Questions & Answers

Q: Why is SpaceX involved in lawsuits with Blue Origin?

SpaceX won a NASA contract for a moon lander with Starship, leading to legal challenges. Blue Origin sued, arguing for fair consideration and competition.

Q: How does telescope resolving power scale with size?

Larger telescopes gather more photons, enabling better resolution and making fainter objects visible by collecting and concentrating light effectively.

Q: What unique interview approach would Fraser take with Elon Musk?

Fraser prefers interviews with lesser-known space industry experts focusing on technical details, insights, and fresh perspectives over famed personalities like Elon Musk.

Q: Can dark matter be tiny black holes?

Dark matter theories include tiny black holes, plausible from gravitational lensing events, although mainstream astronomy leans toward a particle nature for dark matter.

Q: How could a hot air balloon function on Mars?

A proposed concept involves a balloon inflating during the warmer Martian daytime, lifting the package it carries, and then deflating at night to rest until daylight resumes the flight.
