Astra reveals vague details about its next larger rocket
Capitalism in space: In a public event in California yesterday Chris Kemp, CEO of the rocket startup Astra, revealed some vague details about the company’s new larger rocket, dubbed Rocket 4.0.
The vehicle will be able to place up to 300 kilograms into low Earth orbit and 200 kilograms into sun-synchronous orbit at a “base price” of $3.95 million. By contrast, Astra’s current Rocket 3.3 vehicle can accommodate a small fraction of that payload, having to date launched only a few cubesats at a time.
…The biggest change in the rocket is its first stage propulsion. While Rocket 3.3 uses five of Astra’s Delphin engines, generating a combined 35,000 pounds-force of thrust, Rocket 4.0 will use two larger engines that produce a combined 70,000 pounds-force of thrust.
Kemp’s presentation however did not reveal whether Astra is building it or whether the company is buying it from someone else. He did say the company does not plan to attempt ot reuse any portion of Rocket 4.0, saying that the economics did not work for Astra.
His presentation also suggested a first launch for late this year, using a mission control made up of only two people, what he called “a pilot and a co-pilot.”
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.

“using a mission control made up of only two people, what he called “a pilot and a co-pilot.” ”
This is an interesting point, why the heck do launch operators have banks and banks of people sitting in front of monitors? Are we seeing a costly tradition established 70 or so years back that has no reasonable purpose just rolling on and on? Realistically if something goes wrong with the rocket those people are just spectators.
ICBM class though. Keep a lid on it guys. Don’t want it TOO easy.
