What does an electrician do?

Electricity powers the world, and electricians are the ones who get it where it needs to go. An electrician is an expert who is trained to make sure electrical systems and equipment are installed safely and working correctly. Electricians are involved in a variety of systems, including power, lighting, communications, and more – anything that needs electricity to run.

While electricians ensure systems and equipment have the power they need, electrical technicians focus on building, modifying, or testing electronic devices.

What are some of the different types of work electricians and electrical technicians do at NASA?

At NASA, electricians keep the lights on and the power flowing for rocket launches, scientific research, and everything in between. Their skills support engineers and scientists in building and testing spacecraft, aircraft, satellites, telescopes, and the equipment that makes human spaceflight possible. Electricians make sure all facilities and equipment have the power and functionality they need to be safe and ready to support NASA’s missions.

Electrical technicians at the agency help bring big ideas to life. They might build and wire control systems, connect tiny sensors to circuit boards, or write the software to make a device work in a specific way. They also test instruments in conditions that mimic space – extreme temperatures, intense vibrations, and even a vacuum – to make sure they will survive and perform well during their missions. Technicians use specialized tools, earn certifications, and work with incredible precision.

Being an electrician or electrical technician at NASA is careful, hands‑on work carried out with expertise. Because space hardware is headed to places like low-Earth orbit, the Moon, or even Mars, every detail has to be perfect.

What are the different certification levels for electricians?

The information below is a general overview of the career path of an electrician. Specific guidelines for these roles vary from state to state. It’s important to look up the license requirements in your state.

• Apprentice electrician: This four-year job training program provides an entry into the industry. An apprentice works as an assistant to an experienced supervisor, gaining vital hands-on experience to move ahead as an electrician.

You can also gain useful experience through part-time work, or shadowing electricians on the job.

What skills will I need to be a successful electrician?

Technical skills focus on the basics – how electricity works, how to stay safe, and how to read schematics and wiring diagrams. Some jobs also call for special hands‑on abilities, like soldering tiny components, putting together cables, or even having some familiarity with chemistry.

Being curious, open‑minded, and a good communicator matters, too. Any time you’re building or improving a device, you must understand who will use it and what they need it to do. Asking questions, sharing ideas, and being able to take feedback are essential to consistently building systems and devices that work well.

Advice from NASA electricians and electronic technicians

“As an aerospace technician, you have the opportunity to make a big difference. You can make a really big impact.” – Christopher Johnson, aerospace electrical engineering technician, NASA’s Kennedy Space Center in Florida

“What I wish I knew in high school is how many opportunities there are for electricians. I didn’t realize how big of a scale it really was. Everything needs electricity, and the sky’s the limit on what you can do with it. NASA needs electricians for everything from their testing campaigns to keeping their facilities running.” – Levi James, electrician apprentice, NASA’s Glenn Research Center at Armstrong Test Facility in Sandusky, Ohio

“It’s so gratifying when somebody comes in and says, ‘Hey, we want to build this, but it looks really difficult,’ and we say, ‘Yeah, it looks difficult, but we can do it’ – and we build it and then we hand it over to them, and then we’re on to the next thing. It’s a challenge, and I’m telling you, it is just so fun.” – David McClaeb, electronic technician, NASA’s Goddard Space Flight Center in Greenbelt, Maryland

The Moon appears half-illuminated in this photo captured by the Artemis II crew on flight day 6. The terminator – the difference between light and darkness – provides a stark contrast and even greater perspective of the Moon’s rocky, uneven, and otherworldly surface features. The near side, which is what we can see from Earth, appears in the dark gray regions at the top of this image.

Jason Peterson’s responsibilities for NASA’s Artemis II mission went beyond his usual role as the range operations manager at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

For Peterson, working at NASA is a surreal full-circle moment.

“I grew up in DeLisle, Mississippi, right down the road from NASA,” said Peterson. “You would hear NASA testing, the windows would shake, and you knew they were out there. Not in a million years would I have ever dreamed I would work with NASA.”

His career journey took a few turns before reaching the space agency.

“I got out of school, welded, went to college and then to the Air Force. The path to NASA really started to develop from there,” said Peterson.

Peterson spent 24 years in the U.S. Air Force and Air National Guard, working in airfield and air-to-ground range operations, followed by a few years working as an aircraft dispatcher at Airbus Final Assembly Line.

Peterson credits his military experience with preparing him for the 12-to-16-hour workdays that helped bring the Artemis II test flight around the Moon and into view for audiences around the world.

He supported the team responsible for delivering video and communication feeds for the launch of NASA’s SLS (Space Launch System) rocket with the Artemis II crew aboard the Orion spacecraft, and then splashdown in the Pacific Ocean.

During the nearly 10-day mission, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth.

Aboard the USS John P. Murtha, Peterson was the first on the ship to spot the capsule returning with the crew.

Peterson operated one of six cameras providing live coverage by using a high‑resolution, multi‑sensor system with thermal capabilities. Using the ship’s heading and Orion’s predicted trajectory, he located the capsule within minutes and began tracking it.

Orion entered Earth’s atmosphere at about 400,000 feet above the planet’s surface, traveling nearly 35 times the speed of sound and about 1,956 statute miles from its splashdown point off the coast of California. Peterson tracked Orion from the release of the small parachutes that first slow and steady the capsule, through the main parachutes opening, and all the way to splashdown.

“You are fully locked in, keeping it centered, in focus, and steady,” said Peterson.

Peterson’s focus on the mission began weeks earlier at NASA’s Kennedy Space Center in Florida.

In the days leading to launch, Peterson worked with the team running full systems checks, staging communications gear, and preparing drones and fixed‑wing camera assets. He helped configure and operate the systems that ensured live video flowed from the launch pad, the crowds, and surrounding air and ground platforms.

On April 1, the launch day of Artemis II, the team unloaded and set up high‑resolution sensors, connection terminals, routers, monitors, fiber lines, and drone equipment. They flew drones to capture crowd scenes and aerial views before liftoff.

As the SLS rocket launched, Peterson’s full attention was on positioning the drone and maintaining the shot.

“There is not much time to step back and take in the moment, as you are concentrating on precision,” said Peterson.

As the mission got underway, Peterson and the team packed up, returned to the facility, and downloaded the day’s footage.

The Artemis II crew were more than halfway to the Moon as Peterson arrived in San Diego on April 4. In the days leading to splashdown, the team loaded and installed high‑fidelity cameras and supporting equipment, all to help the world witness a historic milestone when the Artemis II crew returned to Earth on April 10.

Next up will be Artemis III. NASA will launch four astronauts from NASA Kennedy aboard the Orion spacecraft on the SLS rocket. Building on the successful Artemis II crewed test flight in April, Artemis III will pave the way for future surface missions, with experts like Peterson helping every step of the way.

The interstellar comet 3I/ATLAS carries a chemical fingerprint unlike anything in our Solar System, and it may have formed 10 to 12 billion years ago, before our Sun even existed, according to two papers published in the journal Nature.
