Mission Overview Studying Mars' Habitability, Seeking Signs of Past Microbial Life, Collecting and Caching Samples, and Preparing for Future Human Missions The Perseverance rover has four science objectives that support the Mars Exploration Program's science goals: All address key astrobiology questions related to the potential of Mars as a place for life. Mars 2020 Technology: Heritage and Innovation Technologies for Entry, Descent, and Landing The mission uses technological innovations already demonstrated successfully, especially for entry, descent, and landing (EDL).

Hangman You can set this page as a homework task for a group of students; doing so will give you a record of who has completed the task. Visit the teachers' section for more information. In the teacher's section you can also alter the sets of content, so that only some of the images appear. Alternatively, this link will start the game with the food content automatically selected and loaded. Use the teacher's section to create more links or embed code. This is version of the classic letter guessing game called Hangman. The letters are in 2 sets: vowels appear on the left and the consonants on the right. As with other games you can choose the content that you wish to use. There is also an option to review the vocabulary items. I hope you have fun playing this game and that you can learn or improve your English at the same time.
