+ASSISTANT: A detailed design for a future CMB satellite would involve several key components. Firstly, the
+choice of detector technology is crucial. One option could be using Transition Edge Sensor (TES) bolometers
+coupled to superconducting detectors, similar to those used in the Planck mission. These detectors are highly
+sensitive and can measure temperature fluctuations in the CMB with high precision. Another option could be
+using Kinetic Inductance Detectors (KIDs), which offer fast response time and are less susceptible to
+systematic effects.
+
+Next, the optics design should aim to minimize stray light and ensure high optical efficiency. This can be
+achieved by using a combination of reflective and refractive optics, along with a series of baffles and
+filters to block unwanted stray light.
+
+The choice between a photometer and a spectrometer depends on the science goals of the mission. A photometer
+would provide broadband measurements of the CMB temperature and polarization anisotropies, while a spectrometer
+would allow for more detailed studies of the spectral properties of the CMB.
+
+Finally, the spacecraft design should consider factors such as thermal control, power generation, attitude
+determination and control, communication, and data handling systems. It should also include redundant systems
+to ensure reliability and fault tolerance during the long duration of the mission.
