NASA has been without its own launch vehicle since the retirement of the Space Shuttle in 2011. That won’t be the case for much longer. The agency hopes to begin flying the Space Launch System (SLS) in 2020 without a crew, and manned missions to deep space could start as soon as 2023. It’s actually looking more likely NASA will be able to stick to that schedule, but with a less powerful version of the rocket. According to NASA administrator Robert Lightfoot, NASA now plans to use the Interim Cryogenic Propulsion Stage for early manned flights.
