Fragmentations without collisions were the main cause of the creation of #SpaceDebris in 2024, according to #ESA. There are around 54,000 objects in Earth orbit with a diameter of more than 10 centimeters and 1.2 million between 1 and 10 centimeters, between 1 millimeter and 1 centimeter around 130 million. heise.de/en/news/ESA-report-wa

ESA report warns of space debris and overcrowded orbit.

As the number of satellites increases, so does the amount of space debris in orbit, writes the European Space Agency in its latest the Space Environment Report 2025.

It warns that some orbits are becoming cramped and calls for the removal of space debris.

ESA Report Says There's Too Much Junk in Earth Orbit (via Science alert.com)

The problem of debris in Earth orbit is getting worse.

The amount of space debris is rising quickly. We're sending satellites up at a much faster rate than they come down.

Latitude Completes Hot Fire Test of Flight-Ready Combustion Chamber - European Spaceflight

sh.itjust.works/post/35803223

sh.itjust.worksLatitude Completes Hot Fire Test of Flight-Ready Combustion Chamber - European Spaceflight - sh.itjust.works> French rocket builder Latitude has announced its successful completion of the first hot fire test of a flight-ready version of its Navier rocket engine’s combustion chamber. > > Founded in 2019, Latitude is developing a two-stage rocket called Zephyr that will initially be capable of delivering up to 100 kilograms to low Earth orbit. The company is currently targeting 2026 for the rocket’s inaugural flight. > > On 8 April, the company announced it had reached a significant milestone in the development of Zephyr with the first pressurised ignition test of the Navier engine’s combustion chamber in its flight configuration. The ten-second test was conducted at the company’s Titan testing centre in Vatry, near Reims, using its new, purpose-built test bench. According to the company, the data collected from the successful test will inform its upcoming long-duration tests. > Zephyr, which will stand 19 metres tall, will use seven Navier engines on its first stage and one vacuum-optimised Navier engine on its second.

Gestern war ich live bei Astro & Co mit einem Update zu #ESA #Euclid. Wir hatten gerade unseren ersten "Q1" Datenrelease von 63 Quadratgrad. Ich erkläre was dahinter steckt, welche Projekte schon gemacht wurde und wie man an die Daten kommt.

Astrodon - The Astro CommunityHaus der Astronomie (@hausderastronomie@astrodon.social)Am 19. März 2025 hat @ec_euclid seinen ersten großen Datensatz veröffentlicht, und darin steckt weit mehr als nur beeindruckende Aufnahmen tiefer Himmelsfelder mit insgesamt 26 Millionen Galaxien: Bei vielen sind feinste Strukturen zu sehen, außerdem wurden Form und Entfernung von über 380.000 Galaxien bestimmt. @knud@mastodon.social verrät uns morgen Abend um 19 Uhr live bei Astro & Co, was man aus diesen Daten lernen kann https://www.youtube.com/watch?v=WASIVdrYDRo #Online #Livestream
