Opis: Solar System bodies make deep space exploration more fuel efficient! Todayâs video shows the Psyche spacecraft gaining speed and changing its trajectory with minimal fuel spent due to a gravity assist from Mars in May 2026. Mars has an average orbital speed of almost 87,000 km/h (54,000 mph) around the Sun. Its orbital motion and its gravity allowed Mars to pull Psyche along with it, increasing the spacecraftâs speed. Gravity assists have been used since 1959âs Luna 3 mission to allow for spacecraft (the Voyagers, Cassini) to reach farther than they could with fuel alone. This assist helped the Psyche spacecraft on its journey to the Psyche asteroid, which it will reach in 2029. While passing Mars, the spacecraft tested instruments that will analyze the asteroidâs composition and magnetic field. This is the first mission to an asteroid thought to be largely made of metal, an essential building block for planets, rather than rock or ice.
