As of October 2026, which spacecraft are flying away from Earth, like Artemis II?
Research question: As of October 2026, which spacecraft are currently leaving Earth orbit (for example, Artemis II's lunar mission status and recent interplanetary probe launches), and how are their trajectories planned to account for Earth's rotation and orbital motion around the Sun?
The records show that Artemis II launched on April 1, 2026, and completed its translunar injection burn on April 2, 2026 12. It splashed down in the Pacific Ocean off San Diego on April 10, 2026, so the records do not show it still underway in October 2026 4. The provided facts do not identify any other spacecraft currently leaving Earth orbit, so the question about present-day departures is only partly answered 14. On trajectory design, the records note that a projectile's Earth-rotation deflection depends on firing direction 5, and a 2025 study simulates periodic online replanning of a low-thrust heliocentric trajectory to keep end-state errors small 6. A 2010 analysis notes that the initial guess for Trans-Earth Injection targeting ignores third-body gravitational effects from Earth and the Sun 7, and that the Earth-entry flight path angle must fall within a corridor that can be under one degree wide 8. The newest fact dates to April 2026, about six months before October 2026 4.
