Maybe space resources can help Earth survive. But, like the Polynesians who settled the Pacific, that's really not the primary reason humanity wishes to explore & settle this new ocean, the depths of space. (Quote below is from Christina Thompson's excellent book Sea People.)

"...Occasionally, there is famine or some other type of trouble, but usually it is a matter of chiefly ambition or pride." (Important. I've often been told the reason Polynesians explored & settled the Pacific is a desperate need for resources. Polynesians' own stories disagree.)

@SpaceKoala You should use the same unit as the tweet for better comparison. Tritium has 3.58*10^14 becquerels per gram.

Freaking out about these releases is kind of silly. Cosmic rays put about 4 kg of tritium into the ocean ever year. Atmospheric nuclear testing put 500 kg of tritium into the ocean, and the only radioactive Godzilla we created was in our own imaginations.
Radioactive Red@radioactivered

I went on a deep dive after seeing this comment because I decided I didn’t know that much about Chinese nuclear power plants… I had no clue there are legit Chinese nuclear power plants that release WAY higher annual amounts of tritium in their routine wastewater than Fukushima’s ALPS treated water discharge. I guess Fukushima just stands out because of the accident in 2011, but even with that data apparently China’s rapidly expanding nuclear program is still contributing more to ongoing tritium discharges into the ocean because of the routine operations from it’s dozens of plants. Also, Fukushima’s ALPS treated discharges and China’s routine releases from plants are still considered safe under IAEA guidelines though at least, but its still kinda crazy to me that Fukushima catches soooo much flak in public eye still. “Chinese nuclear power plants have been releasing into the ocean water containing tritium at levels up to 6.5 times higher than the annual amount scheduled to be released from Tokyo Electric Power Company Holdings, Inc.’s Fukushima No. 1 nuclear power plant, according to a document the Japanese government compiled for other countries ahead of TEPCO’s discharge. Chinese state media regularly condemn the planned release. Chinese Communist Party organ, People’s Daily, quoted an official saying, “Japan’s plan is not the country’s private matter, but a major issue that has an effect on the global marine environment and public health.” However, a Japanese government official said Beijing does not have agreements with neighboring countries on the release of tritium from Chinese nuclear power plants, nor has it provided any explanations about the matter.” Anyways, I just thought this information was interesting enough to share since there seems to be a double standard in the media regarding Fukushima sometimes, feels a bit undeserved, tbh. 😊 Source ☢️: japannews.yomiuri.co.jp/world/asia-pac…

@deltaIV9250 100t to a low altitude, low inclination parking orbit (with low margins), if you include deployer mass as part of payload as well. Everyone uses a reference orbit, so for v3, we should as well.

Isaiah Taylor - making nuclear reactors
There is no escaping jet fuel It is truly the pinnacle of chemistry, the best thing to come from the periodic table yet Nobody has yet faced the carbon single bond chain and won
Isaiah Taylor - making nuclear reactors@isaiah_p_taylor

@mzjacobson Unfortunately when you factor in oxygen, it ends up being ~3.5kWh/kg, so 3x worse than jet fuel Jets are already constrained on weight I think it’s far more likely that we just make jet fuel cheaper and carbon neutral by synthesizing it from air via externally cheap nuclear

In Alabama a man said "Roll Tide" to me as a greeting. Later that same day, the same man said "Roll Tide" as a goodbye. I asked a woman at the store what it means. She said, "Roll Tide." I asked what it means. She said, "It means Roll Tide, sugar." So I began collecting evidence. I kept a list. I am not embarrassed about the list. I have now heard "Roll Tide" used as: hello. Goodbye. Thank you. I am sorry. Congratulations. That is unfortunate. I agree. I disagree. And once, in a hardware store, as a complete set of instructions for installing a ceiling fan. I heard it said at a funeral. It was appropriate. It was the most appropriate thing anyone said that day. I began using it. Carefully at first, the way a man handles a borrowed sword. I said it to a cashier. She said it back. I said it to a police officer who had stopped me for a broken taillight. He looked at me for a long moment. He looked at my face. He looked at my taillight. Then he said it back, and nodded once, and did not write the ticket. I wish to be extremely clear that I am not claiming those two events are related. I am also not claiming they are unrelated. A man at a gas station heard my accent and asked where I was from. I told him Japan. He said, "Roll Tide." He meant welcome. I knew he meant welcome. There was no ambiguity at all. I have been in Alabama eleven days. I have one word. It has been enough for everything. I have started saying it in other states. It does not work in other states. I said it in a warehouse store in Oregon. One man turned around. He was from Alabama. He said it back. We did not speak after that. We did not have to. I say it anyway.

Believing that the age of human exploration is over is a skill issue. We can still: ‣ find ancient temples in the rainforest ‣ make the Salton Sea lush again ‣ re-fill the Great Salt Lake ‣ conquer the darkness ‣ map the sea floor ‣ explore the stars ‣ tame Antarctica

CELEBRATE! The Trump administration is mere months away from ABOLISHING the ALARA and Linear No-Threshold nuclear standards that have caused our country's nuclear reactors to cost SO MUCH more than they ought to. We can have a nuclear renaissance, if we want it!

America is two empires. One is a land empire that was conquered by rifle-armed settlers in the 19th century. The other is an oceanic/diplomatic empire built by the US Navy and the State Department in the 20th century. Isolationist sentiment comes from the type of people who built the former. Internationalist sentiment comes from the type of people who built the latter.

Some scary stats on China's militaro-industrail complex's capacity: - China casts more metal products than the next nine countries combined and >5× the US. - Its shipbuilding capacity is ~200× the US (a total-capacity figure, not per-ship speed). - It makes ~90% of the world's commercial drones, and controls ~80% of drone components. - Chinese civilian factories could retool within a year to produce ~1 billion weaponized drones annually using under 1% of existing assembly capacity.

THOMAS MASSIE: “It’s ironic that we control the House, Senate, Supreme Court, & the White House -- and we're yelling 'election fraud'? We won all the damn elections. What are we doing with that? We’re bankrupting the country. We’re starting new wars. We’re violating the Constitution. We’re not cracking down on the fraud. The problem is not the elections. We won the damn elections. The problem is that we’re wasting the opportunity voters gave us."

Lumping the Night Destroyer in with actual good things is crazy work. “We can still conquer the darkness. We can still reach the end of night, for all life unlucky enough to live near a solar field or rich person. We can still find new ways to disrupt the biosphere.”
