Maybe you read The New York Time’s July 16, 2015 article regarding a fragment of a Russian weather satellite passing near ISS caused one astronaut and two cosmonauts to enter a Soyuz capsule until the all clear was issued. It wasn’t the first time something like this happened, nor will it be the last.
Take a look at the above picture. That’s a graphic representation of all of the flotsam and jetsam from the entire planet’s space industries. First, blame it on the United States and Russia. Then, blame it on any nation that dared test the limits of gravity. Pretty soon, anything as minuscule as a paint fleck to a section of a satellite remained at various levels of orbit, zooming around at 175,000 mph/281,640 km/h. Occasionally bits fall to earth, succumbing to gravity and burning up harmlessly as they enter the atmosphere.
NASA and the Department of Defense keep an excellent log of anything larger than a softball and if any debris comes close enough to the ISS, both Houston and Moscow work together to plan a strategy to keep the inhabitants safe. If a threat is deemed plausible, all are instructed to go into the ISS’s lifeboats – the Soyuz capsules – in case a quick getaway is necessary.
But this poses a larger problem: what’s being done to clean up the mess? Simply ask this question to Google and you’ll get numerous responses on various sites. Space.com has an article listing 7 Wild Ways. Popular Mechanics has its own solutions. Here’s what Mental Floss has to say.
The truth is, nothing’s being done…yet. Sure, the idea’s been kicked around, maybe even a few plans surfaced. It seems getting there and back takes priority over all the mess it takes to accomplish our goals. It’s a junkyard, for sure, and like the neighbor who refuses to let go of all the cars (and their subsequent parts) owned over the past 30 years, it’s unsightly, only getting worse, and isn’t going away.
Of course, there’s been a multitude of sci-fi inspiration drawn from this. Take, for example, the recent movie “Gravity,” wherein Sandra Bullock’s character Ryan Stone finds herself floating in space untethered thanks to a run-in with remains. David Brin’s novel, “Existence” tells the story of an alien artifact tucked among the pieces of debris.
Sadly, this is a commentary on how the inhabitants of this planet choose to deal with exploration and conquering the impossible. Mt. Everest is defiled by the remains of extreme tourism. Roman ruins scattered about their former empire faced years of abuse from casual visitors seeking an up-close inspection.
SpaceX, to its credit, is developing multistage rockets that return to earth to be used in future missions. It’s facing challenges with no successes yet, but it’s not giving up and it’s getting closer with each try. They do seem to be one exception, though.
Until we learn that exploration often results in exploitation and near-irreversable damage, perhaps any further missions might benefit from following SpaceX’s lead. If not, there won’t be any room up there to put a satellite nor will be be safe to remain in any space station.

The New York Times had an excellent article on the possibilities of life Out There. You know, all that space that the universe occupies. According to Carl Sagan, there was no reason not to expect life that was comparable to humans. But if you asked the competition, evolutionary biologist Ernst Mayr, we were it. Sure, it was reasonable to expect primordial soup in other locales, with perhaps a few vegetables thrown in for variety, but Mayr was steadfast in his beliefs that the chances for humanlike life anywhere but here was slim to nil.
Naturally, there’s also that school of belief that attests to aliens living among us, including the abductees who’ve been tested and probed. Those unexplained sightings of strange ships hovering over dark highways in remote locations – that can’t be fake, eh? There has to be something real under Area 51, right? After all, why do they protect it so fiercely?
If you ask me, I’d bet the rent on life existing outside our little blue dot. Compare it to the lottery. The higher the stakes, the more players become involved. Eventually, a number’s picked and a winner is paraded before cameras as the newest bazillionaire. On occasion, though, there’s more than one winner, and regularly three or four. I’m no mathematician, but what are the chances that several people will bounce into the local gas station, drop $20.00 on gas and another $3.00 bucks for a few Powerball tickets and all come out winners? It happens. So why not expect life on other planets?
Carl Sagan maintained that sound waves generated from TV and radio drifted out among the stars would signal to intrepid space voyagers our existence. That was detailed in Contact. Those sound waves possess properties that cause them to stretch and grow as they wander further from their source. By the time those waves are detected, what discernible information remains attached to these signals would be challenging to interpret. But then again, the right exoplanetary scientist might find them an intriguing prospect: thin signals meaning what? A project to research, to turn heads into another direction to discover their source? Our planet, uncovered at last?
What’s to say there isn’t a planet with inhabitants who share the dreams of finding others, only to be told the possibilities are so incredibly remote it isn’t worth a bother?
Here’s how I see it: out there, far from Earth, a soul ponders what bioforms rose and prospered elsewhere in the abyss of space. Technologically advanced to send out space probes, this soul launches a machine capable of seeking clues, if not evidence. Time passes, the soul dies, but other scientists take this soul’s place and keep on with the vigil. Eventually, the machine wanders so far away from its home planet that even its trail of crumbs grows cold. After a great deal of time, the machine is lost to memory and passes into legend, but the language on the foreign planet evolves to the point where even the legend transforms into a mystery and eventually forgotten. Meanwhile, life on that planet succumbs to its own evolution as its inhabitants face other issues that seem more pressing or trivial, but interest in further explorations has shriveled as it’s become necessary to focus on the lack of rain, food, or a dwindling resource that is elemental to the stability of life on said planet. Or, life for the other planet’s inhabitants is fulfilling, and therefore interest plummets because all needs are met and exceeded. Curiosity fades as the inhabitants indulge in The Good Life and place high importance cultivating perpetual happiness.
On a peaceful September morning, blue skies except for drifting patches of cumulus clouds, a flash streaks across the sky. Whatever caused it crashes into a suburb of a medium-sized city, resulting in a fair amount of damage to both the landscape and the object. Upon cautious examination, its solid core leads Earth scientists to believe it’s not merely silicon. Placed in the hands of a particularly observant scientist, a barely imperceptible vibration reveals a secret only a sensitive hand would notice. “Hey,” says the Earth scientist, “I think we got something here…”
No alien spaceships, no apocalyptical force, only a simple device, badly damaged and time-worn, offers a clue to a glorious civilization similar to our own, whose own culture is seemingly lost to the wastelands of space and disbelieving souls.

Hey There!
In addition to my regularly-scheduled blog entries (which, I admit, have been rather slim as of late…sorry!), I’m dishing up a delicious serving of quick but quotable links. That is, once you take a look at what I’ve got here, you’ll be talking about them to your friends, family and blogosphere buds.
So without further ado, here they are:
1. This comes via the website Cool Infographics, which offers a wide selection of ordinary data magically transformed into wonderful graphics detailing ideas, thoughts, facts and other items of note. Randy Klum is the author of both the site and the book of the same name. The link below details 50 years of visionary sci-fi computer interfaces, or, in other words, television shows and movies’ predictions for our digital futures, starting with “Lost in Space” and continuing onto the movie “Oblivion.”
http://www.coolinfographics.com/blog/2014/8/13/50-years-of-visionary-sci-fi-computer-interfaces.html
2. There’s a whole batch of brash storm chasers following tornadoes, or hurricane hunters that fly planes directly into the eye of a hurricane to see what’s going on inside. I’ve witnessed tornadoes forming myself (not by choice) or totally nasty thunderstorms approaching while driving. Now imagine yourself aboard the Cassini spacecraft and zipping around Saturn. You’ve discovered a storm at its north pole unlike any other. Click here and prepare to be amazed…
3. Here’s a followup to the blog a wrote a few weeks ago regarding the zombie spaceship otherwise known as the International Sun-Earth Explorer-3, or ISEE-3. Unfortunately, the hardworking citizen scientists were unable to steer the craft into a direction that would bring it closer to the moon. However, I highly recommend that you not cheat yourselves out of this remarkable adventure and learn more about its extended mission and those that made it possible. Visit its website here.
4. The Martian Confederacy by Paige Braddock and James McNamara is a relatively new online graphic novel. It’s the year 3535 and three outlaws struggle to save Mars, once a former vacation destination. Read it!

Now, doesn’t that sound like a great title for a sci-fi novel?
Actually, this story’s true and it is a great story for a movie.
Way back when Jimmy Carter was president, in 1978, the International Sun-Earth Explorer 3 was launched with the mission to investigate solar wind’s interaction with the Earth’s magnetic field. Later, it was renamed the International Cometary Explorer (ICE) to study comets. In September 1985, it passed through the tail of Comet Giacobini-Zinner, and in 1986 it was tasked with the mission to observe Halley’s Comet. During the same year, three rocket burns put it on a course to position it above the moon on August 10, 2014. With the ICE so near, a space shuttle could snatch it and return it to earth, and NASA had this in mind because it planned to donate it to the National Air and Space Museum.
After a few more missions, it was retired in 1997, although it loops around the sun in a 355 day orbit. It will catch up with and pass the Earth this August 2014. But in 1999, the Deep Space Network was upgraded and the transmitters that communicated with ICE were themselves retired, although no one said this to ICE, who continued its end of the bargain by remaining open to communication. It’s sort of like being kept on hold and waiting forever, without anyone telling you that the person who put you there went home a long time ago, leaving you to listen to horrible Kenny G music in the meantime.
And really, that should have been the end of the story. But it isn’t.
Within the confines of yet another decommissioned icon, an entrepreneurial engineer named Dennis Wingo has managed the impossible. He and his team have begun communicating with ICE once more. Mr. Wingo’s company is Skycorp and it’s located in an ex-McDonalds in a decommissioned Navy base that has been repurposed for nonprofits, academia and small technology firms.
A decommissioned satellite linked with a decommissioned burger factory is kind of cool. There’s something very Max Headroom about it. I like it.
Through Mr. Wingo’s determination, a group of engineers, including those who originally worked on the project, plus a crowd funding site RocketHub, they raised approximately $160,ooo to breathe life in the old gal. And NASA’s doing its part too, donating time on its Deep Space Network to help getting ICE going again.
ICE is still doing its job out there and observing solar flares and other phenomena, as was discovered. So there was great optimism to position it over the moon as originally planned, which now requires 400 pulses to place it over the sweet spot. There’s been a few minor setbacks, but if all goes well, Mr. Wingo and his team are all set to pull ICE into a moon gravity-based slingshot into an orbit around the earth, so it can receive instructions for a new mission.
I have to admit that this story has me cheering. Why should there be a whole pile of forgotten and unused satellites and space paraphernalia after NASA and all the world’s other space agencies no longer need them? It’s an excellent opportunity for others, corporations like Skycorp but also universities and even astronomy and engineering clubs to find other purposes for them? Sure, one can say that leaves opportunities for crimes we haven’t even imagined yet. On the other hand, I’m sticking with the belief that a lot of good can come from that zombie named ICE, and its other colleagues out there.
Just imagine the stories that can be dreamed up from this real-life adventure…

I’ve seen the film “Gravity” and it’s a tension filled, zoom-above-the-earth tale meant to demonstrate how dangerous life can be in space. I also know that a portion of what was depicted in the film is not correct, but then again, how entertaining could a 100% scientifically accurate film be?
I agree. Boreville, USA Sometime, though, there really are stories that are 100% true of bravery despite obvious risks.
Take the case of Dale Gardner.
In 1984, Commander Garder and Dr. Joseph Allen used what amount to a jetpack (that’s a nitrogen gas-powered manned maneuvering unit, or MMU) to retrieve two stranded satellites, the Palapa B-2 and Westar 6, and load them into the shuttle Discovery. Both had been deployed from a shuttle and slipped into useless orbits, due to the malfunctioning of their kick motors. Gardner connected the Palapa B-2 to the shuttle’s mechanical arm but unable to load the satellite into the cargo bay.
For 90 minutes, 224 miles above the earth, both astronauts struggled to maneuver the satellite into place. Easy enough to move it around in space, it was hard to stop and it nearly collided with the Discovery. With the help Anna Fisher, another astronaut, the Palapa B-2 was eventually loaded into the cargo bay.
That left one more satellite to load, the Westar 6. Garder and Allen had fewer troubles moving it into the cargo bay this time, fortunately.
These three astronauts proved that one needn’t throw away $35 million dollars because a satellite won’t function. They were rescued and brought safely back to earth.
This was the last time MMUs were used in space.
It’s my sad duty to report that Dale Gardner died on February 19, 2014 at the age of 65. You can read a little more about his life in the New York Times, at this link: http://nyti.ms/1eDCqNk
What a wild ride it’s been. And now, he floats above us forever.
