Space Debris

      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.

[...]

British firm Hempsell Astronautics has proposed a system dubbed Necropolis that would collect defunct geostationary satellites and deliver them to a single spot in the so-called "graveyard orbit." This area is situated a few hundred kilometers above the roughly 22,000-mile-high (36,000 km) geostationary ring.

Necropolis would consist of two spacecraft: a Hunter, which collects other spacecraft and pushes them up away from the geostationary ring, and a Terminus, the final parking spot for the no-longer-needed satellites. ...

     T’was three nights before Christmas and all through the Southwest, people were craning their necks upward, tracking the path of a strange flying object as it flamed across the night sky.

It was large and bright and fast. And then it was gone.

[...]

U.S. Strategic Command spokeswoman Julie Ziegenhorn told the Associated Press that Tuesday night’s fireball was an SL-4 rocket body booster from Russia that launched Monday.

Ziegenhorn didn’t indicate the booster’s ultimate fate, but speaking to Buzzfeed, Konstantin Batygin, an assistant professor of planetary science at Caltech, said it likely didn’t make it to the Earth’s surface. [...]

    Members of the Expedition 44 crew had to move out of the way of satellite debris late in the evening of Saturday, July 25. The most recent reminder that the environment above our world is becoming increasingly cluttered, did not impact crew safety or operations and, in fact, it might even get the station’s current residents a little ahead in terms of scheduled tasks. . . .

UFO Over Australia Identified

Australian Fireball Caused by Russian Space Junk (Video)

      The fireball that lit up skies over Australia Thursday night (July 10) was actually part of a Russian rocket falling back to Earth, according to media reports.

Observers throughout southeastern Australia reported seeing a bright meteor streaking through the skies at about 9:45 p.m. local time on Thursday. Based on the timing and trajectory of the object, experts have concluded that the dazzling fireball captured on video was caused by a piece of a Russian rocket that launched Tuesday (July 8).

"It looks like it was the upper stage of a Soyuz rocket that was launched a few days ago," Sydney Observatory astronomer Melissa Hulbert told the Australian Associated Press. "Apparently, the tracking and impact prediction matched, [in both] time and location, what we saw."

REBR Probes the Mystery of Reentry Forces

Space Junk

By www.aerospace.org
8-21-12

     Thousands of man-made objects currently circle the Earth, ranging in size from small flecks of paint to bus-sized satellites. At some point, all will reenter Earth’s atmosphere as their orbits decay.

The majority of them will be destroyed due to aerodynamic heating. However, some are large enough or constructed of materials strong enough to survive reentry and impact Earth’s surface.

No one has ever been injured by a reentering piece of space debris, due primarily to the fact that 70 percent of Earth’s surface is water – the majority of debris that survives reentry lands in the ocean and sinks. Those objects that have come to rest on land have done so largely in unpopulated areas.

However, there is the possibility of injury or property damage from reentering debris. In order to minimize this risk, engineers and scientists at The Aerospace Corporation have been working to better understand all the dynamic forces that are in play during reentry. Their efforts have been complicated by the fact that all data about reentry forces must be gathered remotely, from ground-based observations.

To collect more accurate reentry data, Aerospace engineers conceived, designed, and constructed the Reentry Breakup Recorder, or REBR. The basketball-sized device is launched into orbit aboard a larger spacecraft, and later intentionally deorbited, when a host spacecraft returns to Earth. The REBR gathers data as its host vehicle reenters, transmitting data to Earth for analysis. . . .

UFO Over Arabia? It's Just the Flash From Chinese Space Junk

     Bright lights in the night sky sparked UFO alerts in Saudi Arabia, but the display turned out to be a well-known space phenomenon: the fiery re-entry of some Chinese space junk.

Multiple videos of Thursday night's lights were posted on YouTube. One sighting was reported by a witness who was near the Prophet's Mosque in the western Saudi city of Medina, according to reports from the Saudi newspaper Al Sada and the Emirates24/7 website.
"I was passing just near the mosque when I saw the object ... I captured a film of it, but I could not trace it as it split into two or three parts," Al Sada quoted Fahd Al Harbi as saying.
"This was a satellite re-entry that was predicted," NBC News space analyst James Oberg said in an email. "The object was a rocket body from the Chinese communications satellite Chinasat 9, launched in 2008. It is amazing how bright the fragments can be, and when they fly horizontally and 'in formation,' they often fool people — especially pilots — into imagining they are lighted windows in aircraft, spacecraft, or even UFOs." . . .

UFO, Meteor, Space Debris? Russian Fireball Puzzles Sky-Watchers | VIDEO

     Witnesses in Russia’s Far East were astounded to see a spectacular burning object break up in the sky near Vladivostok. Though bloggers hailed it as a “meteor,” scientists are skeptical.

Photos and videos of the object posted online have provoked a debate on Russian social networks, with various ideas offered for what it might be.

“I was sitting in my car. I did not start taking pictures immediately – first I did not pay attention. It was flying soundless,” said one Internet user, who posted several photos of the event.

Witnesses said the early morning sky over Russky Island, across Vladivostok Bay, was lit up by a fireball, which later turned into a flaming line that remained in the sky for an hour and a half.

Some Russian media reported the sightings as a “meteor,” saying it was some 15 kilometers above the ground.

Other people speculated that the object could be a plane, an unmanned aircraft, a space craft or a distress flare. . . .

UFO Fireball Over Vladivostok Creates Commotion in Russian Far East 8-2-13

      Or was it a meteor lighting up the early morning sky over the Pacific port?

The flash across the sky at 7.25am caused a sensation in the Russian Far East on Sunday, with social sites exploding with theories over the dramatic flashes from the fireball. Witnesses in Vladivostok claimed it was a meteor of the kind that earlier this year struck the Urals.

Some observers said the object streaking across the sky 'looked like a plane' and others called it a UFO buzzing the flood-ridden Far East of Russia.

By later in the day, scientists had a more prosaic explanation. Vladimir Surdin, a fellow of Moscow State University's Shtenberg Institute of Astronomy, said: 'Judging by the pictures, it was an artificial object. It was moving west to east and was observed some 20 minutes after Zenit rocket was launched from Baikonur cosmodrome.'

He told RIA Novosti: 'A meteorite body usually explodes all at once, while here we see a gradual break up as happened during the MIR space station or the Colunbia shuttle fall.'

UFOs Over Chile  5-9-13



By Phil Plait

     On Thursday night, reports of a stream of UFOs over Chile and Argentina started making the rounds. It was caught on video, and it’s pretty amazing!



It’s with some relief I can say that’s not a fleet of alien spaceships bent on either enslaving the human race or possibly eating us. It's not even a swarm of meteors: what you're actually seeing there is a satellite dramatically breaking up as it re-enters the Earth’s atmosphere. And it’s even been identified: it was the Cygnus mass simulator, a payload lofted into space by the Antares rocket in April!

That was the first successful launch of the rocket by the Orbital Sciences Corporation, placing several small satellites into orbit. Eventually, the rocket will also be equipped with a cargo delivery spacecraft called Cygnus, planned to take supplies to the space station. For the first test flight on Apr. 17, Antares carried a dummy payload with the same mass as a Cygnus to test out the rocket systems.

Antares put the Cygnus dummy into a low orbit. At that altitude the atmosphere is thin, but it’s there. Over time, drag affected the satellite, lowering its orbit, dropping it into thicker air, slowing and dropping it more. On Thursday night local time (Friday morning, May 10 at about 01:00 UTC), the Cygnus dummy payload dropped down enough to experience re-entry. As it slammed through the atmosphere at several thousand kilometers per hour it compressed the air in front of it, heating it up. The pressure and heat disintegrated the structure, and it fell apart, blazing across the sky.

The timing, direction, and speed are all consistent with it being the Antares payload, so it looks like we can move this event from the "UFO" into the "IFO" category.

      READERS have continued to contact The Press to tell how they too saw a UFO in the sky over York on Wednesday evening, after we appealed for more witnesses to come forward.

Andy Cheetham, of Holgate, said he saw what looked like a very bright shooting star travel across the sky just after 9pm.

He said: “I was locking up my bike outside The Swan pub in Bishopthorpe Road,” he said. “It left a visible trail behind it, like a meteorite burning up.

“It was greenish white, moved slower than shooting stars generally do and was heading west across the city.”

Michelle Moran said she and her partner saw something falling from the sky, with a blue and red glow and travelling quite fast.

She said: “I commented that superman has just landed.” . . .

      POLICE are investigating after a member of the public reported a hole in the ground in York, which he believed was caused by debris falling from space.

A North Yorkshire Police spokeswoman said the force was called just before 1am today by someone reporting the hole in Hazel Close, New Earswick, who though it was caused by space debris.

“An officer attended the scene and found a hole in a grass verge approximately 1ft deep,” she said.

“There was no debris inside the hole and we are not in a position to confirm how or when the hole was made. The City of York Council will be made aware of the hole.”

Meanwhile, The Press Chief Reporter Mike Laycock has said that he witnessed what appeared to be a UFO over York last night.

     RUSSIAN space experts are seeking to solve the mystery of 'a UFO fragment' which crashed close to a remote village in Siberia.

The 'silver U-shaped device' weighs 200 kilos, has does not appear to be a rocket or a missile - or a remnant of earthly space technology.

‘The object found is not related to space technology. A final conclusion can be made after a detailed study of the object by experts,' said the Russian space agency Roscosmos.

Locals insist the metallic object - resembling a large shiny rubbish bin - fell from the skies. The object is six feet long and is at least partially made of titanium steel.

It's now under police guard as interest in the 'visitor' intensifies.

     A piece of space junk zoomed uncomfortably close by the International Space Station today (June 28), so close that the outpost's six-man crew had to take shelter in Russian space capsules in case of a collision.

The space debris made its closest approach to the space station at 8:08 a.m. EDT (1208 GMT), coming within 850 feet (260 meters) of the space station, where it posed a slim chance of hitting the station. However, the debris passed by the station without incident and the spaceflyers were able to re-enter the station after about a half hour.

It's a Bird! It's a Plane! It's … a UFO?

Fireball

Object in sky has observer stumped

     That suspicion crossed David Kent's mind when he spotted a bright turquoise ball in the sky Wednesday night from his Hockinson home. Kent saw the object travel across the sky before disappearing a few seconds later. He quickly dismissed the UFO idea, though.

"I don't believe in that stuff," Kent said.

Experts don't believe what Kent saw was a UFO either, but said it's likely space debris or a fireball, otherwise known as a brighter-than-normal meteor. The National Weather Service didn't have reports of anyone else seeing the object.

Jim Todd, Oregon Museum of Science and Industry's planetarium manager, said that based on Kent's description of the object, he believed it could be pieces of broken satellite. But Todd hadn't heard any other reports and said he was simply offering conjecture.

"It may have been something very natural: A shooting star, Venus or a plane in the distance," Todd said. "A blue color is characteristic of broken up space debris."

While an amateur astronomer in Spokane this week spotted the remote comet Lulin, which is passing Earth over the next few weeks, Todd said it's doubtful that's what Kent saw.

"Lulin is very faint because it's far, far away," Todd said. "And it doesn't move as fast as this person described."

Kent, who lives off Northeast 184th Street, said he was on his deck at about 9:30 p.m., when he looked south toward trees and saw a vibrant ball passing east to west. At first, he thought it was a plane, but realized it was too big to be one. He also dismissed it being a shooting star.

"I see falling stars every once in a while, but they drop off quickly," he said. "This was a pretty big sized ball."

NASA: "UFO Was Not Russian Space Debris"

UFO Nearly Misses Jetliner
NASA doubts falling Russian space debris was at fault for scaring Chilean plane

By William Atkins
ITWire.com
4-1-07


Reports have been coming in about a Lan Chile Airbus 340 with hundreds of people onboard having a near miss with a Russian space object. However, new information has been announced that disputes this story.
     According to NASA officials, the Russian space object—which supposedly made the near-miss collision with the Chilean airplane about four hours southwest of Auckland—actually re-entered the Earth’s atmosphere on schedule and well outside the time as reported by the Chilean pilot.

However, the crew of the Chilean airplane, who was flying over the Pacific Ocean from Santiago, Chile, to Auckland, New Zealand, did have a near miss with something that was described as sounding like a loud roaring noise and visually as several fireballs with falling debris passing within about 9 kilometers (6 miles) of the plane.

The actual identify of the “unidentified falling object” (UfO) is still being decided.

Earlier, Russia officials had issued an air-space warning in the southern mid-Pacific Ocean. They relayed information to the world’s aviation community that a Russian Progress 23P cargo freighter (a supply ship) had been released from the International Space Station at 2:11 p.m. EDT (eastern daylight savings time) on Tuesday, March 27, and was scheduled to re-enter the upper atmosphere over the Pacific Ocean on Tuesday at about 5:40 p.m. This procedure has been performed on numerous occasions in the past as supplies are delivered to crew members of the space station and waste materials are removed and burned up (along with the supply ship) in the Earth’s atmosphere.

This event was reported worldwide such as in the Spaceflight Now report “International Space Station supply ship undocks”.

However, the fireball was observed by the Chilean pilots about 12 hours before the time interval that the Russians reported for the Progress ship was scheduled to burn up in the atmosphere. It is now reported by the Russians that the Russian ship de-orbited and burned up in the atmosphere as scheduled. It is assumed that Chilean and New Zealand aviation officials mistakenly thought that the Russian supply ship had come down early, and was the cause of the incident.

Reports that Russia was also deorbiting an old communications satellite around this time and in this same Pacific area seem also to be wrong.

This area of the Pacific Ocean is often used as an area to crash space junk because it is almost without human presence.

NASA officials say that the Chilean pilot and crew could have seen one of many different types of objects descending into the atmosphere. They say that a meteorite is very likely to be the culprit. Around 50 meteoroids leave outer space each day and enter the Earth’s atmosphere, where they are then called meteors. Those that hit the surface of the Earth are called meteorites. Only about 150 artificially made objects re-enter the atmosphere each year.

Officials with the New Zealand’s Civil Aviation Authority (CAA) are now performing further investigations of the cause of this in-flight incident.

For additional history on continuing problems between Russia and Chile with regards to Russian space debris coming down off the Pacific coast of Chile, please read the very interesting and informative MSNBC article by NBC news space analyst James Oberg. The article called “Fireball fears stoked by space history: Chileans often see the results of Russian orbital debris” is found at http://www.msnbc.msn.com/id/17859275/page/2/.
