So Close Yet…Not Done!

Chandrayaan-2
Vikram (lander) with Pragyan (rover)

I never thought I’d write this post on a sombre note because along with the rest of a billion folks I was cheering for the Chandrayaan-2 and the Vikram landing. But space exploration is nothing if not a game for cantankerous nerves and success is never taken for granted. The ‘Vikram’ lander was primed for a precise touch down on the southern pole of the Lunar surface which was to be done autonomously.

Now comes the crucial part. The lander was descending at a high speed and was programmed to brake to descend slowly, hover and then land softly on the rocky, cold and dark lunar surface. From the mission control, after the ‘Rough Braking’ phase ended at 2.1 km the green dot on the red trajectory line wobbled and suddenly dropped vertically, I knew right then that something had gone wrong. It brought a lump to my throat when I watched the ISRO chairman approach the PM of India in the viewing gallery and my worst fears had come true. Losing communication with the lander obviously meant it had crashed but there was still a glimmer of hope because the orbiter was still communicating with the lander. Only 3 nations before this have had the privilege to land spacecraft on the Moon and India came very close in achieving that rare feat today! Her day would come pretty soon.

My fingers crossed bu the lander Vikram has been lost in all probability although the orbiter would continue sending pictures of the Lunar surface for the next year. That to me is a resounding success for the Chandrayaan-2 mission. There were several aspects linked to the success of the indigenously-designed ‘Pragyan’ rover as well including confirming data of the presence of water for setting up a future moon-base. Now all eyes would be transfixed on ISRO finding success in their next mission (especially, Gaganyaan), that’d cool the sting of this Lunar setback and put it on the backburner forever. More power to the scientists at ISRO!

Climate Catastrophe, Up Ahead

Climate Catastrophe

In a news report that I read today, scientists at the Intergovernmental Panel on Climate Change (IPCC) have cautioned that we might be heading for a ‘climate catastrophe’. Titled ‘Global Warming at 1.5ºC’, the analysis which is authored by around 90 scientists at the IPCC, has suggested keeping global temperatures well under 1.5ºC, although we might be going completely off track & heading towards an increase of 3ºC instead! For a perspective, the Paris Agreement had a long-term goal of keeping the increase in global average temperatures to well below 2°C above pre-industrial levels; and to limit the increase to 1.5°C, since this would substantially reduce the risks and effects of climate change. Back home in Canada, several provinces are now preparing to rally against the Trudeau government’s initiative to introduce a carbon tax plan, just as, to my surprise, the Ontario government under Premier Ford scrapped the provincial ‘cap-and-trade’ carbon tax plan, towards, what they described as, “fulfilling the government’s commitment to reducing gas prices by 10 cents per litre.”

The target of 2ºC which was previously thought as reasonably manageable the IPCC now suggests that even going past 1.5ºC is not an option anymore and it would significantly alter the planet’s livability. Hans-Otto Portner, a German scientist who co-chaired one of the panel’s working groups, says:

[perfectpullquote align=”right” bordertop=”false” cite=”” link=”” color=”” class=”” size=””]“Every extra bit of warming matters, especially since warming of 1.5 C or higher increases the risk associated with long-lasting or irreversible changes, such as the loss of some ecosystems”.[/perfectpullquote]

Simply put, policymakers across the board need to strategize in integrating more sustainable ways to reduce carbon emissions by transforming the biggest calamity facing mankind today into their biggest opportunity to save the species tomorrow. It’s a wake-up call, to say the least.

How We Can Prevent The Climate Catastrophe

As consumers of this vast but fragile ecosystem, we have a grave responsibility to preserve the environment by preventing the temperature of our Earth from going beyond 1.5ºC. The IPCC report states that the ‘climate catastrophe’ could be avoided provided we make some rapid but significant changes to four big global systems – energy, land-use, cities and industry. And without the participation of individuals & entrepreneurs, that target may not be achievable. Here’s a checklist of what we all can collectively do to reduce the carbon footprint:

  • Buy less meat, milk, cheese and butter and more locally sourced seasonal food – and throw less of it away
  • Drive electric cars but walk or cycle short distances
  • Take trains and buses instead of planes
  • Use video conferencing instead of business travel
  • Use a washing line instead of a tumble dryer
  • Insulate homes
  • Demand low carbon in every consumer product

It’s not easy at all, but a sustained interest, widespread promotion & a shared commitment over a period of time could make our planet become greener and cleaner again.

For The Love Of Our Planet Earth

The winter this season showed no signs of abating and it was anything but ordinary. Then last week, just as I was expecting the spring to bring some warmth and sunshine to the chill, there was an unprecedented ice storm sweeping across the city of Toronto. It also resulted in some serious collisions on the roads & power outages in parts of the city. Some would have attributed this abnormality to the ‘wrath of nature’ or ‘God’s will’, but I believe it was a direct result of the effects of climate change more than metaphysical. Sadly, we only pay attention to ‘climate change’ from the media when a rising mercury scorches the earth or causes drought, though it also affects the monsoon patterns. In some areas, it brings incessant deluge that floods low-lying areas while displacing human settlements. Now, it’s anybody’s guess whether the forecast for this year would be chilly, soggy, or oppressively simmering! Nonetheless, on this Earth Day, we must pledge to ‘act green’ in protecting our planet, it’s the only place in the entire universe that we must love & preserve. Let’s go green!

Stuff I Didn’t Know About This Image of India

I am passionate about anything that is even remotely related to space, and this one has stuck with me since schooldays. So, as a kid from India in the 80s’, I would ponder endlessly over this satellite imagery on the back of my geography textbook probably the 6th or 7th grade, that showed the Indian peninsula alongside the island nation of Sri Lanka. All along I was curious to know the origins of this photo, like, who captured it? What was that strange pole? etc., and I was thrilled to have stumbled upon a NASA website carrying this information.

India - Gemini 11 Photo

Picture of peninsular south India was taken from space in the 60s!

So this image was taken by the Gemini 11 crew (Conrad-Gordon) on September 14, 1966 “using a 70 mm lens on a modified Hasselblad film camera”, and I don’t know why but it somehow made it to the geography school textbooks in India and into my inquisitive mind. And as I discovered later, that “strange pole” in the picture is the “7-FT Retractable L-Band Boom Antenna” from the Agena Target Vehicle.
