Advanced Rocketry

Advanced Rocketry is a mod created by zmaster587. It adds custom rockets to travel to asteroids, planets, space stations, and satellites. Its machines use Redstone Flux and multiblock structures for most of its devices.

One tool of note is the Holo-Projector, which allows players to create a virtual 3D schematic of the structure they are building. Scrolling with the mouse wheel while holding shift when holding the Projector will cycle through block layers or display all at once.
