XB-70A Posted April 15, 2018 Share Posted April 15, 2018 Here is my small contribution to the "live" community. The pictures were took from a parking spot of Playalinda Beach, about 10 km/6 miles from the LC-41. Spoiler Link to comment Share on other sites More sharing options...
Blasty McBlastblast Posted April 15, 2018 Share Posted April 15, 2018 @XB-70A those are amazing pics!! I'm feeling pretty jealous or your launch-side seats about now! *reaches for tin-foil hat* but did we just watch the launch of a bunch of experimental hunter-killer satellites? While viewing the launch broadcast we get to hear about some of the experimental payloads that will be tested: armour local area sensing for on-orbit anomaly detection mycroft sub-satellite which is highly manoeuvrable + lots of dV advanced guidance navigation & control for use in geosynchronous orbit It seems that these tests will lead to craft that can dodge incoming kinetic attacks, and perhaps become kinetic weapons themselves?

Scotius Posted April 15, 2018 Share Posted April 15, 2018 (edited) I, on the other hand, wonder if any of payloads experiments you mentioned been previously in space... on one of the secret X - 37b missions, perhaps?

Thank you Blasty! Yesterday was a bit particular, I had to work on my business, and end a studies report, or go to Atlas V... hum... priority to Atlas V! I don't know how long I will stay in this sector, so it is better to enjoy it before having to move away from this beautiful chance. Link to comment Share on other sites More sharing options...

Scotius Posted April 21, 2018 Share Posted April 21, 2018 If Vulcan went active like... two years ago, or even last year it would be a significant event. But now? Times are a-changing Reusability is the name of the game, and cost reduction plays bigger and bigger role as new launch providers enter the market with their own medium-to-heavy launchers. I'm very curious in which direction things will go in the next decade Link to comment Share on other sites More sharing options...
tater Posted April 21, 2018 Author Share Posted April 21, 2018 Yeah, the biggest issue is that Vulcan will be a reset on reliability for ULA. Right now they're the "when it absolutely, positively needs to get to space" provider. If all goes well, SpaceX will pass them in the next few years assuming their launch cadence only improves a little. Vulcan will have no history at all, which seems like it eliminates a huge selling point of ULA right now. Link to comment Share on other sites More sharing options...

XB-70A Posted April 22, 2018 Share Posted April 22, 2018 Hey everyone, I have a question about Atlas V's 5.4 meters fairings but haven't found any answer to it. During the launch of GOES-S during last March it was possible to distinguish a "tube" on the fairing. Here are two pictures of the launch, with the perpendicular "tube" (at the right of the fairing): Would anyone know what it is (could it be a separation device)? Thanks Link to comment Share on other sites More sharing options...
Canopus Posted April 22, 2018 Share Posted April 22, 2018 (edited) @XB-70A Maybe electric supply for the payload while on the pad?

Scotius Posted April 25, 2018 Share Posted April 25, 2018 Yeah, hilarious. I've counted at least 7 events during which entire process is at risk, simply due to hardware failure. Personally i'm not surprised ULA stopped talking about this plan. Link to comment Share on other sites More sharing options...

Lets just hope they don't drop the thing in acid seawater too much. Otherwise it would just be an expensive trick. Link to comment Share on other sites More sharing options...
