Redwire developing a satellite designed to fly in extremely low orbits
The orbital manufacturing company Redwire is now developing a satellite, dubbed SabreSat, to fly for long periods in extremely low orbits where the atmosphere would normally cause the orbit to quickly decay.
SabreSat, Redwire Space’s satellite for very low Earth orbit, looks more like a dart than a traditional spacecraft. “As you think about aerodynamics, you want the dart to be skinny and long, not stubby and fat,” Spence Wise, Redwire senior vice president for missions and platforms, told SpaceNews.
Redwire is designing SabreSat for government intelligence, surveillance and reconnaissance missions.
The satellite would fly in orbits from 55 to 200 miles altitude. By flying so low it will get far better images and ground data than spacecraft in higher orbits. It will also be less vulnerable to attack compared to high altitude aerial reconnaissance balloons or airplanes.
Its dart-like shape will meanwhile reduce friction so that less fuel will be required to maintain its orbit.
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.
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.

… and should be cheap to launch. Won’t even need a Falcon 9 for that.
55 miles…imagine a strike weapon stationed at that altitude. Like a tungsten rod, which would have an incredible sectional density and very low drag.
David Ross, there’s little energy difference between a 200×200 and 200×55 mile orbit, in fact it’ll require more energy to maintain such a orbit for very long compared to the energy to launch to a circular 200 mile orbit.
