It is very important to ask three questions:

1.) How do spaceship and satellite launches impact our environment, in particular the #thermosphere?

https://mastodon.social/@HistoPol/113295593037140652

2.) Who is the main culprit of this unsustainable development in orbit? (see below)

https://mastodon.social/@HistoPol/111141586398331386

(Translation: see #AltText)

3.) How do we combat it?

Translation of linked screenshot from German:

"In global communications, #ElonMusk has probably already become the most powerful man of all time via #X and Starlink in conjunction with #SpaceX

Via #NewYorkTimes

"Elon Musk's unrivaled power in the stars - with Starlink, Elon Musk's satellite dominance sounds global alarm"

So far, #Musk has launched "only" 4,500 of his #Starlink satellites since 2019.
He already has over 50% market share (global dominance).
The target is 41,000...

Aurora and the collective motion of plasma in the thermosphere

Today, we're diving into a fascinating blend of atmospheric mysteries, the origins of life, and surprisingly, the physics of sheep herding.

graphic - The pathways of the main sources of plasma to the plasma sheet during southward IMF are illustrated in a schematic of Earth’s magnetosphere (based on Fig. 1 of ref. 1). The arrows represent the approximate paths of the different sources. Orange indicates the solar wind, coming in through the dayside magnetopause due to reconnection, and flowing along lobe field lines that convect to the plasma sheet. Green represents the hot outflow from the dayside (cusp) and nightside auroral regions. Blue represents the polar wind, outflowing from the polar cap. These sources mix in the plasma sheet with the contribution of the different sources changing with time.

image - Invisible 'swirly patterns' were detected in the thermosphere for the first time ever

graphics / global maps - GOLD Level 2 data showing temporal and spatial evolution of the thermosphere during the storm on May 11. The first and second rows are the 1356 Å and LBH absolute radiances used as input to the ΣO/N2 algorithm, while the last two rows show GOLD ΣO/N2 and TDISK values. Full disk images shown are combined individual north and south hemisphere scans. Times listed at the top of each row are the time the north hemisphere scan started. A scan beginning at 08:10 UT with minimal dayside data is not shown. The black line indicates the geomagnetic equator.

global map - mean total electron content (TEC; in log base 10 scale TECu) from 15:25–15:50 UT (25-min average) projected onto the geographic map. Notice the spatial morphology over South America that is also seen in ΣO/N2 and TDISK (see Figures 2 and 3). The structure is seen forming around 11:00 UT and is visible until about 18:00 UT... The magnetic equator (and ±15° magnetic latitudes) are shown in magenta for reference.

graphic / schematic - how space weather affects navigation

world maps - Changes in the Earth's global magnetic field over six months in 2014 as measured by the European Space Agency's three-satellite Swarm constellation. The left map shows the average magnetic field and the right shows changes in magnetic field strength during that period.

charts / maps - Geomagnetic latitude versus geographic latitude for large residuals within the 80° MLON (a) around the geographic pole and (b) opposite to the geographic pole for northern and southern hemisphere.

chart / map - Example of single satellite track of horizontal residual vectors between Swarm measurement IGRF model estimation with comparison to Swarm FAC product. The blue (Swarm Observation) and red arrows (residual) show direction with the length proportional to magnitude of the magnetic fields. The inset is the amplitude of the calculated FAC for this orbit.
