6S CubeSat

6S is 1U CubeSat that will be the first satellite entirely designed and built by students of Politecnico di Milano.

Our goal is to provide an opportunity to get hands-on experience and apply knowledge about mission and subsystems design in practice. We are also creating network with external parties, as the team meets with interested companies, securing not only components or sponsorships, but also future jobs.

6S Payloads

5

Testing of perovskite solar cells

Test of postage-cards new generation solar cells.

They have:

  • High efficiency
  • High specific power (i.e. power to weight ratio)
  • Excellent radiation resistance

Design challenges:

  • The mission requires measuring the following quantities:
  • Voltage
  • Current
  • Temperature
  • Light intensity on the external surface
6

Technology demonstration of green propellant thruster - SteamJet

It is a prototype of water-based miniaturized electro-thermal thruster.

The system can be stored partially in the tunacan (fitting inside the coil spring of the CubeSat deployer mechanism)

We would like to prove station-keeping and de-orbit maneuvers for a CubeSat

Design challenges:

  • Volume constraints
  • Power draw
  • Pointing accuracy
4

Structural battery testing – VoltaStructural

It is a rigid sandwich panel that acts as a battery and can carry loads at the same time

The battery can be both planar and curved.

Design challenges:

  • Very low TRL (only demonstrated)
  • Careful thermal control
  • Outgassing & space debris
