Launch of SSLV-D2/EOS-07 Set for February 10th from Sriharikota
The next launch of the Small Satellite Launch Vehicle (SSLV-D2) with the Earth Observation Satellite (EOS-07) and two other satellites as part of its payload is scheduled to occur on February 10 from the Sriharikota spaceport. Chennai is where the event will take place.
This Friday, the Indian Space Research Organisation (ISRO) has announced that the SSLV-D2 will be launched from the First Launch Pad shortly after 9:18 a.m.
A total mass of 334 kg, including EOS-07 satellite and two other accompanying satellites, is expected to be delivered by the SSLV-D2.
The satellite will be placed in a Circular Low Earth Orbit with an altitude of 450 km and an inclination of 37.2 Deg to the equator.
The SSLV is developed to be reasonably priced and suitable for industrial production and serve as a launch-on-demand support for Mini, Micro or Nano satellites. It is a three-stage rocket with all solid propellant stages and a Velocity Trimming Module (VTM) powered by liquid propulsion as the terminal stage.
This launcher aims to provide several unique functionalities, such as fast turnaround times, the capacity to carry multiple satellites, the ability to launch on request, and minimal infrastructure needs.
On August 7, 2020, the initial trial launch of the SSLV-D1/E0S-02 was unsuccessful.
The aim of the mission was to place the EOS-02 satellite in an orbit with a circumference of 356.2 km and an inclination of 37.21 Deg, and to also deliver Azaadisat, a student satellite.
Despite the solid propulsion stages performing normally, the spacecraft were put into an extremely elongated and unstable orbit because of the lack of speed, causing them to quickly fall from the sky and reenter the atmosphere.
The satellite was put into an orbit of 360.56 km x 75.66 km and tilted at an angle of 36.56 degrees. Preliminary assessments of the data from the launch indicated that the SSLV D1 lift-off was normal and all solid rocket stages operated as expected.
Though the mission was not successful, an issue during the detachment of the second stage (SS2) caused it to shift into a mission salvage mode. This method is used to attempt to keep the Spacecraft in a stable orbit whenever a malfunction of the vehicle occurs.
The reasons for the breakdown were investigated by ISRO's Failure Analysis Committee (FAC) who concluded that vibration occurred for a limited period of time, leading to the malfunction.
The Flight Acceptance Committee's report stated that a thorough analysis of the flight events - from the countdown, launch, propulsion performance, and satellite injection - revealed a vibration anomaly on the Equipment Bay deck for a brief period during the SS2 separation. The Inertial Navigation System determined the sensors were faulty due to the Fault Detection & Isolation software
The SSLV-D2 is being conducted in accordance with the recommendations given for the flight anomaly after it has been accurately identified. Furthermore, its execution is satisfactory and has been reviewed and authorized by the necessary committees.

Rajasthan tanker fire: Death toll rises to 19 as man succumbs to burns
Jaipur (PTI): The death toll in a tanker-fire incident in Rajasthan has gone up to 19 with another man succumbing to his severe burn injuries at the Sawai Man Singh (SMS) hospital here on Thursday.
SMS hospital superintendent Dr Sushil Bhati informed that one more death was recorded on Thursday, taking the total number of fatalities in the horrific incident to 19. "Currently, 11 people are undergoing treatment at the hospital," he said, adding that two or three of them are likely to be discharged on Thursday.
Lalaram (28), who died on Thursday, had 60-per cent burn injuries and was on a ventilator. Three more patients are on ventilator support. The body has been shifted to the hospital's mortuary for post-mortem. Lalaram's friend Ramavtar said the victim was a security guard in an IT company at the Mahindra SEZ. He was on his way to work on a motorcycle when he got trapped in the fire.
"He had a morning shift that day. He was a resident of Sanganer but had shifted to the Kanota area on the Agra highway sometime ago. He was on a motorcycle when the incident happened," Ramavtar said.
The victim was unmarried. Three people, who sustained injuries in the incident, died on Wednesday. An LPG tanker collided with a truck on December 20, sparking a massive fireball that turned a stretch of the Jaipur-Ajmer highway into an inferno. Eleven people had died on the day of the incident and four had succumbed to their injuries subsequently.
