Unraveling river pathways on Earth and Mars
Sunday, 06 August 2023 01:08
In a groundbreaking analysis, scientists from Tulane University have delved deep into the winding paths of rivers on both Earth and Mars. This study, recently published in Nature Geosciences, aims to understand how climate change influences the shifting paths of these meandering rivers.

On Aug. 5, NASA's Curiosity rover will notch its 11th year on Mars by doing what it does best: studying the Red Planet's surface. The intrepid bot recently investigated a location nicknamed "Jau" that is pockmarked with dozens of impact craters. Scientists have rarely gotten a close-up view of so many Martian craters in one place. The largest is estimated to be at least as long as a basketball c Can we see Mars' Breath in the Winter Cold: Sols 3907-3908

Earth planning date: Wednesday, August 2, 2023: We don't have a lot of power to play with today, so we have to be careful about how much time we give the different activities. As Arm Rover Planner, I got to sequence the contact science activities today.
We start this two-sol plan with a nap to save up power. After waking up in the afternoon, we do a short block of imaging. Mastcam is takin Daily records of atmospheric temperature with Perseverance

Atmospheric temperature is a meteorological variable of daily concern to humans. Temperature also has a major impact on Perseverance mission operations (e.g. temperature sensors are distributed throughout the rover to monitor its thermal performance). In addition, temperature data are key to the mission's scientific investigations of the atmosphere.

NASA's LunaH-Map (Lunar Polar Hydrogen Mapper) mission, a briefcase-sized lunar orbiter that launched as a ride share on NASA's Artemis I mission last year, has ceased operations after successfully demonstrating its neutron spectrometer can detect water and ice at the lunar surface.
The LunaH-Map CubeSat was designed to map ice deposits across the Moon's South Pole as part of NASA's SIMPLE New exoplanet discovery builds better understanding of planet formation

An international team of scientists have discovered an unusual Jupiter-sized planet orbiting a low-mass star called TOI-4860, located in the Corvus constellation.
The newly discovered gas giant, named TOI-4860 b, is an unusual planet for two reasons: stars of such low mass are not expected to host planets like Jupiter, and the planet appears to be particularly enriched by heavy elements.

Sometimes, the best place to hide a secret is in broad daylight. Just ask the sun.
"The sun is more surprising than we knew," said Mehr Un Nisa, a postdoctoral research associate at Michigan State University. "We thought we had this star figured out, but that's not the case."
Nisa, who will soon be joining MSU's faculty, is the corresponding author of a new paper in the journal Physi Webb Telescope unmasks Ring Nebula's cosmic dance

NASA's James Webb Space Telescope (JWST) has released exquisite new visuals of the famed Ring Nebula, or Messier 57, to the world. The unveiling was done by a global consortium of astronomers, a team steered by Professor Mike Barlow of UCL, UK, Dr Nick Cox of ACRI-ST, France, and with contributions from Professor Albert Zijlstra of The University of Manchester.

The 117th and final launch of Europe’s Ariane 5 rocket capped a series which began in 1996. Commercial, institutional and scientific payloads included such iconic missions as Rosetta, the James Webb Space Telescope and Juice. Seen here is the launch campaign for VA261 on 5 July 2023, to close the Ariane 5 book; onboard were German aerospace agency DLR’s Heinrich Hertz experimental communications satellite and French communications satellite Syracuse 4b.
First test images from Euclid space telescope unveiled
Saturday, 05 August 2023 11:10
The Euclid space telescope, launched July 1 on a mission to shed more light on elusive dark matter and dark energy, has reached its destination orbit and on Monday its European operators revealed its first test images.
The star-filled snapshots were taken during the space telescope's commissioning—a phase during which its powerful instruments are finely calibrated—and therefore not representative of its full potential.
But the European Space Agency (ESA) says the tests already show it will be capable of fulfilling its massive mission.
"After more than 11 years of designing and developing Euclid, it's exhilarating and enormously emotional to see these first images," Euclid project manager Giuseppe Racca in a statement.

NASA back in touch with Voyager 2 after 'interstellar shout'
Friday, 04 August 2023 21:19
NASA has succeeded in re-establishing full contact with Voyager 2 by using its highest-power transmitter to send an "interstellar shout" that righted the distant probe's antenna orientation, the space agency said Friday.
Launched in 1977 to explore the outer planets and serve as a beacon of humanity to the wider universe, it is currently more than 12.3 billion miles (19.9 billion kilometers) from our planet—well beyond the solar system.
ISS partners seek to maximize use of station through 2030
