Nepal Sat – 1, the first satellite developed and launched by Nepal on space two years back, is approaching its final days soon. The satellite was sent from ISS (International Space Station) in June 2019 on lower space earth orbit at around 450 km from Earth, which completes its rotation in 1.5 hrs. It has completed 11,400 rounds of the earth in two year’s period. The cube shaped nano satellite having nearly 1 kilo gram of weight was launched two years ago with its four missions. It will turn into ashes in nearly 2-3 months period, according to scientist at NAST Roshan Pandey, who is involved in monitoring ground station of the satellite from NAST for the past two years.
The NAST- Nepal and Kyu-Tech Japan collaboration project was initiated with great hope keeping in mind future research activities. The nano satellite was developed by a team of scientists including Avash Maskey, who were studying in the Japanese University. Though research part of the project was not that satisfactory, it has obviously generated some interest among the youths regarding space exploration. In fact, the satellite was just the research output for study purposes, which was manipulated in another way as big satellite mission.
The four missions of the project include: LRa Demonstration Mission (LDM), imaging Mission (CAM), Attitude Determination and Control Mission (ADCS) and Software Configurable Backplane Mission (BPB).
NepalSat – 1 was launched with four missions as birds- 3 project along with Sri Lanka and Japan. Such types of satellites has the life of 2/3 years maximum and as it comes closer to earth gradually and with strong gravitational pull around 350/320 km it maoves with greater speed to have friction withi air and vanishes before reaching the ground. NepalSat-1 will also have same pattern in coming days. Better collaboration norms with international agencies and clear research mission could be best possible solution for contributing in such advanced joint activities.
