Europe’s new launcher, Ariane 6 uses liquid oxygen and hydrogen as fuel to lift it off the ground and into space. This fuel is chilled to -150°C which allows more propellant to be loaded into the rocket with more fuel from the engine.
But Ariane would not get far without the boosters that provide the most thrust by far.
In order to control the direction of Ariane 6 after launch, the nozzles on the boosters and main stage can swivel to keep it on course. This is no easy feat as Ariane 6 is 56 m tall and controlled at the bottom, so it is a careful balancing act.

Last week, Ariane 6’s central core – the main body of the rocket – was stood tall at the launch zone and connected to its two solid-fuel boosters. This exciting moment means only one thing: it’s the start of the first launch campaign.
The main stage and upper stage make up the core stage, and they were autonomously driven at 3 km/h from the rocket assembly building to the launch pad, 800 m away. Then lifted by a crane, the Ariane 6 core was stood upright on the launch table.
The two boosters were transported to the launch pad on a specially designed truck and then configured with the rocket body, now holding it upright.
Ariane 6 is due to launch in summer 2024. The heavy-lift rocket will inaugurate a new era of autonomous European space transportation, powering Europe into space to realise its ambitions on the world stage. It will lift off from a modern launch complex at Europe’s Spaceport in French Guiana, carrying with it not just a variety of spacecraft, but also European goals for prosperity and autonomy.

As we approach the launch of ESA’s EarthCARE mission, we caught up with some of the scientists, engineers and experts behind the mission.
With the climate crisis increasingly tightening its grip, ESA’s Earth Cloud Aerosol and Radiation Explorer mission (EarthCARE) will shed new light on the complex interactions between clouds, aerosols and radiation in Earth’s atmosphere.
EarthCARE is the largest and most complex Earth Explorer mission. It comes at a critical time in the development of kilometre-scale resolution, global climate models and will provide an important contribution to an improved understanding of cloud convection and its role in Earth’s radiation budget.
EarthCARE is an ESA mission, but it has been developed as a cooperation between ESA and JAXA, the Japanese Space Agency.
This video features interviews with: Pavlos Kollias from Stony Brook University – McGill University, Thorsten Fehr, EarthCARE Mission Scientist at ESA, Robin Hogan, Senior Scientist at ECMWF, Dirk Bernaerts, EarthCARE Project Manager at ESA, Kotska Wallace, Mission and Optical Payload Manager at ESA, Tomomi Nio, EarthCARE Mission Manager at JAXA, Eiichi Tomita, EarthCARE/CPR Project Manager at JAXA, Ulla Wandinger, Senior Scientist at Leibniz Institute for Tropospheric Research and Bjoern Frommknecht, EarthCARE Mission Manager at ESA.

At 1:47 a.m. EST (6:47 UTC) on Nov. 16, 2022, NASA’s Orion spacecraft launched atop the Space Launch System (SLS) rocket from historic Launch Pad 39B at NASA’s Kennedy Space Center on a path to the Moon, officially beginning the Artemis I mission.
Over the course of 25.5 days, Orion performed two lunar flybys, coming within 80 miles (129 kilometers) of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles (435,000 kilometers) from our home planet. NASA’s Orion spacecraft successfully completed a parachute-assisted splashdown in the Pacific Ocean at 9:40 a.m. PST (12:40 p.m. EST) as the final major milestone of the Artemis I mission.
Artemis I set new records of performance, exceeded efficiency expectations, and established new safety baselines for humans in deep space. This is a prelude to what comes next—following the success of Artemis I, human beings will fly around the Moon on Artemis II.
This video takes the viewer on a journey to the 34th anniversary image of the launch of the legendary NASA/ESA Hubble Space Telescope: the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651). The object is located 3400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favourite target of amateur astronomers.

#ad #stiinta #fizica #science #tehnologie #technology #cristianpresura algoritm:”Susținătorii teoriei Pământului plat prezintă o viziune radical diferită asupra formei planetei noastre, afirmând că Pământul este plat, asemănându-se cu o pășune cu Polul Nord în centrul său, iar marginile exterioare sunt înconjurare de un zid de gheață arctică. Această afirmație contrastează puternic cu înțelegerea științifică larg acceptată că Pământul este un corp sferic. Această neînțelegere se extinde la credința lor că dincolo de zidul de gheață se află teritorii necunoscute, deși expediții istorice precum cea transatlantică din 1955 au traversat Antarctica, trecând prin Polul Sud și demonstrând accesibilitatea acestui continent.
Susținătorii teoriei Pământului plat cred și că Luna și Soarele se mișcă deasupra Pământului plat, la câteva mii de kilometri deasupra, în contradicție cu distanța recunoscută științific de 150 de milioane de kilometri până la Soare. Ei susțin că mișcarea Soarelui determină ziua și noaptea, ignorând faptul că rotația Pământului sferic în jurul axei sale este responsabilă pentru alternanța dintre zi și noapte.
Un alt element al teoriei lor este că Pământul plat este acoperit de un dom înalt de câteva sute de kilometri, un dom pe care nimeni nu l-a atins, în ciuda faptului că sateliții sunt lansați regulat la altitudini mult mai mari, fără să întâmpine niciun obstacol fizic. Ei mai cred că aproape de partea superioară a domului există o masă gelatinoasă, similară piftiei, în timp ce în realitate, atmosfera se rarefiază pe măsură ce altitudinea crește, fără a exista vreo substanță de această natură.
Despre stele, susținătorii teoriei afirmă că sunt simple lumini pe cer și că gravitația nu există, în timp ce știința modernă demonstrează că stelele sunt sori îndepărtați și că gravitația este forța care guvernează mișcările orbitale ale planetelor. Ei contestă autenticitatea fotografiilor spațiale furnizate de NASA, susținând că sunt falsificate și înlocuindu-le cu ilustrații generate pe calculator.
În plus, susținătorii teoriei Pământului plat nu pot explica fenomene observabile cum ar fi durata diferită a zilei între emisfere, vizibilitatea diferită a constelațiilor sau comportamentul corpurilor ceresti la răsărit și la apus, care sunt consistente cu un Pământ sferic.
Astfel, teoria Pământului plat rămâne profund în contradicție cu dovezi științifice bine stabilite și observații repetate, care confirmă fără îndoială sfericitatea Pământului. Această teorie este mai mult un exercițiu de gândire critică și scepticism decât o ipoteză susținută de dovezi empirice. În concluzie, Pământul nu este plat; el este demonstrabil și vizibil o sferă.”
