BENGALURU: With the pandemic having enveloped 2020, Isro is targetting at least seven more launches, including the uncrewed Gaganyaan mission, from India this year, while PSU New Space India Limited (NSIL) plans to launch one satellite through a foreign launch provider.
Of the six other than Gaganyaan to be launched from the spaceport in Sriharikota, three will be earth observation, including one for ocean studies, one remote sensing satellite, a commercial launch, and one navigation satellite (see graphic).
A science satellite to study the Sun (Aditya-L1) that was initially targeted for this year won’t happen. And, among the launch vehicles, other than the PSLV, Isro will launch three GSLV missions, including the mark-III as part of the uncrewed Gagnayaan mission. Two more will be SSLV (small satellite launch vehicles) class of rockets.

Aside from this, as reported by TOI earlier, NSIL is planning to launch the GSAT-24, being acquired and launched for a private customer — Tata Sky’s DTH business — through Arianespace.
Isro chairman K Sivan said: “If you look at the number, then we consider it to be 14 more missions as each launch is two missions (one launch vehicle and one satellite). We are confident of achieving this target and top priority is for Gaganyaan.”
He said Aditya had to be pushed to next year as the next launch window — missions to Moon, Sun and other planets have specific windows during which launches can take place — is only available then.

Stating that the human rating of GSLV is progressing as planned, Sivan said 2021 will see multiple indigenous technologies tested.
“We will have two SSLV launch vehicles technology demonstration flights, we will be testing the revamped GSLV in terms of rockets. On the satellite technology front, we are looking to test the election propulsion on satellites, use two atomic clocks developed indigenously on the NVS-01 and also a key component called TWTA (Traveling Wave Tube Amplifiers) in a communication satellite,” Sivan said.
Isro is hoping to completely stop importing these technologies, in line with the Centre’s Atmanirbhar mission, and this year will prove key in deciding how quickly the space agency can shift to indigenous technology. “Apart from giving us the edge technologically, it will also save us a lot of foreign exchange,” Sivan said.

Earth observation, lunar cooperation and satellite navigation figure in discussion

Indian and Japanese space agencies on Thursday reviewed cooperation in earth observation, lunar cooperation and satellite navigation, and also agreed to explore opportunities for cooperation in “space situational awareness and professional exchange programme”.

This was agreed during a bilateral meeting between the Indian Space Research Organisation (ISRO) and the Japan Aerospace Exploration Agency (JAXA) held virtually.

“Both agencies signed an Implementing Arrangement for collaborative activities on rice crop area and air quality monitoring using satellite data,” an ISRO statement said.

India and Japan are already working on a joint lunar polar exploration (LUPEX) mission and the two space agencies have been working on the mission that aims to send a lander and rover to the Moon’s south pole around 2024.

Early this month, India and Italy decided to explore opportunities in earth observation, space science and robotic and human exploration.

Last month, India and Australia signed an amendment to the MoU which will build on the Comprehensive Strategic Partnership. Both countries are also in discussions for Australia to host vital tracking infrastructure to support the Gaganyaan manned space flight mission.

Chandrayaan-3 launch delayed further to 2022

Chandrayaan-3 is critical for ISRO.

Chandrayaan-3, India’s third mission to Moon, is likely to be launched in 2022, ISRO chief K. Sivan has said.

The COVID-19 lockdown has hit several projects of the Indian Space Research Organisation (ISRO) including Chandrayaan-3, which was scheduled to be launched in late 2020, and Gaganyaan, the country’s first manned space mission.

Unlike its predecessor, Chandrayaan-3 will not have an orbiter.

“We are working on it. It is the same configuration like Chandrayaan-2 but it will not have an orbiter. The orbiter launched during Chandrayaan-2 will be used for Chandrayaan-3. With that we are working on a system and mostly the launch will be next year in 2022,” Mr. Sivan told PTI.

Chandrayaan-2, aimed at landing a rover on unchartered Lunar South Pole, was launched on July 22, 2019 on board the country’s most powerful geosynchronous launch vehicle.

However, the lander Vikram hard-landed on September 7, 2019, crashing India’s dream to become the first nation to successfully land on the lunar surface in its maiden attempt.

Chandrayaan-3 is critical for ISRO as it will demonstrate India’s capabilities to make landing for further interplanetary missions.

He said ISRO is targeting December to launch the first unmanned mission under the Gaganyaan project. The mission was originally scheduled to launch in December last year.

It will be followed by another unmanned mission and the third leg is the main module, he said.

Gaganyaan envisages to send three Indians to space by 2022. The four test pilots selected for the mission are currently undergoing training in Russia.

When asked about the launch of the third module of Gaganyaan – the manned mission – Mr. Sivan said, “A lot of technology needs to be demonstrated. We will decide on the time (of the manned mission) after checking whether all the technology is perfect.”
