One of the most iconic events in history is Apollo 11 landing on the lunar surface. During the descent, astronauts Neil Armstrong and Edwin “Buzz” Aldrin are heard relaying commands and data back and forth to mission control across 385,000 kilometers (240,000 miles) of outer space as the lunar module “Eagle” slowly inched its way into the history books.
In the final moments before touchdown, Aldrin can be heard saying, “Picking up some dust”, followed by large dust clouds shooting outward from underneath from the spacecraft as the exhaust plumes interacted with the lunar surface, more commonly known as brownout or brownout effect. This significantly reduced the visibility for Armstrong and Aldrin as they landed, and while they successfully touched down on the Moon, future astronauts might not be so lucky.
Space exploration requires all kinds of interesting solutions to complex problems. There is a branch of NASA designed to support the innovators trying to solve those problems – the Institute for Advanced Concepts (NIAC). They occasionally hand out grant funding to worthy projects trying to tackle some of these challenges. The results from one of those grants are now in, and they are intriguing. A team from Masten Space Systems, supported by Honeybee Robotics, Texas A&M, and the University of Central Florida, came up with a way a lunar lander could deposit its own landing pad on the way down.
