Thousands of shooting stars per hour scraped a yellowed Martian sky last month as a comet blazed through the red planet's atmosphere at 35 miles per second.
Unfortunately, no one was there to experience the spectacular pass of Siding Spring on Oct. 19, and the remote images and data from the close encounter were not nearly so dramatic.
Still, the space agency has learned surprising things from its extremely rare observations of a comet composed of the matter that formed the inner solar system, scientists said Friday.
The comets dust slammed into the upper atmosphere, creating a massive and dense ionospheric layer, and literally changed the chemistry of the upper atmosphere of Mars, said Jim Green, director of the NASA Planetary Science Division.
The agency and its European counterpart used more than a dozen instruments and a suite of telescopes to chronicle Siding Spring's extremely close flyby, when it came within about 87,000 miles of the Martian surface.
But first, they had to make sure their orbiters - Odyssey, Mars Reconnaissance, MAVEN, and the European Space Agencys Mars Express were out of harm's way on the lee side of the comet's passage. Once the menace of hurtling particles subsided, they got to work.
But data took several days to reach Earth.
We were all wondering what we would see, realizing that the comet had faded in intensity, wondering if we would see anything at all; were all leaning into our screens, said astrophysicist Nick Schneider or the University of Colorado, who is in charge of MAVEN's Imaging Ultraviolet Spectrograph.
Amid the routine, background emissions, scientists suddenly saw this booming signal" of ionized magnesium in the atmosphere of Mars. They also detected iron, sodium, potassium, chromium, manganese, nickel and zinc -- the unambiguous signatures of a comet, Schneider said.
By looking at the brightness and extent of the ultraviolet emissions, researchers estimated that "a few tons, of dust covered at least a hemisphere of the planet," said Schneider. "So it was not an isolated impact," he added.

WASHINGTON A comet created a once-in-8-million-year fireworks show above Mars last month.
NASA data from satellites circling Mars show that when the comet, Siding Spring, skimmed the red planet, tons of comet dust bombarded the Martian sky with thousands of fireballs an hour. It warped the Martian atmosphere, leaving all sorts of metals and an eerie yellow afterglow Oct. 19.
A meteor shower from magnesium, sodium, iron and five other metals might have been so heavy that it might be even considered a meteor storm, said University of Colorado scientist Nick Schneider.
"It would have been truly stunning to the human eye," said Schneider, who was the lead instrument scientist for Maven, one of NASA's Martian satellites.
There was no video to capture the shooting stars from the surface. NASA's rovers, Opportunity and Curiosity, could take only stills. The Associated Press

It was one of the most incredible displays ever seen - yet only a handful of rovers and spacecraft were there to witness it.
Nasa has revealed the data its spacecraft gathered whenComet Siding Spring, which passed just 87,000 miles(139,500 km) by Mars on Oct. 19.
Experts describe the scene, with thousands of shooting stars per hour and the entire sky changing colour as 'mind blowing'.

Geyer won't say how much contracting out this first test flight to Lockheed Martin is saving taxpayers, though he did say it makes financial sense. He said Lockheed has expertise in areas that NASA "doesn't need to get in the middle of."
"They know how to integrate rockets. They've built rockets," he said. "So we contracted with them and we said, 'Look, I'm going to give you these objectives. I want you to test the heat shield, I want you to test the avionics. I want you to test the parachutes.'"
Lockheed and the United Launch Alliance, which is providing the rocket, even took an unusual step for a NASA space flight and licensed both the launch and re-entry with the Federal Aviation Administration. After this flight, however, NASA will take the lead.
Much of Orion borrows from the Apollo and space shuttle systems, but not everything.

"The shape is very similar to Apollo, because the physics haven't changed," Geyer said.
However, Hawes said, "Everything inside is new."
Changes include using composite materials that lighten the craft and a new cockpit reducing the 300 switches from Apollo to about 50 for Orion. Some components were created using 3-D printing.
If all goes well, another test flight will be going into a very high orbit around the moon, which will include a service module built by Airbus, and by 2021, a manned mission. NASA is less interested in returning to the moon and more interested in reaching an asteroid, towing it into lunar orbit, and using it as a potential base from which to go to Mars.
Currently the Orion program is budgeted for about $1 billion a year. Geyer hopes that continues, but he and everyone may be feeling more pressure than ever to see next month's test succeed, given failures elsewhere.

NASA has relaunched its Webby Award-winning website, Global Climate Change, with enhanced interactive features that play on any mobile device, state-of-the-art visuals, and new sections on climate change solutions and the people behind the science.
First launched in 2008, the Global Climate Change website provides easy-to-understand information about the causes and effects of climate change and the ways NASA studies them, along with the latest climate news from the agency, graphics and visualizations. The URL is: http://climate.nasa.gov
Highlights of the redesign include:
- An improved Vital Signs dashboard, providing interactive charts with continuously updated data on atmospheric carbon dioxide, sea level rise, Arctic ice extent, global temperature and other key indicators of climate change
- Visualizations of change over time from NASAs Scientific Visualization Studio
- A section that focuses on science and technology advances that are providing essential data for adapting to and mitigating the effects of climate change
- Making a Difference, a section that highlights NASAs climate researchers and the work they do
The updated site retains popular features of the earlier version, including the Images of Change gallery, the Climate Time Machine and the Eyes on the Earth data visualization tool.

Hands up if you haven't dreamt of becoming invisible at times?Researchers have too and are working on proving it's not so impossible.
Alongside some practical applications, such as self-cleaning windows, salads that contain vaccine, and tiny laptop chargers, researchers are working with nanotechnology to make invisibility, or at least a version of it, reality.
Broadly defined as the manipulation of matter on such a small scale it cannot be seen by the human eye, nanotechnology is finally opening the door to previously unexplored opportunities for technology and business.

The potential application of nanotech-enabled tiny machines has companies like Google exploring future uses especially in medicine while the University of Pennsylvania in the United States has opened a $92 million nanotechnology research hub in the centre of Philadelphia.

"Wouldn't it be wonderful if you could be like Harry Potter?" Mark Allen, scientific director of the University's Krishna P. Singh Centre for Nanotechnology, told Fairfax Media during a tour of the facility.
"Invisibility is very hard to do but it is possible using metamaterials to bend light at certain angles. It is far from Harry Potter's cloak but you can imagine applications for that."
Professor Allen is referring to work by University of Pennsylvania colleague Nader Engheta that demonstrates an early-stage example of nanotechnology a "cloaking device" that can bend light waves around an object rendering it effectively invisible.
Excerpt from:
And some of the theories out there at the moment really take some believing. Here are five:
1. The Ebola virus is an escaped bioweapon
Some believe the Ebola outbreak started with sinister armed men poisoning wells, a successful attempt at mass murder that led to arrests in Liberia. Louis Farrakhan, leader of the Nation of Islam, reckons the virus has been designed to affect only black people. If you are black or brown, you are being selected for destruction.
Others believe its an escaped military bioweapon. This theorys chief proponent is Prof Francis Boyle, a noted scholar of biowarfare and international law at the University of Illinois. In the US Prof Boyle literally wrote the rules of biowarfare. He was a member of the governments Committee of Military Use of Biotechnology and principal author of the Biological Weapons Anti Terrorism Act of 1989 which was signed into law by George Bush Snr. This isnt normal Ebola at all, he says. I believe its been genetically modified.
Boyle points to the existence of US government laboratories in Africa that are creating bioweapons under the guise of innocently working on cures. What they tell you is, We can imagine some exotic disease out there that could be used as a biological weapon, so therefore we have to look into it. The first step is to weaponise the disease so we can develop a vaccine for it. What diseases are they working on? Every type of biowarfare agent you can possibly imagine, including dengue fever and Ebola.
One of these laboratories, says Boyle, is in Kenema, Sierra Leone. Kenema is the absolute epicentre of the outbreak. Something happened there. It could have been an accident in the lab or they might have been testing an experimental vaccine [on the population] using live genetically modified Ebola and calling it something else. The proof, for Boyle, that this is a modified form of Ebola is in both the speed of its spread and the number it is killing. In the other outbreaks its a 50 per cent fatality rate and it was contained. Right here, were dealing with a 70 per cent and its not contained. All the evidence Ive been able to locate leads me to believe it came out of the Kenema lab. How high does the cover-up go? I think the people at the top know. Probably Obama too.
Critics of the theory observe that if this was an altered version of the disease, the changes to its structure would be observable to scientists. However, DNA analysis of samples sourced from 78 individuals affected by the current outbreak was recently published in the journal Science. It found this subtly different variant likely diverged from central African lineages around 10 years ago before spreading into west Africa in May. It is, in other words, perfectly natural.
2. Aeroplanes are killing us
We are being sprayed by sinister aeroplanes. We are being poisoned, en masse, from the heavens. You can tell by looking up. Why is it that some condensation trails, or contrails, left by commercial craft dissipate after a short amount of time, whereas others remain for hours and expand? And why is it that these suspected chemical trails, or chemtrails, tend to be laid out in rows of the same direction, as if theyre part of a meticulously planned pattern?
The Chemtrails Project UK is one of hundreds of websites devoted to the popular chemtrails theory. It confidently asserts the streaks are highly toxic trails left by jet planes that contain high levels of heavy metals. Their purpose? Its a geo-engineering project, perhaps an attempt to control global warming. Others say theyre brain-numbing chemical agents used to control the population.
