NASA announced today that it approved extensions of eight very successful planetary missions. Their targets range from Mars and nearby asteroids to the most distant reaches of the solar system. Each of the missions went through an evaluation process within NASA. Science panels examined the scientific output of each mission as well as its potential future accomplishments.

OSIRIS-APEX Continues its Asteroid Mission

Asteroids remain high on the planetary mission study list. The Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission is about to deliver some much-anticipated samples from asteroid Bennu. The mission grabbed these bits of the asteroid in 2020.

With the new extension, the mission is changing its name slightly to OSIRIS-APophis EXplorer (OSIRIS-APEX). The name indicates the new exploration goals for the spacecraft which it will fulfill during an encounter with asteroid Apophis in 2029.

Apophis is an S-type asteroid, meaning it’s a stony (siliceous) composition. It’s on an orbit that will bring it to within 20,000 miles (32,000 kilometers) of Earth in 2029. That will give the spacecraft a good “close-up” encounter as it enters orbit around Apophis. If all goes well, the spacecraft’s thrusters will loosen up some dust and small rocks on and below Apophis’ surface and return data for further study.

Extended Planetary Missions at Mars

Several spacecraft currently studying Mars got life extensions, too. They are:

• the InSight mission, the only active seismic station on the Red Planet
• the Mars Science Laboratory (with the Curiosity rover);
• the MAVEN mission (currently studying the Martian atmosphere);
• Mars Odyssey (also doing climate monitoring), which will extend its attention to the thermal studies of rocks and ice beneath the Martian surface;
• and the Mars Reconnaissance Orbiter. It has been extended six times now and continues to provide insights into the Mars’ surface, geology, atmosphere, climate, and surface ices.

The extension of these missions continues to provide long-term data about Mars, which is necessary for future explorations by both robotic probes and humans.

Extending a Lunar Planetary Mapping Mission

The Lunar Reconnaissance Orbiter has been doing a wonderful job giving us long-term studies of lunar geology and mapping the Moon’s surface. It got an extension to study new regions, including the permanently shadowed areas where water ice may exist in some abundance. The Moon is NASA’s next target for renewed human exploration. So, it’s important to get as much information about resources as possible.

A Planetary Mission Explores Distant Reaches

Finally, the New Horizons mission, which successfully explored Pluto and the Kuiper Belt Object called Arrokoth. It’s in its second extended mission, and now has a third extension. Its ultimate job is to explore the distant solar system out to a distance of at least 63 astronomical units. It can do different kinds of observations of additional bodies it might fly by. It will also monitor the influence of the Sun in these distant parts of the solar system.

Going the Limit on Planetary Missions

Each of these spacecraft will, of course, eventually run out of fuel. Or, they will lose components during their missions, Still, NASA weighed the consequences of those future events. Each mission has its limits, of course. But, the extensions they received are good-faith moves. They make the most of the assets we have in near-Earth space, on the Moon, Mars, and out in the Kuiper Belt.

These eight are part of a fleet of 14 spacecraft NASA is operating. In the future, we can expect to see possibly a dozen more missions to the planets, operated by NASA and its international partners in planetary exploration.

So, apropos of the launch of four Axiom Space astronauts to the International Space station, I did a short interview with a writer in Singapore about the future of space commercialization. They asked me what I thought two big directions for commercialization would be. Now there are many directions space commerce can and will take. I chose two that have piqued my interest: space tourism and asteroid resource mining. Space tourism is more likely to happen sooner, mostly because the infrastructure for mining is still to be built. And, of course, the market needs to be defined and built. There ARE companies thinking about this, so it will happen. It just remains to be seen WHEN it will happen.

Space Commercialization: People Have Opinions

I noticed that after the Axiom launch, the discussion about commercializing space ramped up on the social media channels. Some people are all for commercializing space, while others disapprove of anything that smacks of space tourism for rich folks. I get that. We actually discussed it on the Weekly Space Hangout last week. Part of the conversation focused on the idea that it’ll be a long time before “regular folks” go to space. For the time being, rides to space are limited to the folks who can pay for it. Or, the folks are being sent by government agencies.

Surprise: It’s Not a New Idea

In truth, space has been commercialized for a long time. You could look at it one way and realize that the involvement of commercial enterprises has always been there. Who do you think built spacecraft for NASA? Aerospace companies. And that was the first step toward commercializing and industrializing space. That hasn’t changed. There are many companies involved in space and always have been. And, the whole New Space movement is predicated on younger, nimbler companies stepping up to do the business of space. A Harvard Business Review article published earlier this year pointed out that there are actually two main parts to the “space sector”—what they call “space for Earth” and “space for space.”

In “space for Earth”, companies are involved in creating goods and services produced in space for use here on the ground. That includes some very venerable “product”: Earth-observing satellites, national security assets, and research done on orbit (such as on the ISS).

Newer activities, such as the launch of Starlink (to provide Internet access), and advanced telecommunications, comprise others. It seems like there’s a Starlink or other launch every week or so. This ready access to space by SpaceX, ULA, RocketLab and others benefits from decreased launch costs for hardware, and so on. That’s really helped, for example, the satellite industry.

What’s the Future of Space Commercialization?

The future of space tourism and asteroid mining and the creation of goods and services produced in space for use on orbit, or on the Moon, or on the way to Mars—that’s a little farther out. I’m talking about things like building habitats, supply stations or research stations, bases for asteroid exploration, or jumping-off points to Mars, for example.

One other thing that I want to say is that while there is a lot of scoffing going on about the rich guys flying in space, the advent of space tourism isn’t that far away. And, if you can make money transporting the non-rich folks up for a suborbital or a quick stay at a station, there’s nothing stopping you from transporting folks who want to live and work in space—and that’s going to spur on a lot of other businesses.

We’re already seeing the seeds of this in the current commercialization—and that commercialization started way back in the 1960s. We maybe just didn’t realize it at the time. But, like it or not, the era of space commercialization is now entering new levels of investment in both funding and human capital.
