Arianespace successfully completes first Ariane 5 launch in almost a year
Arianespace today successfully completed its first Ariane 5 launch since August 2020, placing in orbit two commercial communications satellites.
The long gap in launches occurred because of a vibration issue discovered during that August 2020 launch durng the release of the rocket’s two fairing halves.
Engineers introduced modifications to the Ariane 5’s payload fairing, or nose cone, to reduce vibrations imparted on the satellites during separation of the shroud, which protects payloads during the first few minutes of flight through the atmosphere. Ground teams will analyze data from the rocket to make sure the changes reduced the vibrations.
Another launch is scheduled for September, followed next by the launch of the James Webb Space Telescope in either November or December. The results from today’s launch as well as the one in September will determine if the Webb launch will go forward on time.
These issues with Ariane 5, delays imposed by the company in fear of the Wuhan flu, and other launch problems with Arianespace’s Vega rocket, has meant that this is only its second launch in 2021, a pace that is below its pace for most of the last decade. Whether the company can recover and pick up the pace before the end of the year will depend on what they learn during today’s launch.
With only two launches total, Europe’s Arianespace remains off the leader board in the 2021 launch race:
24 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab
The U.S. lead over China in the national rankings remains 30 to 24.
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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

Things that make you go ‘hmmm’
A private company (SpaceX), has 10x the launches of a continental (Continental?), governmental, organization. Huh.
