NASA had 3 years to fix fuel leaks on its Artemis moon rocket. Why are they still happening? | Space

The question is a good one.  But I have a better one: why is NASA still using the same model for its development?

Yes, the partnerships with aerospace companies got us to the moon 50 years ago. And it helped spur a lot of innovation.  But the shuttle program was mostly poorly managed, with extensive costs, some issues with safety, and a lot of bureaucracy. 

It's no surprise that Artemis is being managed the same way.

Maybe they get everything together, and we get back to the moon.  But it sure feels like we're still stuck in the mindset of the 1960s.

Super Bowl halftime

there's some consternation about Bad Bunny being the Super Bowl half time entertainment. Conservatives hate him because he sometimes wears a dress (the horror!), and some of his lyrics are in Spanish (how terrible!). But most of all, they seem to think he's an immigrant, which he is not as he hails from Puerto Rico and is a US citizen by birth. 

So a conservative group is offering an "alternative halftime show" and is making quite the stink about it. Because it will be more 'Murican. 

I find this kind of amusing. At least in part because about 35 years ago, the halftimes kind of stank. I couldn't even tell you who was performing, but it was boring stuff. 

So one year, in about 1990, the troupe "in living color" headed by the wayans brothers, and featuring a young Jim Carrey, staged an alternate halftime show that was funny and edgy. Kind of the antithesis of what the conservative group has in mind for this weeks game. 

And in the earlier case, the numbers didn't lie. Enough people tuned away from the NFL offering that the NFL upgraded their offerings in the future. 

American CEO on Flight Attendants Sleeping on Airport Floors — “It Comes With the Business” After 9,000 Cancellations - View from the Wing

CEO Robert Isom had an investor call this week. He acknowledged the operational challenges the airline had been through, and went on to say that "I know throughout the rest of our system, some of our crewmembers didn't have a place to stay last night." And called it unacceptable  

But then added this when discussing stranded flight attendants - who had to sleep at airports - which caused more operational delays. 

"I also know it comes with the kind of business we run. This isn't the only storm that we've ever had. It's not going to be the last storm we've had."

Before proceeding to talk about profits, the government shut down (and its effect on profits), revenue sharing, and how his employees are in better shape than some competitors. 

This is how we are as a nation. Lack of empathy and focus on money have effects on people, and are consequential. 

We could be so much better.

50 times faster than trees: Live algae system reduces internal heat, resulting in more energy-efficient buildings. - CPG Click Oil and Gas

Researchers in Western Australia are using a live algae as a carbon capture method - with the added benefit that it can be used a building to help with keeping the building from heating up. That, in turn, reduces the need for air conditioning. 

This article goes into some detail by a Brazilian journalist, which appears to have been translated into English. 

It's readable, but I'm looking for additional stories about the subject, because I'd like to learn more.

It's a photovoltaic milestone since 1839 — Canada develops bioluminescent "living" cells that work even on cloudy days

In the advancement of solar cells, here's a novel approach that takes its cues from 19th century research. 

Essentially, scientists have created a photovoltaic that uses organic matter to increase the throughput and which can be used to collect energy even when full sun isn't available. 

It's a pretty remarkable feat that could further increase the efficiency, and availability, of solar power.

Russian Scientists Build Plasma Engine That Could Reach Mars in 30 Days, Leaving Spacex's Starship Looking Obsolete

Here's a bit of an innovation in space travel. A new type of engine that could propel us faster in the vacuum of space. 

The system, which uses electromagnetic fields to accelerate hydrogen particles, represents a departure from conventional chemical propulsion. If it performs as projected, it may significantly shift interplanetary mission planning across both civil and defense sectors.
