Journey to Mars

Evaluate the engineering and human challenges of long-duration spaceflight to Mars — radiation exposure, muscle and bone loss, psychological isolation, communication delays — and assess the current state of the SETI programme: what methods are used, what has been detected so far, and what the Fermi Paradox is

Lesson

Set out your lesson

Evaluate Mars mission choices and distinguish an unconfirmed search from evidence that life is absent.

Before teaching

Use this short check, then start teaching.

Activity

Explain one space exploration milestone and why interplanetary travel is not like a short flight on Earth. Revisit the hard space-history prerequisite if needed.

If Not Ready

Pause and explicitly teach or revisit the named hard prerequisite; do not treat its allocation or authored status as learner readiness.

Printer, credit, and teaching notes

About 25 minutes. Paper or screen cards only. No health simulation, isolation exercise or personal decision to travel is required. Read Show together, then set it aside for the unaided first explanation; T2 intentionally supplies its own evidence snapshot.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

No medical risk calculation or mission safety certification.
A retrieved SETI FAQ provides a dated source snapshot only; this learner task remains hypothetical and does not assess the current detection record.
These bounded source-based examples and task opportunities do not establish learner mastery or general scientific performance.

Use the supplied paper cases only unless the optional paper prototype test is explicitly chosen. Do not handle electrical chargers, heat materials, mix chemicals, approach floodwater or volcanoes, or disturb animals. For the optional prototype, an adult checks a clear tabletop; use only paper and a blunt pencil, keep paper away from faces, and stop if the setup feels unsafe. Missing equipment, discomfort or no test means not performed: leave observations blank. No personal health, disaster or family experience is required.

Retain your actual plan and observations on paper between steps. If not performed, leave results blank. Record response mode and assistance; do not infer mastery.

Check understanding

Identifies and explains at least three major challenges of a Mars mission: radiation (no magnetosphere), bone/muscle loss from low gravity, psychological isolation, and delayed communications
Describes how SETI searches for intelligent life (radio signals, laser pulses, technosignatures) and explains why the lack of detection so far is not proof of absence
States the Fermi Paradox ('Where is everybody?') and discusses two contrasting proposed resolutions

“If your child was asked whether they'd volunteer for a 3-year mission to Mars, could they describe at least three serious scientific or engineering challenges that would need to be solved first — and explain why the 20-minute communication delay alone changes almost everything about how the mission would operate?”
