A Northrop Grumman Antares rocket carrying a Cygnus resupply spacecraft is in the vertical launch position on the Mid-Atlantic Regional Spaceport’s Pad-0A, Tuesday, Feb. 16, 2021, at NASA's Wallops Flight Facility in Virginia. Northrop Grumman’s 15th contracted cargo resupply mission with NASA to the International Space Station will deliver about 8,000 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew. The CRS-15 Cygnus spacecraft is named after NASA mathematician, Katherine Johnson, a Black woman who time and again broke through barriers of gender and race. The launch is scheduled 12:36 p.m. EST, Feb. 20, 2021. Photo Credit: (NASA/Patrick Black)

30 calibabor Vertical Gun Range in horizontal loading position. Dr. William Quaide and Donald Gault of Ames planetology branch used this gun range to study the formation of impact craters on the Moon. N-204A Verticle Gun is used to simulate the physics and mechanics of planetaryimpact cratering phenomena.
