With just over a minute to go before liftoff, a California aerospace startup opted to stand down from launching the world’s first 3D-printed rocket on its inaugural test flight.
At least unlike the spectacular self-destruction of JAXA’s H3 this past Tuesday (Monday, Japan time), the team testing the California rocket wisely decided that it’s not a bright idea to stick a billion dollar satellite on an untested rocket. Repeatedly.
I’m beginning to feel that using 3D printed parts may not be the way to go with rocket engines…
At liftoff time, smoke was seen rising from the bottom of the rocket, indicating the ignition of the main engine. However, the rocket did not rise from the launchpad.
Also, see this one (pay wall, Washington Post) about NASA and DARPA working on one to reach Mars much faster to reduce astronauts’ exposure to radiation.
I still think “durp” every time I see that acronym 😝
Not too terribly helpful if you can’t read Japanese, but you can probably figure out which is water and which is “radical water.”
From 11 to 17 January, the Demonstration Business Promotion Team Osaka along with Sustainable Energy Inc. ran trials on a synthetic fuel produced from water and carbon dioxide present in the air. If successful, this could become the first carbon-based and truly carbon-neutral fuel of its kind.
So basically this company in Osaka did some water 💧 experiments with “radical water” (water whose molecules were subjected to a kind of electrolysis⚡️ to ionize them), then a “seed fuel” (a fossil fuel like kerosene) was added to create synthetic fuel ⛽️ which in turn will create more CO2 that can be used to create more synthetic fuel.
And no, I didn’t have to insert goofy 😜 icons, but I’m on the train right now 🚊 so why not. 😝
Anyway, this all just sounds too good to be true. Surely it’s prohibitively expensive 💴 to constantly electrify water to the point where its unbound electrons can be available to bind with synthetic fuel electrons. Tidal 🌊 generators, wind 💨 turbines, solar sun ☀️ panels, and thermal heat from volcanos 🌋 all seem more likely a source of electricity to power EVs. 🚗
At any rate, there’s been nothing in the news 📰 about this, so I doubt the experiments worked. Or if they did, someone has a vested interest in continuing Japan’s reliance on Middle Eastern, Indonesian, and Russian fossil fuels.
OK I arrived, so I can stop it with the icons 🛑 ✋ for now.
Concerned that the UA forces on Luna Base may use the quantum teleporter to send an unwelcome gift to the newly-declared independent United Mars Colonies, former Mars security chief Sergeant Major Hamels and former Artemis crew members Enoch Ryan and Brady Cooper attempted to disable the teleporter ahead of time.
Too late…
Cooper could sense the radioactive isotopes within the canister. The explosive materials could kill them and most of this part of the colony due to sudden decompression of the building’s atmosphere. Fine radioactive dust spread everywhere. If it reacted with the cobalt in the boxes around them, the resulting dirty bomb could poison half or most of the planet for years. Decades, even. Who knows how long it would last.
If anyone were around to care.
“Fly-boy, you sense that?”
“Yeah.”
“Let me try something.”
“You want the rifle?”
“The energy discharge will just set it off. That’s probably what they were counting on. Or hoping we’d try to disable it.”
“Or send it back,” Hamels said. “No doubt their end has a rigged signal to reject contact, which also would set the thing off.”
“Then there’s only one option.”
With a sigh, Enoch set the rifle down next to the console. “Coop, something tells me you need me to help.”
“You read my mind.”
“Not yet.”
Now it was Hamels’ turn to back away. “What are you both doing?”
“Sergeant Major, we need you to focus on maintaining the force shield.”
The geist sat down crosslegged on one side of the platform. Enoch sat down likewise across from him on the opposite site. They stared into the force shield, concentrating on the cylindrical container.
Since the Hayabusa2 returned with the sample from the Ryugu asteroid in December 2020, several important discoveries have been made – most notably analyzes confirming the presence of substances thought to be the building blocks of life on the asteroid, such as liquid water and organics fabrics.
Hayabusa-2 took several years to land on Ryugu (literally “Dragon Palace”), pound out just over 5 grams of asteroid material, and bring it back to Earth (landing in Australia in late 2020).
NASA scientists have confirmed not just frozen water but liquid — inside crystals called pyrrhotites. JAXA scientists (pictured above with Prof Tsuchiyama of Ritsumeikan University, my main employer!) continue to check the density of the samples.
The water is similar to the carbon dioxide-laden water of hot springs. The research teams have already discovered over 20 amino acids, the basic protein building blocks of carbon-based life.
Another theory called “panspermia” proposes that a key mineral (boron) missing on early Earth came in an asteroid from Mars. ☄️ Hmm. Did Mars produce asteroids? Or more like asteroids hit Mars and broke off lots of tiny fragments? That somehow survived the journey to Earth?
Seems a little unlikely. But there is now evidence that at least some proteins came from space rocks.
So, sorry, Ridley. This isn’t how it happened. Cool movie, though.
A new study that analyzes data from more than 50,000 amateur stargazers finds that artificial lighting is making the night sky about 10% brighter each year.
Each spring in my Current Events and Global Issues class, I have students read about environmental issues.
Pollution is obviously related. But they almost never guess the “seven types of pollution” (yes, I know some people country eight, or ten, or even twelve…it all depends on how you categorize them).
Maybe it’s because most of my students (to the order of 90%) come from medium and large cities. To me, having grown up in a mostly rural area (in elementary school, my town had about 400 residents and in junior and senior high I lived in a “queen village” that had — gasp — an incredible 4,000 residents) — well, being surrounded by darkness was no big deal.
We could see stars from our backyard. Lots of stars. We learned all the major constellations (of the Northern Hemisphere, anyway, since that’s what we could see).
And more importantly we could see lightning bugs (or “fireflies” or “glowworms” or “candle bugs” etc). Decreasing water quality is thought to contribute to their declining numbers, but it’s far more likely that our insistence on lighting up the skies all the time are preventing them from finding a mate (hence the reason they “flicker” at night).
The feat, which involved firing powerful laser pulses at thunderclouds over several months last year, paves the way for laser-based lightning protection systems at airports, launchpads and tall buildings.
A Japanese start-up (I.e., a small private company)…
using a SpaceX rocket (I.e., a private company owned by the world’s wealthiest pri…er, person)…
sends up a small craft made in Germany… 🇩🇪
along with the Rashid rover (made by the UAE)…
and “a two-wheeled, baseball-sized device from Japan’s JAXA space agency”…
and somehow this is cooperation between the US and Japan versus China and Russia?
I’m not seeing it. The project may have used a NASA launchpad, but the people are charge (and the ones paying for it) are not part of any national government.
And I have a feeling this is the wave of the future. More and more private companies will get involved in space projects as they realize that they can thus ignore politics and aim at profits.
I, for one, welcome our future corporate overlords…
