Questions in orbit
Answers begin with the conditions that make a claim true. Select a question to expand the assessment.
Can we remove all debris with one technology?
No. Targets differ in size, orbit, material, rotation and ownership. A method suitable for a prepared satellite may be unsuitable for an uncooperative rocket body or a small fragment. Start with target characterisation.
Why not collect the smallest fragments first?
Small fragments can be dangerous but are often difficult to track and rendezvous with individually. Removing selected large objects may reduce future fragmentation sources rather than directly collecting every existing particle. This is one reason a useful metric considers future risk, not only the number of items removed.
Does a capture demonstration prove a removal service works?
Not by itself. Evidence must identify the target, preparation, approach, capture, stabilisation and disposal steps actually completed. A controlled experiment can be valuable while leaving important parts of a commercial mission unproven. Compare the contact methods.
Can a magnet attach to any satellite?
No. Magnetic capture depends on a compatible interface or suitable material, geometry and separation. Many spacecraft surfaces do not provide a universal magnetic attachment point. Prepared docking plates make a different engineering problem from capture of legacy debris.
Will every object burn up during re-entry?
No. Some components may survive. Re-entry analysis must consider material, construction, breakup behaviour, trajectory and risk to people and property. A disposal plan should address these consequences rather than assume that atmospheric entry makes all material disappear. Read the disposal assessment.
Are laser removal systems established cleanup services?
They should not be described that way without evidence of the claimed service. Proposed approaches differ and face constraints involving power, pointing, target response, safety and permission. Photon-pressure concepts and material-ablation concepts should not be treated as the same mechanism.
Can anyone salvage an inactive satellite?
No automatic salvage right follows from inactivity. Ownership, registry, national authorisation, consent and liability must be assessed. An object’s lack of function is not a legal permission to touch it. Review responsibility and authority.
Is there a standard price per object?
No universal price is meaningful. Target orbit, mass, navigation difficulty, capture requirements, mission architecture, disposal and insurance can change the cost substantially. Public contract values may also cover research or demonstration work rather than a repeatable service price.
Does removal replace prevention?
No. Passivation, reliable end-of-life disposal, collision avoidance and debris-conscious design remain essential. Removal addresses selected existing risks. New fragmentation events can undo progress, which makes prevention and removal complementary rather than competing strategies.
