Boeing Starliner delayed. They should delay again.

A contractor for Nasa urged the space agency to conduct more safety checks before the highly-anticipated first launch of its Starliner rocket – which is set to take off as soon as next week – “before something catastrophic happens”.

It was supposed to launch last week, but someone spotted a valve problem — *minutes* before the countdown procedure was about to start.

They’d better check for door plugs while they’re at it.

Boeing does not give a rat’s ass about whoever uses their products. They‘re only interest in paying dividends to stockholders. And of course paying the CEO’s ridiculously high salary.

NASA is trusting the future of space travel to people like Musk and companies like Boeing. Using taxpayer money to reward greed and incompetence.

We can do better than this.

Newly discovered cosmic megastructure challenges theories of the universe

The so-called Big Ring has a diameter of about 1.3bn light years, making it among the largest structures ever observed. At more than 9bn light years from Earth, it is too faint to see directly, but its diameter on the night sky would be equivalent to 15 full moons.

This is important because it contradicts the so-called “cosmological principle” that everything in the universe is basically evenly distributed.

Just thinking about it, though, it makes little sense to assume that galaxies are all evenly spaced. Assuming the Big Bang was a single point should not imply even spacing of anything.

FWIW the “Big Ring” is evidently more a corkscrew shape, directly aimed at us. Evidence of “cosmic strings”? Maybe.

This is not as interesting as technology that will allow us to build hotels and colonies at LaGrange points or communities on Mars, but it’s still interesting. Sorta. Maybe?

Chandraan-3 rover finds…sulfur on the Moon?

India’s Moon rover is making tracks…

One main reason for landing at the Moon’s South Pole is that the presence of water would help us build permanent settlements…

This region on the moon is an attractive place for humans to build a lasting presence due to the fact that water ice is located underfoot. Future moon-dwellers can potentially tap into that water for consumption, or even to create rocket propellant, instead of depending on water shipped from Earth.

Another reason has now been found…iron, manganese, aluminum, titanium…and “surprisingly” sulfur. Why should they be surprised? It’s already been established that the Moon has ice, and sulfur forms every time hydrocarbon and sulfates combine. Plus sulfur obviously results from volcanic activity, and it’s likely the Moon was volcanic when it first formed. And sulfur is also produced through nuclear fusion – i.e., the Sun.

So what can we do with this knowledge?

Having a more complete chemical composition of the lunar south pole area means future travelers to — and possible inhabitants of — the region can also plan for what else they don’t need to bring from Earth. In particular, some scientists have suggested moon-dwellers could use sulfur in bits of infrastructure such as building materials, solar cells and batteries.

Hmmm…I think more studies are needed first…define “bits,” for example.
