Turn your students into science detectives with this NO PREP, engaging, real-world investigation focused on how spacecraft get power in space. In this case file activity, students analyze spacecraft energy evidence, examine solar panels and batteries, evaluate deep-space power systems, investigate power management, rank possible causes, and build a scientific case to solve the mystery of how spacecraft keep working far from Earth.

Instead of passively learning about spacecraft energy systems, students actively investigate, analyze patterns, and reason through the evidence to uncover how solar panels, batteries, radioisotope power systems, and power management all work together to keep spacecraft operating. This activity makes a high-interest space science topic interactive, engaging, and easy to understand while strengthening critical thinking and literacy skills.

✅ NO PREP, no formatting, no issues. Simply download and go. Includes all instructions, answer key, rubric, and background reading students need to solve the case. This mystery is included inside my Space and Space Exploration Mystery Activity Bundle.

10-Part Activity Breakdown

Part 1 – Mission Briefing:

Students are introduced to a case involving spacecraft systems and the question of how spacecraft get power and keep operating in space.

Part 2 – Background Reading:

Students build foundational knowledge about solar panels, batteries, backup systems, radioisotope power, and why different missions use different energy sources.

Part 3 – Evidence Log:

Students examine 10 detailed evidence cards related to solar panel electricity, shadow problems, battery backup, deep-space distance, radioisotope power, power for onboard systems, solar panel angle, limited power choices, mission design matching, and successful power system patterns.

Part 4 – Suspect Ranking:

Students rank possible explanations (solar panels convert sunlight into electricity, batteries store energy for times without sunlight, some deep-space spacecraft use radioisotope power systems, power management systems distribute electricity where it is needed, and the incorrect idea that spacecraft can run in space without a power source once launched) and justify their reasoning using scientific evidence.

Part 5 – Pathway Tracking:

Students trace how an energy source powers a spacecraft through changing mission conditions and keeps systems working.

Part 6 – Impact Analysis:

Students analyze how spacecraft generate energy, why storage systems are needed, and how power generation, storage, and management all affect mission success.

Part 7 – The Big Question:

Students explain how spacecraft get power in space and how different power systems support different missions.

Part 8 – CER Writing:

Students construct a scientific argument using Claim–Evidence–Reasoning.

Part 9 – Solutions & Action Plan:

Students propose ways to learn more about spacecraft energy systems, model power generation or storage in class, and improve future spacecraft power systems.

Part 10 – Reflection:

Students reflect on what surprised them most about spacecraft power and how energy systems support missions in space.

What Students Will Learn

• How many spacecraft get electrical power in space
• How solar panels convert sunlight into electricity
