How Will We Know if NASA’s DART Mission Successfully Changed an Asteroid’s Orbit?

TL;DR

NASA's DART mission aims to deflect an asteroid and Lowell Observatory is one of the observatories studying the impact's effects.

Transcript

This is Lowell Observatory. Lowell is one of many observatories around the world that will be observing the DART impact, NASA's first ever planetary defense test mission to see how much a spacecraft impact can deflect an asteroid in its orbit. This is where Pluto was discovered. And we are still doing research in all areas of astronomy today. So le... Read More

Questions & Answers

Q: What is the purpose of NASA's DART mission?

The DART mission aims to test the deflection capabilities of a spacecraft impact on an asteroid, providing insights for future planetary defense strategies.

Q: Why is Lowell Observatory involved in the DART mission?

Lowell Observatory has a history of astronomical research, including the discovery of Pluto. They will contribute data from the Lowell Discovery Telescope to study the effects of DART's impact.

Q: What is special about the binary asteroid Didymos and Dimorphos?

Didymos is a larger asteroid with Dimorphos orbiting around it. The DART spacecraft will intentionally impact Dimorphos to observe changes in its orbit caused by the impact.

Q: How will observations be conducted after the impact?

Observers will analyze images of Didymos to measure changes in brightness, indicating when Dimorphos passes in front of or behind it, allowing for the determination of the orbit period of the satellite.

Summary & Key Takeaways

• Lowell Observatory, known for discovering Pluto, is participating in NASA's DART mission to deflect an asteroid.

• The Lowell Discovery Telescope, located in a forest with dark skies, will collect data on the binary asteroid Didymos and its satellite Dimorphos.

• Observations will involve measuring changes in Didymos' brightness as Dimorphos passes in front of and behind it.
