Published August 16, 2013/ Associated Press 10,000 years ago The comet began its journey from the Oort cloud, a swath of icy objects that orbit far beyond Neptune. This is Comet ISON's first trip through the inner solar system. Beginning in August, astronomers will be able to observe the comet through ground-based telescopes once again. From early June through late-August, ISON was almost directly behind the sun as viewed from Earth, and thus could not be observed from the ground September 2013 In September, the comet will be visible near dawn in the Southern Hemisphere with binoculars. Sept. 17-Oct. 15, 2013 Launch window for the Balloon Rapid Response for ISON, or BRRISON. This balloon, which with its payload will be 671 feet tall, taller than the Washington Monument, will launch from NASA's Scientific Balloon Flight Facility in Fort Sumner, N.M. for a single day, carrying a 2.6-foot telescope and other science equipment. It will soar up to 23 miles above Earth's surface, where it can observe the comet largely unhindered by Earth's atmosphere. BRRISON will observe ISON in the near-infrared, near-ultraviolet and visible wavelength ranges, and will measure the ratio of carbon dioxide to water emissions from the comet. This ratio will be a vital diagnostic of the comet's origins. These emissions are blocked by Earth's atmosphere and cannot be measured from the ground. BRRISON is an unprecedented quick-reaction project to take advantage of the opportunity presented by the discovery of comet ISON, and is the first NASA Planetary Science Division balloon mission to observe a comet. October 2013 Mars Curiosity and Opportunity will have a view of ISON in October, with Oct. 1, 2013, being the comet's closest approach to Mars.
