An external view of Europe’s largest vacuum chamber, the Large Space Simulator, which subjects entire satellites to space-like conditions ahead of launch. This 15 m-high and 10 m-diameter chamber is cavernous enough to accommodate an upended double decker bus.
Satellites are lowered down through a top hatch. Once the top and side hatches are sealed, high-performance pumps create a vacuum a billion times lower than standard sea level atmosphere, held for weeks at a time during test runs.
A 121-segment mirror array reflects simulated sunlight into the chamber, at the same time as the internal walls are pumped full of –190°C liquid nitrogen, together recreating the extreme thermal conditions prevailing in orbit.
Embedded sensors and measurement devices check whether a mission’s thermal engineers have done their job well, and if the test satellite maintains an acceptable internal temperature range without buckling or other unwanted temperature-driven effects.
The simulator is an essential part of ESA’s Test Centre in the Netherlands, the largest facility of its kind in Europe, providing a complete suite of equipment for all aspects of satellite testing under a single roof.

This screenshot is a part of the tutorial. The machine--a Cessna 152--is "flying" somewhere over Arizona, I think.
I had been a Flight Simulator (FS) user since the early mid-Eighties. However, about 15 years ago, I stopped using FS. The latest version has reignited interest, particularly with high details, both in the aeroplane as well as the landscape and airports.
A rear view of ESA’s single most powerful solar simulator.
An array of 19 xenon lamp modules, each consuming 20 kW, cast a concentrated beam of artificial sunlight into Europe’s largest vacuum chamber, the Large Space Simulator.
Part of ESA’s ESTEC Test Centre in Noordwijk, the Netherlands, the 15 m-high 10 m-diameter chamber subjects satellites to simulated space conditions for weeks at a time: deep vacuum, unfiltered sunlight and the chill of space recreated by liquid nitrogen being pumped around the walls.
Just 12 out of 19 lamps are sufficient to recreate the sunlight encountered at Earth orbit. To simulate environments closer to the Sun, the 20 kW lamps can be swapped for 32 kW versions, or the mirror array used to reflect sunlight within the chamber can be adjusted for a more focused light beam.

Sometimes looking back is a good thing. The DPU has a great view as the sun dropped behind the mountains colouring the clouds.

After our tour of Daytona Speedway, Jessica, Jackson, and Joshua all drove this simulator in the NASCAR museum. The instructor said that women made better drivers than men.
After an absence of about 5 months, the locomotive simulator 'CN 9633' (previously for sale, current status unknown) is back at Exporail, here on a flat car which is coupled to VIA 6309.
Just a short video of me trying out the Origami Simulator on my Nanachi crease pattern. Works surprisingly well! I think this tool could be useful when testing out new complex CPs, to see how the collapsing will roughly look like.
While Mr. Savelsberg has been building vehicles from TV series, I have been secretly building aircraft from computer games. While perhaps less obvious, by now I have built all six planes that can be flown in my favorite flight simulator game. Can you guess which game it is?
Meanwhile it is solved:

The six planes that can be flown in the game are: P-51, FW-190, MiG-15, F-86, MiG-21, F-4.
Ice Lakes is an ice lake fishing game simulator.

Game Description and Comments:
No matter your location, Ice Lakes stands as one of the best ways to experience fishing without leaving your house. This holds especially true for me and ice fishing since I have never seen a frozen lake...

The Mercedes-Benz Actros is a series of heavy-duty trucks, first introduced in 1996, and currently in its fourth generation. It is normally used for long-distance haulage, heavy duty distribution haulage and construction haulage. It is available in weights starting at 18 tonnes and is powered by an inline-6 diesel engine with turbocharger and intercooler. Daimler Trucks/Lorries launched the version II of the Actros in 2002, and the version III in 2007. The fourth generation of the Actros, named officially the New Actros launched in July 2011
The fourth version offers several engine options in either Euro-5 or Euro-6. In Euro-6, inline-six engines are used in both series: OM471 with a 12,8-litre engine range power output of 310 to 390 kW (422 to 530 PS) and OM473 with a 15.6-litre engine range power output of 380 to 460 kW (517 to 625 PS), with a fuel rail pressure of 280 MPa (2,800 bar) and a double overhead camshaft (DOHC) with 24 valves in compliant models.

When it's cold outside and I have nothing to do. We have a new place down the street from my place, that has golf simulators we can rent. This is the first time I've been there, but it's fun, and pretty accurate!.
