Who should be left behind?

1. Exercise

2. Homework

Each person in the shuttle has been asked to write a letter for posterity (= those who come after, whoever that might be). The letters will be stored in a time capsule and the travelers hope that if life ever returns to Earth, these people will find the letters and, in time, be able to understand them.

The people writing the letters should:

1. ...introduce themselves briefly (no more than a paragraph)
2. ...share the thoughts, hopes and worries they have as they depart to start a new civilization 

• The letter should be about a page long (no more), written in Google Docs, normal font size, Times font. 
• Name the document "Time capsule letter" and put it in your English folder in Google Docs.
• Don't forget to write in the form of a proper letter, starting: "Dear posterity," and so on.
