NASA’s Psyche mission speeds past Mars on its way to a metal asteroid

A NASA spacecraft called Psyche has made a close pass by Mars during its long trip through space. The flyby was not only dramatic to look at; it was also useful for the mission team. As the probe swept past the planet, Mars’ gravity helped change its path and give it extra speed.

The spacecraft is now heading toward 16 Psyche, a large asteroid in the asteroid belt between Mars and Jupiter. Scientists think this object may contain a lot of metal, which makes it very different from the rocky worlds we usually study. If that idea is correct, the mission could help researchers understand how planets formed in the early Solar System.

During the Mars encounter, the spacecraft also collected new images and measurements. Its instruments were checked and adjusted, and the team used the opportunity to confirm that the mission is still on track for its future arrival at the asteroid.

Context: In science news, reporters often describe space missions with active, exciting language, but the real work is careful navigation, testing, and data collection. A flyby can serve both as a scientific moment and as a practical step in a much longer journey.

Discussion questions

  1. ·Why might scientists be interested in an asteroid that could be rich in metal?
  2. ·What is the advantage of using a planet like Mars to help a spacecraft travel?
  3. ·Which part of this mission sounds more impressive to you: the images or the navigation? Why?

Teacher note: A short paraphrased news reading that explains Psyche’s Mars flyby, the gravity assist, and the mission’s route toward the metal asteroid. Includes brief context and discussion questions for B2 adults.

4. Listening

Your browser does not support audio playback.

Listen first

You will hear a short news summary about NASA’s Psyche mission. Listen for two things: why the spacecraft passed Mars and what it is heading toward next.

Answer the questions

  1. Why did the spacecraft fly close to Mars?
  2. What did the mission team gain from Mars during the flyby?
  3. What kind of object is Psyche travelling toward?
  4. Why is that destination unusual compared with most asteroids?
  5. What does the flyby help scientists test or check on the spacecraft?
  6. In your own words, what is the main idea of the report?
Teacher audio script
Presenter: NASA’s Psyche spacecraft has made an important pass by Mars on its long trip through space. The close approach was not just for the view. It also helped the mission team adjust the spacecraft’s path and gain extra speed. Scientists call this kind of boost a gravity assist.

Presenter: During the flyby, the probe collected new images and data from Mars while moving past the planet at very high speed. The team also used the opportunity to check how well the onboard sensors were working. That kind of testing is useful before a mission reaches its final destination.

Presenter: Psyche is now continuing toward an asteroid in the asteroid belt. What makes this target especially interesting is that it may be rich in metal rather than mostly rock or ice. Researchers hope the mission will reveal more about how objects like this formed in the early Solar System.

Presenter: If the flight plan stays on track, the spacecraft should arrive at the asteroid in 2029. For now, the Mars flyby has given the mission both scientific results and a helpful push on the way forward.

Teacher note: Listening task with a calm B2 news-style monologue about Psyche’s Mars flyby, its gravity assist, and the mission’s goal. Includes comprehension questions focused on the two main purposes of the flyby and the spacecraft’s destination.

5. Grammar

Passive Voice in Science News

Science news often focuses on what happened and what was discovered, not on who did the action. That is why reporters often use the passive voice.

Form

was / were + past participle

  • was + past participle → singular subject
  • were + past participle → plural subject

Basic pattern

  • Mars was photographed by the spacecraft.
  • The sensors were calibrated during the flyby.

Why reporters use the passive

The passive is common when:

  • the action is more important than the person or team
  • the doer is unknown, unimportant, or obvious
  • a text sounds more formal, objective, or news-like

Examples from a science-news style

  • The spacecraft was sent toward Mars in 2023.
  • A close flyby was completed on 15 May.
  • New images were captured during the approach.
  • The navigation system was tested during the encounter.
  • Mars was used as a gravity assist.
  • Several instruments were activated to collect data.
  • The mission was scheduled to reach the asteroid in 2029.
  • The spacecraft was boosted without using propellant.

Passive vs. active

  • Active: NASA engineers tested the sensors.

  • Passive: The sensors were tested.

  • Active: The spacecraft used Mars for a speed boost.

  • Passive: Mars was used for a speed boost.

Common mistakes

1) Using the wrong verb form

Incorrect: *The images were take. Correct: *The images were taken.

Incorrect: *The flyby was complete. Correct: *The flyby was completed.

2) Forgetting was/were

Incorrect: *The data collected during the pass. Correct: *The data was collected during the pass.

3) Using was with a plural subject

Incorrect: *The instruments was tested. Correct: *The instruments were tested.

4) Keeping the agent when it is not needed

Too wordy: *The images were captured by the spacecraft by NASA. Better: *The images were captured by the spacecraft.

Quick practice

Change these active sentences into passive ones:

  1. Scientists analyzed the data.
  2. The probe took the pictures.
  3. Engineers checked the trajectory.
  4. The mission team announced the results.

Remember

In news reports, the passive voice helps writers sound factual and focused on events. It is especially useful when describing missions, discoveries, and results.

Teacher note: Grammar focus on how science news uses passive voice to report actions, results, and discoveries. Includes clear rules, examples from the mission topic, and common mistakes for B2 adults.

6. Speaking

Class speaking activity — read, then practise aloud with your teacher or partner

Speaking: Why do missions like this matter?

1) Quick pair warm-up

L

Look at the mission idea

a spacecraft passes Mars, uses its gravity, and continues toward a metal-rich asteroid. In pairs, say one thing that surprises you about this mission.

2) Discussion prompts

Take turns speaking for 30–45 seconds each. Try to give a reason, not just a short answer.

  1. Why do you think scientists choose a flyby instead of stopping at every planet?
  2. What is the main advantage of using a gravity assist on a long journey?
  3. Which part of the mission sounds most impressive: the speed, the instruments, or the destination? Why?
  4. If a spacecraft carries a sensor that measures an object’s composition, what kind of information can scientists learn?
  5. Do you think a mission to an asteroid is more exciting than a mission to Mars itself? Explain your view.
  6. Some people say space missions are too expensive. Others say they lead to important discoveries. Which side do you agree with more?
  7. What practical benefits can space research bring to life on Earth, even when the mission is far away from daily life?
  8. Would you support a mission like this if you were a taxpayer? Why or why not?

3) Use these speaking starters

  • What surprised me most was…
  • I think scientists use flybys because…
  • A gravity assist is useful since…
  • The mission seems worth the cost if…
  • One scientific benefit could be…

4) Mini group challenge

In groups of three, agree on the best reason to continue this mission. Choose only one:

  • to save fuel and time
  • to study the asteroid’s makeup
  • to test new space technology
  • to inspire future exploration

Then give a 1-minute group report using at least two of these words: gravity assist, sensor, composition, asteroid.

5) Follow-up question

If you could ask the mission team one question, what would it be?

Teacher note: Guided speaking lesson on why scientists use flybys and what makes this Mars-to-asteroid mission worth discussing. Students practice giving opinions, using mission vocabulary, and comparing scientific value with cost.
