Neat time lapse video of a bunch of different plants (and fungi) growing from seed to flowering/fruiting.

We planted a variety of plants, at different stages of growth. After a bit of experimentation, cosmos grow extremely well. These were cuttings we put in just a couple weeks ago, and they're already bigger than most of the other plants that have been in there for over a month.

The very young plants did not survive, but the larger ones did. If they're too small, they just get swallowed down into the cups by the bobbing of the water.

Seems like the plants need to be large enough to reach all the way to the bottom of the pots, and still stick out enough.

Going to be interesting to see what it looks like at the end of the season.

The experimental mat has been out for about a week now, but extremely high winds during a storm last night pulled up a corner of the mat spilling out the contents.

Luckily the majority of the plants were able to be saved, so we have one empty spot now.

I added some weights to the four corners to hopefully prevent this from happening again.

This is why we're experimenting! Learning what works and what doesn't with the setup.

Our retention pond in our neighborhood has a lot of algae and problematic plant growth due to the surrounding farms and lawn runoff, so we're experimenting with a floating island to pull nutrients out before they can cause problems. This will also provide some interesting flowering plants, and more fish habitats.

Will be an interesting experiment to see what survives and what does poorly.

Zinnias, sunflowers, marigolds, and a few others are in net pots, inserted into cutouts in EVA foam mats.

Really important step towards expanding our research on the moon, is creating highly detailed maps of the entire surface.

China is doing some great work on building out infrastructure and studies of the moon. They're the only country that's brought back any moon rocks in decades.

Space Race 3.0 is on, and we'll see how different approaches to the research and manned missions will move forward.

The US is currently building out an extremely upfront cost heavy project, but with a lot of long term benefits.

China is building a more straightforward moon project, but with higher ongoing costs, as much of the infrastructure is disposable (more like Apollo).

The amount of detail in these pictures is amazing. You can really see the texture in the nebula, and the features are so crisp, it kind of looks 3d.

Pretty interesting topic, would be interesting if it could be used to move satellites to a "parking orbit" once they run out of fuel. It's unclear just how much movement in an orbit that can be done, as it says it needs to be in the same energy level.

If there’s a Holy Grail on Mars, it’s probably a specific type of rock: A rock so important that it holds convincing clues to Mars’ ancient habitability.

Perseverance might have just found it.

Didn't work out at all, but wanted to share a conversion of a dobsonian telescope into a horseshoe mount that I built a while back. Was a completely failed experiment, but it was also kinda fun.

There was an issue on Reddit a while back where people would post some hateful stuff, and of course lots of people blocked them.

After a while, anti-trans, racist, and far-right-wing stuff were only seen by non-logged in users, other bigots, or new people, and they weren't getting the downvotes they deserved.

Is this going to be a problem on Lemmy too? I'm worried that if we're all blocking shitty users that we're just hiding the problem from ourselves, not fixing it.
