Space tourism is about to take off. Here’s how companies like Virgin Galactic, Blue Origin and SpaceX make sure visitors’ bodies can survive the journey.

Space tourism


  • The companies are preparing to take tourists to the edge of space in 2022.

  • Bidding for a seat aboard the Blue Origin spacecraft has reached a whopping $ 2.8 million.

  • As the trips get longer, the training regimes will ensure that people can handle the trip.

7;s Virgin Galactic and Jeff Bezos’ Blue Origin are gearing up to send tourists to the edge of space – and eventually after – in 2022. But for ordinary citizens, zero gravity and long flights can to cause chaos on their bodies.

Arriving in space is a naturally challenging experience, especially for the human body. That’s why companies hoping to sell travel take a page from NASA’s manual and run a rigorous training program for potential passengers to alleviate things like muscle atrophy and bone loss that studies show can happen when traveling. outside the atmosphere.

Virgin Galactic and Blue Origin set out to take tourists to the very ends of space. A flight aboard the Virgin Galactic spacecraft will provide you with a 6-minute space tour, and a flight aboard Blue Origin’s will give you an 11-minute tour that is not long enough for muscle atrophy or other effects to occur.

However, both companies require clients to take a training course before the expedition.

“There are a few days of training before the flight,” a spokesman for Blue Origin told Insider. “Some of the training includes training procedures for entering and exiting the capsule, mission simulation and techniques for learning how to move to zero g.”

The National Aerospace Training and Research Center “has already trained nearly 400 future Virgin Galactic passengers for their travels,” Glenn King, director of space flight training, told AFP. The training takes two days and includes morning training in the classroom and the use of a centrifuge to simulate gravitational forces, the telegraph service said.

Sirisha Bandla, vice president of state affairs for Virgin Galactic, said in an interview with Insider that customers would arrive a few days before their training flight.

“There’s talk at the same time about the safety system, how to buckle up and get out of your seat,” she said. “And to mentally prepare for the journey what will happen, so that when they are in the time of microgravity, they use this moment to look out the windows and enjoy the space flight.”

Virgin plans to send Kelly Gerardy, a researcher at the International Institute of Astronautical Sciences (IIAS), on a special research flight (with a date not yet set), the company said Thursday. It will experiment and test health technologies – such as zero-gravity syringes and bio-monitoring tools – while in space.

“I think it’s an ever-evolving landscape and a landscape of opportunity, especially for researchers and civilians,” Gerard told Insider. “I’m just looking at my three-year-old daughter, who was very excited today, and she just thinks that mothers go into space just like they do. And that’s wow, it’s going to be so great for her when she’s thirty as me, just growing up knowing that. “

Longer trips will be more complicated.

Later this year, Elon Musks’ SpaceX will board four civilians on its Dragon Crew spacecraft for space travel. The Inspiration4 mission will be “the first ever crew of non-professional astronauts to orbit the Earth for three days.”

So much time without gravity can have dire effects on the body, as astronauts have learned and trained in space flight over the past half century. According to NASA, astronauts need to train two hours a day to prepare their bodies for space travel, time spent there and travel back to Earth.

“They spend approximately 10 hours underwater for every hour they spend in space,” NASA said. “To maintain muscle strength while in space, astronauts practice core building activities before, during, and after their missions. Here on Earth, these activities may include swimming, running, weight training, or floor exercises.”

Artificial gravity can help. Blue Origin has visionary plans to house up to 1 trillion people in space in colonies, as Jeff Bezos pointed out in 2019. The settlements will exist in rotating cylinders designed to reproduce gravity, orbit the Earth and sustain human life.

His plan was backed by a new study published in the journal Nature in April that found that the effects of zero gravity on muscles could be mitigated by artificial gravity. The scientists measured these effects by sending two groups of mice into orbit on the International Space Station for 35 days to study the effects of Earth’s gravity on microgravity.

Perhaps unsurprisingly, their findings show that artificial gravity can “help stop the breakdown of muscle mass and alter the atrophy-related gene expressions that occur in space.”

Everything he teaches and explores means that travel will not be cheap

Blue Origin tickets currently cost up to $ 2.8 million per seat on the New Shepard spacecraft, and the price could rise even higher when a live auction is held on June 12.

Virgin Galactic, meanwhile, completed its third test flight to the edge of space on May 22, as the company prepares to take tourists into space as early as 2022. “About 600 customers have already paid $ 200,000 to $ 250,000 for space,” Insider reported. .

SpaceX did not say how much its first passenger, Yusaku Maezawa, paid to go on the company’s first lunar mission.

“He pays a lot of money that would help the ship and its booster,” Musk said in 2018. “Ultimately, he pays the average citizen to travel to other planets.”
