Dragonfly Completes an Integrated Flight Rehearsal
How to use these two pages
Give learners the student worksheet. It contains the story and questions, without the answers. Keep this guide for yourself. Use it to lead the activity and explain the answers afterwards.
Student worksheetA simple 15–20-minute lesson
- Before reading · 2 minutes
Show the title. Ask: “What do you think this story is about?”
- Read and answer · 8–10 minutes
Give out the student worksheet. Learners read for the main idea, then reread to answer the 2 questions. They can compare answers with a partner.
- Discuss and write · 5–8 minutes
Check the answers below together. Ask learners to point to the clue in the story, then finish with the open question.
Adjust the support: Let learners use word help or Level 1 if needed. For a challenge, compare the wording in another level. This activity is not a proficiency test.
Answers to the 2 questions
The question numbers match the student worksheet. Each answer includes a reason and the clue learners can find in the story.
What does this milestone actually demonstrate?
Correct answer: A — An integrated landing simulation
Why: The test combined software and electronics.
Clue in the story: A Johns Hopkins APL testbed combined Dragonfly's software and flight-like electronics for an autonomous landing simulation, NASA reported.
Which claim would overstate the launch timing?
Correct answer: B — Launch is guaranteed in 2028
Why: No earlier than is not a guarantee.
Clue in the story: The milestone does not represent a physical flight on Titan. Further testing remains before a launch no earlier than 2028 and anticipated arrival in 2034.
The open question: accept different answers
Ask learners: Describe the evidence without confusing rehearsal and deployment.
One possible answer: The rehearsal tested systems on Earth; Titan operations remain in the future.
This is an example, not the only correct answer. Look for a relevant idea, a reason and the learner’s own words. Learners can answer aloud or write one or two sentences.
