Laaadies and Gentlemen, aliens and alienesses!!

SQUID productions is proud (TBD :p ) to present a true action movie full of drama and comedy, the ultimate adventure and sci-fi movie ever, a war-story, thriller and documentary  it is:

First post of 2011

It has been some time since our last blog post but don’t worry, we have just been busy… My original idea for the first blog post was to write a year story for 2010. However you must forgive cause I have been lazy! So to make it up to you I’m now intending to write

1) A short year story for 2010, which will be posted as an separate blog post later on this week 😉

2) A brief summary of what has happened since we last wrote anything on the blog

3) A short list of the upcoming events for the projects

4) Some great news.

Well start of in the opposite direction hence here comes the great news, first of we today sent away the experiment to DLR in Munich in preparations for the bench test which will take place there during the upcoming week. The second good news, which I’m actually quite late with, is that our successors, the RAIN experiment, have been selected for the REXUS 11/12. Check out more about them at there blog http://rainexperiment.wordpress.com

So what highlights will happen in the project during the coming couple of months?

17-21 january – First of is the bench test which will take place in Munich during next week. The main focus of the event is to run through the mission time line including all events for all of the experiments in the same rocket.

31 january – 2 february –  Spin balance of the rocket

14-25 february – LAUNCH CAMPAIGN

So what have we been doing since you last heard from us just before christmas. Well as probably most of you also have done we have taken some time off. The team started to drop off as early as two weeks before christmas and some of us are still away on vacation. Somehow though we have managed to get the experiment ready for the bench test in fact it has been many late nights and early mornings, especially during the last week.

Arriving in Bremen

So after a very busy and chaotic night it was time to leave for Germany and DLR in Bremen. We had decided to drive here and we had to leave on saturday if we were going to make it. The plan was to finish all the packing friday night and leave early saturday morning… However, it did’t go exactly like planed on friday, as you may have read. So at 1.30am we decided I wold go home to sleep so we could have one driver who had gotten some hours of sleep. It proved to be a good decision since the others got no, or almost no sleep that night. But we managed to pack almost everything and get going after lunch on saturday.


We drove down to Helsingborg, where we spent the night at Gustav’s grand parents. They were really nice having food ready for us when we arrived. Sunday we spent in the car  driving from Sweden, through Denmark and finally arriving in Bremen, Germany. We was quite tired by that time but managed to find our hotel, members of one of the other teams (M-beam) and our contact from DLR and ESA. After a nice dinner and some beers, we are after all in Germany, we went to bed sleeping like logs.
Yesterday: Monday morning. Still the same tasks but another lab in another country. Continue the work we did not manage to get done before leaving SPP. This means fitting the batteries and mounting all the boards in the E-box. So far we have managed to fit it all almost together and breaking about five screws doing so. It feels a little bit taking three steps forwards and two back, but slowly we where getting there.
So finally, at about six, we had goth all the parts together and everything seemed to work fine. First we tried to connect directly to the eBox it self to make sure that we could communicate to it which worked fine but then when we had assembled the complete FFU and placed it on the RMU we where not able to communicate with the experiment through the umbilical. So we started to try to find the problem and we soon realized that the signal pins needs to go further in to the experiment in order to get the signals through. To solve this we re soldered the pins and then everything went fine. So after some long hours we succeeded with the communication which made it possible to proceed with the Electrical interface test which went perfect. This continued with a test together with the M-beam team, which are placed below us in the nosecone. This also went fine and we finally could round of for the day, which where about time since the clock where closing 9 pm fast.

 

We rounded of the evening together with some of the other teams and some of the ESA, DLR and SSC personnel at a restaurant in town.

A brief look into the ongoing work

After a weekend of well deserved rest this week has been crazy as always. As you all know we’re really trying our best to get things ready ahead of delivery. Therefore the blog has been a bit low prioritized but to at least give something I´ll add some pictures from the last preparations ahead of the real EAR last week.

 

Team night

Some weeks ago, at October 23:rd to be more precise. The SQUID team had another of their much beloved team nights. This time it was time for a more informal night at my (Gustav) place. So I Georg and David gathered at my place at two to start the preparations, the plan was to start of with some swedish and spanish specialties together with sparkling wine and then continue with tex-mex burgers and last finish of with  some great austrian dessert dumplings stuffed with nougat cream or apricot marmalade.  Somehow we succeeded with the intended menu and when the rest of the team arrived we where ready. I think I can speak for all of us when I say that we had a wonderful night, the food was delicious and the drinks never stopped coming 😉

You are welcome to judge by your self based on the attached pictures!

Disaster strikes…

Last night actually became a sad story. After all testing and working during last night everything turned out to a small disaster. So what happened really, well we’e not yet entirely sure but I’ll tell you what we observed. Last thing on the task list last night was to mount all hardware in their specified places. Due to that we had been using the eBox (the rectangular middle aluminum box where all the electronic boards are mounted) for some time it had not yet been modified to hold the ovenCutter. This meant that we had to move all the boards to a new eBox. Somewhere here something went wrong cause when everything had been mounted and we tested the communication with the experiment, suddenly magic white SMOKE started to rise out of the eBox. We’re not sure what had really happened but our theory is that during the mounting (which took place at midnight last night) somethng most have been short circuited. This lead to that the MOSFET which is used to switch of the batteries started to boil.

Burned MOSFET

Suddenly white smoke started to rise from the MOSFET

Due to this small disaster we where forced to postpone the EAR until friday. So please wish us better luck for that time.

Busy night before EAR

So today has been busy as always. The day started of with that I (Gustav), Jacob and Amer (from the RAIN team) visited Bergtorpskolan, just north of Stockholm. There we held two lectures which where really well visited. During the first one we had 33 pupils listening and during the second one we had as many as 47 pupils listening on how our project works. This was actually some kind of record for us, we’ve never had as many pupils listening to us during a school visit and of course we loved it! The pupils where all very quiet, seemed interested and asked plenty of question so it was a rather success.

However the main thing about this blog post is not the school visit but instead the much more worrying Experiment Acceptence Review which will be taking place here at KTH tomorrow. The whole team is really fighting to get everything to work in time, and as it looks right now most things will actually work tomorrow. Something which however seems to be a huge problem is the reliability of the SCALE. In the future we hope to be able to deal with it by using more standard parts but since some of the has yet to be delivered they have been custom made in the inhouse workshop. This has led to that the two different SCALE systems really seems to have different personalities and most of the times at least one of them have problems when being run. When it comes to the rest of the mechanical parts they however seems to be on place, and the electronics and software also seems to be in a working stage.

So to end this blog post I beg you all to wish us good luck for tomorrows challenge!
