NASA announced Friday Janet Petro, center director for the agency’s Kennedy Space Center in Florida, is retiring.

Prior to joining NASA, Petro worked in a variety of military and industry positions, ultimately beginning her career at the agency in 2007 and working her way up to center director, as well as serving as acting administrator from January to July 2025.

“From the outset of her distinguished tenure at NASA, Janet has served as a profoundly influential leader, guiding both the agency and our Kennedy Space Center through some of the most significant transitions in our shared history, including playing a central role in reshaping NASA Kennedy into the nation’s premier multiuser spaceport,” said NASA Administrator Jared Isaacman. “As NASA has been charged, once again, with accomplishing the near impossible, I’m grateful for Janet for always embracing the challenge of discovering what could be and for pushing the boundaries to deliver the missions that enable NASA to lead the way into a new era of space.”

As NASA Kennedy’s 11th director, Petro manages a team of civil service and contractor employees, determining and implementing center policy and managing and executing the spaceport’s missions and agency program responsibilities. Previously, Petro served as acting director and NASA Kennedy’s deputy director. During her time as deputy director, she helped the center transition into a multi-user spaceport, leading cross-agency initiatives with the FAA (Federal Aviation Administration) and U.S. Air Force to streamline government processes and support commercial space operations to increase government efficiency and limit redundancy.

Petro also has served numerous roles at Kennedy and NASA Headquarters in Washington, including as the program executive on an agencywide initiative to restructure mission support functions, helping NASA become more efficient and effective in its work.

Outside of the agency, Petro has served in various management positions for Science Applications International Corporation, or SAIC, and McDonnell Douglas Aerospace Corporation, interfacing with NASA, U.S. military, and commercial entities on numerous aerospace and military programs.  

Petro began her professional career as a commissioned officer in the U.S. Army after graduating in 1981 from the U.S. Military Academy at West Point, New York, with a bachelor of science degree in engineering. She was in the second class of West Point graduates to include women. Petro also holds a master of science degree in business administration from Boston University’s Metropolitan College.

Petro is the recipient of numerous service and performance awards, including a President’s Distinguished executive award, and has received the astronaut-selected Silver Snoopy award for outstanding performance, contributing to flight safety and mission success. In 2018, Petro was selected by Florida Governor Rick Scott for induction in the Florida Women’s Hall of Fame, and she helped lead the senior management team awarded the 2019 Samuel J. Heyman Service to America Sammies Management Excellence Medal. She received the 2022 Dr. Kurt H. Debus Award by the National Space Club Florida Committee for her contributions to America’s aerospace efforts within the state of Florida.

Effective Friday, Kelvin Manning now is stepping into the role of acting center director, bringing more than 32 years of leadership and technical expertise. He has previously served as deputy center director.

Technicians at NASA’s Payload Hazardous Servicing Facility (PHSF) at the agency’s Kennedy Space Center in Florida offloaded eight high-efficiency particulate air (HEPA) wall modules and other ground support equipment on April 27. The equipment will support launch processing of the agency’s Nancy Grace Roman Space Telescope.

Each 1,800-pound module enhances the PHSF’s clean room systems, helping meet the telescope’s stringent cleanliness requirements during its time in the facility, where the observatory will undergo key tasks such as spacecraft fueling prior to liftoff.

Roman will observe the universe in infrared light using its Wide Field Instrument and a Coronagraph Instrument technology demonstration. Its wide field of view will produce panoramic images that help astronomers investigate some of the greatest mysteries in the cosmos, including why the universe’s expansion appears to be accelerating.

By using multiple complementary techniques, Roman will chart how the universe has evolved over cosmic time and provide new insights into the nature of dark energy. Roman also will advance the study of exoplanets and map the structure and distribution of normal matter and dark matter across space and time.

Earth’s magnetic field is like a powerful trap. It lures electrically charged particles in space, near our planet, and snares them in an invisible, doughnut-shaped pen around Earth known as the ring current.

This captive swarm of charged particles plays an important role in how Earth reacts to changing conditions in space, called space weather, which can affect the technology we rely on, such as satellites and power grids. Yet there is still a lot we do not know about the ring current.

NASA is preparing to launch a mission designed to provide a unique, inside-out view of the ring current. Called STORIE (Storm Time O+ Ring current Imaging Evolution), it is scheduled to launch in May aboard the 34th SpaceX commercial resupply services mission to the International Space Station for NASA. The mission is flying as part of the Space Test Program – Houston 11 (STP-H11) payload, a partnership between the U.S. Space Force and NASA. Once it is robotically installed on the exterior of the space station (expected a few days after its arrival), STORIE will look outward at the ring current, helping scientists answer longstanding questions about how it grows and shrinks and what kind of particles it’s made of.

“These particles have important space weather impacts,” said Alex Glocer, STORIE’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where the instrument was designed and constructed. “We want to understand how that trapped population is built up, and where it comes from.”

These details are especially important during solar storms, when outbursts from the Sun can lead to magnetic disturbances at Earth. Similar to Earth’s Van Allen radiation belts but filled with lower-energy particles, the ring current tends to fluctuate in size, shape, and intensity more dramatically than the radiation belts do during solar storms. Plus, in the ring current, positively charged particles and negatively charged particles flow in opposite directions, creating electrical currents. So, changes there can lead to magnetic fluctuations and induced currents on the ground, potentially affecting pipelines and power lines. The ring current can also contribute to charge buildup on the surface of Earth-orbiting satellites, which can spark spacecraft glitches. Additionally, when energy ramps up in the ring current, some of that energy gets transferred to the upper atmosphere, making it heat up, puff out, and create more drag on satellites, which can cause the spacecraft to deorbit sooner than expected.

However, it’s difficult to study the ring current directly because the particles within it are invisible. “You can’t just image them with a camera,” Glocer explained.

Instead, STORIE will scan for the glow of energetic neutral atoms, or ENAs, that are formed when charged particles trapped in the ring current manage to escape. The particles earn their freedom by stealing an electron from Earth’s outer atmosphere, known as the exosphere, and become neutral. 

“Once those charged particles become neutral, they no longer feel the effects of Earth’s magnetic field, and they are no longer trapped,” Glocer said. “They can just fly off in any direction.”

By measuring the speed and direction of the ENAs, STORIE could help answer longstanding questions about the origins of particles in the ring current — whether they are supplied by a stream of particles flowing out from the Sun, known as the solar wind, or from Earth.

The STORIE team designed the instrument to pay special attention to positively charged oxygen atoms (O+) because, according to Glocer, “When you see oxygen, that comes from the atmosphere. You get very little of that from the solar wind.” If STORIE finds a lot of oxygen atoms, scientists will know the ring current is largely supplied by Earth’s atmosphere, rather than the solar wind.

Glocer and other scientists also want to find out whether the ring current’s population of charged particles build up in quick bursts or slowly and gradually. “Is it like filling a lake with the steady flow of a waterfall or a bunch of raindrops?” Glocer said.

Previous NASA missions — such as IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) and TWINS (Two Wide-angle Imaging Neutral-atom Spectrometers) — have looked at ring current ENAs before using a top-down view, which allowed them to see the whole ring current at once. However, from that perspective, ultraviolet light reflected by Earth — in the center of the ring — can interfere with the ENA observations, and the viewing geometry makes it hard to see trapped particles in the ring current near Earth’s equator.

“From STORIE’s inside-out perspective, you have Earth behind you, and you can see this trapped population near the equator that was hard for other missions to observe,” Glocer said.

Some sounding rocket experiments have gotten brief, inside-out views of the ring current in the past, but they only had a few minutes to observe and could only see a portion of the ring current during each flight. The view from STORIE will reveal one slice of the ring current at a time, but as the space station orbits Earth, STORIE will build up a complete picture of the ring current roughly every 90 minutes.

Over its six-month mission, STORIE will monitor how the ring current evolves over time and allow scientists to compare its behavior during solar storms versus when the Sun is quiet. Insights from STORIE will help us better understand how Earth responds to solar storms, improve space weather predictions, and help mitigate the effects of space weather on the technology humanity depends on.

Dive into NASA Research Through Citizen Science

NASA invites people of all ages and backgrounds to do NASA science as a part of real science projects that rely on volunteers. Citizen Science is a great way to make new friends, meet some scientists, and help NASA solve mysteries of the universe this summer – using just a phone or computer. You can join from anywhere, participate on your own schedule, and dive right into real research using actual mission data. Here are two examples:

• Through Space Cloud Watch, you can help NASA study noctilucent clouds. Noctilucent means “night-shining,” and that’s exactly what they do! During summer twilight at high latitudes, these clouds catch sunlight and appear to glow even in a darkened sky. Take a photo and submit a report to help scientists track how these rare clouds are changing.
• Take your cloud‑watching to another planet with Cloudspotting on Mars, where you review real NASA images to identify clouds above the Red Planet and help scientists understand Martian weather.

Curious about what other projects you might enjoy? See all current Citizen Science opportunities available through NASA’s Science Mission Directorate.
