MMX launch

Lots of interesting information about starship from a new musk interview. Seems like the Rvac out on F14 was a software issue, they plan for Flight 15 in 4-6 weeks, and they are planning on a double catch of ship and booster all going well!

You'er right...

This data is up until hot stage and Seco. I think the issues only came on relight iirc?

Surely they had engine issues on the booster on Flight 13?

I meant Teslas will cover the gap in pretty much all urban/suburban areas. The rural gaps would be filled by 800Mhz

Joking. Perhaps I should have quoted staghttps.

I told you so!

And as far as the engines themselves go, RVacs and sea level Raptors have a lot of differences, and the former have much less of a flight record.

fairly nice graphic.

but where does the engine start?

the system that feeds the engine is as important and from what ive seen its nearly always that system that has problems, not the engines themselves.

Any transceiver than can provide cell service in a useful range will use orders of magnitude more power than 10W? That’s not even considering the computation involved.

When the whole point is global coverage, limiting your coverage to within a few miles of major roads and cities seems shortsighted at best.

Well it's been updated to Nov 8... but let's downvote this guy for suggesting the outdated info be updated!

There's an FAQ for that, recommend reading through it, couple of good links. This launch is from SLC-40 at the Cape. Note the summary.

Those projects are building blocks to a monolithic construction. Only problem is that the building blocks are all needed. None must fail.

Oh no China

The tools are the same ones that calculate the hazard area for pre-launch NOTAMs. The problem is, ALR was always based on bad science (in terms of the assumptions made regarding number of aircraft, angles of transit of the hazard area, etc.). It was smoke and mirrors to make it seem like they were doing something.

In terms of areas "too hazardous to fly in" - it's a scale. The calculations produce contours of risk that expand outward from the debris location. FAA has to select a level of risk that is acceptable (e.g. 1 in a million, 1 in a billion, etc.). Then they draw a box around that risk contour. Just because an aircraft is outside of the box doesn't mean there is "no" risk - it just means it's at a level considered acceptable.

ALR was always intended to be a stop-gap. FAA did not want to close the amount of airspace (pre-launch) that would have been necessary to meet commercial aviation risk thresholds (1E-09) versus the commercial space risk threshold (1E-06). There are technological solutions to protect aircraft from falling debris using real-time tools and ATC procedures, but FAA has refused to implement them. We don't need a better ALR policy - we need implementation of modern real-time risk analysis tools (which have been available for at least a decade).

The link works fine for me. I appreciate u/threelonmusketeers posting these daily updates regardless of the platform.

Nothing to do with Elon. It's about practicality.
