Check the listing for details. Exploring Mars Stickers Pack - NASA Rovers & Ingenuity Helicopter. Condition: New. Listed at 4.50 USD. As one of the first exclusive items created to promote RocketSTEM's nonprofit mission, we're offering sets of these 3″ high-gloss vinyl stickers celebrating the history of NASA’s rovers – and now a helicopter – exploring the surface of Mars. Each of the four Mars Exploration stickers covers a generation of rovers on the Red Planet. From the Pathfinder lander and Sojourner rover in 1996, through the long-lasting Spirit and Opportunity rovers of the 2000s, and the Curiosity and Perseverance rovers of the last decade. We also salute the Ingenuity helicopter that continues to take to the sky on Mars as the first ever flying machine on another planet. The artist behind these exclusive stickers is one of RocketSTEM's own volunteers. We’ll also include our first RocketSTEM “Explore the universe” sticker and bookmark. You'll receive ONE SET of each sticker (5 stickers in all) plus a RocketSTEM bookmark with each purchase. Buy multiple sticker packs and save up to 25% on your order. 100% of the proceeds from the sale of these exclusive stickers benefit RocketSTEM, a nonprofit organization devoted to promoting STEM education and inspiring the next generation of explorers.
