NASA – Life In A Word

Poor Little Ginny

Next Tuesday, if I could drag myself out of bed before dawn, I’d see the planet Venus hole-punched into the inky sky, low and bright. If I looked further I’d probably see Mars – dim but distinctly red. And if I really did see Mars I’d be sad, because I know Ginny’s up there, all alone, waiting for someone to bring her home. I’m sorry, Ginny… I’m so sorry. Nobody’s coming for you, not for a long, long time. Rest your rotors in peace, little helicopter.

Ginny (known more formally as Ingenuity) is a brave little helicopter. She may look like a nasty bug instead of something you’d want to cuddle with, but she’s quietly been filling up the record books with her remarkable achievements. Four years ago Ginny hitched a ride to Mars on the belly of NASA rover “Perseverance”. A few months after Percy plunked down on Mars, Ginny took her “first steps”. She spun her rotor blade into a blur, rose ten feet above the Martian soil, took a quick look around, and dropped right back to where she started. That brief maneuver earned her the title: “first powered, controlled, extraterrestrial flight by any aircraft”.

Ginny may not be easy on the eyes but I’m in awe of what she accomplished in her brief time on Earth (er, Mars). I should’ve paid better attention in science class. Imagine the teacher saying, “Okay Dave, here’s your assignment. I need you to design a mini-copter that can travel to Mars, perform a few lighter-than-air maneuvers, and be able to take a few photos at the same time. You’ll be at the controls back here on earth, so whatever communication mechanism you come up with needs to work over, uh, 140 million miles.” Cue my blank stare.

The smarter-than-I-am people at California’s Jet Propulsion Labs (JPL) designed little Ginny to do all those things. What makes her ten-foot hop on Mars so remarkable is this: the atmosphere up there is less than 1% as dense as Earth’s, so there very little to hold Ginny aloft. To put it another way, earthly helicopters can only fly to 25,000 feet. Ginny had to be designed to fly to 80,000.

Let’s call her “The Little Copter That Could”, shall we? Ginny was supposed to fly five times in thirty days. Five little hops in a month’s time and her mission would’ve been considered an unqualified success. But Ginny chose to be an explorer instead of an experiment. She flew seventy-two individual missions, further and longer each time than her JPL designers ever expected. She also captured images as she flew, so scientists could better decide where on Mars they wanted big-brother Percy to rove.

Ginny was more “alive” than any helicopter I’ve ever known. She cleaned herself up after nasty Martian dust storms. Her solar panels froze unexpectedly during the rough winters, rendering her unable to fly or even take commands, yet she still radioed “wellness reports” to Percy so the JPL people would know she was (barely) there. She made three emergency landings when her sensors detected trouble. And even when one of those sensors went dead, Ginny kept her rotors a-whirling on demand.

Ginny captured the shadow of her “broken wing”

Whatever happened on Ginny’s Flight #72 two weeks ago remains a mystery, one Percy hopes to figure out as he rovers back to her location. Ginny had been close to another landing when she suddenly stopped communicating. A day later the JPL team reestablished the connection to find Ginny resting comfortably on the Martian soil. Somehow she’d still landed on her feet. Somehow however, she also damaged a rotor blade. Ginny can’t repair herself so alas, her flying days are over. Now her waiting days begin.

Admirers like me refer to Ginny as “that little extraterrestrial trailblazer”. Haters call the dormant helicopter “the first piece of trash on Mars”. As long as Percy’s in her neighborhood, Ginny will keep sending her little wellness reports (even though she’s really not so well). I just hope the scientists at JPL are already hard at work on their next mission to Mars. A brave little copter is waiting to be rescued and brought home to the Smithsonian.

Celestial Silver Dollar

I walk the dog late at night, just to be sure he doesn’t nudge me awake in the wee hours of the morning. The walk can be a chore when I’m tired but most nights it’s a quiet, peaceful stroll through our pitch-black horse pastures. We’re usually blessed with clear skies here in South Carolina, which means the stars and planets put on a display worthy of a paid ticket to an observatory. Regardless, the moment I’m out the door I’m in search of my other faithful companion: the moon.

The “heavens” offer a plethora of topics to blog about (which I have: Saturn in Of Rings and Romans or Starlink satellites in Celestial Strings of Pearls, for example) but I’m overdue with a few words about the moon. Our nearest galactic neighbor is a constant wonder to me. The moon (or is it “The Moon”?) is the reason we have ocean tides here on Earth and solar eclipses far, far away. The moon has been the target of some of the most impressive space technology and exploration in history. But let’s put the science aside, shall we? Today I’d rather just muse about the moon as its sits in the night sky, like a shiny silver dollar laid out on top of a black velvet cloth.

My favorite moons are full – the perfectly round ones – but the shadowed partials can be just as beautiful. Depending on the season and the atmosphere, the moon takes on countless looks. Some nights it rises giant above the trees, as if invisible binoculars rest before my eyes. Other nights the moon sits as an elegant crescent, a perfectly white slice of melon. Still other nights the moon doesn’t rise at all, or at least, not until well after I’m in bed. It’s a guessing game every time the dog and I head out into the dark.

I also make a game of trying to guess when the moon is full just by looking at it. On the nights just before or after it occurs the moon can still appear as full. So you have to look very carefully at the edges to decide if it’s perfectly round or not. Conveniently, the moon is full about once a month, or at least, once every month in 2024. Next year or the year after, perhaps we’ll get a “blue”: that second full moon in a calendar month. Doesn’t happen very often, of course.

Here’s a fascinating fact about the moon. It’s locked into place by the earth’s gravity, meaning it’s always showing you the same face. Try to picture the earth taking a trip around the sun (once a year or so), while it’s spinning on its own axis (once a day), while the moon is spinning around the earth. Technically the moon is rotating, just not on its own axis. So you never get to see “the dark side”.

Here’s another fact that makes me pause. If you drive across the United States from coast to coast and back again, you’re driving about 6,000 miles. Do that same drive thirty times and you’ve driven to the moon. Suddenly our celestial silver dollar doesn’t seem so far away, does it?

The next full moon (from my perspective), nicknamed “The Wolf”, is a week from this posting, on Thursday, January 25th. It’ll be the first full one of the new year. Good timing really, because some of you readers don’t make it to my blog until several days after the fact. If you’re exactly a week late, walk outside tonight after dark. A spectacular scene in the heavens awaits.

Trees We’ll Never See

A few weeks ago my wife requested a landscaper’s estimate to remove six or seven trees from the back of our property. They’ll have to knock down a few lengths of perimeter fencing so they can get their big equipment through, and they’ll make several trips to the dump with all of the branches and stumps they’ll pile up.

But when all’s said and done my wife will have the blank canvas she wants for a future riding arena for her horses. Minus a few trees, of course.

The neighbor lady won’t be happy because she’s all about keeping the trees, She drops hints here and there about “leaving things the way God intended”. She also doesn’t seem to mind the endless waste the trees generate, whether falling leaves from the oaks or cones and needles from the pines. But here’s what I want to say to her. First, we have over forty trees on our property (and thousands in the community) so losing six is just a needle in the haystack. Second, we’ll replace those trees over time, in other areas of the property. We’re already making plans to switch out the rose bushes in our driveway circle for a Flowering dogwood.

I can still hear the neighbor lady pleading, “Dave, do you know how long those trees have been standing back there?” Why yes, good neighbor, I’m sure some of them have been around a hundred years. But just like the ones that came down so our house could be built, it’s time to get rid of a few more. You sort of make an agreement with the forest when you live in it. Let me take down a few of your trees and in return I’ll care for the ones that remain.

Amy Grant, the well-known Christian singer (and most recent recipient of the Kennedy Center Honors), just released her latest single. It’s perfect for the start of spring. Trees We’ll Never See is a gentle, lilting ballad about the brevity of human life. The song covers a lot of ground in its few verses: the things we learn from our parents, the challenges we face, the value of hard work, and leaving a legacy. Amy also reminds us about the importance of faith and prayer (as she usually does). But it’s the song’s title that sticks with me. We’re all planting trees we’ll never see.

I remember talking to one of my cousins years ago, and hearing about a locked-down project he was a part of for America’s Space Administration. I can’t recall the what, where, or why of it all, but I do remember the time frame to get it done. Generations. Meaning, my cousin (and his kids, and maybe even their kids) will be long gone before the work is finished. My cousin is planting a tree he’ll never see.

Here’s my favorite lyric in the Amy Grant song:

Statues fall and glory fades but a hundred-year-old oak tree still gives shade.

That’s powerful stuff in my book. You can be somebody big or you can do something big, but what can you be or do to make the world a better place after you’re gone? I’m still working on my answer to that question.

I first covered Amy Grant a few years ago, blogging about her single I Need A Silent Night. It’s a frank anthem about seeking the Christmas spirit amidst the inevitable chaos. I’m not always struck by Amy’s lyrics but I was then and I am again now.

Here’s my final take on Amy’s song. If you’re familiar with her music you know she’s been around a long time. She released her first album in 1977, meaning almost fifty years and hundreds of songs. And in that time Amy’s style moved a little towards pop and a little towards country, but never far from Christian themes. Trees We’ll Never See could be straight out of Amy’s early years. It’s like she tapped the roots of a tree she planted decades ago, just to create a brand new one for future generations. I’ll keep that in mind whenever we plant our Dogwood.

Whirlybird Wonder

If you haven’t been following the ~~dog-and-pony~~ pony-and-dog show taking place on Mars the last couple of months, you might want to break out the telescope. Not that you’ll be able to see a car-sized rover or a toy-sized helicopter from millions of miles away. But you can see Mars itself, and then you can imagine “Percy” and “Ginny” sniffing around the red dirt and rocks up there. They’re just sampling things to see if Mars can roll out the welcome mat to humans someday.

The rover “Perseverance” is the pony in this show; “Ingenuity” the dog. I want to talk about the dog. Last July Percy hitched a nine-month ride to Mars, launching from Florida’s Cape Canaveral aboard a massive Atlas V rocket. Little Ginny hitched a ride on Percy; she the steadfast little soldier clinging to the rover’s underbelly. Considering Ginny measures only a few feet in all dimensions, it must’ve been a hang-on-for-dear-life E-ticket kind of adventure.

I’d love to make this a children’s story, but Ginny is anything but soft and cuddly. Have a look. She’s about as cute as a wasp. Consider Martian atmosphere is only 1/100th as dense as that of Earth, which means Ginny has virtually nothing to grab onto to sustain flight. But she whirls at five times the rate of a regular helicopter (2,400 rpm!), and then she rises. Product safety warning: don’t go anywhere near Ginny’s rotor blades.

Ten days ago Ginny lifted off Mars to a skyscraping height of ten feet. Then she hovered briefly before rotating about ninety degrees, kind of just observing the Mars-scape. Finally, she landed. The whole exercise lasted less than forty seconds. Big deal, right? Well, that little maneuver qualified Ginny as “the first powered controlled flight by an aircraft on a planet besides Earth”. Way to go, little wasp. You just reserved a spot in the Smithsonian after you return home.

When I picture Ginny clinging to the rover Percy, then hurtling through outer space for months on end, my middle-aged mind recalled the old Thunderbirds television show. Thunderbirds featured the Tracy family (marionettes!) and their fleet of wicked-cool space vehicles. The five Thunderbirds included a giant green supersonic carrier (“Thunderbird Two”), whose massive belly carried a yellow utility submersible (“Thunderbird Four”). Kind of like Percy carried Ginny. Trust me young(er) readers, Thunderbirds was awesome television in the 1960s… even if it was just puppets getting their strings pulled.

I’ve ridden in a helicopter exactly once in my life, on our honeymoon over the Napali Coast on the Hawaiian island of Kauai. I turned to my bride mid-flight and probably uttered some not-so-nice words as I remembered how much I dislike heights. The glass of champagne beforehand certainly helped. For me, the fear has always been a toss-up between vertigo (physical) or the idea that terra firma is far, far below me (mental). No matter the reason, heights just aren’t my cup of tea.

My acrophobia probably goes back to my first ride on a Ferris Wheel, with adolescent nightmares of slipping through the metal lap bar and taking an unplanned skydive. Or ski lifts, where a little bit of fiddling with the lap bar latch could mean the end of everything. Parasailing? (No). Hang-gliding? (Never). Hot-air balloons? (Why even ask?). Sorry – airplanes aside, and only the bigger ones mind you – I prefer my thrills securely grounded.

For all the recent broadcast news on Percy and Ginny, I can’t seem to find the part of the story where Ginny returns to Percy, who then returns to the Atlas V rocket, who then returns to Earth. I’m looking for the part about splashdowns and photo ops and ticker-tape parades – the happy-ending kind of stuff. My earlier comment about a spot in the Smithsonian may have been a little premature (can you say, “Ginny replica”?). Note to reader: if you do decide to make this a children’s story you might want to edit things a bit. Just say our little pony and dog are now asleep on Mars, waiting for their human friends to get there someday. It sounds much better than, “we just left them there”.
