Podcasts about heliophysics division

Dr. Nicky Fox joined NASA in 2018 as the director of the Heliophysics Division in the Science Mission Directorate (SMD) and is now the associate administrator for NASA's SMD. 

Fox added that such studies can provide valuable information “about the workings of stars across the universe to aid in our search for habitable worlds beyond our home planet.” 福克斯补充说，此类研究可以提供“有关整个宇宙恒星运作的宝贵信息，以帮助我们寻找我们家乡星球之外的宜居世界”。NASA's statement noted the agency's earlier preparation and operations were all leading up to the latest mission. To help it get into the right position, the Parker Solar Probe received assistance from several flybys of the planet Venus. The last flyby happened on November 6, 2024. 美国宇航局的声明指出，该机构早期的准备和运作都是为了最新的任务。为了帮助它进入正确的位置，帕克太阳探测器多次飞越金星并获得了帮助。最后一次飞越发生在 2024 年 11 月 6 日。 These gravitational assists had put the spacecraft “an ideal distance” from the sun every three months, NASA explained. This distance was “close enough to study our sun's mysterious processes,” but not “to become overwhelmed by the sun's heat and damaging radiation.” 美国宇航局解释说，这些引力辅助使航天器每三个月就与太阳保持“理想距离”。这个距离“足够近，足以研究太阳的神秘过程”，但又不会“被太阳的热量和破坏性辐射淹没”。 Developers of the spacecraft say it was built with a shield made with carbon material to protect it from the extreme heat released by the sun's corona. The shield was designed to survive temperatures reaching 1,400 degrees Celsius. NASA says the data-gathering instruments are placed behind the shield. 该航天器的开发人员表示，它是用碳材料制成的防护罩建造的，以保护其免受太阳日冕释放的极端热量的影响。该防护罩设计可承受 1,400 摄氏度的高温。美国宇航局表示，数据收集仪器位于防护罩后面。 Nour Rawafi is the project scientist for Parker Solar Probe at NASA's Johns Hopkins Applied Physics Laboratory in Maryland. His team designed, built, and operates the spacecraft. He said Parker had performed as planned although it operates in “one of the most extreme environments in space.” 努尔·拉瓦菲 (Nour Rawafi) 是美国宇航局马里兰州约翰·霍普金斯应用物理实验室帕克太阳探测器的项目科学家。他的团队设计、建造和操作航天器。他表示，尽管帕克在“太空中最极端的环境之一”中运行，但它的表现仍按计划进行。Rawafi added that the mission had brought “a new golden era of space exploration, bringing us closer than ever to unlocking the sun's deepest and most enduring mysteries.” 拉瓦菲补充说，这次任务带来了“太空探索的新黄金时代，使我们比以往任何时候都更接近解开太阳最深、最持久的奥秘。” Dr. Joseph Westlake is director of NASA's Heliophysics Division, the part of the agency that studies the sun. Westlake noted that his team is preparing for more flybys in the future and hopes to capture more valuable data. Already, flybys of Venus have gathered information about the natural radio waves coming from Venus. 约瑟夫·韦斯特莱克 (Joseph Westlake) 博士是美国宇航局太阳物理学部的主任，该部门负责研究太阳。韦斯特莱克指出，他的团队正在为未来更多的飞越做准备，并希望捕获更多有价值的数据。飞越金星已经收集了有关来自金星的天然无线电波的信息。 In 2023, scientists announced they had learned new information about solar wind from data collected by Parker. Data showed that solar wind can reach speeds up to 1.6 million kilometers per hour. Solar wind forms a large magnetic barrier known as the heliosphere. It protects Earth and other planets from the continuous flow of high-energy particles from the sun's corona.2023年，科学家宣布他们从帕克收集的数据中了解了有关太阳风的新信息。数据显示，太阳风的速度可达每小时160万公里。太阳风形成一个巨大的磁屏障，称为日光层。它保护地球和其他行星免受太阳日冕持续不断的高能粒子流的影响。

A NASA probe is going to touch the Sun for ChristmasThe Parker Solar Probe is going to be making its closest approach to our Sun on Dec. 24, diving at 800,000 km/h into the corona of our star and getting within 6.5 million kilometers to the solar surface. It's the culmination of a successful mission during which the probe has measured the solar wind and flown through solar storms. We speak with C. Alex Young, the Associate Director for Science Communication in the Heliophysics Division at NASA's Goddard Space Flight Center about the highlights of the mission and what's next for the intrepid spacecraft.Pinning down the how and when Neanderthals interbred with humansStudies of Neanderthal remains have revealed that many modern humans have around two per cent Neanderthal DNA in our genomes. A study led by Leonardo Iasi, from the Max Planck Institute for Evolutionary Anthropology, shows that the mixture happened over a period of 7,000 years, lasting from about 50,000 years ago until the Neanderthals started to disappear. The Neanderthal genes that persist in our genome are tied to metabolism and immunity, which might be because humans were traveling to new places and eating new foods to which Neanderthals were already adapted. Iasi's research was published in the journal Science.What Donner and Blitzen might have been saying to RudolphResearchers from Concordia University have released a new study about caribou vocalizations, and what the animals might be signaling to each other. The vocalizations are similar to those of elk and moose, but as herd animals, caribou signaling is less about summoning mates from a distance, and more about males warning competitors to fly off elsewhere. Biologists Robert Weladji and Laura Puch analyzed recordings of these calls to search for information buried in the grunts. They found that the frequencies gave signals as to the age and size of the animal. The research was published in the journal Bioacoustics.Do crustaceans feel pain? A new study of their neural activity says yesBy monitoring the neural activity in crabs while delivering painful stimuli, researchers concluded the response they measured is associated with what we would think would be a painful experience. This study, in the journal Biology, adds to the evidence that crustaceans can sense painful stimuli as the kind of negative experience that we tend to associate with pain. Lynne Sneddon, from the University of Gothenburg led the work. Scientists are making a map of the human body accurate down to the individual cellThe Human Cell Atlas is a mammoth global project to create a detailed map of all cell types and functions in the human body, from early development to old age. While not yet complete, it's already revolutionizing how scientists can probe the human body with significant implications for future healthcare — from diagnosing diseases, to developing drugs, to ushering in a new era of personalized medical treatments. 

In this Making Leaders podcast, we hear from Bradley Williams, Acting Associate Director for Flight in the Heliophysics Division of NASA's Science Mission Directorate and one of three Promise Award Recipients in 2024. Bradley began his career in aerospace at the University of Arizona's Lunar and Planetary Laboratory, where he served as a Project Manager and Systems Engineer collaborating with faculty and research teams to identify proposal opportunities and develop spaceflight proposals for NASA. He went on to serve as the Director of Civil Space Programs at Tyvak Nano-Satellite Systems (now Terran Orbital Corporation, LLAP), a role in which he led the development of project/program management processes that prepared the company for trading on the New York Stock Exchange. While at Tyvak, Bradley led the NASA Pathfinder Technology Demonstrator CubeSats project, which included the TeraByte InfraRed Delivery (TBIRD) payload achieving a groundbreaking 200 Gigabits per second optical communications downlink. He also provided critical leadership during the design and integration phases of the CAPSTONE mission, a landmark project that continues to operate in cislunar space. Upon joining NASA, Bradley was a vital member of the OSIRIS-Rex Camera Suite (COAMS) team, contributing to both development and launch successes as a member of the systems integration and test team, management team and later as the ALTO lead and primary interface to the spacecraft team. Following the OSIRIS-Rex launch, Bradley served as Deputy Payload Manager on GUSTO, a first of its kind, balloon-borne observatory selected as a Mission of Opportunity out of NASA's Astrophysics Division. GUSTO completed the longest duration flight from Antarctica on a long duration balloon after its launch in 2023.

The Sun is the ultimate source of life in our solar system, a radiant powerhouse that bathes Earth in the energy necessary for everything from photosynthesis to weather patterns. Its warmth and light sustain us. However, the Sun's influence isn't always benign. Its solar wind—a stream of charged particles—can disrupt our technology, causing communications blackouts and GPS glitches. In this episode, Dr. Joseph Westlake, director of NASA's Heliophysics Division, joins us to shed light on why the Sun is such a critical focus for space research.

Welcome to the second of 3 podcasts for our annual Winter Series. As with our Summer Series, we’ll be bringing you recent important news updates and talks on topics we think you’ll find interesting from other creators. Our regular interviews will resume on January 14th. On December 4th NASA announced the first results from the Parker Solar Probe mission. The mission is a first of its kind with the probe flying closer to the sun than any other spacecraft before. It’s a risky mission, but with rich scientific rewards expected. And in this news conference, the principal investigators confirm some long thought theories about our star, but also reveal some new mysteries. The seven year mission continues, and just five days ago the spacecraft successfully completed its second flyby of Venus. NASA says the spacecraft used Venus to slow itself down, approaching the planet at a distance of about 3,009 km (1,870 miles) from Venus’s surface during the second gravity assist of the mission. This gravity assist maneuver adjusted Parker Solar Probe’s trajectory to set it up for its fourth orbit around the Sun, or perihelion, which will occur on January 29. Listen in.
