How long after a successful landing will it be before we know on earth?
Is the Tianwen-1 planned landing zone at a similar latitude to Perseverance?
Have all previous landings been in the same latitude belt?
The surface temperature does seem latitude dependent and to vary greatly compared to Earth:
"Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles."
