The table of contents feature is killer.

The AsciiDoc docs got an overhaul 2 years ago. I find them to be quite good.

What are enumerated values? Do you mean ordered lists?

5 meters. However, the "intended target" is not simply defined.

The landing ellipse for Perseverance was 7.7km by 6.6km. The goal is to land at a safe spot within the ellipse rather than land at a specific location.

The new Terrain Relative Navigation capability determines the rovers position relative to the surface during descent by comparing camera images to onboard satellite imagery. On Earth you'd use GPS. No GPS on Mars.

Once the rover knows it's position, it can now determine the safest spot to land using an onboard hazard map. The spot it chose to land at vs the spot it actually landed at was 5 meters apart.

One take on this study: https://www.youtube.com/watch?v=NyGZW8Ml9l0

A few points:

* It is a legitimate unbiased study

* Need to consider the database used. It follows people starting in the 90s. A lot has changed with respect to vegan diets since then.

* Consuming sufficient calcium shows no additional risk in fractures

* More body weight (e.g. overweight) makes bones stronger which reduces risk of fractures
