ISRO Land, Challakere

Challakere is a town in Karnataka which is roughly 3.5 hour drive North East of Bengaluru. This is a place where a ₹2,700 crore plan to build India’s Human Space Flight Center (HSFC). This was where some of the tests for Chandrayaan 3 are being done.

Tender Notice to clear Bellary Jali

As usual, this news comes not from ISRO but from a tender notice posted on ISRO’s website. Based on this, I looked at the area on Google Maps. I found a few things that I shared on r/ISRO. As is usual, this is not a new discovery.

This is land allocated to ISRO in Science City. Hence, you can see the campuses for Indian Institute of Science (IISc), Defence Research and Development Organisation (DRDO) and even Bhaba Atomic Research Station (BARC).

You can also see the plans that were shared for the construction of this land here. Essentially, the land where we did these tests will be built over by the HSFC.

Chandrayaan-3 tests

These craters are for what are called the Lander Sensor Performance Test (LSPT). LSPT-1 and LSPT-2 were conducted for Chandrayaan-2. The tender is for clearing the green swathes that you see. It is apparently full of a shrub called Bellary Jali which needs to be cleaned up before tests for Chandrayaan-3 can be conducted.

Details of LSPT-1 and LSPT-2 were shared in Upagrah Apr-Jun 2017 issue (archived in Google Docs by u/Ohsin). This is the in-house magazine for U R Rao Satellite Center (URSC).

The test involves flying a Beechcraft Super King Air B-200 belonging to the National Remote Sensing Center (NRSC) over the craters made for the purpose. The plane flew from 500 m to 7 km in altitude to simulate various landing conditions. They also flew early in the morning to get the same lighting conditions as on the landing site on the Moon.

RLV Landing Experiment near Chitradurga

There was mention of a Reusable Launch Vehicle (RLV) Landing Experiment at Chitradurga.

Snippet mentioning the RLV Landing Experiment in the ISRO Annual Report 2020-21.

Interesting term in the picture above is the pseudolite (pseudo-satellite).

While exploring the surrounding of Challakere, I spotted this, which could be a possible runway to which the RLV will glide and land on.

This blog post is a small effort to read documents and share with you the possible rabbit holes. Following them is up to you.

Solo (2017)

The music from this movie introduced me to Agam, Thaikkudam Bridge and Masala Coffee. It was this music that made me curious about the movie. I had seen bits of it before but when I saw the movie was on Netflix, I thought that it was good use if any of my month long subscription.

I saw the Tamil version of Solo. It stars Dulquer Salman. It constitutes four parts – the elements of Earth, Air, Fire and Water. It looks at the four forms of Shiva. I loved the art and the filming style.

There are many gaps in the story that I was curious about. I like open ended stories. I like non-reveals. I loved this movie.

The Minimalists: Less is Now (2021, Netflix)

The Minimalists are a duo who blogged about minimalism alongside others in the late noughties (2000’s). In 2015, they made a move called Minimalism, about the movement. The movie was a conversation that the Minimalists had with many prominent participants and bloggers of the movement.

Many of the bloggers who participated in that movement have now changed their focus away from Minimalism and moved on to other things. I, myself feel drawn more to the idea that Greg McKeown presented in Essentialism. Minimalism is a movement that forms an ideal foundation for many more pragmatic movements and ideas.

The Minimalists are back in 2021 with a follow-up documentary called Less is Now. In this documentary, they talk about their own story. It features a few experts who talk about the financial, economic and environmental burden cost by “stuff”. The story is interlaced with stories of many ordinary individuals who followed the principles laid down by the movement.

The film is directed by Matt D’Avella, whose YouTube channel I follow. I love to watch the videos that Matt directs and that’s possibly the only reason I wanted to watch this documentary.

I subscribed to a month of Netflix again just to watch this 50 minute documentary. I think just watching Matt’s film making was worth watching this.

Following The PSLV C-50 mission on Twitter

After a long time, I live-tweeted the launch of the PSLV-C50 mission.

From my newsletter, edition #8

CMS-01 was earlier called GSAT-12R. The change of names is for ISRO’s new naming convention. It has named it’s remote sensing satellites as EOS for Earth Observation Satellite and it’s geostationary satellites as CMS for Communications and Meteorology Satellites. ISRO has provided no rationale for the renaming of satellites.

PSLV-C50 mission consisted of a PSLV flown in it’s XL configuration. XL stands for Extended Length. It’s 6 strap-on boosters are extended in length. It carries 4 ground-lit boosters and 2 air-lit boosters. CMS-01 was the only payload on board. The PSLV placed the satellite in the intended orbit in 1200 seconds. The intended orbit was orbit is 284 km X 20650 km at 17.86 deg inclination.

This is ISRO’s second launch from Indian soil in 2020 and third launch including one from Kourou on board the Ariane V launch vehicle.

In the post-launch press conference, ISRO’s Chairman, K Sivan announced that PSLV-C51, ISRO’s next launch would carry Anand satellite of Pixxel Space. This would be India’s first private satellite launch. Pixxel Space is a remote sensing satellite builder and data provider.

Space going back to Kerala?

While listening to Mission ISRO, I realized how the focus of space activities changed from Thumba to Bengaluru in the 1970s when Prof. Satish Dhawan became ISRO Chairman after the death of Vikram Sarabhai, the father of the Indian space program.

In today’s episode, it was discussed how people in Kerala opposed the move to build Aryabhata, India’s first satellite to Bengaluru. Surendra Pal in his reconstruction says that people blockaded the movement of equipment from Thumba. It seems scientists carried some tools and books as personal luggage from Thumba to Bengaluru.

In Thiruvananthapuram, a space park was started in 2019. Many space companies have moved there. When listening to this episode today, I wondered if this is a return back to the 1960s.

While I do not want to indulge in counterfactual of what would have happened if the space program had stayed in Kerala, I think the creation of the space park is another opportunity to unlock that potential.

Kerala has lost several investment opportunities. It has lost so because of perceived unionism and the political troubles many industries have faced. But, given the slow loss of a remittance economy, there is a slow return of small and medium enterprises in the state. Unfortunately, the state has slowly lost land with no space for large industries.

The Space Park idea is a great place for space companies to register and operate from. Will it be inviting enough to get companies to move from Bengaluru to Kerala Space Park?
