Few institutions have shaped humanity’s understanding of space quite like NASA. Since its founding in 1958, the agency has launched hundreds of missions, but only a handful fundamentally changed science, engineering, or human history.

Some placed humans on the Moon. Others transformed astronomy, revealed hidden worlds across the Solar System, or even ventured beyond the Sun’s influence. Here are 15 NASA missions whose legacy continues to shape science and exploration today.

1. Project Mercury (1958-1963)

NASA’s first human spaceflight program proved that Americans could survive and operate in space. Alan Shepard became the first American in space in 1961, while John Glenn became the first American to orbit Earth a year later, laying the groundwork for every crewed mission that followed.

2. Project Gemini (1961-1966)

Before astronauts could reach the Moon, NASA had to master orbital rendezvous, docking, long-duration spaceflight, and spacewalks. Gemini accomplished all of those objectives, becoming the technological bridge between Mercury and Apollo.

3. Apollo 11 (1969)

Perhaps no mission changed history more profoundly. Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon while Michael Collins orbited overhead. Apollo 11 demonstrated that humanity could travel to another celestial body and safely return home, inspiring generations of scientists and engineers.

4. Skylab (1973-1979)

America’s first space station proved humans could live and work in space for months at a time. Crews conducted hundreds of experiments in medicine, solar physics, and Earth observation, paving the way for the International Space Station decades later.

5. Viking 1 (1975-1982)

When Viking 1 landed safely on Mars in 1976, it became the first successful mission to operate on the Martian surface. It returned the first images from the ground, analyzed Martian soil, and conducted pioneering experiments searching for signs of life.

6. Voyager 1 and Voyager 2 (1977-Present)

Originally designed to explore the outer planets, the twin Voyager spacecraft delivered humanity’s first close-up views of Jupiter, Saturn, Uranus, and Neptune. Both continue operating today, with Voyager 1 becoming the first human-made object to enter interstellar space.

7. Space Shuttle Program (1981-2011)

The Space Shuttle transformed access to low Earth orbit by introducing partially reusable spacecraft. Shuttle missions deployed and serviced satellites, launched the Hubble Space Telescope, assembled much of the International Space Station, and flew 135 missions over three decades.

8. Hubble Space Telescope (1990-Present)

Hubble revolutionized modern astronomy. Its observations helped refine the age of the Universe, study black holes, discover thousands of galaxies, and capture some of the most iconic images ever taken from space. More than three decades later, it continues producing groundbreaking science.

9. Mars Pathfinder (1997)

Pathfinder introduced the world to Sojourner, the first rover to operate on another planet. The mission demonstrated that relatively low-cost robotic exploration could deliver enormous scientific returns and paved the way for the sophisticated Mars rovers that followed.

10. Cassini-Huygens (1997-2017)

Cassini transformed our understanding of Saturn and its moons. It revealed water-rich plumes erupting from Enceladus, explored Titan’s methane lakes, and showed that icy moons may possess environments capable of supporting life.

11. Spirit and Opportunity (2003-2019)

Expected to survive only 90 Martian days, the twin rovers rewrote expectations. Opportunity operated for nearly 15 years, discovering overwhelming evidence that liquid water once flowed across Mars, dramatically reshaping scientific understanding of the planet’s history.

12. Curiosity (2011-Present)

Curiosity’s mobile laboratory confirmed that ancient Mars once possessed lakes, rivers, and the chemical ingredients necessary for microbial life. It continues investigating how the planet evolved from a wetter world into today’s cold desert.

13. James Webb Space Telescope (2021-Present)

Built to succeed Hubble, the James Webb Space Telescope has observed some of the earliest known galaxies, analyzed exoplanet atmospheres, and provided unprecedented infrared views of the cosmos. Its discoveries are already reshaping astronomy and cosmology.

14. Perseverance and Ingenuity (2020-Present)

Perseverance is searching for signs of ancient microbial life in Jezero Crater while collecting samples for future return to Earth. Its companion, Ingenuity, became the first aircraft to achieve powered, controlled flight on another planet, opening an entirely new chapter in planetary exploration.

15. Artemis I (2022)

More than 50 years after Apollo, Artemis I successfully tested NASA’s Orion spacecraft and Space Launch System during an uncrewed mission around the Moon. It marked the beginning of NASA’s Artemis program, which aims to return astronauts to the lunar surface and eventually support human missions to Mars.

From the Moon to interstellar space

NASA’s greatest missions have done far more than achieve technical milestones. They have expanded humanity’s understanding of the Universe, transformed engineering, and inspired generations to pursue science and exploration. With programs such as Artemis, Europa Clipper, and future Mars missions on the horizon, the next history-making NASA mission may already be on its way.

A new industrial complex in China’s Shandong province is beginning production rollout with a specific goal. Manufacturing batteries designed to store electricity for longer periods and support increasingly renewable power grids.

HiTHIUM held the production rollout ceremony for its Heze Base on August 7 in Heze Luxi New Area. The company describes the facility as the world’s first integrated industrial park dedicated exclusively to long-duration energy storage (LDES).

Unlike conventional battery plants focused primarily on cells, the Heze project brings together battery-cell manufacturing, materials production and energy-storage system integration. The planned facility covers approximately 80 hectares, with total investment across the industrial chain exceeding RMB 13 billion.

Why long-duration storage matters

Solar and wind power can produce large amounts of electricity when conditions are favorable, but generation does not always coincide with demand. Energy storage allows excess electricity to be stored and released later, helping balance the grid. LDES is intended to extend that capability over longer periods. For example, stored electricity could be released after solar generation falls in the evening or during longer periods of low renewable output. That makes the technology increasingly relevant as power systems add more variable renewable generation.

A battery factory built around LDES

The Heze Base uses a whole-industry-chain approach, covering LFP battery cells, modules and system integration, new materials and upstream raw-material processing. The facility is also designed around very large-capacity battery products. HiTHIUM says its fifth-generation intelligent manufacturing lines can produce more than 15 GWh per production line, while the company is developing thousand-ampere-hour-class cells for LDES applications.

Larger-capacity cells can potentially reduce the number of individual cells and connections needed in a large storage installation, simplifying parts of system construction. HiTHIUM’s earlier LDES products include a 1,175 Ah cell, which the company says entered mass production in 2025.

Automating storage production

The factory itself is designed as a highly automated manufacturing operation. HiTHIUM says its fifth-generation production lines have an automation rate exceeding 95% and incorporate more than 1,000 quality-control checkpoints, including AI-powered visual inspection.

According to the company, the new production system reduces floor space required per GWh by 50%, production manpower by 58%, and manufacturing energy consumption by 13% compared with its previous generation. HiTHIUM also reports a 200% improvement in production efficiency.

These figures are company-reported comparisons, but they highlight an important part of the LDES race: reducing costs will depend not only on battery chemistry, but also on manufacturing efficiency.

From cells to complete storage systems

The Heze Base is intended to take the battery manufacturing process from raw materials all the way through to finished, containerized energy-storage systems. That integrated approach matters because grid-scale storage is more complicated than simply installing large numbers of battery cells. Cells must be assembled into modules and systems, with the finished equipment incorporating the components and controls required for large-scale energy storage.

HiTHIUM says the Heze rollout marks a new phase focused on scaled manufacturing and delivery of LDES products. The significance of the project ultimately goes beyond one factory. As renewable generation expands, electricity grids need increasingly capable ways to shift power across time. The growth of dedicated LDES manufacturing suggests battery companies are now preparing for a market where storing electricity for longer periods could become just as important as generating it.
