Another High Altitude Balloon Launch

  Tom and I arrived at Brubaker Field behind Valley View  Junior High early enough to watch many of the preparations for a second balloon launch in a month (see 04/27/21). The launch was set for 10:30 AM and we arrived about 20 minutes early.

 The wind was more from the west today. But when I did my laps earlier I paid attention to the clouds moving generally north. It turns out that by the time the balloon launched it was being pushed slightly north of east.

 You can watch the balloon inflating with helium in this sequence of shots.

 Two professional photographers seemed to be covering the event. I didn't know the man on the right but the lady on the left is Carly Smith, a meteorologist with WDTN in Dayton.

 Carly moved her camera around the field getting various views of the preparations.

 About 10:20 AM a number of classes at VVJH came out of the building to watch the launch.

 The balloon is pretty much at maximum fill at this point. There will have to be plenty of room left for the gas to expand as the balloon rises into the stratosphere. It carries a parachute along with the instrument package to bring everything safely back to the ground.

 Besides the electronic instrumentation carried along, students placed scientific experiments aboard. These include, according to science teacher Jill Weaver "Martian soil simulant, seeds, UV sunscreen experiments, Orbeez [a toy], fortune telling fish [ditto] and more!"

 By 10:40 AM the countdown was made and it was off ...

 The balloon exited towards the east dangling the instrument package and parachute below. Even at great height, the stacked items could be seen moving ever higher.

 Science teacher Jill Weaver is the one we all wish we had.

 Weaver is interviewed by Smith.

 When I got home I quickly looked up the tracking website but no data was being shown. Weaver said (at 11:53 AM), "I am only picking up my SPIT tracker. We are at 47,000 feet near New Carlisle."

Results:

 It is estimated the balloon reached an altitude of 17 to 19 miles and traveled a straight-line distance of 55 miles. It was recovered in Mingo, Ohio (just NE of Urbana).

Brood X Cicadas Emerging

  It's been 17 long years but now the Brood X cicadas are emerging. I saw the first a couple of days ago and yesterday I heard the first tentative songs. When we left the house yesterday we saw a nymph working to remove himself (herself?) from his exoskeleton. It appears to be a slow and laborious process.

 This one was on our bell post and he was pulling himself out the top back of the exoskeleton. Looking into those red eyes, he seems to almost be straining. I stood there and watched him for several minutes. His movements were minute but purposeful. There was no jerking, just a slow, steady "ooze" up and away. For seconds there was no movement at all.

 A view from atop and at  an angle shows him mostly free. I wonder how his legs (those ivory-colored stringy things) can be pulled f rom the chitin legs that are so much smaller? In fact his whole body was expanding quite quickly. As he pulled out, there was no way he'd even fit back in. The case he exited was much smaller than his body now.

 A view from directly above and the cicada takes on the appearance of a small flower getting ready to open. The process is perhaps similar. I was under the impression that it was a bit of a wet, sticky process but I'm wondering now whether the threads of stickiness I seemed to observe were not just long white body parts?

 This picture was taken today (a day later) of another cicada, already free of his exoskeleton and drying himself on the back of one of our rockers. The body quickly darkens and the wings change from milky white to transparent. We found the drying time of the cicada in the first three pictures to be something less than three hours. When we returned from an excursion, he was gone. Only the case remained.

 So how do cicadas know when their 17 years are up? I have not read anything to that effect but I'll take a guess. It is not timekeeping at all but rather a series of stages that finally, after 17 years, result in "birth". There may be 17 stages or there may be many more but when they're completed, 17 years have passed and it's time to sing. The seasons are surely the background  clock.

 In 2004 both Dad and Mom were still living. In 2038 will I be? I'd be 88 (going on 89 that July). I have my doubts so I suppose, as raucous and annoying as they are I should enjoy the rare party of these noisemakers.

 It's going to be a noisy few weeks ahead.

Mound Cold War Discovery Center

  Being a ham, I was invited to attend a tour of the Mound Cold War Discovery Center with members of the Germantown Amateur Radio Society. While my friend Mike Kilroy was unable to attend, he suggested the tour would be something both Tom and I would enjoy.

 I have been an inactive amateur radio operator (WB8VQD) for many years. I think I was licensed in about 1976 and got an Advanced license at that time. I've always renewed it. Back in 1987, a month after we moved to P:inehaven, the place was burglarized and all my ham equipment was stolen. I replaced some of it for a while. But my main interest was 2 meter autopatch and that was, in my mind, superseded by cell phone.

 So all these years later, I'm still a ham but only in name.

 We got to the MCWDC before 10 AM, just as others were gathering in the parking lot.

 It's right across the road from the Miamisburg Mound. That makes it impossible to miss.

 The place has fluorescent "black lights" (UV-A) on the ceiling throughout the tour  area. It makes some of the displays a bit hard to read (though my vision isn't great) and it makes the unusual carpet literally glow like a starfield. It doesn't show well in this photo but my socks glowed an otherworldly blue.

 When I sat for a rest at one point, I tried to determine if the pattern repeats (it does).

 "Uranium ware" used uranium for coloration and the resultant glassware literally glows when the lights are turned off. This case shows a number of items with a radioactive history.

 I lived in Miamisburg from 1949 - 1980 and the Mound was always a focal point high on a ridge to the south. I wondered then what all the buildings held and what went on there. Now I know. The Mound played a major role in the development of the United States nuclear arsenal. Afterwards it developed technology for NASA.

 This is a model of an RTG (Radioisotope Thermoelectric Generator) that generated many hundreds of watts through radioactive decay and the resultant heat. Similar units were used on various interplanetary craft.

Old-Fashioned (Soft) Gingerbread

  I have another gingerbread recipe posted on the blog (use the search tool above and to the left) but I thought I'd try an old Mennonite recipe (1950). I've modified it slightly.

 This recipe makes a fairly liquid batter but it bakes perfectly in  40 minutes.

Old-Fashioned Gingerbread

1/2 cup margarine
1/2 cup light brown sugar
1 egg
1 cup light molasses
2-1/2 cups flour
1/2 teaspoon salt
1/2 teaspoon soda
1 teaspoon baking powder

1-1/2 teaspoon ginger
1 teaspoon cinnamon
1 cup boiling water

 I didn't follow the directions and it works fine doing this: Melt the margarine in a microwave and add everything except the flour. This liquid is then easily mixed with a spoon. Then add the flour last.

 The recipe calls for 35 to 40 minutes baking time at 350° but I found the full 40 minutes necessary. The batter rises beautifully. I like the cracked top. I used an 8x8" square glass pan which I greased lightly.

 Just let it cool a bit before cutting. It  can be served warm. I'll add a nice spoonful of whipped cream to the top. And strong, black coffee is almost a necessity.

 It is a deep flavor and came out darker than my usual gingerbread owing to the brown sugar instead of the called-for granulated sugar. We each had a slice last evening and it is a wonderful dessert.
