Why must we use rocket propulsion systems in space, rather than another method to create the rocket's movement? O While usable, there are too few particles in space for a propeller to be as effective as we want. о There is nothing to push off of in space, so you must throw stuff in the other direction to move forward. O Rocket propulsion systems are the most durable and can handle coming in and out of Earth's atmosphere. 4 Rocket propulsion systems are simply the most affordable and, therefore, help meet NASA's budget.

consider plutoz diameter and mass. (2374)km & (1.303E22kg) and day which js 6.4 dayz long. FIND: 1. please elaborate how would you get the answer to the escappe vel0city from plut0. 2. we would need to find the minimum energy required for an aircraft or ship of some sort with mass (525kg) to escape this planet.. 3. we would also need to find the t0tal energy for a complete orbit around the planet with an airship with a same mass (525) and an altitude of 224 km
What would this one be and why?
