Załoga ISS rozbudowuje obecny sprzęt, demonstrując tworzenie złotych nanosfer w warunkach mikrograwitacji.
Są one większe i bardziej jednorodne niż ich ziemskie odpowiedniki i znajdują zastosowanie w diagnostyce i leczeniu raka oraz w ulepszonych lekach.
Astronauci w tym celu pobierają próbki z zamrażarki MELFI i umieszczają je w przemysłowych kasetach krystalizacyjnych, a następnie są dostarczane na Ziemię w celu przeprowadzenia dalszych analiz.

M+38: One of the experiments we’re conducting on the @Space_Station is to expand on current hardware, demonstrating the creation of golden nanospheres under microgravity conditions, which are larger and more uniform than their Earth-bound versions, and have applications in cancer diagnostics and treatment and improved pharmaceuticals.

We obtain our samples from the MELFI freezer and grow them into our Industrial Crystallization Cassettes, and will package them for return on Spx-32 for additional analysis.

(ciąg dalszy): Temperatura w zamrażarce utrzymuje się na poziomie -98 °C.
Otwarcie MELFI to jak podmuch arktycznego powietrza prosto w twarz. Temperatura w zamrażarce utrzymuje się na poziomie -98 stopni Celsjusza!
Na filmie widać skrupulatne kontrole i ponowne kontrole próbek oraz procedur.

M+38 (continued): Opening up MELFI is like getting a blast of arctic air in your face. The freezer is kept to -98 deg C!

In the video you’ll see meticulous checks and rechecks of our samples and the procedures.

It seems slow, but being meticulous to conduct experiments without mistakes is crucial to ensure we are doing our best job to enable the science results that so many research teams on the ground have worked years to plan for.

It’s a huge honor for us on the ISS to conduct their experiments and we couldn’t do our jobs without amazing ground support.

Procedury załadunkowe.

M+40: So what is it like to load a space cargo vehicle? It’s not too different from what you would do to pack for a move or ship a lot of cargo. It reminds me of building pallets before deployments.   

First, we work off a synchronized checklist that our amazing @NAS inventory stowage teams develop, find the items in the @Space_Station that are called out, double check that the serial numbers and barcodes match, pack the items and if necessary cushion them with bubble wrap and foam, and load them into the cargo space vehicle.   

The cargo vehicle’s center of gravity and mass calculations for re-entry depend on everything being packed in the correct order and orientation, so attention to detail matters.   

Finally, the straps have to be tightened and finished off with half hitches.   

Some of the precious cargo returning to Earth on Spx-32 are our science experiments, where ground teams eagerly await to get the experiments to the correct labs for additional research and analysis. 

It’s a lot of work but also fun, and we have a great team on-board and on the ground.
