But et al. is by far the most published author, so they are at least sharing in the most prestigious title.

Corn has very shallow roots and aggressively pulls nitrogen out of the soil. Prairie plants are much more diverse than just grasses and many have very deep root networks extending down 6+ ft. Corn fields are nothing like a prairie habitat.

He was planning to retire 6 months ago, but the market hasn't been doing great and his brother in law had to borrow some money to deal with gambling debts.

As the current owner of a 1930's era property with tons of glass and rubble in the ground, please don't. We have landfills so that individual properties don't get filled with trash.

I dread what would happen if steam ever starts going to the dark side.

The aluminum version would be preferred, but what you linked will do just fine. I can't find a small tin of the aluminum version on Amazon, so don't bother overspending on a large container.

If you are going up a thread size, make sure you get the appropriate drill bit. You need to drill out the hole before tapping. M5 usually calls for a 4.2mm predrill.

Imo for a single job, I'd prioritize getting some tap magic over worrying about tap quality. For aluminum, tap magic makes a big difference.

Do you have enough margin to drill it out and retap to an m5 thread?

That's $700 for a digital only edition without a disk drive or vertical stand. It's $810 to match the features of the PS5.0

The ISS has gone through multiple reboosts to gain altitude because there is a small amount of atmospheric drag in its orbit. That's not the limiting factor though.

The structure is aluminum. Aluminum accumulates fatigue damage every time it flexes. Every time the iss goes from sunlight to the earths shadow, there is significant thermal expansion/contraction. This fatigues the structure. The repeated docking maneuvers also stress the structure. Radiation and atomic oxygen also cause degredation. All those factors are relatively minor in any given year, but are always accumulating. The ISS is getting less safe and the risk of a structural failure is increasing.

On top of that all, a bunch of the systems on board were designed 30 years ago. There have been major changes in communications, power systems, etc. in the time since the modules were built. Even though new experiments are built all the time, they are still constrained by capabilities of the capsules they operate in. So there are also science advantages to moving to a newer platform.
