NASA’s Gulfstream III and Gulfstream V fly over the San Jacinto Monument just outside of Houston on Aug. 28, 2018. The two planes have been modified to support a variety of scientific missions, including activities such as mapping lava flows from active volcanos and measuring the levels of ice melting at the Earth’s poles. The photo was taken from one of NASA’s T-38.
