Key Terms

orbital service vehicle technical

An orbital service vehicle is a spacecraft that acts like a tow truck and mobile mechanic in orbit: it approaches, inspects, repairs, refuels, relocates or removes other satellites and space debris instead of launching replacements. For investors, these vehicles can lower costs and extend the revenue life of satellites, create new service markets and revenue streams, and change risk profiles for satellite operators and insurers, affecting valuations across the space industry.

thermal testing technical

Thermal testing is the process of exposing a product, component or system to high, low and changing temperatures to see how heat affects performance, safety and durability—like putting a device through hot oven and freezer cycles to check it still works. For investors, it matters because passing or failing these tests affects a product’s regulatory approval, manufacturing costs, warranty risk and likelihood of recalls, which can change revenue, reputation and future cash flow.

vibration testing technical

Vibration testing is a controlled lab process that shakes a device or component to mimic the bumps, drops and motor or road motion it will face in shipping and everyday use. Like taking a product on a rough test drive, it reveals weak parts and failure modes before customers see them. For investors, results signal product reliability, potential warranty or recall costs, regulatory readiness and the risk of production delays that can affect revenue and reputation.

satellite buses technical

A satellite bus is the core platform of a spacecraft that carries the systems needed to operate—things like power, cooling, communications, navigation and structural support—and provides the physical and electrical framework into which mission-specific instruments are installed. Think of it as the chassis and utility systems of a car or the case and motherboard of a computer: it determines how reliable, costly, and flexible a satellite is, so investors watch bus design and production capacity as key drivers of unit price, margins and technological risk.
