Space probes are robotic spacecraft sent into space to explore our solar system and beyond. Unlike astronauts, these machines can travel to places that are too dangerous or distant for humans. Their primary mission is (35) __________ information about planets, moons, and other celestial bodies. They are the eyes and ears of humanity in the vast emptiness of space, providing us with a close-up view of worlds we may never visit in person.

The journey of a space probe begins on Earth. First, they (36) __________ from Earth aboard powerful rockets that escape our planet's gravity. This journey can take many months or even years to complete; (37) __________, careful and precise planning is absolutely essential for mission success. Navigators must calculate the perfect path to reach the target destination millions of kilometers away.

Upon reaching its destination, a probe uses its set of scientific instruments to begin its work. Each instrument has a specific job, like taking pictures or analyzing gases. If one instrument failed, the mission controllers (38) __________ rely on the others to complete as much of the mission as possible. For scientists waiting back on Earth, getting a clear signal after such a long journey is like (39) __________.

A lead engineer once explained that the probe (40) __________ programmed to enter a 'safe mode' if it encountered an unexpected problem, protecting its valuable systems. The information it gathers is converted into a digital signal and sent back across space. These radio waves, carrying valuable (41) __________, are captured by large antennas on our planet.

Scientists then decode these signals to create images and charts. This information helps them understand a planet's weather, geology, and potential for life. Every piece of information is a vital clue in the great puzzle of the universe. The discoveries made by (42) __________ space probes have fundamentally changed our understanding of the cosmos.

As global travel becomes more accessible, a new generation of travelers is looking for more than just a place to sleep. They seek genuine connection and cultural understanding, moving away from standardized tourist experiences. This shift has ignited a debate about the best type of accommodation: the traditional, reliable hotel or the intimate, personal homestay. For teenagers planning future adventures, like a school exchange or a backpacking trip, this choice is crucial as it can fundamentally shape their perception and memory of a new destination.

A homestay, by definition, involves staying in the home of a local family. Its main appeal lies in the opportunity for deep cultural immersion. Guests can share meals with their hosts, learn about daily routines, and receive insider tips on the best local spots, far from the tourist crowds. In Vietnamese highland towns like Da Lat and Sa Pa, this model has become extremely popular. Tourists, often inspired by social media, choose to stay with local ethnic minority families to experience their unique lifestyle and traditions firsthand. This provides an authentic cultural exchange that a hotel simply cannot replicate.

However, the homestay experience is not without its challenges. It often means less privacy and sharing facilities like bathrooms. Furthermore, the rise of tourism has led to the commercialization of the concept. Some properties marketed as homestays are actually small, family-run guesthouses with little to no host interaction. They often look like traditional homes but are run purely as businesses, which can dilute the very authenticity travelers are seeking. This is where hotels have a clear advantage, offering a predictable standard of comfort, security, and privacy.

On the other hand, hotels provide a different kind of value. They guarantee a consistent level of service, professional staff, and amenities such as swimming pools, gyms, and 24-hour reception. For travelers who spend their days exploring bustling cities or trekking through challenging landscapes, the comfort and anonymity of a hotel room can be a welcome retreat. The choice is not about which option is universally better, but which one aligns with a traveler's personal priorities and expectations for their journey.

Ultimately, deciding between a homestay and a hotel depends on what you, as a traveler, want to gain from your trip. If your goal is to live like a local and forge personal connections, a well-chosen homestay is ideal. If you prioritize comfort, privacy, and guaranteed amenities after a long day, a hotel is likely the safer bet. The key is to do your research, read reviews, and understand what each option truly offers before you book.
