- Gilmour Space once again delays first launch of its Eris rocket
The new target launch date is July 16th.
- On this day in 1985 Europe’s Giotto probe was launched to visit Halley’s Comet
The fly-by occurred on year later.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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

Some stories today
“Record breaking material emits infrared light better than it absorbs it without breaking the laws of physics.”
“Students develop rocket engine powered by beeswax.”
and-
“Space-based experiments show wax-filled heat sinks keep electronics cooler for longer.”
Two other stories
“Predictive model uses pressure data to help reduce water leaks in pipes” (Box-Jenkins methodology).
–and
Research on ice-forming compound could improve pipeline safety, carbon capture, and storage” (clathrate hydrates).
Both of these may be of use to Starship–the first in leak finding.
Now pipeline explosions with clathrate hydrates may seem of little import to SS/SH because that’s supposed to be pure methane.
But how pure is “pure?”
Could gas-gas engines open themselves up to another failure mode not found outside methalox rockets?
How much water vapor might be in those methane tanks?
