Episode notes
SpaceX's Financial Motivation
- SpaceX needs to substantially increase revenue to justify its high valuation.
- Entering the broadband internet market via Starlink is their strategy to achieve this.
Satellite Photobomb
- Astronomer Victoria Gerges was showing visitors galaxies at Lowell Observatory when 60 Starlink satellites photobombed her camera.
- The satellites created streaks, obscuring the view and highlighting the impact of satellite swarms on astronomy.
LSST's Challenge
- The Large Synoptic Survey Telescope (LSST) aims to capture a comprehensive view of the universe by taking pictures of the entire sky every night for 10 years.
- The streaks from Starlink satellites threaten to disrupt the LSST's observations.
