The Esrange Space Centre, which was the venue for this week, is located far north of the Arctic Circle. The local conditions were accordingly. At temperatures as low as -28 \u00b0C, the teams were able to gain an impression of the conditions their experiment will have to withstand later on.<\/p>\n\n\n\n<p>During the week, events were held every day on the topics of mechanics, electronics, software development\/programming, risk management and other project focal points. The aim was to optimally prepare the teams for the successful realisation of their experiments. A meeting was also held to discuss the design to date, including all technical solutions. Such a meeting is known as a Preliminary Design Review (PDR). Helpful hints and suggestions for changes were given in order to avoid potential problems and risks for all projects.<\/p>\n\n\n\n<div class=\"wp-block-group\" style=\"padding-top:0;padding-bottom:var(--wp--preset--spacing--50)\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\" id=\"h-critical-design-review-cdr\">Critical Design Review (CDR)<\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"250\" height=\"187\" src=\"https:\/\/wpadmin.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Personen_Bild4_web_bfd82a7251.jpg\" alt=\"\" class=\"wp-image-22385\" title=\"Work in the LEDS university laboratory\" srcset=\"https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Personen_Bild4_web_bfd82a7251.jpg 250w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Personen_Bild4_web_bfd82a7251-150x112.jpg 150w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Personen_Bild4_web_bfd82a7251-16x12.jpg 16w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Personen_Bild4_web_bfd82a7251-24x18.jpg 24w\" sizes=\"(max-width: 250px) 100vw, 250px\" \/><figcaption class=\"wp-element-caption\">Work in the LEDS university laboratory<\/figcaption><\/figure>\n\n\n\n<p>The Critical Design Review (CDR) was scheduled for mid-May 2020. This involved checking whether the problems and risks identified in the PDR in February had been eliminated and possible improvements implemented. It was also checked whether the intended final design of the experiment met the requirements and had no further errors or problems. Any need for improvement had to be eliminated quickly.<\/p>\n\n\n\n<p>Due to the coronavirus pandemic, it was unfortunately not possible to hold the CDR at the ESTEC (European Space Research and Technology Centre) near Amsterdam. Online video conferences took centre stage. Ultimately, the pandemic caused the launch to be postponed to 2021 and the launch team was expanded.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\" id=\"h-thermal-vacuum-week-tv\">Thermal Vacuum Week (TV)<\/h3>\n\n\n\n<p>The Thermal Vacuum Week took place at ZARM in Bremen from 15\/08\/2021 to 20\/08\/2021. Two important tests were carried out: the thermal vacuum test and a mechanical load test. In the TV test, the electronics were tested up to a minimum temperature of -60 \u00b0C and a minimum pressure of 10 mbar. Under these extreme conditions, the electronics functioned as desired and measured values were recorded, saved and sent correctly. The mechanical load test of the device responsible for lowering the measuring coil on the scissor arm at an altitude of several metres revealed a need for optimisation. The original solution with the release of the scissor arm and its braking by a gas pressure damper was replaced by a geared motor with a cable winch.&nbsp;<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group\" style=\"padding-top:0;padding-bottom:var(--wp--preset--spacing--50)\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\" id=\"h-campaign-week-esrange\">Campaign-Week Esrange<\/h3>\n\n\n\n<p>As part of Campaign Week from 24 September 2021 to 4 October 2021, the flights of the stratospheric balloons BEXUS 30 (with ELFI) and BEXUS 31 took place at the Esrange Space Center of the Swedish Space Corporation (SSC) in northern Sweden near Kiruna. After a short briefing and safety instruction by SSC staff, preparations for the launch could begin. Several system tests and flight capability analyses had to be carried out. The first test was the deployment test, in which the experiment, including the braincase, prime and antenna, was attached to the nacelle and the final test of the deployment mechanism for the antenna was carried out there. The extensive modification of the mechanics, which became necessary due to the tests during TV Week, could thus be tested in the final version in Esrange.<\/p>\n\n\n<figure style=\"\" class=\"wp-block-image greyd-image\"><img decoding=\"async\" width=\"640\" height=\"480\" src=\"https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Teamvertreter_vor_Ort_c9fd5e6bc2.jpg\" class=\"wp-image-22388\" alt=\"csm_team_representative_on_site_c9fd5e6bc2\" srcset=\"https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Teamvertreter_vor_Ort_c9fd5e6bc2.jpg 640w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Teamvertreter_vor_Ort_c9fd5e6bc2-300x225.jpg 300w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Teamvertreter_vor_Ort_c9fd5e6bc2-150x113.jpg 150w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Teamvertreter_vor_Ort_c9fd5e6bc2-16x12.jpg 16w, https:\/\/www.hs-nordhausen.de\/wp-content\/uploads\/sites\/8\/2024\/05\/csm_Teamvertreter_vor_Ort_c9fd5e6bc2-24x18.jpg 24w\" sizes=\"(max-width: 640px) 100vw, 640px\" title=\"\"><\/figure><\/div><\/div>\n\n\n\n<p>The next test that the team and the experiment had to complete was the communication test, in which the connection between the Braincase and the ground station was configured and tested accordingly via E-Link, which is provided by the SSC. An interference test was also carried out to check whether the various experiments in the BEXUS 30 balloon's nacelle can work in parallel without problems or whether several experiments influence each other.<\/p>\n\n\n\n<p>The final step before the launch was the Flight Compatibility Test (FCT). Here, the experiments were to work under flight conditions. For this purpose, all experiments were mounted on\/in the gondola and the connection between the experiments and the ground stations was established. The nacelle was then picked up by the \"Hercules\" (launch vehicle) and transported to the launch pad, where the final check of the functions of all experiments was carried out.<\/p>\n\n\n\n<p>After successfully passing all the tests, the BEXUS 30 balloon took off at 06:54 on 30 September 2021. The launch preparation and ascent can be seen under the following link.
