Poprvé od Apolla se astronauti chystají nacvičit přistání na Měsíci – bez opuštění lunární oběžné dráhy
Artemis III má posádku. Devátého června NASA oznámila čtyři členy příští mise programu Artemis, jejíž start se očekává nejdříve v červnu 2027: velitele Randyho Bresnika, letové specialisty Andreho Douglase a Franka Rubia a pilota Lucu Parmitana, Itala z Evropské kosmické agentury. NASA vybrala i náhradníka, Boba Hinese. Na rozdíl od posádky mise Artemis II, která absolvovala cestu kolem Měsíce dlouhou 406 757 kilometrů, se tahle mise odehraje mnohem blíž domovu.
Artemis III: la NASA annuncia gli astronauti della missione. E c’è anche Luca Parmitano
I quattro astronauti, tra cui l’italiano Parmitano che sarà pilota della missione, tenteranno di agganciarsi a due diversi moduli lunari in orbita terrestre, aprendo la strada a un futuro allunaggio. DI Swapna Krishna pubblicato 10-06-2026 L'equipaggio di Artemis III posa per una foto ufficiale.

NASA announces the astronauts for the next Artemis mission. Here's what they'll be doing. Original
Artemis III has a crew. On June 9, NASA announced the four crewmembers of the next Artemis mission, expected to launch no earlier than June 2027: Commander Randy Bresnik, and Mission Specialists Andre Douglas and Frank Rubio, and Pilot Luca Parmitano, an Italian with the European Space Agency. NASA also selected a backup crew member, Bob Hines. Unlike the crew of Artemis II, which took a 252,756-mile ride around the moon, this crew’s mission will be a lot closer to home.
Tepelný štít Artemis II vzbudil vážné pochyby. Přesto NASA věří, že posádka bude v bezpečí
Čtyřicet tisíc kilometrů za hodinu. Teploty přes 2 760 °C. Až se Artemis II bude řítit zpět na Zemi, bude jedinou překážkou mezi posádkou a smrtícím žárem jediná vrstva materiálu silná několik centimetrů – tepelný štít Orionu. NASA buduje záložní systémy do všeho. Téměř vždy existuje náhradní řešení, druhá možnost, nouzový plán. U tepelného štítu záloha neexistuje. Jednoduše musí fungovat. Jenže bude fungovat? NASA se domnívá, že odpověď je „ano".
Artemis II's last test: Will its heat shield work? Original
When Artemis II comes blazing back through the Earth’s atmosphere, it will be traveling at around 25,000 miles per hour and reach temperatures up to 5,000 degrees Fahrenheit. The only thing protecting the crew from the fires of re-entry? Orion’s heat shield. NASA builds redundancy into everything. There’s almost always a backup system or a secondary option in case something goes wrong. But there is no redundancy for the heat shield. It simply has to work. But will it?
Las épicas fotos de Artemis II muestran la Tierra, la Luna y las estrellas como nunca antes las habías visto
El lunes, los astronautas Reid Wiseman, Victor Glover, Christina Koch y Jeremy Hansen se convirtieron en los primeros seres humanos en más de 50 años en ver el lado oculto de la Luna. Artemis II despegó a las 6:35 p.m. ET del miércoles 1 de abril. La misión de 10 días consiste en una trayectoria en honda alrededor de la Luna, allanando el camino para un alunizaje con Artemis IV en 2027. (Artemis III, programada para 2026, probará los sistemas necesarios para alunizar humanos al año siguiente).

Glorious Artemis II photos show the Earth, moon, and stars like you’ve never seen them before
Yesterday, astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen became the first humans in over 50 years to see the far side of the moon. Artemis II launched at 6:35 p.m. ET on Wednesday, April 1. The 10-day mission is a slingshot around the moon, paving the way for a moon landing with Artemis IV in 2027.

Artemis II má 45 minut na to, aby znovu vyfotografovala Zemi z orbity Měsíce
Štědrý den roku 1968. Frank Borman, Jim Lovell a William Anders se právě stali prvními lidmi na oběžné dráze Měsíce — průkopníky mise, která připravila půdu pro historické přistání o rok později. Když se podívali z oken velitelského modulu Apollo 8, zahlédli modrou planetu, kterou zanechali za sebou — domov každého tehdy žijícího člověka. „Páni, to je ale krásné!" řekl Anders, když popadl upravený fotoaparát Hasselblad 500EL a vyfotil ikonický snímek, dnes známý jako Earthrise — Východ Země.
How Artemis II astronauts plan to capture a new ‘Earthrise’ Original
On December 24, 1968, Frank Borman, Jim Lovell, and William Anders became the first humans to enter orbit around the moon, on a mission that set the stage for America’s historic moon landing the next year. As they looked out the windows of their Apollo 8 command module, they glimpsed the blue planet they’d left behind, home to every human in existence. “Wow, is that pretty!” Anders said, grabbing a modified Hasselblad 500EL camera to snap the iconic photo now called Earthrise.

„Jsme 66 830 kilometrů od Měsíce," říká astronaut Reid Wiseman, velitel mise Artemis II – nadcházejícího letu NASA, jenž vrátí lidi na oběžnou dráhu Měsíce. Na Wisemana a jeho kolegy doléhá obrovská odpovědnost. Připravují půdu pro přistání astronautů na měsíčním povrchu poprvé za více než 50 let. Wisemanova slova ale nezní nijak napjatě. Hlas je klidný, uvolněný, na sobě modrý svetr s nápisem „ARTEMIS" na prsou.
NASA's Artemis II ushers in a new era of human exploration

火星の謎に迫る岩石サンプル6選 NASAの無人探査車が採取
NASAの火星探査車「パーシビアランス」は2021年から火星の上を動き回り、岩石の収集を続けてきた。いずれはこうして集められた岩石によって、火星の歴史、火星と地球との違い、そして生命の起源についての理解が塗り替えられる日が来るかもしれない。「この探査車に積まれたサンプルの一つひとつが、火星に関する極めて重要な問いへの答えを持っている可能性があります」と、米アリゾナ州立大学の惑星科学者ミーナクシ・ワドワ氏は言う。 「火星サンプルリターン（MSR）」と名付けられたこのミッションにおいて、ワドワ氏は主任科学者として、これらの岩石を1億キロ以上離れた地球に輸送する計画の立案に携わっている。（参考記事：「解説：小惑星ベンヌからのサンプルリターンに成功、NASA探査機」） 火星で集められたサンプルには、それがどれくらい古いものか、また「火星の古代環境についての重要な情報」が記録されている可能性があると、米カリフォルニア工科大学の地球化学者で、パーシビアランス計画の副主任科学者を務めるケン・ファーリー氏は説明する。...
Here's the best time to catch a glimpse of April 2025's spectacular show
The Lyrid meteor shower is one of the most well-known stellar displays, occurring once a year in April. It's also one of the oldest meteor showers that we know of, with records dating back to 687 BCE from Chinese astronomers. Unlike many meteor showers, the Lyrids are relatively short: In 2025, the event runs a little more than a week, from April 17 to April 26. It will peak in the nighttime hours of April 21 to 22.
Are we alone in the universe? These Mars rocks could finally give us an answer.
Across the Martian landscape, the view is breathtaking. Everything is quiet, except for a little robot patiently trundling up the sides of Jezero Crater. Perseverance, affectionately known as “Percy,” doesn’t have the ability to appreciate the reddish-orange hues of the desert landscape like a human can.

Today's the day: A solar eclipse will darken the skies in the northeastern US and Canada in the early hours of Saturday. Unlike the “Great American Eclipse” of 2024, however, this will not be a total eclipse. Instead, this event will be a partial eclipse visible in parts of the northern hemisphere. While this one will lack the dramatic "totality" of the 2024 event, a partial eclipse is still worth seeing.

Partial Solar Eclipse: Where and when to see the sunrise event on March 29 Original
On Saturday, March 29, a solar eclipse will darken the skies. Unlike the “Great American Eclipse” of 2024, though, this will not be a total eclipse; instead, a partial eclipse will be visible in the early morning hours in parts of the northern hemisphere. A partial eclipse isn’t as dramatic as a total eclipse, but it’s still worth seeing. While the sun will not be fully obscured, with proper eye protection, you will be able to see the moon take a bite out of the sun.
