Artemis II will make history, taking astronauts around the moon for the first time in more than 50 years. The four-person crew will launch from NASA’s Kennedy Space Center on Merritt Island, Florida, for a 10-day journey.
The trip will pave the way for future Artemis missions intended to eventually see astronauts set foot on the moon, and the building of a permanent lunar base.
Read more here about what you need to know regarding the Artemis II mission, including how long it will take, who the astronauts are and how to watch.

Artemis II Moon Rocket Launch LIVE: NASA’s Artemis II Live Views from Kennedy Space Center, FL | CNBC TV18 LIVE feed from Kennedy Space Center in Florida will provide continuous views of the Artemis II Moon rocket beginning on Thursday, March 19, with rollout from the Vehicle Assembly Building to Launch Pad 39B. NASA Sends Astronauts around the Moon for the first time in 50 years. Live view of the Artemis II Moon rocket. While the Artemis II launch window opens as early as Wednesday, April 1, the mission management team will assess flight readiness across the spacecraft, launch infrastructure, and the crew and operations teams before selecting a launch date. NASA’s Artemis II mission is scheduled to lift off from Kennedy Space Center on April 1. The two-hour launch window starts at 6:24 p.m. EDT (2224 UTC). Four astronauts — three from NASA and one from the CSA (Canadian Space Agency) — make up the Artemis II crew: NASA astronaut Reid Wiseman, Artemis II commander. NASA astronaut Victor Glover, Artemis II pilot. NASA astronaut Christina Koch, Artemis II mission specialist. Canadian Space Agency (CSA) astronaut Jeremy Hansen, Artemis II mission specialist. After launching into space atop NASA’s Space Launch System (SLS) rocket, the crew will journey around the Moon and back in their Orion spacecraft, named Integrity, on an approximately 10-day mission. Artemis II will be the first crewed flight test of SLS and Orion, testing the technologies we’ll need for long-term lunar exploration and human missions to Mars. #nasa #artemislaunch #artemis2 #nasaastronauts #rocketlaunch #cnbctv18 #livestream.

Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have come from the outer solar system, i.e., beyond Jupiter. For a long time, material from the outer solar system was considered necessary to bring volatile components such as water to Earth. Accordingly, there must also have been an exchange of material between the outer and inner solar systems during the formation of Earth. But is that really true?
Planetary scientists Paolo Sossi and Dan Bower, from ETH Zurich, compared existing data on the isotopic ratios of a wide range of meteorites, including those from Mars and the asteroid Vesta, with those of Earth. Isotopes are sibling atoms of the same element (same number of protons) that have a different mass (different number of neutrons).
The researchers analyzed this data in a new way and arrived at a surprising conclusion: the material that makes up Earth originates entirely from the inner region of the solar system.
Researchers at the National Institute of Standards and Technology (NIST) have developed a new way to package photonic integrated circuits—tiny chips that convey information using light instead of electricity—so they can survive and operate in extreme environments, from scorchingly hot industrial settings to ultracold vacuum chambers and the depths of outer space.
“Our study marks a major step toward bringing the speed and efficiency of photonics into environments where conventional semiconductor chips powered by electric current and photonics chips packaged using traditional methods have not been able to operate,” said NIST physicist Nikolai Klimov, who led the project. The results were just published in Photonics Research.
How can scientists determine if exoplanets orbiting M-dwarf stars are habitable? This is what a study recently presented at the 247th Meeting of the American Astronomical Society hopes to address as a team of scientists investigated how stellar activity from M-dwarf stars could influence planetary habitability. This study has the potential to help scientists to narrow constraints for conditions regarding finding life beyond Earth.
For the study, the researchers explored a unique type of M-dwarf star called a complex periodic variable (CPV), which are young M-dwarf stars that have been observed to have periodic decreases in brightness. While brightness dimming is often attributed to a planet passing in front of the star, or even gas and dust, astronomers were perplexed regarding this particular phenomenon. Their initial hypothesis was the brightness dips resulted from bright and dark regions on the star’s surface.
After significant analysis, the researchers discovered that the brightness dips were caused by a “donut” of super-heated gas called plasma, which all stars are made of, trapped within the star’s magnetic field. As the donut rotated around the star, it caused periodic dips in brightness. Along with estimating that approximately 10 percent of M-dwarf stars could be designated as CPVs, they also note this unique stellar could help gain greater insight into how it influences planetary conditions, which the researchers dubbed “space weather stations”
