[ 随着太空舱咆哮着进入佛罗里达的天空，太空舱与猎鹰9号火箭分离，开始向预定轨道移动，并将最终达到距离地面357英里（575公里）的高度绕地飞行，在这一高度，龙飞船将以每小时17000英里（27360公里/小时）的速度，每90分钟环绕地球一周，这一速度大约是音速的22倍。 ]
At 8 pm Eastern Time on September 15, SpaceX’s first commercial space travel mission set sail on time. Four non-professional astronauts took SpaceX’s “Dragon Spacecraft” to orbit the earth without the accompaniment of professionals. They It will orbit the earth for three days.
The launch pad of NASA’s Kennedy Space Center in Florida was illuminated by a spotlight against the night sky. Four hours before liftoff, in front of SpaceX’s huge rocket backdrop, four space travelers waved to their families and SpaceX employees. Wearing slick white flight suits full of science fiction, they walked to the space hatch amidst the cheers of the audience.
Prior to this, they had undergone six months of flight training, including practice in SpaceX’s capsule simulator.
As the space capsule roared into the Florida sky, the space capsule separated from the Falcon 9 rocket and began to move toward a predetermined orbit. It will eventually reach an altitude of 357 miles (575 kilometers) above the ground orbiting the ground, which is higher than the international level. The space station must be 100 miles (160 kilometers) higher. At this altitude, the Dragon spacecraft will circle the earth every 90 minutes at a speed of 17,000 miles per hour (27,360 km/h), which is approximately 22 times the speed of sound.
They are expected to land on the Florida coast this Saturday. If there are factors such as weather influences, the return time will be delayed.
In the next three days of the flight, there will be no shower facilities and no special sleeping space. The four passengers can only stay in their own seats and share a special zero-gravity toilet near the top of the capsule, but there will be plenty of food during the trip. And supplies, can be used for one week.
This mission, called Inspiration 4, is SpaceX’s first all-civilian space travel, but the price of travel is not civilian-oriented. Time magazine estimates that the total value of the “ship tickets” for four passengers will reach 200 million U.S. dollars. This is comparable to the cost of SpaceX sending NASA astronauts to space.
It was not SpaceX founder Musk who led the mission, but 38-year-old American e-commerce tycoon Jared Isaacman (Jared Isaacman), who founded a payment company when he was a teenager. Take the first pot of gold. Isaacman also became the third billionaire to fly into space after Richard Branson of Virgin Galactic and Jeff Bezos of Blue Origin.
The other three travelers are 51-year-old geoscientist Sian Proctor, 29-year-old bone cancer recoverer, Hayley Arceneaux, and 42-year-old aerospace data engineer Chris Sembroski (Chris Sembroski) .
This summer, SpaceX rivals Virgin Galactic and Blue Origin have launched their own private astronaut services, but these missions are more like sightseeing, returning only after a few minutes in suborbit. SpaceX also became the first company to send civilian space passengers to Earth orbit.
Previously, due to concerns about radiation exposure and other unknown risks, SpaceX was initially reluctant to carry out the mission, but agreed to the mission after a safety review. “Now I just hope to fly higher.” Isaacman said before the flight, “If we are going to the moon again, to Mars or farther, then we must get out of our comfort zone and move in that direction. Take the next step.”
In 1986, after the “Challenger” carrying the New Jersey school teacher Christa McAuliffe was killed, NASA has been opposed to allowing non-astronauts to participate in space missions, but a group of wealthy thrill seekers still paid privately Participate in international space missions. At the beginning of this century, US investment management billionaire Dennis Tito (Dennis Tito) stayed on the International Space Station for eight days and became the first person to enter space travel by way of self-financing. Since then, six people have booked the itinerary for the Russian Soyuz spacecraft with professional astronauts in the same way.
Today, NASA has also become a supporter. Although NASA did not participate in SpaceX’s launch mission, its staff cheered SpaceX’s first civilian launch. “The more people involved in space travel, the better, whether it is a private or government project.” NASA astronaut Shane Kimbru said. Kimburo has been working on the International Space Station for nearly 6 months and is about to return.
According to reports, SpaceX’s next private trip will take place early next year, when a retired Russian astronaut from NASA will escort three civilians to the space station for a week-long visit. The civilian population includes an actor, a film director and a wealthy Japanese businessman.
SpaceX’s mission will once again ignite the enthusiasm of civilian space travel, and also mark the beginning of a new era of space travel. In this era, as long as you have an adventurous spirit, you have the hope to undertake the mission of space exploration. However, since the current cost of space travel is still high, there is still a long way to go before everyone can fly into space. SpaceX’s journey is just the beginning. Return to Sohu to see more
