The lander and rover of the Chang'e 4 probe have resumed work for a 29th lunar day on the far side of the moon.
The lander woke up at 9:43 pm Tuesday (Beijing Time), and the rover, Yutu-2 (Jade Rabbit-2), awoke at 3:54 am Tuesday, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

Why do asteroids in the solar system have the sizes we observe? Two researchers at the Max Planck Institute for Astronomy have found an answer to that fundamental question: For the birth planets and planet precursors in our solar system 4.5 billion years ago, turbulence played a key role, helping to bring together pebble-like objects to form larger aggregations known as planetesimals.

Using data from NASA's Spitzer Space Telescope, scientists have identified the three fastest-spinning brown dwarfs ever found. More massive than most planets but not quite heavy enough to ignite like stars, brown dwarfs are cosmic in-betweeners. And though they aren't as well known as stars and planets to most people, they are thought to number in the billions in our galaxy.
In a study app First transiting exoplanet's 'chemical fingerprint' reveals its distant birthplace

Astronomers have found evidence that the first exoplanet that was identified transiting its star could have migrated to a close orbit with its star from its original birthplace further away. Analysis of the planet's atmosphere by a team including University of Warwick scientists has identified the chemical fingerprint of a planet that formed much further away from its sun than it currently resid SKF bearings help Mars Rover collect rock and regolith samples on the planet's surface

Bruno: The next big thing for ULA is a long-endurance upper stage

WASHINGTON — When United Launch Alliance started to develop its new Vulcan rocket, it envisioned using a new upper stage called ACES, short for advanced cryogenic evolved stage. ULA’s president and CEO Tory Bruno described it in 2018 as a transportation system that would operate in space for weeks or months performing missions in different orbits.

Long before NASA's Perseverance rover touched down on the Red Planet on Feb. 18, one of its highest-level mission goals was already established: to seek out signs of ancient life on the Martian surface.
NASA's Webb Telescope packs its sunshield for a million mile trip
Tuesday, 06 April 2021 18:52 Write a comment
Engineers working on NASA's James Webb Space Telescope have successfully folded and packed its sunshield for its upcoming million-mile (roughly 1.5 million kilometer) journey, which begins later this year.
The sunshield—a five-layer, diamond-shaped structure the size of a tennis court—was specially engineered to fold up around the two sides of the telescope and fit within the confines of its launch vehicle, the Ariane 5 rocket. Now that folding has been completed at Northrop Grumman in Redondo Beach, California, the sunshield will remain in this compact form through launch and the first few days the observatory will spend in space.
Designed to protect the telescope's optics from any heat sources that could interfere with its sight, the sunshield is one of Webb's most critical and complex components.

The triumphant landing of the Perseverance rover has inspired all Americans, and indeed much of the world. President Biden should follow it up by launching the program to send humans to Mars.
While robotic rovers are wonderful, they cannot resolve the fundamental scientific questions that Mars poses to humanity, which relate to the potential prevalence and diversity of life in the universe.
