What are the logistical challenges in having whales be the spacefaring race. This makes senes because whales have evolved for low-gravity, which is very harmful to humans, and live in dark and cold environments. Please use as much known physics and math as possible, for example, current rate of increase of mass delivered to space, for making a high level estimation for the feasibility of getting a whale into space. Consider that the whale will need a minimum amount of water.

The idea of whales as a spacefaring race presents a host of unique logistical challenges. Let's break down the major factors:

1. Adaptation to Low-Gravity Environment: Whales, evolved for an aquatic environment, might theoretically be better suited to low gravity than land-dwelling creatures like humans. In water, whales experience buoyancy, which reduces the effect of Earth's gravity. However, space's microgravity environment is quite different from being buoyant in water. In microgravity, there's no resistance like water to help whales move or maintain their shape. Their bodies are adapted to be supported by water, and without it, they might face health issues.

2. Life Support System: Whales require a vast amount of water, which serves as their living medium. A whale in space would need a spacecraft filled with water to simulate its natural habitat. This leads to significant challenges:

   • Mass of Water: Water is heavy (1 cubic meter weighs 1 ton). A blue whale, for instance, could require thousands of cubic meters of water. Let's do a rough calculation considering a smaller whale species, like a Minke whale, which might need a minimum of 1000 cubic meters of water:

   • $Mass of Water=1000 cubic meters×1000 kg/cubic meter=1,000,000 kg$

   • Delivery to Space: Current rockets can deliver about 20-25 tons (20,000-25,000 kg) to Low Earth Orbit (LEO). Assuming the most optimistic capacity of 25,000 kg per launch, we would need:

   • $Number of Launches=25,000 kg/launch1,000,000 kg​=40 launches$

     This is for the water alone, not accounting for the spacecraft, life support systems, or the whale itself.

3. Temperature and Pressure Control: Whales are adapted to specific pressure and temperature ranges. Any spacecraft would need to simulate these conditions, which adds to the complexity and mass of the spacecraft.

4. Feeding and Waste Management: Whales consume large quantities of food and produce significant waste. Any space mission would need to address how to supply food and manage waste in a zero-gravity environment filled with water.

5. Psychological and Health Concerns: The impact of space travel on the whale's psychology and physiology is unknown. Issues like bone density loss and muscle atrophy, seen in human astronauts, could also affect whales, albeit differently due to their aquatic nature.

6. Cost and Resources: The cost of launching the required mass to space is enormous. Considering the current cost per kilogram to LEO and the mass of water and life support systems needed, the financial resources would be substantial.

7. Engineering Challenges: Designing a spacecraft that can hold a whale, water, and life support systems is an unprecedented engineering challenge. It would require innovations in materials, propulsion, and life support systems.

In conclusion, while whales have certain characteristics that might seem advantageous for space travel, the practical challenges are enormous. The mass of water needed, life support requirements, and engineering challenges make this a highly impractical endeavor with current technology and understanding of space travel.
