Space Tourism: From Suborbital to Orbital

SpaceTRC / Space Age / Space tourism

From four minutes of weightlessness to a polar orbit.

“Space tourism” covers two very different experiences. A suborbital flight takes you to about 100 km and brings you back within minutes. An orbital flight circles Earth for days. The difference is not altitude but speed and energy.

01 / The key difference

Reaching space is easy; staying there is hard

To climb straight up to 100 km and fall back you need about 1.4 km/s. To stay in orbit at that height you need about 7.8 km/s sideways. Because energy grows with the square of speed, the gap exceeds a factor of thirty. That is why New Shepard flies on an 18-metre rocket while Crew Dragon rides a 70-metre Falcon 9.

Suborbital

Up, then back down

The vehicle traces an arc like a ball thrown upwards. After engine cutoff, passengers float for 3–4 minutes and see the curve of Earth. A New Shepard flight lasts about 10–11 minutes in total.

Orbital

Falling around the planet

The vehicle moves fast enough to circle Earth about every 90 minutes. It is always falling but keeps missing the ground. Passengers stay weightless for days and see 16 sunrises a day.

Energy calculator: suborbital versus orbital

Change the altitude. The calculator compares, per kilogram, the energy needed to climb to that height and stop with the energy needed to circle at that height.

Prices are mostly undisclosed. Blue Origin asked applicants for a 150,000-dollar deposit; reported prices for Axiom station missions run to tens of millions of dollars per seat.

Why New Shepard stopped

Blue Origin suspended suborbital tourism for at least two years and redirected resources to its Blue Moon lander for NASA’s Artemis programme. Before the pause, the programme had flown 38 times and carried 98 people to space.

Virgin Galactic’s pause

After its last VSS Unity flight, Galactic 07, the company paused flights to move to Delta-class ships. It says they can fly up to twice a week with a lifetime of over 500 missions.

2021 → today

Private orbital missions

Inspiration4, Polaris Dawn and Fram2 made orbital tourism possible without docking at a station, each chasing a “first”: first civilian crew, first commercial spacewalk, first polar orbit.

05 / Türkiye

Turkish astronauts: two flights, two paths

Türkiye’s two astronauts flew in 2024 on two very different commercial flights: one spent weeks in orbit, the other made a minutes-long suborbital research flight.

Orbital · Ax-3

Alper Gezeravcı

Launched on 18 January 2024 aboard a Falcon 9 and Crew Dragon, he ran experiments prepared by Turkish scientists on the International Space Station. The crew splashed down off Florida on 9 February 2024.

Suborbital · Galactic 07

Tuva Cihangir Atasever

He flew on 8 June 2024 from Spaceport America in New Mexico aboard Virgin Galactic’s VSS Unity, reached about 90 km and ran seven scientific experiments during roughly three minutes of free fall.

The next big step is uncrewed: TÜBİTAK UZAY’s AYAP-1 lunar orbiter is planned to launch on a Falcon 9 in 2027.

06 / The future

Health, safety and what comes next

What the body goes through

Passengers feel about 3–5 g at launch, and briefly more on a suborbital descent. Space sickness is common in the first days in orbit; long missions bring bone and muscle loss, radiation exposure and fluid shifts.

Who licenses it?

In the US, the Federal Aviation Administration (FAA) licenses commercial crewed launches. Passengers sign an “informed consent” acknowledging that the government has not certified the vehicle as safe.

What’s next

Axiom’s fifth station mission is planned for January 2027 at the earliest, and Virgin Galactic expects Delta-class passenger flights in 2027. Several companies are building commercial space stations for the post-ISS era.
