NASA's New Mars Plan: Smaller Missions, More Frequent

NASA has a fresh plan for exploring Mars. They want to send smaller missions more often, with a focus on key scientific questions. These missions could cost between $100 million and $300 million each. The idea is to gather important information before humans ever set foot on the planet. The plan has three main goals. The first is to find out if there's ever been life on Mars. The second is to get ready for human missions by figuring out what we need to know before we go. The third is to learn more about Mars as a planet, comparing it to Earth.

NASA wants to use commercial partnerships and international help to make these missions happen. They also want to update the old infrastructure on Mars, like the communication relays and the Mars Reconnaissance Orbiter. The plan doesn't include any specific missions or budget details. It's more like a menu of options that NASA can choose from based on what's possible with their budget.
