Quote from: Jim on 08/28/2017 04:43 pmExpendable rocket are not obsolete.I think SpaceX has demonstrated the benefits of partially reusable rockets sufficiently, though I could see some wanting more evidence, which will be coming soon enough.
Expendable rocket are not obsolete.
At least large expendable rockets are obsolete.
At this point anyone not planning on at least partial reusability should rework their plans. And they should be careful about it, because in 5 years full reusability could be approaching where partial reusability is today.

This isn't to say that what happened in that period isn't good, but we seem to be on the verge of much more rapid and significant changes.Maybe. Or maybe we are on the verge of repeating history a bit, where great promises of massive cost reduction, through re-usability and otherwise, don't pan out.

Like Dragon 2 landing in the ocean under parachutes instead of setting down on Mars using rockets, etc..
I'm excited by all of the development currently underway. I fully expect to see some of these new efforts flying for a long time, and I appreciate the real change happening.
But I have worked in the launch business. I've seen a thing or two. I understand, I believe, what all of this work really costs.

Use multiple FH's and assemble on orbit.
Quote from: tdperk on 08/29/2017 02:23 amUse multiple FH's and assemble on orbit.You know that's impossible. Apollo-style lunar orbit rendezvous is the only way to go to the Moon and Mars Direct is the only way to go to Mars. Reusability doesn't work, look at shuttle. On-orbit assembly is slow and expensive, look at ISS./sarc

I don't see any major changes, so they must of stagnated tooYes, they all stagnated.Yep. Once a technology has 80%+ penetration, it enters the "mature" phase. From then on it's incremental evolutions, until a replacement comes along to disrupt it, then death/decline occurs.Cars hit maturity in the 60s. Air travel, in the 80s. Expendable LVs hit the mature phase in the 70s. Global launch rates have been declining ever since. That is the picture of stagnation. There have been incremental improvements, sure, but probably less than the incremental improvements in the automotive and aviation industries because with those the market has been increasing.It should be noted, that as we become a more global society, with a rapid global spread of information and capital, that disruptive innovations now occur on shorter and shorter time scales.

We don't know what kind of differences there are between the requirements. Despite the fact that it should be an identical satellite, it would not be atypical of the DoD to change the rules in between. At least the first time SpaceX had put in 2 bids, demonstrating that it is a poor assumption to think that these contracts are equivalent.Come on Ed, you know this.

SES today announced a change of launch vehicles and launch slots for its SES-12 and SES-14 satellites. Under the new agreements, SES-12 will be launched on a Falcon 9 vehicle from SpaceX in Q1 2018 while SES-14 will be launched on an Ariane 5 rocket early in Q1 2018. The swap of launches will enable SES to improve service quality and continuity for its customers.
