天問二號小行星採樣返回

2025年5月29日成功發射 此圖中的日期應是較初期時的計劃日期 天问二号主要任务目标是对小行星2016HO3进行探测、取样并返回地球,此后再对主带彗星311P开展科学探测。小行星2016HO3是人类目前发现的地球准卫星之一。天问二号任务工程目标一是突破弱引力天体表面取样、高精度相对自主导航与控制、小推力转移轨道设计等一系列关键技术,二是为小行星起源及演化等前沿科学研究提供探测数据和珍贵样品。科学目标则聚焦于测定小行星和主带彗星的多项物理参数,一是测定小行星和主带彗星的轨道参数、自转参数、形状大小、热辐射特性等物理参数,开展轨道动力学研究;二是开展小行星和主带彗星的形貌、物质组分、内部结构以及可能的喷发物等研究;三是开展样品的实验室分析研究,测定样品物理性质、化学与矿物成分、同位素组成和结构构造,开展小行星和太阳系早期的形成与演化研究。 天問二號的任務時長達到十年左右,是中國至今最長的航天任務。任務一共分為兩大部分,第一部分是探測距離地球一千多萬公里的小行星2016HO3,並在小行星上採樣。專家指,2016HO3保留著太陽系誕生之初的原始訊息,在研究太陽系形成和演化歷史方面有非常高的科學價值。 完成採樣後,天問二號會先返回地球附近,把儲存小行星樣本的返回艙釋放返回地球。整個小行星任務預計需時約兩年半。 之後天問二號會利用地球的引力彈弓效應再次飛向外太空,並用約七年時間前往位於火星和木星軌道之間,小行星帶內的主帶彗星311P。天問二號會探測這個彗星,以協助了解這類小型星體的物質結構、演化機制等。 天问二号会使用多臂协作式小天体附着取样机器人机械系统,将自己固定在小行星表面再执行采样任务,目标是取得100克以上的小行星样品。 在远程测控方面,2024年12月27日,我国在日喀则和长白山启动了两座新的40米射电望远镜,使我国的甚长基线干涉测量(VLBI)网络从“四站一中心”升级到“六站一中心”,等效口径从3200公里扩到3800公里,在X波段的分辨率提高了18%,将为我国的深空探测提供更强的助力。升级后的VLBI网络,首先服务的就是天问二号的太空征程。 Reference  CNSA Stdaily Mydrivers Rthk

咖啡的苦味 bitterness in coffee

 From dhcafe IG : 許多人誤解咖啡的苦味,認為那只是烘焙過度的結果。但其實, 咖啡的苦,更像是一棟從地基到屋頂層層鋪陳的建築。它由各種風味分子構築而成,每一層都有其結構功能與風格表現。如果我們能從宏觀到微觀去感受,就能從舌尖與舌根之間傳來的苦味訊號中,辨識出這杯咖啡的苦,是設計得當,還是結構錯置。 咖啡的苦,其實從生豆階段就已存在。咖啡因是一種直接、尖銳、幾乎無法忽略的感官訊號,就像一棟建築選用的原材料,從一開始就決定了整體的風格走向。**綠原酸(Chlorogenic acids) **則更像是原始的結構鋼材,未經加工時僅有輕微的澀與苦,卻會在烘焙過程中經由熱裂解、重組與排列,轉化為更深沉的風味基礎。當它被適當加熱,它就如彎折與定位過的鋼骨,成為支撐整棟咖啡風味建築的核心框架;若處理不當,它也可能埋下整體風味失衡的隱憂。 真正的工程,從烘焙開始。當溫度升高,綠原酸開始轉化為喹啉類(Quinides),這些分子賦予咖啡一種藥草般的苦感與清涼調性,像是垂直鋼構打下的柱腳,穩固而低調,支撐整體苦味結構的下層。它們不一定討喜,但若缺乏這一層,就如建築失去基礎支撐,容易空洞脆弱。 隨著烘焙進入深層階段,綠原酸會進一步裂解,生成苯基吲哚 (Phenylindanes),這是咖啡中最具「骨感」的苦味來源。它們彷彿構成鋼骨架間的橫向樑與對角撐桿,穩定地交織成堅固的骨架系統,並將前述的喹啉苦味明確框定在味覺結構中。這類苦味常集中於舌根與喉部,具有黏附性與延續性,就像一根埋得深的基樁,安靜卻存在感強烈。 到了風味建築的中段,我們會感受到**黑褐素(Melanoidins) ** 的登場。這些經由 Maillard 反應生成的大分子,如同灌漿的樓板與牆體,提供空間厚度與支撐質量。不僅帶來甜中帶苦的層次感,還能產生鹹感與回韻,使整體風味不再僅有骨架,而是有實感、有重量的品飲體驗。 若烘焙溫度控制不當、時間過長,風味外觀就會被**吡嗪類 (Pyrazines) **覆蓋——這些焦香苦味如同外牆清水模的表層處理,適當時能提供堅果、可可等熟香,替建築加上質感與設計語彙。但過量時,它們會覆蓋原有結構,讓所有層次都被煙燻味與碳化感所掩蓋,像是油漆太厚,掩蓋了原本的設計細節,反而成為一種負擔。 真正讓這棟「苦味建築」具有人性與可親感的,是最後的細節收尾。**內酯類(Lacto...

India Pakistan conflict

Kashmir  Post 1962 Indiatoday 22 April 2035 massacre in Indian- admistered Kashmir swarajyamag Aljazeera On April 22, 2025, in the pristine hills of Pahalgam, Jammu and Kashmir—once a symbol of the Valley’s blooming tourism industry—an act of horror unfolded that should have shocked the world’s conscience. Masked terrorists, armed and methodical, lined up a group of Indian tourists, demanded their identification, and began executing them one by one. Survivors recounted chilling details: the assailants asked names, demanded proof of religion, asked them to recite Islamic prayers and in some cases, forced victims to remove their clothes to identify whether they were circumcised—a crude test to differentiate Hindus from Muslims. Those who failed the test were shot at point-blank range. The result: 26 dead. All of them Hindus, with one victim being a Shia Muslim. And yet, as global media rushed to report the attack, the coverage offered not clarity, but camouflage. What should have bee...

Comet SWAN 25F

Tail visible in negative image, ~15' The comet is named after the SWAN camera onboard the Solar and Heliospheric Observatory (SOHO). Australian amateur astronomer Michael Mattiazzo noticed the comet in online images. SWAN is a special camera that maps hydrogen in the solar wind, which suggests this comet may be rich in the element.

Mega earthquake in Japan

NHK 31 Jan 2025 A Japanese government panel says an anticipated megaquake in the Nankai Trough along Japan's Pacific Coast could kill up to 298,000 people -- down slightly from an estimate made more than a decade ago. There is said to be a roughly 80 percent chance that a magnitude 8 to 9 quake will occur along the trough within the next 30 years. Nagoya University Professor Emeritus Fukuwa Nobuo submitted the panel's report to Disaster Management Minister Sakai Manabu. Sakai expressed his belief that damage can be reduced if measures are implemented and action is taken based on plans. He said the government will do what it can to promote the measures. The report says the quake's maximum magnitude will be on the range of nine. Seismic intensity is expected to be at least lower 6 on Japan's scale of zero to 7 in 24 prefectures, and 7 in 10 other prefectures. The panel estimates tsunami at least 10 meters high could reach Tokyo and 12 other prefectures between the Kanto...

內地啤酒被驗出嘔吐毒素 未知會否令人類患癌

  在大家最關注的安全測試當中,消委會測試8種常見於啤酒的霉菌毒素,結果顯示1款樣本「哈尔滨」麥道 檢出脱氧雪腐鐮刀菌烯醇(Deoxynivalenol,DON),檢出量為每公斤26微克,其餘樣本未有檢出霉菌毒素。脱氧雪腐鐮刀菌烯醇(DON)又稱為嘔吐毒素(vomitoxin),主要由禾穀鐮刀菌及黃色鐮刀菌產生,這些產生DON的霉菌可在土壤中找到,是穀物(尤其是小麥及玉米)的致病菌。DON最令人關注的是安全問題,有可能令人在攝入後30分鐘內出現噁心、嘔吐、腹瀉、腹痛,甚至發燒等徵狀,與其他胃腸道疾病的徵狀相若,不易分辦。國際癌症研究機構(IARC)把某些鐮刀菌衍生的毒素(包括DON)列為第3組物質,即未知會否令人類患癌。 根据深圳海关食品检验检疫技术中心在中国电子口岸数据中心深圳分中心微信公众号2023年7月的发文,DON是一种常见的真菌毒素,大多在低温、潮湿和收割季节,在谷物庄稼中慢慢生长,一般在大麦、小麦、玉米、燕麦中浓度较高,在黑麦、高粱、大米中浓度较低。 哈爾濱麥道啤酒樣本中DON的檢測含量遠低於中國國家標準(谷物及其製品)(1000μg/kg,即1ppm),也遠低於國際權威食品安全機構的相關上限標準(低於<1ppm, 即1000up/kg) 。所有產品在上市前均經過嚴格測試。
