We have a serious difference of viewpoints that is probably insurmountable. The population explosion was going to doom us all and Covid was going to wipe us out. There is a major industry that profits from scare tactics. The careers in problem research for one that disappear if the problem...

I built a 620 square foot house with heavily insulated walls and roof. In my own self-interest to hold costs down. It took 3 years to get an engineer to do approved blueprints for my design and to get it through the permitting process. The county really doesn't like to permit small houses or...

I am waiting to see solutions to the actual problem instead of just doing blame. Live close to your job and ride bicycles works and I have done it, but it's not universally applicable. Go back to animal power??? Only for those that have never tried it. Cutting down on energy use is up to the...

If one could identify them correctly, there are likely plenty of Russian technicians that have the knowledge to get repairs done quickly. Not having the organizational and incentive structures in place is a massively bigger problem. Even bigger than the material logistics. I don't know...

We are not going to Mars. Some people may go to Mars. The question is who pays and who controls? If a few US government astronauts are going, and the taxpayer is footing the bill, then you question is appropriate and vital. If on the hand the people going are self funding, it becomes none of our...

And would make it easier to set up treatment for those that need it. And would defund the criminals that supply it.

I am not comfortable with renaming an international body of water by presidential fiat. The increasing trend over the last several administrations of action by Executive Order should be alarming to everyone regardless of political affiliation.

So many annoying innumerate concerns. 28,000 tons of CO2 per Falcon-9 flight has been repeatedly shown wrong. 550ish tons of total propellant of Falcon-9 and CO2 of 44 and H2O(x2) of 36 gives 55% CO2 exhaust maximum. Just over 300 tons much of which is burned in the lower atmosphere. So more...

So the article got both the quantity of Starship emissions and the ratio wrong. Not a very promising source.

A couple of questions. Does the open cycle suit use a tremendous amount of consumables compared to the normal suit? If not, is it likely that the system might be much simpler/cheaper/faster to develop operationally? My questions stem from a thought that a few liters of LOX might be able to...

Not referring to this flight or any other particular flights or participants. With several decades of mixed sex crews going to orbit for extended stays, it seems unlikely that nobody has ever done anything. Given the human obsession with the subject, and hundreds of healthy people that have...

A sad aspect of all this is that Boeing has such a current credibility issue that they were overruled. Boeing people say safe, and NASA says no. Would have gone the other way in previous decades. I'm with the people that think the Starliner will be 9?% likely to return intact. Perhaps not safe...

The Cape Verde Islands would be an interesting site to consider. First stage barge recovery off the coast of Africa and IIP of the second spread out and relatively safe.

the Mediterranean is busy, and clearing mariners out of large areas of it is harder than open ocean east of Florida and Texas. its also not at a great latitude, KSC is at 29 degress north, Valencia is at 39.
