Mysterious Space Debris Seized by Brazil Authorities[/color]
By Chris Capps 2/26/12
A mysterious unidentified falling object has crash landed in Brazil, and video of the object has been uploaded online. The sphere's original purpose is unknown, but it appears to have been crafted artificially. And it's deeply scored with burns and abrasions that appear to have been caused during its fall. Was this object dropped from space by an accident? And could it be related to the recently destroyed Phobos Grunt? Or is it something else entirely?
Shortly after the object descended from the sky it was swarmed by some twenty villagers from nearby. By the time authorities arrived, an estimated 2,000 people from the surrounding Maranhao area had gathered to examine the mysterious piece of debris from the sky. After news of the object became more widespread, soon Brazilian authorities arrived and took the object to a barracks in Matta Roma. Without the proper equipment to analyze the device, they do not know what it might be. If it's from a satellite, it will be difficult to determine without knowing which one it could have come from.
Video of the object being handled by locals has been uploaded to Youtube. One of the interesting parts of the object is the nozzle at the end visible at the 1:18 mark. It almost looks as though it has a faucet handle like those seen on deep sea diving suits, or would be threaded to another piece of equipment. At the same time, this part of the object is too badly burned to positively identify what it is meant for.
While the mystery is by no means solved, there are a number of people looking into it that suggest it may be related to the recent reentry of Russia's Fobos Grunt. While the Russian military Air and Space Defense Forces stated that the probe reentered the atmosphere and plummeted somewhere in the Pacific Ocean, previous concerns suggested that it could have reached much closer to Argentina.
While the Grunt was never actually seen reentering or crashing into the ocean, calculations published by the Russian authorities said it would be safe. Civilian Ballistic experts, suggested that fragments of the object could have spread out, well into Brazil - including where the mystery object was found.
An UN-identified metal sphere has plunged from the sky on unsuspecting villagers in northern Brazil, causing an uproar. According to eyewitnesses, the UFO weighs about 50 kilograms and measures roughly one meter in diameter.
The sphere fell on Wednesday in a village of Riacho dos Poços in Brazilian Maranhão state. No casualties were reported apart from an unfortunate cashew tree that was severed by the object as it plunged to the ground, according to MR NOTÍCIAS, a Mata Roma news site.
Valdir José Mendes, 46, told police the sphere landed several meters from his house leaving a one-meter-deep hole in the yard.
"I heard the noise and I went out to see what caused it. I thought it was a plane that had fallen, or an earthquake," he said.
The noise was such that Mendes was too scared to go outside. However, curiosity got the better of him and he headed outside to find the cashew tree's trunk snapped in half by a mysterious metal sphere lying in a hole nearby.
Some 20 villagers joined Mendes to help him extract the object from the ground and examine it. Mendes says the sphere is hollow and if shaken some sort of liquid can be felt swishing inside. Locals quickly spread the news, as they reached the town of Mata Roma over 2,000 people flocked to see the "UFO".
"It was a huge uproar here. Some feared it was the beginning of the 2012 end of the world, others said it was 'alien', but I think it is a piece of satellite," said Max Garreto Mauro, 25, a resident of Mata Roma.
Peter Costa, the meteorologist at the National Institute for Space Research (INPE), agrees with Garetto, saying the object would probably be part of a satellite. "I'm sure this is not a weather balloon or part of it," he said as quoted by O Imparcia.
Military police confiscated the sphere and took it to the barracks in the nearby Mata Roma. They have not specified what the UFO's possible future will be. In a statement the Air Force Command said it "does not have specialized structures to perform scientific research on this type of aerial phenomena, which prevents the institution to submit an opinion on these events."
Mind your head!
In December 2011, a similar incident happened in Namibia, where a metal "Teletubby head" weighing 5.9 kilograms and measuring 35 centimeters in diameter hit the ground in the village of Omanatunga. Some Russian specialists believe the "head" was part of the third stage of the Soyuz-U rocket, launched on October 30.
Space debris stories made the headlines throughout 2011. In January, media chased the infamous Russian mars probe Phobos-Grunt across five oceans to keep up with Russia's space agency, constantly changing the possible impact location.
Earlier in October, the German Roentgen satellite split into 30 chunks, one of which weighed 400 kilograms, but those globs eventually made their way in to the Indian Ocean.
In September 2011, the Upper Atmosphere Research Satellite made headlines when it threatened to fall right onto Britain but eventually collapsed into a remote part of the Pacific Ocean

Lockheed: Prototype Space Fence tracking orbital debris
By Layer 8 on Fri, 03/09/12
Lockheed martin says its prototype S-Band Space Fence is working
Lockheed Martin says the prototype system it is developing to track all manner of space debris is now tracking actual orbiting space objects.
The Space Fence prototype includes new ground-based radars and other technologies to enhance the way the US detects, tracks, measures and catalogs orbiting objects and space debris with improved accuracy, better timeliness and increased surveillance coverage.
Lockheed Martin's prototype radar recently met a key contract requirement during a series of demonstration events by proving it could detect these resident space objects, as they are referred to by the Air Force, the company stated. On February 29, the Air Force granted its approval of Lockheed Martin's preliminary design for the system, the company stated.
The S-Band Space Fence is part of the Department of Defense's effort to track and detect space objects which can consist of thousands of pieces of space debris as well as commercial and military satellite parts. Approximately 19,000 objects larger than 10 cm are known to exist, according to NASA.
The Space Fence will use multiple S-band ground-based radars -- the exact number will depend on operational performance and design considerations -- that will permit uncued detection, tracking and accurate measurement of orbiting space objects. The idea is that the Space Fence is going to be the most precise radar in the space situational surveillance network and The S-band capability will provide the highest accuracy in detecting even the smallest space objects, the Air Force stated.
Exobots Could Search for ET and Clean Up Space Debris[/color]
Source: Penn State press release
Robotics & A.I. Posted: 04/21/12 Summary: Autonomous, self-replicating robots could help us explore the Universe, find and identify alien life, and perhaps clean up space debris in the process.
Autonomous, self-replicating robots -- exobots -- are the way to explore the Universe, find and identify extraterrestrial life and perhaps clean up space debris in the process, according to a Penn State engineer, who notes that the search for extraterrestrial intelligence -- SETI -- is in its 50th year.
"The basic premise is that human space exploration must be highly efficient, cost effective, and autonomous as placing humans beyond low Earth orbit is fraught with political economic, and technical difficulties," John D. Mathews, professor of electrical engineering, reported in the current issue of the Journal of the British Interplanetary Society.

If aliens are out there, they have the same problems we do, they need to conserve resources, are limited by the laws of physics and they may not even be eager to meet us, according to Mathews.
He suggests that "only by developing and deploying self-replicating robotic spacecraft -- and the incumbent communications systems -- can the human race efficiently explore even the asteroid belt, let alone the vast reaches of the Kuiper Belt, Oort Cloud, and beyond."
Mathews assumes that any extraterrestrial would need to follow a similar path to the stars, sending robots rather than living beings, which would explain why SETI has not succeeded to date.
"If they are like us, they too have a dysfunctional government and all the other problems plaguing us," said Mathews. "They won't want to spend a lot to communicate with us."
It is extremely difficult to broadcast into the galaxy and requires vast resources. Radio signals need to emanate in every direction to fill the sky, and the energy requirement to broadcast throughout space is quite high.
"Current infrared lasers can communicate across our solar system," said Mathews. "The problem in terms of SETI is they are highly directed beams."
Point-to-point communications using infrared signaling requires less power, but the signals are extremely directional. If ET is using laser-generated infrared signaling, we would never notice their signals because they are so tightly targeted to their destinations.
Mathews suggests that if human exploration is not possible, robots could go where many people do not want to go and do what many do not want to do, not only on Earth, but also in space.
Incredible Technology: How to Clean Up Dangerous Space Junk

The vast amount of manmade debris in orbit around Earth is untenable, but emerging and currently available technologies could be used to get these objects under control.
Humanity is generating space junk more quickly than the debris can fall back toward Earth naturally, putting satellites and spacecraft at risk of colliding with speeding pieces of debris. Unless something is done, the problem could get worse, said Donald Kessler, retired head of NASA's Orbital Debris Program Office.

"In the long term, everything will eventually break up due to collisions," Kessler told SPACE.com. "Even if you don't add anything else to the environment, the collision frequency due to random collisions will create more debris than will re-enter naturally." [The Worst Space Debris Events of All Time]
At the moment, NASA officials estimate that about 500,000 pieces of debris larger than a marble orbit the planet. There are 22,000 bits of junk as big as a softball, and there could be more than 100 million tiny fragments at least 1 millimeter across racing around Earth.

What if they were to launch some giant magnets into orbit? As the magnets zoomed around the Earth everything that is magnetic would be attracted to them and then eventually they would fall back to the Earth and disintegrate.
Trouble in orbit: the growing problem of space junk
By Dr Hugh Lewis University of Southampton
5 August 2015 From the section Science & Environment
In 2014, the International Space Station had to move three times to avoid lethal chunks of space debris. The problem also threatens crucial and costly satellites in orbit. So what is the scale of the space junk problem, and what can we do about it?
Forty-five years ago the associate director of science at Nasa's Marshall Space Flight Center, Ernst Stuhlinger, an original member of Wernher von Braun's Operation Paperclip team, was asked by Sister Mary Jucunda, a Zambia-based nun, how he could suggest spending billions of dollars on spaceflight when many children were starving on Earth.
Today, Stuhlinger's response still provides a powerful justification for the costs associated with space research.
"It is certainly not by accident that we begin to see the tremendous tasks waiting for us at a time when the young space age has provided us the first good look at our own planet," he said.
The systems on the space station that provide vital life support are also responsible for its unique vulnerability to a debris impact - a pressurised module in a vacuum might behave like a balloon if punctured
"Very fortunately though, the space age not only holds out a mirror in which we can see ourselves, it also provides us with the technologies, the challenge, the motivation, and even with the optimism to attack these tasks with confidence."
In the intervening years, the maturing space infrastructure has supported our new and ongoing efforts to tackle global health, hunger, poverty, education, disaster risk reduction, energy security and climate change.
Indeed, we have made great use of Stuhlinger's "mirror" to meet many of society's biggest challenges.
Sadly, the space environment has borne the brunt of our increasing reliance on satellites and our long-lived belief that "space is big".
More than 5,000 launches since the start of the space age, each carrying satellites for Earth observation, or communications, for example, have resulted in space becoming increasingly congested and contested. The issue has been examined for a BBC Horizon documentary on BBC Two. www.bbc.co.uk/programmes/b0656dbj
Object Falls from the Sky in Chhattisgarh. Speculations of UFO, Parts from Alien Spaceship, Satellite Debris or Plane Part
By Johny Welson - August 10, 2015
Chhattisgarh: On Friday the people of Chhattisgarh heard a loud bang and what they saw in the fields of Gaangpur was something which is not identified yet. Speculations have flooded over the internet after a journalist Rahul Pandita has shared a picture of the object quoting it “fell from the sky”. Pandita’s tweet was like this “This is what fell from the sky with a loud noise last evening at 6 pm in a field in Gaangpur, Chhattisgarh,”
We are sharing the two pictures which Rahul Pandita shared through his twitter account.
A strange piece of space junk will crash back to Earth next month
October 25, 2015 Network WritersNews Corp Australia Network
A STRANGE piece of space junk — appropriately designated WT1190F — has cycled back in its orbit and will topple back to Earth in November.
We know it is about 2m long.
It seems to be hollow — or at least bent.
We know it is on an orbit that lobbed it far beyond the moon.
Otherwise, we have no idea what it is — or who put it up there.
It’s expected to come crashing back down to Earth about 5pm on November 13 — probably in the Indian Ocean south of Sri Lanka.
The baffling bit of metal has caught the attention of Near-Earth Object researchers who are gearing up to watch its re-entry to our atmosphere closely as a means to figure out what it is — and to test the planet’s early warning system for potentially dangerous objects.
It’s not often such an entry event can be so accurately predicted.
The odd object was discovered in early October by the Catalina Sky Survey — a project intended to provide early warning of approaching comets and asteroids.
Initially, astronomers had no idea what the strange moving gleam in their cameras could be.
But tracking its trajectory back led to sightings dating back as far as 2012 being uncovered.
Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, told the science journal Nature: “(It’s) a lost piece of space history that’s come back to haunt us.”
It could be a spent rocket stage. It could be a piece of panelling from a space mission.
It may even date back to the Apollo Moon missions of the 1960s.
Astronomers aim to get detailed observations of the object as it burns up in the hope an analysis of the light spectrum produced will give clues as to what it was made of, and therefore originally used for.
Three Mysterious Objects Have Fallen From The Sky | SPAIN
Space rains junk on Spain
By channelnewsasia 11-12-15
In just over one week, three mysterious objects have fallen from the sky onto the country's southeast, prompting bomb disposal agents and experts in hazmat suits to rush over as puzzled locals looked on.
MADRID: It's raining space junk in Spain.
Rocket fuel tanks, chunks of satellites or something else entirely ... In just over one week, three mysterious objects have fallen from the sky onto the country's southeast, prompting bomb disposal agents and experts in hazmat suits to rush over as puzzled locals looked on.
First up a strange black beehive-like ball was found in Mula, a town in the region of Murcia last week.
Then at the weekend, a similar-looking, smaller object was discovered in Calasparra, just 30 kilometres (19 miles) away in the same region.
"In the early morning of the day when the first object was found, witnesses said they saw between six and seven balls of fire falling from the sky," Maria Jose Gomariz, spokeswoman for Calasparra town hall, said on Thursday.
"Maybe there were just two balls of fire and it looked like there were more ... or some may have fallen in areas where no one goes."
The discoveries sparked a stir, prompting special agents to rush over and inspect the objects, but in both cases, police determined there was no radioactivity and no danger to human health.
The mysterious space junk was transported to the city of Cartagena where there is a national vocational training centre that specialises in chemistry.
"They could be auxiliary fuel tanks belonging to a rocket," said a source at Murcia's Guardia Civil, the police force that was called to the scene.
A third object was discovered on Tuesday in Elda in the neighbouring region of Valencia, where a farmer found a long, metal-like object in his field and called the police.
This time, special agents turned up but after determining the item did not present any danger, they took it to the police station in nearby Alicante.
"It looks like a piece from an aerospace vehicle, but not a commercial plane. It could be a piece of satellite or something similar," a spokesman for Alicante police told AFP.
According to NASA, more than 500,000 pieces of debris are currently orbiting Earth, and bits of space junk plummet to our planet every year.
"Houston, we have a problem," quipped an editorial in Spain's El Pais daily.
"Some measures may have been taken to tackle the problem, but we're far from a solution," it said. "Not only is it expensive, but it's also difficult to devise a garbage collection system to go sweep in space."
The ’60s Soviet Space Probe That Crashed Into Wisconsin
When Sputnik IV hit the streets of sleepy Manitowoc, it ushered in the age of space junk.

In September 1962, something fell from aloft in Manitowoc, Wisconsin, cracking the asphalt on North 8th Street in front of what’s now the Rahr-West Art Museum.
Dennis Gintner, a Manitowoc-area resident, was a pre-teen at the time. He remembers the to-do about it.
“There was a cop that came along and kicked it off the street,” he says. “Thought it came from a garbage wagon.”
But as the pieces of the mysterious hunk of metal came to light, the town of Manitowoc realized they were dealing with something that was not of this world.
Okay, well, it was only kind of from out of this world. What fell in Manitowoc all of those years ago was a piece of Sputnik IV, a Russian probe that had spent two years in orbit. The Soviets lost control of it not long after its May 1960 launch, and the craft’s low orbit meant it would eventually be dragged down to Earth.
Sputnik IV was a test run for several human spaceflight technologies, including communications relays and a life support system with a dummy inside, according to NASA. The dummy, sadly, did not survive re-entry and become a Roswell-like urban legend. The craft was initially meant to come down to Earth but, “After four days of flight, the reentry cabin was separated from its service module and retrorockets were fired, but because of an incorrect attitude the spacecraft did not reenter the atmosphere.”
“Sputnik IV was a test Vostok spacecraft, which was intended for human spaceflight from the first,” Alice Gorman, a senior lecturer at Flinders University in South Australia, says. “Hence, unlike other Sputnik satellites, it was meant to return to the surface, ideally with its precious humanoid cargo intact.
“Throughout the early Space Age, the Soviet Union excelled at these return missions. It’s one reason why there is so little USSR material surviving in orbit from this period.”
Much of the craft burnt up on the way down, but as it fragmented, some smaller pieces were able to survive the passage through the atmosphere. What returned to Earth was probably fewer than 100 lbs of material out of a total of seven tons. Some fragments likely made it into Lake Michigan. Manitowoc is the only place where a piece seemed to make actual landfall. Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, says he’s never seen evidence of “anything but the Manitowoc chunk” coming from Sputnik IV.
What Gintner said about the cops and the garbage truck is what happened. Two police officers, Marvin Bauch and Ronald Rusboldt, found the object in the middle of the street and ignored it at first. When they came back later, they noticed it was too hot to touch and kicked it aside. As news reports of the craft’s re-entry came about, the police went back to the fragment. Eventually, that fragment made its way into the hands of the Smithsonian, which later returned it to the Russians (somewhat against the will of the Russians, “who called it a circus trick” according to Wisconsin Public Radio.) A replica of the fragment sits in Rahr-West today.
Meet the Space Custodians: Debris Cleanup Plans Emerge
By Tereza Pultarova, Live Science Contributor / April 26, 2017
Over the past 25 years, the amount of space junk orbiting Earth has grown exponentially, and the problem is bound to get worse: Some experts claim the feared Kessler Syndrome, an unstoppable cascade of collisions, is becoming a reality.
The U.S. Space Surveillance Network currently tracks some 18,000 objects larger than 4 inches (10 centimeters), of which only 1,200 are intact, operational satellites. In addition to that, there are 750,000 so-called "flying bullets" about 0.4 inches (1 cm) in size and around 150 million fragments smaller than 1 millimeter.
International guidelines recommend that operators remove spacecraft from low-Earth orbit (LEO) within 25 years from the end of the craft's mission, but only 60 percent of missions actually do that, Holger Krag, the head of the European Space Agency's (ESA) Space Debris Office, said during the final presentation at the 7th European Conference on Space Debris. The conference took place in Darmstadt, Germany, between April 18 and April 21. [Space Junk Cleanup: 7 Wild Ways to Destroy Orbital Debris]
Even if everyone complied with the regulations, it still wouldn't be enough, experts say. According to Satomi Kawamoto, of the Japan Aerospace Exploration Agency (JAXA), more than 100 objects need to be removed from LEO at the rate of five per year to stop the proliferation of fragments resulting from in-orbit collisions and explosions.
Here are some of the debris-removal concepts presented at the 7th European Conference on Space Debris.
This is not what you want to hear from the people who run the Asteroid Terrestrial-impact Last Alert System (ATLAS) project. Yet that was the message issued on January 25th by the astronomers running the ATLAS-HKO telescopes at the top of the Haleakalā volcano on the Hawaiian Island of Maui. (If your job is to look for asteroids that could kill you, it’s at least nice to know you’ll die in Hawaii.) They were watching a Near Earth Object that was about as near as you can get – 600 km (370 miles) above Earth’s surface at the perigee of its highly elliptical orbit whose apogee is 1.4 times the distance to the Moon. If they don’t know what it is and it’s orbiting the Earth, then it must the …
Black Knight Satellite!
Wouldn’t that be a great story to take our minds off of the rest of our problems? Unfortunately, A10bMLz (they had to give it a name so they could record it in the log and get paid) is not the alleged extraterrestrial satellite which has been orbiting the planet for at least 13,000 years and was supposedly detected by Nikola Tesla. However, it’s definitely a mysterious object that most people outside of the space field have probably never heard of before … an Empty Trash Bag Object (ETBO). A what?
“This suggests that it is what is known as an “empty trash bag object”: A piece of light material (probably metallic foil), left over from a rocket launch. It is not clear yet when A10bMLz has been launched.”
That observation comes from the Northolt Branch Observatories of London, which was tasked with identifying the 1 km (2.2 lb.) A10bMLz using Project Pluto astronomical software. (See a video on their Facebook page.) As one would expect, the name comes from the fact that the object behaves like a trash bag being blown about by the wind. The difference is that this ETBO Is at least 370 miles up – the highest observance of one of these rare objects.
The “trash bag” part makes it sound pretty safe. Are we in any danger from this ETBO? Well, its behavior is unpredictable and there’s no past history to use in a model.
“As with an empty trash bag blowing down the street, it may zig and zag in unpredictable ways. The nominal orbit, though, suggests that this object had a much higher perigee; it dropped to within a few hundred kilometers on this most recent perigee. I do not see any recent lunar flybys, and would not speculate on when it might hit the earth or moon or leave the earth-moon system.”
So, we’re not in any danger and neither is the Moon. Unfortunately, A10bMLz is far less intriguing that the Black Knight Satellite … unless this whole Empty Trash Bag Object is just a ruse to cover-up an accidental observation of it. Or is it an outer-space ploy by environmentalists to finally put an end to the wasteful usage of plastic bags?
At least the ETBOs are empty.
For now, it’s a good example of the ever-increasing variety of space junk in orbit that is endangering the ever-increasing number of private space flights being planned. Which will come first … the accident or the Space Junk and Empty Trash Bag Objects Collection Mission?
