The astronauts will be the first humans to fly in the vicinity of the moon in more than 50 years. They will also be the first to launch aboard NASA’s next-generation megarocket and Orion space capsule. The crew will not land on the moon but will swing around the celestial body, testing the performance of the Orion spacecraft, before returning to Earth.
Mercury is a planet that just doesn’t make sense. It’s incredibly small yet hosts a relatively massive core. Mercury is so strange that astronomers have not been able to explain its properties with simulations of the solar system’s formation. But now, researchers have found an important clue, and Mercury’s weirdness appears to be the fault of the giant planets.
Basically, Mercury is nearly as dense as the Earth despite being less than 6% the size. This is due to the gas giants in our solar system yanking material (“planetesimals” and protoplanets) and ejecting it from the solar system, leaving Mercury with very little material left to form itself.
Interestingly, they position this advancement as progress in privacy rights; “In addition, they protect individuals’ privacy and the required equipment can be bought at a reasonable price,” they wrote.
An air taxi service set to feature at the 2025 World Exposition in Osaka was tested in Osaka Castle Park on Tuesday, in what the prefectural government says is the first time in the country one of the craft has been piloted from the cockpit.
The “taxi” they tested only fits one person. If the plan is to taxi visitors to the Expo back and forth between various artificial islands, I hope there are plans to test the actual three- to six-seaters.
And of course, there is always the “big challenges ahead are Japanese regulations and residents’ feelings” things. I wouldn’t be surprised if the first flying taxi to successfully taxi people around by air also becomes the first flying taxi to have a flying traffic accident.
(That’s what happened to Ohio City inventor James Lambert, who was testing an early gas-powered car when he hit a tree. Ireland claims to have an earlier accident, but it wasn’t a vehicle anything like a modern car.)
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…
For the program, the 9- to 12-year-old students designed an experiment in which epinephrine samples were placed into tiny cubes and sent to the edge of space via either a high-altitude balloon or a rocket. Once back on Earth, researchers from the John L. Holmes Mass Spectrometry Facility at the University of Ottawa tested the samples and found that only 87% contained pure epinephrine, while the other 13% had been “transformed into extremely poisonous benzoic acid derivatives,” according to a University of Ottawa statement(opens in new tab).
So…uh…why would an astronaut have this thing in space to begin with? NASA should know the full medical history of all its astronauts before even considering sending them into space.
The mysterious object’s lovely silver metallic hue stands out like a sore thumb in the surrounding, rust-colored landscape, a sulfate-bearing region of the Red Planet’s Mount Sharp.
“I’m less frightened by a Sydney that’s playing into my desire to cosplay a sci-fi story than a Bing that has access to reams of my personal data and is coolly trying to manipulate me on behalf of whichever advertiser has paid the parent company the most money.
“Nor is it just advertising worth worrying about. What about when these systems are deployed on behalf of the scams that have always populated the internet? How about on behalf of political campaigns? Foreign governments? “I think we wind up very fast in a world where we just don’t know what to trust anymore,” Gary Marcus, the A.I. researcher and critic, told me. “I think that’s already been a problem for society over the last, let’s say, decade. And I think it’s just going to get worse and worse.”
Until the new Soyuz pulls up, emergency plans call for Rubio to switch to a SpaceX crew capsule that’s docked at the space station. Prokopyev and Petelin remain assigned to their damaged Soyuz in the unlikely need for a fast getaway. Having one less person on board would keep the temperature down to a hopefully manageable level, Russian engineers concluded.
