Today sees the launch of Artemis, the continuation of manned flights to the moon, 5 decades after the Appolo missions. Arthmis, Apollo's twin in Greek mythology will today start a 42 day journey into space as a prelude to men landing back on the moon 2024. Although not standing quite as tall as Apollo it's quite a bit more powerful and has the ability to carry a huge payload to the moon. I'm assuming the lauch will be live on utube for those who are interested  |

Thanks Jeff, brings back great memories as a 13 year old staying up in the early hours to watch that first step on to the moon's surface.

Artemis update: NASA launch coverage delayed due to 2 outstanding issues. One engine is not cooling down to the right temperature, and there is an unexpected frost line at one of the rocket joints.
Other issues encountered were the weather with lightning risks, and a brief hydrogen leak that developed at the transition to fast fill. The storms dissipated and they conditioned the line to eliminate the leak. Tanking is at 97% currently.
The plan now is to force all the venting through the engine that is too warm (#3). That should cool it down.

Just for info, the launch window is between 13.30 and 15.30 BST today, the next avail day for launch if the issues aren't sorted is Friday.

Am I alone in being interested in any plane, but totally uninterested in space?

It seem not, a lot are not interested in space but love a plane..... Which is strange as Shuttles are even listed in some databases nowadays.
I guess it's like gliders and balloons as well though, some arnt interested in those either although the same people are avid plane spotters.

 Having been to the Houston Space Station and Cape Kennedy Jeff- I am interested- all be it not everyone's cup of tea- if men do go back to the moon it will hopefully bury the myth that it was a bit of a con, like Graham I remember watching them landing on the moon as a young boy, and looking up at it on a clear night with a full moon, thinking Wow!!! to think a man has been up to the moon and walked on the surface. My mate has an app which tracks the International Space Station and tells you when it will pass over our area's. Keep the reports coming mate- makes interesting reading. Happy days Bob

I take any manned aircraft. Be it a plane, helicopter, balloon, glider. I remember being fascinated by the Apollo moon landings at the turn of the 1960s / 70s decade. Looking forward to it happening again. I wonder if they will bring that golf ball back when an astronaut does again set foot on the lunar surface!

Sorry no update for Saturdays planned launch, a wedding anniversary and Popham put paid to that.. Lol
Anyway, it was Canx again!
From the NASA Artemis conference yesterday:
1. There was an inadvertent pressure spike during LH2 chilldown, that raised the line pressure from 20 to 60 psi, due to an error in valve control. It's suspected this might have dislodged or damaged the soft goods in the umbilical seal, but that is not confirmed.
2. The magnitude of the leak was very large, exceeding the allowable limit by several times. Much larger than previously seen, and indicative of soft seal damage, rather than thermal equilibrium.
3. No possibility of launch this period. The FTS restrictions will require a rollback to the VAB, unless an exception is granted, which is doubtful. They may attempt to replace the seal at the pad, and then test under cryo conditions, before rolling back.
4. They are working the fault tree to be sure they understand what happened, and that will take some time. So no prediction for next launch attempt. Could be in either of the next two launch windows, in late September and middle October.
