Genesis cover

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


Mars helicopter completes first test flight

The small helicopter that will fly autonomously as part of the Mars 2020 rover mission has successfully completed its first test flights here on Earth.

“We only required a 2-inch (5-centimeter) hover to obtain all the data sets needed to confirm that our Mars helicopter flies autonomously as designed in a thin Mars-like atmosphere; there was no need to go higher. It was a heck of a first flight,” [said Teddy Tzanetos, test conductor for the Mars Helicopter at JPL.]

The Mars Helicopter’s first flight was followed up by a second in the vacuum chamber the following day. Logging a grand total of one minute of flight time at an altitude of 2 inches (5 centimeters), more than 1,500 individual pieces of carbon fiber, flight-grade aluminum, silicon, copper, foil and foam have proven that they can work together as a cohesive unit.

This helicopter drone is a technology experiment, more focused on testing helicopter flying on Mars that doing science. If it proves to work, it will open up a whole new unmanned option for exploring the Martian surface. Imagine a helicopter that takes short hops from point to point. It will be able to reach locations a rover never could, and do it faster.

Readers!

 

Please consider supporting my work here at Behind the Black. Your support allows 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. 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. Only now does it appear that Washington might finally 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.

 

Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. 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.

    Rotors attached to a rover could be used to clean solar cells!

    I’ve always envisioned sweepers or dusters of some sort, but if there is enough atmosphere the be propelled by rotors, they could be used to clean surfaces too.

    If there’s enough atmosphere to support a helicopter, then there must be enough to transmit sound. Should be trivial to include a microphone so we can hear the “sounds of Mars”

    I got out my grandson’s toy helicopter. The lithium ion battery won’t hold a charge anymore, so I went to the hobby shop. They had one that would work but was slightly too large for a different model. It was only five bucks so I installed it thinking it will stay in the air longer but what actually happened is it could only rise a couple of inches… That’s it. The air from the rotors has a downdraft that will lift it up, when it has the floor to push against.
    If the craft with 10,000 RPM blades cannot lift itself more than a few inches in a six millibars of pressure (near vacuum) then it is not gonna work. (Except for removing dust)
