Blue Origin's Giant Rocket Plans to Take Millions Into Space, But Should It?
"Our vision is millions of people living and working in space and New Glenn is a very important step," said Jeff Bezos, unveiling this week his space travel company Blue Origin's giant rocket named after Astronaut John Glenn.
Of course there is also billionaire entrepreneur extraordinaire Elon Musk's SpaceX, Richard Branson's Virgin Galactic and Paul Allen's Vulcan Aerospace. Dream big, that's the spirit! The final frontier with limitless possibilities. Our boys and their toys. Great fun!

Most of us sail at a lower orbit of course. Our games, our striving and exploration, our fun, takes place a little closer to Earth. My soul is nourished near and on the sea, so boats are my toys of choice. In my middle age, I have largely traded the competitive sailboat racing of my youth for a desire to "mess around" in relatively small, wooden boats in particular—sail and power—luxuriating in their handcrafted and poetic aesthetic.
As I've documented previously, large, ocean-going yachts are a whole different kettle of fish and pose a particularly grotesque challenge to any sense of a responsible carbon footprint, even if money is no object.
My "boat toy" desires are far more humble. Until a couple weeks ago, my "yachting" consisted of a high performance paddle board with a bamboo deck—sustainable right? In my future, I see a pretty day sailor, handcrafted in Maine out of local wood (I sold my prior sailboat since the kids preoccupied my free time) and a small motorboat to explore harbors (we call this "toodling around") and to make occasional short journeys around the southern New England coast where I live.
This summer, I visited the talented craftsman Doug Hylan and his partner Ellery Brown of Hylan & Associates in Brooklin, Maine to continue a conversation we've had on and off for over a year about building a small "green" powerboat. Same logic as a car or a house—energy, materials, etc. The challenge of making motorboats fuel-efficient is that it takes much more energy to push a boat through the water than to roll a car down a road. And a boat requires an exponential increment of power to push it faster than what's called "hull speed"—in other words to make it rise up and plane.

So the design challenge was to find the right shape (long, narrow and light), but stable enough for offshore conditions (wide and heavy is better) and with a highly efficient engine that would go "just fast enough." Doug has done some cutting edge work in this arena, with some updated versions of classic designs and power system innovations. But even with Doug's design ingenuity, latest technology and lightweight building techniques, he hasn't yet come up with a way to overcome those pesky laws of physics. Water is heavy and hydrostatic pressure is a bear.
As we were talking over the concept we had in mind, I sensed a distinct lack of enthusiasm for my vision of the first truly "green" picnic boat, locally crafted, that had the potential to redefine pleasure boating away from the unsustainable fiberglass that ends up on a junk heap and overwhelm Doug with new orders in the process. That's when he turned to me and said, "You know John, if you want to enjoy green, responsible boating, just slow down."
Doug's truth pierced Maine's stark summer beauty as we looked across the cove, silently absorbing the implications that ran far beyond boats. All the latest advances in design and technology couldn't come close to simply riding down the steeply sloped and physics determined energy curves he had showed me (slow down, use exponentially less energy).
I gave up on a new, high tech wooden boat and bought a classic bass boat that has been for sale all summer, built out of wood in 1969 and totally restored in 2009. For a fraction of what a new boat would cost I might add. Reuse, recycle!
And I'll be the guy going slow, at least most of the time. At hull speed (about 10 miles per hour), I'll burn less than a gallon of diesel per hour, a quarter of that when just calmly exploring a shoreline with friends in good conversation, going slow, enjoying the quiet. That's when the experience feeds the soul and relationships deepen, so it's not all sacrifice. Going "fast" when we "need to get somewhere" (about 22 miles per hour is tops in this case), I'll burn 8 gallons per hour with a guilty conscious.
In contrast, a yacht like I wrote about before will burn between 20 and 40 gallons per hour going 10 miles per hour. And a fast offshore fishing boat designed to get out to the shelf for the big fish and back in a day, burns 150 gallons per hour at the high speed necessary to be home for dinner—in other words, a 500 gallon a day toy.
My boat toy fetish makes me complicit, as does the rest of my lifestyle. But it's mostly the flying I do. As many have pointed out, we sustainability workers sure do fly around a lot. Flying kills a carbon budget fast. Physics again. No doubt we Americans have a big adjustment to make with our living. Much less flying and offshore fishing. More fly fishing. And more sailing, sailor. Not so bad.
Which brings us back to space travel. There certainly are real societal benefits from space exploration and some interesting space opportunities only these super-human entrepreneurs could ever dream up. But a little research suggests a frightening energy curve—based on those same pesky laws of physics—that we must confront (hopefully with Doug Hylan's wisdom hovering about).
Aside from the money issue, the amount of fuel for a one day (probably hour or less) zero gravity tourist experience in space you wonder? Well, according to my calculations based on one seemingly reliable source, it's 64,000 gallons of diesel equivalent.
Some fun. Sail on, Sail on, sailor.

Since even moderate-intensity workouts offer a slew of benefits, walking is a good choice for people looking to stay healthy.
How to Rock Your Walk<p>Walking isn't just fun and healthy. It's accessible.</p><p>"Walking is cheap," says Dr. John Paul H. Rue, a sports medicine doctor at <a href="https://mdmercy.com/" target="_blank">Mercy Medical Center in Baltimore</a>. "You can do it anywhere at any time; [it] requires little to no special equipment and has many of the same cardio benefits as running or other more intense workouts."</p><p>Want to up your walking game? Try the tips below.</p>
Use Hand Weights<p>Cardio and strength training can go hand-in-hand when you add weights to your walk.</p><p>A <a href="https://journals.lww.com/acsm-msse/Fulltext/2019/03000/Associations_of_Resistance_Exercise_with.14.aspx" target="_blank">2019 study</a> found that weight training is good for your heart, and <a href="https://www.mayoclinicproceedings.org/article/S0025-6196(17)30167-2/abstract" target="_blank">research</a> shows it reduces the risk of developing a <a href="https://www.healthline.com/health/nutrition-metabolism-disorders" target="_blank">metabolic disorder</a> by 17 percent. People with metabolic disorders have a higher chance of being diagnosed with high cholesterol, high blood pressure, and diabetes.</p><p>Rue suggests not carrying weights for your entire walk.</p><p>"Hand weights can give you an added level of energy burning, but you have to be careful with these because carrying [them] over a long period of time or while walking could actually lead to some overuse injuries," he says.</p>
Make It a Circuit<p>As another option, consider doing a circuit. First, put a pair of dumbbells on your lawn or somewhere in your home. Walk around the block once, then stop and do some bicep curls and tricep lifts before walking around the block again.</p><p>Rue recommends <a href="https://www.healthline.com/health/exercise-fitness/running-with-weights" target="_blank">avoiding ankle weights</a> during cardio workouts, as they force you to use your quadriceps rather than hamstrings. They can also cause muscle imbalance, according to the <a href="https://www.health.harvard.edu/staying-healthy/wearable-weights-how-they-can-help-or-hurt" target="_blank">Harvard Health Letter</a>.</p>
Find a Fitness Trail<p>Strength training isn't limited to weights. You can get stronger by <a href="https://www.healthline.com/health/bodyweight-workout" target="_blank">simply using your body</a>.</p><p>Often found at parks, fitness trails are obstacle courses with equipment for pullups, pushups, rowing, and stretches to build upper and lower body strength.</p><p>Try searching "fitness trails near me" online, checking out your local parks and recreation website, or calling the municipal office to <a href="https://calisthenics-parks.com/" target="_blank">find one</a>.</p>
Recruit a Friend<p>People who workout together stay healthy together.</p><p><a href="https://bmcgeriatr.biomedcentral.com/articles/10.1186/s12877-017-0584-3" target="_blank">One study</a> showed that older adults who exercised with a group improved or maintained their functional health and enjoyed their lives more.</p><p>Enlist the help of a walking buddy with a regimen you aspire to have. If you don't know anyone in your area, apps like <a href="https://www.strava.com/" target="_blank">Strava</a> have social networking features so you can get support from fellow exercisers.</p>
Try Meditation<p>According to the <a href="https://www.nccih.nih.gov/research/statistics/nhis/2017" target="_blank">2017 National Health Interview Survey</a>, published by the National Institutes of Health, meditation is on the rise, and for good reason.</p><p>Researchers <a href="https://pubmed.ncbi.nlm.nih.gov/29616846/" target="_blank">found</a> that mind-body relaxation practices can regulate inflammation, <a href="https://www.healthline.com/health/biological-rhythms" target="_blank">circadian rhythms</a>, and <a href="https://www.healthline.com/health/glucose" target="_blank">glucose</a> metabolism, as well as lower <a href="https://www.healthline.com/health/high-blood-pressure-hypertension" target="_blank">blood pressure</a>.</p><p>"Any form of exercise can be turned into a meditation of some type, either by the surroundings you are walking in, like a park or trail, or by blocking out the outside world with music on your headphones," Rue says.</p><p>You can also play a podcast or download an app like <a href="https://www.headspace.com/headspace-meditation-app" target="_blank">Headspace</a> that has a library of guided meditations to practice while you walk.</p>
Do Fartlek Walks<p>Typically used in running, fartlek intervals alternate periods of increased and decreased speed. These are <a href="https://www.healthline.com/nutrition/benefits-of-hiit" target="_blank">high-intensity interval training (HIIT)</a> workouts, which allow exercisers to accomplish more in less time.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154075" target="_blank">One study</a> showed that 10-minute interval training improved <a href="https://www.healthline.com/health/metabolic-syndrome" target="_blank">cardiometabolic</a> health, or lowered the risk of heart disease, stroke, and diabetes, just as well as working out at a continuous pace for 50 minutes.</p><p><a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0111489" target="_blank">Research</a> also shows that HIIT workouts increase muscle <a href="https://www.healthline.com/health/fast-twitch-muscles" target="_blank">oxidative</a> capacity, or the ability to use oxygen. To do a fartlek walk, try walking at an increased pace for 3 minutes, slow down for 2 minutes, and repeat.</p>
Gradually Increase Pace<p>A faster walking pace is associated with a lower risk of <a href="https://www.healthline.com/health/copd" target="_blank">chronic obstructive pulmonary disease (COPD)</a> and respiratory diseases, according to a <a href="https://pubmed.ncbi.nlm.nih.gov/30303933/" target="_blank">2019 study</a>.</p><p>Still, it's best not to go from a stroll to an Olympic-worthy power walk in a day. Instead, increase your pace gradually to prevent injury.</p><p>"Start by walking at a brisk pace for about 10 minutes per day, 3 to 5 days per week," Rue says. "Once you've done this for a few weeks, increase your time by 5 to 10 minutes per day until you get to 30 minutes."</p>
Add Stairs<p>You've likely heard that taking the stairs instead of an elevator is a way to add more movement into your daily routine. It's also a way to step up your walking. Stair climbing has been shown to <a href="https://www.sciencedirect.com/science/article/pii/S2211335519301123?via%3Dihub" target="_blank">decrease the risk of mortality</a> and can easily add a bit more challenge to your walk.</p><p>If you don't have stairs in your home, you can often find them outside a local municipal building, train station, or at a high school stadium.</p>
Is Your Walk a True Cardio Workout?<p>Not all walks are equal. A walk that's too leisurely may not provide enough burn to qualify as cardio. To see if you're getting a good workout, try to <a href="https://www.healthline.com/health/how-to-check-heart-rate" target="_blank">measure your heart rate</a> using a monitor.</p><p>"A target goal for a good walking workout heart rate is about 50 to 70 percent of your maximum heart rate," Rue says, adding that maximum heart rate is <a href="https://www.healthline.com/health/fitness-exercise/fat-burning-heart-rate" target="_blank">typically calculated</a> by 220 beats per minute minus your age.</p><p>You can also monitor how easily you can carry on a conversation while you walk to gauge your heart rate.</p><p>"If you can walk and carry on a normal conversation, that's probably a lower intensity walk," says Rue. "If you are slightly breathless but can still have a conversation, that's probably a moderate workout. If you are out of breath and can't talk normally, that's a vigorous workout."</p>
Takeaway<p>By shaking up your routine, you can add excitement to your workout and reap even more rewards than a basic walk provides. Increasing the pace and intensity of a workout will make it more effective.</p><p>Simply pick your favorite variation to add some spice to your next walk.</p>

Summer and fall are great seasons to enjoy the outdoors. But if you're already spending extra time outside because of the COVID-19 pandemic, you may be out of ideas on how to make fresh-air activities feel special. Here are a few suggestions to keep both adults and children entertained and educated in the months ahead, many of which can be done from the comfort of one's home or backyard.
The coronavirus may linger in the air in crowded indoor spaces, spreading from one person to the next, the World Health Organization acknowledged on Thursday, as The New York Times reported. The announcement came just days after 239 scientists wrote a letter urging the WHO to consider that the novel coronavirus is lingering in indoor spaces and infecting people, as EcoWatch reported.
