Space science in Indonesia has made a lot of developments. One of them was the successful launch of LAPAN-A2/ORARI satellite on September 28, 2015 with an expected life time of about 2 years. The satellite is the second micro satellite launched by LAPAN with the weight of 78 kg. The satellite has a low orbit, at an altitude of 650 km. The launch was conducted in India with an Astrosat satellite <br /> <br /> as the main load. The LAPAN-A2/ORARI satellite is used for Earth monitoring, maritime monitoring and for disaster mitigation missions. <br /> <br /> The launch of satellites is not arbitrary given the fact that there are currently 700,000 pieces of space debris that have been tracked from the existence of their orbits. The space debris is generated from spacecraft launched from Earth and has exhausted its lifetime so that it does not carry out its mission again. Starting from the process of launching, placement and behavior in orbit, until treatment after its life runs out, overseen by a space law called the International Space Law, which is coordinated by <br /> <br /> the UN agency. The national space law applicable in Indonesia since 2013 on space activity is Undang-undang Keantariksaan No. 21 year 2013. <br /> <br /> The research is to know the compliance of satellite LAPAN A2/ORARI, whether it is in accordance with the applicable space law or not by using Debris Assessment Software (DAS) 2.0 built by NASA. Then perform a qualitative analysis of satellite assessment using space law and predict the behavior of satellite orbitals after their lifetime. <br /> <br /> The results obtained from this research are for the end of the life time of LAPAN A2/ORARI satellite in 2043. This means that the orbit is 28 years old. This value has a small difference with applicable DAS 2.0 criteria of maximum 25 years life long, so it can be tolerated. The impact of the resulting debris will increase over <br /> <br /> time. The amount of impact of debris tends to be large on objects that have small diameter. This is quite dangerous for satellites because if the velocity is too big, it can damage the performance of the satellite. From the results of the analysis, we can prepare what things will be done to prevent the possibility of negative impact from space debris generated from LAPAN-A2/ORARI satellite. Given the incident that happened to Madura in September 2016 ago, related to the fall of waste Falcon 9 rocket, although not claimed casualties but it was dangerous re-entry. <br /> <br /> With this research, we find that in general, the LAPAN-A2/ORARI satellites are in compliance with existing space laws.
