Episode notes
Sun's Shield And Incoming Threats
- IMAP will study how the Sun both accelerates the solar wind and samples material entering our heliosphere.
- The mission helps reveal how the Sun's magnetic bubble protects the inner solar system from more dangerous galactic radiation.
Fleet Approach To Space Weather
- NASA coordinates multiple heliophysics missions like Parker and IMAP to sample the solar wind from different locations.
- Combined observations act as multiple eyes to monitor space weather and protect Earth.
Telescopes Tighten Dark Energy Constraints
- New observatories like Vera Rubin and the Nancy Grace Roman telescope will map dark matter and measure cosmic expansion precisely.
- These measurements narrow what dark energy could be by revealing how expansion changed over time.
