Explorer 16 as launched on December 19, 1962, on Wallops Flight Facility, Virginia, United States, with a Scout rocket. MissionExplorer 16 was the second in the series of micrometeoroid satellites orbited by NASA. Its purpose was to obtain data on the near-earth meteoroid environment, thus providing an accurate estimate of the probability of penetration in spacecraft structures by meteoroids and allowing a more confident definition of the relationship between penetration flux and material thickness to be derived. The cylindrically shaped spacecraft, about {{convert|61|x|192|cm|in}}, was built around the burned-out fourth stage of the Scout launch vehicle that remained as part of the orbiting satellite. Explorer 16 carried stainless steel pressurized-cell penetration detectors, impact detectors, capacitor detectors, and cadmium sulfide cell detectors to obtain data on the size, number, distribution, and momentum of dust particles in the near-earth environment. The spacecraft operated satisfactorily during its 7-month life (December 16, 1962, to July 1963), and all mission objectives were accomplished.[1] References1. ^1 2 3 4 5 6 7 {{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraftDisplay.do?id=1962-070A|title=S 55B|work=NSSDC Master Catalog|publisher=NASA Goddard Space Flight Center}} {{PD-notice}} {{Explorers program}}{{Orbital launches in 1962}}{{US-spacecraft-stub}}2. ^{{cite web|url=http://www.planet4589.org/space/log/launchlog.txt|title=Jonathan's Space Page}} 2 : 1962 in spaceflight|Explorers program (NASA) |
