Grub boot menu
By default Debian using the Grub bootloader, if you want to change a few settings you can either edit the configuration files manually
There is a section in the Debian Administrators Handbook which covers Grub, and also the LILO boot loader(s).
If you are not comfortable with this then you can use a program such as grub-customizer.
apt install grub-customizer
So the first screen you see is a list of installed operating systems.
So you can fine tune which kernel or add extra parameters.
The next tab
Allows you to customize how Grub works, you can change how long the Grub menu appears for, or hide it altogether.
You can also change how grub looks
Advanced tab should only be touched if you know what you are doing, here for reference anyway.
Don't forget to save your settings, however if you exit without saving then you will lose changes. This is good if you think you may have messed something up.

The Nancy Grace Roman Space Telescope review
In post on 6th October I posted a link to the October lecture [1] from the Space Telescope Science Institute (2).
Here is a short review of the lecture:-
The first part of this was an overview of who Nancy Grace Roman was, he connection to NASA and the new space telescope. One of the early pioneers,got started with NASA and had real vision on how space could be studied.
The 2nd part of the lecture covered the new telescope, features, and how it is hoped it will be used, but there is far more potential for science here, it will produce massive amounts of data to keep people busy and new models on how to handle, and process this data will need to be utilised.
Exciting times ahead, from studying stars, supernovae, galaxies, looking for exo planets, stars with exoplanets as they pass in front of other stars, looking for dark matter and energy and much more.
There is a related lecture to this, which was from the 15th October
Next lecture is November 10th – Astronify
Previous lecture (Sailing across the local universe-with-ullyses) is here
This has an excellent explanation of the electromagnetic spectrum and how absorption works.

OSIRIS-REx mission
Yesterday, there was an update to the NASA OSIRIS-REx mission to collect and return a sample of dust from an asteroid.
This post was prompted by a BBC Science news report. The NASA mission page can also be found here.
Mission should return to earth in 2023.
Hopefully the sample collection went as planned.
Update 21/10/2020
Mission on the way back, sample collections went successfully, should return largest sample from a foreign body since Apollo.
Follow @OSIRISREx for updates.
Discussion
Feel free to start a thread on Science Forums to discuss further.

National Chemistry Week 2020
18th to 24th October is National Chemistry week, so there are a few activities listed on the American Chemistry Society website out reach pages.
In recent chemistry news ScienceMagazine has an article on a Globular cluster in the Andromeda galaxy that appear to be deficient in elements heavier than Hydrogen and Helium.
This is interesting, there isn't that much information due to the need to sign in, but I would suspect the research papers may be more widely available in due course.
