NASA: NanoSail-D2's mission a success

The video tutorial covers the launch of a spacecraft on November 19, 2000, as a payload on NASA's FAST AT satellite. Initially, the spacecraft failed to jettison but unexpectedly ejected on January 17, deploying its sails two days later. The tutorial explains how solar sails use sunlight for propulsion, providing slow but constant acceleration that can lead to high speeds. The mission concluded with the spacecraft burning upon reentry on September 17.

When was the spacecraft launched as a payload on NASA's FAST satellite?

• November 19th, 2000

• January 17th, 2001

• September 17th, 2000

• December 25th, 2000

What was the initial issue faced by the spacecraft after its launch?

How do solar sails propel a spacecraft?

• By using gravitational slingshots

• By using sunlight to create a slow but constant acceleration

• By using chemical propulsion

• By using solar panels to generate electricity

What happens to the spacecraft after completing its mission?

• It burns upon reentry

• It is retrieved by another spacecraft

• It continues to orbit indefinitely

• It returns to Earth safely

On what date did the spacecraft burn upon reentry?

• January 17th

• December 25th

• November 19th

• September 17th
