NASA has a new propulsion system that runs on water, actually Brown gas or HHO. For the microsatellites that are lifting as excess cargo allows, they have been forced to stay and the release Orbit.

This is the propulsion system that will allow them freedom of movement.

This is the new propulsion motor, that will allow them independent movement. It uses solar panels, to break down water into hydrogen and oxygen; which they store on board until needed, and inflatable bladders. The fuel once stored, is used in this rocket engine both to burn, and 2 superheat the remaining water. This allows them to use the burning gases, and the superheated steam for propulsion.
This allows the micro satellite to be inert when launched with the pressurized gas on board, yet they can carry enough fuel for about 3 years of operation. NASA is looking at actually using the same propulsion system, and some of their larger satellites; due to its high efficiency. This will allow some of the satellites made at universities Etc.; to expand their function significantly, by being able to move to where the testing needs to be done.
While this is not an ion drive, it is a significant step in that direction; with large Drive efficiency gains. This is definitely a step forward for space exploration. Since the energy to break down the water into Brown gas or HHO comes from solar panels, it's very close to free rocket fuel!
Impressive design using a simple concept( HHO) that we've known about for a century, in an entirely new way! I expect this may be added two space stations first stabilizing Jets. Is it can use recycled Wastewater for rocket fuel; instead of the fuel that must be lifted from the Earth's surface currently.
Much more cost effective than the current method, and also safer. This technoligy will change all future space flights, but few people will even notice the change, SMH!
Engineers always chase the elegant design solutions, but it is always an elusive target! This design solution is elegant, and this design group is to be congratulated.
