Isro plans to conduct an unmanned mission as part of Gaganyaan before abort tests on the test vehicle.

 The first unmanned mission may occur before the abort tests, but abort missions are only required for crewed missions.

The first unmanned mission will exclude the service module, but the semi-humanoid Vyomitra may be included.

ISRO has set a goal to launch at least one unmanned mission by the beginning of the first half of the year 2024.

The first uncrewed mission could be carried out separately from the planned abort tests on the special test vehicle.

When the first unmanned mission is carried out, the service module will not be included.

Critical Gaganyaan technologies will enable more advanced orbital modules and long-term human space presence technology

 The uncrewed flights serve as initial steps to evaluate different technologies for the crewed Gaganyaan mission.
