NASA Images from the 1960s

/

I did a lot of my growing up in the 1960s; the US space program had an impact on my education and perspective of the world so when I found 3 books of images from NASA in the 1960s available on Internet Archive for easy browsing- I savored the memories of seeing some of those images in newspapers and magazines shortly after they were taken. The images looking back at Earth from space were so different than the previously available aerial photographs taken from planes or balloons. Now we take for granted the satellite imagery in our everyday lives (for example, Google Maps satellite view). The NASA programs in the 1960s were steps along the technological path. A lot has happened in the past 50 years!

What a decade of Curiosity has taught us about Mars – Looking for signs of life.

Zion National Park, Utah – A view of the park from the International Space Station. A piece of trivia from the post: Cyanobacterial blooms are a threat to hikers and wildlife – exacerbated by intense summer heat.

Air pollution, including during wildfires, shows ill effects in children -So many questions popped into my mind as I read this article: Does keeping children indoors with modern air conditioning/heating filtered air help? Further air purification required? The children in the study were 9-11 years old; are some of the markers also indicators of stress they may have developed knowing there were wildfires?

Ultra high-speed photography captures hidden human figures in moving water – Eye candy

Heat pumps prove themselves during a harsh Maine Winter – Modern heat pumps do the job even at -21 degrees in Maine!

Neolithic Watermelons may have been valued for their seeds – Snacks! And now most watermelons we buy in stores doen’t have seeds at all!

Nahuku Lava Tube in Hawai’i Volcanoes National Park Closed to study its stability – Also known as Thurston Lava Tube. I walked through it when we were in Hawaii several years ago.

Vitamin K prevents cell death: New function for a long-known molecule – Important for blood clotting….but new research shows it is also a potent antioxidant that ameliorates cellular iron’s role in cell death (ferroptosis). There will probably be a lot of subsequent research following up this finding.

The science of making cheese – Infographic that shows the 4 steps: acidification, coagulation, reducing moisture content, and maturation.

The mysterious inner life of the octopus – Interesting article….or just look at the pictures!

Amazing Photo of Wisteria Trees Looks Like a Fireworks Display – Pictures from Japan’s Ashikaga Flower Park.

New Mexico Wildfire Spawns Fire Cloud – A pyrocumulonimbus cloud formed; the vertical plume reached the tropopause….an altitude of about 12 kilometers.

Heatwaves are altering our everyday lives – The new normal but we aren’t very well prepared for it; there are some obvious adaptations that are needed – particularly to electrical networks. No one wants infrastructure to fail at a critical time.

Well-preserved iron age arrow discovered in Norway – The arrow was recovered from a glacier…iron arrowhead, sinew, tar, thread, shaft, and feather fletching was preserved. It is about 30 inches long.

Rigid waterproof coating for paper aims to reduce our dependence on plastic – Interesting…would be great if it could speed the transition away from plastic for food packaging particularly. The article said the chemicals break down over time into harmless components…but didn’t say how long that took.

Chemicals that linger for decades in your blood – So many chemicals introduced in my lifetime are probably still in my blood. I can remember the spraying of DDT for mosquitoes in the ‘60s….one instance particularly of the straying truck going down the farm road near my grandparents house as we played in the back yard. How much of my exposure do I still have…did I pass along to my daughter?

Ultraviolet light reveals radiant hidden beauty of flowers – A project during the COVID-19 pandemic…beautiful results.

Archaeologists Unearth 3,000-Year-Old Giant Statues in Sardinian Necropolis – Over 7 foot tall…with almost emotionless expression, blocky nose and deep-set eyes. The two found most recently were boxers but about two dozen others have been found since the mid-1970s: 16 boxers, 4 archers, and 5 warriors.

Top 25 birds of the week: May 2022! – Bird appreciation….a source of beauty in the world.

Disparities in natural gas leak prevalence in US urban areas – Why can’t pipeline companies do better…not wait around until regulation requires them to do it? We should be more critical of the companies that they are not actively reducing leaks in their pipelines.

8 Fall Nature Experiences to Enjoy – There are so many things to enjoy in the outdoors during the fall – as the heat of summer fades away.

Exploring The Parks: 10 Historic Sites To Visit This Fall – More ideas for fall activities. I’ve been to all the sites they list that are on the east coast…but not necessarily in the fall.

NASA and USGS Launch Landsat 9 – The first Landsat was launched in July 1972 – the year my husband and I graduated from high school.

A new solid-state battery surprises the researchers who created it – Solid state electrolyte and an all-silicon anode – faster charge rates at room to low temperatures. There is a lot of battery research going on now …coming up with batteries that will help achieve the grid storage and transportation needs of the future.

Young People Are Anxious About Climate Change And Say Governments Are Failing Them – It’s not just young people that have this anxiety. Everyone I know has climate change anxiety….and say governments are failing us all.

Wind energy can deliver vital slash to global warming – It’s a component of the technology we need….it can’t solve everything alone but we have it ready to deploy now – and should just do it as quickly as we can. And it’s cheaper than using fossil fuels!

Coastal Northeastern US is a global warming hotspot; 2 degrees Celsius of summer warming has already occurred – From Maine to Delaware…the area is warming faster because of climate change linked alterations in the ocean and atmospheric conditions of the North Atlantic.

2021 Nature Conservancy Photo Contest Winners Highlight Global Wildlife and Nature – Beautiful…and thought provoking. My favorite was the artsy one at the end…a high key image.

Paradigm shift in treatment of type 2 diabetes to focus on weight loss – There are probably other chronic ‘diseases’ that have become more prevalent over the past few decades that could be improved with weight loss….but it is hard to lose weight…and keep it off. It requires permanent lifestyle changes.

Top 25 Birds of the week: Habitats! – Birds are everywhere (at least now/recent past). The decline in insect populations could make it problematic for many species to survive.

The Institutions of Extraterrestrial Liberty (Day 1: https://tinyurl.com/4t7zjv72 Day 2: https://tinyurl.com/2f9n4b72 Day 3: https://tinyurl.com/48rbba2k Day 4: https://tinyurl.com/5bbey7pr) – A series of webinars chaired by Charles Cockell (I enjoyed his astrobiology course on Coursera back in 2015 and his “Life in the Universe Pandemic Series’ back in Spring 2020). The subject in these webinars is freedom beyond Earth with talks on everything from liberty in Martian settlements to war in space. This is not about the search for life beyond Earth, but it is about the human future beyond Earth and how human societies might evolve over time. The schedule for each of the days is in the comments section so it is easy to select segments easily.

Gigantic flying pterosaurs had spoked vertebrae to support their 'ridiculously long' necks -- ScienceDaily – Their necks were longer than a giraffe’s…and the vertebrae had internal structure not seen in any other animal. The discovery was made with a CT scan and petrographic sections through the bone.  

Linking Birds, Farmer Attitudes and Conservation – The approach is not as straightforward as it might seem…there are nuances and feedback loops that need to be considered to get a positive result.

A breathtaking treasure reveals the power of the woman buried with it : Research Highlights – Early Bronze Age southeastern Spain…heavy silver diadem, silver ornaments…pots with intricate silver plating and daggers with silver-plated handles.

This white paint keeps surfaces cooler than surroundings, even under direct sunlight -- ScienceDaily – I remember being at White Sands National Park on a hot day and walking on the sand barefoot (i.e. the sand was not hot!). Hopefully the architectural norms will begin to shift toward white roofs and then durable paints/shingles will be readily available to make it affordable. The heat islands of cities would be reduced…which could be helpful now and an increasing benefit as climate change continues.

Nature Nerd Trivia: Wild Canids – Dog relatives from around the world.

Unique Activities for Yesterday:

Firsts for the season at our deck. We saw our first Dark-eye Junco for the season. A small flock has spent the winter in our area – frequently visiting our feeder – for many years. We think they go to the Appalachians/Alleghenies for the rest of the year rather than the far north.

2020 10 IMG_2644.jpg

I finally managed to get a picture of a Red-breasted Nuthatch enjoying the seed spilled under our feeder. There were other times recently that I thought I saw one but was never fast enough with my camera.

Hawai’i Island Festival of Birds Swag pack arrived. It took more than 10 days for the small envelope to get from Hawai’i to Maryland. I don’t know for sure how long it took because there was no postmark. I will use the field notebook (upper left, a nice fit for one of my photo vest pockets) and the magnet (lower right) is already on our refrigerator to remind us of the virtual festival…and we’ll sign up to go to the festival when it is held ‘in person’!

Filling a Day of Social Distance – 4/21/2020 - Macro Fabrics

/

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Looking at Life Magazine for May 1944 – I found some early work of Chesley Bonestell that launched his space art career…mixed in with the coverage of World War II.

Finished reading Bruntsfield Brook by Charles Cockell. I bought the Kindle version after hearing about it in one of the Life in the Universe Pandemic Series videos. It was a fun way to learn about microbial mats…wound into a story with lots of drama impacting the different kinds of microbes: phages, ice, pollution, and drought.

Links to my previous “filling a day of social distance” posts  here.

And now for a little project prompted by learning (from Charles Cockell in his Life in the Universe Pandemic Series) that Antonie van Leeuvenhoek first used macro lenses to assess the quality of fabric…then turned the lenses onto other things and became known as ‘the father of microbiology.’ For some reason I had never thought about what prompted him to be using glass lenses originally. So – I did a little project to look at different fabrics with the jeweler’s loupe…taking pictures with my phone through the loupe.

I started with the upholstery fabric on a couch. The colors are more vivid when they are magnified! I don’t know what the fiber content is…but it’s shiny…. that probably means it’s synthetic.

Clothes that I had that were labelled 100% cotton were all tops. 2 t-shirts (normal weight and thin) and a waffle shirt

I also had an older 100% cotton denim shirt. It is old enough to have some worn areas.

Then there were the cotton and polyester blends. The bandana didn’t have a label, but I lumped it with the blends because it was shiny. A pair of jeans and a t-shirt looked like cotton so I assume that the polyester part might be wrapped in cotton.

A quilted jacked had a looser weave and was shiny. A man’s shirt and my photovest were both a tight weave cotton/polyester.

I have a linen-look button front tunic that I have enjoyed wearing for years. I didn’t realize it was 100% polyester until I looked at the label. And it looks very much like plastic when magnified! I’d never thought of it as ‘shiny’ before.

20200419_135659.jpg

I had two silk scarves which I included in my pile to photograph.

And then there was acrylic blended with polyester (for a cardigan), with cotton (for a ribbed turtleneck) and nylon for a lightweight unlined sweater jacket. The last one looks like the 100% polyester tunic – although the fiber in the tunic is woven and the sweater jacket is a knit.

Overall – it was an interesting project. I am always keen to apply what I am learning, and this project blended the astrobiology lectures and the Fashion as Design class!

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Finishing Vermont Life issues. I finally browsed through the last of the Vermont Life issues. The magazine was published from 1946-2018 and most of the issues are available on Internet Archive. I started at the beginning back in July and just finished the last one (from summer 2018) yesterday. Every issue contains great photography…of beautiful places. It’s a great armchair travel to a place…and through time. I had a friend that had family in Vermont when I was growing up in Texas; she visited there almost every summer. I found myself looking at the pictures from the 1960s and realizing that she probably saw some of those places. I remember her talking about picking blueberries.

20200327_155856.jpg

IDing a plant for my sister. She sent me a picture from her Texas yard. I found a reference from Texas Master Naturalists easily enough – and passed along the id: Southern Dewberry (p. 23 of the reference).

Cleaning the filter on the air purifier. We’ve been running the air purifier more in our bedroom to keep the pollen allergies at bay – at least while we sleep. The red light came on to tell use the filter needed to be cleaned….it was an easy job…but we were without it for a couple of nights while everything dried. My husband and I both noticed the difference when we began running it again yesterday afternoon.

2020 04 IMG_8882 (3).jpg

Hearing the wind sweeping through the forest. Yesterday afternoon was very gusty – not stormy…it was a mostly sunny day. The wind came roaring through the forest ripping off small pieces of leaves and bud coverings from the tulip poplars; some of the bits ended up in our gutters.

The red maple is full of seeds – looking golden from afar but reds/greens show when looking closer; the seeds are mostly staying put; they are not ready to helicopter away from the tree.

How to avoid touching your face so much - BBC Future – Something we are all trying to learn to do along with making masks for whenever we venture away from the house.

A more balanced protein intake can reduce age-related muscle loss -- ScienceDaily – My take away -older people (me included) need to have a high quality protein at lunch…not leave it for the evening meal!

Bald Eagles and the Unfortunate Power of Forgetting – When I was growing up, bald eagles were rare. They are not now because people took action and stuck with it. Remembering will keep Bald Eagles around and maybe provide a blueprint for the way we all move forward to a healthier Earth.

Scientists find Earth and moon not identical oxygen twins -- ScienceDaily – The finding may challenge the current understanding of the formation of our Moon…..future modeling will need to explore that possibility. Previously models have tried to account for complete oxygen isotope homogenization between the Earth and Moon.

How to escape the tyranny of the clock - BBC Future – Now that I am retired…the tyranny of the clock is not as overwhelming as it was during my career. Right now – there is even less requirement for me to do anything at a particular time….maybe a Zoom meeting or when my shopper is collecting my groceries. Otherwise I set my own time. Text messages or telephone calls or my husband wanting to talk/assistance with a project are interruptions that are easily handled with whatever I am doing. It’s an easy time to enjoy a loosening of the tyranny of the clock.

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

  • Picking earrings to wear that I haven’t worn in a long time. Yesterday I wore some from Orlando FL and today they are from Watkins Glen NY. Earrings are my favorite item to purchase when I travel…small keepsakes that I can wear! Both are over 10 years old, but I still remember where I got them.

  • Maintaining the compost pile and walking around the yard. I’m trying to get out of the house at least once a day….enjoy that it is springtime here!

  • Watching the second installment of the Cincinnati Zoo’s Home Safari (about Rico the Porcupine). They have established a website where all the videos will be available after they air live. I am watching the recorded version, so I don’t have to pay attention to the time to be online at 3 PM EDT!

  • Calling family far away, I had planned to be in Texas this past week…but I was already ‘staying at home as much as possible’ a few days before I was going to get on the airplane. Talking on the telephone is the next best thing for keeping in touch until it is not as risky to be out and about in larger groups of people.

  • Making a Zentangle® butterfly. I was straightening up my office and found a few extra butterfly tiles left from last summer’s experience with summer campers. I couldn’t resist using the tile…thinking that this would be a good activity for anyone needing a quiet calm time. If you want to learn a new pattern, checkout out https://tanglepatterns.com/ . Later in the afternoon. it was warm enough that I saw a real butterfly - a cabbage white.

Update: This blog post is about a visit to Robinson early in March. Like all Howard County Recreation and Parks facilities it is closed today as part of the strategy to slow the spread of COVID-19. Check the county web site for more information.

One of the things about volunteering – there are always new things to try. Robinson Nature Center recently got some kits from the NISE (National Informal STEM Education) Network which is a community of informal educators and scientists dedicated to supporting learning about science, technology, engineering, and math (STEM) across the United States. Before I signed up for the training Robinson was offering, I looked at the NISE site. It offers many program and activities with great documentation (some kits). I was thrilled to know about the site and enjoyed the hands-on experience at the Robinson training.

Then I tried the “Exploring the Universe: Orbiting Objects” one Sunday afternoon. It included the ”gravity well” apparatus (made with PVC pipes and elbows, slip tees, PVC snap clamps, and 4-way stretch fabric). The picture shows the heaviest sphere representing the star/sun. The idea was to use spheres of various sizes and weights to simulate planets.

The activity is designed for ages 4 - adult. During the hour I was doing the activity with people coming to the nature center, the age of the children skewed young. If there were 2 children in the visiting family, the youngest was younger than 4. But it was still fun. We simply had some escaping planets and the children were not quite old enough to understand the content --- other than direct observations of the different size/weight of orbiting planets/balls and the star ‘wobble’ particularly with the heavier planet/ball orbiting. It was a learning experience for all!

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Salt Could Play a Role in Allergies | The Scientist Magazine® - Atopic dermatitis has increased more than 2-fold since the 1970s….and researchers do not attribute the increase to greater awareness or diagnosis. Now comes the observation that people with lesioned skin from atopic dermatitis (but not psoriasis) had a 30-fold higher salt level in their lesions than in their unlesioned skin or skin from healthy controls. The connection to diet is speculative at this point…but we do have higher salt in our diet now that most people had in the 1970s.

In Siberia, Toxic Black Snow Reveals the Toll of Coal Mining | Smart News | Smithsonian – Yuck! Pollutions from open-air coal pits…in the extreme. Another reason, I’m glad we’re moving away from coal powered electricity generation. I wondered if the people living in the area of black snow develop terrible lung problems.

Piling Up: How China’s Ban on Importing Waste Has Stalled Global Recycling - Yale E360 – China’s plastic imports have plummeted by 99%, mixed paper has dropped by a 33%. Recycled aluminum and glass are less affected by the ban. So now we are sending plastics to landfills, incinerators or littering the environment. Communities across the US have curtailed or halted their recycling programs. That hasn’t happened (yet) where I live in Maryland. We must learn to produce less recycle (waste) and process it more locally…not ship is someplace else in the world.

Meet the Bizarre American Bittern – Cool Green Science – It’s a type of heron that makes a strange sound (listen to the recording in this post). It is so well camouflaged that you are more likely to hear it than see it!

Bad molars? The origins of wisdom teeth – I’ve always wondered why so many people must have their wisdom teeth out. All 4 of mine were pulled when I was 19 because they were impacted. It turns out that eating a crunch/chewy diet when we are young may help the jaw grow long enough to accommodate these late molars. Wish I would have known that; I might have fed my daughter a bit differently. Too late now.
