The Japan Aerospace Exploration Agency (JAXA) launched the Innovative Satellite Technology Demonstration-2 (ISTD-2) on February 28, 2019, to showcase advanced satellite technologies and demonstrate their potential for future space missions. In this essay, we will discuss the launching date, the reasons behind the mission, how it was carried out, the estimated cost, and the achievements of the ISTD-2 mission.

Launching Date:

JAXA launched the ISTD-2 mission on February 28, 2019, using an H-IIA rocket from the Tanegashima Space Center in Japan. The launch was originally scheduled for January 17, 2019, but it was postponed due to bad weather conditions.

Reasons for the Mission:

The ISTD-2 mission was designed to demonstrate advanced satellite technologies and their potential for future space missions. The mission was intended to showcase various technologies such as autonomous orbit determination and control, advanced power generation and storage systems, and high-performance communication systems.

The mission also aimed to test new technologies such as the small and high-efficiency solar cells, the innovative propulsion system, and the ultra-high-speed data transmission system. These new technologies have the potential to revolutionize future space missions and enable new scientific discoveries.

How it was Carried Out:

The ISTD-2 mission was carried out using the Small Demonstration Satellite-4 (SDS-4), which was designed and built by JAXA. The SDS-4 is a small satellite weighing approximately 570 kg and measures 1.7 m x 1.6 m x 2.1 m. The satellite was launched into a sun-synchronous orbit at an altitude of approximately 600 km.

The SDS-4 was equipped with several advanced technologies, including autonomous orbit determination and control, a high-performance communication system, and advanced power generation and storage systems. The satellite also had a propulsion system that used an innovative micro-electro-mechanical system (MEMS) thruster to control its attitude and orbit.

During the mission, JAXA conducted several tests to demonstrate the performance of the satellite's advanced technologies. The tests included a demonstration of the autonomous orbit determination and control system, a test of the ultra-high-speed data transmission system, and a demonstration of the innovative propulsion system.

Estimated Cost:

The estimated cost of the ISTD-2 mission has not been publicly disclosed by JAXA. However, it is believed to have cost several million dollars, considering the advanced technologies that were tested and the complexity of the mission.

Achievements:

The ISTD-2 mission achieved several significant milestones, including the successful demonstration of several advanced technologies. Some of the key achievements of the mission are as follows:

Successful Demonstration of Autonomous Orbit Determination and Control System:

One of the main objectives of the ISTD-2 mission was to demonstrate the performance of an autonomous orbit determination and control system. The system was designed to enable the satellite to maintain its orbit without the need for ground-based commands.

The system was successfully demonstrated during the mission, and the satellite was able to maintain its orbit using its onboard sensors and algorithms. This achievement represents a significant step forward in the development of autonomous spacecraft.

Successful Test of Ultra-High-Speed Data Transmission System:

Another key objective of the ISTD-2 mission was to test an ultra-high-speed data transmission system. The system was designed to enable the satellite to transmit large amounts of data back to Earth at high speeds.

During the mission, JAXA successfully tested the data transmission system, demonstrating that it could transmit data at speeds of up to 1 Gbps. This achievement represents a significant improvement over existing data transmission systems and could enable new scientific discoveries in the future.

Successful Demonstration of Innovative Propulsion System: 

The ISTD-2 mission also successfully demonstrated an innovative propulsion system using a micro-electro-mechanical system (MEMS) thruster. The MEMS thruster is a tiny device that uses electricity to produce thrust and control the attitude and orbit of the satellite.

During the mission, JAXA demonstrated the performance of the MEMS thruster, showing that it was capable of precise and stable control of the satellite's attitude and orbit. This technology has the potential to enable new types of space missions, including small satellite missions that require precise orbit control.

Successful Demonstration of Advanced Power Generation and Storage Systems:

The ISTD-2 mission also demonstrated advanced power generation and storage systems, including small and high-efficiency solar cells and lithium-ion batteries. These systems were designed to enable the satellite to operate for extended periods of time in space.

During the mission, JAXA demonstrated the performance of the power generation and storage systems, showing that they were capable of providing a stable and reliable source of power to the satellite. This achievement represents a significant step forward in the development of advanced power systems for space missions.

In conclusion, the ISTD-2 mission was a successful demonstration of several advanced satellite technologies and their potential for future space missions. The mission achieved several significant milestones, including the successful demonstration of autonomous orbit determination and control, ultra-high-speed data transmission, innovative propulsion systems, and advanced power generation and storage systems. These achievements represent a significant step forward in the development of advanced satellite technologies and could enable new types of space missions in the future.
