It appears there were some communications and attitude control issues soon after Katalyst’s Link spacecraft was launched by Northrop Grumman’s Pegasus rocket, issues that the company’s engineers have now resolved as they prepare Link for its rescue mission to the Gehrels-Swift space telescope.
LINK launched July 3, completed its initial postlaunch sequence, and began system checkouts. After completing solar array deployment and establishing communications, Katalyst now has commissioned LINK’s power systems and avionics, as well as conducted propulsion system checkouts. This has involved firing the spacecraft’s xenon-fueled thrusters, which will be used to travel to Swift and slowly raise its orbital altitude over the course of several months.
The Katalyst team also quickly addressed early communications and attitude control issues seen during flight operations, including an issue with one of the spacecraft’s three reaction wheels. After identifying the cause, they implemented flight software patches and operational updates that restored reliable communications and stable attitude control.
The spacecraft’s check-out will continue for another two weeks or so, and then engineers will use its ion-engines to slowly raise its orbit to match Gehrels-Swift’s.
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
