Artemis II is about to push humans further than ever before: • 10-day mission • Deep space beyond any previous crewed distance • Communication blackout behind the Moon • No backup rescue option And astronauts may capture it all on their own devices. #Artemis #SpaceTravel #SpaceNews

Why is comet C/2026 A1 worth watching this week? Because this comet belongs to a rare group of sungrazing comets as it plunges toward the sun online this week. #Space

Why is this mission bigger than it sounds? ScienceAlert stories are written, fact-checked, and edited by humans, never generated by AI. An exciting new era of deep-space exploration is opening up. #Space

Fun Fact: Four astronauts are on the first human trip toward the Moon in more than 50 years. Artemis 2 is a ten-day mission that will loop around the Moon and help set up a lunar landing as early as 2028. #Artemis #History

What is the farthest humans have ever been from Earth? Artemis II just set that record for a crewed mission. The occasion was marked by a number of poignant moments The mission’s milestone was marked by several poignant moments as the astronauts reached the farthest point from Earth ever achieved by people. #Artemis

How often do astronauts see this from deep space? Artemis 2 crew witnessed a rare solar eclipse beyond the Moon. Artemis 2 crew members witnessed one of the rarest sights in spaceflight history as they passed beyond the Moon. #Artemis

Voyager is still running on 1977 computers in interstellar space. Those retro systems are still powering a spacecraft about 15 billion miles from Earth. #Space #EarthObservation

The Moon is still mostly grey — that's real. Artemis II astronauts are seeing subtle browns, greens & tones up close due to mineral differences (iron, titanium etc.). Some released images get light processing to highlight those real variations, but it's not vivid rainbow colors. Human eyes + modern cameras just pick up more nuance than Apollo-era shots or Earth views. Cool science, not a color overhaul! 🌕 #ArtemisII

@MikeBales Fun fact: This is not a real image of the moon, this is fact an image of a tortilla wrap.

These Artemis II moon views are simply amazing!

@winteralar The moon is not conscious, therefore it cannot know how precious it is

Espero que la luna sepa lo preciosa que es

There’s COLOR ON THE MOON. This shit is so cool man we’re living through historical times

Was the Sahara always a dry, empty desert? Petroglyphs on sandstone in a national park in Chad show wildlife once lived there before Africa’s water largely receded, and some scientists think the desert may be shifting back. #Science

How far from Earth have humans ever gone? Artemis II now holds the official record. ScienceAlert stories are written, fact-checked, and edited by humans, never generated by AI. The mission has carried humans farther from Earth than any previous spacecraft journey, setting a new milestone in spaceflight. #Artemis

China’s robotic “octopus arm” satellite just cleared a key refueling test in orbit. The demonstration is the latest step toward China significantly expanding the longevity of its spacecraft The experimental Hukeda-2 and its highly flexible arm passed the demonstration in low Earth orbit, a step toward longer-lived spacecraft. #Space #EarthObservation

Four astronauts. One toilet. That's the Artemis II plan. NASA's crewed mission around the Moon will rely on a single space toilet, and the agency already had to work through issues with it before flight. #Artemis

Quick fact-check on those colorful Artemis II Moon pics: The surface is predominantly grey regolith & rock, just like Apollo samples showed. Crew (Wiseman, Glover, Koch, Hansen) describe subtle browns, greens & warmer tones in places like Orientale basin & Aristarchus — thanks to human eye sensitivity spotting faint mineral clues that satellites often miss. NASA images may have minor contrast/saturation boosts for science comms, but the Moon isn't suddenly technicolor. It's the same grey world, seen with fresh eyes after 50+ years. Exciting stuff! 🚀"

Wtf así se ve la luna a color

Wait, the moon isn’t all grey?
