On 7 October 2020, Warren Eshpeter, founder of Let's Go to Space, Inc., presented an online talk on satellite engineering and design.
Engineering for the Void
"Building spacecraft that can survive launch vibrations, operate in vacuum, and maintain functionality through extreme temperature swings."
The session walked through the practical challenges of building spacecraft that can survive launch vibrations, operate in the vacuum of space, and maintain functionality through extreme temperature swings.
The CubeSat Revolution
Eshpeter explained how modular CubeSat platforms have democratized space access, enabling universities and startups to deploy scientific instruments and communications technology at a fraction of traditional costs.
What Makes CubeSats Special
- Standardized form factor: 10cm cubes that can be stacked
- Lower launch costs: Ride-sharing reduces expenses dramatically
- Rapid development: Universities can build missions in 2-3 years
- Educational value: Students gain hands-on spacecraft experience
- Scientific capability: Despite their size, CubeSats enable real research
From Concept to Orbit
The talk covered the entire lifecycle of a small satellite mission:
- Design phase: Defining mission objectives and constraints
- Component selection: Choosing sensors, radios, processors, and power systems
- Testing: Vibration, thermal-vacuum, and electromagnetic compatibility tests
- Integration: Assembling the satellite and validating all systems
- Launch: Securing a ride to space and deployment procedures
- Operations: Commanding the satellite and downloading data
This practical overview demystified satellite engineering and showed how space technology has become accessible to a new generation of students and entrepreneurs.
