Welcome to a new and exciting Marslog! Diaries from Analog Mars will be presented as a sequence of personal entries from Mars Society of Canada Director Jin Sia, who has deployed to the Utah desert to conduct analog space exploration… Read More »Diaries from Analog Mars: Preparing for Launch
Jin Sing Sia
Jin has been an aspiring space explorer for as long as he can remember. He was inspired by The Case for Mars to dedicate his life to landing explorers on the red planet, and is currently studying mechanical engineering at the University of Waterloo in Ontario, Canada. A Malaysian citizen by birth, he traveled on his own to Canada at the age of 15 to get closer to the cutting edge of the space industry. Jin is also an avid environmentalist, human rights activist, and die-hard science fiction lover. He is currently preparing for a simulation Mars mission at the Mars Desert Research Station as part of Crew 228 (mdrs228.com). With the Mars Society of Canada, he is applying his enthusiasm for space exploration and growing command of engineering principles to research and development projects, writing for the website, and more. As part of a core group of volunteers, he supports MSC activities and operations.

In our previous article, we covered the basics of rocket engines, but we only scratched the surface when it came to fuel-oxidizer combinations. While hydrogen-oxygen and kerosene-oxygen dominate the world of launch vehicles, numerous other propellant combinations are in common… Read More »Rocket Physics, Extra Credit: Rocket Fuels

“Rocket science is tough, and rockets have a way of failing.” – Sally Ride, NASA astronaut To go to Mars, we need rocket science. But why is rocket science so hard? In this series, Rocket Physics, the Hard Way, we… Read More »Rocket Physics, the Hard Way: The Tyranny of the Rocket Equation
2020 has been, to say the least, a difficult year for humanity. However, it has also been marked by great achievements in space exploration; a testament to our relentless pursuit for knowledge despite adversity. Before we enter 2021, let’s take a look at the year’s highlights in space exploration.
Last month, scientists confirmed the presence of multiple subsurface lakes under glaciers at the Martian south pole. How were these lakes found and why do they matter? Let’s dive into geophysics, astrobiology, and chemistry with this infographic!

Access to energy is arguably the most important indicator of a civilization’s development. On Mars, having access to energy can mean the difference between life and death – not only is it necessary to power life support systems, but it… Read More »ISRU Part III: How to Generate Energy on Mars
In Part I, we discussed making the essentials for life on Mars: fuel, oxygen, and water. After the initial exploration phase, the construction of permanent settlements and structures will begin to become a priority. When humanity settles Mars, Martian architects… Read More »ISRU Part II: How to Make Construction Materials on Mars
Of the plethora of acronyms in Mars exploration circles, one in particular forms the cornerstone of many Mars and Moon exploration plans: In-Situ Resource Utilization, or ISRU. It is key to establishing a permanent human presence beyond Earth, and both… Read More »ISRU Part I: How to Make Fuel, Oxygen, and Water on Mars
