Upcoming missions in 2021

This year isn’t over yet. Three highlights in space exploration remains. The James Webb Space Telescope will supersede Hubble. Lucy will visit eight different asteroids during its 12 year mission through our solar system. Dart is a asteroid defense mission that can one day save our lives!

James Webb Space Telescope

The telescope, planned in the 90s and delayed for years, is now set to be launched December 18!

Proof of life?

Did the Viking landers find life on Mars? Hear it from Gil Levin himself. The creator of the Labeled Release experiment on the Viking landers.

Free Astronomy Books

Openstax Astronomy is free astronomy course ebook from Rice University. Download it from Openstax. Additional material is availble at this OER Commons hub.

Another free ebook is Introduction to Astronomy by Dr. Karina Kjær.

Astonomy Notes may look like a very early web page but it’s up to date and used by scholars.

NASA has bunch of free ebooks here. My favorite is the Beyond Earth: A Chronicle of Deep Space Exploration.
