As a proof-of-concept, the team wanted to develop this platform and use it to investigate the effects of microgravity and space radiation on yeast cells. And thus, the multidisciplinary AcubeSAT project was born.<\/p>\n\n\n\n<p>The project brought together ambitious students and researchers with backgrounds in STEM and biological sciences. However, the group didn\u2019t have a dedicated space department within their university where they could be guided by experts and be able to run their experiments. That\u2019s why the team participated in a European Space Agency (ESA) program to receive aid in the Aerospace domain. SpaceDot was chosen over lots of other European university teams that wanted to realize a space mission to be part of the third generation of the ESA Education Office program \u2013 \u201cFly Your Satellite 3!\u201d.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"acubesat-nanosatellite-where-space-meets-biology\"><strong>Acubesat Nanosatellite: Where Space Meets Biology<\/strong><\/h2>\n\n\n\n<p>George Pliakis, Project Leader at SpaceDot, explained that SpaceDot had the idea of creating a biological experiment in a nanosatellite after realising that less than 10 out of 2,500 spacecrafts sent into space were destined to study a system of biological nature, mainly because of the challenge it represents.<\/p>\n\n\n\n<p>The nanosatellite has an in-house built, pressurised vessel containing a microscopic Lab-On-a-Chip. This rectangular-shaped block has a lot of intricate and interconnected channels that precisely control the delivery of the liquid at a micro scale. The chip included 100 small rooms hosting yeast cells with a similar DNA structure to human cells.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2026\/01\/3D-design-of-the-nanosatellite-with-an-integrated-laboratory.webp\" alt=\"3D design of the nanosatellite with an integrated laboratory\" class=\"wp-image-19792\"\/><figcaption class=\"wp-element-caption\">3D design of the nanosatellite with an integrated laboratory<\/figcaption><\/figure>\n\n\n\n<p>Angelos Mavropulos, the coordinator of the satellite\u2019s structural subsystem, explains that the experiment relies on the microfluidic chip \u2013 a device used in studies in which the channels forming the chip are connected together to allow fluids to pass through.<\/p>\n\n\n\n<p>The microfluidic chip will allow the team to examine the effects of radiation and microgravity conditions in low Earth orbit on the cells. Each cell contains one specific protein whose production level and evolution will be observed. In the meantime, the cells will be illuminated by a ring-shaped LED PCB shedding blue light. The higher the production level of the protein, the more fluorescent the cells will be in response to the light.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2026\/01\/Closeup-of-the-microfluid-chip-\u24b8-SpaceDot.webp\" alt=\"Closeup of the microfluid chip \u24b8 SpaceDot\" class=\"wp-image-19804\"\/><figcaption class=\"wp-element-caption\">Closeup of the microfluid chip \u24b8 SpaceDot<\/figcaption><\/figure>\n\n\n\n<p>\u201cThe whole thing is actually pretty simple,\u201d states Mavropulos. \u201cWe added a high-performance camera that takes pictures of these cells. It allows us to see how much the cells fluoresce and to draw conclusions after a couple of months,\u201d he adds. The same experiment is actually being run on Earth, with the exact same settings, to be able to compare how the cells are affected by the conditions in space. The experiment will be repeated across three distinct time points throughout the mission lifespan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"a-single-protoflight-model-intended-for-flight\"><strong>A Single Protoflight Model Intended for Flight<\/strong><\/h2>\n\n\n\n<p>\u201cIn the aerospace engineering industry, there are two main approaches. The first one involves having a qualification model and a flight model. The second one involves having a protoflight (portmanteau of \u201cprototype\u201d and \u201cflight hardware\u201d), which is a single model for both qualification and flight,\u201d describes Mavropulos. SpaceDot decided to go for the second approach, as it is a more cost-effective and time-efficient option.<\/p>\n\n\n\n<p>Failure to launch the satellite on their first attempt could have a disastrous effect on the project. However, fully aware of the risks involved, the SpaceDot team manufactured a carbon copy of the satellite that will fly in orbit. The engineering team thoroughly analysed every project detail, from the mechanical parts to the microfluidic chips and the communication system. Afterwards, they started sourcing the different parts and experimenting with environmental conditions.&nbsp;<\/p>\n\n\n\n<p>The most recent test was conducted in late December 2022 in Belgium and&nbsp;<a href=\"https:\/\/www.esa.int\/Education\/CubeSats_-_Fly_Your_Satellite\/Lights_out_and_away_we_go_first_environmental_test_at_the_CSF_for_team_SpaceDot\" target=\"_blank\" rel=\"noreferrer noopener\">was a huge success<\/a>. This gave them more valuable proof that the AcubeSAT nanosatellite will be able to fly into space.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2026\/01\/Some-of-the-SpaceDot-team-members-in-Belgium-to-test-the-antenna-deployment-module.webp\" alt=\"Some of the SpaceDot team members in Belgium to test the antenna deployment module\" class=\"wp-image-19816\"\/><figcaption class=\"wp-element-caption\">Some of the SpaceDot team members in Belgium to test the antenna deployment module<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"strict-and-traceable-working-processes\"><strong>Strict and Traceable Working Processes<\/strong><\/h2>\n\n\n\n<p>On top of the challenge of managing a remote team, SpaceDot also faced the major challenge of ensuring that all of the satellite\u2019s custom components could actually be produced and fit into the relatively small structure. That\u2019s no mean feat when the satellite has to host computer telecommunications, power supplies, the entire biological lab and structural elements for maintaining the architecture.<\/p>\n\n\n\n<p>\u201cIn the aerospace industry, you need to follow the processes that are already in place and make sure whatever we do is repeatable and traceable,\u201d adds Eleftheria Chatziargyriou, the project\u2019s \u200b\u200bcommunications subsystem engineer. \u201cThis was another big challenge for the AcubeSAT project.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rapidly-sourcing-highquality-parts-with-xometry\"><strong>Rapidly Sourcing High-quality Parts With Xometry<\/strong><\/h2>\n\n\n\n<p>To ensure full compliance with the part requirements \u2013 tight tolerances, suitable materials for the aerospace industry and parts that must be assembled precisely \u2013 SpaceDot had to call upon the right providers. And Xometry was one of them.<\/p>\n\n\n\n<p>While local manufacturers didn\u2019t want to take on small projects, the team managed to get all the required components using Xometry\u2019s manufacturing services. \u201cXometry is one of the best places to source your parts in aerospace engineering,\u201d states Mavropulos.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2026\/01\/Aluminium-CNC-machined-frame-of-the-antenna-produced-by-Xometry.webp\" alt=\"Aluminium CNC machined frame of the antenna produced by Xometry\" class=\"wp-image-19852\"\/><figcaption class=\"wp-element-caption\">Aluminium CNC machined frame of the antenna produced by Xometry<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2026\/01\/PEEK-CNC-machined-features-attached-to-the-antenna-manufactured-by-Xometry.webp\" alt=\"PEEK CNC machined features attached to the antenna manufactured by Xometry\" class=\"wp-image-19876\"\/><figcaption class=\"wp-element-caption\">PEEK CNC machined features attached to the antenna manufactured by Xometry<\/figcaption><\/figure>\n\n\n\n<p>Xometry\u2019s ability to source aluminium 6082 and PEEK parts used in the antenna deployment module of the satellite was a major attraction for the team. SpaceDot was very satisfied with the metal and plastic components they received. \u201cOur particular mechanism has lots of screws and each of them has to be in the exact right place. If we misaligned one, we would have a problem with the whole assembly line. But everything went smoothly during the test campaign,\u201d&nbsp; says Mavropulos.<\/p>\n\n\n\n<p>Xometry\u2019s Instant Quoting Engine\u2122 was extremely helpful for the team during the design process. All they had to do was upload their 3D designs and technical drawings to the online platform. The AI-based algorithms let them get a quick cost estimate, apply some last-minute changes to the design and update the quote in just a few clicks. \u201cThe Xometry team was very quick to respond and helped us check our design,\u201d adds Mavropulos.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/xometry.eu\/wp-content\/uploads\/2026\/01\/Assembling-the-different-antenna-parts-.webp\" alt=\"Assembling the different antenna parts\u00a0\" class=\"wp-image-19900\"\/><figcaption class=\"wp-element-caption\">Assembling the different antenna parts&nbsp;<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"satellite-launch-planned-for-2024\"><strong>Satellite Launch Planned for 2024<\/strong><\/h2>\n\n\n\n<p>The next big milestone of the AcubeSAT project will be the satellite\u2019s launch in 2024. The whole mission is estimated to last for about a year and a half. This is the time required to collect enough information with the microfluidic chip and the images the team will capture&nbsp; during the experiment.&nbsp;<\/p>\n\n\n\n<p>In the coming months, the SpaceDot team will start to assemble the nanosatellite and go through another round of tests before the big launch.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"about-spacedot\"><strong>About SpaceDot<\/strong><\/h3>\n\n\n\n<p>AcubeSAT is a multidisciplinary project by SpaceDot, a team led by ambitious students and researchers primarily from the Aristotle University of Thessaloniki.
