There we have confirmation of splashdown! Dragon has returned to planet Earth. The splashdown in the Atlantic Ocean is historic, marking the first time since Apollo that SpaceX and NASA teams welcome back a spacecraft.
This successful NASA SpaceX public-private partnership opens the door to Moon and Mars exploration. Today we’re flying into low Earth orbit, and in a few short years, we want to be flying to the Moon sustainably. We’re going to learn how to live and work on another world for long periods of time and take that knowledge to Mars.
This is hopefully the first step on a journey towards civilization on Mars, becoming multiplanetary. The pandemic has connected us all in a way that causes us to reconsider our connection and how important it is for us to work together going forward.
When the STS-135 crew departed the ISS on the last shuttle flight in 2011, they left a flag for the next American mission. This flag represents not just a symbol of national pride but also a goal.
Now the Dragon and its crew have captured the flag and made history. Congratulations, SpaceX!
