Episode notes
Sasha's 29 Year JPL Career And Key Missions
- Alexander Ermenko (Sasha) spent 29 years at JPL across roles from support engineer to chief engineer.
- He worked on missions including Rosalind Franklin Rover (ROSA), Mars Sample Return, Europa Clipper, SMAP, Curiosity, and instrument Aquarius, illustrating broad hands-on mission experience.
Why Early Russian Spacecraft Favored Autonomy
- The Russians designed early spacecraft to be autonomous because pilots lacked reference cues in space and human inputs could degrade control.
- Sasha relays that Russian engineers prioritized autonomy and sometimes opposed pilot demands to retain automation.
Principal Mechanical Engineer Is Architect Problem Solver And Mentor
- The principal mechanical engineer role blends architecture, problem solving during detailed design, and mentoring of engineers.
- Sasha emphasizes mentoring to preserve institutional knowledge and accelerate on-the-job learning that colleges can't provide.
