NASA Remembrance Day
NASA Day of Remembrance honors the astronauts who lost their lives while advancing human space exploration, particularly the crews of Apollo 1, Space Shuttle Challenger, and Space Shuttle Columbia. The annual observance provides an opportunity to remember their lives and contributions while reflecting on the importance of safety, learning, teamwork, and continuous improvement in spaceflight. For STEM, the day offers a meaningful way to explore aerospace engineering, space science, human factors, risk management, and the responsibility scientists and engineers carry when designing complex systems.
How it Started…
NASA established its annual Day of Remembrance to honor members of the NASA family who lost their lives in the pursuit of exploration and discovery. The observance particularly remembers three major tragedies in the history of the U.S. human spaceflight program.
- Apollo 1 — January 27, 1967: Astronauts Virgil “Gus” Grissom, Edward White II, and Roger Chaffee died in a fire during a preflight test.
- Space Shuttle Challenger — January 28, 1986: Astronauts Francis “Dick” Scobee, Michael Smith, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis, and Christa McAuliffe died when Challenger was lost shortly after launch.
- Space Shuttle Columbia — February 1, 2003: Astronauts Rick Husband, William McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark, and Ilan Ramon died when Columbia was lost during reentry.
NASA uses the observance both to honor those lost and to reinforce the importance of learning from the past as future missions are developed.

STEM From’s Take
Our Perspective…
Space exploration represents some of humanity’s most ambitious science and engineering. Sending people into space requires thousands of individuals—from astronauts and aerospace engineers to physicians, technicians, software developers, scientists, mission controllers, and safety specialists—to work together within extraordinarily complex systems.
At STEM From, NASA Day of Remembrance provides an important opportunity to discuss a side of STEM that students don’t always encounter: responsibility. Engineers and scientists don’t simply design something and hope it works. They test, question assumptions, communicate concerns, evaluate risks, investigate failures, and continually improve systems. Remembering those who were lost also means recognizing our responsibility to learn from the past.
The Significance and Why We Care…
The astronauts remembered on this day dedicated their lives to exploration, discovery, service, and expanding humanity’s understanding of what is possible. Their contributions remain part of the history of human spaceflight and continue to influence how future missions are designed and operated.
The day also demonstrates why safety culture matters in STEM. Complex systems can fail for technical, organizational, or human reasons—and sometimes through a combination of them. Engineers and leaders must create environments where concerns can be raised, evidence is taken seriously, assumptions are challenged, and safety remains central to decision-making.

Fun Fact
NASA’s human spaceflight missions involve far more careers than astronauts alone. Engineers, physicians, flight controllers, scientists, programmers, technicians, mathematicians, psychologists, meteorologists, communications specialists, and many other professionals contribute to getting a spacecraft and its crew safely from Earth to space—and back again. That means a student fascinated by space doesn’t necessarily have to become an astronaut to build a career exploring it.
STEM From Activity
The People Behind a Space Mission
Ask students to imagine NASA is preparing for a mission to Mars. Create a mission team that includes:
- Aerospace engineers
- Software engineers
- Physicians
- Scientists
- Mission controllers
- Robotics engineers
- Psychologists
- Communications specialists
- Safety engineers
- Astronauts
Have students investigate one career and answer:
What does this person do? → What skills do they need? → What could go wrong without their expertise? → How do they contribute to mission safety?
The activity demonstrates that successful exploration depends on collaboration across many STEM careers.
Discussion Questions
- Why is remembering past missions important for future exploration?
- What responsibilities do engineers have when people’s lives depend on their designs?
- Why is communication important when someone identifies a potential safety concern?
- What can scientists and engineers learn when something goes wrong?
- Why do spacecraft need backup systems?
- How does teamwork contribute to mission safety?
- What STEM careers contribute to human spaceflight besides astronauts?
- How can future generations honor explorers while continuing to push the boundaries of discovery?
