The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. It also simulates space flight in Earth's orbit.
FlightGear's flight dynamics engine (JSBSim) is used in a 2015 NASA benchmark to judge new simulation code to the standards of the space industry. FlightGear is used professionally for research and development, as well as non-professionally.

As of 2020 there are over 700 aircraft and spacecraft projects available with 1 click download and install from the sim's launcher, more are available at 3rd party hangars and github repositories for different craft projects.
FlightGear 2020.3.8 and later has automatically downloaded 3d models of buildings, roads, cities etc. , based on Open StreetMap (OSM) data and automatic generation, for the whole world.
Platforms: Windows, macOS, Linux, Raspberry Pi, other OSes

I mean, there are plenty of good deep sky images out there. Try looking at the New General Catalogue (NGC) objects for something that strikes your fancy. Alternatively, you could cruise around in Space Engine and bookmark an interesting galaxy to get screenshots from multiple angles, which is what I usually do. (SE is available on Steam for a reasonable price.). Source: 10 months ago
Computer says yes: https://gravitysimulator.org/ https://spaceengine.org/ Once the mass, velocity, heading of an object is known it becomes easier to track and fine tune parameters meaning time of intersect with earth can be calculated which gives orientation of planet and entry attitude. An exact street addres | sub metre grid reference is a big ask, but the "line of breakup" arcing across a narrow slice of the... - Source: Hacker News / 10 months ago

This is a bit of a tall order. There are none that I know of; most folks I know who do galaxy maps either make them by hand with their digital paint tools of choice, or utilize the procedurally-generated ones from Space Engine. Up until recently SE had a free (old) version available on the site; you should still be able to find a mirror of it somewhere but I don't know of one personally. Otherwise, SE is available...

Numbers as overwhelming as these are meaningless to our little minds. Then, do yourself a favor. Download Space Engine and see for yourself what it's like to visually behold the mindblowing immensity we are talking about. Now, take into account Multiverses, and consider the possibility that all those Universes may be fractal-like with n-infinite dimensions. Contemplate that we probably know absolutely nothing...
