> robots on the Moon are literally 3 seconds away (6 seconds round-trip) Moon's apogee (point of furthest distance from Earth) is 405,400km [1]. Speed of light is roughly 300,000km/s [2]. Robots on the Moon are 1.35 seconds away (2.7s round-trip). Even with equipment delays I can't see how you could arrive at 6 seconds round-trip. > Mars [...] is a minimum of 15 minutes away. Mars' aphelion (point of furthest distance from the Sun) is 1.67 AU [3][4]. Earth is about 1 AU from the Sun (by definition). Also, Sun is ~500 light-seconds away from Earth. Thus, at conjunction the distance from Earth to Mars is not more than 0.7 AU or 350 seconds (5.8 minutes).
