Space exploration is an idea that seems straightforward on paper, but when you start to think of potential challenges, you realize how complex and incredible human curiosity really is. Space exploration has its own history and timeline, but it all started with the idea that something else might exist outside of earth. Since then, space exploration has taken humans to places they have never ventured before, gaining new insight into other worlds after meeting them face-to-face. Here are six things humans cannot explore space without:

1. Spaceship and Launch System

It makes sense that a spaceship is first on the list of “things humans cannot explore space without,” but the truth is, a spaceship isn’t enough. To successfully launch into space, a system must be created to lift people and cargo into the atmosphere and safely land them back on Earth. When humans go to space, they spend the most time in their spaceships; it’s where they live and work when they’re not on missions exploring other planets or researching space. The spacecraft is also the key component of a rocket system that takes people and cargo into space. There are a few different types of spacecraft, and they tend to be categorized by the type of space they’re designed for.

2. Space Suit and Breathing System

While it’s tempting to think that space is a vacuum, it’s not. The air in the upper atmosphere of Earth is breathable. It’s very thin on the planet’s surface compared to how thick the atmosphere is in space, but still breathable for humans. But a spaceship isn’t just the vessel itself; it needs something to inhabit inside of it. That’s where spacesuits come into play, otherwise known as your vehicle for exploring space. A spacesuit is a cloth mesh that creates an airtight seal around the wearer’s body, helping keep the person alive in space because there’s no oxygen in space to breathe. And while the suits are still developing, they’re getting better and better at protecting their wearers.

3. Sensors, Tools, and Equipment

Even if a spacecraft lands on another planet or moon, humans need tools and sensors to explore areas of that planet or moon. They need to be able to see, measure, map, and document everything they encounter. Spacecrafts use state-of-the-art tools and equipment to navigate their way around space and even study other places that humans have yet to physically reach.

It’s no question that space exploration involves quite of bit of planning, which is ultimately driven by various mathematical calculations and projections. With so many known and unknown variables to account for, the complexity of these calculations is apparent. With this in mind, scientists rely on quantum algorithm design and powerful computers to gather necessary info and plan accordingly.

4. Communication Satellites

Human beings can only communicate with each other when they’re within line of sight of each other. That’s an issue when one is on the surface of a planet that’s thousands of miles away from another person. That’s where communication satellites come into play. Communication satellites are manmade satellites that circle the Earth, and they’re the only way that people on Earth can communicate with each other when they’re not within line of sight. It also means humans can communicate with astronauts in space as they fly around other planets and moons, taking pictures of new worlds, studying them, and more.

5. Navigation Satellites

If humans want to explore space, they need a way to navigate and then push on to another planet or moon. A GPS is what a human would use in an emergency, but there’s also a need for navigational satellites. Navigation satellites are artificial objects, usually in the form of satellites, that are used to help send location data. They send out signals that other GPS systems can track and use to guide their way around the planet or moon.

6. A Power Source

All of this technology, spaceships, computers, and more rely on a power source. A power source is something that provides an energy source. Humans do that through radioactivity. Power sources provide people and the things they use to explore space with every single form of energy they need, from magic power and thermal power all the way to solar energy. There are several different thermal power sources, including fossil fuels like coal and natural gas, as well as nuclear power plants. Solar power is one of the most popular forms of energy humans use because it’s renewable and clean and provides humans with a non-radioactive power source.


These are just a few of the many ways human technology has evolved. Technology evolves when the needs of people change or when new information is learned or sought after. That’s why scientists around the world continue to study the world outside of Earth. Fortunately, with constantly evolving technology and neverending human curiosity, there is still much left to learn.
