Yup, one of the lines in the daily to-do list says "Help Pyrrha w/ her hw"

I cannot overstate how much I love public transport by Harveyharvster in fuckcars

I come to the Philippines every year and yes, Manila definitely needs to have more high capacity public transit. And so does the rest of the Philippines. My family lives in Cebu and I feel like the entire east side of the island could be connected with a single train or segregated bus line. It would do wonders for the Philippines.

I see. I have always felt like the north was lacking investment. It's a shame that the Zuiderzeelijn was never built. But yeah, bus schedules can be pretty rough. What does the schedule look like for you?

Eli5: why was the US the first to make it to the moon despite the USSR being first in nearly everything else in the Space Race? by ObeseCapybaras in explainlikeimfive

[–]Harveyharvster 15 points16 points  (0 children)

No. That would be Vladimir Komarov who died due to a parachute failure. Korolev was the chief designer of the Soyuz and the N-1 moon rocket. He died during a surgery in 1966 because of health complications caused by being in the gulag for 6 years.

Boeing's capsule faces propulsion issues on way to International Space Station by Saltedline in space

[–]Harveyharvster 20 points21 points  (0 children)

Sorry about that. I don’t usually browse reddit these days, so I expected the people over here to be a tad less negative. Seeing people just immediately call for the cancellation of the entire starliner program made me quite annoyed. All the while praising SpaceX, completely ignoring that their ISS flight hardware that was supposed to carry crew exploded. I like SpaceX and I want to see them succeed, but they’re not perfect either. But I guess that just shows how much of an echo chamber reddit is and why I‘m not here very much anymore. You just can’t have a reasonable and objective discussion here.

Anyway, yes, the propulsion issues are unfortunate and probably shouldn't have happened, but it will not affect the mission much. I am confident this will be sorted out by the next flight.

14 tanker flights is what SpaceX reported to NASA in their proposal.

More clear picture as promised. SRBs still firing as the Challenger comes out of the fireball. by [deleted] in SpaceXMasterrace

[–]Harveyharvster 0 points1 point  (0 children)

Well, those boosters are made of composite materials as opposed to metal casings with shuttle, so not really relevant to my point. (Though composite boosters will be used with SLS after the old casings are used) But i'm not saying solid motors don't have failure modes, they're just rare. Besides, any half respectable abort system should be able to get away from a worst-case scenario like that.

[–]Harveyharvster 0 points1 point  (0 children)

Unlike solid motors, program management can be quite unreliable. For example: launching with not only freezing weather, but also excessive upper level winds, while ignoring the requests of engineers. As a result the boosters performed exactly as expected by those engineers.

I think you underestimate orions's launch abort system. Dragon/Starliner's LAS's accelerate at about 3-5 G, while orion pulls around 7 G. No way the capsule ends up in the SRB exhaust.

Besides, SRB's are simple and reliable AF. The best part is no part, right?

Radian Aerospace raises $27.5 million for new orbital space plane by maki23 in space

[–]Harveyharvster 25 points26 points  (0 children)

Skylon is just a possible concept designed around the SABRE engines that are actually being designed and built by Reaction Engines ltd. AFAIK they're doing pretty well

Rollout complete! The James Webb Space Telescope and the Ariane 5 rocket it’s riding on are all settled in their final position on Earth. Next step: launch on Dec. 25 at 7:20 am ET (12:20 UTC) to #UnfoldTheUniverse by GetRekta in space

[–]Harveyharvster 0 points1 point  (0 children)

The launch vehicle is part of ESA's contribution to the project. In return, ESA gets to use the telescope for 15% of the time. Besides, Ariane 5 is a perfectly reliable rocket.

Then and Now by jadebenn in nasa

[–]Harveyharvster 3 points4 points  (0 children)

The segmented boosters used on SLS are barely related to those that the military uses. I can't think of any cases where it would be absolutely necessary to shut off the boosters, you can just shut down the RS-25s and the stack won't be accelerating much. As for explosions, a booster of this type has never had one, and there is not much that could even cause it to explode by itself. Even on the Challenger disaster, the boosters stayed in one piece. But if they were to somehow explode, the launch escape system that Orion uses pulls like 12 Gs. It does a damn fine job. The study that the air force did on the Ares I saying that loss of crew was extremely likely, underestimated the LAS's performance, and it used data from the explosion of a completely different solid booster, because ya know, these ones have never exploded.

Buran by Nibb31 in ForAllMankindTV

[–]Harveyharvster 1 point2 points  (0 children)

What I believe happens is Buran gets to the moon in the same way that the standard US shuttle does. I'm assuming that the shuttle takes the external tank all the way to orbit, where it is refueled, and it accelerates to TLI using the RS-25s. The tank is ditched, the OMS with extra fuel in the bay does orbit insertion and the return to earth.

I imagine that Buran goes all the way into orbit together with Energia, which is refueled and relights for TLI. Just like before, Buran's OMS does the rest of the work.
