SPACERACE met with president of the Czech Republic | September 2023

SPACERACE presenting ATLAS hold down and release actuators to president and business community

SPACERACE had an opportunity to be 1 of 10 companies to present their vision to Czech president Petr Pavel and representatives of South Moravian county. The meeting was charged with positive energy that will fuel us for quite some time 🚀. Mr. president seemed delighted to hear that our ATLAS hold down and release actuators can safely hold his whole limousine if needed ...until he learned we can release it in miliseconds too :-).

Prototype test campaign finished | June 2023

The test campaign of the prototypes of ATLAS hold down and release actuator and it's Initiation Control Unit (ICU) is nearly finished with more than 100 full preload releases with the same hardware! As advertised, reset of the device can be done within 30 seconds. The prototypes served as a design demonstrators that are now followed by qualification models - final products which will undergo harsh and unforgiving full qualification to be ready for the market in early 2024.

Mid Term Review successful | May 2023

SPACERACE company was selected by ESA Business Incubation Centre Czech Republic for the development of ATLAS release actuators for ground testing of space mechanisms. This achievement, among other support, secured 50 000 € for the actuator development.
Use of ATLAS will enable our customers to properly test their mechanisms both at a lower cost and at a higher rate than was possible before. The first ATLAS units will get our customers faster in second half of 2023.

Hold down and release actuator

Hold Down and Release Actuator ATLAS

Testing and qualification of space mechanisms can be slow and painful process. Especially when release actuators are involved. Some of these devices can be only fired once and then sent for refurbishment to the United States. Some can be refurbished on site in exchange for high costs and considerable time spent with resets. Some of the new generation devices are resettable, but are limited in number of releases. We have been there and we decided that we do not want to select the least evil.

So we are creating ATLAS. Early 2024 SPACERACE will bring a rapidly resettable substitution of space qualified release actuators for ground testing. Resettable under 1 minute only with supplied tooling directly on the tested article. Designed for efficiency, ergonomy and reliability. Designed to make you faster.
