It’s already the sol (Martian day) at Jezero Crater when @NASAPersevere will land!

Mars time is it’s own wild thing, but we establish a local time of noon when the sun would on average be overhead, and a Sol 0* on the day of landing. @NASAPersevere will land at about 3:53 pm local time (so on Sol 0, it’s really close to Eastern time)

*fun fact: I chose Sol 0 for the landing day on @MarsCuriosity with my colleague John Gilbert as it wasn’t consistent across all Mars missions. I’m guessing it’s now heritage for @NASAPersevere!

The wild thing about the sol being nearly 40 minutes longer than the day is that every day you’re moving almost a full time zone. There’s a reason they gave us “I survived 90 sols” badges for the team after working on Martian time
