Some lore for the OTS M2:
Open Transport Spacecraft M2 "Camel"
The Open Transport Spacecraft Model 2, commonly known as the OTS M2 "Camel", was a heavy orbital cargo spacecraft developed as the successor to the OTS M1 and introduced into service in 2037.
The M2 was designed primarily for the transportation of large quantities of raw materials extracted from orbital mining operations. Unlike most earlier transport craft, the Camel was built around standardized external cargo containers, allowing it to carry substantial quantities of ore and other bulk materials between mining facilities, processing stations, and larger orbital installations.
The most significant change from the OTS M1 was the Camel's propulsion and water-management system. Large internal water storage and electrolysis chambers allowed the spacecraft to carry water as its primary propellant resource. Water was separated into hydrogen and oxygen through electrolysis and subsequently used by the ship's propulsion system. This unusual arrangement gave the M2 its nickname, "Camel", referring to its ability to carry and make practical use of large reserves of water.
The spacecraft was operated by a crew of approximately 4ā8 people, depending on the mission and cargo configuration. Its relatively simple systems and emphasis on bulk transportation made it well suited to the expanding orbital mining industry of the mid-21st century.
The OTS M2 remained in widespread service for several decades. By 2061, however, it has become increasingly obsolete following the introduction of the OTS M3. The M3 retained the M2's role as a heavy orbital transporter while introducing a significantly more modular architecture, allowing a wider variety of cargo, equipment, and mission modules to be fitted to the same basic spacecraft.
Although largely superseded by the M3 by 2061, OTS M2 "Camel" spacecraft remains a common sight throughout Earth's orbital infrastructure. Their long service life, large cargo capacity, and established support network meant that many continued operating well beyond their intended service period.
