In 2001, a 30-year-old young man named Elon Musk, co-founder of PayPal, was trying to get the public’s attention back for space exploration after the space race was over.
00:15 - Mars Oasis was his idea at the time, an ambitious project to bring plants to Mars.
00:21 - He planned to use cheap Russian rockets to do this.
00:24 - He immediately flew to Moscow to look for one.
00:27 - But no one wanted to sell. He returned to America with empty hands On the return trip, An idea came to mind, Why don’t he, start a company, then design and manufacture his own rockets? He embarked on building his company recruiting personnel, invited rocket experts for research.
00:44 - A year later, SpaceX was born. On May 6, 2002, SpaceX was founded with $100 million worth of self-investment from Elon, plus an additional $34. 1 million from two funding rounds.
01:13 - SpaceX was ready to produce its first rockets, starting with Falcon 1.
01:17 - On 24 March 2006, the first Falcon 1 was launched from Omelek Island, in the Marshall Islands carrying the FalconSAT-2 satellite after two delays.
01:25 - But, after only 26 seconds, the rocket lost contorl and crashed into a dead reef 77 meters away from the launch pad.
01:31 - A year later, SpaceX tested the rocket for the second time, the second test was better when the first stage was separated.
01:37 - However, engine malfunction occurred in T+ 5 minutes leading to a complete shutdown 2 minutes later.
01:42 - The missile got to an altitude of 289 km but does not have enough horizontal speed to complete an orbit.
01:48 - After another failure, on September 28, 2008, the Falcon 1 rocket carrying the DemoSat satellite orbited successfully, becoming the first private rocket to orbit the Earth.
01:59 - Although it was not until 6 years after its founding that SpaceX successfully launched its first rocket, but after only its first test, NASA took notice, and selected the company as one of the participants of the Commerical Orbital Transportation Service (COTS) a NASA program that allows private companies to send supplies to the ISS.
02:18 - After the fourth successful launch, NASA officially signed a contract with SpaceX worth $1. 6 billion to supply the station.
02:25 - That same year, the company revealed the Falcon 9 rocket.
02:35 - After the integration of the Falcon 9 rocket, SpaceX immediately got to work…
02:40 -… by further testing the Falcon 1. The fifth launch of the rocket in mid-2009, carrying Malaysian satellites RazakSat made it the first company to put a commercial satellite into orbit A year later, at launch pad number 40 in Cape Canaveral, Florida.
02:55 - The Falcon 9 rocket and the Dragon Spacecraft Qualification Unit, simultaneously completed their missions.
03:01 - The Falcon 9 was officially put into service, and was quickly put to test by SpaceX for the first mission of NASA’s COTS program.
03:08 - Mission succeeded and SpaceX becomes the first private company to launch, orbit, and recover a spaceship.
03:15 - In the next launches, the Dragon became the first private spacecraft to supply food to the Station.
03:22 - From that point onwards, SpaceX and the Falcon 9, became trusted partners of NASA and other companies to put payload into orbit.
03:30 - But Elon Musk wanted to put SpaceX into the history book.
03:33 - In September 2011, the company announced plans to build reusable rockets.
03:38 - Making reusable rockets is not a new idea in the space industry.
03:41 - NASA’s space shuttle could theoretically be reused, but its financial efficiency was not good.
03:47 - SpaceX wanted to change that. The company started development on some prototypes like the Grasshopper and the F9R Dev 1.
03:53 - A year later, the company decided to test its landing system on the Falcon 9 after each mission Failures after failures, but SpaceX did not give up On 22 December 2015, after the 20th launch of the Falcon 9 rocket, the first stage of the missile separated, the engine reignited…
04:08 - and… The first stage of the rocket successfully landed in Landing Zone 1, marking a historic moment for the space industry and the company.
04:28 - A year later, the company succeeded in landing a rocket on a floating platform in the Atlantic Ocean.
04:41 - In 2014, the company and Boeing were selected by NASA in Commercial Crew Program to put astronauts on the International space station SpaceX had one more achievement to conquer to become the first private company to put humans into space After receiving the contract, the companies embarked on designing the second generation of the Dragon spacecraft capable of transporting humans.
05:00 - The Dragon 2 is partially reusable, It can directly dock to the ISS.
05:05 - and has a maximum capacity of seven astronauts.
05:07 - The ship is equipped with the powerful Draco and SuperDraco engine system, accompanied by an autopilot system, fins and radiators for atmospheric reentry once the mission was over.
05:16 - The design is completed, testing begins. On May 6, 2015 SpaceX had a ground-based test of the ship’s abort system.
05:24 - A system that will help the crew to escape the rocket and land safely in the event of an incident.
05:28 - The test was a success. On 24 November of the same year, the company continued to test the ship’s abort engine.
05:34 - This time, the goal is to have the ship hover in the air for 5 seconds.
05:37 - The test was successful again Progress was going very well, the company planned to launch a manned mission in July 2019 March 2, 2019, 4 months, before the manned mission, SpaceX launched an unmanned mission to the ISS named Demo-1 The mission was a success.
05:53 - The Dragon splashed down successfully after 6 days in space Everything was ready for the first launch of American astronauts on American soils since the cancellation of the Space Shuttle program in 2011.
06:05 - On April 20, 2019, during an engine test, the Dragon suddenly exploded.
06:10 - The explosion caused NASA and SpaceX to delay the manned mission to May 2020 On January 19, 2020, SpaceX conducted a test launch of the Dragon on its Falcon 9.
06:20 - Everything went well, but about 90 seconds after launch, the rocket’s engine suddenly turned off, a few seconds later, a fireball appeared the Falcon 9 disappeared.
06:29 - wait why is everyone clapping oh. got it.
06:33 - SpaceX has successfully tested the ship’s abort system.
06:36 - completing the final stages of testing before the launch of two American astronauts in mid-2020.
06:42 - And that day finally arrived. May 30, 2020, Two astronauts, Douglas Hurley and Robert Behnken, boarded the Endeavor on the Falcon 9 ready for the Demo-2 mission.
07:00 - A weather incident delayed the previous launch attempt for two days but today was different, An evening with few clouds, sufficient for a rocket launch.
07:08 - The countdown begins, 5 4 3 2 1 The rocket shot up into the air, overcoming the influence of gravity 2 minutes 40 seconds after launch, the main engine separated.
07:31 - 9 minutes 36 seconds, the first stage successfully landed.
07:34 - Endeavor continues on its way to the ISS. 22 hours later, two astronauts ‘hovered’ into the space station.
07:41 - But there was still one last dangerous phase of the mission, the return to Earth 62 days later.
07:47 - The return is more dangerous than the launch.
07:50 - We all know about images of flaming meteorites when they enter into Earth’s atmosphere, right? Spacecrafts that return to Earth also face this extremely dangerous condition.
07:57 - Endeavor touched the first atmospheric layer at 6:11 p. m. on August 2.
08:02 - During the atmospheric reentry, the two astronauts suffered up to 4G of G-Force 33 minutes later, the parachutes were deployed.
08:09 - At 18:48, Endeavor landed safely on the Gulf of Mexico.
08:12 - The mission ends. Since 2001, Elon Musk has been cherishing his Mars dream.
08:26 - In 2007, he announced his intention to bring the first humans to and colonize on the Red Planet Elon aims to have the first humans on Mars in the mid-2020s.
08:35 - In 2012, the company announced plans for a new rocket model called the Mars Colonial Transporter, known today as the Starship Starship is a super-heavy rocket capable of complete reusability, and can transport humans from Earth to Mars, and vice versa.
08:50 - The rocket consists of 2 stages, The first stage is called the Super Heavy, it has 28 Raptor engines that deliver rockets to orbit.
08:56 - The second stage is called Starship, it has 6 Raptor engines capable of bringing the rocket to interplanetary orbit, capable of entering atmospheres safely, and capable of landing vertically.
09:05 - Testing of the Starship is underway, with the latest test of the SN8 prototype flying to 12. 5 km.
09:12 - The Starship is expected to have a complete launch in 2021.
09:17 - In addition to the Starship, SpaceX also has many other ambitious projects, such as the 42,000 satellite Internet constellation project called Starlink that helps bring the Internet to the entire world.
09:26 - Project #dearMoon which will take Japanese billionaire Yusaku Maezawa around the Moon or projects that support NASA in the Artemis program to bring the next humans to the Moon in the next few years From the dream of getting the public to be more excited about space exploration, Elon Musk founded and helped SpaceX to become arguably the most famous company in the rocket and space industry With so many extraordinary achievements in such a short time, it seems that the future of human space exploration is very open.
