Jeff bezo, the founder of blue origin, also wore a cowboy hat after the spacecraft landed, while Richard Branson, the boss of virgin galaxy, said the blue jumpsuit he wore was "sexy" < p > in the view of some top safety experts in the field of space travel around the world, another point is particularly striking: neither company has equipped passengers on the spacecraft with pressure suits to protect them from the potential impact of rapid decompression outside the earth's atmosphere < p > NASA and other organizations have learned painful lessons from fatal accidents, so astronauts are generally required to wear pressurized spacesuits when entering space, but these standards are not applicable to space tourism companies competing to commercialize space. The United States Congress also exempted such enterprises from the safety supervision requirements for crew members < p > "the fact is that when you enter space, you need to wear the right clothes instead of beautiful clothes," said Tommaso sgobba, a former official of the European Space Agency and executive director of the International Association for the promotion of space security < p > the successful launch of two private spaceships last month promoted the development of the U.S. commercial space industry. Supporters say that the exemption rule is a key factor in rapid innovation, and this model should be promoted < p > earlier this year, Mike Moses, President of Virgin Galactic in charge of space mission and safety, told lawmakers at a hearing that the industry "is still in its infancy. In order to support more people in space flight, it needs more time to have an informed discussion on what regulatory framework to adopt in the future." < p > but sgoba and others said regulators should impose more restrictions on these enterprises. After all, rocket launch is a notorious danger. Rockets are like giant bombs. History has proved that they are difficult to achieve high reliability, and the harsh space environment leaves little room for fault tolerance < p > George nield, an industry consultant, said that since the early 1960s, the United States has conducted 379 manned space flights, four of which ended in fatal accidents. In the 10 years before 2018, nild was the head of the office responsible for commercial launch of the Federal Aviation Administration (FAA). This statistic means that manned space flight has a probability of failure of about 1% < p > FAA will review various launch applications to ensure that the public on the ground or on passing aircraft will not be injured in the event of an accident. As part of this work, the FAA will also review the reliability of rockets and spacecraft, but the United States Congress prohibits the agency from formulating any rules to protect crew members < p > Virgin Galactic and blue origin did not respond to requests for comment. The regulation suspending the safety supervision of crew members by the Federal Aviation Administration began in 2004. Driven by millions of dollars of lobbying activities, the effectiveness of the regulation will continue until at least 2023 Sgoba, nierd and others said that the law should no longer work. More importantly, they fear that a disaster could silence the booming commercial space industry for years < p > "I think it's time to update our regulatory framework for manned spaceflight," nield said < p > in the past, US Congressmen never hesitated to extend the space safety regulatory ban. After all, the industry has strong allies in Congress. But now some people are calling for change“ With the rise of space tourism, I don't think we should tie the hands and feet of the agencies responsible for safety supervision, "said Peter DeFazio, a democratic representative of Oregon and chairman of the house transportation and Infrastructure Committee < p > commercial space companies insist that the so-called "learning period" is crucial to the rapid expansion of business, and the ban on space safety supervision should be extended. They said that enterprises only need to follow broad safety measures, and too detailed and strict rules and regulations will hinder innovation < p > Karina drees, President of the commercial spaceflight Federation, said: "if all spacecraft are strictly regulated in the same way, it will fundamentally limit the design characteristics of these spacecraft." Members of this organization include blue origin, virgin galaxy and dozens of other companies < p > manned space disaster < / P > < p > in addition to blue origin and virgin galaxy, SpaceX has used the manned dragon flying ship to send NASA astronauts to the international space station. Billionaire Jared Isaacman bought seats on the dragon flying ship from SpaceX and will launch as early as September 15 this year. In addition, axiom space, a space tourism company in Texas, has signed a contract with SpaceX to send paying passengers into space as early as January next year. Boeing and Sierra Nevada are also developing manned spacecraft < p > the recent technological achievements of commercial space launch are undeniable, but the long-term safety record of space flight is alarming. The two deadliest accidents occurred on the space shuttle. The space shuttle carried out 135 missions and 14 people died before and after < p > on October 31, 2014, a serious accident occurred during a test flight of the Virgin Galactic VSS unity spacecraft. When the spacecraft accelerated, a test pilot accidentally turned the switch to start a device for slowing down and stabilizing the spacecraft during descent, resulting in the disintegration of the spacecraft < p > the National Transportation Safety Board (NTSB), which is responsible for investigating civil space accidents, found that the company responsible for building the spacecraft at that time had many security vulnerabilities. NTSB said that the designers did not anticipate the possibility of human operation errors < p > Secret of design < / P > < p > Branson said that the accident investigation made his company "safer and better", and Virgin Group took over the manufacture of the spacecraft. Drees of the commercial aerospace Federation said the industry had "made an immediate and comprehensive response" to NTSB's recommendations < p > sgoba said that because there is no unified safety standard and private companies tend to keep secrets when designing spacecraft, it is difficult to know what protection measures the spacecraft has < p > he said that in recent manned space launches, passengers did not wear pressurized spacesuits, which seems to be the practice followed by commercial space companies when designing spacecraft. NASA and other agencies require astronauts ?
