Phobos And Deimos & Mars Environment Phobos And Deimos & Mars Environment Phobos And Deimos & Mars Environment (PADME) is a low-cost NASA Mars orbiter mission concept that would address longstanding unknowns about Mars' two moons Phobos and Deimos and their environment. The PADME mission competed for Discovery Program funding, but lost to the Psyche and Lucy missions. The mission is led by Anthony Colaprete (Principal Investigator). Other principals include Pascal Lee (Deputy Principal Investigator) and Butler Hine (Project Manager). The origin of Mars' satellites, which were discovered by astronomer Asaph Hall, remains unknown.

Mars One is divided among the seven payloads as follows: In 2022, a robotic rover was proposed to be launched to Mars in order to scout a landing site for the 2027 lander and a site for the Mars One colony. At the same time, a communication satellite would be launched, enabling continuous communication with the future landed assets. In 2024, six cargo missions were proposed to be in close succession, consisting of two living units, two life-support units, and two supply units. A spacecraft transporting four astronauts was proposed to meet a transit vehicle bound for Mars. In 2025, the landing
