William P. MacCracken's first pilot license.

Introduction

From the first glider flight to the first powered flight, aviation pioneers have paved the way for remarkable innovations in flight. At NASA, our pilots conduct research, study wildfires, and support unmanned aircraft missions. In fact, out of the 360 astronauts who have been selected, 191 of them have been pilots!  

The History of Pilot Certificates

In 1804, Sir George Cayley, known by some as the “Father of Aviation,” successfully flew the first glider with a pilot. Years later in 1903, the Wright Brothers became the first to achieve powered manned flight in North Carolina.  

In 1927 the U.S. Government introduced pilot certificates, or licenses, to regulate flying and keep people safe. The first license was given to Willam P. MacCracken Jr.  

Not everyone was allowed receive a U.S. pilot’s license in the early days. In 1919 Bessie Coleman was denied flight training due to both her skin color and gender. She moved to Paris after learning that there were flight training opportunities for her there. In 1921, she became the first African American woman to obtain an international pilot’s license.  

In June of 1927, Phoebe Omlie became the first woman to obtain a U.S. pilot’s license. Six months later James Banning became the first African American to get a U.S. license. These pilots paved the way for a future where everyone, regardless of their gender or skin color, is allowed to fly.

What makes a pilot?

Flying takes focus, determination, and commitment to lifelong learning.

To become a pilot, you must pass flight tests and a medical exam to make sure you are fit to fly. Certain medical conditions may disqualify someone from obtaining a license, but in some cases special permits are issued that allow those with certain health challenges to fly in specific planes or conditions.

In 2008 Jessica Cox became the first licensed pilot to fly without arms. She was born with a rare birth defect but did not let that stop her from flying with her feet! In 2009, Capt. Ryan McGuire became the first airman to complete Air Force pilot training after losing a leg. There are even options for the deaf, allowing them to pursue flight training.

How does flight training work?

Flight training takes place on the ground and in the air. Ground school teaches students how the plane works and the flight rules. In-the-air training teaches students how to fly the plane. Students fly specific hours long distance, at night, and by themselves (solo). Additional flight training qualifies pilots to fly using instruments only, more complex and larger aircraft, specialty aircraft, and to become flight instructors themselves.   

After training some pilots, like commercial airline pilots, wear uniforms that display their rank. Business pilots and military pilots wear special uniforms, too.  

Airline pilots wear stripes on the wrist of their coats, and stripes on the shoulders of their shirts. Below are the typical markings that show airline pilot levels of command:

  • Captains are the highest in command and wear four stripes. They sit in the left seat and are in charge of making decisions. Sitting in the left seat of the aircraft puts them in charge of the aircraft.
  • First officers are second in command, and wear three stripes. They sit in the right seat and have their own tasks to complete. They assist the Captain and also fly the aircraft at times. They can also take over if needed.
  • Second officers are third in command, often working very long flights. When they fly they wear two stripes.  
  • Third officers or training pilots are fourth-in-command, and they wear one stripe.

Pilot Flight Logs

Pilot flight logs, which have been around in one form or another since the beginning of flight, have served several purposes. Today, pilot logbooks are used by aviators to provide a record of their flights, including current and accumulated flight time, number and locations of takeoffs and landings, as well as unique operating conditions and certifications. For the pilot in training, a flight log shows accumulated practice, certifications, and special endorsements. In the early days of flight, flight logs were also used by air mail carriers, barnstormers, and others to make sure they were paid properly.

The Wright brothers kept fastidious notes and records of all flights and aircraft developments, mostly in the form of notebooks, diaries, and drawings. Britain’s Royal Corps utilized a more formal flight log format in 1912, adapted from ship logs, to record flight details. In the United States, official guidelines for flight, including logging flights, were first introduced with the Air Commerce Act of 1926. Whatever format is used, details such as aircraft flown, time aloft, distance flown, route, weather conditions, and other details about the flight are included, along with any problems faced along the way.

As flight and requirements increased in complexity, logbooks split into separate logbooks for pilots and the aircraft itself: today you will find both pilot logbooks, which are personal logs of a pilot’s flights, and aircraft logbooks which contain details about the aircraft’s flight, no matter who flies the craft.

Modern day flight logs are digital, although some pilots still prefer to keep records in a paper logbook. NASA’s Mars Ingenuity helicopter flights, the first flights on another planet, are recorded in the “Nominal Pilot’s Logbook for Planets and Moons.” If you want to keep up-to-date on Ingenuity’s flight log entries, you can find them here: https://mars.nasa.gov/technology/helicopter/#Flight-Log

NASA will host a public event featuring three crew members from the agency’s SpaceX Crew-11 mission at 11 a.m. EDT Monday, June 1. The event, which takes place during the crew’s standard postflight visit, will be held in the Webb Auditorium at NASA Headquarters in the Mary W. Jackson building, 300 E. Street SW in Washington.

The crew members, including NASA astronauts Zena Cardman and Mike Fincke and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, will discuss their recent 167-day mission aboard the International Space Station, where they conducted a wide range of science experiments to benefit life on Earth and advance human space exploration as part of International Space Station Expedition 73/74.

The Crew-11 mission lifted off on Aug.1, 2025, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The crew’s SpaceX Dragon spacecraft docked to the orbital outpost on Aug. 2.

During their mission, the three astronauts, along with crewmate Roscosmos cosmonaut Oleg Platonov, traveled nearly 71 million miles and completed more than 2,670 orbits around Earth. The Crew-11 mission was Fincke’s fourth spaceflight, Yui’s second, and the first for Cardman and Platonov. Fincke has logged 549 days in space, ranking him fourth among all NASA astronauts for cumulative days in space. The crew members returned to Earth on Jan. 15, splashing down off the coast of San Diego.

Along the way, Crew-11 logged hundreds of hours of research, maintenance, and technology demonstrations. The crew members also celebrated the 25th anniversary of continuous human presence aboard the orbiting laboratory on Nov. 2, 2025. Research conducted aboard the space station advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars.

Media interested in attending the event must RSVP by 8 a.m., June 1, by emailing the NASA Headquarters newsroom at hq-media@mail.nasa.gov. NASA’s media accreditation policy is online. Based on the crew’s schedule, NASA will not be able to accommodate interviews.

This opportunity also is part of NASA’s Frontiers Forum: Voices Shaping the Future of Space speaking series designed to convene bold thinkers and senior leaders at the forefront of exploration and innovation. The series will spotlight mission-critical priorities from advancing the Artemis campaign and strengthening commercial partnerships to shaping the future workforce and accelerating breakthrough technologies.

NASA’s Roman Space Telescope Primary Mirror Gets Last Look

Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have completed their final inspection of a key element for the agency’s Nancy Grace Roman Space Telescope: the primary mirror. This 7.9-foot (2.4-meter) mirror will collect and focus light from cosmic objects near and far, helping Roman capture stunning panoramas of space.

The primary mirror for NASA’s Nancy Grace Roman Space Telescope has passed its final inspection. On May 20 and 21, engineers at NASA’s Goddard Space Flight Center in Greenbelt, Md., confirmed that no specks fell onto the mirrors during testing and that there are no defects in the coating or alignment. With this milestone complete, the primary mirror is ready for its next view: space.

“The Roman engineering team laid eyes on the telescope for the final time before it, in turn, becomes the eyes of humanity, revealing the wonders of the cosmos,” said J. Scott Smith, the Roman telescope manager at NASA Goddard. “It is a profoundly humbling moment to witness the culmination of hard work from so many dedicated individuals, teams, and partner organizations, including L3Harris.”

On May 20, engineers turned the Roman observatory onto its side and deployed the “hood” that will be stowed for launch to protect the mirror. Then the team conducted a meticulous visual inspection to ensure no specks fell onto the mirrors during testing and confirm there are no defects in the coating or alignment.

“We developed a method of using a high-resolution camera equipped with a very powerful zoom lens to do a multi-purpose inspection,” said Bente Eegholm, optics lead for Roman’s Optical Telescope Assembly at NASA Goddard. “The mirror passed with flying colors, keeping the mission on track for an early September launch.”

The team carefully observed the optics along the path light will follow to the Wide Field Instrument detector array and confirmed it remains in proper alignment following the observatory shake test.

“In order to gather very sensitive measurements of objects strewn throughout space, all of Roman’s components have to be ultraprecise,” Eegholm said. “The primary mirror certainly delivers on that precision.”

Roman’s primary mirror sports a layer of silver less than 400 nanometers thick — about 200 times thinner than a human hair. The silver coating was specifically chosen for Roman because of how well it reflects near-infrared light. By contrast, the Hubble Space Telescope’s mirror is coated with layers of aluminum and magnesium fluoride to optimize visible and ultraviolet light reflectivity. Likewise, the James Webb Space Telescope’s mirrors have a gold coating to suit its longer wavelength infrared observations.

The Roman mirror is so finely polished that the average bump on its surface is only 1.2 nanometers tall — more than twice as smooth as the mission requires. If the mirror were scaled up to Earth’s size, these bumps would be just a quarter of an inch high.

Since it’s made of a specialty ultralow-expansion glass, the mirror will resist flexing, which can happen to materials during temperature changes (like going from balmy Earth conditions to the deep freeze of space). This preserves Roman’s image quality, because if the primary mirror changed shape, it would distort the images from the telescope.

“We’re really proud of the amazing optical system we’ve delivered for the Roman mission alongside our partners at L3Harris,” said Josh Abel, lead Optical Telescope Assembly systems engineer at NASA Goddard. “Now that it’s assembled, aligned, and all shined up, we’re ready to go.”

Now, the Roman team is preparing to ship the observatory to the launch site at NASA’s Kennedy Space Center in Florida in the coming weeks. NASA expects the mission to begin returning incredible cosmic vistas within several months after launch.
