The 10c stamps was from 1975 Space Issue depicting Mariner 10,Venus and Mercury.

Mariner 10 was a robotic space probe and it explored Venus and Mercury in 1974,and Mercury again in Mar.1975.

During its flyby of Venus, Mariner 10 discovered evidence of rotating clouds and a very weak magnetic field.Mariner 10 flew past Mercury three times in total.It revealed a more or less moon-like surface. It thus contributed enormously to our understanding of the planet, whose surface had not been successfully resolved through telescopic observation.

Presently, Mariner 10 is still orbiting the sun, although its on-board electronics have probably been damaged by the sun's radiation.

The 79c stamp was from 2009 Scenic American Landscapes Series,featuring a sandstone formation in the slickrock area of the Zion National Park,Utah.

Located at the junction of the Colorado Plateau, Great Basin, and Mojave Desert regions, the park's unique geography and variety of life zones allow for unusual plant and animal diversity. Numerous plant species as well as 289 species of birds, 75 mammals (including 19 species of bat), and 32 reptiles inhabit the park's four life zones: desert, riparian, woodland, and coniferous forest. Common plant species include cottonwood, Cactus, Datura, Juniper, Pine, Boxelder, Sagebrush, yucca , and various willows.
