Mr Aldrin, 85, made the first lunar landing in 1969. He has tweeted his official travel voucher and customs forms for the moon rock he brought back.
The 'travel voucher' for his trip to space shows that Mr Aldrin claimed USD 33.31 for a journey from Houston, Texas, to the Moon and back, 'The Guardian' reported.
The voucher itemises each detail of Mr Aldrin's travel arrangements, with a 'government spacecraft' noted among government aircraft and automobiles used on the trip.
"Government meals and quarters furnished for all above dates," the voucher states.
It is believed that the expenses claimed reflect car travel between various airports on the trip.
Another tweet from Mr Aldrin showed that all the astronauts on Apollo 11 had to sign a customs form upon their return to Earth from the Moon.
The form, dated July 24, 1969, is signed by Neil Armstrong, who was the first man on the Moon; Mr Aldrin, who was Apollo 11's Lunar Module pilot, and Michael Collins.
In the form they declare that they had brought back moon rock and moon dust samples.
Mr Aldrin also tweeted a photo of the Apollo 11 astronauts in biological isolation garments, which they wore to avoid lunar dust from infecting people on Earth.
According to Mr Aldrin, the rags used to wipe the moon dust were dropped in the ocean.
