A lovely cross made up of Space Shuttles and Apollo Capsules:

Four figures of Space Shuttles make up body of our cross, while four Apollo Lunar Modules radiate out from the center. The space vehicles all point to their ultimate destination – the golden brilliance of the stars and the cosmos itself!

The elements of our Astronauts Cross come together to honor all those who have contributed to Humankind’s exploration of space. We honor the brave men and women of Mercury, Gemini, Apollo, Skylab and the Shuttle programs as well as the early programs of the NACA that took us through the sound barrier and to the outer regions of the atmosphere. We honor all those involved in current space research and engineering such as those involved in the Constellation program which will establish the first human colony on the moon. And most especially, we commemorate our three Astronauts who died in the fire onboard Apollo1, the crews of the Space Shuttles Challenger (STS-51L) and Columbia (STS-107), as well as all the unheralded test pilots, the cosmonauts of SOYUZ 1 and SOYUZ 11, and all the others who have given the ultimate sacrifice to advance science and our quest to reach out beyond the boundaries of Mother Earth.

Part of the purchase price goes to the Astronauts Scholarship Foundation, which is pretty cool.
