The SpaceStation.jpg contains the encrypted flag in the file flag.enc. The flag is encrypted using openssl and the AES algorithm. The iv and key used for the openssl encryption command are opcodes in an executable named Bangalore that is also hidden in SpaceStation.jpg.
You will need to know just a little bit about crypto, executable file formats and assembler to solve this challenge... objdump is your friend :-)
Needed info is provided in the embedded readme file.
