[InSight's Final Selfie] The InSight lander is in the final stages of of its extended mission. This image, taken on April 24th 2022, is it's last selfie.

There was a possibility to keep going until the last operating science experiment had to be turned off, and then InSight would keep operating on safe mode until it eventually ran out of power.

Explanation of the Wind Speed Chart
Wind speed is shown in meters per second, as measured by the pair of TWINS booms. The barbs extending from each wind speed data point indicate the compass direction of the wind (e.g., a wind blowing from the north will have a barb straight up above the point; a wind blowing from the west will have a barb off to the left). Full and half flags extending from the barbs indicate the wind speed, with each half flag representing approximately 2.5 meters per second. A circle in place of a barb indicates a wind speed less than 2.5 meters per second.

Note: There is a discrepancy between the summary data and the charts provided by NASA (good on you if you spotted this - if not, go hunt the thimble!). I've notified them and hopefully they'll do something about it.

To put wind speed in perspective, the dust on Mars is talcum-powder fine. It requires a wind speed of 64kph (~40mph) to pick it up. 64kph equates to approximately 17.78m/s. The air is incredibly thin, just 0.06% the density of Earth's atmosphere at sea level, so it takes a high wind speed to generate enough Newtons to pick even these tiny particles up.

Typical air pressure on Earth is around 1000mb = 1bar = 100,000 pascals.

The Martian day is 39 mins 35.244 secs longer than a standard day. This means that approx every 36.1 days the Earth date skips a day while the Martian Sol marches on as normal. You can see this in the data below. April 16th 2019 seems to be missing, yet the Sols on April 15th and April 17th are consecutive.

Wind distribution graphs indicate from which directions wind was most prevalent during the course of a day. You can select from the last 30 days worth of data (first detailed wind direction data is for sol 539).

Data gathered from the NASA servers may be subject to corrections based on newer data. This is performed by NASA, not me. Any data that is within the last 7 data-rows is within the frame that may be updated. Any updates are automatically applied to the tables below, and all charts and derived tables (such as the record high and low temperatures) are updated accordingly.

Some tables show results after smoothing the data to remove anomolies. I have clearly marked all data that has been smoothed so there is no ambiguity. The method of smoothing out the anomolies is simple and efficient, although not guaranteed to remove them all. Essentially, if a temperature reading is ≥±10°C from the previous valid reading, it's probably an anomoly and is rejected.

This webpage will soon be converted to be the top level page for Mars Weather Reports. It will contain links to the sub-pages, the clocks, the current location of Mars graphic and other data not spcific to the weather readings. The sub-pages will display the weather data from Insight, Curiosity and Perseverance..
