A piece of the Earth’s crust dated as 4.4 billion years old, has been discovered on a ranch in Jack Hills, Australia, just north of Perth. The zircon crystal, which only measures 400 micrometers long, is a translucent red that appears blue when bombarded with electrons. The dating of the crystal indicates that the Earth cooled much more rapidly than previously thought and may have had water at a much earlier age.
China’s Jade Rabbit lunar rover, also known as Yutu, suffered a potentially mission ending breakdown which prevents it from hibernating during the 14-day long lunar night. If it does not enter hibernation mode, the rover may cease to function. The Chinese space agency issued a light-hearted news release, written as if by the rover, to announce the issue.
The ESA’s Herschel Space Observatory has detected signs of water vapor being ejected from Ceres, the largest asteroid. The two plumes, which are in different regions of the asteroid, are probably sublimation of ice into clouds of vapor or ice volcanoes. Scientists have believed that Ceres might have water for more than thirty year, but this was the first proof.
China landed the Chang’e 3 probe on the Moon at Sinus Iridium on December 14 at 8:11 a.m. EST. The probe carries the lunar rover Yutu and makes China the third country, along with the US and the Soviet Union, the successfully send probes to the Moon. This is the first soft landing on the moon since the Soviet Union’s Luna 24 landed in 1976. China launched Chang’e 3 on December 2 and it has been in Lunar orbit since December 7.
In 1953, Fritz Leiber published The Wanderer, about a planet that moved through interstellar space, without a sun to orbit. Scientists have now announced the discovery of PSO J318.5-22, a gas giant located 80 light years from Earth that does not orbit a primary. With only six times the mass of Jupiter, the planet is believed to be 12 million years old, relatively young for a planet. The lack of a primary makes it easier for scientists to study the planet.
Former JPL Director Bruce C. Murray (b.1931) died on August 29. Murray served as director of the Jet Propulsion Laboratory from 1976 through 1982, a period that saw the launch of the Voyager probes. While serving as director, Murray co-founded, along with Carl Sagan and Louis Friedman, the Planetary Society, in 1980, to support research related to astronomy, planetary science, exploration, public outreach, and political advocacy.
In Heinlein’s 1956 novel Time for the Stars, he described an experiment in which one identical twin was sent on a space mission while the other stayed at home. NASA has now announced that it will be using a set of twins to examine the effects of prolonged space flight on the human body. Astronaut Scott Kelly, veteran of two shuttle missions and a former ISS Commander, will spend a year aboard the ISS for NASA longest spaceflight ever. His brother, Mark Kelley, who flew four shuttle missions, including as commander of Endeavour‘s final flight, will remain on Earth as the control. Scott Kelly is scheduled to join the ISS crew in March 2014.
The Russian Olympic Committee has announced that all gold medals awarded on February 15, 2014 at the Winter Olympics in Sochi, Russia will contain pieces of the meteorite that exploded over the Russian city of Chelyabinsk on February 15, 2013. Seven sets of gold medals will be awarded on the anniversary of the meteor strike, including Men’s 1,500 meter Speedskating, Women’s 1,000m and Men’s 1,500m Short Track, Women’s Cross-Country Skiing Relay, Men’s K-125 Ski Jump, Women’s Super Giant Slalom, and Men’s Skeleton.
Jeff Bezos has confirmed that the engines his team discovered on the ocean floor in March are in fact the engines which launched the Apollo XI to the Moon in 1969. His announcement, based on the discovery of part numbers at the Kansas Cosmosphere and Space Center in Hutchinson, comes one day before the 44th anniversary of the first lunar landing, accomplished by Neil Armstrong and Buzz Aldrin using the engines Bezos has recovered.
Astronomer Mark Showalter has discovered a fourteenth moon of Neptune while examining old imagery of the planet taken by the Hubble Space Telescope. The new moon, currently called S/2004 N 1, is believed to be twelve miles in diameter and orbiting Neptune at a distance of 65,400 miles, between the orbits of the moons Larissa and Proteus. This is the sixth moon Showalter has been involved in discovering, including the two recently named Plutonian moons, Styx and Kerberos.
