Contact lost with Voyager 2, hopefully temporarily
New but planned commands to Voyager 2, presently flying beyond the solar system, caused the spacecraft to point its antenna incorrectly so that communications with Earth have been lost.
A series of planned commands sent to NASA’s Voyager 2 spacecraft on July 21 inadvertently caused the antenna to point 2 degrees away from Earth. As a result, Voyager 2 is currently unable to receive commands or transmit data back to Earth.
Voyager 2 is located almost 12.4 billion miles (19.9 billion kilometers) from Earth and this change has interrupted communication between Voyager 2 and the ground antennas of the Deep Space Network (DSN). Data being sent by the spacecraft is no longer reaching the DSN, and the spacecraft is not receiving commands from ground controllers.
The spacecraft is also programmed to periodically reset its orientation so that its antenna points to Earth, with the next reset scheduled for October 15th. Engineers hope that at that point contact will be recovered.
If not, this incident will mark the end of the mission, which launched in 1977 and has been functioning for 46 years as it has made close fly-bys of Jupiter, Saturn, Uranus, and Neptune, and then eventually entering interstellar space.
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

Experts and authorities are functionally fallible.
Sometimes they’re incompetent.
A couple generations have worked this mission.
The first lit the light.
What has followed is having problems with adequate stewardship.
You know it’s true.
V’Ger does what it’s told.
The Voyagers do what they’re told.
Contact with Viking 1 lander on Mars was lost in November 1982, for similar reasons: a software upload corrupted the antenna position. Much work was done attempting to recover comms, but did not succeed. RIP.
