Starting at the low, low price of $10,000, the joystick used to help guide Apollo 15's Lunar Module Falcon to the moon's surface in 1971 will be up for auction soon.

The Rotational Hand Controller has been in Commander Dave Scott's possession until now, Mashable reported.

"The lunar surface became visible during descent at about 7,000 feet altitude (LM 'pitchover') and based on the MCC input that we would land 3,000 feet south, I immediately began to move the target point north using the RHC to redesignate the LGC touchdown point," Scott described the importance of the RHC in a detailed letter quoted by RR Auction.

In the two-page letter of authenticity, Scott certifies the joystick as an important piece in the Apollo 15 journey and explains some of its various functions for the landing mission.

"This remarkable device, coupled with appropriate mode switching, provided the Commander and [crew] with 11 separate functions during four major phases of a lunar landing mission," he wrote.

The Lunar Module Falcon was around 3,000 feet south of its target when Scott had to direct it back to its designated landing spot, according to Mashable. The 1971 lunar landing marked the fourth U.S. manned mission to the moon.

While the joystick's auction price starts at $10,000, bidding could take it into the hundreds of thousands, Mashable reported. 

The upcoming space and aviation auction held by RR Auction will start May 15 and end on May 22.
