RETALT

RETALT (RETro Propulsion Assisted Landing Technologies) is a project for aiming to investigate in key technologies for retropropulsion reusable launch systems established in March 2019 with funds from the European Union's Horizon 2020 program. It aims to "advance the research and development of key technologies for European vertical-landing launch vehicles."{{cite web|url=https://www.retalt.eu/project/|title=RETALT|author=|date=11 February 2018|website=RETALT|accessdate=26 June 2019}}{{cite web|url=https://arstechnica.com/science/2019/06/europe-says-spacex-dominating-launch-vows-to-develop-falcon-9-like-rocket/|title=Europe says SpaceX "dominating" launch, vows to develop Falcon 9-like rocket|first=Eric|last=Berger|date=26 June 2019|website=Ars Technica|accessdate=26 June 2019}}{{cite web | url=https://www.futura-sciences.com/sciences/actualites/lanceur-reutilisable-dlr-veut-lanceurs-reutilisables-plus-performants-falcon-9-76593/ | title=Le DLR veut des lanceurs réutilisables plus performants que le Falcon 9 }}

The reference configurations for the development of the targeted technologies are two types of vertical launch and landing rockets a two-stage-to-orbit and a single-stage to orbit .{{cite web|url=https://www.retalt.eu/project/|title=RETALT|author=|date=11 February 2018|website=RETALT|accessdate=26 June 2019}}{{cite web| url=https://rocketrundown.com/european-consortium-brazenly-announces-plans-to-copy-falcon-9/| title=European Consortium Brazenly Announces Plans to Copy Falcon 9| last=Andrew Parsonson|date=26 June 2019|website=rocketrundown.com|accessdate=26 June 2019}}{{cite web| url=http://www.spacedaily.com/reports/European_reusable_launch_systems_for_more_sustainability_in_spaceflight_999.html| title=European reusable launch systems for more sustainability in spaceflight| website=Space Daily}} The partner organisations are DLR, CFS Engineering (Switzerland), Elecnor Deimos (Spain), MT Aerospace (Germany), Almatech (Switzerland) and Amorim Cork Composites (Portugal).{{cite web|url=https://www.dlr.de/dlr/en/desktopdefault.aspx/tabid-10081/151_read-36131/|title=RETALT project European reusable launch systems for more sustainability in spaceflight|last=DLR|date=|website=DLR Portal|accessdate=26 June 2019}}{{cite web | url=http://www.elecnor-deimos.com/portfolio/retalt/ | title=RETALT }}{{Cite web|url=https://cfse.ch/projects/european-projects/|title=European projects|date=2018-12-10|website=CFS Engineering|language=en-US|access-date=2020-02-13}}{{Cite web|url=https://almatech.ch/almatech-is-part-of-reusable-landing-rocket-retalt/|title=Almatech is part of the European project for the development of a Reusable Landing Rocket (RETALT)|date=2019-06-24|website=Almatech|language=en-US|access-date=2020-02-13}}{{Cite web|url=https://amorimcorkcomposites.com/en-us/about-us/news/cork-integrated-within-programme-for-reusable-space-vehicles/|title=Cork integrated within programme for reusable space vehicles|last=Portugal|first=Fullsix|website=Amorim Cork Composites|language=en-US|access-date=2020-02-13}}
