Capturing the real-world thrill and challenges of planetary exploration, XTRONAUT™: The Game of Solar System Exploration gives 2 – 4 players ages 7 and up the chance to develop space missions and explore the solar system. The game is based on real planetary missions and rocket science. It also contains elements of politics and strategy that are inspired by the real-life situations that space missions face. How do you complete your space mission? Each player selects a Mission Card from the deck. This card determines the player's mission – the mission destination, type of spacecraft needed, the amount of Delta-V needed to achieve the mission, the potential to obtain gravity assists, and the points earned for completing the mission. Delta-V stands for change in velocity, and as applied to space missions and this game, it means the change in velocity necessary for a spacecraft to complete a selected mission. Game play is straightforward. On their turn each player draws a playing card, plays up to three Action Cards, trades with other players, and places components on their game board. The Action Cards add real-life issues to the game that space missions often encounter - project cancellations, audits, government shutdowns, and other exciting twists and turns. To complete a mission you must populate your game board with the right combination of cards for mission success. Each player needs to collect the Playing Cards that give them the right spacecraft, first and second stage rockets, and matching fairings. Gravity assist and solid rocket booster cards are available to provide additional Delta-V if needed to complete the assigned mission. Once the mission is complete, the player earns the points for the mission, which varies based on the size of the spacecraft and the target, and starts work on their next mission. The first player to score 10 points wins.
