If your kid came up to you and said he ran his bike into the neighbor’s garage door and made a dent, your reaction probably wouldn’t be congratulating him or her. Aside from checking to see if your kid is okay and not bug-eyed from a concussion, you would probably be a bit upset about the damage you’re going to have to pay for. However, for the kids at NASA, everyone is having a party.
In September, NASA completed its latest project of purposefully slamming a projectile into an asteroid for the sole purpose of being destructive – for a good reason. If you remember back in the days of your high school physics class, there were lessons about speed and mass. When two objects traveling at different speeds collide, energy gets transferred. The hope of the NASA project is to release enough energy colliding into it artificially that the asteroid’s path will be altered. As if out of a movie script, the project is basically a very expensive research experiment to see if it’s possible to change the path of an asteroid so it won’t hit Earth.
Now, there’s a lot to unravel here. Asteroids don’t just come out of nowhere, even though that seems the case. They fly around what we know as the Solar System in an orbit. That orbit goes around our sun. Depending on how the asteroid was brought in by the Sun’s gravity, that orbit either comes near or far from Earth. It also depends on our planet’s own orbit and where we are at the time. Crunch all this out with a lot of math, physics and timing, and you get probabilities of what are called close orbits or near misses.
Figuring out asteroid paths these days is serious business. It’s clear from geological and archaeological records that asteroids a few feet to dozens of feet in diameter can create cataclysmic damage if they hit the Earth at the right angle. Many glance off our atmosphere, but some have hit. And they leave very big craters; one hit the Yucatan millions of years ago and carved out a crater the size of a quarter of Central America.
So, back to the NASA project, bumping into an asteroid has made enough sense to actually try and see if it works. This is a risky business. One has to not just calculate the possibilities but, when they do occur, what does it mean for ramifications? Bumping an asteroid’s path a few dozen feet might not mean much now, or for a few years, but does it have a negative ripple effect a couple hundred years in the future? Who knows? At this point, it’s now happening. We collided our space bike with the asteroid and bumped it. Scientists at NASA and other research centers will spend the next ten or twenty years studying if there was an effect at all. And maybe it might be a good thing if nothing happened at all.
California’s Bold Project to Remove Iron Gate Dam
In the heart of California, a monumental endeavor is underway—one that promises to breathe new life into the environment and revitalize the natural world. The ambitious project centers around the removal of the colossal Iron Gate Dam, a massive structure that has obstructed the Klamath River for decades. As this dam is dismantled, nature is poised to make a triumphant comeback, and a vision of rewilding the region is set in motion.
A Glimpse into the History of Iron Gate Dam
The Iron Gate Dam, standing as a formidable barrier on the Klamath River, has a long history dating back to its construction in the early 1960s. The primary purpose of the dam was to generate hydroelectric power and to manage water resources for agricultural and industrial purposes. While the dam served these needs, it also brought about unintended consequences for the surrounding ecosystem.
Over the years, the dam has hindered the natural flow of the Klamath River, disrupting the intricate balance of the ecosystem and impeding the migration of fish, particularly salmon and steelhead. This disruption has had far-reaching effects, causing declines in fish populations and impacting the livelihoods of indigenous communities that rely on the river for sustenance and cultural significance.
A Vision for Restoration and Rewilding
Mark Bransom, the CEO of the Klamath River Renewal Corporation, is at the helm of this ambitious project to remove the Iron Gate Dam. He envisions a future where the Klamath River flows freely once more, unencumbered by the dam’s infrastructure. But it doesn’t stop there. Bransom and his team have elaborate plans to help nature reclaim the area that has long been stifled.
“As soon as the reservoir is drained, we’ll get out on the footprint there and begin some initial restoration activity,” Bransom explained. “We want to stabilize the remaining sediments using native vegetation.”
The concept of rewilding lies at the heart of this vision. Rewilding is a holistic approach to ecosystem restoration that aims to reintroduce native species, rebuild habitats, and allow natural processes to thrive. It’s about creating environments where nature can flourish independently, fostering a healthier and more sustainable ecosystem.
“One of the fastest ways to heal a river is to remove a dam,” says Ann Willis, the California regional director for American Rivers, a nonprofit dedicated to protecting clean water. “The good news is, when you have the opportunity to unjam a river, the river can start to restore itself almost from the moment that the water starts flowing again.”
As the Iron Gate Dam is gradually dismantled, it signifies not only the removal of concrete and steel but also a renewed hope for nature’s resilience. This ambitious project underscores the power of human actions to correct past mistakes and to foster a brighter future where nature can thrive once more.

No Mow May: The Benefits of Letting Your Garden Grow Wild
As the weather begins to warm up and spring blooms burst forth in gardens across the country, many gardeners are embracing a new movement: No Mow May. This initiative encourages homeowners to avoid mowing their lawns for the entire month of May and instead let the grass and wildflowers grow wild. While it may seem counterintuitive to let your lawn get out of control, there are many benefits to participating in No Mow May.
First and foremost, letting your grass grow wild can help support local ecosystems. Lawns that are frequently mowed are often monocultures, meaning they are dominated by a single type of plant, usually a specific species of grass. This can make it difficult for pollinators like bees and butterflies to find the nectar and pollen they need to survive. When you let your grass grow wild, it creates a diverse habitat for insects and other small animals. Wildflowers and other flowering plants provide food and shelter for bees, butterflies, and other pollinators, which in turn helps to support a healthy ecosystem.
In addition to supporting local ecosystems, No Mow May can also help to reduce your carbon footprint. Lawn mowers, whether electric or gas-powered, contribute to greenhouse gas emissions, which contribute to climate change. By skipping your weekly mow, you can reduce your carbon footprint and help to protect the environment.
But No Mow May isn’t just good for the environment—it can also be good for your wallet. By skipping the mow for a month, you can save on gas or electricity costs associated with running your lawn mower. Additionally, because you’re allowing your grass to grow longer, you won’t need to water it as frequently, which can save you money on your water bill.
Finally, No Mow May can be a fun and low-stress way to enjoy your garden. Instead of worrying about keeping your lawn perfectly manicured, you can sit back and enjoy the natural beauty of the wildflowers and grasses that grow in your yard. This can be a great way to connect with nature and take a break from the stresses of daily life.
Of course, there are some downsides to No Mow May. Allowing your grass to grow longer can make it more difficult to play outdoor games like soccer or frisbee. Additionally, some homeowners associations or municipalities may have rules or regulations regarding lawn maintenance, so it’s important to check with local authorities before participating in No Mow May.
