High-tech testing in the MUSCAT workshop


We are doing some quick´n dirty electrical tests for the RMU electronics.  Works fine! Very pretty


Jump from the Stratosphere


If you haven’t already seen it, take a look at this awesome video wherein Felix Baumgartner jumps from the stratosphere, breaking three world records; the altitude record for manned balloon flights (39 km), the highest parachute jump (39 km) and the greatest free fall velocity (1342 km/h).

Just imagine, he went only to half the distance our spheres are going to go but broke three records.

Take care! 😀

Ejection Test

One of the main events for the MUSCAT team next month is the ejection test. As soon as the RMU cylinder arrives we will have an entire day (plus the weeks that are necessary to plan it) to focus on this very important moment of the mission: when the FFUs are ejected from the RMU.

Our most important objective with this test is to verify that there are no mechanical or electrical failures upon ejection, since those could put the whole mission in danger. But besides that, we also want to know if the FFUs stabilize around the vertical axis and we want to be able to compute the FFUs’ ejection velocity.

This test can actually be divided in two separate parts. In the first one the RMU will be mounted on top of a fixed table and those are the conditions with which the FFUs will be ejected. This is called the static ejection test. In the second part we want to make it more realistic. During the mission, the RMU will be spinning at 4 Hz, so we are aiming to recreate those conditions for the spinning ejection test by using a spinning table.

The whole test will be recorded by of high-speed cameras that will help us to analyze the ejection. And of course we can also use the data recorded by the internal sensors of the FFU.

The RAIN team performed some very similar tests that are recorded in the video below. Check how the spinning test can become quite dangerous!

Malardalen University Visit

Hello everyone,

Last week, me and Andreas visited my old university where I earned my bachelor degree, Mälardalen University (Mälardalens högskola) in Västerås. We held a presentation about the MUSCAT experiment and the REXUS project in general. Additionally, we provided information about the masters programme in Aerospace Engineering at KTH which they can apply to when the are done with their bachelor degree.

Below a view is seen of the MdH campus area as well as a picture from inside the lecture room where we were. The overview picture of the MdH campus was taken by me some time in July when I was in a helicopter which flew over the city.



Rocket Components – PICTURES

Finally, finally, what you’ve all been waiting for… Presenting the MUSCAT RMU, actual flight hardware:

Now, this is not the entire RMU. We’re still missing the lower cross (The module is upside-down), but you get the idea. We are currently producing component at full capacity in the KTH workshops, and all externally produced components are in production, arriving later this month.
Things are looking good for team MUSCAT, the completion of this project is so close now we can almost taste it 🙂
