00:00This is our system architecture. On the left side you see the spacecraft and on the right side you see
00:07the ground segment.
00:09We actually partner with Delta V. They are developing the hybrid propulsion system but the rest of the mission we
00:15are responsible as Tribute Guzai.
00:17And we designed a modular spacecraft as I mentioned.
00:21We have on the bottom we have the propulsion module. In the propulsion module we have two propulsion systems.
00:27And we also had presentations of these systems.
00:32So we have bipropalant chemical propulsion system and the hybrid propulsion system in the middle.
00:38And platform module is actually like a satellite.
00:42So we have all the subsystems and plus the payloads. They are mainly located on the top of the spacecraft.
00:48And this side will be the moon facing side.
00:51And on the ground segment part we have ground station network that we will access to geographically distributed ground station
00:59antennas.
01:01But we will control them from the operation center that is located in Ankara.
01:06So in terms of technology demonstrations we have, as I said, mission-based navigation system to determine position and altitude
01:14using lunar surface images.
01:16And we have hybrid propulsion system developed by Delta V.
01:20So it uses nitrous oxide as an oxidizer and polymeric solid as a fuel.
01:27And maximum thrust is 700 newton.
01:30And average thrust we will have 650 newtons.
01:34And we are planning to fire this thruster twice.
01:39One in Earth orbit and one in lunar orbit depending on the operational conditions.
01:44That's a very good question.
01:46So we are not, currently we are not only working for TLM1.
01:52We work on TLM, for TLM1 officially.
01:56But we also work for TLM2 not officially.
02:01So what we did is maybe some of our scholarship students are here too.
02:07In this project we had many scholarship students.
02:10And with these students we studied the TLM2 concepts.
02:15For example, we designed rover, conceptual rover.
02:18We made conceptual rover design.
02:20We designed lander.
02:22We designed lander propulsion system architecture and also some simulations.
02:28We designed what to do with the rover too.
02:31For example, what kind of experiment we should do in the lunar surface.
02:36It could be, for example, strategic capabilities in terms of resource utilization, resource identification.
02:43So our students studied all those.
02:45So we, at the same time, we prepared our, let's say, young colleagues for the next missions too.
02:54So they did several studies in that sense.
02:56And we also published in IACs as well.
02:59Thank you very much.
03:01And I respect a lot what you are doing in our mission.
03:07We are working all together.
03:08And thanks for your effort at first.
03:11My question is that actually I really wonder about the most challenges part of the spacecraft mission,
03:20excluding from designing and manufacturing part of the components.
03:24Thank you.
03:25Which you were responsible, right?
03:26From some part.
03:28So, structure?
03:29Or, no.
03:31Yes, there are several difficulties we had over the design of the spacecraft.
03:37First of all, communication.
03:39We use our own systems, S-PAN and X-PAN systems.
03:44And we actually started to have two S-PAN transponders that is developed by us.
03:49But in the meantime, we decided, okay, maybe we should have a flight redundant S-PAN transponder with a flight
03:57heritage.
03:58So we procured one of them.
04:01So we procured one of them.
04:01So communication is one.
04:02The second is thermal environment is, seems to be very difficult.
04:08It seems to be, we will have some difficulties in terms of thermal environment.
04:11And we had a very tough time to identify worst-case scenarios and to save our spacecraft against this worst
04:19-case scenarios.
04:20The placement of the equipment in terms of thermal design was also very challenging.
04:25And the structures of the equipment in terms of thermal design was also very challenging.
04:26And the structure of the equipment.
