Okay, THAT is slick. Hats off to the team who came up with the idea and made it work.

Default World-first firing of air-breathing electric thruster

"In a world-first, an ESA-led team has built and fired an electric thruster to ingest scarce air molecules from the top of the atmosphere for propellant, opening the way to satellites flying in very low orbits for years on end."

Europe’s first mission to Mercury will soon be ready for shipping to the spaceport to begin final preparations for launch.
The mission passed a major review yesterday, meaning that the three BepiColombo spacecraft, along with ground equipment and mission experts, are confirmed to start the move from ESA’s centre in the Netherlands to Europe’s Spaceport in Kourou, French Guiana at the end of next month. The launch window is open from 5 October until 29 November.

In Sardinia last week, Avio tested the Zefiro 40 (Z40) engine, the second stage propulsion system of the Vega C satellite launcher, an evolution of the current Vega launcher scheduled to lift off for its maiden flight in 2019. This is the first functional test required to qualify this new propulsion system.

Nice graphical display of ESA projects:

Wish they hadn't put the grey text on black background.

New Cosmic Vision 2015-2025 M5 entries!


ESA Selects 3 New Mission Concepts for Study

Quote:
7 May 2018
A high-energy survey of the early Universe, an infrared observatory to study the formation of stars, planets and galaxies, and a Venus orbiter are to be considered for ESA’s fifth medium class mission in its Cosmic Vision science programme, with a planned launch date in 2032.

The three candidates, the Transient High Energy Sky and Early Universe Surveyor (Theseus), the SPace Infrared telescope for Cosmology and Astrophysics (Spica), and the EnVision mission to Venus were selected from 25 proposals put forward by the scientific community.

Theseus, Spica and EnVision will be studied in parallel and a final decision is expected in 2021.

The next years will provide a detailed technical and scientific definition of the three concepts, before one mission is selected to fill the fifth medium-class opportunity in ESA’s Cosmic Vision plan.

Solar Orbiter, Euclid, Plato and Ariel have already been selected as medium-class missions to be launched during the next decade.

CNES’ director of launchers talks reusable rockets.

Seems to be suggesting ESA will be moving to reusable launchers. I don’t see the size of the Themis and Callisto launchers mentioned though. Anyone know the size of these?

Also the article seems to imply they will be phasing out the Vulcain engine, which is too bad. The Vulcain is an excellent engine. Better would be to upgrade it to be reusable like SpaceX did with the Merlin.

See here for the Callisto project, which is not a ESA project, but a cooperation between the ESA members CNES and DLR (Yes, this can be confusing sometimes):

https://www.eucass.eu/doi/EUCASS2017-680.pdf

40 kN thrust of the main engine pretty much limit the maximum takeoff mass to about 3 tons.

EDIT: Here is a paper by the German half of the project:

Very interesting links but I'm skeptical.

I don't see this going beyond demonstration missions.
If successful, ESA would still be years behind SpaceX (and others).

At least in terms of creating a RC Model of a Falcon 9.

But then, they do it with hydrolox because there was a previous project testing the re-ignition in nozzle forward attitude with such an engine. Also this way they can use the existing propellant infrastructure at CSG.

Further on Arianspaceís intention to transition to reusability:

Ariane 6 and beyond.
https://satelliteobservation.net/201...-6-and-beyond/

In a Q & A, itís stated their position towards reusability changed because the coming satellite megaconstellations made it financially feasible.

The European Commission has set out how it wants to spend the next EU space budget.
Officials have proposed spending some €16bn (£14bn) over the years 2021-2027.
The biggest segment, €9.7bn, would go on the further development and maintenance of Europe's sat-nav programmes, Galileo and Egnos.
€5.8bn would fund the Copernicus Earth observation project; and €500m would support secure satellite communications and space environment monitoring.
These two latter activities are new for the EU and go by the names of GovSatCom and Space Situational Awareness (SSA).
Commissioner Elżbieta Bieńkowska detailed the proposal in a press conference in Brussels.
