Space: Viking 2 on Mars - letter, USA

This letter appeared on the successful landing of the "Viking 2" on Mars. The letter is postmarked with the special cancellation on the day of the landing, September 3, 1976 in the Kennedy Space Center. The memorial plate "VIKING USA MARS EXPLORATION" is stuck on the letter. The commemorative plaque depicts the "Viking Lander" shortly before touchdown on Mars.

In the "Viking" program, NASA sent two space probes (Viking 1 and 2) to Mars. The Viking 2 space probe launched on September 9, 1975 in Cape Canaveral for Mars. A year later, the spacecraft reached orbit. On September 3, 1976, the Viking 2 landed on a larger plain on the planet Mars. Through the missions, the scientists wanted to find out whether organic life exists on Mars. However, the space probe did not provide a clear result.
