2 newly launched NASA missions will help scientists understand the influence of the Sun, both from up close and afar

Ryan French, University of Colorado Boulder

Even at a distance of 93 million miles (150 million kilometers) away, activity on the Sun can have adverse effects on technological systems on Earth. Solar flares – intense bursts of energy in the Sun’s atmosphere – and coronal mass ejections – eruptions of plasma from the Sun – can affect the communications, satellite navigation and power grid systems that keep society functioning.

On Sept. 24, 2025, NASA launched two new missions to study the influence of the Sun on the solar system, with further missions scheduled for 2026 and beyond.

I’m an astrophysicist who researches the Sun, which makes me a solar physicist. Solar physics is part of the wider field of heliophysics, which is the study of the Sun and its influence throughout the solar system.

The field investigates the conditions at a wide range of locations on and around the Sun, ranging from its interior, surface and atmosphere, and the constant stream of particles flowing from the Sun – called the the solar wind. It also investigates the interaction between the solar wind and the atmospheres and magnetic fields of planets.

The importance of space weather

Heliophysics intersects heavily with space weather, which is the influence of solar activity on humanity’s technological infrastructure.

In May 2024, scientists observed the strongest space weather event since 2003. Several Earth-directed coronal mass ejections erupted from the Sun, causing an extreme geomagnetic storm as they interacted with Earth’s magnetic field.

This event produced a beautiful light show of the aurora across the world, providing a view of the northern and southern lights to tens of millions of people at lower latitudes for the first time.

However, geomagnetic storms come with a darker side. The same event triggered overheating alarms in power grids around the world, and triggered a loss in satellite navigation that may have cost the U.S. agricultural industry half a billion dollars.

However, this is far from the worst space weather event on record, with stronger events in 1989 and 2003 knocking out power grids in Canada and Sweden.

But even those events were small compared with the largest space weather event in recorded history, which took place in September 1859. This event, considered the worst-case scenario for extreme space weather, was called the Carrington Event. The Carrington Event produced widespread aurora, visible even close to the equator, and caused disruption to telegraph machines.

If an event like the Carrington event occurred today, it could cause widespread power outages, losses of satellites, days of grounded flights and more. Because space weather can be so destructive to human infrastructure, scientists want to better understand these events.

NASA’s heliophysics missions

NASA has a vast suite of instruments in space that aim to better understand our heliosphere, the region of the solar system in which the Sun has significant influence. The most famous of these missions include the Parker Solar Probe, launched in 2018, the Solar Dynamics Observatory, launched in 2010, the Solar and Heliospheric Observatory, launched in 1995, and the Polarimeter to Unify the Corona and Heliosphere, launched on March 11, 2025.

The most recent additions to NASA’s collection of heliophysics missions launched on Sept. 24, 2025: Interstellar Mapping and Acceleration Probe, or IMAP, and the Carruthers Geocorona Observatory. Together, these instruments will collect data across a wide range of locations throughout the solar system.

IMAP is en route to a region in space called Lagrange Point 1. This is a location 1% closer to the Sun than Earth, where the balancing gravity of the Earth and Sun allow spacecraft to stay in a stable orbit.

IMAP contains 10 scientific instruments with varying science goals, ranging from measuring the solar wind in real time to improve forecasting of space weather that could arrive at Earth, to mapping the outer boundary between the heliosphere and interstellar space.

IMAP will study the solar wind from a region in space nearer to the Sun where spacecraft can stay in a stable orbit.

This latter goal is unique, something scientists have never attempted before. It will achieve this goal by measuring the origins of energetic neutral atoms, a type of uncharged particle. These particles are produced by plasma, a charged gas of electrons and protons, throughout the heliosphere. By tracking the origins of incoming energetic neutral atoms, IMAP will build a map of the heliosphere.

The Carruthers Geocorona Observatory is heading to the same Lagrange-1 orbit as IMAP, but with a very different science target. Instead of mapping all the way to the very edge of the heliosphere, the Carruthers Geocorona Observatory is observing a different target – Earth’s exosphere. The exosphere is the uppermost layer of Earth’s atmosphere, 375 miles (600 kilometers) above the ground. It borders outer space.

Specifically, the mission will observe ultraviolet light emitted by hydrogen within the exosphere, called the geocorona. The Carruthers Geocorona Observatory has two primary objectives. The first relates directly to space weather.

The observatory will measure how the exosphere – our atmosphere’s first line of defense from the Sun – changes during extreme space weather events. The second objective relates more to Earth sciences: The observatory will measure how water is transported from Earth’s surface up into the exosphere.

Looking forward

IMAP and the Carruthers Geocorona Observatory are two heliophysics missions researching very different parts of the heliosphere. In the coming years, future NASA missions will launch to measure the object at the center of heliophysics – the Sun.

In 2026, the Sun Coronal Ejection Tracker is planned to launch. It is a small satellite the size of a shoebox – called a CubeSat – with the aim to study how coronal mass ejections change as they travel through the Sun’s atmosphere.

In 2027, NASA plans to launch the much larger Multi-slit Solar Explorer to capture high-resolution measurements of the Sun’s corona using a state-of-the-art instrumentation. This mission will work to understand the origins of solar flares, coronal mass ejections and heating within the Sun’s atmosphere.

FAA Certifies Boeing 737-7: What It Means for Airlines and the 737 MAX Program

The FAA has certified Boeing’s new 737-7, clearing the smallest 737 MAX variant for service as Boeing and Southwest prepare for first deliveries.

Published

on

737 7 max ID fb3c1b364a1c

The U.S. Federal Aviation Administration has certified Boeing’s new 737-7, granting the company an amended type certificate that clears the smallest member of the 737 MAX family for commercial service. The milestone closes a multi-year certification effort and puts the focus on execution: Boeing and launch customer Southwest Airlines say preparations are underway to support first deliveries.

For STM Daily News readers, the headline isn’t just “another plane gets approved.” It’s a signal that Boeing has now cleared a key MAX variant designed for long-range flexibility in a smaller footprint—an aircraft type airlines can use to open or defend routes where demand is strong, but not strong enough to justify a larger narrowbody.

What FAA certification means

An amended type certificate means the FAA has approved the 737-7’s design as compliant with commercial aviation regulations. In practical terms, certification allows airlines to place the aircraft into revenue service once deliveries begin and operator-specific steps—training, manuals, maintenance programs, and entry-into-service planning—are completed.

Boeing also said the FAA updated Boeing Production Certificate No. 700 (PC 700) to include the 737-7, supporting production and delivery activities.

Why the 737-7 matters in the MAX lineup

Boeing positions the 737-7 as the smallest and longest-range member of the 737 MAX family. The company says it typically seats 135 to 160 passengers in a two-class configuration and offers a range of up to 3,800 nautical miles (7,040 km). That combination matters because it gives airlines more options to fly longer “thin” routes—markets where frequency and reach matter more than packing in additional seats.

Boeing also highlights performance for operations out of high-altitude airports and in hot climates, where takeoff performance and payload-range tradeoffs can shape fleet decisions.

Efficiency claims: fuel, emissions, and noise

Boeing says the 737-7, like other 737 MAX jets, reduces fuel use and CO2 emissions by 20% and cuts the noise footprint by 50% compared to the airplanes it typically replaces. For airlines, those improvements typically show up in two ways:

  • Route economics: lower fuel burn can improve margins on longer sectors and reduce exposure to fuel-price swings.
  • Operational constraints: quieter aircraft can help with airport noise requirements and community pressure, while lower emissions support sustainability targets.

Inside the certification effort

Boeing said the certification program began in 2018 and included more than 1,000 hours of flight and ground testing, extensive system safety analysis, and human factors reviews. The company also noted an updated engine anti-ice system to address a potential condition discovered during flight testing.

Boeing Commercial Airplanes President and CEO Stephanie Pope called the certification “important” validation of the airplane’s design and the work of the MAX development team. Mike Sinnett, senior vice president of Product Strategy, Product Development and Development Programs, said Boeing held regular discussions with the FAA and that the process has sharpened the company’s understanding of current regulatory requirements—knowledge Boeing expects will accelerate future development with a renewed emphasis on human factors, safety, and quality.

What to watch next

With certification complete, the next phase is about delivery timing and real-world deployment.

  1. First deliveries to Southwest: Boeing and Southwest are preparing for delivery of the first airplane, including updates to final configuration.
  2. Production stability: certification removes a major hurdle, but supply chain health and production cadence will determine how quickly the 737-7 shows up in airline schedules.
  3. The 737-10 timeline: Boeing reiterated it is working to certify the 737-10 this year, keeping attention on how quickly the final MAX variant clears regulatory review.

The bigger MAX picture

Boeing said the 737 MAX family order book stands at more than 7,200 airplanes, with more than 2,300 delivered through the end of June 2026. The 737-7’s certification adds another deliverable product to that portfolio—one aimed at airlines that want long range without stepping up to a larger gauge.

Bottom line

FAA certification of the 737-7 is a meaningful milestone for Boeing and for airlines looking for a smaller narrowbody with long-range capability. The real test now is operational: turning certification into on-time deliveries and reliable entry into service—while the industry watches Boeing’s push to certify the 737-10.

From Hand Signals to Smart Crosswalks: The Evolution of the Modern Pedestrian Signal

Discover the history of the modern pedestrian signal, from Garrett A. Morgan’s groundbreaking traffic signal to today’s smart, accessible crosswalks.

Published

on

Last Updated on July 12, 2026 by Daily News Staff

The Evolution of the Modern Pedestrian Signal

Every day, millions of people rely on pedestrian signals to cross busy street safely. A glowing white walking figure, an orange-red hand, and a countdown timer have become familiar sights around the world. While these signals may seem like simple pieces of infrastructure, they are the result of more than a century of innovation, engineering, and public safety improvements.

The modern pedestrian signal did not appear overnight. Instead, it evolved through the contributions of inventors, engineers, city planners, and transportation officials who continually refined traffic control systems as cities grew and automobiles became more common.

The Early Days of Traffic Control

Before electric traffic signals, intersections were controlled by police officers, railway-style semaphores, or even hand signals. As horse-drawn wagons gave way to automobiles in the early 1900s, traffic congestion and accidents increased dramatically, creating an urgent need for better traffic management.

One of the earliest electric traffic lights was installed in Cleveland, Ohio, in 1914. It used red and green lights and was manually operated. While it improved vehicle movement, pedestrians still had to judge for themselves when it was safe to cross.

How the Modern Pedestrian Signal Changed the Way We Cross Streets

Garrett A. Morgan’s Breakthrough

One of the most important milestones came in 1923 when inventor and entrepreneur Garrett Augustus Morgan received U.S. Patent No. 1,475,024 for an improved traffic signal.

Morgan’s design introduced a third position in addition to “Stop” and “Go.” This intermediate phase temporarily stopped traffic in every direction before allowing vehicles to proceed. The brief pause reduced confusion at intersections and provided additional time for pedestrians to cross safely.

Morgan reportedly developed his design after witnessing a serious traffic accident. His invention demonstrated how thoughtful engineering could improve public safety while making increasingly busy streets more efficient.

Although Morgan did not invent the illuminated “WALK” and “DON’T WALK” pedestrian signal used today, his three-position signal became a foundational step in the evolution of modern traffic control.

The Birth of Dedicated Pedestrian Signals

As cities expanded after World War II, pedestrian safety became an even greater concern. More people were walking in increasingly crowded downtown districts, and separating pedestrian movements from vehicle traffic became a priority.

During the early 1950s, several American cities began experimenting with dedicated pedestrian signals. New York City became one of the first major municipalities to install illuminated “WALK” and “DON’T WALK” signs at busy intersections.

These early systems gave pedestrians their own designated crossing phase, reducing conflicts with turning vehicles and improving safety at some of the nation’s busiest intersections.

Standardization Across America

By the 1960s and 1970s, traffic engineers recognized the importance of creating consistent traffic control devices nationwide.

The Manual on Uniform Traffic Control Devices (MUTCD) established national standards for traffic signs, pavement markings, and pedestrian signals. Standardized designs helped ensure that pedestrians could understand crossing signals regardless of where they traveled in the United States.

Eventually, words gave way to internationally recognized symbols—a walking person to indicate it was safe to cross and an upraised hand to indicate pedestrians should wait. These symbols transcended language barriers and improved accessibility for visitors and non-English speakers.

The Countdown Era

One of the most significant modern improvements arrived with pedestrian countdown timers.

Rather than simply flashing a warning, countdown displays show exactly how many seconds remain before the crossing phase ends. Research has shown that countdown timers help pedestrians make better crossing decisions and improve compliance with traffic signals.

Today, countdown timers have become standard equipment at intersections across much of the United States.

Accessibility Takes Center Stage

Modern pedestrian signals are designed to serve everyone.

Accessible Pedestrian Signals (APS) now provide audible tones, spoken messages, vibrating push buttons, and locator sounds that assist pedestrians who are blind or have low vision. These features allow more people to navigate intersections independently and safely.

The continued development of accessible technology reflects a broader commitment to making transportation systems inclusive for all users.

The Future of Pedestrian Safety

Pedestrian signals continue to evolve.

Many cities now use smart traffic systems that detect pedestrians waiting to cross, automatically adjust signal timing based on traffic conditions, and prioritize people walking during busy periods.

Researchers are exploring artificial intelligence, connected vehicle technology, and sensor-based systems capable of communicating directly with autonomous vehicles. Future pedestrian crossings may adapt in real time to weather conditions, crowd sizes, emergency vehicles, and even the needs of older adults or individuals with disabilities.

A Legacy Built by Many Innovators

The pedestrian signal we know today is the product of more than a century of collaboration and innovation.

Early traffic engineers created the first electric traffic lights. Garrett A. Morgan improved intersection safety with his groundbreaking three-position traffic signal. Transportation agencies standardized traffic control devices, while engineers continued refining pedestrian technology through countdown timers, accessible features, and intelligent traffic systems.

Every safe crossing today reflects the work of countless inventors, planners, researchers, and public officials dedicated to protecting lives.

As cities continue to grow and transportation technology advances, the humble pedestrian signal remains one of the most effective—and often overlooked—public safety innovations ever developed.

At STM Daily News, we celebrate the inventors, engineers, and visionaries whose everyday innovations quietly improve life for millions of people. Sometimes the most important inventions aren’t the ones that grab headlines—they’re the ones we depend on every single day without giving them a second thought.
