T - 16 hours until Antares - Cygnus flies again for the first time since the accident in 2014

What are the chances of a successful launch, /sci/?

I'd wager 40% at best.

RD-181s should be totally fine for the first stage, and the CASTOR 2nd stage is just a modified version of an existing CASTOR and those have been flying for ages.

The problem with the accident was the explosion-happy NK-33s which enjoy burning through themselves. I'm surprised the Russians are bothering with them on Soyuz-2, but those are being replaced with the RD-193 (basically the same as the RD-181).

areojet had to buy back those rebuilt nk33s after the explosion - what do they do with them?

>> No.8416923

>>8416881
Probably put them right back in storage where they got them, waiting for the next sucker to come along and buy some cheap looking engines.

It's free rocket engines.

So maybe they're from the 1960s. So maybe there's nobody around who worked on them. So maybe they're from a rocket that blew up every time it tried to launch.

They were literally sitting in a barn. Complete rocket engines. Big, powerful, high-efficiency ones. Like, 60 of them.

That makes people's fingers itch.

In retrospect, understanding that THESE were the engines Kistler wanted to use for their *reusable* rocket, it's no wonder that they went out of business before building anything.

>>8417143
I suppose that makes sense, and they are just interim engines until they get the RD-193s going. Would be a shame to have a Soyuz failure because of them though.

From an evolutionary standpoint, it makes sense that astronauts, some of the most physically fit and capable specimens of our species, would be attractive. Because over the course of their bloodline, that attractiveness would have given them access to the choiciest of mates.
