Such nightmare scenarios are exactly what NASA engineers are developing sophisticated software technology to avoid. NASA is currently testing one of the more important components of such software — the algorithms that incorporate the spacecraft's trajectory, speed and landing information to guide a ship to a safe arrival. The latest algorithm, known as Fuel Optimal Large Divert Guidance algorithm (G-FOLD) is being flight-tested in conjunction with Masten Space Systems at the Mojave Air and Space Port in California."
