It has developed Falcon 1 and Falcon 9 launch vehicles, which can be partially reused. Space Exploration Technologies has also developed a dragon series spacecraft to be launched into orbit by Falcon 9. Space Exploration Technologies mainly designs, tests and manufactures internal components, such as Merlin, Kestrel and Tianlong rocket engines.
In 2008, Space Exploration Technology Company won a formal contract with NASA. 20 12 10, SpaceX Dragon spacecraft delivered goods to the International Space Station, opening a new era of private space flight. By the end of 20 13 and 12, Space Exploration Technology Company had done eight experiments, and it could fall back to its original position after taking off at 1000 meters. However, the formal application of this technology will take time. Originally headquartered in Gondor, Else, California, it moved to Hawthorne in the same state.
20 18 on February 22nd, American space exploration technology company successfully launched a Falcon 9 rocket in vandenberg air force base, California, and put its two Internet experimental satellites, Microsat 2a and 2b, into orbit. On March 6th, a large satellite of Spanish satellite company Hispasat was put into orbit.
Put the dragon spacecraft into orbit on April 3. 2065438+On September 2, 2009, the Fengshen meteorological satellite of the European Space Agency collided with the "Star Chain 44" satellite of Space Exploration Technology Company. The European Space Agency (ESA) took an emergency orbit change operation on one of its satellites, thus avoiding a possible "space traffic accident".
At 3: 22 pm on May 30, 2020, NASA's Commercial Manned Aviation Program (CPP) was successfully launched for the first time. On August 2, the American "Dragon" spacecraft returned to Earth with two astronauts.

2065438+On September 2, 2009, the Fengshen meteorological satellite of the European Space Agency collided with the "Star Chain 44" satellite of Space Exploration Technology Company.
On September 3, 20 19, the European Space Agency issued a statement saying that about a week ago, the data of the US Air Force showed that on September 2, the European Space Agency's Fengshen meteorological satellite might collide with the "Star Chain 44" satellite. The Space Debris Office of the European Space Agency contacted the "Star Chain" team on August 28, and the team replied within one day that there was no plan to take action.
According to the European Space Agency, the probability of collision reaches one in ten thousand, which is the critical value to decide the action. In September 1 day, the collision probability increased to about one thousandth. On September 2, the European Space Agency decided that the American satellite would not change orbit according to the earlier communication records, so it issued an order to change the orbit of Fengshen satellite three times, thus avoiding the accident.
On September 3, 20 19, Space Exploration Technology Company said in a statement that when it contacted the European Space Agency on August 28, the collision risk was only one in 50,000, so no action was needed; Later, the US Air Force suggested that the risk of plane collision was greater than one in ten thousand, but the company's communication system failed, resulting in technicians not seeing the follow-up development emails.
Space Exploration Technology also stated in the statement that if the "Star Chain" technicians see the relevant communication content, they will definitely contact the European Space Agency to determine the best assistance plan or take evasive actions on their own.
