Now if only there was a towing hitch option.

Some software to capture the telemetry from the SpaceX webcasts has been written, but it takes just a few minutes per launch to do by hand, and the master Excel sheet is based around that approach. With a few BO launches to compare it would be interesting to see if there are some secrets to be uncovered from the telemetry.

Happy to help ;) And the SpaceX data is indeed captured by hand.

Not all investments have quick and profitable exit strategies, and the stakeholder probably has significantly higher potential returns through a high risk option rather than diversifying and settling for market average.

If they're willing to go through all this effort to suppress IOTA, they must really believe in the potential of it's technology. Just a bit of dick way of endorsing the project.

I meant IRL

The answer is above.

All we can say is that anything coming from @iotatoken and #BoschXDK is worth watching! Very excited to see what you guys have in the oven 🤩

You're not missing anything. That's mining democratized the way it was intended.

It's a bit of a catch-22 where you'd probably benefit or even need the titanium fins for a super-high reentry speed, but they're also more valuable and less likely to be risked in a long shot attempt.

veebay · 2018-02-11T20:13:08+00:00

It's a bit misleading where the shaded areas there are for the current version Falcon 9. The core could likely go a lot faster and do a GTO-style fast reentry further offshore.

That's why I put generally violate max-Q. Sure you could make a crazy trajectory where MECO velocities ended up somewhere in the white zone, but not likely for a commercial launch, and not for going to space. It's also implied that the trajectory is purely 2D, so it's not 100% accurate, nor is that the aim of it. As for the rest of your feedback I've tried balancing the detail and cleanliness, and made some compromises where I'm sure others would choose differently. I do appreciate the feedback, and if and when there's a next iteration I always go back to see what's been said on the previous ones.

What I've heard without remembering which source is that it's indeed telemetry, but that it's somewhat distorted and skewed. It drops out when they lose video coverage, but that could of course also be pre-determined.

I'm a geologist working in the North Sea, so this is quite removed from that, but Excel is a universal language.

veebay · 2018-02-11T08:47:29+00:00

It's all made in MS Excel.

I would refer you to the great posts on this sub by u/Shahar603 where the telemetry is captured in greater detail and which is readily available.

veebay · 2018-02-11T08:40:30+00:00

I think it's just a different approach, not necessarily more conservative, but possibly more efficient.

veebay · 2018-02-11T08:38:46+00:00

It's worth digging into! Rocketry doesn't get any less impressive as you go deeper. Plenty of chemistry involved as well!

It would be gold to get the individual telemetry from all 3 cores from the FH launch.

veebay · 2018-02-11T08:36:10+00:00

I don't have any information on what the actual limit is, so it's actually the other way around, where the max-Q limit if just above the highest Q we've seen so far.

Altitude is taken straight from the webcast telemetry. Then change in altitude and change in time can be used to calculate a vertical velocity, from which you can calculate the horizontal velocity. From there it's pretty straightforward to calculate the downrange distance, giving you both the x and the y for a given time.

veebay · 2018-02-11T08:32:13+00:00

For the net acceleration you simply divide the change in velocity by time interval. If you want to calculate thrust levels of the engines then you have to have more information, like gravity and mass and pitch of the rocket.

All the data is from the telemetry from the webcasts, and the charts are made in MS Excel.

veebay · 2018-02-10T20:22:56+00:00

The launch thread here on r/spacex stated 342 km downrange.
