Future of Earth's defense is ground-based planetary radar
Powerful radar systems have played a major role in the study of planets, moons, asteroids, and other objects in our Solar System for several decades, and now have a "unique role" to play in planetary defense - "providing protection to the nations of the world from devastating asteroid and comet impacts," according to the newly released Planetary Science and Astrobiology Decadal Survey 2023-2032.                Two largest Marsquakes to date recorded from planet's far side
The seismometer placed on Mars by NASA's InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. The pair are the first recorded events to occur on the planet's far side from the lander and are five times stronger than the previous largest event recorded. 
Seismic wave data from the events could help researchers learn more about the                Nation mulls mission on far side of moon
Chinese scientists and engineers are considering sending a robotic probe to collect dust and rocks from the far side of the moon, an ambitious endeavor that would likely be a world first, according to a senior space agency official. 
Wu Yanhua, deputy director of the China National Space Administration, said the United States, Russia and China have brought lunar substances back to Earth, bu                Rad Rock Rumblings Sols 3453-3555
Entering the weekend, we have a few more 'rad' rocks we'd like to get some science on before we drive farther away from the Greenheugh pediment and begin our journey again up Mt. Sharp. 
Starting on sol 3453, we break out our arm instruments for contact science with APXS and MAHLI on "Rumblings," a rock with an interesting knobby texture, followed by a delta over to "Delting," a flat area o                Artemis I, Crew-4, and Starlink Rockets on the Pad

QPS-SAR-3 and QPS-SAR-4 are under manufacturing by iQPS with more than 25 partner companies in northern Kyushu and other parts of Japan. Tw                NASA extends exploration for 8 planetary science missions
Following a thorough evaluation, NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge and understanding of the solar system and beyond.

 After nearly a week of delays, the first-ever all private astronaut mission to the International Space Station came to an end Monday, with the crew splashing down in the early afternoon off the coast of Florida. 
 "Dragon Endeavour has returned, bringing the Axiom-1 crew home," SpaceX officials announced on the livestream. "On behalf of the entire SpaceX team, welcome back to planet Earth                Rich trio back on Earth after charter trip to space station

Three rich businessmen returned from the International Space Station with their astronaut escort Monday, wrapping up a pricey trip that marked NASA's debut as a B&B host.
Crew-4 astronauts head to space station to conduct microgravity science

NASA's SpaceX Crew-4 mission, originally scheduled to launch to the International Space Station on Saturday, April 23, from NASA's Kennedy Space Center in Florida, has been rescheduled to Wednesday, April 27. This launch carries three NASA astronauts—Kjell Lindgren, Robert Hines, and Jessica Watkins—and ESA (European Space Agency) astronaut Samantha Cristoforetti. This spaceflight is the first for Hines and Watkins and the second for Lindgren and Cristoforetti. 
Here are details on some of the research riding with the crew aboard the SpaceX Dragon Freedom capsule into low-Earth orbit:
Replacement retinas
Artificial retinas could restore meaningful vision for the millions of people on Earth who suffer from retinal degenerative diseases, including retinitis pigmentosa and age-related macular degeneration. The ISS National Lab-sponsored study Protein-Based Artificial Retina Manufacturing evaluates a manufacturing process to develop artificial human retinas using a light-activated protein called bacteriorhodopsin, which could replace the function of damaged light-sensing cells in the eye.
