Virgin Galactic is due to send its first commercial flight into space on Thursday.
The spaceflight, dubbed the Galactic 01 by Sir Richard Branson’s private space tourism company, is set for take off at 4pm UK time.
But what is a commercial spaceflight? What will happen on board? And what does this mean for the future of space tourism?
What is a commercial spaceflight?
Put simply, it’s a flight into space that people pay for.
While Galactic 01 is being billed as Virgin Galactic’s first commercial flight, it won’t have tourists on board.
Instead, crew members will embark on a scientific research mission.
But when Galactic 02 takes off in August, it will carry paying customers.
What will happen on the flight?
Galactic 01 will carry three crew members from the Italian Air Force and National Research Council of Italy along with an astronaut instructor from Virgin Galactic.
The 90-minute flight will be suborbital, which means it will reach the edge of space without going into orbit.
The research crew will conduct 13 experiments examining biomedicine thermo-fluid dynamics and microgravity.
How will the launch work?
The spaceplane will be launched in mid-air from a carrier plane at an altitude of about 9.4 miles (15km).
Its rocket then fires the craft and its crew into sub-orbital space at least 50 miles (80km) above the Earth.
Passengers will experience five minutes of weightlessness.
How can I watch the launch?
Virgin Galactic will be streaming the launch and it will be available to view on the Sky News website and app.

How much are tourist tickets?
A ticket for a 90-minute trip to space will set you back $450,000 (£356,000).
According to Virgin Galactic, it’s a price people are willing to pay. “Demand is high”, the company’s website says, with several hundred customers already in line to fly.
What does this mean for the future of space tourism?
After the first tourist flight launches in August, Virgin Galactic flights are expected to take place every month.
The company is hoping to expand its flight schedule during the first years of operation.
Have tourists gone into space before?
American Dennis Tito was the first space tourist in 2001, paying Russia $20m (£16m) to fly to the International Space Station, where he spent a week.
Eight more space tourists travelled on Russian spaceflights between 2001 and 2009.
In 2022, three multimillionaire businessmen flew to the International Space Station on SpaceX‘s first private charter flight to the orbiting lab. They each paid $55m (£42m) for the rocket ride and accommodation.
Russia has been hosting visitors at the space station for decades. In 2021, a Russian movie crew was flown up, followed by a Japanese fashion tycoon and his assistant.
