First segments of Extremely Large Telescope have shipped to Chile
After 20 years of development, the first eighteen segments of Europe’s Extremely Large Telescope (ELT) have now shipped to Chile, with another 780 more segments to go.
The assembly of the telescope’s massive mirrors will take place over the next 4 years. This week, the first segments of what will be the main mirror – called ‘M1’ – arrived in Chile.
Once complete in 2028, these segments will create a primary mirror 40 meters across, about 131 feet, four times larger than the 10.4 meter Gran Telescopio in the Canary Islands, presently the largest telescope in operation.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

A professional soccer pitch is 115 by 74 yards (105 by 68 meters). An American football field measures 100 yards long between the goal lines by 53.3 yards wide (91.44 by 48.8 meters). In each dimension, a pitch or a field is larger than the primary mirror of the ELT.
Sorry to be pedantic :-)
Steve White: You are of course correct. I was thinking feet when it is yards on an American football field. I have deleted the football field reference. Thanks.
Man it would be so awesome to work with this.
It will be amazing, until the next large telescope gets put into orbit.
Remember, Hubble is only 2.4 meters.
While I am thrilled by programs like the M1, I agree with other opinions expressed here that the future of astronomy is exo-atmo.
