🛰28 April: the EU launched 2 new Galileo satellites!
Earlier this morning, the Galileo satellites were ejected from the launcher's upper stage & reached the Holding Point. They are currently managed by #EUSPA as part of the Launch & Early Orbit Phase (LEOP).
What happens now?
Over the following days, the EUSPA LEOP team will be manoeuvring the satellites from the dedicated #Galileo Control Center in Oberpfaffenhofen, Germany until they are placed into their home orbit at 23 220 km.
Today I stumbled upon the phrase "Eppur si muove" ("and yet it moves"), tenuously attributed to Galileo after being forced to recant his claims that the Earth moves around the Sun to avoid being punished by the church.
The impact and rhythm of the phrase really inspired me, so I wrote a poem about it.
#DYK that the data provided by #Copernicus and #Galileo, 2⃣of the components of the #EUSpace 🇪🇺🛰️Programme, are helping health authorities monitor parameters essential for our well-being?
This includes:
☁️Air and💧Water quality
🌞Solar radiation
and many more!
The Roman Inquisition in the 1500s was constantly complaining about its desperate lack of personnel (not enough Inquisitors, not enough censors to read books, not enough police) as it tried to keep up with the exponentially-growing flood of books enabled by the newfangled #PrintingPress. Why would such an organization waste hundreds of man-hours per copy on crossing out pages when they could have trivially burned the book and moved on?

"The Inquistions didn't set out to silence #Galileo...it could have just assassinated him....Instead, the Inquisition persecuted Galileo, in a very high-profile manner
...The point of persecuting Galileo was to convince Descartes to self-censor... [and] "thousands of other major thinkers of the time wrote differently,...because they self-censored after the Galileo trial."
#Iris2: the architecture of the #European Internet constellation soon to be revealed. The European Commission is due to receive their proposal by February 14.
IRIS2 is set to become #Europe’s third satellite component, after the #Galileo (geopositioning) and #Copernicus (Earth observation) systems. Its main mission will be to guarantee the security of government telecommunications and public services while providing global Internet coverage.
#GNSS Safety Improvements such as #Galileo's Navigation Message Authentication should be adopted faster, with GPS interference levels on the rise in Europe.
Let's get ready for Juno's highlight of the year - an extremely close flyby of Jupiter's moon Io!
The NASA Juno spacecraft will make its 57th flyby of Jupiter (Perijove 57) on Sat Dec 30 around 7:39 a.m. ET (12:39 UTC).
A few hours earlier, around 3:36 a.m. ET (08:36 UTC), it will swing by the Galilean moon Io at a distance of 1,500 km. The record will still be held by the Galileo spacecraft which came within 200 km in 2000.
Here is the iconic image of a volcano eruption on Io captured by the Galileo spacecraft on June 28, 1997 from an altitude of ~600,000 km.
The plume on the left is over a caldera named Pillan Patera. The plume was also detected by the Hubble Space Telescope.
There is another plume named Prometheus over a volcano near the center of the image.
Let's hope Juno catches a volcano in its act on Io!
Verspätung der Ariane 6: SpaceX soll Galileo-Satelliten ins All bringen
Weil sich die Ariane 6 weiter verspätet und mehrere Galileo-Satelliten auf ihren Start warten, soll SpaceX einspringen. Noch ist der Deal aber nicht final.
Well… one could argue they they didn’t need a fancy satellite to tell them this 🙃 “High-resolution images of #Australia and #Antarctica obtained as #Galileo flew overhead did not yield signs of #civilization.”
🌊 ASGARD, the game-changer in maritime security! Co-funded by #EUSPA, leveraging the #Galileo OSNMA, this technology is set to safeguard vessels from GNSS spoofing attacks. #WorldMaritimeDay#EUSpace
