No worries! As did I at some point in my life. So if you watch “The Martian” with Matt Damon - great movie, awesome book - the whole concept of the dust storm pushing the escape vehicle over and blowing a radar dish into Mark Watney is complete BS. Andy Weir tried to keep most things true to the science / believable, but I think I’ve read somewhere that he regretted that whole part because it is just not what Martian Wind is capable of doing.

Can't get much more effective than a missile that does the aiming for you. Since missile tech has already had a lot of funding/testing over the years, the missiles become cheaper to manufacture/sell, meaning which means you can just throw more bombs at the problem for the same amount of money.

Could make a really big laser if we just divert a little bit of the military budget though...

The Martian Atmosphere is incredibly sparse / low pressure. Even the fastest wind on Mars wouldn’t be able to move much besides dust. There’s just not enough molecules of atmosphere to enact significant force into anything of substance.

This is part of the reason why the Ingenuity drone’s blades have such a high revolution rate.

  • Banking would stop due to loss of timing from GNSS. This has immediate and global ramifications.
  • Some disruption to air traffic control as space based ADSB is lost and only available near airports.
  • Global sea shipping loses tracking. Most navigation. Global disruption to bulk international supply chains until inertial nav and alternates are reinstalled.
  • Military communication and some crypto is lost. Many many intel sources are lost. Most guided munitions are hampered, deterrence is lost in some cases, likely leading to conflict sparking as adversaries try to make use of the more even power equations. SBRS no longer provides nuclear deterrence.
  • Weather prediction is significantly impacted. This has flow on effects to logistics, insurance and risk management. Military operations and rescue services are significantly impacted.
  • Hubble is lost.
  • TESS, Kepler, Chandra etc are gone, setting back some fields of astronomy.
  • Astronauts, cosmonauts and taikonauts die as the ISS and Tiangong are inhabited satellites. All research aboard is lost.

I'll add to his comparison. It's like taking widely scattered of wood chips from your expensive garden to the south pole, where you plan to build your own reprocessing facility to turn the chips into chipboard to build your Antarctic base.

It's such a huge amount of effort for so little gain
