Sean bienvenidos japonistasarqueológicos, ha una noticia arqueológica nipona en esta ocasión nos trasladamos a la protohistoria nipona y para ser más precisos al periodo Kofun(こふんじだい) 250 al 592 d.c finales de siglo VI para ser más exactos, dicho esto pónganse cómodos que empezamos. - Se ha descubierto un grupo de tumbas con túneles subterráneos que datan de la primera mitad del Medio Kofun Miyakonojo Aihara, localizados en la ciudad de Miyakonojo, prefectura de Miyazaki. Muchos de ellos tienen las cámaras funerarias en donde se consagran los cadáveres, pero uno de los 22 que se encontraron tenía una forma inusual, ya que una piedra bloqueaba el medio del hoyo horizontal. - Las paredes están pintadas con tinte rojo y otra con dos fosas que conducían a la misma cámara funeraria. Las tumbas subterráneas de entrada horizontal, que se descubrieron en la ciudad de Ebino alrededor del siglo IV ya que era lo que se creía anteriormente, pero ahora es posible que muchas de ellas las estuvieran construyendo al mismo tiempo. - El segundo sondeo que se realizó en mayo del año pasado 2022, se habían excavado aproximadamente unos 4.200 metros cuadrados. También se encontraron unos artículos funerarios como: espadas de hierro y puntas de flecha en la cámara funeraria y en las fosas. El suelo se rellenará a partir de enero del próximo año y se completará un informe a finales del año fiscal 2023. - 日本の考古学者の皆さん、今回は日本の原始時代、正確には6世紀末の古墳時代（西暦250年〜592年）に話を移します。 - 宮崎県都城市にある古墳時代中期前半の地下トンネルを持つ古墳群「都城相原」が発見された。その多くは死体を安置する埋葬室を備えているが、発見された22基のうち1基は、横穴の真ん中を石が塞いでいるという珍しい形をしていた。 - 壁には赤い染料が塗られ、もうひとつには同じ埋葬室につながる2つの穴がある。えびの市で発見された横穴式地下古墳は、従来考えられていたように4世紀頃に発見されたが、現在では多くの古墳が同時期に造られていた可能性がある。 - 昨年5月に行われた第2回目の調査では、約4,200平方メートルを発掘していました。また、鉄剣や矢じりなどの墓誌類も埋葬室や穴から発見された。来年1月から土壌の埋め戻しを行い、2023年度中に報告書を完成させる予定です。 - Welcome Japanese archaeologists, this time we move to the Japanese protohistory and to be more precise to the Kofun period(こふんじだい) 250 to 592 AD at the end of the 6th century to be more exact, that said make yourselves comfortable and let's start. - A group of tombs with underground tunnels dating back to the first half of the Middle Kofun Miyakonojo Aihara, located in Miyakonojo City, Miyazaki Prefecture, have been discovered. Many of them have the burial chambers where corpses are enshrined, but one of the 22 that were found had an unusual shape, with a stone blocking the middle of the horizontal hole. - The walls are painted with red dye and another with two pits leading to the same burial chamber. Underground tombs with a horizontal entrance, which were discovered in the city of Ebino around the 4th century as it was previously believed, but it is now possible that many of them were being built at the same time. - The second survey, which was carried out in May last year 2022, had excavated approximately 4,200 square metres. Some grave goods such as iron swords and arrowheads were also found in the burial chamber and in the pits. The soil will be backfilled from January next year and a report will be completed by the end of fiscal year 2023.

Why We Celebrate Search and Rescue Technologies on 4/06

Today (4/06), we celebrate the special radio frequency transmitted by emergency beacons to the international search and rescue network. 

This 406 MHz frequency, used only for search and rescue, can be "heard" by satellites hundreds of miles above the ground! The satellites then "forward" the location of the beacon back to Earth, helping first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies.

Our Search and Rescue office, based out of our Goddard Space Flight Center, researches and develops emergency beacon technology, passing the technology to companies who manufacture the beacons, making them available to the public at retail stores. The beacons are designed for personal, maritime and aviation use.

The search and rescue network, Cospas-Sarsat, is an international program that ensures the compatibility of distress alert services with the needs of users. Its current space segment relies on instruments onboard low-Earth and geosynchronous orbiting satellites, hundreds to thousands of miles above us. 

Space instruments forward distress signals to the search and rescue ground segment, which is operated by partner organizations around the world! They manage specific regions of the ground network. For example, the National Oceanic and Atmospheric Administration (NOAA) operates the region containing the United States, which reaches across the Atlantic and Pacific Oceans as well as parts of Central and South America.

NOAA notifies organizations that coordinate search and rescue efforts of a 406 MHz distress beacon's activation and location. Within the U.S., the U.S. Air Force responds to land-based emergencies and the U.S. Coast Guard responds to water-based emergencies. Local public service organizations like police and fire departments, as well as civilian volunteers, serve as first responders.

Here at NASA, we research, design and test search and rescue instruments and beacons to refine the existing network. Aeronautical beacon tests took place at our Langley Research Center in 2015. Using a 240-foot-high structure originally used to test Apollo spacecraft, our Search and Rescue team crashed three planes to test the survivability of these beacons, developing guidelines for manufacturers and installation into aircraft.

In the future, first responders will rely on a new constellation of search and rescue instruments on GPS systems on satellites in medium-Earth orbit, not hundreds, but THOUSANDS of miles overhead. These new instruments will enable the search and rescue network to locate a distress signal more quickly than the current system and achieve accuracy an order of magnitude better, from a half mile to approximately 300 feet. Our Search and Rescue office is developing second-generation 406 MHz beacons that make full use of this new system.

We will also incorporate these second-generation beacons into the Orion Crew Survival System. The Advanced Next-Generation Emergency Locator (ANGEL) beacons will be attached to astronaut life preservers. After splashdown, if the Orion crew exits the capsule due to an emergency, these beacons will make sure we know the exact location of floating astronauts! Our Johnson Space Center is testing this technology for used in future human spaceflight and exploration missions.

If you're the owner of an emergency beacon, remember that beacon registration is free, easy and required by law.
