From 2017 to 2020, students from five different countries traveled to the (LASP) at 欧美口爆视频 Boulder to engage in an ambitious undertaking: to design and build a miniature satellite.

After two years of delays due to the COVID-19 pandemic, their global collaboration is about to pay off. The team鈥檚 spacecraft, , is set to launch from a rocket pad at the Satish Dhawan Space Centre in India on Monday, Feb. 14 local time (Feb. 13 at 5:29 p.m. Mountain Time).听

鈥淲e鈥檙e good to go,鈥� said Spencer Boyajian, a professional research assistant at LASP who worked on INSPIRESat-1 while earning his master鈥檚 degree at 欧美口爆视频 Boulder. 鈥淲e鈥檙e all thinking: 鈥榝inally.鈥欌��

The spacecraft is about the size of a small cooler. But it has hefty goals: over the course of a year, the roughly $3 million satellite will circle Earth to observe radiation from the sun and how it influences the planet's听atmosphere.听

INSPIRESat-1 marks the flagship mission of the (INSPIRE). This coalition of 11 universities from Canada to Singapore brings together undergraduate and graduate students to get hands-on experience in designing spacecraft鈥攂uilding satellites that collect real scientific data in space. The roughly 30 students on the INSPIRESat-1 team experienced a lot of late nights, around-the-world flights and Zoom calls before Zoom calls were the norm. They cooked their regional dishes for each other, played soccer and, in some cases, saw snow for the first time in the Rocky Mountains.听

鈥淚t was a cross-cultural experience,鈥� said Amal Chandran, the program manager for INSPIRE at LASP. 鈥淲e鈥檙e bringing together students who are going to be the leaders of the space community in the future. We want to engrain in them that working collaboratively is a good thing.鈥�

Six universities collaborated on INSPIRESat-1, including 欧美口爆视频 Boulder, the Indian Institute for Space Science and Technology (IIST), Nanyang Technological University (NTU) in Singapore, National Central University (N欧美口爆视频) in Taiwan, the University of Alberta in Canada and Sultan Qaboos University in Oman. The mission was funded, in part, by a grant from 欧美口爆视频 Boulder Provost Russell Moore.

鈥淚NSPIRE has given students from around the world new opportunities to work collaboratively in international听teams to develop real spacecraft from the idea stage to launch and beyond,鈥� Moore said. 鈥淭he program shows 欧美口爆视频 Boulder鈥檚 commitment with providing students with hands-on research experiences that will allow them to become the scientific and engineering leaders of the future.鈥�

Out in the snow

The global team of students behind INSPIRESat-1 aren鈥檛 just top-notch scientists and engineers鈥攖hey also represent the future of space exploration. By the end of the decade, Chandran estimates that as many as 50 new countries could launch their first satellites into space.听

鈥淪pace is going international,鈥� said Chandran who also leads the Satellite Research Centre at NTU. 鈥淲hat we want to do at LASP is teach these new entrants into space听how to create a sustainable space industry by supporting high-quality research.鈥�

Daniel Baker, director of LASP, agreed.

"Small spacecraft are revolutionizing how space research is done, and the INSPIRE program has been changing how young people from around the Earth see themselves and what they can contribute to understanding our planet,鈥� he said. 鈥淲e are pleased that INSPIRESat-1 is ready to go into space. With it go the aspirations of students and institutions that see a bright future in space exploration.鈥�

Duann Yi joined the INSPIRE team in 2017, when she was pursuing her master鈥檚 degree at N欧美口爆视频 in Taoyuan City, Taiwan. She traveled to the United States three times for the project鈥攐ver the summers in 2017 and 2018 and for eight months in 2019.

鈥淭he views in Boulder are really beautiful, and the people there are really nice,鈥� said Yi, now a doctoral student at N欧美口爆视频.

Sarthak Srivastava, who started on INSPIRE while working as a research engineer at NTU, said that CubeSats are the perfect sandboxes for learning about spacecraft. When your satellite is that small, you have to know how every component and subsystem works.听

鈥淕iven the lean teams and smaller scale of such projects, very often we get involved in technical work very different from our area of expertise,鈥� said Srivastava, now a doctoral student.

INSPIRESat-1 boasts two scientific instruments in one small package. The (DAXSS), developed by LASP, will look outward, collecting data on X-ray radiation emanating from the sun. The Compact Ionospheric Probe (CIP), developed by N欧美口爆视频, will point down to measure fluctuations in Earth鈥檚 ionosphere鈥攐r the highest layer of the atmosphere beginning about 50 miles above the planet鈥檚 surface.

Boyajian noted that the cross-cultural aspect of the project wasn鈥檛 always easy. The students had to overcome big cultural and language barriers to function as a team. But they also had fun together, both in and out of the lab. One summer, he took a group of students to St. Mary鈥檚 Glacier to the southwest of Boulder where they slipped and played in the snow.听

鈥淎t the end of the day, we鈥檙e all nerds,鈥� said Boyajian.

First contact

Now, they鈥檙e counting down the hours until INSPIRESat-1 finally launches. Once it makes it to space, Boyajian explained, the CubeSat will push off from its rocket to enter into orbit around Earth. The team will then have to scramble, using satellite antennas on the ground to try to locate the spacecraft鈥檚 faint radio signal above.听

鈥淥ur orbit is going to fall within a slim trajectory, but space is big,鈥� he said. 鈥淭he stress won鈥檛 abate until we get that first contact.鈥�

When that first contact comes, however, Yi said students across many different countries will have reason to celebrate:听鈥淭here is always a sense of achievement to see something you worked on for so long go up into orbit.鈥�
