Although they are complicated and expensive, Iridium's low-earth orbiting satellites have worked pretty much as billed.
Ohio is another key state where the facts contradict Romney's scorched-earth message.
"The meteor was probably about the size of an SUV, " said Donald Yeomans, manager of NASA's Near-Earth Object Program Office at the laboratory, in Pasadena, Calif.
"We would expect an event of this magnitude to occur once every 100 years, " said Paul Chodas of NASA's Near-Earth Object Program Office, in a statement.
It's hard to predict exactly how bright Pan-STARRS will be, but you should be able to see it without binoculars or telescopes, said Don Yeomans of NASA's Near-Earth Object Program.
"We would expect an event of this magnitude to occur once every 100 years on average, " Paul Chodas of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory said last week.

The waterproofing burns off during the shuttle's fiery re-entry into Earth's atmosphere, leaving the tile-encrusted spacecraft vulnerable to the elements after landing.
In a sense he has separated the quasi-mystical divine function of God's representative on Earth from the very down-to-earth job of administering the world's oldest international organisation, one which has survived two millennia of schisms, would-be reformers and wars, as well as territorial, family and political ambitions.
The asteroid orbits the Sun in 368 days - a period similar to Earth's year - but it does not orbit in the same plane as the Earth.
Roger Anderson, a geophysicist and director of the Energy Research Center at Columbia University's Lamont-Doherty Earth Observatory, says that the discoveries may have only begun.
"The problem with satellites is, we can't see through the ice sheet with satellites, " said Robin Bell, a scientist at Columbia University's Lamont-Doherty Earth Observatory who also is involved in the project.

ENGADGET: NASA finds new evidence of ice in Mercury's polar craters
But the pictures are being examined by engineers back at mission control to ensure there is no damage that could jeopardise the shuttle's re-entry through the Earth's atmosphere.
At the Stockholm environment summit of 1972 - the world's first - and at the Earth Summit here in 1992, the activists' gatherings were acknowledged as the conscience of the meeting.
That piece of insulation, which fell off 82 seconds after launch, hit the leading edge of Columbia's left wing and caused enough damage to bring about the shuttle's destruction when it re-entered the Earth's atmosphere February 1.
All of the SETI searching over the past 50 years is equivalent to examining one 8-ounce glass of water from the Earth's oceans -- a lot of human effort, but not a lot of exploration.
Solar energy can, of course, be gathered on Earth, but only about half of the sun's radiation ever makes it to the Earth's surface--the rest is either absorbed by the atmosphere or reflected back by clouds.
"It's a weirdly Earth-like place, even with this exotic combination of materials and temperatures, " Perron said.
The team has calculated that Alaskan glaciers are responsible for at least 9% of the global sea-level rise during the past century, and Alaska's glaciers raise the level of Earth's oceans by more than one-tenth of a millimetre each year.
The instrumental, desert-swept narrative sounds hauntingly evocative, but it's the thick, foreboding tone of a rusty Telecaster that links Earth's doom-laden discography.
As well as destroying such native ecosystems, deforestation also diminishes so-called "carbon sinks" -- thereby reducing the Earth's capacity to absorb and re-process atmospheric carbon dioxide -- while also adding to air pollution through the burning of land to clear it for cultivation (sugarcane fields are traditionally fired prior to harvest to remove leaves and drive away snakes).
And conservative America, once solidly sceptical, is now split over the issue, as Christians concerned about mankind's stewardship of the Earth, neo-cons keen to reduce America's dependency on the Middle East and farmers who see alternative energy as a new potential source of energy come round to the idea of cutting down on carbon.
They estimate that at least a third of the planet's mass is diamond - the equivalent of three times Earth's mass.
"He's very down-to-earth, " said Hancox, who was shot in the chest in Afghanistan in 2011.
It's just one of the tricks that has made Wendell Murphy a billionaire in the world's most down-to-earth business: pig farming.
Science editor Alan Boyle's blog: NASA's top expert on near-Earth objects says that new telescope systems are gradually getting a handle on potentially threatening asteroids.
The mission is part of Esa's Earth Explorer programme - seven spacecraft that will do innovative science in obtaining data on issues of pressing environmental concern.
My father and I were disappointed to arrive at the 1965 New York World's Fair after the scoreboard-style lighted display on the Earth's population changed from 2, 999, 999, 999 people to a bit over 3 billion.
