kerbiloid Posted March 24 Share Posted March 24 (edited) The first ever flown spaceship with a real flight attendant onboard https://en.wikipedia.org/wiki/Marina_Vasilevskaya [snip] P.S. Her backup crewwoman was Anastasia Lenkova, a kid surgeon. Probably was not selected due to absence of kids onboard, so in this case they would have to send a midwife first.

Snark Posted March 24 Share Posted March 24 Some content has been redacted and/or removed due to off-topic digressions. Folks, the topic of this thread is Russian launches and missions. Kindly leave the "my rocket is better than your rocket" posturing at the door. It's off topic, it solves nothing, and it just makes the thread less useful and interesting to all concerned. Thank you for your understanding. Quote Link to comment Share on other sites More sharing options...

DDE Posted April 6 Share Posted April 6 (edited) Found some TEM Nuklon functional testing hardware now on display at VDNKh. Wide angle Spoiler The cube on the left is the non-nuclear support systems module, ostensibly a used testbed Written markings may be just artifacts of disassembly and shipping And it's a bit banged up The telescoping "keel" And, of course, a rough model of the reactor The stenciling from Keldysh helpfully indicates those are rough dummies Thus, we discover that the reactor features four sets of a cooling heat exchanger and a recuperator, all designated S5.159.1012-0 Also, a TEM model. Yes, it's conspicuously different from the rest of the hardware Spoiler I get the impression that these nozzles mounted next to the reactor are the revised propulsion system - those mechanically driven rotor plasma thrusters we came across some years go. We definitely know such a version of the TEM was considered, and this could be the jumping-off point for a drastically different TEM design. The reactor section seems reversed compared to how it'd normally be, and that was also a feature of the alternative renders. @nyrath, as per usual, I have a nuclear rocket to share.
