re hst servicing mission scheduled for days in article rq os i access digex net prb access digex net pat writes in article t nhg rpi edu strider clotho acm rpi edu greg moore writes as herny pointed out you have to develop the thruster also while much lighter you still have to lift the mass of the thruster to orbit and then the thruster lifts its own weight into a higher orbit and you take up room in the payload bay a yes but the improvement in boost orbit to the hst is significant i do not understand what you are saying here what is improved what is significant and what does this have to do with carrying more equipment on a servicing mission also as implied by other posters why do you need to boost the orbit on this mission anyway maybe you have something here but could you please clarify it for us on the net and that means you can then carry edo packs and enough consumables so the shuttle mission can go on long enough to also fix the array tilt motors and god knows what else is going to wear out from what i ve heard the motors are fine it is one of the two sets of electronics that control the motors that needs a fix the motors and electronics are separate pieces of hardware i expect to be corrected if i m wrong on this on the hst in the next months pat
