With computers and technology becoming lighter and is also effected by drag. Could a small satellite that lacks certain systems be designed to utilize an existing satellites systems like radio, solar cells and other equipment? By utilizing old hardware could weight on launch be reduced because the heavier weight needed to stay in orbit longer is already there?

  • $\begingroup$ What is that: "gaining weight on arrival"? Arrival to what? $\endgroup$ – peterh Dec 19 '18 at 2:13
  • $\begingroup$ Probably a starting point for this question is 'how much mass is consumed by the computer'. First order guess is that the %CPU mass of existing satellites is low - the life time is limited by propellant, the batteries and eventually the solar cells so things that replaced those on orbit would offer advantages but that not where this question is going. $\endgroup$ – GremlinWranger Dec 19 '18 at 6:06
