Comment A beast of a rocket (Score 1) 45

124.4 meters (408.1 feet) tall, 9 meters wide, 5,500 metric tons at launch with a TWR of 1.6. Should leap off the pad and hit max Q in 45 seconds. These engines are grossly overpowered for the launch mass, which implies another stretch. And they're a work of art.

I have to go see one of these launches one day.

And they're not done. Raptor 4 is in the works. They really are going to Mars. The long dry spell of "boldly go" is coming to an end.

Comment Mars is still the goal (Score 1) 73

The Moon is target practice. We need to get away from innovative bespoke engineering, into industrial mass production with continuous improvement. To do that we need to fly often. Mars just doesn't have the launch window availability. The biggest part of the challenge is that we were born in the bottom of a deep well. To toss enough stuff out of the well for a long journey is critical. Boosters that reliably fly on time often and cheaply enough to get ships and fuel out of the well. Ships that carry fuel into orbit and return over and over since the vast majority of the material we need to send out of the well isn't payloads or ships, it's fuel. Kilotons of fuel. Once the factories and processes are set up for that going far beyond the Moon is fairly easy. But with a narrow opportunity every two years that's not going to happen in a human lifespan. It's not enough refinement cycles per year.

I see this accelerating the Mars objective, not deferring it.

Submission + - Ryugu asteroid samples contain all DNA and RNA building blocks

symbolset writes: More and more science is pushing back the Drake equation, reducing the parameters necessary for life to form. From the discovery that organic molecules are formed in the little red dot protogalaxies at the edge of our visible universe to AI models that identify a self replicating RNA molecule in only 45 nucleotides. Now comes Toshiki Koga et al with a study published in the journal Nature Astronomy reported on by phys.org finding all the nucleobases of RNA and DNA in pristine samples collected from the asteroid Ryugu. The bases being uracil adenine, guanine, cytosine and thymine. Ammonia was also found.

The universe it seems is made of soup.
