Bravo to NASA!

A Dream Takes Flight! Today, Our Ingenuity #MarsHelicopter Became The First Aircraft In History To Make

A dream takes flight! Today, our Ingenuity #MarsHelicopter became the first aircraft in history to make a powered, controlled flight on another planet.

In a video captured by our Perseverance Mars rover, the helicopter is shown hovering above the Red Planet's surface. During this first flight, the helicopter climbed to an altitude of 10 feet (3 meters), hovered, and then touched back down on the surface of Mars.

More images and video to come...

Join us at 2 p.m. ET (18:00 UTC) for an analysis of Ingenuity’s first flight and what's to come:

How Safe Are You From Covid When You Fly?

To understand how risky it may be to board a flight now, start with how air circulates in a plane.

image

More people are flying every day, as Covid restrictions ease and vaccinations accelerate. But dangerous variants have led to deadly new outbreaks, raising questions about just how safe it is to travel now.

In most single-aisle models, you are constantly breathing a mixture of fresh and recirculated air.

The high exchange rate on planes forces new and existing cabin air to mix evenly, with the goal of minimizing pockets of air that could become stale or linger for too long.

As more people fly — nearly 1.5 million people passed through U.S. airports on Friday — congestion and crowding in parts of the airport can make physical distancing a greater challenge.

Airports vary in size and passenger volume, configurations and on-location businesses, Harvard researchers found. That could increase the chances of exposure depending on where people linger and for how long.

Going to in-terminal restaurants, for example, can be risky because masks are routinely removed and kept off to eat.

The Harvard researchers found that many airports were not designed to mitigate the airborne spread of respiratory pathogens. Although some airports have installed new or additional filtration systems, distancing, vigilance and other safety practices are still crucial.

“The challenge isn’t just on a plane,” said Saskia Popescu, an epidemiologist specializing in infection prevention. “Consider the airport and the whole journey.”

Methodology

The particle air flow simulation was conducted using a later version Boeing 737NG as the model for the cabin interior, which only has side air inlets. The model accounted for passengers occupying all of the seats. A computational-fluid dynamics code system known as FEFLO was then used to simulate the flow of more than 2.5 million particles. A large number of very small particles were introduced at the cabin inflow ducts, in part to ascertain the movement of pathogens that may have passed through the HEPA filters without being caught. The simulation showed that the air close to passengers’ heads had been in the cabin for less than 50 seconds. The first 10 frames of the particle flow animation were slowed down for clarity.

Different positions of sneezes were simulated as part of the modeling, and only smaller particles were used to estimate what may become airborne. This assumed face coverings could block larger particles expelled during a sneeze that can otherwise land on surfaces and body parts. Particles in this visualization were scaled up for presentation purposes. Sources: Airbus; Boeing; Rainald Löhner, George Mason University, Center for Computational Fluid Dynamics. By Mika Gröndahl, Tariro Mzezewa, Or Fleisher and Jeremy White (The New York Times).

Yeah… let’s start with the smell of coffee

“If today gets difficult, remember the smell of coffee, the way sunlight bounces off a window, the sound of your favorite person’s laugh, the feeling when a song you love comes on, the color of the sky at dusk, and that we are here to take care of each other.”

— Chaplain Bob Keller, The Chaplain’s Corner (Washington46.org, May 7, 2020)

I want a house by each of these lakes…

Here it is folks:

My definitive ranking of my least favorite bodies of water! These are ranked from least to most scary (1/10 is okay, 10/10 gives me nightmares). I’m sorry this post is long, I have a lot of thoughts and feelings about this.

The Great Blue Hole, Belize

Here It Is Folks:

I’ve been here! I have snorkeled over this thing! It is terrifying! The water around the hole is so shallow you can’t even swim over the coral without bumping it, and then there’s a little slope down, and then it just fucking drops off into the abyss! When you’re over the hole the water temperature drops like 10 degrees and it’s midnight blue even when you’re right by the surface. Anyway. The Great Blue Hole is a massive underwater cave, and its roughly 410 feet deep. Overall, it’s a relatively safe area to swim. It’s a popular tourist attraction and recreational divers can even go down and explore some of the caves. People do die at the Blue Hole, but it is generally from a lack of diving experience rather than anything sinister going on down in the depths. My rating for this one is 1/10 because I’ve been here and although it’s kinda freaky it’s really not that bad.

Lake Baikal, Russia

Here It Is Folks:

When I want to give myself a scare I look at the depth diagram of this lake. It’s so deep because it’s not a regular lake, it’s a Rift Valley, A massive crack in the earth’s crust where the continental plates are pulling apart. It’s over 5,000 feet deep and contains one-fifth of all freshwater on Earth. Luckily, its not any more deadly than a normal lake. It just happens to be very, very, freakishly deep. My rating for this lake is a 2/10 because I really hate looking at the depth charts but just looking at the lake itself isn’t that scary.

Jacob’s Well, Texas

Here It Is Folks:

This “well” is actually the opening to an underwater cave system. It’s roughly 120 feet deep, surrounded by very shallow water. This area is safe to swim in, but diving into the well can be deadly. The cave system below has false exits and narrow passages, resulting in multiple divers getting trapped and dying. My rating is a 3/10, because although I hate seeing that drop into the abyss it’s a pretty safe place to swim as long as you don’t go down into the cave (which I sure as shit won’t).

The Devil’s Kettle, Minnesota

Here It Is Folks:

This is an area in the Brule River where half the river just disappears. It literally falls into a hole and is never seen again. Scientists have dropped in dye, ping pong balls, and other things to try and figure out where it goes, and the things they drop in never resurface. Rating is 4/10 because Sometimes I worry I’m going to fall into it.

Flathead Lake, Montana

Here It Is Folks:

Everyone has probably seen this picture accompanied by a description about how this lake is actually hundreds of feet deep but just looks shallow because the water is so clear. If that were the case, this would definitely rank higher, but that claim is mostly bull. Look at the shadow of the raft. If it were hundreds of feet deep, the shadow would look like a tiny speck. Flathead lake does get very deep, but the spot the picture was taken in is fairly shallow. You can’t see the bottom in the deep parts. However, having freakishly clear water means you can see exactly where the sandy bottom drops off into blackness, so this still ranks a 5/10.

The Lower Congo River, multiple countries

Here It Is Folks:

Most of the Congo is a pretty normal, if large, River. In the lower section of it, however, lurks a disturbing surprise: massive underwater canyons that plunge down to 720 feet. The fish that live down there resemble cave fish, having no color, no eyes, and special sensory organs to find their way in the dark. These canyons are so sheer that they create massive rapids, wild currents and vortexes that can very easily kill you if you fall in. A solid 6/10, would not go there.

Little Crater Lake, Oregon

Here It Is Folks:

On first glance this lake doesn’t look too scary. It ranks this high because I really don’t like the sheer drop off and how clear it is (because it shows you exactly how deep it goes). This lake is about 100 feet across and 45 feet deep, and I strongly feel that this is too deep for such a small lake. Also, the water is freezing, and if you fall into the lake your muscles will seize up and you’ll sink and drown. I don’t like that either. 7/10.

Grand Turk 7,000 ft drop off

Here It Is Folks:

No. 8/10. I hate it.

Gulf of Corryvreckan, Scotland

Here It Is Folks:

Due to a quirk in the sea floor, there is a permanent whirlpool here. This isn’t one of those things that looks scary but actually won’t hurt you, either. It absolutely will suck you down if you get too close. Scientists threw a mannequin with a depth gauge into it and when it was recovered the gauge showed it went down to over 600 feet. If you fall into this whirlpool you will die. 9/10 because this seems like something that should only be in movies.

The Bolton Strid, England

Here It Is Folks:

This looks like an adorable little creek in the English countryside but it’s not. Its really not. Statistically speaking, this is the most deadly body of water in the world. It has a 100% mortality rate. There is no recorded case of anyone falling into this river and coming out alive. This is because, a little ways upstream, this isn’t a cute little creek. It’s the River Wharfe, a river approximately 30 feet wide. This river is forced through a tiny crack in the earth, essentially turning it on its side. Now, instead of being 30 feet wide and 6 feet deep, it’s 6 feet wide and 30 feet deep (estimated, because no one actually knows how deep the Strid is). The currents are deadly fast. The banks are extremely undercut and the river has created caves, tunnels and holes for things (like bodies) to get trapped in. The innocent appearance of the Strid makes this place a death trap, because people assume it’s only knee-deep and step in to never be seen again. I hate this river. I have nightmares about it. I will never go to England just because I don’t want to be in the same country as this people-swallowing stream. 10/10, I live in constant fear of this place.

Honorable mention: The Quarry, Pennsylvania

I don’t know if that’s it’s actual name. This lake gets an honorable mention not because it’s particularly deep or dangerous, but it’s where I almost drowned during a scuba diving accident.
