## 1 Introduction  
Over the past few decades, it has become increasingly evident that Outer Space is central to humankind's present-day functioning, as well as its future. The amount of activity by both States and private actors in Outer Space is constantly escalating, with reliance on the services and opportunities that it provides ever-growing.  
An example would be the internet and communications that are essential to the regular use of technology, which is all facilitated by satellites in the various orbits around Earth. While the use of high-speed internet has propelled development forward where the existing satellites render it available, a proportion of the Earth's population does not have access to such facilities and could greatly benefit from them--which is one of the reasons behind the need for the launch of more satellites.  
However, the benefits that could be attained from an increased number of satellites, and proposed satellite mega-constellations in Outer Space, also pose a risk to one of the oldest practices associated with Outer Space itself--that of astronomy. While the viewing of the night sky is a practice enjoyed, both professionally and recreationally, by many of humankind, astronomy also constitutes a central practice in the way of life and sense of being of many Indigenous Peoples. The constant addition of satellites into orbits around Earth threatens the night sky and, in doing so, threatens the Indigenous practice of many peoples and the possibility to transfer Indigenous knowledge inter-generationally through that practice.  
Thus, while benefits can be achieved for some of humankind by increasing the number of satellites currently in Outer Space, moving forward with these plans should be regulated and designed with input from Indigenous parties who have knowledge on the maintenance of a sustainable relationship with Earth and Sky that arguably could contribute towards greater sustainability in the approaches currently being taken towards Outer Space.  
This article aims to investigate, by adopting a descriptive-normative research methodology, the plans for satellite mega-constellations, the impact that these constellations have on astronomical practices and following on from this, the threats that satellite constellations pose to Indigenous astronomy and knowledge. Grounded in this research, this article will then propose recommendations for how Indigenous voices could be better included in decisions made with respect to the approval of plans for satellite mega-constellations. The inclusion of Indigenous voices into decision-making processes is important because Indigenous astronomical knowledge is central to the continuation of Indigenous knowledge systems that long pre-date the creation of satellites by humankind. Any threat to these knowledge systems requires attention. The threat currently posed by satellite mega-constellations to Indigenous astronomy arguably exists as a result of planning in the absence of consideration for all relevant interest-holders, which, as this article will establish, includes Indigenous Peoples and should be rectified through the inclusion of Indigenous voices by means of the avenues that this article will propose.
