An aerospace agency is designing a constellation of climate-monitoring satellites that capture high-resolution multi-spectral images of the Earth's surface. The agency decides to compress all data files on board before transmitting them to ground stations.

Identify two benefits of compressing these files.

A: It encrypts the data packets, preventing unauthorized interception of sensitive scientific data. B: It reduces the transmission time and communication bandwidth required to downlink the files to ground stations. C: It decreases the physical storage capacity required on the satellite's onboard storage drive. D: It automatically corrects transmission bit-flips caused by cosmic radiation. E: It decreases the electrical power consumption of the satellite's onboard CPU.
