Software glitch blamed for Japanese moon lander crash.

Ispace's Japanese Moon Lander, Hakuto-R Mission 1, crashed due to a software glitch that caused it to misjudge its altitude during landing. The software guiding the descent lost track of the lander's altitude when it passed over the rim of a crater on the moon's surface that was about two miles higher than the surrounding terrain. The failure pointed to shortcomings in Ispace's testing of the spacecraft's landing software, which was developed by Draper Laboratory of Cambridge, Mass. The company's next two missions remain largely unchanged, involving an almost identical lander next year and a larger spacecraft in 2025 to the far side of the moon.
