India’s PSLV rocket launches nine satellites on last mission of 2022

SEOUL, South Korea — India’s ISRO space agency launched a one-tonne Earth observation satellite and eight nanosatellites into sun-synchronous polar orbit on Nov. 26 aboard the nation’s Polar Satellite Launch Vehicle (PSLV).

The rocket took off from the Satish Dhawan Space Center at 1:26 a.m. Eastern Time. The launch was streamed live on YouTube, which showed the 44-meter rocket lifting off with a brilliant flame projected from its first-stage booster and rising into the sky. The main payload, EOS-06, separated from the rocket’s upper stage about 17 minutes after liftoff at an altitude of 742 kilometers. The other satellites were deployed between 114 and 125 minutes after takeoff.

ISRO President S. Somnath said the mission was a success in a speech conducted approximately two hours after launch. “I’m really happy to report the success of the PSLV-C54/EOS-06 mission,” said the president. “We also observed that the performance of the rocket in this mission in all its stages and functions was extremely good.”

EOS-06 is India’s Oceansat series third-generation Earth observation satellite, designed to provide “Oceansat-2 spacecraft continuity services with improved payload specifications as well as application,” according to ISRO. pre-launch document of the mission. The spacecraft has four payloads: an Ocean Color Monitor (OCM-3); sea ​​surface temperature monitor (SSTM); Ku-band scatterometer (SCAT-3); and ARGOS, a French payload intended to reinforce the existing fleet of Indo-French meteorological satellites.

Secondary payloads include the ISRO-2 Nano-Satellite for Bhutan (INS-2B), which will have two payloads, namely NanoMx and APRS-Digipeter. NanoMx is a multispectral optical imaging payload.

The November 26 launch was ISRO’s fifth and final mission for 2022. The first mission in February put three satellites into low earth orbit aboard a PSLV rocket, followed by the launch of three satellites in June aboard a PSLV, the failed maiden flight of the Small Satellite Launch Vehicle (SSLV) in August, and the successful launch of the 36 OneWeb satellites in October aboard a geosynchronous satellite launcher (GSLV) Mark 3. It was the 56th flight of the PSLV since its commissioning in 1993, according to ISRO.

Meanwhile, the Indian startup Skyroot Aerospace launched the country’s first private rocket, Vikram-S, November 18 from the Satish Dhawan Space Center in Sriharikota. It was a suborbital launch aimed at testing and validating technologies that will be applied to the company’s first orbital-class launch vehicle, Vikram 1, which the company plans to launch in 2023.
