Martian Dust Devil
|
Ah, Martian Summer! Finally, the days are long, just like on dear old Earth. And daytime highs rocket all the way up to a balmy 20°C (68°F) from the Summer nighttime low of -90°C (-130°F), meaning you and your fellow astronauts can warm up your machinery earlier to get a good start on mining operations.
But those warm daytime temperatures also bring alive the Martian devils. Dust devils, that is.
You were caught in one just yesterday - and a devilishly terrifying experience it was! This was no little Arizona desert whirlwind, only a few tens of meters high and a few meters across and past you in seconds.
No, what hit you yesterday was a monster column towering kilometers high and hundreds of meters wide, 10 times larger than any tornado on Earth. Red-brown sand and dust whipping around faster than 30 meters per second (70 miles per hour) dropped visibility to zero, scouring your faceplate, driving dust into every fold and wrinkle of your spacesuit.
For 15 minutes you huddled and endured the buffeting. The scariest part was the incessant crackling and flashing of miniature lightning bolts nipping at you and your rover, and the loud static on your radio that prevented you from calling for help.
Could this really happen?
