Hope for present-day Martian groundwater dries up
Tuesday, 25 January 2022 06:43
Liquid water previously detected under Mars' ice-covered south pole is probably just a dusty mirage, according to a new study of the red planet led by researchers at The University of Texas at Austin.
Scientists in 2018 had thought they were looking at liquid water when they saw bright radar reflections under the polar cap. However, the new study published Jan. 24 in the journal Geophysica Chinese lunar rover's 2-year travelogue on moon's far side reported

Chinese scientists published the country's lunar rover travelogue of its first two years of service that depicted the unique and untrodden moonscape on the moon's far side, revealing its notable differences with the near side with in situ evidence.
The study published on Thursday in the peer-reviewed journal, Science Robotics, described cloddy soil, gel-like rocks, and fresh small craters How to Retain a Core

Have you ever wondered how a coring bit grabs and holds onto a rock core?
As we drill, the bit teeth cut a 27mm diameter circle in the rock and leave the 13mm diameter center intact. As we dig deeper, that cylinder of rock is fed into the sample tube that was loaded inside the bit. When the drill reaches its target depth, typically 66mm, the core is fully in Looking Up at the Asteroids in the Neighborhood

Asteroids fly through our solar system all the time, but it's rare for us to take notice of them. But that's changed this week, as an asteroid passes within 1,231,184 miles of Earth on January 18. The asteroid, dubbed 7482 (1994 PC1), was first seen in 1994 and is about two-thirds of a mile wide.

At 2 pm EST Monday, Webb fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final postlaunch course correction to Webb's trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1 million miles away from the Earth.
The final mid-course burn added only about 3.6 miles per hour (1 Webb telescope reaches final destination, a million miles from Earth

The James Webb Space Telescope has arrived at its cosmic parking spot a million miles away, bringing it a step closer to its mission to unravel the mysteries of the Universe, NASA said Monday.
At around 2:00 pm Eastern Time (1900 GMT), the observatory fired its thrusters for five minutes to reach the so-called second Lagrange point, or L2, where it will have access to nearly half the sky at OneWeb and Hughes to bring orbital broadband service to India

A SpaceX Dragon capsule that had transported supplies and experiments to the International Space Station splashed down along the coast of Florida on Monday afternoon.
The capsule's four main parachutes were deployed shortly after 4 p.m. EST, and splashdown was confirmed two minutes later, the company said.
The freighter delivered some 4,900 pounds of science experiments and stati Sols 3362-3363: Sedimentologist's Delight

After a few sols of challenges that prevented us from getting close-up MAHLI imaging of this dark outcrop in front of us, today we were finally able to plan the contact science that we were hoping for.
Yesterday there was a small rock under the right rear rover wheel, so we had to kick that rock to the curb to get into a stable position for using the rover arm. This morning's downlink data Japan’s H3 rocket further delayed by engine woes

After spending most of 2020 and all of 2021 struggling with the expendable H3’s novel LE-9 main engine, officials with the Japan Aerospace Exploration Agency (JAXA) told reporters last week that the H3 will not be ready to launch by the end of March as previously hoped.
