NASA’s InSight Mars lander keeps daily records of weather conditions at the Elysium Planitia landing site on the red planet. Last week saw daytime highs from 8 to 15 degrees Fahrenheit; lows fell to -139 degrees.

Seasons are twice as long on Mars as on Earth because the Martian year is 687 days; almost double an Earth year.

Mars doesn’t have months like we have months though. Our concept is based on a lunar orbit. Mars’ moons orbit much faster – Phobos every 8 hours, Deimos every 30 hours; so well over 2,000 orbits per 30 day ‘month’ for Phobos and over 500 orbits per ‘month’ for Deimos.

InSight landed Nov. 2018 on a two-year mission to better understand the interior of Mars using both surface and drilling geophysical sensors.

Turning to night sky highlights this week:

Mars, Jupiter, and Saturn have the morning sky at 6:00 a.m.; Venus has the evening at 6:00 p.m. We’re gaining 2.5 minutes of sunlight per day through March.
