NASA’s NEOWISE Mission: A Decade of Discovery and Defense in Space

Published

on

On August 8, 2024, a historic era in space exploration and planetary defense drew to a close as the NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) mission concluded its operations. Launched initially as WISE in December 2009, this mission was rechristened NEOWISE in 2013 when it took on a new life focused on identifying and characterizing asteroids and comets that skirt close to Earth’s orbital path.

Ending the NEOWISE Mission

The Final Shutdown

In a solemn yet celebratory event at the Earth Orbiting Missions Operation Center, located within NASA’s Jet Propulsion Laboratory in Southern California, engineers issued the final command to turn off NEOWISE’s transmitter. This last act was observed by mission members both past and present, along with top officials from NASA’s headquarters in Washington. Through NASA’s Tracking and Data Relay Satellite System, the command was dutifully relayed, officially decommissioning the spacecraft.

The Impact of Solar Activity

NASA pointed to the inevitable descent of NEOWISE in its orbit around the Earth, accelerated by increased solar activity, as a principal reason for the mission’s end. This solar activity heated the upper atmosphere, causing it to expand and exert additional drag on the spacecraft, which lacked its own propulsion system. Soon, NEOWISE will gracefully re-enter Earth’s atmosphere and disintegrate—a fiery finale to over a decade of monumental service.

A Legacy of Achievements

NEOWISE began its journey scanning the entire sky in infrared. This allowed for high sensitivity detection of celestial objects beyond the capability of previous surveys. Despite a running out of coolant in 2010, which was crucial for its infrared capabilities, NEOWISE transitioned to focusing on objects within our solar system that were naturally highlighted by the sun’s rays.

Under the stewardship of the Near-Earth Object Observations Program, NEOWISE excelled in its role. “The NEOWISE mission has been an extraordinary success story as it helped us better understand our place in the universe by tracking asteroids and comets that could be hazardous for us on Earth,” remarked Nicola Fox, Associate Administrator of the Science Mission Directorate at NASA Headquarters. Throughout its extensive operation, NEOWISE contributed significantly to our planetary defense knowledge, detecting over 3,000 near-Earth objects, some 215 of which were new discoveries, and identifying 25 new comets.

Paving the Way for NEO Surveyor

One of the most tangible legacies of NEOWISE is the groundwork it has laid for subsequent initiatives, notably the NEO Surveyor mission. Expected to launch no earlier than 2027, NEO Surveyor will continue the vital task of scanning the skies for potentially hazardous objects. This next-generation telescope will focus on detecting ‘dark’ asteroids and comets—objects that reflect little visible light and are difficult to track from Earth.

Amy Mainzer, principal investigator for both NEOWISE and NEO Surveyor, encapsulated the transition, stating, “While it is sad to see NEOWISE retire, it has set a robust foundation for the next steps in our planetary defense efforts.”

By all measures, the NEOWISE mission has been a beacon of scientific triumph and international cooperation. As the sun sets on this chapter of space exploration, the global community looks eagerly towards the advancements and discoveries that will follow in its path, safeguarding our planet and shedding light on the dark corners of our solar system.

Los Angeles is in a 4-year sprint to deliver a car-free 2028 Olympics

With the Olympic torch extinguished in Paris, all eyes are turning to Los Angeles for the 2028 Olympics.

The host city has promised that the next Summer Games will be “car-free.”

For people who know Los Angeles, this seems overly optimistic. The car remains king in LA, despite growing public transit options.

When LA hosted the Games in 1932, it had an extensive public transportation system, with buses and an extensive network of electric streetcars. Today, the trolleys are long gone; riders say city buses don’t come on schedule, and bus stops are dirty. What happened?

This question fascinates me because I am a business professor who studies why society abandons and then sometimes returns to certain technologies, such as vinyl records, landline phones and metal coins. The demise of electric streetcars in Los Angeles and attempts to bring them back today vividly demonstrate the costs and challenges of such revivals. https://www.youtube.com/embed/9X78ZqGyc5o?wmode=transparent&start=0 The 2028 Olympic Games will be held in existing sports venues around Los Angeles and are expected to host 15,000 athletes and over 1 million spectators.

Riding the Red and Yellow Cars

Transportation is a critical priority in any city, but especially so in Los Angeles, which has been a sprawling metropolis from the start.

In the early 1900s, railroad magnate Henry Huntington, who owned vast tracts of land around LA, started subdividing his holdings into small plots and building homes. In order to attract buyers, he also built a trolley system that whisked residents from outlying areas to jobs and shopping downtown.

By the 1930s, Los Angeles had a vibrant public transportation network, with over 1,000 miles of electric streetcar routes, operated by two companies: Pacific Electric Railway, with its “Red Cars,” and Los Angeles Railway, with its “Yellow Cars.”

The system wasn’t perfect by any means. Many people felt that streetcars were inconvenient and also unhealthy when they were jammed with riders. Moreover, streetcars were slow because they had to share the road with automobiles. As auto usage climbed and roads became congested, travel times increased.

Nonetheless, many Angelenos rode the streetcars – especially during World War II, when gasoline was rationed and automobile plants shifted to producing military vehicles. https://www.youtube.com/embed/AwKv3_WwD4o?wmode=transparent&start=0 In 1910, Los Angeles had a widely used local rail network, with over 1,200 miles (1,930 kilometers) of track. What happened?

Demise of public transit

The end of the war marked the end of the line for streetcars. The war effort had transformed oil, tire and car companies into behemoths, and these industries needed new buyers for goods from the massive factories they had built for military production. Civilians and returning soldiers were tired of rationing and war privations, and they wanted to spend money on goods such as cars.

After years of heavy usage during the war, Los Angeles’ streetcar system needed an expensive capital upgrade. But in the mid-1940s, most of the system was sold to a company called National City Lines, which was partly owned by the carmaker General Motors, the oil companies Standard Oil of California and Phillips Petroleum, and the Firestone tire company.

These powerful forces had no incentive to maintain or improve the old electric streetcar system. National City ripped up tracks and replaced the streetcars with buses that were built by General Motors, used Firestone tires and ran on gasoline.

There is a long-running academic debate over whether self-serving corporate interests purposely killed LA’s streetcar system. Some researchers argue that the system would have died on its own, like many other streetcar networks around the world.

The controversy even spilled over into pop culture in the 1988 movie “Who Framed Roger Rabbit,” which came down firmly on the conspiracy side.

What’s undisputed is that, starting in the mid-1940s, powerful social forces transformed Los Angeles so that commuters had only two choices: drive or take a public bus. As a result, LA became so choked with traffic that it often took hours to cross the city.

In 1990, the Los Angeles Times reported that people were putting refrigerators, desks and televisions in their cars to cope with getting stuck in horrendous traffic. A swath of movies, from “Falling Down” to “Clueless” to “La La Land,” have featured the next-level challenge of driving in LA.

Traffic was also a concern when LA hosted the 1984 Summer Games, but the Games went off smoothly. Organizers convinced over 1 million people to ride buses, and they got many trucks to drive during off-peak hours. The 2028 games, however, will have roughly 50% more athletes competing, which means thousands more coaches, family, friends and spectators. So simply dusting off plans from 40 years ago won’t work.

Olympic transportation plans

Today, Los Angeles is slowly rebuilding a more robust public transportation system. In addition to buses, it now has four light-rail lines – the new name for electric streetcars – and two subways. Many follow the same routes that electric trolleys once traveled. Rebuilding this network is costing the public billions, since the old system was completely dismantled.

Three key improvements are planned for the Olympics. First, LA’s airport terminals will be connected to the rail system. Second, the Los Angeles organizing committee is planning heavily on using buses to move people. It will do this by reassigning some lanes away from cars and making them available for 3,000 more buses, which will be borrowed from other locales.

Finally, there are plans to permanently increase bicycle lanes around the city. However, one major initiative, a bike path along the Los Angeles River, is still under an environmental review that may not be completed by 2028.

Car-free for 17 days

I expect that organizers will pull off a car-free Olympics, simply by making driving and parking conditions so awful during the Games that people are forced to take public transportation to sports venues around the city. After the Games end, however, most of LA is likely to quickly revert to its car-centric ways.

As Casey Wasserman, chair of the LA 2028 organizing committee, recently put it: “The unique thing about Olympic Games is for 17 days you can fix a lot of problems when you can set the rules – for traffic, for fans, for commerce – than you do on a normal day in Los Angeles.”

This article has been updated to indicate that Los Angeles has four light-rail lines.

Last Updated on March 7, 2026 by Daily News Staff

International Women’s Day is a global celebration that honors the achievements of women and highlights the progress still to be made in the fight for gender equality. On this day, people around the world come together to recognize the amazing contributions of women everywhere and to rally for greater gender equity in all areas of life.

#EmbraceEquity


The origins of International Women’s Day can be traced back to 1908, when 15,000 women marched through the streets of New York City to demand better working conditions and the right to vote. Since then, the celebration has grown to be an international event, with more than 100 countries recognizing the day. The United Nations even declared March 8th as International Women’s Day in 1975, to honor the struggles of women around the world.

This year’s International Women’s Day theme is #ChooseToChallenge, meaning that everyone is encouraged to call out gender bias and inequality when they see it. We’re also encouraged to celebrate women’s achievements, support each other, and take action for equality.

It’s important to recognize the progress we’ve made in terms of gender equality, but we still have a long way to go. International Women’s Day serves as a reminder that we must continue to fight for gender equality in all areas of life. Let’s use this day to honor the contributions of women around the world, and to continue the fight for a more equitable world.

Byron Allen’s Starz Stake Signals Bigger Moves in the Streaming Industry

Byron Allen’s Starz: Byron Allen has acquired a 10.7% stake in Starz Entertainment for approximately $25 million, signaling his long-term media strategy amidst industry consolidation. This investment positions him influentially in the evolving streaming market despite intense competition.

Byron Allen’s Starz investment

Media entrepreneur Byron Allen has taken another step toward expanding his growing media empire. Through his family office, Allen recently acquired a 10.7% stake in Starz Entertainment, purchasing the shares from a fund managed by former U.S. Treasury Secretary Steven Mnuchin.

The transaction, valued at approximately $25 million, gives Allen a significant minority position in the premium cable and streaming platform. While the investment itself may seem modest compared to the billion-dollar deals common in Hollywood, analysts say the move could signal a larger strategy unfolding in the rapidly evolving streaming industry.

Why the Starz Deal Matters

The shares were sold by Mnuchin’s Liberty 77 Capital fund, which previously invested in the company when Starz was still connected to its former parent, Lionsgate.

In 2025, Lionsgate completed a corporate restructuring that separated its operations into two distinct companies:

  • Lionsgate Studios – responsible for film and television production
  • Starz – focused on premium cable and streaming services

Following the spin-off, Starz became an independent publicly traded company. As a result, investors are still determining the platform’s long-term value in an increasingly crowded streaming marketplace.

A Streaming Platform With Loyal Audiences

Despite facing intense competition from larger platforms such as Netflix, Disney+, and Amazon Prime Video, Starz continues to maintain a strong subscriber base and recognizable content franchises.

  • Outlander – historical drama series
  • The Power franchise created by Courtney A. Kemp and executive produced by 50 Cent

Byron Allen’s Long-Term Media Strategy

Allen’s investment strategy has long focused on owning media distribution and infrastructure rather than simply producing content.

  • The Weather Channel
  • Dozens of local television stations across the United States
  • Multiple niche cable networks and digital platforms

Over the past several years, Allen has also pursued larger acquisitions, reportedly exploring deals involving companies such as Paramount Global and BET Media Group. While those deals did not materialize, they signaled his ambition to expand Allen Media Group into a major force in global media ownership.

The Bigger Picture: Industry Consolidation

Allen’s investment arrives during a time of significant disruption in the entertainment business. Traditional cable television continues to decline as audiences migrate toward streaming platforms. At the same time, major studios and media companies are struggling to make streaming services consistently profitable.

Industry observers believe these pressures could lead to a new wave of consolidation across Hollywood and the streaming sector. Smaller platforms like Starz could become attractive acquisition targets for larger companies seeking additional subscribers and content libraries.

A Potential Hidden Opportunity

For now, Allen’s 10.7% stake does not give him control of Starz. However, it does provide influence as one of the company’s larger shareholders and leaves open the possibility of increasing his ownership in the future.

If consolidation accelerates and streaming platforms begin merging or forming partnerships, assets like Starz could become significantly more valuable. For Byron Allen—whose career began as a stand-up comedian before evolving into one of the most prominent independent media owners in America—the investment may represent another calculated step in a decades-long strategy built around media ownership and long-term growth.
