50 Years of Deep Space Exploration

50 years ago today, the Viking I mission made history. Launched on a Titan rocket, carrying the lander we built—Viking I became the first spacecraft to successfully land on Mars, opening the door to decades of planetary exploration. Since that milestone in 1975, NASA missions have mapped planets, explored asteroids and have helped reveal the mysteries of our solar system. From Viking’s pioneering landing to today’s most advanced spacecraft, this deep space heritage continues to inspire the next generation of discovery. We can't wait to see what the next 50 years of deep space exploration and planetary discoveries will reveal! Learn More: https://www.lockheedmartin.com/en-us/...
