Flames tend to be spherical in the absence of gravity because there is no gravitational force to create the buoyant convection that lifts hot gases and pulls cooler air in. In microgravity, the flame expands equally in all directions, forming a sphere. This differs from Earth, where gravity pulls denser, cooler air down to the flame, which rises as it heats, resulting in the typical teardrop shape. On Earth, the flame's teardrop shape is due to buoyant convection. Hot, less dense air rises, and

46K views · 2.8K reactions | Is there oxygen on Mars? Technically yes, but it’s nothing like the amount we have on Earth. So breathing is out of the question. However, there IS a lot of carbon dioxide (CO2) on Mars. Now, a new technology — MOXIE — has proven that we can convert Martian CO2 into oxygen for use by future explorers.
