The secondary vehicle carried by the craft is a composite propelled rocket.
The only payload the rocket carries is a wireless ignition system and a cartridge
with flash powder. The rocket is spin stabilized by a rapidly rotating launch pad.
The alignment device for the rocket is also used to adjust the up/downlink antenna:
The rocket lifts off and then moves a distance of 500m along the surface of the
Moon. As the secondary vehicle must have the theoretical capability to move
five hundred (500) meters in a straight line displacement, a rocket is probably
the only vehicle which is able to move 500m approximately in a straight line
displacement on the Moon. Every ground vehicle moves more or less in a zigzag
course due to its ongoing and continuous course corrections. Attempting to win
the Range, Survival or Water Detection Bonus Prize is impractical. The
development and transportation costs alone far exceed the prize money.
The scientific benefit would be questionable because lunar excursions in excess
of 5km happened back in the 1970s as part of the Lunokhod program which
survived lunar days and nights, while evidence of water on the Moon was
discovered in 2009.
The rocket hits the ground and the ignited flash powder indicates the landing site:
The camera, mounted on the craft, verifies the journey’s length. The camera
makes also photographs to yield a full 360º view of the landing site, which
include the horizon and a vertical dimension of no less than 60º. The camera
can also capture a sufficient number of images and videos to meet the
requirements for imaging of the Logo Cluster. To capture the XPF Payload,
the payload specifications must be defined initially by their overall effect on the
whole construction of the craft.
The only Bonus Prize worth pursuing would be the Apollo Heritage site
— the Heritage Bonus Prize — but the risk is too high that a miscalculated
crash into this particular heritage site and others might occur, destroying
them and jeopardizing the mission in question in the process.
