New spacecraft Orion/ESM surprisingly reuseable

There is a new contender in the human space race. The NASA/ESA-built Orion ESM spacecraft is the most versatile spaceship humans have ever built.

After the US space shuttle was cancelled in 2011, the russian Roscosmos was the only solution to get humans up into orbit. SpaceX tested the Dragon Crew Capsule in 2019 and started offering astronaut seats to space in the Crew Capsule on top of its Falcon 9 Rocket in 2020.

Jeff Bezos’ Blue Origin offer flights just below the orbital range, same as Richard Branson’s Virgin Galactic. Both are in the planning and development phase to offer flights above the Karman line and into actual orbital space, with Blue Origin probably being the closest to succeed.

During the years the Roscosmos was the only option the russians charged around 50 to 60 million USD per seat. No wonder then SpaceX set its price-per-passenger at exactly 55 million USD. And to date, there are no other private options to get to orbit anywhere in the world.

Millions of dollars per launch

There is obviously a lot of money to be made in space. SpaceX is not the only company that have realized this fact. Over the coming years there will be a flurry of announcements from new and hopeful contenders in the orbital launch race.

The NASA-supported Orion is not built to hit rock-bottom prices for astronauts, rather it’s a new science and exploration platform. The water and air filtration systems onboard can keep astronauts alive for months.

The characteristics of the Orion spacecraft are such that it lends itself to the private space industry, as the module is reusable. After a completed mission and release of the crew compartment the ESM (the European Service Module) ship can continue to function in space, remotely-controlled.

There is really no point in comparing the cost per seat in the Orion Spacecraft, it’s still in the billions-per-launch. The objectives are different. The goal of Oriaon is not to compete with Roscosmos on price-per-seat to orbit. Orion is a more complicated and versatile craft that can perform a multitude of scientic tasks, as well as travelling to many different destinations in the solar system. You could send humans to the asteroid belt in an Orion, and that will probably happen in the coming years.

Even more reusable providers are coming

When companies like Pulsar Fusion reach the commercial stage and can provide fusion propulsion in space the next space race will take off. The question is: who will be able to provide a cheaper human orbital launch option? Fusion propulsion is not going to work back down on the Earth’s surface or in the atmosphere, only in space. So there will still be a need for orbital launch providers for a long time to come.

As of yet, there are no credible technologies being developed for launching off the surface. Chemical rockets are still the only way humans can leave Earth. Other technologies like ion engines, fusion or thermal-nuclear propulsion, or laser-based propulsion, are only effective in the vacuum of space and/or in micro/zero gravity.

There are however several ongoing developments from new contenders attempting to reach orbit with reusable rockets. US-based Firefly is one, Radian Aerospace mentioned above another. SpaceX is of course also a contender if it can get the giant upper stage that is the Starship to take off and land safely.

But wait, there’s more… there are companies in Germany, China, India, Pakistan, Norway and the UK, to name a few, that are all trying to achieve reusable spaceflight. The providers all have timelines with 2026 and 2027 launches planned, so stay tuned to this space. We’ll update on all human-rated orbital launch options as they become available.
