RAMSES mission: RPS and MARIE to investigate asteroid Apophis' passage through Earth's magnetosphere The RAMSES space probe is a replica of ESA's Hera mission, with minor modifications to the spacecraft and some new instruments. Like Hera, RAMSES will also deploy two small satellites: the CubeSats 'Farinella' and 'Don Quijote'.

My colleague wrote a nice Blog about the #ESA #RAMSESmission

Interstellarer Komet 3I/ATLAS – UFO-Warnung? Erinnert Ihr Euch noch an den Kurzbesuch des neu entdeckten interstellaren Kometen 3I/ATLAS? Er war das erst das dritte interstellar Objekt, das von irdischen Teleskopen jemals beobachtet wurde. „3I“ ...

#ESA #PlanetaryDefence hat jetzt endlich den ersten eigenen UFO-Verschwörungsmythos.
Congrats!

8/10 Good news: we can actually deflect asteroids! NASA's DART mission successfully changed an asteroid's orbit by crashing into it. The European Space Agency is now sending follow-up observations. Planetary defence is becoming reality.

ESA's newest planetary defender has opened its eye to the cosmos for the first time

The Flyeye telescope’s ‘first light’ marks the beginning of a new chapter in how we scan the skies for new near-Earth asteroids and comets.

2/7 Despite the threat being downgraded, scientists seized the opportunity to study this potentially hazardous asteroid using Webb's powerful instruments, capturing it in both visible and thermal light.
#PlanetaryDefence #Astronomy

It’s a question of when, not if, Earth will be hit by a large asteroid causing catastrophic consequences. How do we keep Earth safe? #PlanetaryDefence has innovative strategies, including kinetic impactors & nuclear deflection techniques, designed to alter the trajectory of these cosmic intruders. 🧪

#AsteroidThreat

Two men stand next to a large television display showing an artist's depiction of the Hera spacecraft passing by Mars. On a table next to one of the men astride a laptop are two cute dinosaur plushies, one a dark green T-rex, and the other a light blue herbivore, maybe a brachiosaur.

My favourite thing about these asteroid missions is the low-key implication that we are bigmad that space rocks wiped out the dinosaurs, and we are avenging their extinction with missions like DART and Hera.

#asteroid #esa #planetarydefence

Ramses and the Apophis flyby will be super exciting for #PlanetSci and #PlanetaryDefence. On top of all the detailed science, the closeness should allow near real-time streaming of HD video from the surface of the #asteroid at the same time as some parts of the world can see it from the ground!

YR4 asteroid: The hits and near-misses you never hear about Since a potentially hazardous asteroid was detected in December, tens of others objects have come close to Earth.

According to new observations of ESA the ☄️ 🔭 impact probability of asteroid 2024 YR4 on December 22, 2032 has dropped from 2.8% to 0.16%.

Das brauchte ich heute morgen, um meinen Blutdruck etwas zu erhöhen.
Bin gestern mit Frauen u Männern von #ESA #PlanetaryDefence im vegetarischen Restaurant versackt u war noch etwas müde.
Ich kenne sooo tolle Frauen u Männer, die Großes leisten, da triggert mich so´n CDU-Blödsinn halt doch

Moin!

Am 07.10 soll #ESA #HERA starten - d Raumsonde soll detailliert untersuchen, wie stark d von d Abwehr verursachten Schäden auf #Dimorphos sind.
Ziel: Asteroiden, die d Erde gefährden, rechtzeitig abzulenken.
Ich bin beim Launch im #ESOC dabei!
