Estimation of space weathering timescale on 25143 Itokawa: Implications on its rejuvenation process by Sunho Jin et al. on Sunday 04 September Context. The space weathering timescale of near-Earth S-type asteroids has been investigated by several approaches (i.e., experiments, sample analyses, and theoretical approaches), yet there are orders of magnitude differences. Aims. We aim to examine the space weathering timescale on a near-Earth S-type asteroid, Itokawa using Hayabusa-AMICA images and further investigate the evolutional process of the asteroid. Methods. We focused on bright mottles on the boulder surfaces generated via impacts with interplanetary dust particles (IDPs). We compared the bright mottle size distribution with an IDP flux model to determine the space weathering timescale. Results. As a result, we found that the space weathering timescale on Itokawa's boulder surfaces is 10$^3$ years (in the range of 10$^2$-10$^4$ years), which is consistent with the timescale of space weathering by light ions from the solar wind. Conclusions. From this result, we conclude that Itokawa's surface has been weathered shortly in 10$^3$ years but portions of the surface are exposed via seismic shaking triggered by a recent impact that created the Kamoi crater. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2209.00747v1

Hayabusa es una misión espacial no tripulada que la Agencia Japonesa de Exploración Aeroespacial (JAXA) lanzó el 9 de mayo de 2003 con el objetivo de recoger muestras de la superficie de un pequeño asteroide cercano a la Tierra llamado (25143) Itokawa. Este trozo de roca espacial mide solamente 300 metros de ancho por 700 de largo, y fue descubierto en 1998 por el telescopio LINEAR.

Una nueva investigación ha encontrado agua y materia orgánica en la superficie de una muestra de asteroide devuelta del Sistema Solar interior. La muestra de un solo grano fue devuelta a la Tierra desde el asteroide Itokawa por la primera misión Hayabusa de JAXA en 2010. La muestra nos enseña que el agua y la materia orgánica que se originan en el propio asteroide han evolucionado químicamente a través del tiempo. ¿Deseas escuchar nuestros comentarios sobre esta nota?

Hayabusa2 project manager Yuichi Tsuda and his team learned a lot from Hayabusa1, Japan’s troubled-though-successful mission that returned a sample from asteroid Itokawa. Now they are celebrating the recovery of a much larger sample from a different world: asteroid Ryugu. Dr. Tsuda joins Mat Kaplan for a fascinating, exclusive conversation about the mission’s 5-billion-kilometer journey and the great science to come.

Ten years ago, an interplanetary projectile streaked to Earth. It actually came from Earth, but it carried a cargo from beyond our planet: less than a gram of dust from the surface of an asteroid. Hayabusa was a test in patience and planning. The Japanese mission was launched in 2003. But a lot went wrong. A solar flare damaged its solar cells, which powered its engines. That delayed its arrival at the asteroid Itokawa. Once there, it was supposed to drop to the surface and fire some small “bullets” into the asteroid. It then would gather up some of the dust blasted off the surface. But that didn’t work. Instead, the craft hit the asteroid. That knocked off a few dust grains for its collectors. Hayabusa also carried a small rover. But it was deployed a bit late, so it missed the asteroid entirely. And problems with communications and other systems delayed the mission’s return to Earth. Flight controllers worked around the problems, though, and got the craft back home on June 13th of 2010. Analysis found that Hayabusa had collected about 1,500 dust grains. They showed that Itokawa probably was a fragment of a larger asteroid. They also showed that the asteroid matches the composition of a common class of meteorites. Hayabusa 2 has studied another asteroid. It successfully deployed several small rovers, and appears to have nabbed samples of the surface. It’s on its way back to Earth, with arrival scheduled for December. Script by Damond Benningfield

The asteroid Itokawa [e toe kawa] is as odd as a barbell with a 29 lb weight on one end and and 18 lb weight on the other. It was discovered in 1998 as a moving point of light in the night sky by the LINEAR project in New Mexico. It was named for the Japanese scientist whose rockets put his nations first satellite in orbit in 1970.

2017-03-20 Special EnglishThis is Special English. I&`&m Mark Griffiths in Beijing. Here is the news.Chang&`&e 5, China&`&s newest lunar probe, will bring 2 kilograms of lunar soil and rock samples back to Earth before the end of this year.The project&`&s chief said the month-long Chang&`&e 5 mission will be the most sophisticated lunar expedition China has ever made. It will face many challenges including the great number of demanding maneuvers and the complicated conditions of its landing site. The 8-metric ton probe has four components, an orbiter, lander, ascender and re-entry module. After the probe reaches lunar orbit, the components will separate into two parts. The orbiter and re-entry module will remain in orbit while the lander and ascender will descend towards the moon&`&s surface. The lander and ascender will make a soft landing, using small rockets to slow descent. They will get to work, using a drill to collect underground rocks and a mechanical arm to gather lunar soil. After two days, the ascender&`&s rocket will elevate it to lunar orbit to dock with the re-entry module. It will transfer lunar samples to the module, which will carry them to Earth. The samples are to be distributed to scientists around the country for research.This is Special English.After sending a probe to Mars in 2020, China plans to explore three asteroids and land on one of them to conduct scientific research.The "China&`&s Space Activities of 2016" white paper has been issued by the Information Office of the State Council recently. It mentioned asteroid exploration in outlining the major tasks of the country&`&s space industry in the next five years.According to the white paper, China decided to conduct expeditions to asteroids, and then to Jupiter and its satellite system after the Mars expedition.Experts say the plan is to fly a probe by an asteroid, to fly side by side with an asteroid for a period, and to land on a third one to conduct in situ sampling analysis on the surface.So far, only the United States and Japan have landed probes on asteroids. Japanese probe Hayabusa 1 landed on the asteroid Itokawa, and brought back samples to Earth.You&`&re listening to Special English. I&`&m Mark Griffiths in Beijing. Southwest China&`&s Chengdu city has started freight trains to Belarus, the first of the city&`&s planned 150 freight trains to countries including Belarus, Russia and Lithuania this year.The train, carrying 41 containers of car parts, left the provincial capital of Sichuan and will reach Minsk in 12 days after a journey of more than 8,800-kilometer.The car parts were ordered by Chinese carmaker Geely for its joint venture in Minsk.The city of Chengdu ran 460 freight trains to cities in Poland, the Netherlands and Germany last year, more than any other Chinese city. This year, the city plans to run 1,000 freight trains to Europe.Demand for rail freight between China and Europe, an alternative to slower and riskier ocean shipping and much costlier air travel, has exploded in recent years.This is Special English.China has overtaken the United States as the world&`&s largest art market amid a sharp drop in global art sales. That&`&s according to an annual report released by France-based website Artprice.com.The report found that almost 13 billion US dollars&`& worth of art was sold at art auctions across the world last year, a 22 percent decline from the 16 billion dollars of sales in 2015. Art sales in China were almost 5 billion dollars last year, accounting for 38 percent of the world&`&s gross.China had been the leading art sales market since 2010, before it was overtaken by the United State in 2015.According to the report, traditional Chinese paintings and calligraphy comprise the majority of China&`&s art sales. The highest price fetched at a Chinese auction last year was 46 million dollars for a scroll painting by an ancient painter, and it&`&s called Five Drunken Kings Return on Horses.The report noted that Chinese artists were the biggest moneymakers at auctions, with three Chinese artists on the list of top five profitable artists. Chinese artist Zhang Daqian attained the highest price, ahead of Pablo Picasso and other Chinese artists. Hong Kong has become an unmissable destination on the contemporary art map as auctions are held increasingly frequently there.You&`&re listening to Special English. I&`&m Mark Griffiths in Beijing. The Chinese language has been added to the graduation exam list by an Italian high school and 29 students will take the test this year.Sophie School, a high school specializing in linguistics, in Trento in northeastern Italy, has become the first school in the country to list Chinese as a graduation exam subject.The Chinese course has been running at the Italian school for five years, and 145 of its 910 students have chosen to study the language.The director of the school Maria Silva Boccardi said Chinese will become a global language in the future and they set up the course because many students had asked for it.She said there were only a few schools in Italy which provided trial Chinese courses in the past, but now, Chinese courses have become a crucial part of their overall teaching plan. She said the school is welcoming their pioneer batch of graduates this year.Roberto is a Sophie School student who is going to take the Chinese test before graduation. He said writing Chinese characters is the most difficult aspect of learning the language. He said when considering looking for better job opportunities overseas, China would definitely be his top choice.This is Special English.Samsung Electronics is speeding up its layout into the home appliances sector in China, with products ranging from televisions, refrigerators, washing machines, air purifiers and robot vacuum cleaners. The South Korean electronics company is continuing its efforts to put behind it the global recall of its flagship Galaxy Note 7 smartphone last year, triggered by reports of explosions involving the product.The president of Samsung Electronics China, Bae Kyung-tae, told the Samsung Forum in Shanghai that this is the 25th year since Samsung entered the Chinese market.The president said it always regarded China as one of its most important markets in the world, and invested long-term resources and advanced technology in China.The South Korean consumer electronics giant put emphasis at the forum on its QLED TV, considered as a next generation display technology after OLED displays given its enhanced picture quality.A vice-president of Samsung Electronics &`&s TV business in China, said sales of its curved-screen TV in China witnessed a growth of 87 percent year-on-year last year, while QLED sales increased by 91 percent last year, compared with the previous year.Samsung unveiled a new 75-inch QLED TV model at the Consumer Electronics Show in Las Vegas in January.

Now the news continues.An international team of experts has set a benchmark for global climate change by verifying the most extreme temperatures observed in Antarctica.An expert committee of the World Meteorological Organization Commission for Climatology monitors weather and climate extremes around the globe. It has published new records for the highest temperatures recorded in the Antarctic region.The highest temperature for the Antarctic region was observed on Jan. 30, 1982, on Signy Island.The highest temperature for the Antarctic continent was 17.5 degrees Celsius, recorded on March 24, 2015, near the northern tip of the Antarctic Peninsula.The highest temperature for the Antarctic Plateau was minus 7 degrees recorded on Dec. 28, 1980.The lowest temperature recorded by ground measurements for the Antarctic region, and for the whole world, was minus 89.2 degrees at Vostok station on July 21, 1983.Scientists say the verification of the Antarctic extremes helps to increase understanding about the Antarctic&`&s climate. Knowledge and verification of the extremes is important in the study of weather patterns, naturally occurring climate variability and human-induced climate change at global and regional scales.The newly defined records give the international community a benchmark for comparison with future observations in changing climate.This is Special English.Australian scientists said a ground-breaking research project into one family will unlock the secrets of prostate cancer.Researchers from Melbourne&`&s Menzies Institute will study the tumors of men from one Tasmanian family which has had 32 cases of prostate cancer in two generations to try and better understand the cancer.The world-first study will examine the tumors to establish if they have a genetic disruption to chromosome seven, a mutation which causes aggressive prostate cancer, and weather the disruption is genetic.Liesel FitzGerald, the lead researcher from the Menzies Institute, said the team would try to establish why the mutation occurred.FitzGerald said she has a suspicion that it is due to two genes fusing together, and unfortunately when this happens the tumors tend to grow a lot faster, and they invade other parts of the body.The researcher believes it might be an inherited mutation, and the inherited mutation in their normal cells causes gene fusion to occur.She said that the island state of Tasmania, where 500 people are diagnosed with prostate cancer each year, was the perfect place to study genetic diseases because of its small gene pool.You&`&re listening to Special English. I&`&m Mark Griffiths in Beijing. The Siberian Tiger Park in Harbin, the capital of Northeast China&`&s Heilongjiang province, is helping more than 300 Siberian tigers to lose weight. The process is being done by adding more exercise to their daily routine and cutting back on their food intake. Photos of the tigers circulated online and received wide attention from internet users, who compared the endangered big cats to orange tabby cats including comic-strip character Garfield. People questioned whether the captive tigers have been overfed by tourists at the park, the world&`&s largest Siberian tiger breeding and field training center. A chief engineer at the park, Liu Dan, said the tigers&`& obesity is a seasonal phenomenon. Liu said some tigers in the park look very chubby, but it has nothing to do with tourists feeding them. In fact, it is natural for them to devour more in order to adapt to acute weather conditions during the winter. The weight of a male Siberian tiger increases by around 10 percent in winter. To gain the weight, their food intake increases by around 30 percent to reach 8 kilograms a day for a tiger that is normally around 250 kilograms in weight.This is Special English.Dignitaries and celebrities in Hong Kong attended an event to honor Jin Yong, whose picaresque tales of martial arts heroes are popular throughout the Chinese-speaking world.The occasion marked the grand opening at the Hong Kong Heritage Museum of Jin Yong Gallery, a permanent exhibition of works by Louis Cha Leung-yung, better known by his pen name, Jin Yong.The exhibition presents almost 300 items, including manuscripts, photographs, early editions of his novels, film posters, recordings of TV series&`& theme songs and the writer&`&s personal items, including a chessboard and a camera.Jin Yong&`&s novels have been adapted more than 90 times for the big screen and television.One valuable manuscript on display is "The Smiling Proud Wanderer" initially published in Singaporean newspaper Shin Min Daily News in 1967. That is the end of this edition of Special English. To freshen up your memory, I&`&m going to read one of the news items again at normal speed. Please listen carefully.（全文见周六微信。）

Measurements of its rate of spin and shape reveal that the asteroid Itokawa has a very odd structure.

Measurements of its rate of spin and shape reveal that the asteroid Itokawa has a very odd structure.

We studied seven Itokawa particles provided by the Japan Aerospace Exploration Agency (JAXA) as first International Announcement of Opportunity (AO) study mainly using electron and synchrotron radiation X-ray beam techniques. All the analyzed particles were collected from the first-touchdown site and composed of olivine and plagioclase with traces of Ca phosphate and chromite, and do not contain pyroxenes. Optical microscopy of these particles shows minor undulatory extinction of olivine and plagioclase, suggesting minor shock metamorphism (shock stage: S2). The electron microprobe analysis shows that olivine is Fo(70-73) and plagioclase is An(13-10)Or(5-7). The synchrotron radiation X-ray diffraction (SR-XRD) analysis of olivine crystals gives cell dimensions of a = 4.708 to 4.779 angstrom, b = 10.271 to 10.289 angstrom, c = 6.017 to 6.024 angstrom, corresponding to the Fo content of Fo(similar to 70) by Vegard's law. This composition matches the result obtained by the electron microprobe analysis. The olivine compositions of the analyzed particles are consistent with those of LL chondrites. The cell dimensions of two plagioclase crystals (a = 8.180 to 8.194 angstrom, b = 12.53 to 12.893 angstrom, c = 7.125 to 7.23 angstrom, a = 92.6 degrees to 93.00 degrees, beta = 116.36 degrees to 116.75 degrees, gamma = 90.03 degrees to 90.17 degrees) indicate that their equilibration temperatures are 800 degrees C +/- 10 degrees C. This temperature is near the peak metamorphic temperature recorded by equilibrated ordinary chondrites. The size of plagioclase crystals and the homogeneity of olivine compositions indicate that their petrologic type is >= 5. We also analyzed plagioclase by SR iron X-ray absorption near-edge structure (SR-XANES) and found that its Fe3+/(Fe2+ + Fe3+) ratio is approximately 0.5. Such high Fe3+ abundance indicates the formation under a relatively oxidizing environment. Thus, all these analyses have reconfirmed that the Itokawa particles returned by the Hayabusa spacecraft are very weakly shocked equilibrated LL chondrites, which matches the results of the preliminary examination team.

I'm really screwed now.") in peace = not for war theory = idea, 理論 astrology = 占星術 an aspect = a part, a viewpoint to fulfill a requirement = to finish a required course at college mythology = 神話学 a tale = a story a horoscope = 星占い Pisces = 魚座 to get = to understand the Yin-Yang sign = the symbol related to the Chinese idea of opposites, such as male-female and light-dark a sign =星占いの「宮」 the solar system = 太陽系 the moon is made out of cheese = (Note: This is a very old belief in many cultures, and it is now a part of stories for children.) a crater = クレーター E.T. on the bike = Note: refers to the movie E.T. See this clip: http://www.youtube.com/watch?v=gTVoFCP1BLg the Apollo landings = the six NASA missions in the 1960s and 1970s when people walked on the moon a conspiracy = a false story made by a group of people for a reason, 陰謀 an important step for mankind = (Note: This is an expression used by Neil Armstrong when he first walked on the moon.) to be disputed = to be argued against or debated to back (someone up) = to support someone the diameter = the distance across a circle 1.4 million = 1,400,000 a solar flare = a sudden burst of energy from the sun to mess up = to damage to be visible = can be seen a telescope = 望遠鏡 acid rain = 酸性雨 a big deal = an important thing a rover = an exploration vehicle which can move similar to a car a billion dollars = $1,000,000,000 an eruption of glee = an explosion of happiness, cheering the asteroid belt = 小惑星帯 to be made up of = to be composed of trash = meaningless pieces, garbage leftovers = 残り物 gravity = 引力 Jupiter = 木星 to float = 浮かぶ Saturn = 土星 to get (something) and (something) mixed up = 区別が分からなくなる Titan = the second largest moon in the Solar System, around Saturn. (Note: Actually, Matthew is mistaken: Ganymede, a moon around Jupiter, is slightly larger than Titan. Titan is 50% larger than Earth's moon.) to sustain = 支える、続ける、養う to rotate = to spin, 回転する Uranus = 天王星 (Note = the English pronunciation is similar to "your anus" 肛門.) Neptune = 海王星 to kick (something) out = to reject (something) Pluto = 冥王星 (Note: Pluto used to be a planet, but a few years ago scientists decided that it was just "a dwarf planet.") a dwarf planet = 準惑星 an orbit = 軌道 oval = 楕円型の Pluto and Neptune crossed paths  = (Note: Actually, Sadie is not correct here. Neptune and Uranus are the two planets whose paths cross.) the Disney Pluto = the Disneyland dog character wealth = being rich the Kuiper Belt = カイパーベルト   debris = 破壊物の破片 (Note: The pronunciation has a silent s.) a comet = 彗星 a shooting star = a meteor = 流星 to blow up = to explode for amusement = for fun, for jokes to make sense = to sound logical and correct a tail = 尾 Halley's Comet = probably the most famous comet, which passes by earth every 75 years. The last time it passed near the earth was in 1986. astronomy = 天文学 a constellation = 星座 the Big Dipper = 北斗七星 Orion = オリオン座 (Note: The 3 bright stars in the center of the constellation are known as "Orion's belt".) a hemisphere = 半球 to invest = 投資する exploration = 探検 the final frontier = the last unexplored place (Note: this is a famous line from the American "Star Trek" TV series.) to breed = to develop, to foster, to promote to run an experiment = to conduct or to perform or to do an experiment the Hubble Space Telescope = a NASA telescope in orbit. It has made many discoveries for almost 25 years. Voyager = two NASA ships which explored the outer planets and are now leaving the solar system Hayakawa = (Note: Actually, Joe made an error: The name of the asteroid was Itokawa, and the spaceship was called Hayabusa.) dust = 塵 What do you think the future holds? = What will happen in the future? to bring back = to make alive again, to support more financially Apollo 13 = a space mission in 1969 which almost ended with deaths. The story was made into a famous movie starring Tom Hanks. every once in a while = sometimes, occasionally, from time to time all over again = one more time, repeated

Melvyn Bragg and guests discuss the unique properties of asteroids. They used to be regarded as the 'vermin of the solar system', irritating rubble that got in the way of astronomers trying to study more interesting phenomena. It was difficult or even impossible for an observer of asteroids to book time using the world's best telescopes, because they were regarded as unspectacular objects that could tell us little about the origins of the universe. However, that has all changed. It is now thought that asteroids are the unused building blocks of planets, 'pristine material' that has remained chemically unchanged since the creation of the solar system; a snapshot of matter at the beginning of time. At the moment the Japanese probe Hayabusa is 180 million miles away, pinned to the back of the asteroid Itokawa, attempting to gain our first samples of the chemical composition of an asteroid. Why did asteroids fail to form planets? How do they differ from their celestial cousins, the comets? And are either of them likely to create another impact on planet Earth? With Monica Grady, Professor of Planetary and Space Sciences, Open University; Carolin Crawford, Royal Society Research Fellow, University of Cambridge; John Zarnecki, Professor of Space Science, Open University.
