The signal
A handful of servicing missions have successfully docked with and extended the life of commercial satellites. Several companies are building refuelling and inspection spacecraft.
Where it could lead
If satellites can be maintained, they last longer and cost less. It also helps clean up space debris, which is becoming a real risk as orbits get crowded.
Evidence that would strengthen the case
- Satellites are routinely designed to be refuelled or serviced
- Several paid servicing missions per year, not one-off demonstrations
- Insurance and space agencies treat servicing as a standard option
What could prevent it
- Servicing costs more than simply launching a new satellite
- A docking accident creates debris and scares off customers
- Cheap launch makes disposable satellites the easier choice
