¿Cuáles son los mayores desafíos que enfrenta la exploración espacial en la actualidad?<end_of_turn>
<start_of_turn>model
Space exploration faces several significant challenges, both technological and financial. Some of the biggest hurdles include:

Developing new propulsion technologies: Current rockets are limited in their range and speed, making it difficult to travel to distant destinations like Mars. Researchers are exploring new technologies like ion drives and nuclear thermal rockets, which offer the potential for faster and more efficient travel.
Protecting astronauts from radiation: Astronauts traveling to space are exposed to high levels of radiation, which can pose serious health risks. Developing effective radiation shielding and mitigation strategies is crucial for long-duration missions.
Developing closed-loop life support systems: Spacecraft need to be self-sufficient, providing breathable air, water, and food for astronauts on long journeys. Creating efficient and reliable closed-loop life support systems remains a significant challenge.
Reducing the cost of space travel: Launching and operating spacecraft is expensive, limiting the scope and frequency of missions. Finding ways to make space travel more affordable is essential for expanding exploration efforts.
Addressing the ethical and legal complexities of space exploration: Issues like resource ownership, space debris mitigation, and the potential for extraterrestrial life raise complex ethical and legal questions that need careful consideration.<end_of_turn><eos>
