Kayser Italia
is a Small Medium Enterprise (SME), a private independent aerospace system engineering company, owned by Dr. Valfredo Zolesi’s family. It has been incorporated in 1986, and since 1995 it is 100% Italian property.





Stem Cell Differentiation (SCD) ready to start

Baikonur (Kazakhstan), 25 Mar 2015 - The Kayser Italia team at the Baikonur cosmodrome informed that everything is progressing well for the launch that will bring the "Stem Cell Differentiation" experiment (SCD) on board the International Space Station. The rocket has been successfully erected and the team is working on the preparation of the biological samples that will be loaded only few hours before the launch, actually scheduled for Mar, 28th 2015. 

Once on board, the SCD experiment will be operated by our astronaut Samantha Cristoforetti in the ISS Columbus module. The Kayser Italia experiment units will be inserted in the Kubik facility where will be kept at a constant temperature of 37°C. The facility will be powered by the Kayser Italia's Portable Power Supply (PPS), serving many European experiments on board the station since 2012. When completed the SCD experiment units will be kept at low temperature till they will return to ground with the Soyuz 41S together with Samantha Cristoforetti. The return is currently scheduled for May, 13th 2015.

The SCD experiment (The Principal Investigator is Dr. Silvia Bradamante, CNR, Milan) will investigate on the muscle-skeleton and aging problems that occur on the human body when in space. Experiment results could have important Earth implications on the study of the osteoporosis.


ISS Payload Design & Operation Safety

Livorno, Italy – Kayser Italia will host the "International Space Station Payload Design & Operation Safety" training course in Livorno (Italy), on 24-27 March 2015. The training course will be held by Tommaso Sgobba (ESA Ret. – Flight Safety Chair) and Paul Kirkpatrick (NASA – Ground Safety Chair). More information on the course can be found on our event page .







T-Cell Activation in Aging  - Second flight

Cape Canaveral, Florida – On January 10th SpaceX successfully conducted a second attempt to launch its Falcon 9 rocket, tasked with sending the CRS-5/SpX-5 Dragon spacecraft to the International Space Station. A total of 577 kilograms (1,272 lb) of scientific hardware is being carried within the Dragon capsule. Among them, the ”T-Cell Activation in Aging  - Second flight” experiment developed by Kayser Italia in the frame of an ESA-NASA cooperation. This experiment is the second flight in a two-part investigation. The first T-Cell Activation in Aging experiment flew to the International Space Station aboard SpaceX-3 on April 18, 2014. For this second experiment flight, Kayser Italia was commissioned by ESA to provide the experiment units and containers, as well as to support all ground and pre-launch/return activities. The experiment investigates the early molecular pathway involved in the human immune system depression in space, a phenomena that occur during aging but also while the astronauts are in microgravity conditions. The launch, initially planned on December, 16th , due to several technical reasons was delayed to December, 19th, then to January, 6th and finally to January, 10th. Two teams of Kayser Italia specialists supported all these pre-launch activities.
