The Hubble Telescope
Launched in 1990, Hubble has been visited by astronauts four times in order to make repairs and add new instruments. Each instrument that flies on Hubble has special features that let astronomers study the heavens in different ways. Hubble’s unique capabilities can also be partnered with other space observatories and those on the ground to enable scientists to explore the universe in ways that no single mission could ever accomplish alone.Source-Hubble Site.
Thank you David for the fascinating card and wonderful stamps.
2019 Stamp- The 50th Anniversary of the Apollo 11 Mission to the moon.
You're very welcome! This is the first time I've seen how one of my postcards arrived. I'm glad the postmark is light and the stamps are in good condition.
