​Humans are planning to one day build settlements beyond Earth, although it should be noted that, currently, the total number of humans who have ventured beyond Earth (astronauts) is minuscule in comparison to the 8 billion global population. There is still a lot of work to be done. We are still not sure if space travel will be possible for everyone in our respective lifetimes, but in the meantime, there are several cosmic events that we can all witness from this blue dot on which we live. These include eclipses, meteor showers, etc. that occur at specific times, and give us a sense of belonging to the cosmos! So, we should try not to miss these cosmic events if at all possible. There are astronomy clubs and science museums that can be visited, or sometimes we can even view these events online using applications like Stellarium or Youtube, etc. 

A few members of the InnovaSpace Space Crew working group have actively engaged in observing two vital cosmic events that took place toward the end of 2022 - the Partial Solar Eclipse (25.10.2022) and Total Lunar Eclipse (08.11.2022). ​ Below are a few snapshots of the recent eclipses. 

Recently, more and more space dreamers and serious scientists foresee a human travelling to Mars.
The closest planet to us in a centre to periphery direction from the Sun, Mars is still at 86,362 million km distance. Hmmmm…
​
It is said that in similar conditions and with similar materials, the resultant product will usually look the same. Well, Mars is somehow considered a terrestrial planet.
For illustration, I bring two pictures to your attention - similar, but with evident differences. Both show sunrise, but one is from Mitzpe Ramon in Southern Israel, while the other is from Mars. Obviously, the second image was not taken by me!

With a bit of imagination, we can compare both images - would you take your family at the weekend for a grill (BBQ)? In both places?
A grill? Well… let’s see what we need. Here on Earth, we know. But what do we have on Mars?

Minimum temperature of -110 degrees Centigrade - too cold to eat outside.
Maximum temperature is +35 degrees Centigrade. That’s ok, a bit like Mitzpe Ramon. So, let’s do the grill. But something’s missing!
Yes, for fire we need some oxygen. The oxygen level on Mars is 0.2%, roughly 1/100 of what we have on Earth. Hmm… definitely not enough.

​And for a good and tasty grill you need to stay next to it and watch the meat, flip it from time to time. This is difficult too as the gravity on Mars is 3.721 m/s2, roughly 1/3 of that on Earth. Kinda floating a bit, isn’t it… ?
​
So, until we are able to have a grill on Mars, provided we can transport enough meat there and keep it edible, let’s enjoy a traditional and classic one in our own backyard. Enjoy!

But…look to the skies from time to time…You will see Mars with the naked eye.
​
BTW, we’ve started producing artificial meat over here…

In this quote, Sarabhai emphasises achieving harmony in the state of disorder to attain greatness.
               Perhaps you may have heard about the Indian Space Research Organisation (ISRO), the most cost-effective and efficient space organisation in the whole world, the one that succeeded first-time in its Mars mission and also with a multitude of other ambitious missions. But... do you know the people who were involved in its making?

Let me introduce you to ​Dr. Vikram Sarabhai - the man involved in the organisation's very foundation and considered to be the Father of ISRO. This remarkable personality also contributed to India and the world in terms of institutional building and serving society through science and technology. He also excelled in helping India to achieve global standing in nuclear power and was Founder of the first Indian Institute of Management (IIM).
A multitalented guy, right?
So, let's get to know more about our hero, Dr. Vikram Sarabhai…..

Early Life & Education
Vikram Ambalal Sarabhai was born to Ambalal Sarabhai and Sarala Devi on the 12th August 1919 in Ahmedabad, Gujarat, India. His father was a textile industrialist and his mother a teacher, who ran the school in which Sarabhai underwent his primary education. Sarabhai had a keen interest in maths and science, and after passing a higher education intermediate science exam at Gujarat College, Ahmedabad, he then studied 'Natural sciences' at St John's College, University of Cambridge in England, graduating in 1940.          
Unfortunately, the sudden outbreak of the Second World War forced his return to India, where he joined the Indian Institute of Science (IISC), in Bengaluru (formerly Bangalore). He conducted research on cosmic rays under the guidance of another pioneering Indian scientist and Institution builder Dr. Homi J Bhabha and supervision of Indian Nobel Laureate, Sir Chandrasekhara V. Raman. Within 2 years of his research, he submitted his first scientific paper on the "Time distribution of cosmic rays" in 1942. He finally returned to Cambridge University in 1945 and obtained a PhD in 1947, with his thesis entitled “Cosmic Ray Investigations in Tropical Latitudes”. 

​Would a tree taken to grow on a planet smaller than ours and with less gravitational force, such as Mars where gravity is one-third that of Earth (hypogravity), have branches and leaves that point upwards, away from the soil?

​On the other hand, what if we took a tree to Jupiter, the biggest planet in the Solar System, where the force of gravity is 3.5 times that of Earth (hypergravity)? On this gigantic planet would tree leaves and branches be pulled downwards, unable to defeat gravity, perhaps looking more like the image below?

​Or let’s consider a different scenario in which a tree is already native to a planet that has gravity bigger than on Earth – growing from a seed it would adapt straight away to the gravitational force of the planet, and perhaps grow differently. Do you think it might grow with a trunk that is thicker, larger, stronger, like the tree below?

​For the moment, however, until we can transport trees and plants to grow on other celestial bodies or perhaps even discover a planet where vegetation grows naturally, we will have to admire the trees that grow and are shaped by the gravitational force of our own planet Earth. These are the trees we have been lucky enough to grow up with, the usual ones that we are so accustomed to, the trees that we must take good care of and protect well, as they are things of beauty and so rare in our Solar System and beyond.

My name is Lucas, I am a doctor in the UK working in anaesthetics (or Anaesthesiology for any American readers) and intensive care medicine. I have had an interest in space medicine for over 10 years now, inspired by none other than Prof Thais Russomano who has mentored me over the years and still does. My Master’s dissertation (back in 2009) focused on CPR (cardiopulmonary resuscitation) methods in microgravity, with my continued research interest surrounding critical care in space. I am careful to say that I am a doctor with an interest in space medicine and physiology, as opposed to a ‘Space Doctor’ – as there are many individuals out there who have committed many more years than I have to this field and are vastly more experienced than I am! A club I aspire to join one day.

The idea of this blog, or series of blogs, is to look at some of the latest research in space physiology and space medicine, then consider how this will play out clinically. With a particular focus on critical care and potentially worst-case scenarios when in space (or microgravity environment). Something all doctors will have done in their careers; we are equipped with the skills to critically appraise papers and then ask if they are clinically relevant, or how will it change current practice.

​Over the last 60 (ish) years of human space flight, there is lots of evidence to show that there are many risks when the human body has prolonged exposure to microgravity, which can affect most body systems – eyes, brain, neuro-vestibular, psychological, heart, muscle, bone, kidneys, immune system, vasculature, clotting and even some that we haven’t fully figured out yet. But then what needs to be done is to tease out how clinically relevant are these from the research, how could that potentially play out if you were the doctor in space, then how to mitigate that risk and potentially treat it.

Space provides boundless opportunities for human existence and innumerable threats to human health.
​The question is, are we yet prepared to deal with a catastrophic event, such as a cardiac arrest in space?

ABSTRACT:
Introduction: Metaverse is the augmented virtual world formed by convergence of virtual and physical space. Users interact within this created world, meeting each other virtually, immersing themselves in performing virtual activities, which subsequently could lead to real experiences. Conventionally, the healthcare “industry” is conservative in deploying future ready technology.
Aims and Objectives: This overview discusses the untapped potential of metaverse applications in healthcare from a clinician’s perspective. Bereft of technical jargon, the article points out the advantages, disadvantages, limitations, and challenges in actual deployment of the metaverse in clinical practice in the real world. The exponential transformation occurring in this area is highlighted. The highly technical literature is simplified for easier comprehension.
Findings: Clinical applications, use of the metaverse in training, education, and augmenting telehealth consultations, in an immersive milieu, is discussed. Direct “in-person” interaction with digital products and solutions will be a new experience for a healthcare provider and the beneficiary. The role of digital twins is illustrated. Consultation process and various clinical applications in the metaverse are outlined. Technology‑enabled futuristic training and education is discussed.
Conclusion: Demonstrating significant improvement in healthcare outcomes using the metaverse will be difficult to prove. This alone will ultimately lead to the development of a business model, insurance reimbursement and behavioral modification necessary for accepting and using, a hitherto unused method in patient care.
Keywords: Augmented reality and healthcare, blockchain and healthcare, metaverse and healthcare, virtual reality and healthcare
