To The Moon (Cyber, Medium, 299 pts)

Our faulty moon rover suddenly came back after a year of silence and reported an unusual telemetry. Seems that there is life on the planet!

Unfortunately, strange radio interference occured. Scientists proved that the error rate is less than 1 bit flip over 15 bytes of data. Luckily the rover software adds error correction codes. Try to restore a photo from the Moon: tothemoon.jpg.enc
