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

National Recycling Day: Easy, Fun and Good for the Environment
How to make every day recycling day
(Family Features) With so many mixed messages, recycling can feel confusing, but the truth is simpler than you might think. Recycling isn’t just for today – it’s a year-round commitment to a healthier planet.
In honor of National Recycling Day, consider these facts about recycling from the experts and tips to make a difference.
Recycling Is Real
Americans recycle more than 6 billion pounds of plastic every year. Among the plastics recycled, polyethylene terephthalate (PET) remains a responsible material choice. PET is the world’s most recycled plastic, with more than 1.8 billion pounds of PET bottles and containers recovered in the U.S. annually. Since PET bottles can be made from 100% post-consumer recycled content, each recycled bottle contributes to a circular economy where materials are continuously reused instead of wasted.
Recycling PET Plastic is Better for the Environment
Countless others from academics, researchers and industry experts show plastics, such as PET specifically, often have a lower environmental impact. In fact, glass bottles produce three times the greenhouse gas emissions compared to PET bottles, and making an aluminum can produces twice the emissions, according to Life Cycle Assessment studies. Producing PET also uses less energy and water and lowers acid rain and smog potential. Using and recycling PET is a more responsible, more eco-friendly choice than banning plastic outright.
Recycling Saves Energy
Recycling PET bottles requires less energy than producing new glass bottles or aluminum cans. Every PET bottle you recycle helps conserve resources and supports a more responsible production cycle.
Not All Plastics are Created Equal
PET is a superstar among plastics because it can be recycled repeatedly without losing strength or quality. It’s also an inexpensive, lightweight and shatter-resistant package that preserves and protects the food and medicine people place in their bodies.
Recycling Can be Easy
Recycling services can be accessible, with many communities across the U.S. offering easy ways to recycle. Today more than 73% of all U.S. households have access to recycling, according to The Recycling Partnership.
By staying informed, choosing packaging that’s easily recyclable and recycling consistently, you can help build a more sustainable future every day. Visit recyclecheck.org to find out where you can recycle in your community.
5 Recycling Tips
- Know your plastics. Look for the No. 1 recycling symbol – inside three arrows forming a triangular shape – to identify polyethylene terephthalate (PET), helping ensure your recycling efforts are impactful.
- Recycle PET plastic packaging over bans. Choose products packaged in PET bottles where possible, as recycling PET reduces reliance on resource-heavy materials and greenhouse gas emissions.
- See recycling as energy conservation. PET bottle recycling uses significantly less energy compared to producing new glass bottles or aluminum cans.
- Think of recycling as an investment. Every PET container you recycle contributes to a circular economy and more sustainable world.
- Get involved within your community. Connect with local recycling programs and stay updated on your area’s recycling guidelines by visiting recyclecheck.org.
