maintained throughout the design process.” It also has to meet the tough demands of the external environment. These include the rocket launch with its very intense vibrations and, of course, the conditions in orbit under vacuum and cosmic radiation.
With 8.41 MPixels and 4K resolution, the U3-38J1XLE Rev.1.1 is particularly suitable for this type of visualisation task. With the 2x2 binning feature, it is possible, if necessary, to reduce the amount of data to be transmitted by a factor of four and thus increase both the light sensitivity and the frame rate. Sony's IMX415 rolling shutter sensor delivers high-resolution data for detailed image analysis. Due to its extremely space-saving design, the IDS camera can be optimally integrated into this embedded application. The camera is controlled by a microcontroller, which processes and compresses the data while still on the satellite, after which it is to be sent to Earth. The software as well as the control algorithms are developed and tested by the students of the Swiss Academic Space Initiative themselves.
The demands on the system or the CubeSat are high: The latter must both provide the attachment points for the subsystems and components and ensure the structural stability of the satellite - from insertion into its launch vehicle to the end of its service life. All components must withstand the physical stresses generated by the launch vehicle during ascent and later the radiation and temperature fluctuations in space, while being as light as possible. The satellite prototype has already delivered first promising results.

The experiment is designed to run for three years. Based on the research results, various scenarios are conceivable. First, for example, the scientists would like to find out whether certain therapies could improve the astronauts’ well-being. But senescent cells can also be drivers of various diseases that make life difficult for people, especially in old age - such as dementia, arteriosclerosis, diabetes and arthritis. In addition, they are suspected of contributing to tumour progression. According to one study, SARS- CoV-2 may also be a trigger for senescence - a possible explanation for Long Covid's persistent symptoms.
The Swiss Artificial Gravity Experiment could provide interesting approaches for possible therapies. More and more IDS cameras are thus making a contribution to health promotion worldwide. “A field of application that is close to our hearts,” emphasises IDS founder and owner Jürgen Hartmann.
The cells emit different amounts of green light depending on the senescence rate. Cells with a higher senescence rate emit more fluorescent proteins and are therefore brighter.
