The Take

Uses skyfield to compute the current one-way light-time to Mars and inserts that latency into an LLM-backed chat, which is a neat little realism hack that actually changes the interaction rhythm. It's a fun, well-focused demo — charming for a minute or two — but it's mainly a novelty (and gated behind an account/token model), not something that redefines chatbots.

Post Description

Hello!

This is a silly little thing. It uses the skyfield python library to get the current light travel time to Mars so we can make this as accurate as possible. It's meant to simulate a conversation between you and someone on Mars with the correct communication delay. (Yeah, it's vibecoded, but still very fun). Since there is nobody on Mars (yet), an LLM is backing the conversation on the other side posing as a humanoid robot.

Sorry for the login requirement, but I want to protect from out-of-control token costs. The model behind it is full gpt-5.2.

I made this because I've always wanted to make it but never really wanted to put in the effort. Luckily, stuff like this is a lot easier to make now, so I get to have fun making all my project ideas that I wouldn't have otherwise made.

Have fun chatting with a 'Martian robot' with actual time delay to Mars!
