Episode notes
Hubble Asteroid Hunt Yielded 1,701 Trails
- Citizen scientists found 1,701 asteroid light trails in Hubble images from 2002–2021.
- Over 1,000 of those trails are previously unassociated faint asteroids, mainly in the main belt.
Combine Citizens And ML For Better Discoveries
- Use community classifications to train machine learning and amplify discoveries.
- Combine volunteer identifications with algorithms to uncover faint objects missed in initial searches.
Dust Threatens Solar Rover Health
- Martian dust and seasonal sunlight changes threaten small solar-powered explorers in winter.
- Teams must plan charging strategies and communications priorities to maintain operations through dust season.
