Astroscale launches satellite that grabs and burns space junk

The video discusses the issue of space debris, highlighting the dangers posed by thousands of small objects orbiting Earth. It introduces the Elsa D satellite, designed to tackle space junk using magnets. The satellite consists of two parts: a chaser and a target, which will be launched together. Once in orbit, they will separate to perform various capture experiments, with increasing complexity. The ultimate goal is for the chaser to capture the target and safely deorbit, burning up in the atmosphere.

What is the primary concern associated with space debris in Earth's orbit?

• It causes interference with satellite communications.

• It poses a threat to current and future spacecraft.

• It increases Earth's gravitational pull.

• It can block sunlight from reaching Earth.

What is the name of the test satellite designed to collect space junk?

• Apollo 11

• Voyager 1

• Elsa D

• Hubble

What are the two components of the Elsa D satellite?

• A chaser and a target

• A sensor and a detector

• A transmitter and a collector

• A launcher and a receiver

How does the chaser unit of Elsa D capture the target?

• With a magnetic docking plate

• Through a laser beam

• By deploying a net

• Using a robotic arm

What is the final step in the operation of the Elsa D satellite?

• The chaser sends data back to Earth.

• The chaser returns to Earth with the target.

• The chaser releases the target into a higher orbit.

• The chaser and target burn up in the atmosphere.
