Кръвоносна система, растеж на растенията, пространствена ориентация - много експерименти в условията на безтегловност се провеждат на борда на самолет Airbus A310 Zero-G във Франция, които могат да послужат за пилотирани космически мисии, но да подпомогнат изследванията и на Земята.
@astro_physiccs Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. #gravity #universe #space #solarsystem #xh #xuhuong #astronomy #astronomical #distances #astrophysics #earth #physics #knowledge #science ♬ Memory Reboot - VØJ & Narvent
Както и на Международната космическа станция (МКС), тези експерименти целят да ни освободят от гравитацията, която всяко тяло на земята изпитва и която "маскира" действието на други сили.
@shaowguay The International Space Station (ISS) is a large spacecraft in orbit around Earth. It is a collaboration between five space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ISS is a research laboratory where scientists from all over the world conduct experiments in a weightless environment. **What is the purpose of the ISS?** The primary purpose of the ISS is to conduct scientific research in a weightless environment. The ISS is also used to train astronauts for future space missions. **How fast does the ISS move?** The ISS orbits Earth at a speed of 27,744 kilometers per hour. This is necessary to maintain its orbit. **How does the ISS orbit Earth?** The ISS orbits Earth in a low-Earth orbit, approximately 400 kilometers above the surface. It takes the ISS about 92 minutes to orbit Earth once. **What happens when astronauts repair the ISS outside the spacecraft?** When astronauts repair the ISS outside the spacecraft, they use jetpacks to move around. The jetpacks provide thrust to counteract the effects of gravity. **Does the ISS need to be propelled by engines constantly?** No, the ISS does not need to be propelled by engines constantly. The ISS's orbital velocity is sufficient to maintain its orbit. However, the ISS does use engines to make small adjustments to its orbit, such as to avoid collisions with other objects in space. **How do astronauts breathe on the ISS?** Astronauts on the ISS breathe oxygen that is produced by the station's oxygen generators. The oxygen generators use electricity to split water into oxygen and hydrogen. **Is the Earth flat?** No, the Earth is not flat. The Earth is a sphere with a radius of about 6,371 kilometers. **สถานีอวกาศนานาชาติ (ISS)** เป็นยานอวกาศขนาดใหญ่ที่โคจรรอบโลก เป็นความร่วมมือกันระหว่างห้าหน่วยงานอวกาศ: NASA (สหรัฐอเมริกา), Roscosmos (รัสเซีย), JAXA (ญี่ปุ่น), ESA (ยุโรป) และ CSA (แคนาดา) ISS เป็นห้องปฏิบัติการวิจัยที่นักวิทยาศาสตร์จากทั่วโลกทำการทดลองในสภาวะไร้น้ำหนัก **วัตถุประสงค์ของ ISS คืออะไร** วัตถุประสงค์หลักของ ISS คือการทำวิจัยทางวิทยาศาสตร์ในสภาวะไร้น้ำหนัก ISS ยังใช้เพื่อฝึกอบรมนักบินอวกาศสำหรับภารกิจในอวกาศในอนาคต **ISS เคลื่อนที่เร็วแค่ไหน** ISS โคจรรอบโลกด้วยความเร็ว 27,744 กิโลเมตรต่อชั่วโมง ซึ่งจำเป็นสำหรับการรักษาห้วงโคจรของมัน **ISS โคจรรอบโลกได้อย่างไร** ISS โคจรรอบโลกในวงโคจรต่ำรอบโลก สูงจากพื้นผิวประมาณ 400 กิโลเมตร ใช้เวลาประมาณ 92 นาทีในการโคจรรอบโลก 1 ครั้ง **เกิดอะไรขึ้นเมื่อนักบินอวกาศซ่อมแซม ISS นอกยานอวกาศ** เมื่อนักบินอวกาศซ่อมแซม ISS นอกยานอวกาศ พวกเขาจะใช้เป้เจ็ตเพื่อเคลื่อนที่ไปรอบ ๆ เป้เจ็ตให้แรงขับเพื่อต่อต้านผลกระทบของแรงโน้มถ่วง **ISS ต้องการแรงขับจากเครื่องยนต์ตลอดเวลาหรือไม่** ไม่ ISS ไม่ต้องการแรงขับจากเครื่องยนต์ตลอดเวลา ความเร็วรอบวงโคจรของ ISS เพียงพอที่จะรักษาห้วงโคจรของมันไว้ อย่างไรก็ตาม ISS ใช้เครื่องยนต์ในการปรับแต่งห้วงโคจรเล็กน้อย เช่น เพื่อหลีกเลี่ยงการชนกับวัตถุอื่นในอวกาศ **นักบินอวกาศหายใจบน ISS ได้อย่างไร** นักบินอวกาศบน ISS หายใจออกซิเจนที่ผลิตโดยเครื่องกำเนิดออกซิเจนของสถานี เครื่องกำเนิดออกซิเจนใช้ไฟฟ้าแยกน้ำออกเป็นออกซิเจนและไฮโดรเจน **โลกแบนหรือไม่** ไม่ โลกไม่แบน โลกเป็นทรงกลมที่มีรัศมีประมาณ 6,371 กิโลเมตร

При експеримента KRABS учени изследват последиците от смущенията в кръвоносната система на хората в космоса. "Целта на експеримента е да изследва агрегацията на червени кръвни телца, когато кръвообращението се забави от микрогравитацията", обясни Томас Подгорски, директор по изследванията на френския Национален център за научни изследвания в университета Гренобъл-Алпи. Изследване показа моменти на стагниране на кръвообращението при членове на екипажа на МКС, с риск от образуване на тромби.
@know.art.aldo @brilliant.org were brilliant enough to sponsor this brilliant video. It’s an app with hands-on lessons on physics, math, CS, and such. Can recommend. You get 30 days free with the link in my bio. And their daily challenges are always free I believe.

За онези, които се питат доколко са полезни експериментите, ръководителят на проекта за параболични полети в Националния център за научни изследвания отговаря, че амбицията е "да се правят изследвания в отговор на търсенето на знание". Би било илюзорно да се смята, че повечето от тези изследвания засягат само полетите, каза Себастиен Рукет. Свидетелство за това е експеримент в лабораторията COMETE, който изследва ефекта от гравитацията върху човешките възприятия за пространство и време. Те са обект на изследванията на Жил Клеман от близо четиридесет години, специално с проучвания върху астронавтите на МКС.

Техните вестибуларни апарати "се адаптират много бързо към липсата на гравитация". Но тази адаптация се измерва, след като са прекарали два дни в космоса, докато стигнат до МКС, докато корабът, с който пътуват, се скачи със станцията и те се настанят. На борда на Airbus A310 Zero-G целта на експеримента е да измери ефекта от микрогравитация върху човешкото тяло още от първите минути в безтегловност. Целта ни е да се опитаме да разберем как успяваме да се адаптираме така бързо, за да можем да разберем дали има рехабилитационни техники, които можем да използваме при лечението на пациенти с проблеми във вестибуларния апарат, каза изследователят. В университета на Кeн изследват пациенти с разстройства в равновесието, "идентични с тези, изпитвани от астронавтите в началото на полета и при завръщането им на Земята".

Екологични въпроси също имат своето място в експериментите. Проектът HAMSTER изследва енергийния обмен между източник на светлина и листата на растения. EVAPER е експеримент на лаборатория MADIREL, който изследва микрофизиката на облаците, приложима в климатологията. Екип на университета на Екс-Марсилия и Националния център за научни изследвания се опитва да измери времето за изпаряване на капчиците в облаците под въздействието на инфрачервена радиация.
@gozerog Hit your New Year's resolutions by working against twice the gravity! 🤣💪 With our parabolic method, your Zero-G flight is not only floating in ZERO gravity. There are also moments where you'll experience 1.8x gravity. 😱 #gozerog #zerog #zerogexpereince #zerogexperience #zerogravity #weightless #weightlessness #gozerogravity #zerogravity #flyzerog ♬ original sound - .
