ESA Cluster

Four spinning spacecraft flying high & studying solar wind interaction with Earth's magnetosphere #Rumba, #Salsa, #Samba, #Tango

@pimenteljm @diogogtome [Bruno] bem há 2 anos eram 22,5 horas, hoje, pelas minhas contas devem ser 23,14 hr, ou seja quase um dia... o erro não foi esse :)

@pimenteljm @tor31890388 [Bruno] e a outra pista que liga as duas está na imagem dos artigos de merchandise!

[Bruno] Na analogia referia-me à distancia a que o lander é separado da nave mae na chegada a Marte, o que é feito a 1 MKm de distancia - essa parte está ok - quando mudei de escala dividindo tudo por 1000, fica 1000 km que é a distancia em linha recta aproximada de Lisboa a Barcelona

We hereby declare the Cluster II Science Mission successfully concluded from the Operations team side - after 24 years, 1 month and 14 days since the achievement of its formation on the 16-08-2000. So long Cluster, forever the 4-spacecraft formation mission in the magnetosphere!

[ESA Cluster @ESA_Cluster]

Last night, at 00:00, we have switched off the payload on all the remaining spacecraft and this morning we have successfully downlinked all the remaining science data on-board.

[ESA Cluster @ESA_Cluster]

@beej69 @AschbacherJosef Those are actively controlled re-entries. By targeted we mean, we've targeted the re-entry conditions well in advance (in this case back in January)

[ESA Cluster @ESA_Cluster]

With this first-ever targeted reentry, Cluster will go down in history for a second reason – taking ESA well beyond international standards, and helping ensure the long-term sustainability of space activities.

With the reentry of its first of four satellites, it's time to bid our Cluster mission farewell. After 24 years in space, this marks the end of science observations for the prolific mission. https://t.co/Xxfzjp8tGA

With the reentry complete, we're hoping to learn more soon about the results of an airborne observation experiment. With the plane three hours from land, we wait patiently for further information.
We’ll be back tomorrow with an update. More info via our blog 👉 https://t.co/Iz4LWYRN2I
For now, thank you for following and goodnight!

Right about now, Cluster's Salsa satellite is taking the plunge into Earth's atmosphere.

Farewell, Salsa! Thank you for your service!🫡

@esaoperations It's been a blast! Thanks for everything @esaoperations.

[ESA Cluster @ESA_Cluster]

A few minutes ago, the Cluster operations team successfully listened one final time for Salsa via the Estrack ground station in Kourou.
Communication with the satellite has now reached its end.

[ESA Cluster @ESA_Cluster]

@Astro_Aure We're defining it as the moment that Salsa comes within 70 km from Earth's surface; around this point, we expect the satellite to start breaking up.

[ESA Cluster @ESA_Cluster]

🆕 Latest news on Salsa. The satellite is expected to reenter at 20:47 CEST (18:47 UTC) today, with an uncertainty of just four seconds either way.

With just one hour to go until reentry, find out what we're doing and why 👇 https://t.co/ALZziQ3HAL

[ESA Operations @esaoperations]

The exact moment on Friday when the @ESA_Cluster operations team recovered Salsa for one final orbit after its searing hot final perigee knocked the spacecraft into survival mode. That final orbit comes to an end in just ~90 minutes. 👏🥲

@transtage05 Something like this? https://t.co/Q9uxKPvuVg

🆕 Latest news on Salsa. The satellite is expected to reenter at 20:48 CEST (18:48 UTC) on 8 September 2024, with an uncertainty of two minutes either way 👇

We're getting closer and closer to waving this satellite a goodbye forever 🥹
