News ESA's Future: The News and Updates Thread

And in other news: The service module for EM-1 has left Germany for the USA:

The aircraft is over Greenland right now and will land in Portsmouth soon, after a refueling stop in Hamburg (after only 17 minutes of flight from Bremen airport).

The aircraft is RA-82068.

And before you are confused, its that Portsmouth:

Its a bit more complicated, this article is essentially talking about my paid job: Computer aided engineering.



A part of it describes PDM, product data management, especially keeping data consistent.



Virtual A.I.T touches what is called "virtual validation" outside ESA: Making sure something can actually be build outside the computer. It is still a very complicated thing and only done in bigger companies - and current technology results sometimes in assembly sequences, that require a complicated 4D trajectory for getting a part into the assembly.



But: Assembly, Integration and Testing means more than that, VV only covers assembly. Integration requires fit testing, accessibility and RF compliance for launch vehicles and transport containers. Testing already making sure it works in space before it gets build.



This now means really something new: Virtual AIT requires a FDMU, a functional digital mockup. While DMUs are commonplace today, FDMU are cutting edge technology. A FDMU would be easy if it is just about testing if the solar arrays can deploy, but really complicated if you want to predict how it reacts to solar wind.



A simple FDMU is already way more complicated than the FEM models used in crash simulations - there one special model only needs to work for a few simulated milliseconds and when exceeding a load in simulation #10, simulation #11 will continue at this point lacking a part of the model and get optimized for this calculation.

Europe’s Galileo satellite navigation system – already serving users globally – has now provided a historic service to the physics community worldwide, enabling the most accurate measurement ever made of how shifts in gravity alter the passing of time, a key element of Einstein’s Theory of General Relativity.
Two European fundamental physics teams working in parallel have independently achieved about a fivefold improvement in measuring accuracy of the gravity-driven time dilation effect known as ‘gravitational redshift’.

ESA is looking forward to another interesting year in 2019.
ESA astronaut Luca Parmitano will return to the International Space Station, in Science Cheops will look at exoplanets, while the EDRS-C satellite will start the era of super-fast data relay on orbit.
In Kourou preparation will go full speed for Vega-C, a more powerful version of ESA’s light weight launcher, also paving the way for future Ariane 6.
And in November in Spain at 'Space 19+', the Council at Ministerial level, ESA will propose to its Member States a bold vision for a strong Europe in Space.

7 January 2019
When ESA’s planned Hera mission journeys to its target binary asteroid system, it will not be alone. The spacecraft will carry two tiny CubeSats for deployment around – and eventual landing on – the Didymos asteroids. Each companion spacecraft will be small enough to fit inside a briefcase, as compared to the desk-sized Hera.

Hera – named after the Greek goddess of marriage – is a candidate ESA mission that will be humankind’s first probe to rendezvous with a binary asteroid system, a little understood class making up around 15% of all known asteroids.

Due to launch in 2023, Hera would travel to a binary asteroid system – the Didymos pair of near-Earth asteroids. The 780 m-diameter mountain-sized main body is orbited by a 160 m moon, informally called ‘Didymoon’, about the same size as the Great Pyramid of Giza.
