RETALT (RETro Propulsion Assisted Landing Technologies) is a project for aiming to investigate in key technologies for
retropropulsion reusable launch system
A reusable launch vehicle have parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boost ...

The reference configurations for the development of the targeted technologies are two types of vertical launch and landing rockets a
two-stage-to-orbit
A two-stage-to-orbit (TSTO) or two-stage rocket launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between a three-stage-to-orbit launcher and a hyp ...
and a
single-stage to orbit
A single-stage-to-orbit (SSTO) vehicle reaches orbit from the surface of a body using only propellants and fluids and without expending tanks, engines, or other major hardware. The term usually, but not exclusively, refers to reusable vehicles ...
