As previously discussed, a gophermap is a text file. It does however require specific formatting.

When adding links to a document, you need to ensure the space between the label and filename is a tab and not spaces. I previously discussed HOW TO set up an editor to treat pressing tab as an actual tab character.

If things are not working properly, there are several things you can try in the first instance.

IParticle Interactions	particle_chart.jpg

• You can delete the area what is between the label Particle Interactions and filename particle_chart.jpg and reinsert a tab
• Delete everything after the label, (well use cut) then paste it back in, then insert a tab

This sometimes fixes any issues, it may seem strange in the gophermap that some tabs appear small and others appear longer (as if they are equivalent of 4 spaces) this seems normal.

If you want to make sure of what is there, you can use a hex editor to examine deeper in to a file.

What you are looking for are the following

Within ASCII :

• Tab is 09 decimal, Hex 09
• Space is 32 decimal, Hex 20 (Two Zero)

Find where tabs are inserted, and check the hex is displaying 09, It may look by the text field on the right that some characters appear as periods, this is I think due to the fact that the editor needs to have something to represent what is there. If that makes sense.

Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega-Constellations

Interesting paper that was published in Geophysical research letters looking at potential damage to the Ozone layer from Satellites re-entering the Earths atmosphere and burning up. The specific issue seems to be related to the Aluminium Oxidizing, and then this travels down to the Ozone layer and causes a chemical reaction.

Give the number of Satellites in orbit and the importance of the Already fragile Ozone layer, this is not good news.

You can read the research here

There is a Fediverse discussion here that is quite interesting, I have also started a Science Forums discussion

Update : 2/4/2025: To give an idea what is up in orbit, this graphic is an interactive representation of all the satellites that are up there.
Update June 29 – Satellite collisions cause a chain reaction

Update June 25 – Near-future rocket launches could slow ozone recovery

Update July 3rd – More re-entry stats

Update 3rd July Thousands of satellites are due to burn up in the atmosphere every year – damaging the ozone layer and changing the climate

Honda’s hopper suddenly makes the Japanese carmaker a serious player in rocketry

Posted to the Fediverse, so also sharing here as it is really cool. Honda, the car firm, is now building reusable rockets.

This was posted to the Fediverse. The original post from COSPAR, The Committee on Space Research (COSPAR): can be found here

This is an upcoming workshop looking at the environmental impact of spacecraft reentry in to the Earths Atmosphere.

This workshop will address the impact of spacecraft re-entry on the atmosphere. The aim is to bring together atmospheric chemists and physicists, material experts, the space industry, and international space research related organizations to highlight the gaps in our understanding of the modelling and how we can improve testing to obtain relevant data and suggest appropriate mitigation and regulatory measures. 

This sounds like a fascinating area of research and discussion, as any exploration of space needs to take into account any environmental impacts.

Workshop information

It will be interesting to learn about the findings and conclusions from this, as it will open up further discussion on the topic(s) raised.

More interesting findings about the early universe, I guess some of this makes sense as one of the 4 fundamental forces is Electromagnetic forces.

This research findings are detailed here. So if I understand this correctly, the early universe processes had that were had electrically charged dust particles, these produced magnetic fields as they moved around by the radiation from the 2nd generation of stars.

There is a related paper on arXiv on this research.

Temperamental stars are distorting our view of distant planets

Interesting research looking at some interesting issues faced when using transits to find planets around stars. We know the transit causes starlight to dim, from the viewpoint of the observer. However, according to this research, so does changes to the star, hot and cold regions and how this impacts star brightness could be impacting how we detect planets.

The article can be found here on Science Daily. There is an article on transits on the NASA website.

I guess it would not be Christmas without a big space event taking place. 2024 is no exception, this year is the turn of the NASA Parker solar probe attempting the closest flyby.

I was reminded about this after seeing the BBC headlines today, mission details are below.

Should be able to discuss further on Mastodon or on Science Forums.

So back to some Physics videos, what is space-time?: This video does a really nice job of explaining this in a way that is understandable, but not so simple it loses any meaning.
