Following its targeted reentry on 31 August, Samba (Cluster II FM-7), the third of ESA's four Cluster satellites, was successfully observed by the ROSIE airborne mission 2026. The ROSIE reentry observation team acquired the image with a Nikon Z8 camera operated by University of Stuttgart (HEFDiG).
Samba reentered Earth’s atmosphere at 21:39:38 UTC / 23:39:38 CEST as the third of the four Cluster satellites. Samba had been specially lined up for a targeted reentry safely over the South Pacific Ocean, with the precision so high that a plane could fly out from Tonga and successfully record its demise for reentry science.
Following the first Cluster plane campaign observing Salsa’s reentry in 2024, there were lessons learned that helped improve the data collection this time around. The ROSIE team managed to get over 50 seconds of footage with this camera, one of several so-called tracking cameras. Also, instead of just observing a few of the brightest fragments, this time dozens of fragments can clearly be seen streaking across the sky.
The tracking camera was used to confirm that Samba was exactly where it was supposed to be. It shows the surroundings, providing context such as the state of fragmentation and relative positioning of the fragments. Tracking camera images are complemented by other instruments that look for the presence of specific materials in the same field of view.
This then helps scientists identify which part of the spacecraft they are looking on their quest to understand how satellites demise exactly.

![Fluid Science Laboratory (FSL): SMD PASTA experiment
This timelapse was published by ESA astronaut Sophie Adenot on her social media with the following caption:
[🇫🇷 version FR 👇] Another experiment, and another timelapse! This time, I’m working with the Fluid Science Laboratory (FSL), one of the science facilities inside ESA’s Columbus module.
The experiment is called PASTA-3 and investigates the formation and evolution of emulsions over time when there is no gravity to interfere. Emulsions are mixtures of two or more liquids that do not usually mix, such as oil and water.
During this session, I installed 3 experiment containers 🧪 with new samples inside the FSL. Each PASTA sample has a different concentration of surfactant (an agent that helps liquids mix) and Xanthan Gum in addition to a water and oil mixture.
This experiment helps scientists better understand and model the fundamental physics of emulsions. That knowledge has numerous applications on Earth, including:
improving food quality and shelf life (milk 🥛, dough, mayonnaise, candy…),
enhancing the stability and effectiveness of medicines (including vaccines 💉) and cosmetics,
optimising processes in industrial and advanced manufacturing sectors (oil 🛢️, chemicals …).
PASTA-3 is one of the 36 European experiments I get to work on during my mission! Go science!
(PASTA is short for PArticle STAbilised emulsions experiment.)
Nouvelle expérience, et nouveau timelapse ! Cette fois-ci, cela se passe dans le Fluid Science Laboratory (FSL), l’une des installations scientifiques situées à l’intérieur du module Columbus de l’ESA.
L’expérience s’appelle PASTA 3 : elle étudie la formation et l’évolution des émulsions au fil du temps en l’absence de gravité. Une émulsion, c’est un mélange de deux ou plusieurs liquides qui ne se mélangent pas facilement, comme l’huile et l’eau.
Lors de cette session, j’ai installé trois lots de nouveaux échantillons 🧪 dans le FSL. Chaque échantillon PASTA présente une concentration différente de tensioactif (un agent qui aide les liquides à se mélanger) et de gomme xanthane, en plus d’un mélange d’eau et d’huile.
Cette expérience aide les scientifiques à mieux comprendre et modéliser la physique fondamentale des émulsions avec à la clé de nombreuses applications sur Terre, comme par exemple:
l’amélioration de la qualité des aliments et de leur durée de conservation (lait 🥛, pâte, mayonnaise, confiseries…),
le renforcement de la stabilité et de l’efficacité des médicaments (y compris les vaccins 💉) et des cosmétiques,
l’optimisation des procédés industriels et de fabrication avancée (pétrole 🛢️, chimie…).
PASTA 3 est l’une des 36 expériences européennes sur lesquelles j’ai la chance de travailler durant ma mission ! Vive la science !
(PASTA est l’abréviation de PArticle STAbilised emulsions experiment.)
