Challenges

A newly discovered near‑Earth object like “Impactor‑2025” grabs headlines—and for good reason.

Farming is changing fast—and the challenges keep growing. More people to feed, hotter and more unpredictable weather, strained water supplies, and shrinking soils all push agriculture to be smarter and more sustainable.

Sharks are more than ocean icons—they’re ecosystem engineers. As top predators, they help keep food webs balanced, support healthy fisheries, and signal the pulse of ocean ecosystems.

Three years on Mars sounds like a grand adventure—until you imagine what eight people will leave behind.

The Sun sends more than light and warmth—sometimes it sends surprises. Space weather (solar flares, coronal mass ejections, the solar wind) travels from the Sun to Earth and can affect people in ways both beautiful and surprising.

Synthetic aperture radar (SAR) is a different way of seeing the Earth—one that doesn’t care about daylight or clouds. I

Forecasts tell us what’s likely in the next week or two, but what if you need to plan months ahead?

Designing a home off Earth is equal parts imagination, human care, and hard engineering.

Have an idea that doesn’t fit any of the official prompts? Excellent—this is your green light to invent your own NASA‑data project.

Flowers are nature’s calendar. Each bloom marks a moment in the year — a cue for pollinators, a sign of crop readiness, a signal of changing seasons.

NASA has run decades of biology experiments in space—studies on microbes, plants, cells, animals, and people. Those experiments matter now more than ever as humans plan extended stays on the Moon and the first crewed missions to Mars.

Low Earth orbit is no longer just for national space agencies and a few research satellites. It’s fast becoming a commercial neighborhood—full of satellite constellations, hosted payloads, in‑space manufacturing ideas, and even early space‑tourism experiments.

Cities are living systems—and climate change is making them harder to manage. Rising temperatures, shifting rainfall patterns, more frequent floods and droughts, and worsening air quality all affect how people live, work, and move

Oceans are the planet’s heartbeat. From the tiniest plankton to the largest currents, they regulate climate, feed billions, and hide entire worlds beneath their surface

Huge images from space can feel like a different universe. Your phone shows millions of pixels; NASA’s telescopes and orbiters deliver billions and even trillions.

Air you can’t see can still hurt. Every year outdoor air pollution contributes to millions of deaths worldwide, and nearly everyone breathes air that sometimes exceeds safe limits

The International Space Station gives astronauts two unforgettable experiences: looking out the cupola at Earth below, and training for weightlessness in the Neutral Buoyancy Laboratory (NBL)

For a quarter of a century, NASA’s Terra satellite has been circling our planet every day, collecting a truly astonishing archive of environmental data.

Space-based missions like Kepler, K2, and TESS have revolutionised our understanding of the cosmos by discovering thousands of exoplanets—planets orbiting stars outside our solar system
