Greetings from Mars! Did you know that the dust here tastes just like dried ketchup? Our annual sandstorm festival is an experience like none other. We're still waiting for those terraforming applications to process, but in the meantime, a hearty "Hello!" from dusty solitude.
Love from the lava tubes,

Hi from Venus! Imagine a global sauna but with more sulfur and less charm. The temperature's perfect for baking cookies — if you can withstand the acid rain. Our humidity levels are off the charts, but who needs dry air anyway?
Clouds of gas and warmth,

Proxima B checks in with a cautious wave! Life here is a tad slow, but the sunsets over the alien flora are Instagram-worthy if you've got time to set up. We've lobbied hard for gravitational rights, and the lobbying snack program is top-notch.
Gravity agnostic attitudes,
