Question 1 of 5

1. Question

Consider the following statements about OSIRIS-APEX

Statement 1 – OSIRIS-APEX aims to observe the physical changes induced by Earth’s gravitational pull during Apophis’ flyby.

Statement 2 – Apophiss a stony “S-type” asteroid made of silicate material that is classified as a near-Earth asteroid, as opposed to a main-belt asteroid.

Which one of the following is correct in respect of the above statements?

a) Both Statement-I and Statement-II are correct and Statement II is the correct explanation for Statement-I
b) Both Statement-I and Statement-II are correct and Statement II is not the correct explanation for Statement-I
c) Statement-I is correct but statement II is incorrect
d) Statement -I is incorrect but Statement -II is correct

Correct

Solution (a)

Option a

Correct

OSIRIS-APEX

· It is a mission to study the physical changes to asteroid Apophis that will result from its rare close encounter with Earth in April 2029.

· That year, Apophis’ orbit will bring it within 20,000 miles (32,000 kilometers) of Earth’s surface — closer to Earth than our highest-altitude satellites.

· The mission aims to observe the physical changes induced by Earth’s gravitational pull during Apophis’ flyby.

· These changes could include alterations in the asteroid’s orbit, rotation speed, and surface features such as quakes or landslides.

· Additionally, the OSIRIS-APEX spacecraft will dip toward the surface of Apophis.

Key facts about Apophis

· It was discovered on June 19, 2004.

· It is a stony “S-type” asteroid made of silicate (or rocky) material and a mixture of metallic nickel and iron

· It is a remnant from the early formation of our solar system about 4.6 billion years ago.

· It originated in the main asteroid belt between Mars and Jupiter.

· Over millions of years, its orbit was changed primarily by the gravitational influence of large planets like Jupiter so that it now orbits the Sun closer to Earth.

· As a result, Apophis is classified as a near-Earth asteroid, as opposed to a main-belt asteroid.

Context: In an unprecedented extension of its celestial duties, the spacecraft that delivered asteroid samples from Bennu, OSIRIS-REx, has embarked on a new mission, and NASA has renamed it as OSIRIS-APEX.
