- Space Science and Technology
Space is fascinating! Space is huge. The universe is bigger than we can imagine. The universe is so big that stars more massive than our sun and even entire galaxies look like tiny points of light because they are so far away from us.
Space contains every bit of matter and energy that has ever existed, but most of it is completely empty. When we talk about deep space, we usually mean the vast empty regions between planets.
Space can be beautiful. Our telescopes can see the beautiful and colorful shapes of planets, stars, galaxies, and nebulae.
Space can be dangerous. In deep space, without protection, we would die instantly. Our home Earth travels through space, and its atmosphere forms a cozy blanket between us and the cold and other dangers of deep space.
On July 20, 1969 at 20:17 UTC, Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin formed the American crew that successfully returned the Apollo Lunar Module Eagle to Earth. Six hours and 39 minutes later, at 02:56 UTC on July 21, Armstrong became the first person to set foot on the lunar surface; Aldrin followed 19 minutes later.
The moment Armstrong stepped onto the lunar surface, the world was filled with awe, pride, and amazement. The moon landing was an exception, not an end in itself but a means to demonstrate America’s extraordinary capabilities.
The next 50 years will be very different. Falling costs, new technologies, Chinese and Indian ambitions, and a new generation of entrepreneurs herald a bold era of space development. Tourism will almost certainly lead to rich and better communications networks for all; in the long term, it may involve mineral extraction and even mass transportation.
Space will increasingly feel like an extension of Earth - an arena not just for governments but also for businesses and individuals. But to fulfill that promise, the world needs a system of laws to govern space—in peacetime and in war.
- Earth Science
Earth science is the study of the structure, properties, processes and biological evolution of the Earth over 4.5 billion years. Understanding these phenomena is critical to sustaining life on Earth. An expanding world population requires more resources; faces increasing losses from natural disasters; and releases more pollutants into the air, water, and land.
Sustaining our existence requires a scientific understanding of the natural materials and processes that connect the geosphere, hydrosphere, atmosphere and biosphere. On the Earth's surface where these environments intersect, life thrives or fails.
In general, the term "earth science" usually includes the study of the earth's atmosphere (meteorology or atmospheric science), the water that flows up and down the surface of the continents (hydrology), and the earth's oceans (oceanography or marine science). Today, we live in a time when the Earth and its inhabitants face many challenges. Our climate is changing, and this change is caused by human activity.
Geoscientists recognize the problem and will play a key role in efforts to address it. We also face the following challenges: Develop new energy sources with minimal climate impact; find new metals and other mineral resources as known resources are depleted; and, determine how Earth's growing population lives and avoids volcanic activity, earthquakes, mountains Landslides, floods and other serious threats.
These are just a few of the problems for which solutions rely on a deep understanding of Earth science.

- Atmospheric Science
Atmospheric science is the study of weather analysis and predictability, climate and global change, atmospheric circulation associated with weather systems and their impact on Earth, air quality and other atmospheric processes that affect us.
Atmospheric science discoveries and understanding are critical to our resilience and preparedness to address the most pressing challenges facing our atmosphere-dependent systems.
The main branches of atmospheric science are:
- Meteorology and atmospheric dynamics involves the study of the movement of air that leads to thunderstorms, frontal systems, hurricanes, and tornadoes.
- Atmospheric physics applies the principles of physics to the study of atmospheric processes such as cloud formation, light scattering and energy transfer.
- Atmospheric chemistry applies chemical principles to study atmospheric processes such as air pollution, ozone depletion and aerosol formation.
Climate science studies changes in weather statistics from seasons to millennia and beyond, addressing phenomena such as El Niño, global warming, and ice ages.
- Ocean Engineering
The ocean has long been recognized as an essential part of our global environment. Oceans cover more than 70% of the Earth's surface and directly or indirectly affect all life on Earth.
Future ocean engineering focuses on sustainability and minimizing environmental impact. This include using eco-friendly materials and designs, and developing new technologies to protect coastlines and marine life.
Ocean engineering involves the development, design and analysis of man-made systems that can operate in offshore or coastal environments. Such systems could be used in transportation, recreation, fishing, extraction of oil or other minerals, and recovery of heat or wave energy, among others.
Some systems are bottom-mounted, especially those at shallower depths; others are mobile, such as ships, submersibles or floating rigs. All systems should be designed to withstand harsh environments (wind, waves, currents, ice) and operate efficiently while remaining environmentally friendly.
Ocean engineering research, as a major research field of mechanical engineering, needs to meet the core requirements of ocean hydrodynamics and ocean structure. Disciplines supporting ocean engineering include: coastal engineering, marine renewable energy, ocean acoustics, materials and manufacturing, control and robotics, continuum mechanics, dynamical system theory, design methods, mathematical analysis and statistics.
