- Redwire wins DARPA contract for testing its proposed very low orbit satellite design
The key technology to be tested will be an “air-breathing” propulsion system that will take advantage of the thicker atmosphere at altitudes of 50 to 100 miles to provide the power to keep the satellite in orbit.
- Webb observes the most distant Type 1a supernova yet discovered
Type 1a supernovae were used to discover dark energy, based on the assumption that their brightness is always the same. Thus, the dimmer they are, the farther away they are. The data from this supernovae doesn’t break that assumption, according to the abstract, but it uncovered some pecularities that need explaining.
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.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Redwire = Low flying satellite or high flying plane? I’m inclined to the latter.
Yeah, once you throw “air-breathing” engines into the mix: aircraft.
I think the concept here is quite original. Launch a reconnaissance satellite into a very low orbit, where it is moving very fast but can obtain imagery daily of important targets. Then use a variation of air-breathing engines to keep it in orbit, for as long as necessary.
Those engines could even make it possible to shift the orbit radically, as needed.
This is a very far cry from a high-altitude reconnaissance plane, such as the U2.
