Yesterday, ESA’s Hera space probe blasted off atop a SpaceX Falcon 9 rocket from the Cape Canaveral together with the two nanosatellites Juventas and Milani. After about 76 minutes, it successfully separated from the rocket’s last stage and set on its course which in almost exactly two years will take it to the asteroid Didymos and its moon Dimorphos to examine the consequences of the impact of NASA’s DART spacecraft.

A few hours ago, the Sentinel-2C satellite of the Copernicus / GMES program blasted off from the Kourou base, French Guiana, atop a Vega rocket. After about 57 minutes, the satellite regularly separated from the rocket’s last stage and started sending signals. A few hours later it started deploying its solar panels. After a period of testing, it will replace the Sentinel-2A satellite, launched on June 23, 2015. This is the last launch of the original version of the Vega rocket.

The Caralis Chaos on Mars

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.
