A Lucy solar panel on Lucy fails to latch properly after deployment
Текст новости:
Engineers at Lockheed Martin (the prime contractor) and Northrop Grumann (which built the panels) are now troubleshooting an issue with one of the solar panels on the asteroid probe Lucy, which failed to latch properly after deployment. The NASA graphic to the right illustrates this issue, though the graphic might not accurately portray the exact circumstance at Lucy. To get more solar power, Lucy’s panels are larger, and thus were designed to unfurl like a fan rather than the more commonly used accordion design. One panel has not completed that unfurling. NASA’s announcement tries to minimize the issue but this quote from the link makes it clear that this could be a very big problem. It’s not yet clear whether the array in question is, in fact, fully deployed but not latched in place or whether it did not reach full deployment and is not generating the same amount of power as its counterpart. It’s also not yet clear whether Lucy can safely fire its maneuvering thrusters with an unlatched array. Share

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
