Heavy Element Alchemy

Interesting article from SciTechDaily about the formation of the heavy elements.

This infographic may also be of interest, it is published by c&en.

Nuclear weapons in space

Interesting article and video on what could happen if nuclear weapons were detonated in space.

Link to article and video here

What is interesting, and I did comment on this point is that if an EMP pulse takes out enemy facilities, they can also take out facilities by the country using that weapon too.

Video still makes some useful points.

Intuitive Lunar Lander

“Intuitive Machines' IM-1 mission made history on Feb. 22, with the first successful Moon landing*

This will be the first of several missions before the next Atemis mission to fly a crewed mission around the moon, before the Artemis III mission to land humans on the moon in a few years.

Exciting times ahead. You can read more about the IM-1 mission here

Stsci lectures Feb 2024 update

I have been catching up on these lectures as they are fascinating. The LISA talk was also good as it gave a lot of background information as to the science behind this. Exciting times to come, even though it may be a decade before the mission is launched in to space.

So far I have watched:-

Understanding the Atmospheric Effects of Spacecraft Re-entry

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.

Understanding the Atmospheric Effects of Spacecraft Re-entry (10-11 January 2024): Overview · Indico at ESA / ESTEC

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.

Light sails

Interstellar travel could be getting closer. This paper (or at least a link to it) was posted on to the Fediverse.

Broadband, High-Reflectivity Dielectric Mirrors at Wafer Scale: Combining Photonic Crystal and Metasurface Architectures for Advanced Light sails

Sounds promising and at present does seem smaller spacecraft can be moved in this way, but it is a start. Good possibilities for future research and use.

I will download and read this paper later.

There are 40 quintillion black holes in our Universe

This is a huge number, I think this something like 40 10^24

or 40,000,000,000,000,000,000,000,000

Which is according to Scientists is the estimate of the number of black holes in the galaxy. The article on big think is here

This is why we use SI units and express huge numbers in powers. So 10^6 is a million or 1,000,000 for example.

It also makes it easier to multiply together as

10^6 x 1000 = 10^6 x 10^3 = 10^{6+3} = 1,000,000,000 or 10^9
