The Ursa Minor Interstellar City (UMIC) project was born out of the need to create accessible and sustainable space simulation environments on Earth. Inspired by NASA’s Neutral Buoyancy Laboratory (NBL) and NEEMO underwater project, as well as ESA’s CAVES programme, UMIC reimagines these concepts to provide affordable, eco-friendly simulations that bring space exploration closer to ordinary people, considering the following scientific principles:

• Low-gravity simulation: Using underwater neutral buoyancy environments to replicate microgravity for astronaut training.
• Closed ecological systems: Conducting oxygen regeneration and resource recovery experiments to simulate living conditions on the Moon and Mars.
• Human adaptation studies: Exploring human survival in extreme environments, akin to ESA’s cave studies, through underwater confined space experiments.

A Journey of Innovation
​In 2020, collaboration with Professor Thais Russomano on the Evetts-Russomano (ER) CPR method sparked the idea for UMIC’s Underwater Space City. Over four years, UMIC has developed the complete underwater space city elements: EVA training spacecraft, animal spacecraft, lunar commuter motorcycle, space farm, the world's largest astronaut helmet, and the smallest underwater cafe - Galaxy Cat Cafe (see videos below). We can even provide astronauts with a cup of hot coffee underwater, and broadcast space education for young people around the world, truly realizing the popularization of space exploration education.

​Mission and Impact
UMIC’s goal is to train commercial astronauts to thrive in space and on alien surfaces while establishing ecological, multi-species habitats. By fostering collaboration and resilience, it not only advances humanity’s path to becoming a multi-planetary species but also strengthens our ability to protect Earth and preserve its ecosystems

The webinar, organised by InnovaSpace Director Prof Thais Russomano, was presented by 4 students from the Remote Medicine iBSc program, National Heart & Lung Institute, Imperial College London, and in association with the MVA (Moon Village Association). The focus of the event was on one of the most critical aspects of future lunar habitation: human health.
Join the student panel as they explore the unique environment of the Moon, the history of its human exploration from NASA Apollo Mission first steps to future Artemis plans, its potential impact on human physical health and mental well-being, Moon research and Earth-based space analogues, and research limitations and gaps in the knowledge.

Congratulations to the presenters - Manvi Bhatt, Nareh Ghazarians, Diya Raj Yajaman, & Elvyn Vijayanathan - and good luck with your future careers. 

​I became involved in Space research whilst my husband was completing his PhD in the early 90s, acting as ‘flight nurse’ for several parabolic flight human research studies. I went on to co-develop the Evetts/Russomano (ER) technique for basic life support in space, while continuing to work as a renal specialist nurse in the UK.

​In 2011, I became the sole flight nurse for the European Astronaut Centre in Cologne, Germany. I enjoyed two successful years working closely with the flight surgeons within the Operational Space Medicine Unit (OSMU), as it was called then. I was part of a team responsible for the day-to-day management and administration necessary for maintaining ESA (European Space Agency) Astronaut health. One of my key responsibilities was to track and retrieve data from medical events related to ‘pre’, ‘in’ and ‘post’ space flight activities.  
 
The role also involved working as the interface between OSMU, NASA, the ESA flight clinic and occasionally the Russian Space Agency, coordinating somewhat complex planning to ensure all flight medical examinations were completed within a rigid timescale from an Astronaut’s initial mission assignment, 18 months before they flew, to two years post-mission. The examinations took place at the locations of all 3 agencies to accommodate an Astronauts packed international training schedule. Astronauts who weren’t assigned to a mission, also required coordination of annual medicals locally.

​I particularly enjoyed good relationships with the NASA flight nurses who I had the pleasure to meet when visiting the Johnson Space Center in Houston. It was a great opportunity to meet all those I had been communicating with by phone and email, to cement our good working relationships.
 
I represented OSMU at weekly events such as the astronaut training coordination meetings, where planning and updates on training schedules and upcoming flight assignments would be discussed. Each team involved in preparing an Astronaut for flight was granted a certain number of hours of the astronaut’s time from a packed pre-mission schedule, to complete the necessary training and preparatory requirements. Arduous negotiations were required with other departments and the agency central mission organisation authority, should a team think they needed extra time to complete their activities.
 
As the Flight Nurse I was responsible to lead weekly clinical meetings to update the flight surgeons on any new information and issues relating to an astronaut’s health and the work underpinning their welfare.

A review of original article - Building Robots For “Zero Mass” Space Exploration - written by Jacek Krywko (8th Feb 2024), published on the ARS Technica website

​The idea of exploring space without lugging around tons of gear sounds like something straight out of a sci-fi flick, but guess what? It might just be closer than we think! This article dives into the wild world of "Zero Mass" space exploration, where scientists are ditching the heavy payloads and instead relying on super-intelligent robots and nifty building materials.
 
Think about it: sending stuff into space costs a fortune. Like a serious fortune. But what if we could cut down on all that weight and send up a bunch of self-replicating robots armed with super cool building blocks? That's the dream these NASA and Stanford folks are chasing.

​They're talking about using materials that can rebuild themselves, which is mind-blowing. It's like something out of a sci-fi novel from way back in the day. And get this - they're not just dreaming about it. They've built a bunch of these little building blocks called "voxels" and tested them out. These things are crazy vital but weigh next to nothing. So you can pack a bunch of them in your backpack and build whatever you need on the fly - like a shelter, a bridge, or even a boat!
 
And here's the kicker - they're not just building stuff on their own. They've got these robots doing all the heavy lifting. These robots are like little construction workers, piecing together structures autonomously. It's like watching a futuristic version of a construction site!

​But it's not all just for show. They're thinking about using this tech to build towers on the Moon! Yeah, you heard that right. Towers on the freaking Moon! It's all about maximizing sunlight and getting the best communication signals. And with this tech, they reckon they can pull it off.
 
So, while we might not be hopping on spaceships and jetting off to distant planets just yet, it seems like we're getting closer every day. Who knows, maybe one day we'll all be living in moon towers built by robots. Hey, a guy can dream, right?

​Microgravity is a fascinating topic when it comes to the study of astronaut health. When humans are exposed to microgravity, the effects on their bodies can be quite significant.
One of the first things to understand about microgravity is its effect on the musculoskeletal system. In the absence of gravity, astronauts experience a decrease in muscle mass and bone density. The lack of load-bearing activity in microgravity leads to muscle atrophy and bone loss. This can result in decreased strength and increased risk of fractures once astronauts return to Earth.
Another area of concern in microgravity is cardiovascular health. On Earth, gravity helps to pump blood towards the lower extremities. In microgravity, this effect is greatly reduced, causing fluids and blood to shift towards the upper body. This can lead to a decrease in plasma volume. Astronauts often have to undergo intense exercise regimes during their space missions to counteract these effects.

The immune system is also affected by microgravity. Studies have shown that the immune response of astronauts is suppressed during spaceflight. This can make them more vulnerable to infections and diseases. Researchers are still studying the exact mechanisms behind this phenomenon and are trying to find ways to boost the immune system during space missions.
Microgravity also has an impact on the astronaut's vision. Some astronauts have reported changes in their vision, such as an increase in visual blurring and other visual disturbances. This condition, known as spaceflight-associated neuro-ocular syndrome (SANS), is still being studied to understand its underlying causes and potential long-term effects.
In addition to physical health, microgravity can also impact an astronaut's mental well-being. The unique environment of space, with its isolation, confinement, and lack of natural daylight, can lead to psychological challenges such as mood swings, sleep disturbances, and increased stress. NASA and other space agencies provide mental health support and psychological training to help astronauts cope with these challenges.

​To mitigate the negative effects of microgravity on astronaut health, space agencies invest in various countermeasures. These include exercise programs, special diets, and even medications. Additionally, researchers are constantly studying new technologies and strategies to protect and enhance astronaut health during long-duration space missions.
In conclusion, microgravity has significant effects on astronaut health, impacting various systems in the body. The study of these effects is crucial to ensure the well-being and safety of astronauts during space missions. By understanding and addressing these challenges, we can continue to push the boundaries of space exploration while also safeguarding the health of those who venture into the final frontier.

This post does not attempt to address the many changes the human body experiences in space, such as volume modifications in body compartments, fluid shifts, structural configuration in receptor* morphology and, as a consequence, possible variations in pharmacology response, etc.

Rather, this post presents some of the technical challenges that an anaesthesiologist may encounter in space.
​
Confined space.
On Earth gravity keeps everyone’s feet on the ground. Different pieces of equipment can be repositioned depending on the procedure, machinery can be brought in as needed (XRay scans in orthopaedics, for instance), electric cables can be switched to other convenient wall sockets etc. In a fixed volume space capsule, you don’t have all these possibilities. Everything is measured for maximum volume efficiency. Taking into consideration that anything can and will float if not properly anchored, we can imagine what an “anaesthesia dance” could happen!

What equipment?
On Earth an anaesthesia workstation is always present in the OR. Depending on its complexity its volume can vary between a medium size fridge to a large double-doored one, just put on its side. You don’t have this amount of deposit in a space cabin, but let’s suppose for one moment that you do - you then need an Anaesthesia Gas Scavenging System (AGSS), which removes the anaesthesia gases that have leaked out or at the end of the procedure. On Earth, these gases are expelled into the atmosphere (there is a lot to talk about this and the greenhouse effects too) and the air currents around any medical facility carry them away. In space you don’t have this. Any gas must be expelled using energy, an active process. Otherwise, the whole cabin will become a big anaesthesia machine with all crew members affected. And, speaking of energy, an anaesthesia workstation is also powered by electricity, which is a limited resource in space, depending on the surface of the solar (or light in general) panels. This energy must be stored and used for other life maintenance systems as well, of which a critical example is the Sabatier reactor that provides oxygen. 

Regional anaesthesia
The simplicity and portability of the necessary equipment makes this type of anesthesia attractive. For peripheral neural blocks all you need is a simple ultrasound machine and dedicated needles. The potential drawbacks are that the technique/s need to be taught on Earth but their “transposition” to space is a bit problematic. If the spinal/epidural anaesthesia is relatively simple to learn, the USG (ultrasound guided) blocks are more challenging. Furthermore, the bodily fluid shift due to the lack of gravity causes many tissues to change their tridimensional appearance, leading to increased difficulty in performing the block.

The cardiovascular responses that accompany spinal/epidural anaesthesia on Earth, in terms of heart rate and blood pressure, are different in space. There may be a lack of reactivity so a certain reduction in blood pressure, for example, might not be compensated.
We need to remember that the hostile environment in space, especially radiation, affects not only the human body, but also many sensitive electronic components of medical equipment, leading to possible dysfunction. Monitors can potentially de-calibrate and all the information you receive may become inaccurate.

Fluids
Preparing and administering a fluid on Earth is routine, however, the lack of gravitation in space poses other challenges: air and fluids do not mix. It is called “lack of buoyancy”. Unless we use special equipment to separate fluids from air nothing can be delivered to the patient. This statement is true also for the anaesthesia vaporiser (a special closed recipient that contains the anaesthesia substance); not only can you not simply fill it the way it would be done on Earth, but even if you could, the anaesthesia liquid that becomes vapour cannot separate from the fluid from which it originates. It just cannot exit the vaporiser. Below is a small example of how liquids behave in space and what happens when a liquid exits a recipient:

​The same is true for another type of anaesthesia, called TIVA = Total Intra Venous Anaesthesia. This technique uses a dedicated syringe pump that pushes different anaesthesia substances through an intra venous line. It’s a useful technique both in terms of volume and energy expenditure, but again we face the same problems: how to fill the syringe without air bubbles and how to protect the electronics of the syringe pump (in fact a computer in all respects) from the deleterious influences of space radiation!

As you can see, space medicine is a very important topic and many people dream of its future use. Yet, we still have a long way to go! With the advent of intermediary space “stops” and the continuous development of new technologies, every challenge will be solved, sooner or later.

Time to catch-up with our colleague from the east, Chris Yuan, who very enthusiastically and capably established the Ursa Minor project in China, under the umbrella of the Planetary Expedition Commander Academy (PECA). It involves the development of new technologies and innovative training courses to encourage and inspire a future generation of space science researchers and astronauts.

​As previously reported in 2022, Chris and his students learned how to perform the Evetts-Russomano CPR technique underwater on a manikin while diving, as the water simulates the weightlessness that is present in microgravity. This practice now forms part of a larger course, the Ursa Minor Interstellar Expedition Program, giving the opportunity for 12- to 18-year-olds to participate in an underwater space science training camp.

The first edition of the InnovaSpace Journal Club was dedicated to a prospective cohort study on jugular venous flow in astronauts aboard the ISS. From this study, the issue of jugular vein thrombus formation arose, which led to some fascinating discussion on how we could possibly manage and mitigate this novel risk to astronaut health. 
Therefore, I thought it appropriate to use the second edition of the InnovaSpace journal club to cover the issue of bleeding in space.

PAPER PRESENTED & DISCUSSED:

We used a 2019 literature review which evaluated different haemostatic techniques in remote environments and proposed a major haemorrhage protocol for a Mars mission.
The article itself stressed that while the estimated risk for major haemorrhage on a Mars mission was not very high, there were still many possible causes for a big bleed such as trauma and high dose radiation. Additionally, the changes to circulatory physiology observed in microgravity may mean astronauts are less able to cope with even small amounts of blood loss.
While the literature search itself left a lot to be desired as only 3 of the 27 papers were randomised controlled trials (RCTs), the results were interesting.
