Latest Charon Stories
A piano-sized spacecraft blasted off Thursday on a 3-billion mile journey to study Pluto, the solar system's last unexplored planet, and examine a mysterious zone of icy planetary objects at the outer edges of the planetary system.
CAPE CANAVERAL, Florida (Reuters) - NASA canceled Wednesday's launch of the U.S. space agency's first probe to Pluto after the mission control headquarters in Maryland lost power, officials said.
Bad weather forced NASA to scrub its first planned launch of an unmanned spacecraft on a nine-year voyage to Pluto, the solar system's last unexplored planet, and strong winds were threatening another delay Wednesday.
In the not-too-distant past, the planet Pluto was thought to be an odd bird in the outer reaches of the solar system because it has a moon, Charon, that was formed much like Earth's own moon was formed. But Pluto is getting a lot of company these days. Of the four largest objects in the Kuiper belt, three have one or more moons.
By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - NASA on Tuesday delayed the liftoff of its first probe to Pluto because of high winds and rescheduled the launch for Wednesday, officials at the U.S. space agency said.
By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - A massive rocket designed to give NASA's first Pluto probe a high-speed kick out of Earth's gravity was rolled out to the launch pad on Monday in preparation for liftoff.
By Irene Klotz CAPE CANAVERAL, Florida (Reuters) - NASA's first space probe to Pluto, set to lift off on Tuesday, will use radioactive plutonium pellets to power much of its expected nine-year journey to the far reaches of the solar system. The U.S.
Cliff Friedman's name may go far in Dallas real estate circles, but that doesn't come close to the 3 billion-mile trip it will begin in a few weeks.
It will be the fastest spacecraft ever launched, zooming past the moon in nine hours and reaching Jupiter in just over a year at a speed nearly 100 times that of a jetliner. Its target is Pluto - the solar system's last unexplored planet, 3 billion miles from Earth.
Observing a very rare occultation of a star by Pluto's satellite Charon from three different sites, including Paranal, home of the VLT, astronomers were able to determine with great accuracy the radius and density of the satellite to the farthest planet.
Planet Charon -- Charon is the only known satellite of Pluto. Charon was discovered by astronomer James Christy in 1978 using photographic plates which showed a bulge moving around Pluto. Christy named it after the Greek mythological figure Charon but pronounced it differently. The "ch" at the beginning of the moon's name is soft so it sounds like "Sharon," after the astronomer's wife Charlene, nicknamed Char, which both have soft ch sounds. The mythological figure's name is...
Planet Pluto -- Pluto is the ninth and smallest planet of our solar system. It was discovered by the astronomer Clyde Tombaugh at the Lowell Observatory in Arizona on February 18, 1930 (although the body was first photographed on March 19, 1915). Tombaugh was searching for a "Planet X" to explain the orbit of Neptune; further analysis, with seven decades more data about Neptune's position, has resolved the perceived anomaly without need for an additional gravitational pull on Neptune....
