U of A Space Science is Reaching New Heights!

Dr. Adesida is studying the effects of microgravity on joint cartilage health by using analogue systems here on earth, and is hoping to detect pathways involved in the development of osteoarthritis. When asked why he has focused on microgravity environments in particular for his research, he very relatably laughs, “I guess I'm a space geek”. Citing his love of Star Trek (also very relatable) as a catalyst for considering space environments for his research, he highlights the importance of movement and the effects of microgravity on joint health and cartilage. On earth, you’re constantly moving, “...but in space, you don’t have mechanical movement. Because you’re under low gravity there’s nothing to keep your feet on the ground”.

Dr. Komarova is aiming to understand the nature of bone mass and structure under the context of microgravity, which is incredibly relevant to human space travel. It has been known since the 1970s that astronauts lose bone mass in space, it is one of the most significant risks to astronaut’s health. Her experiments are also looking at the effects of radiation on bone mass and density. The amount of bone mass lost per month is about 1%. “It’s non-linear though”, Dr. Komarova assured. “Its not as if you went to space for 100 months you would lose all your bones”. Examining this relationship, and the variable degrees of bone mass recovery upon an astronaut’s return to Earth is a pressing concern for both the CSA and NASA, as longer spaceflights and lunar missions are being planned.
