This reading explores the real-world science behind the search for life on Mars and how decades of space missions have changed what scientists know about the Red Planet. It helps students understand why Mars is one of the most important places to search for life beyond Earth, how evidence of ancient water supports the idea that Mars may once have been habitable, and why scientists must be careful when interpreting possible signs of life. It also includes reading comprehension questions, extension questions, and a full answer key to help students build understanding, think more deeply, and connect the topic to real-world space exploration.

The article explains how missions such as Mariner, Viking, Spirit, Opportunity, Curiosity, Perseverance, and Mars orbiters have helped scientists study Mars over time. Students examine key concepts such as habitability, biosignatures, organic molecules, methane detection, rover instruments, Mars Sample Return, and future human missions, while also exploring why the search for life on Mars remains one of the biggest scientific questions of our time.

This resource covers the following topics:

✅ Grade 8 and Up Reading on the Search for Life on Mars: How scientists study Mars, what evidence they have found, and why the search for life continues.

✅ No-Prep, Editable Resource: Easy to assign as print or digital literacy practice.
