"NASA’s First
Planetary Defense
Technology
Demonstration to
Collide with Asteroid
in 2022"
by Justyna Surowiec
Structure is essential to the equation; in Didymos,
researchers aren’t sure whether DART will impact
an asteroid composed of solid rock, loose rubble or
something “softer,” more akin to sand. A softer
surface would absorb more of DART’s force and
may not be pushed as drastically as if DART hit a
harder surface.
Extensive modeling and simulation, part of a large
international campaign that started in 2014, is
being done in conjunction with Lawrence Livermore
National Laboratory and other members of the
investigation team to help researchers predict what
will happen to DART’s target after impact. They’ve
considered these various factors—along with the
added momentum from DART’s impact and the
resulting debris ejected from the crater it creates –
as they’ve run various simulations. These
simulations help the team shape its expectations
for impact.

A)
Use the passage from “NASA’s First Planetary
Defense Technology Demonstration to Collide
with Asteroid in 2022” and the video to answer
the question.
Behind the Spacecraft: NASA’s DART, The
Double Asteroid Redirection Test
Compared to the video, what is a limitation of
the article?
(1 point)
It lacks visuals that show the DART
simulations.
It lacks technical language to adequately
describe DART.
It lacks discussion of the potential
outcomes of DART.
It lacks explanation of the parties
involved in testing DART.

Answer 1

The limitation of the article compared to the video is:

It lacks visuals that show the DART simulations.

While the article provides a written explanation of the DART mission and the simulations being conducted, the video likely includes visual elements that can enhance understanding and illustrate the concepts being discussed.
