threelonmusketeers, w Nuclear power on the moon: NASA wraps up 1st phase of ambitious reactor project

Seems better suited for !space or !NASA. Cool project though.

Tristaniopsis, w A sleuthing enthusiast says he found the US military’s X-37B spaceplane

If he’s an American or ally, why doesn’t he STFU?

vzq,

Because in a democracy we have a right to do research and publish our results.

Shittyretar_,

Despite the secrecy, it’s difficult to imagine the US military’s adversaries in China and Russia didn’t already know where the spaceplane was flying.

From the article.

OsrsNeedsF2P,

If he’s an American

Because many Americans realize their army terrorizes most of the world?

Our navy terrorizes most of the world. The US Army just figured out Class A uniforms. There is no reason why the Bundeswehr should outshine us in uniform design. It’s a tailoring gap we must overcome before we can conquer ze world. So you have nothing to worry about, except coming up with better comments.

danl,

It’s not a secret, just hard for amateurs to do. No doubt states with space monitoring equipment always knew. He just did it with a camera in his backyard and his laptop.

Also, he’s Finnish.

Amateur observations of the spaceplane indicate it is flying in a highly elliptical orbit ranging between 201 and 24,133 miles in altitude (323 and 38,838 kilometers). The orbit is inclined 59.1 degrees to the equator.

This is not far off the predictions from the hobbyist tracking community before the launch in December. At that time, enthusiasts used information about the Falcon Heavy’s launch trajectory and drop zones for the rocket’s core booster and upper stage to estimate the orbit it would reach with the X-37B spaceplane.

Tristaniopsis,

Ok fair enough.

reverendz, w How Venus Ended Up with a Mini-Moon Named Zoozve

Love this story.

littletoolshed, w How Venus Ended Up with a Mini-Moon Named Zoozve

The Radiolab episode was quite good, definitely recommend a listen

theodewere, w Saturn’s ‘Death Star’ moon has hidden ocean under its crust, say scientists
@theodewere@kbin.social avatar

Mimas’s ocean appears to be relatively young, forming in the past 25m years when powerful tidal forces exerted by Saturn deformed Mimas’s core, warming it like a massaged squash ball. The heated core then melted overlying ice, creating an ocean inside the Saturnian moon.

we think of glacier water as pure, the water on Mimas is brand new and never been touched

On Dec. 30, 2023, Juno came within about 930 miles (1,500 kilometers) of the surface of the solar system's most volcanic world. It made a second ultra-close flyby of Io just this week.

tunetardis, w For your processing pleasure: The sharpest pictures of Jupiter's volcanic moon Io in a generation

It’s impressive how much detail Juno was able to capture even on the night side. What I love about Io is how it’s instantly recognizable. Nothing even remotely resembles it in the solar system.

I’m calling dibs on Neptune as my family’s home base in the future!

I know it’s several billion years in the future, but I called it.

Ugh. Less money for important things, more money for war!

Shdwdrgn, w New research finds that young planets are flattened structures rather than spherical

Cue the flat-earthers who are going to jump on this while completely ignoring all other aspects including the gravity required to make this happen, and somehow claim this is scientific proof that they were right.

I don’t think flat earthers are getting their ideas from mainstream scientific websites.

5714, w Salads Grown in Space May Pose a Deadly Problem

It seems that space ecosystems are underdeveloped.

ClopClopMcFuckwad, w Salads Grown in Space May Pose a Deadly Problem
@ClopClopMcFuckwad@lemmy.world avatar

We know that the International Space Station (ISS) is home to a lot of aggressive bacteria and fungi

Damn, TILd

nokturne213, w Salads Grown in Space May Pose a Deadly Problem

Salad is good for you, generally speaking, so growing fresh greens in orbit seems like a winning way for space farers to stay healthy. New research suggests that as nutritious as space salad might be, it could pose something of a risk to astronauts.

The problem is growing leafy plants like lettuce and spinach in space can come with a side dish of bacteria, according to a new study from a team at the University of Delaware. In tests on plants grown in simulated microgravity, they were shown to actually be more susceptible than normal to the Salmonella enterica pathogen.

otter,

Interesting

I guess some of the plants natural defences rely on gravity, so without them they’re more susceptible (till we can breed a better variant)

They’re also way lower genetic diversity in anything you grow in space.

LanternEverywhere,

Sounds like not a big problem at all. Seems like they'll just have to use appropriate cleaning methods. Even in the worst case scenario they would probably just have to use food irradiation.

EDIT

In fact reading my own link i learned that they ALREADY irradiate food that astronauts eat
