On February 10, the Us Academy of Engineering announced the list of additional academicians of the National Academy of Engineering in 2021, and SpaceX CEO Musk was officially selected.
Musk was selected for the following reasons:
Musk, Elon Reeve, founder, chief executive officer, and chief engineer, SpaceX, Hawthorne, Calif. For breakthroughs in the design, engineering, manufacturing, and operation of reusable launch vehicles and sustainable transportation and energy systems.
The U.S. Academy of Engineering recognized Musk's contributions to reusable launch vehicles, sustainable transportation, and energy systems. Reusable launch vehicles greatly reduce the cost of aerospace, making possible projects such as Starlink satellites, which require multiple rocket launches.
People can also often go to the International Space Station to replenish the International Space Station, the cost of air travel around the moon, moon landing and other air travel has dropped greatly, and more and more people can afford the cost of interstellar travel. Human exploration of Mars has become more convenient, and the process of modifying Mars can be greatly accelerated.

It is worth mentioning that Musk only has a bachelor's degree, but his achievements in physics and other aspects are actually not low. Musk first studied at Queen's University in Canada, then transferred to the University of Pennsylvania in the United States, where he received a double bachelor's degree in economics and physics. Musk also obtained the admission qualification for the Master's and Doctoral Degree in Materials science at Stanford University, but a few days after enrollment, Musk chose to drop out of school and start an Internet business.
In addition to being the CEO of SpaceX, Musk is also the chief technology officer of SpaceX, personally responsible for SpaceX's engineering and technical issues.
In addition, the selection criteria for academicians of the American Academy of Engineering are more inclined to the industry field, recognizing individuals who have made outstanding performance in the industry, and not only academic qualifications. By that standard, Musk does deserve to be selected.
