Satélite de Reentrada Atmosférica
SARA - Satélite de Reentrada Atmosférica is a Brazilian satellite project,[1] with the objective of performing experiments in microgravity environment and returning them to the Earth.[2]
SARA Suborbital
The proposed flight schedule includes a first sub-orbital test flight (SARA Suborbital 1) in 2014[3][4] using a VS-40 rocket launched from the Centro de Lançamento da Barreira do Inferno (Operação São Lourenço).[4] The predicted apogee is 350 km with a range of 300 km. Time spent in microgravity will be around 8 minutes, after which the satellite will reenter the atmosphere and be recovered at sea, 100 km out from Parnaíba.
A second suborbital flight is planned (SARA Suborbital 2), to test flight attitude control system and de-orbit engine.
Configuration
The "Sara suborbital" platform heights 350 kg and is divided into four subsystems:
- Structural
- Electrical - includes cold gas actuators, designed to null the satellite's angular velocity after launch
- Recovery - 3 parachutes: pilot, drogue and main
- Experiment module (MEXP)
SARA Orbital
The orbital version of the satellite will operate in a circular 300 km low earth orbit, during a maximum of 10 days. There is a report that the VS-40 launcher with the SARA re-entry vehicle exploded on the launch pad this morning November 13, 2015. Fortunately there were no injuries nor fatalities.
