The Space Debris Crisis

Kessler Syndrome

First proposed by NASA scientist Donald Kessler in 1978, the Kessler syndrome describes a cascading chain reaction in which collisions between orbiting objects produce fragments that cause further collisions. Each impact generates hundreds or thousands of new debris pieces, exponentially increasing collision risk. Beyond a certain density threshold, the process becomes self-sustaining, rendering entire orbital bands effectively unusable for satellites and crewed missions.

Current Tracking Falls Short

Today's space surveillance networks rely primarily on ground-based radar and optical telescopes. While capable, these systems face fundamental limitations: weather dependence, limited observation windows, and resolution that degrades rapidly for objects smaller than 10 cm. The US Space Surveillance Network tracks approximately 27,000 objects, but the estimated population of debris larger than 1 cm exceeds one million.

Conjunction warnings (alerts that two objects may collide) arrive with limited precision. Operators frequently receive warnings just 12 to 24 hours before a potential collision, leaving time only for emergency avoidance maneuvers that burn precious fuel and disrupt mission timelines.

Why Existing Solutions Fall Short

Active debris removal missions (net capture, harpoons, robotic arms) target a handful of large objects per mission at costs measured in hundreds of millions. They address the symptom, not the cause. Without dramatically better tracking, situational awareness, and early intervention, the debris population will grow faster than any removal campaign can shrink it.

The missing piece is precision, actionable data delivered early enough to make intelligent decisions. That is the gap ExoPulse fills.
