It's been a while since I posted anything, but with school coming to an end, grading and finishing year-end tasks this has taken up most of my time. With that said, let's dive into my new topic on Mars: Global Blackout.
As many of you know, Mars is experiencing a major dust storm which has caused problems with the Curiosity Rover. As depicted in the Mars miniseries, Mars experiences dust storms that can kick up enough material to block the Sun. These storms are normally seasonal and occur when Mars orbit is closest to the sun (called perihelion). What makes this storm unique is that it has spread so large it encompasses the entire planet as it has now. The previous time this happened was in 2007 (Byrd, 2018).

As you can see in the picture, sunlight is having a difficult time penetrating the storm.
With the ongoing storm, the Opportunity Rover may go dead since it can not recharge its batteries from solar power. Curiosity does not have this problem since it has nuclear power to keep it alive. This creates an incoming problem for the Insight mission which was launched in May. If Insight must land during this storm, NASA will need to modify its landing procedures in order to counter issues associated with the storm.
With these challenges come new discoveries. NASA was able to study the 2007 dust storm and determine a link with gas escaping the Mars atmosphere. NASA's MAVEN mission is situated to further this study in learning about Mars atmosphere (NASA, 2018). Additionally, there are the Mars Reconnaissance Orbiter, Mars Express, and Mars Odyssey which will provide valuable research data as they continue to study both Mars atmosphere and surface.
One final thing to consider is the effect such weather has on astronauts that first arrive and settle on Mars. As depicted in the Mars miniseries, one of the biologists was so severely affected psychologically that he opened a hatch door which caused decompression and death. Could such an event happen in real life and what precautions will NASA take to ensure this does not happen? I'm sure each of you has been affected by the weather in some way or another. Too much rain brings depression. I saw that while living in Seattle. But when the Sun came out, it was like living in paradise. Others are affected by winter weather. How will astronauts handle the pressures associated with a mission so far from Earth and how will these dust storms make this worse. What are your thoughts? How would this affect you?
