NEWLY FOUND ASTEROID PASSING CLOSE TO EARTH ON SUNDAY
335 Earth will have a close encounter with an asteroid this Sunday.
BY RACHEL PAXTON-GILLILANA
The asteroid doesn't present any danger, but at only one tenth the distance between Earth and the moon, it is expected to pass "very close."
"While this celestial object does not appear to pose any threat to Earth or satellites, its close approach creates a unique opportunity for researchers to observe and learn more about asteroids," says NASA.
The asteroid is about 60 feet in size and too small to see with the naked eye. But it may be possible for amateur astronomers with a small telescope to catch a glimpse. It should safely pass over New Zealand at about 2:18 p.m. ET.
Because the idea of asteroids hurtling towards Earth is pretty scary, NASA makes it a point to continually watch for this type of near-Earth threat. Currently, it's estimated that there are over a thousand asteroids with the potential to make "threatening close approaches" to Earth, which are all closely monitored.
But this asteroid, likely due to its small size, was discovered just earlier this week. The asteroid's future orbit will bring it back to our planet's neighborhood eventually, but it doesn't appear to be a threat.
That'll do, pig...
Wait for it...
We're doomed!

Planet earth faces 100 YEARS of killer strikes starting in 2017
ASTEROIDS could rain down on the earth for 100 years, shocked experts have just warned.
A previously unknown asteroid belt has been located in deep space and is now hurtling towards our part of the solar system.
It means a 'global killer' could collide with Earth as soon as 2020, wiping out life as we know it and changing the climate for millennia.
The terrifying predictions came as NASA revealed disturbing new data showing 400 impacts are expected between 2017 and 2113, based on new observational data of objects seen in space over the past 60 days.
Most will have a maximum diameter of around 100 metres - the size of seven double decker buses - and the potential to cause significant damage.
But concerned scientists warned a colossal "monster" is also heading our way, with one 'mega' asteroid threatening earth in just SIX years.

A small meteorite landed near the international airport in the Nicaraguan capital, Managua, on Saturday night, government officials say.
Residents reported hearing a loud bang and feeling the impact, which left a crater 12m (40ft) wide and 5m deep.
Government spokeswoman Rosario Murillo said the meteorite seemed to have broken off an asteroid which was passing close to Earth.
She said international experts had been called in to investigate further.
No-one was hurt when it hit the wooded area near the international airport and an air force base.
'Like a bomb'
An adviser to Nicaragua's Institute of Earth Studies (Ineter), Wilfried Strauch, said he was "convinced it was a meteorite" which caused the impact.

Nicaragua has asked experts for help to determine whether the meteorite came from the 2014RC asteroid
Experts studying the crater said it was not clear whether the meteorite had disintegrated upon impact or had been blasted into soil.
Locals said they heard a large blast just before midnight local time and reported a burning smell.
"We thought it was a bomb because we felt an expansive wave," Jorge Santamaria told Associated Press news agency.
Ineter scientist Jose Millan said that "we need to celebrate the fact that it fell in an area where, thank God, it didn't cause any danger to the population".
Managua, which has more than a million inhabitants is densely populated.
"All the evidence that we've confirmed at the site corresponds exactly with a meteorite and not with any other type of event," he said.
"We have the seismic register which coincides with the time of impact, and the typical characteristic that it produces a cone in the place of impact," he added.
Managua was hit by a meteorite in 1997, but this time there was no tell-tale streak of light, experts said
Astronomer Humberto Saballos said the meteorite could have broken off from the 2014RC asteroid which passed Earth at the same time.
2014RC, which is the size of a house, came closest to earth at 18:18 GMT on Sunday, when it passed over New Zealand at a distance of about 40,000km (25,000 miles).
The asteroid was first discovered on 31 August and, at its closest approach, was about one-tenth of the distance from the centre of Earth to the Moon, Nasa said in a statement.
It is expected to orbit near Earth again in the future.
In February 2013, a meteorite exploded over Chelyabinsk in Central Russia, injuring more than 1,000 people.
Nasa currently tracks more than 11,000 asteroids in orbits that pass relatively close to Earth.
I'm telling you, we're doomed.
Stephen Hawking's New Doomsday Theory: 'God Particle Could Destroy Entire Universe'Quote:
Professor Stephen Hawking, often condemned and acclaimed in equal measure for his doomsday theories, has now asserted that the 'God Particle' or the Higgs boson discovered by scientist in 2012, had the potential to destroy the entire universe.
This comes as just another of his bombshell theories after the physicist had in the past, gone to the extent of warning that aliens might destroy the world and also worried that artificial intelligence might do the same. But this time, Hawking has offered a bizarre scenario where the Higgs Boson would not just merely put an end to Earth, but to the whole Universe.
I know on the ship I was on the bosun could become very unstable at high alcohol levels. "off duty" of course.Quote:
said that at very high energy levels the Higgs boson could become unstable
the universe cannot end until the Question, for which the answers is 42, is determined.
According to the article if such an event happens it spreads at light speed. So it would take a long time to affect the whole universe. If it has happened anywhere we would never see it coming. We would just be dead the instant it arrives.Quote:

I won't try to time it with a stop-watch then.
I don't think so. To my knowledge CERN is not going to cause a universe destroying phase change. Only a black hole that destroys the earth.Quote:

Here a satellite photo of a new experimental radio frequency satellite that is able to pinpoint the location of a large number of ships. These are radio signals coming from the ships, not some kind of radar. Each red dot represents a ship, a total of 52.000 ships show nicely how they are distributed all over the world. Notice also, how some of the large rivers show up with plenty of ships.

It is a long time exposure showing the flight path of the rocket. It was a launch at 1.00 AM in the night. The long time exposure plus the moonlight make it look almost like a daytime shot.

The video is offered in Ultra High Definition, the highest available to consumers. Be sure to change the settings in YouTube if your computer or television can handle it for the full effect.
The montage is made from a long sequence of still photographs taken at a resolution of 4256 x 2832 pixels at a rate of one every second. The high resolution allowed the ESA production team to create a 3840 x 2160 pixel movie, also known as Ultra HD or 4K.
Playing these sequences at 25 frames per second, the film runs 25 times faster than it looks for the astronauts in space.
The artistic effects of the light trails from stars and cities at night are created by superimposing the individual images and fading them out slowly.
Alexander Gerst is a member of the International Space Station Expedition 40 crew. He is spending five and a half months living and working on the ISS for his Blue Dot mission.

Well done India.

"India has become the first nation to reach Mars on its maiden attempt after its Mars Orbiter Mission completed its 10-month journey and successfully entered the Red Planet’s orbit. bit."
https://teakdoor.com/images/smilies1/You_Rock_Emoticon.gif
the satellite has a "please sound horn" sign on the back. (if you've never been to india, you won't get my attempt at humor.)
amazing that india is capable of this. if they can send a rocket to mars, maybe they will learn how to build a decent sidewalk someday....
but i have to also say "well done, india."
plus they did it at a fraction of the cost of the americans. (not slagging u.s.a., just stating a fact)
True, but NASA flies really brilliant scientific payloads, that's what they are good at. Though usually some of the experiments come from Europe or Japan. The achievement of India is getting there.Quote:

Mars Orbiters Safely Parked and Poised for Ringside View of Comet Flyby

MARS COMET
On Sunday, October 19, Comet C/2013 A1, also known as comet Siding Spring, will pass within about 139,500 km of Mars - less than half the distance between Earth and our moon and less than one-tenth the distance of any known comet flyby of Earth.
Space agencies of America, Europe and India have shifted their Mars orbiters to the far side of the planet to avoid any risk from the debris field of Comet Siding Spring.
The Comet C/2013 A1, also known as comet Siding Spring, will fly past Mars late on Sunday in one of the closest planetary approach by a comet, giving scientists an invaluable opportunity to learn more about the materials, including water and carbon compounds, that went into the formation of the solar system 4.6 billion years ago.
Passing within about 139,500 km of Mars, it will be at less than half the distance between Earth and our moon from the Red Planet, and less than one-tenth the distance of any known comet flyby of Earth, says Nasa.
Siding Spring's core will be closest to Mars around 2:27 pm EDT (6.27 pm GMT), hurtling at about 56 km per second.
The period of greatest risk to orbiting spacecraft will start about 90 minutes after this and last about 20 minutes, when Mars will come closest to the centre of the widening trail of dust flying from the comet's nucleus.
Siding Spring comes from the Oort Cloud, a spherical region of space surrounding our sun and occupying space at a distance between 5,000 and 100,000 astronomical units. It is composed of a swarm of giant icy objects left over from the formation of the solar system.
Siding Spring is the first comet from the Oort Cloud to be studied up close by spacecraft.
Nasa's three orbiters will gather information before, during and after the flyby about the size, rotation and activity of the comet's nucleus, the variability and gas composition of the coma around the nucleus, and the size and distribution of dust particles in the comet's tail.
India's orbiter MOM will also take shots of the comet before and after the encounter. Indian space scientists hope to get a peek into the composition of the gases in the comet's tail.
Isro expects the earliest pictures to be processed by Monday afternoon while the science data will take longer to interpret.
The comet is near the Sun for the first time and probably started its travel into the solar system nearly 4.6 billion years ago when man first appeared on earth, say experts.
This also means conditions on the comet are unaltered from that time and could give an idea about the materials that went to build the solar system.
"Siding Spring probably got knocked into the inner Solar System by the passage of a star near the Oort Cloud," Carey Lisse, from the Johns Hopkins University Applied Physics Laboratory, explained to BBC.
"So think about a comet that started to travel probably at the dawn of man and it's just now coming in."
The steep angle of its descent to the planetary ecliptic and its speed of more than 50 km per second are what points to its origins from the Oort.
Travelling at that velocity, if the comet strikes an object like a planet, the energy released would be immense.
This is why scientists like University of Maryland's Jessica Sunshine point to the need to be vigilant for these types of comets which tend to announce themselves with only a few months' warning.
Siding was first seen in January 2013.
Nasa manoeuvered its Mars Odyssey orbiter, Mars Reconnaissance Orbiter (MRO), and the latest in its fleet the Mars Atmosphere and Volatile EvolutioN (MAVEN), in order to reduce the risk of impact with high-velocity dust particles coming off the comet.
India's space agency Isro likewise manoeuvred its MOM spacecraft's orbit to ensure it avoids the comet debris.
Koteswara Rao, Isro scientific secretary, told Times of India, "We are planning to use all our scientific payloads to study the comet. At the time of its fly past, MOM will be at a distance of 1.35 lakh kilometre from the comet, thereby avoiding any damage."
Europe's orbiter too is poised for capturing some interesting ringside data on Siding.
The Mars Express will also be looking at Mars' atmosphere during the flyby besides studying the comet's composition and the interaction between the planet, comet and solar wind. The spacecraft will operate under normal conditions and will not be in the safe mode planned earlier.
Initially, the comet and its debris of gas and dust were predicted to pass much closer to Mars, posing a serious risk to the fleet of orbiting spacecraft. Later observations confirmed that the miss distance will, in fact, be more comfortable, says ESA.

Comet Siding Spring To Have 120,000mph Near Miss With Mars Today
It is a really lucky coincidence that the newest NASA Mars orbiter MAVEN that arrived only days ago has just the right scientific equipment to analyze the thin material of the comet tail. It has been built and sent out to analyze the outer atmosphere of Mars that spreads out wide into space.
Will be neat if Rover Curiosity can get images of it from the surface of Mars. That would be a first.
Waishingly Pating....
Every camera near Mars will be aimed at the comet. But there are far better ones for that purpose in orbit.
I am waiting for pictures from different sources.
I have not seen any photos of that comet worth posting. I am sure though scientists have plenty of data.
