I don't have the link but on Friday, NASA released the report on the
Antares failure at Wallops. Basically failed turbopump in one engine
that caused it to explode and rest exploded. Range safety was activated
to help reduce damage, but still destroyed the launch pad.



That's what you get when you use 40+ year old Russian engines that no
one in the US truly understands. This was truly penny wise, but pound
foolish.

Next one will b on Delta 4 and after that, they plan on using newer
generation of russian engines.

Atlas V. Delta IV costs too damn much and is being phased out by ULA.
