This is a translation of a very large piece of material by Tim Dodd, better known as Everyday Astronaut, about CAS and its necessity. Let's go!
SpaceX's upcoming mega-rocket, Starship, is quickly coming to life before our eyes. Starship will be the largest and most powerful rocket ever flown. It is capable of delivering 100 people to the surface of Mars and, just as important, back. Moreover, it will be a fully reusable rocket. The holy grail of space flight, something that could completely change the rules of the game, ushering in a new era of human access to space.
BUT! As excited as I am about Starship, it seems that something is missing - the flight abort system. How can Starship be safe enough for humans if they cannot escape from the ship during an emergency? An emergency interrupt system or an emergency rescue system can save the crew from a doomed ship, saving their lives in the event of a disaster. They are almost universally recognized as a necessity when there are people on board.
So, wouldn't it be a good idea to have some kind of removable cockpit with its own thrusters and landing system? Or, literally, an enlarged Crew Dragon with its own interrupt system at the top for the first few manned missions until childhood illnesses are eliminated? In the end, Space Shuttle, which tragically lost two crews, also lacked SAS. Will the same story be repeated with Starship? Can we really trust Starship?
This is one of those topics that I get asked over and over again, and for good reason!
And this topic became even more relevant the moment we witnessed the destruction of the Starship MK1 prototype, SN3 / 4/8/9 during testing. What if there were people on board, why isn't SpaceX thinking about installing SAS?
As you may know, I've already talked a lot about flight abort systems in an article explaining why both SpaceX's Crew Dragon and Boeing's Starliner chose liquid-fueled CAS as opposed to the more traditional system. - towers with solid propellant engines at the top.
Now, if you didn't notice when you clicked on this article, this is another rather long article on this topic again. As you probably know, I do not like to be fluent in topics, I like to delve into data and history to find answers. We're going to dive into a lot of small details, charts and data, and MORE charts and MORE data.
We'll look at rocket certifications, rocket engine reliability, the risks and benefits of ship design, and even look at the entire history of human space flight and find out how many times SAS actually saved the lives of those on board.
By the end of this article, it will not be just my opinion on whether Starship without CAC is a good idea or not, it will be more of an analytical summary.
So, SAS. The idea is simple, rockets are fickle beasts. They use the best engineering solutions, they must withstand extremely intense loads, temperatures and environmental conditions, and also be as light as possible. Since there are literally millions of moving parts, to be honest, they work wonderfully at all.
So when someone gets on a machine that is a giant nozzle bomb that has millions of parts to work properly in order NOT to fail, it is usually considered a good idea to have a backup plan if anything something doesn't go as planned.
The term of imprisonment for insulting a veteran of the Great Patriotic War (WWII) can be up to five years, and the fine - up to 5 million rubles, said Deputy Speaker of the State Duma Irina Yarovaya on the air of Channel One.
“We responded with an amendment, which henceforth establishes liability up to 5 years in prison and up to 5 million [rubles] fines for actions that will defile memory, offend veterans,” Yarovaya said (quoted by TASS). She noted that the punishment is provided for those who insulted both living veterans and the dead.
Earlier, a group of State Duma deputies prepared amendments for the second reading to the bill on the protection of historical memory, implying tougher liability for libel and insult to WWII veterans.
Changes must apply to Art. 354. Criminal Code (rehabilitation of Nazism), as well as Art. 13. 5 Administrative Code (abuse of freedom of the media). The bill on the protection of historical memory, which is being amended, was unanimously adopted by the State Duma in the first reading on February 10.
Don't worry. Everything goes according to plan.
They do not want to imprison themselves or to fine themselves under this amendment?
So. And can I not as a veteran, but as a person offend? Just wondering.
here we are not talking about veterans at all, but about another opportunity to just jail a person.
If before I didn't give a damn about Navalny, now I hate him. How many times have they said: don't tell them.

Alexey Navalny will personally attend the court hearing in the case of libel against a veteran, in which he has the status of an accused. This was reported to RIA Novosti by the press service of the Babushkinsky court in Moscow.
