========== CENTENNIAL CHALLENGES BREAKING NEWS ==========

Three Centennial Challenges Competitions at the X PRIZE Cup

Centennial Challenges begins an especially exciting time as three
competitions--Beam Power, Lunar Lander and Tether Challenges--are held
at the X PRIZE Cup, October 20-21, Las Cruces, New Mexico. The X PRIZE
Cup is a space exposition which features the competitions, rocket
launches, rocket planes, static engine test firings, fly-overs, exhibits
and other events.

The Beam Power and Tether Challenges are being held for the second time
and are offering larger purses--$200,000 for each competition. To win, a
team's climber must ascend a 50-meter ribbon at a minimum speed of 1
meter per second. The competition has been made more difficult this
year--each climber's mass is now constrained to 25 kilograms and teams
must provide their own beam power source.

The Lunar Lander Challenge offers a total purse of $2,000,000-an amount
that is a milestone for the program. The Challenge is divided into two
levels. To win at either level, a rocket-propelled vehicle and payload
must take-off vertically, fly for a period of time, and then land
vertically on a target that is a fixed distance from the take-off point.
After remaining at this location for a period of time, the vehicle must
take-off, fly for a period of time, and land again on its original
launch pad. The primary difference between the two levels will be in the
time of flight, the surface terrain at the landing sites, and the
corresponding degree of difficulty presented for precision landing and
servicing of the vehicles.
