NASA’s two ESCAPADE spacecraft each pulled off a powered Earth flyby, using Earth’s gravity plus a sustained engine burn to fling themselves toward Mars. They’re on track to arrive in September 2027.
- It’s the first time NASA has used a powered Earth flyby to head to Mars, and they did it twice in two days.
- They launched Nov. 13, 2025, when Mars was on the far side of the Sun, then parked in a kidney-bean-shaped loiter orbit near Lagrange point 2 until the planets lined up.
- Mission designer Jeff Parker says this approach lets future missions launch almost any time instead of waiting for the usual Mars windows.
My take
Breaking free of the every-26-months launch window is a big deal. Clever orbital mechanics beats waiting. Nice work to the twins and the small team behind them.
God Bless, and Happy hacking!
