NASA We’re planning to fly over the vast Atlantic with our Global Hawk - once again looking at the dust and dry air from the Sahara. Takeoff on Saturday morning and landing on Sunday morning. We’ll fly from Wallops to a point near the Cape Verde Islands (just off of Africa) and back in about 25 hours. It took Columbus 5 weeks to sail from the Canary Islands to the New World! One of our key instruments is called the Airborne Vertical Atmospheric Profiling System or AVAPS.  Actually,...
