OSIRIS-REx makes last course correction before releasing asteroid sample return capsule
OSIRIS-REx’s engineers on September 17, 2023 successfully completed the last course correction necessary before releasing the sample return capsule carrying about nine ounces of material from the asteroid Bennu, set to land in Utah on September 24th.
The spacecraft briefly fired its thrusters Sunday to change its velocity by 7 inches per minute (3 millimeters per second) relative to Earth. This final correction maneuver moved the sample capsule’s predicted landing location east by nearly 8 miles, or 12.5 kilometers, to the center of its predetermined landing zone inside a 36-mile by 8.5-mile (58-kilometer by 14-kilometer) area on the Defense Department’s Utah Test and Training Range.
Details on that landing can be found here. The capsule will be coming in at speeds comparable to that of an Apollo capsule, returning from the Moon, and will use the same maneuvers and parachutes to slow its speed to only eleven miles per hour at landing. Four helicopters will than rush to recover the capsule as quickly as possible to reduce the chance the sample will be contaminated by the Earth’s environment.
OSIRIS-Rex (renamed OSIRIS-Apophis Explorer or OSIRIS-APEX) will meanwhile fire its engines and head towards the potentially dangerous asteroid Apophis, with a rendezvous scheduled in 2029.
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 lesson for Varda, perhaps? Make sure whatever you want to return to Earth cannot stay in orbit.
I think I have seen this movie. It does not end well.
