Description:

TDO is a twelve-unit CubeSat carrying a space debris investigation and tracking experiment.

Mission details:

ULA′s Atlas V flight AV-083, using the powerful 551 model, was launched on Aug 8, 2019. Centaur AV-083 made three burns to a high perigee GTO to drop off the strategic US military communications satellite AEHF 5.
After the second burn, a 12U cubesat called TDO was ejected into geotransfer orbit. TDO, for the USAF Space and Missile Command, tests satellite and space debris tracking technologies.
