SpaceX Lands Stage 1 on Land!

Ashenkase says...

While the Blue Origin vertical landing is difficult and an accomplishment in its own right comparing it to Spacex is a little unbalanced:

Twice the speed, twice the height, more burns, a more complex flight path and a much larger, thinner vehicle to name a few differences.

You may want to watch this video on what Spacex has planned for the remaining stages of its stack:

To be fair that stack has the Dragon capsule on top and not a satellite delivery bus but the goal to return multi stages is part of the Spacex vision.

"If" Spacex can get the "heavy" version of their vehicle up and running with stage return they will be a force unequalled in launch across the entire industry. That is if they can turn around their stages without compromise to structural integrity.

The booster is not orbital. It's on a ballistic, suborbital flight just as for the Blue Origin booster. The second stage goes to orbit and note that they are not trying to recover that one at all, let alone land it.

In fact, the SpaceX booster does several deceleration burns in space, and so experiences less aerodynamic stress than does the Blue Origin booster, which actually flies faster, according to the article I linked above.

Let's be honest, the Senate was a bribe to get the small states to join the union. But that's the way it is.

But I'd like to think that if we had multi-stage elections, that would allow for more rational centrists. They wouldn't have to appeal to the lunatic fringe of their party to get elected, they could afford to appeal to a little from the left and a little from the right.

And yeah, the filibuster rules have got to be changed. But if we had more than two parties, would there really be a reason left to have filibusters at all? To be honest, I don't see how it's useful right now...

But on to the reform package. In my mind, the most important changes are "no more denial of coverage for pre-existing conditions", and "affordability respecting the individual's income bracket".

I see movement on the first, but not the second. Is there something in the bill that will prevent insurance companies from raising cancer patients' rates to unaffordable levels?

Top 30 Failed Technology Predictions (Science Talk Post)

rasch187 says...

5. “To place a man in a multi-stage rocket and project him into the controlling gravitational field of the moon where the passengers can make scientific observations, perhaps land alive, and then return to earth – all that constitutes a wild dream worthy of Jules Verne. I am bold enough to say that such a man-made voyage will never occur regardless of all future advances.
— Lee DeForest, American radio pioneer and inventor of the vacuum tube, in 1926

Spoken like a true visionary. This was *quality stuff.
