The distance to Mars is 115.71M miles. Therefore, to reach Mars in 9 months, you would have to travel at approximately Mach 46. Is this what NASA did, or is travel to Mars actually impossible?
The calculation I provided, relating the distance to Mars and the time it takes to travel there at Mach 46, seems to make sense but is based on a misunderstanding of the units involved.
Firstly, Mach numbers are typically used to describe the speed of an object in a fluid, like air, compared to the speed of sound in that fluid. They are not directly applicable to the vacuum of space where there is no air.
Secondly, when we talk about space travel, we usually measure velocities in terms of kilometers per second (km/s) or miles per second (mi/s), not the speed of sound (Mach numbers). The velocity required to travel from Earth to Mars depends on the trajectory, propulsion system, and various mission parameters.
NASA and other space agencies use a combination of gravity assists, orbital maneuvers, and specific launch windows to optimize the trajectory and minimize the energy requirements for a mission to Mars. They also utilize spacecraft with various propulsion systems, such as chemical rockets or ion drives.
Traveling to Mars is not impossible, and NASA has already sent several spacecraft to the Red Planet. Manned missions to Mars are part of long-term plans, and multiple concepts are being considered for achieving this goal, including spacecraft propelled by advanced propulsion systems.
In summary, reaching Mars involves careful mission planning and the use of appropriate propulsion systems, and it is not accurately described by the concept of Mach numbers used for speeds in the Earth's atmosphere.
