How many times do they intend to re-use each falcon? This was the third landing for this one they said and it made me think, is there a service life expectancy on these things.

That will take a while!!!

Another question, this starlink system doesn't have any kind of propulsion system, how will they know what will be covered? Are they expected to fan out only a certain distance and cover a specific area? Like a geo-stationary satellite

I think in the video it said that Superman was supposed to push them around. :)

Actually they have an impulse propulsion system that uses electricity and krypton gas.  Make more sense now?  Me neither, but it sounds like something that should be on a satellite/spacecraft.

Well without boring you guys with rocket/RCS/different types and ways of maneuvering spacecraft.  You also have reaction wheels, cold jet thrusters that are just glorified blow guns.  What is used on a given spacecraft comes down to how complex do you need and how long will the spacecraft be in orbit.

 In reality Starlink bird units will have a very short life by design. 

Most GEO birds that are launched have a service life of 10-13 yrs and weight 15K lbs or more and 50% of that weight is fuel which 90% of the fuel is used during the apogee burn the remaining 10% is used for station keeping. Usually an apogee motor(bi-prop) is rated for 100lbs of thrust. 

 I have worked some really cool projects over the years RAM/SCRAM capable of Mach 3-5 and all the way down to .25lb thrusters.  One of the more memorable was LEAP Low orbit Excto Astrotospheric Projectile, that was so much fun and really cutting edge technology, now I look back at that and say what a dinosaur but what we built with the tools we had is really amazing.

Phil,

I still get chills every time I watch a launch. I think it goes back to me as a kid watching the Apollo missions take off.

Very cool how they are deploying the 60 Satellites. "like a deck of cards fanning out".  So are they basically on the orbit path and then one by one will put on the brakes to settle in to their stationary position? I guess I am assuming they will all be on the same orbit but maybe they would be. More of a mesh?

Either way congrats! Love hearing the crowd cheer in the control room at each milestone during the launch. We don't get to do that where I work..  :sad:

That's 2 votes for the Prusa. Buddy in scouts has one and recommended the same. Has a small one said I can try out, he just upgraded.

Cool stuff as always Phil.

With the 50th anniversary of the Apollo last week, I was watching a lot of documentaries and man, those guys had balls to get on board one of those things with such relatively primitive technology.

I sometimes forget how much of the quest to get to the moon was a race with the Russians.

This is the future, all the current product we have is already obsolete Falcon and Dragon are ready for gate guard statu.   This engine is methane fueled and mostly 3D printed.  Ultimately this will go to Mars.  But we plan to build a planet hopper version  think carry C5 level cargo ANYWHERE in the world in 90 min.  We built this in 6 months BTW.  The real version will be LARGER and lots more power.

Parts can be 3D printed in a variety of metals now.  Basically a robotic welder that lays weld bead on top of weld bead to build a structure.  They can make a very strong structure per its weight because material only needs to be placed where it is required for strength.

So Phil what is the significance of the south Texas sites?

 Is it the location relative to the equator or some other factor that makes South Texas a viable spot for. Testing and launching?

It comes down to location on both fronts, about as far south as we can go in the continental US AND if the rocket blows or we blow it for malfunction then it rains down parts in the gulf of Mexico
