Flight Of Nova is a "hard science" simulation focused on Newtonian mechanics and atmospheric flight around the full-scale planet NVA-31.

An open-world mode where you receive missions via your cockpit's monitor and explore the vast 12,700 km diameter planet at your own pace. Version 0.52 Context

The game features realistic gravitation, orbital mechanics, and atmospheric drag based on vessel shape and air density.

Unlike combat-heavy sims, this is primarily a transport and search-and-rescue simulator. You pilot multiple craft types to deliver cargo, rendezvous with orbital stations, and survive high-heat re-entry to land at surface outposts. Modes:

A series of structured missions in specific regions or orbital stations.
