>Block 2 includes design changes meant to solve these problems

What purpose does launching another Block 1 rocket serve? It doesn't seem as though the next ship on the line is capable of deploying a payload and trying to make the flight orbital would require another FAA review. I think there's a good chance that Elon just scraps it and moves onto Block 2.

>Using N2O4 Pentaborane propellent to establish a colony on Eris

Why hasn't anyone done this yet?

So are we finally all getting space catgirl gfs or is this fucking nothing again?

What are the differences in US space policy if we have Trump flavored potato vs Biden flavored potato?

What Elon said was that Starlink is now "Operating Cash Flow Positive". Anyone with an undergraduate level of finance knowledge knows what that means: Starlink is now scaled to pay ongoing costs but doesn't yet pay for the costs to launch or build the satelites. Not sure why WSJ is confused over this.

Interesting.
Damn I wish they'd explain these sorts of things in their stream instead of emoting and showing us pies.
They had people's attention for almost an hour and they said very little.

>Four earthly elements
>Fire
>Air
>Earth
>Water

None of those are elements, they are compounds and fire isn't even anything, it's just the energy released from the covalent bonds forming with the oxygen element.

I'm suprised that liquid ammonia has been ignored so long as a rocket propellant.

It has performance similar to methalox, but unlike the latter it produces no carbon in the combustion process.

It could also be a great alternative to jet fuel.

Why isn't ammonia (NH3) used more commonly as rocket fuel?

It can be stored at room temperature (under pressure), and contains no carbon so it doesn't produce soot when burned fuel rich.

Specifically, I'm pondering the use of either ammonox (ammonia and liquid oxygen), or ammonia burned with nitrogen dioxide (NO2) oxidizer.

how do I analyze my DNA, fellow /sci/entists? jewgle and jewtube keep giving me companies that would do it for me and I wanna do it myself. also price of equipment would be lovely.

somtimes when i go poopoo I hold my weewee than i stand up and weewee on my poopoo, this releases a very smelly smell Whut is happening here chemically? is the amonium in my weewee reacting with the poos somehow?

Totally doable but would not be worth the time and effort.

Honestly if you want to compete with a Starship clone a lot earlier than 2040 I wonder if it would be better to design a cheap, easy to build, and fully expendable version before sinking in development for reusability.
Even if Starship was fully expendable it would be a groundbreaking achievement.

Realistically the reason a lot of the time why it's hard to learn things in school is that you are limited by time. With enough time any topic or subject becomes attainable. You can do it, anon. Achieve enlightenment in the ways of Algebra.

>pour peroxide in waste bottle
>it starts fuming
>wasn't H2O2 waste
>just put the waste bottle back where it was

What does it mean if I'm good at numbers (can understand things very well when expressed solely in numbers) and awful in scientific abstracts? Are there any studies where I could fit in easily?

Has anyone here worked in the Pharma/Biotech industry? What is it like? Would you recommend it?

So what happens after they nail the 10km bellyflop? Do they do it again at 100km suborbital is Starship is able to get that high? Start testing the heat shields?

>Make an embryonic clone of yourself and implant it in a womans uterus (like what was done with Dolly the sheep)
>Suppress the hox-genes responsible for making the head segment in the developing embryo
>It never develops a head
>When it is birthed, hook it up to some nutrition via IV
>Administer the correct hormones as it grows and let it grow to 16-18 years old
And voila, you have a genetically identical organ bank that you can also transplant your head onto if you want a younger body.

Could this actually work in practice eventually?

Is the Soyuz craft REALLY that good or does the long use come from Roscosmos being virtually bankrupt and unable to innovate?
