(************************************************************************************************************** )finding a fascinating cloud in an image taken the other day; unlike something intriguing on the surface area, more observations simply aren’t possible, as it’s long passed now.Or picture attempting to take a motion picture of a dust devil zooming throughoutJezero crater, when the rover’s everyday activities are all planned before the rover even awakens.
The reality that lots of climatic phenomena are short-term and/or difficult to anticipate, and typically only happen throughout particular period, implies that climatic researchers on the Mars 2020 group need to utilize various methods to observe them.
Observation Strategies and Tools
Firstly, the sensing units that comprise the main climatic instrument (the Mars Environmental Dynamics Analyzer, MEDA) make meteorological and associated observations continually a minimum of every other hour of every sol. This provides us a great possibility of recording short-term and hard-to-predict phenomena.
Secondly, for sensing units that can’t determine as typically– like the video cameras and microphone– we take measurements over several sols at various times and (for imaging) instructions, to develop stats on when and where intriguing phenomena happen.

Adapting to Environmental Changes
Thirdly, when we anticipate to see something uncommon based upon the time of year or area, we increase the cadence of measurements to ensure we record that occasion. In Perseverance’s very first year on Mars we observed a spreading halo towards completion of Mars’s cloudy season. This intense ring around the Sun is brought on by big hexagonal ice crystals that just form when great deals of water vapor exists. Despite lots of efforts to image another in the 2nd Mars year, it wasn’t up until our last effort– right before the cloudy season ended– that we saw one ( see figure at top of post)!
And lastly, when a longer-lived uncommon occasion is underway, we respond by including more measurements. There are presently great deals of dust storms taking place on Mars, and with some passing right over Jezero we have actually just recently determined the biggest dust opacities of the whole objective to date! So we have actually been taking extra observations to inform us about how the climatic state, dustiness, and regional dust lifting have actually been altering due to this storm activity.
Insights and Discoveries
For much of these observations, we do not understand if we’ll even ‘catch’ the climatic phenomena we’re attempting to study up until we get the outcomes back onEarth But even understanding when, where, and under what conditions something does not happen is really beneficial. And by standing firm, we have actually had the ability to get great observations of whatever from clouds and halos to dust devils and the beginning of dust storms.
