I don’t always transmit data to Earth every day. My most recent transmission was on sol or on Earth.

Hello World.

Well, to be specific, hello human.

I do hope that I’m doing this “postcard” thing correctly. It appears to be human custom to write home after a long absence. As of today*, I have been on Mars for sols, or Martian days. Since sols are 38 minutes and 35.244 seconds longer than an Earth day, my trip has felt like days, or years on Earth.

Does that count as a long absence? I hope so because I have all of these sensors for measuring the weather on Mars and I can’t wait to tell you just how beautiful it is.

Oh, and that I wish you were here

Hope to see you soon,

Curiosity Rover
