Engineers recharge Ingenuity’s batteries on its way to Mars
Engineers have successfully completed their first in-flight maintenance recharge of the batteries on Perseverance’s small test helicopter Ingenuity.
NASA’s Ingenuity Mars Helicopter received a checkout and recharge of its power system on Friday, Aug. 7, one week into its near seven-month journey to Mars with the Perseverance rover. This marks the first time the helicopter has been powered up and its batteries have been charged in the space environment.
During the eight-hour operation, the performance of the rotorcraft’s six lithium-ion batteries was analyzed as the team brought their charge level up to 35%. The project has determined a low charge state is optimal for battery health during the cruise to Mars.
They plan to do these partial recharges about once every two weeks during the trip to Mars to keep the battery charged the optimal amount.
About a month after Perseverance has landed in February 2020, it will find a large flat area to deploy Ingenuity, then move away. The helicopter will then begin a 30 day test program to see if it will be able to fly in the very thin Martian atmosphere, only about 1% as thick as Earth’s.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

This is a fun easy to understand 16-minute video about the Mars helicopter:

It will be interesting seeing it fly. With the highest Martian atmospheric density being equal to 115k feet on earth this will be quite an engineering accomplishment.
I heard Jim Green say in an interview today/yesterday that the little chopper won’t fly higher than 5 feet.
That’s the hight at which an elk could gnaw on its blades. Testing for alien life, NASA style.
