calculateDeltaV: function(data){
    var radiusOfBody = data["b.radius["+ this.vessel.orbitingBody.id +"]"]
    var r1 = data['o.ApA'] + radiusOfBody
    var r2 = data['tar.o.ApA'] + radiusOfBody
    var mu = data["b.o.gravParameter["+ this.vessel.orbitingBody.id +"]"];

    var factor1 = Math.sqrt(mu/r1)
    var factor2 = Math.sqrt((2 * r2)/(r1 + r2))

    this.deltaV = factor1 * (factor2 - 1)

    // console.log("delta V1: " + this.deltaV)
