The Philippine Space Agency (PhilSA) recently confirmed that debris recovered in Bataan a month ago is highly likely to be from a Chinese rocket, indicating a concerning space event. Following an investigation conducted by the PhilSA, experts have concluded that the recovered debris shares distinct characteristics with components used in Chinese rockets. The findings strongly suggest that the remnants originated from a Chinese launch vehicle.
This discovery raises questions regarding the responsible management of space activities and has prompted concerns about the safety and potential hazards associated with space activities. With the ever-increasing number of space missions being conducted by various countries, ensuring responsible practices and proper disposal of debris has become crucial.
The PhilSA, in collaboration with international space agencies, is closely monitoring space events to mitigate such risks and prevent future occurrences. Established in 2019 and operational by 2020, the PhilSA has been actively addressing the challenges of space sustainability. The agency emphasizes the importance of responsible space exploration and the need for international cooperation in maintaining the sustainability of outer space.
The recovery of this debris serves as a reminder of the significance of space situational awareness and the urgent need to address the challenges posed by space debris. PhilSA remains committed to promoting scientific research, technological advancements, and international collaboration to ensure the peaceful and sustainable use of outer space.
In a conversation with Geospatial World, Noelle Riza Castillo, Director of the Space Policy and International Cooperation Bureau at the PhilSA, emphasized the significance of mitigating and managing space debris. As a lawyer by profession, Castillo joined the PhilSA in 2021 and has been at the forefront of the country’s space exploration endeavours.
Castillo highlighted the urgent need for appropriate guidelines to effectively respond to space debris resulting from foreign rocket launches.
Establishing National Protocols for Space Debris Management
In 2021, the agency formed a Technical Working Group on Orbital Debris Protocols. This advisory body focuses on coordinating discussions, formulating strategies, and integrating guidelines for orbital debris in the Philippine space region. The group comprises the PhilSA, local government authorities, Navy, and Air Force, each with its own set of protocols. By coordinating efforts, these agencies can effectively respond to emergencies and minimize the impact on affected communities.
One of the key priorities is the implementation of space object registration. Efforts are underway to raise awareness and encourage all countries to register their space objects with the United Nations (UN), ensuring transparency regarding satellite ownership, status, and usage. Another significant concern is the growing problem of space debris.
“In recent times, space debris has been falling into the Philippine seas, and they have been discovered by our fishermen in fishing waters near our communities. As a nation, we have responded domestically by creating a multi-agency task force or working group to address these situations,” said Castillo.
While the Philippines is not yet a spacefaring nation, it has satellites in orbit. The debris from rocket launches, primarily from China, often falls into Philippine seas and is discovered by local fishermen. In response to this domestic challenge, the PhilSA has established a multi-agency task force and working group on Orbital Debris Protocols. The aim is to develop national protocols on how to respond to these situations effectively.
Coordinated Efforts to Safeguard Philippine Territories and Communities
Considering the archipelagic nature of the Philippines, where debris can potentially fall on any of the country’s 7,000+ islands, a coordinated approach involving local governments, aviation authorities, and the space agency is crucial. To enhance response capabilities, the PhilSA has been collaborating with various stakeholders to create unified guidelines.
However, one of the major obstacles lies in being aware of rocket launches in advance, as notifications are often insufficient or provided on short notice. Efforts are being made to decipher launch information through civil aviation notice data or format.
Regarding the local population, including fishermen in affected areas, the PhilSA strives to inform them promptly once a rocket launch is detected. This includes plotting the projected debris path and communicating the potential impact to communities. However, Castillo emphasized the importance of transparency on the part of launching states to prevent such incidents.
“There is a need to coordinate with each other on how to respond as soon as we become aware of a rocket launch that will pass through our territory. The current challenge lies in obtaining awareness of the rocket launch since the notices are not being provided transparently,” said Castillo.
By manoeuvring spacecraft away from local communities, the risk of debris falling on inhabited areas can be significantly reduced.
As space becomes more congested with satellites and the influx of new space players, the PhilSA remains committed to keeping the local population informed about potential risks. Immediate communication with communities is essential, and the agency’s technical working group plays a vital role in disseminating critical information. By analyzing debris trajectories and identifying areas at risk, the PhilSA strives to ensure the safety of its citizens.
The efforts and initiatives undertaken by the PhilSA reflect its commitment to addressing the challenges of space debris and ensuring sustainable practices in the country’s growing space industry. Through collaboration, coordination, and the formulation of comprehensive protocols, the agency is taking proactive steps to protect its territories and communities from the hazards associated with space debris.
