To do the math, an assuming constant volume, a 30C increase corresponds to around 10% increase in pressure. That’s well within the margins of the tyre even if you go to the max rated.
If you then consider deformation and most importantly leakage over several weeks, this is a non-issue.
I have been using Bookstack, I like it though it is missing a few features I would love:
You cannot really hide it. The launch has to be public to warn airplanes and ships so they can avoid the area. And once the launch is public, such a failure is quite evident to anyone who was interested in following it, so you might has well publish the news instead of trying to hide the unhidable.
I wear slippers inside mostly to protect agains cold floor, coffee tables, and most important of all, Lego bricks on the loose.
Also another reason to wear shoes inside is when you are constantly going inside and outside. Which means then your floor is dirty… which means you want to protect your feet from the dirt. That’s a vicious cycle but can be one of the reasons.
I am not familiar with what is required for hydropony, but I would guess it requires more equipment. Plus growing them on Lunar soil means eventually you get some elements from the Lunar soil itself and do not need to have full recycling otherwise, which means you don’t have to have a fully closed cycle for this.
There is still the issue of the closed cycle for air though (which is where Mars is easier than the Moon for medium term colonies).
It is on the Moon, it knows it can die due to decompression at any moment and we completely screw up it’s circadian cycle with 30+ days. Of course it will be anxious, no need to prove it.
Let’s see if it wakes up once the sun hits the solar panels. Hopefully the thermal conditions do not kill it by then.
I, too, have children at home.
He should have used a 2000 y.o. equipment. Romans knew how to defeat drones: https://en.wikipedia.org/wiki/Retiarius
It means that U.S. automakers find it cheaper to have their vehicles made in China and then import them in the U.S., rather than make them directly in the U.S. in the first place.
This means that manufacturing in China is so cheap that even with the tariffs, it is more cost effective to go there. If your goal with the tariffs is to level the game, then this should not happen (no one would relocate like that unless there is a massive gain).
This.
I don’t mind if they use the average household number in the title or header, that’s understandable. But such an article should have the actual values somewhere.
Can we? Yes. Should we do it right now? That’s debatable.
The question is how much this would cost vs getting a two weeks offline every 26 months?
These two weeks do not create any additional requirements (you already have to make sure the probes can survive for a few weeks without comms), science does not fully stops during these two weeks. And it gives an opportunity to do long duration maintenance on the ground segment.
Frankly, there is little need to spend >$100M for such relays satellites until we actually have a permanent human presence on Mars.
As heating network, they are and will be regulated like other energy suppliers: https://www.gov.uk/government/publications/energy-security-bill-factsheets/energy-security-bill-factsheet-heat-networks-regulation-and-zoning
That will be a nice explanation when they arrive in prison.
That’s interesting, it looks like I may have a bias on that due to my scientific background.
I always said salt, of sodium chloride for NaCl. Who is using sodium for table salt? The only time I heard that associated was when saying that table salt is a source of sodium, which is true.
Most likely because the news is in English. And why would Natrium be better on an international forum?
It is Sodium in most Latin languages (despite Natrium being Latin), in Hindi and in Arabic. And Chinese has a different root. Among the 10 most spoken languages (according to Wikipedia), only Russian is using Natrium.
By quantity of oil, I would think an oil spill is more damaging.
However, the damage from the sum of all oil spills pale in comparison to the damage of burned fossil fuels. But that’s because we try not to spill oil too much, that’s expensive to waste it.
To complete that good answer, satellites in GEO will experience eclipses 2x21 days per year (around March and September). The eclipse duration during these periods will vary from 0 to 70minutes and then down to 0 again, with one eclipse per day, around midnight.
So your solar plant in space will work 100% of the time 320+ days a year, and will have a small down time that can be up to an hour in the middle of the night otherwise. Not perfect but actually very manageable with a little bit of storage on the ground.
Overall, the main concern with these systems is the total cost, including launch cost. It is hard to tell if it will be competitive with solar + battery on the ground.
