This week with astronomer David Reneke, we’re covering the full spectrum of space activity — from a faint comet you can actually try to spot from Australia before sunrise, through to the next wave of global space missions, and even NASA’s early plans for a nuclear-powered Mars mission in 2028.

It’s a mix of what’s happening right above us… and what’s coming far beyond Earth.

We’ll break down:
• Comet C/2025 R3 (PanSTARRS) lighting up the pre-dawn sky (if you’ve got binoculars and patience)
• Why space exploration is shifting into a faster, more crowded “many missions at once” era
• NASA’s bold concept for nuclear propulsion and Mars helicopters
• And what all of this actually means for the next decade of space science

David, as always, helps cut through the hype and explain what’s real, what’s emerging, and what’s still just engineering ambition.
