SpaceX does it again!!! + Rolling out Starlink

[mako88sb]

Here's a quote and image from FB SpaceX group user Ross Sackett;

"I used a trick we sometimes use to fix the position of a star in an astrophoto(graphy.) While the fireball is burned into the image making it hard to locate the center, the lens flares (probably diffraction spikes) are centered on the brightest part. Make of this what you will.

This centers near an S bend in a large strongback (electrical?) conduit near the level of the common bulkhead in S2. There are other connections to S2 near there.

L2 SpXers sound like they're focussing on something, but will wait for Musk to pull the trigger publicly."

I enjoy Manleys videos a great deal. He has his feet on the ground and knows his physics and what critical thinking means. A breath of fresh air in the madhouse on the internet this weekend over this incident.

I for one are going to wait for the investigations report.

That is wisdom right there.

Missed this somehow. First re-use of one of their flight-proven Falcon 9's:

A bit unrelated to the main theme but related to rocketry, here's a bit of trivia:

Here is a picture of one of the nuts that held the strap-on booster attached the core of the Shuttle launch vehiecle.

The Shuttle had big ones for sure. And to think every gram counts when calculating the launch.

I'm not sure if you're reading the description right. It says it's one of the frangible nuts for a hold-down bolt. Not for how the booster was attached to the rest of the launch system.

Could quite possibly be my bad for reading wrong a post where the image was linked up.

When my father retired from NASA, some of the folks he worked with at KSC gave him a plaque with half of one of those nuts mounted on it. It's quite impressive to hold even half of one.

Elon Musk's presentation for his plans to colonize Mars. I was skeptical that landing the Falcon 9's first stage booster back on Earth would be doable, especially on a barge so was very impressed when SpaceX pulled it off enough times to show it can be done. However, I must admit to finding a whole lot of what I saw in his presentation to be more of a sales pitch that needs so much to happen on a scale never seen before that I guess I'm skeptical again. For one thing, having 42 engines in the booster stage has me thinking about how well the Russian N1 worked out and it only had 30 engines in the first stage. There are many other issues but that one point really stands out for me. How many of those 42 engines are going to be mission ready for the next launch after having the fuel module loaded? Anyway, here's the video:



It will be interesting to see how the next few years go and hopefully, my skepticism is doused again.

^ Thank you for the link.

As I thought there was absolutely no conspiracy over this explosion it had a natural causes due to some technical failure and temperature.
