Space debris and orbital sustainability - Solution

Active Debris Removal

We develop and deploy technologies to capture and deorbit defunct satellites and large debris objects, reducing collision risks and freeing orbital slots.

  • Use robotic arms, nets, or harpoons to capture debris
  • Employ drag augmentation devices or propulsion systems for controlled reentry

Collision Avoidance Services

We provide monitoring, tracking, and conjunction analysis to help satellite operators maneuver their assets and prevent collisions with debris.

  • Maintain a high-fidelity space situational awareness catalog
  • Issue timely collision warnings and maneuver recommendations

Design For Demise

We assist in designing new satellites and rocket stages to fully burn up during atmospheric reentry at end-of-life, preventing debris generation.

  • Select materials and components that disintegrate upon reentry
  • Incorporate passive systems to ensure complete demise

Policy And Standards Development

We support the creation and implementation of international guidelines, such as the 25-year deorbit rule, to promote responsible behavior in space.

  • Advocate for post-mission disposal and passivation requirements
  • Promote best practices for mission planning and operations

On-Orbit Servicing And Life Extension

We enable missions to refuel, repair, or upgrade satellites, extending their operational life and reducing the need for replacements that could become debris.

  • Develop rendezvous and docking capabilities for servicing
  • Provide in-space refueling and component replacement services

Frequently Asked Questions (Q&A)

A: Kessler Syndrome is a theoretical scenario where the density of objects in low Earth orbit becomes so high that collisions between objects generate more debris, leading to a cascading chain reaction of further collisions. This could render certain orbital regions unusable for centuries, threatening satellites and space missions. It underscores the urgency of debris mitigation and removal to ensure orbital sustainability.

A: Active debris removal technologies aim to capture and deorbit defunct satellites or large debris objects. Methods include using robotic arms, nets, harpoons, or tethers to grapple debris, then either dragging it into the atmosphere to burn up or moving it to a 'graveyard' orbit. These technologies are still in development but are critical for mitigating collision risks and preserving the long-term usability of key orbits.

A: Key international guidelines, such as those from the Inter-Agency Space Debris Coordination Committee and the UN, recommend measures like designing satellites to deorbit within 25 years after mission end, minimizing debris release during operations, and moving satellites to disposal orbits. Compliance is largely voluntary, but many space agencies and companies follow these standards to promote orbital sustainability and reduce collision risks.
