Space and astronomy news
The James Webb Space Telescope has observed a huge water vapor plume emanating from Saturn’s moon Enceladus. Astronomers say the plume reaches nearly 10,000 kilometers (6,200 miles) into space, which is about the equivalent distance as going from Ireland to Japan. This is the largest plume ever detected at Enceladus.

If you’ve ever played Kerbal Space Program, you know how difficult it can be to get your spacecraft into the orbit you want. It’s even more difficult in real life. This is why it’s pretty impressive to see a proposal to study all of Saturn’s large inner moons in one go.

Enigmatic North Korea may attempt to put a satellite in orbit, as early as this week.
Update: May 31st – Alas, it was not meant to be. While North Korea’s latest satellite launched last night on the first day of the launch window at 21:29 Universal Time (UT), the rocket seems to have experienced an anomaly on the second stage, and the now posthumously named ‘Cheollima-1’ rocket with the ‘Malligyong-1’ (‘grand view’ (?) in Korean) satellite splashed down in the Sea of Korea. This trajectory would seem to indicate that the mission was indeed aiming for a sun-synchronous orbit.
Satellite spotters worldwide may have a new clandestine target to hunt for in orbit soon. The North Korean government announced possible plans this week to field another satellite into orbit by mid-June. This comes after a public visit by leader Kim Jong Un and his daughter Kim Ju-Ae to a DPRK National Aerospace Development Administration (NADA) aerospace facility earlier this month. Kim “approved the future action plan of the preparatory committee,” according the Korean Central News Agency, and said that the satellite was “an urgent requirement of the prevailing security environment of the country.”

As NASA prepares to return astronauts to the Moon with Artemis III, China is ramping up its efforts for a crewed lunar landing, targeting earlier than 2030. Lin Xiqiang, the deputy director of China’s Manned Space Agency announced that the Chinese Lunar Exploration Program (CLEP) is preparing for a “short stay on the lunar surface and human-robotic joint exploration.”

As Artemis II gets ready to launch in November 2024, NASA recently announced it is pursuing contract proposals from private companies for the development of a next-generation Lunar Terrain Vehicle (LTV) to be used for crewed missions starting with Artemis V, which is currently scheduled for 2029. NASA has set a due date for the proposals of July 10, 2023, at 1:30pm Central Time, with the announcement for rewarded contracts to occur in November 2023.

Launched on April 14, 2023, the European Space Agency’s (ESA) Jupiter Icy Moons Explorer (Juice; formerly known as JUICE) spacecraft has finally completed the unfurling of its solar panel arrays and plethora of booms, probes, and antennae while en route to the solar system’s largest planet.

In a recent study published in National Science Review, a team of researchers led by the China University of Geosciences discuss direct evidence of an ancient ocean and its shoreline that existed in the northern hemisphere of Mars during the Hesperian Period, or more than 3 billion years ago. This finding is based on data collected by the China National Space Agency’s (CNSA) Zhurong rover in the Vastitas Borealis Formation (VBF), which lies within southern Utopia Planitia on Mars.

When two black holes collide, they don’t smash into each other the way two stars might. A black hole is an intensely curved region of space that can be described by only its mass, rotation, and electric charge, so two black holes release violent gravitational ripples as merge into a single black hole. The new black hole continues to emit gravitational waves until it settles down into a simple rotating black hole. That settling down period is known as the ring down, and its pattern holds clues to some of the deepest mysteries of gravitational physics.

NASA makes successful rover missions seem mundane. Spirit and Opportunity were wildly successful, and Curiosity and Perseverance would both be considered successes even if they stopped working today. But complex missions don’t succeed without rigorous testing.
The ESA takes that lesson to heart, and when it comes to their Mars rover, they’ve built a ‘rover playground’ to test it in.

The European Space Agency’s latest third generation Meteosat-I 1 weather satellite shows its stuff, with more to come.
You’ve never seen the Earth and its complex weather systems like this. The European Space Agency (ESA) recently unveiled views from their latest weather satellite in geostationary (GEO) orbit, Meteosat Third Generation Imager-1 (MTG-I 1).
