The Caralis Chaos on Mars

0

An image captured by ESA’s Mars Express space probe’s High Resolution Stereo Camera (HRSC) shows the region of the planet Mars called Caralis Chaos. At first glance, it may seem like just another Martian area dotted with craters and wind-carved mounds, but when the red planet was young, it was home to Lake Eridania, larger than all the lakes on Earth. It covered an area of ​​more than a million square kilometers, including Atlantis Chaos, an area close to Caralis Chaos. That lake gradually dried up as the environmental collapse transformed an Earth-like planet into the one we see today.

A few hours ago the Ariane 6 rocket was launched from the base in French Guiana and conducted its maiden mission in the version with two side boosters. Over the course of approximately 2 hours and 40 minutes, the various phases of the flight were conducted, which among other things tested the great innovation of this rocket which consists of the possibility of restarting the Vinci engine which powers the upper stage. This new possibility allows it to place satellites in different orbits in the same mission.

ESA and the Euclid Consortium have presented the first scientific results obtained thanks to the Euclid Space Telescope within the ERO (Early Release Observations) program. That’s a series of scientific articles partly written directly by the Consortium’s researchers and partly by different teams of researchers who worked within the ERO program. Some images illustrate the possibilities of this instrument but research into some of the major cosmological mysteries goes far beyond the aesthetics of photos.

A few hours ago, SpaceX’s Crew Dragon Freedom spacecraft was launched atop a Falcon 9 rocket from the Kennedy Space Center on the Axiom Mission 3, or simply Ax-3, mission. After about twelve minutes, it successfully separated from the rocket’s last stage. It will spend about 14 days in orbit, almost all of which will be docked at the International Space Station. It also serves commercial purposes in a collaboration between SpaceX, Axiom Space, and various companies and national space agencies to access the Station for the purpose of conducting tasks useful for the development of new technologies and for scientific research.

ESA has presented the first official images captured by its Euclid space telescope. After some delays due to problems with the fine guidance sensor, it was possible to calibrate Euclid’s instruments and obtain the extraordinary precision of observations necessary for its mission. The result is a resolution that allows a quantity of detail never seen before to be included in the images, be it galaxies, stars, or other objects, often discovered by Euclid. The presentation showed the results both with distant objects such as the Perseus galaxy cluster and with others close in astronomical terms such as the Horsehead Nebula.
