The following is a possible concise summary of the transcript:
This is a transcript of the live telecast of the maiden launch of the small satellite launch vehicle (SSLV) D1 mission from the Satish Dhawan Space Center in Sriharikota, India. The mission aims to put two satellites, EOS02 and Azadi Sat, into a 356.2 kilometers circular orbit. The transcript describes the launch sequence, the features and performance of the SSLV stages, the tracking network, and the payload fairing separation. The transcript also includes some announcements from the range operations director and the mission director, who authorizes the launch and initiates the automatic launch sequence. The transcript ends with a brief speech from the mission director, who says that there was some data loss in the terminal phase of the mission and that they are analyzing the data to determine the final outcome of the mission. He thanks the viewers for their patience and interest in the launch.
1. The launch of the Small Satellite Launch Vehicle (SSLV) is scheduled for today, the 7th of August 2022, at 9:18 hours Indian Standard Time. The launch is taking place from the first launch pad .
2. The SSLV mission aims to put the primary satellite EOS02, weighing 135 kgs, into a 356.2-kilometer circular orbit. It also carries a co-passenger satellite Azadi Sat weighing 9.4 kgs in the same orbit .
3. The SSLV is fully ready for its maiden mission .
4. The SSLV design emphasizes integration and test simplicity. It is noted that "bigger is not always better" and "heavier is not always more powerful" .
5. The SSLV has a design that allows for flexibility in accommodating multiple satellites. It requires minimal launch infrastructure compared to other launch vehicles .
6. The SSLV is an effective solution for payloads that were previously launched as secondary payloads on medium launch vehicles .
7. The SSLV campaign for the D1 mission lasted for a mere seven days .
8. The SSLV is powered by 87 tons of HDPB-based solid propellant .
9. The SSLV is 34 meters tall, 2 meters in diameter, and has a lift-off mass of about 120 tons .
10. The SSLV is tracked during the flight by the ISRO telemetry tracking and command network .
