Artemis 2 astronauts saw Earth slip from view during their lunar flyby on Flight Day 6.

Still aglow from their triumphant lunar flyby, the Artemis II astronauts put in a call to their friends aboard the International Space Station on Tuesday as they headed home from the moon. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space. "We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

Life in space is weirder than you might think, with the crew facing toilet issues, saliva collections, DIY fixes to onboard components and a menu of dehydrated food.

On Truwana/Cape Barren Island off the northeast coast of Tasmania, several rarely seen animals were captured on camera for the first time. The images were taken as part of a camera survey led by indigenous Truwana Rangers, and supported by WWF-Australia’s Eyes on Country Program and Dr. Elizabeth Znidersic from Charles Sturt University.

Over seven hours, the astronauts took thousands of photos that will help inform scientists’ understanding of the moon. The first ones have now been released.

For the first time ever, humans have glimpsed the entire far side of the moon with their own eyes — and their photos are beginning to come in

You've probably heard it by now: NASA’s Artemis 2 mission was the first to launch astronauts to fly by the moon in more than 50 years. But that was just the first of the firsts for this mission.

NASA's Artemis 2 astronauts viewed parts of the moon never before seen with human eyes during their epic lunar flyby today (April 6) —and set a spaceflight record in the process.

As they broke the record for farthest distance from Earth ever traveled by an astronaut, NASA's Artemis 2 crew took a moment to dedicate a few features on the moon's surface for their spacecraft and lost loved ones.

NASA's Artemis 2 astronauts have now traveled farther from Earth than any people in history, breaking the mark set by the Apollo 13 crew in April 1970.

The four astronauts aboard the Orion spacecraft have surpassed the mark set by Apollo 13 in 1970.

Not all spider venoms are created equal. Some are harmless to people, while others can be quite dangerous.

Uri Alon was long puzzled by a textbook statistic: Longevity, the thinking went, was about 20 percent in our genes. “That makes you think what’s the rest of the 80 percent: Is it the lifestyle? Why should we study genes for lifespan if it’s not that important? It kind of bothered me,” said Alon, a physicist turned systems biologist at the Weizmann Institute of Science in Israel. Alon us

The Artemis 2 astronauts might be the first humans to survey certain areas of the moon's far side, and they're chronicling their historic journey in detail.

By Joey Roulette HOUSTON, Texas April 6 (Reuters) - The four astronauts of NASA's Artemis II mission reached the furthest point that any human has been from Earth on Monday, cruising along a path in

The Orion's four crew members have surpassed the mark previously set by Apollo 13 in 1970.

During the seven-hour trip around the moon, the Orion's four crew members will surpass the record for the farthest distance from Earth traveled by humans.

The four astronauts of NASA's Artemis 2 mission have arrived at the moon. They entered the lunar sphere of influence early Monday morning (April 6).

NASA's Artemis 2 astronauts will make a historic moon flyby today (April 6). Here's how it will happen, hour by hour.

The distance Orion will travel during the Artemis II moon flyby will let the crew see the entire lunar disk, including features Apollo astronauts didn’t observe.

With the moon looming ever larger, the Artemis II astronauts raced to set a new distance record Monday from Earth on a lunar fly-around promising magnificent views of the far side never seen before by eye. The six-hour flyby is the highlight of NASA's first return to the moon since the Apollo era with three Americans and one Canadian — a step toward landing boot prints near the moon's south pole in just two years. A prize — and bragging rights — awaits Artemis II.

The crew’s Orion capsule entered what’s known as the lunar sphere of influence at around 12:41 a.m. ET Monday, crossing into the region of space where the moon’s gravitational pull is stronger than the pull of Earth’s.

The four Artemis 2 astronauts had a chance to observe the moon this weekend, and to say they were thrilled may be an understatement of cosmic proportions.

The four Artemis 2 astronauts will see a solar eclipse from beyond the moon's far side on Monday evening (April 6), and they'll use the opportunity to make some science observations.

The NASA astronauts also sent down Easter messages Sunday while gearing up for a historic pass behind the moon Monday.

This offers us a glimpse of the discovery surge scientists expect to occur once full operations begin.
