Hate when my Nasic and past performance are left unpaired

The weapon you linked to is an anti ballistic missile. The difficulty is not purely in how fast the target is going, but how much it maneuvers, the duration at which it can sustain those speeds, and the altitudes at which it operates. The article addresses this early on.

Suggest changing the title to include both parts, if they fit: "Tim Cook to become Apple Executive Chairman, John Ternus to become Apple CEO"

Totally agree. Cool little project, but I cannot think of one use case where this is needed.

> But "fine" starts to feel slow when you need dense time resolution. Generating a month of ephemeris data at one-second intervals is 2.6 million propagations per satellite.

Ok, except SGP4 loses its accuracy over WAY shorter time frames than a month (think hours/days)

> Pass prediction over a ground station network might need sub-second precision across weeks.

a) sub-second ephemeris for antenna pointing is crazy overkill, and b) same comment about accuracy as above.

Impossible claim with no evidence offered - curious why this is on the front page.

It will require a number of innovations just to solve the formation flying aspect of the system, not to mention the other challenges (listed and not)... good luck with that.

That's fascinating (and almost unbelievable) to me. Are you aware of any other books/articles/blog posts about this aspect of SV? I'm interested to learn more.

> Only one of the ones I know well involved a person actually dying, but quite a few where people were "roughed up" and are now disabled.

Pardon my language, but what the fuck? You honestly have "quite a few" stories about people being physically assaulted because they were bad references?
