Explosion of the turbopump of engine № 8 of the N-1 № 5L 0.22 seconds before launch during the second flight test.
The detonation was so powerful that it tore out part of the tail section, damaged engines № 7 and 9, and also the cable network

Update on the HLS provider timelines from NASA
Short Overview:
Still targeting early 2028 for Artemis 4 and late 2028 for Artemis 5.
Starship cargo lander expected in 2032 and Mk2 cargo lander in 2033.
NASA provided an image of the CONOPS for Artemis 3 which is currently targeting NET Q3 2027.
Starship uncrewed landing demo still targeting NET Q4 2027. Blue Origin uncrewed Mk2 landing demo NET Q1 2028.
Starship Milestones:
First cape flight in Q4 2026 (currently NET Dec 10th). Completed HLS "Cabin 1" in Q4 2026 (ground testing cabin). This will have operations testing in Q1 2027 and airlock demonstrations in Q2.
Prop demo in Q1 2027, first launch from LC-37 also in 2027 - I personally believe 37a will be ready in Q2 or Q3.
Tank presurizations upgraded in Q2/Q3.
The first uncrewed landing demo tanker launch in Q3 with the landing demo in Q4.
Blue Origin Milestones:
New Glenn return to flight Q4 2026. First Blue Moon Mk1 landing in Q1 2027. Second Mk1 landing in Q4 2027 with the viper rover. Third Mk1 landing in Q1 2028 with an LTV (Lunar Terrain Vehicle) for Artemis 4.

The first Starship to return to its launch site, Ship 40's journey took it across air, space, and sea. Now that it is vertical alongside three other Starships in a Megabay at Starbase, it will provide first-of-its-kind data on a flown Starship heatshield, Raptor engines, avionics, and more.
