As an illustration, Webb and Hubble’s complementary protection via a number of wavelengths will assist reveal whether or not the collision threw off massive chunks of rock and particles or primarily tremendous dust. That’s not solely worthwhile for understanding the true nature of asteroids. It’s additionally important to understanding how massive and tightly sure the agglomerated materials inside asteroids is — as which will change the chances of success of a collision-based asteroid avoidance plan.
The James Webb House Telescope noticed DART’s collision with Dimorphos for a total of 5 hours, capturing 10 photos. In the meantime, Hubble captured 45 photos instantly earlier than and after the collision. Over the subsequent three weeks, Hubble will proceed to verify in on Dimorphos 10 extra occasions, monitoring how the ejecta clouds evolve and fade over time.
It might take weeks earlier than astronomers are capable of confirm whether or not DART’s impression modified the orbital interval of Dimorphos round Didymos, as meant. And it will likely be one other two years earlier than ESA launches the Hera mission to the system, which can perform an in depth post-impact evaluation of the binary asteroid.
Hera, like DART, is a mission supported by a world collaboration known as the Asteroid Impression and Deflection Evaluation, or AIDA. With these missions, scientists are working to develop and hone the strategies which will one day be mandatory to forestall a probably catastrophic asteroid strike on Earth.
In spite of everything, being ready is half the battle.
