India does not launch to start with tiny satellite “SSLV” rocket focusing on large frequency and lower charge | internet site of the portal sorae in space

The Indian Room Analysis Group (ISRO) declared on August 7 that the new rocket “SSLV (Small Satellite Start Vehicle)”Was launched for the to start with time. Despite the fact that the rocket flew in fifty percent as planned, the burnup ended earlier than expected in the final phase, so the satellite could not be put in the ideal orbit.

SSLV made by ISRO was released in South India on August 7, 2022 at 12:48 Japan time.Satish Dhawan Place Centerwas released from Just after the 1st phase was divided about two minutes soon after launch, the second and 3rd stages ended up separated as planned. Nevertheless, about 10 minutes soon after the launch, the football period was on.VTM (Speed ​​cutting module)‘the motor straight away stopped burning.

A handful of hrs later, ISRO introduced a statement stating that the onboard satellite had been placed in an elliptical orbit at an altitude of 76 x 356 km alternatively of the planned round orbit at an altitude of 356 km. The cause is claimed to be a malfunction that happened in the VTM and the satellite is considered to have been misplaced right after re-getting into the ambiance. S. Somanath, head of the ISRO business, said:Up to the third phase of the rocket it labored as predicted.“, and in the last stage,”lost info‘ She explained.

SSLV isRecurrent and very low-price launch of tiny satellites and microsatellitesIt is a 34 m prolonged 3-phase good propellant rocket (makes use of hydroxyl terminated polybutadiene as gas) developed with the intention of attaining the goal of launching a satellite weighing 500 kg into minimal Earth orbit at a single altitude of 500 km. In addition, to set the satellite into orbit as meant, the VTM kick phase is geared up with a liquid fuel rocket motor (employing monomethylhydrazine and dinitrogen tetroxide added with nitrous oxide).

Secondo il media di sviluppo spaziale d’oltremare SpaceNews, lo sviluppo di SSLV è iniziato nel 2017 e il piano iniziale doveva essere lanciato nel 2019. Tuttavia, il programma è stato ritardato a causa del fallimento del test di combustione condotto nel 2021 e della stagnazione dell’industria spaziale a causa dell’epidemia del nuovo contagio da coronavirus.

Inoltre, l’SSV lanciato questa volta ha un satellite per l’osservazione della terra “EOS-02” e CubeSats “AzzadiSAT” è stato installato. EOS-02 è un satellite sperimentale di telerilevamento ottico con un peso di 135 kg sviluppato da ISRO. AzzadiSAT è un CubeSat da 8 kg (dimensione 8U) sviluppato da uno studente indiano, ed è stato dotato di un totale di 75 carichi utili (ciascuno del peso di circa 50 g), tra cui un transponder UHF-VHF, un rilevatore di radiazioni e una selfie camera. significare.
