Key Terms
Satellite Refueling
Satellite refueling startups pioneer in-orbit servicing by extending satellite lifespans through propellant transfer, reducing the need for costly replacements and mitigating space congestion. Space debris cleanup companies concentrate on removing defunct satellites and fragments to preserve orbital safety, yet satellite refueling directly enhances satellite operability and economic value. Explore the latest innovations and market leaders revolutionizing satellite refueling technology.
Active Debris Removal
In-orbit servicing companies specialize in maintaining satellites by refueling, repairing, or upgrading them to extend operational life, whereas space debris cleanup startups primarily focus on active debris removal (ADR) to mitigate collision risks with defunct satellites and fragments. ADR techniques involve capturing or deorbiting space debris using nets, harpoons, robotic arms, or propulsion systems, effectively reducing orbital congestion in heavily trafficked low Earth orbit (LEO) regions. Explore key innovations and leading startups driving breakthroughs in active debris removal technologies to better understand this critical space industry segment.
On-orbit Servicing Contracts
On-orbit servicing startups secure contracts to extend satellite lifespans through refueling, repairs, and upgrades, leveraging advanced robotics and AI for precise operations. Space debris cleanup companies focus on removing defunct satellites and fragments to mitigate collision risks, often partnering with governments for regulatory support and funding. Explore the latest on-orbit servicing contracts and innovations shaping the space industry's sustainable future.
