NASA’s car-sized Perseverance (Percy) Mars rover has been had at work carrying out its science campaign in Jezero Crater on the Red Planet, but it’s equally been busy scouting for sites for NASA’s planned Mars Sample Return (MSR) mission, which is a joint mission with the European Space Agency. One of the many tasks for Percy has been to collect sample tubes that MSR will eventually return to Earth for further analysis, having collected its ninth sample on July 6. This most recent sample is especially intriguing as it’s the first taken from the Jezero’s delta itself, which is believed to be one of the most ideal locations to search for past life on the Red Planet.

Well, this is the week for distant galaxies, isn’t it? Not only has JWST revealed some of the most distant ones ever seen in infrared, but other observatories are studying them, too. Astronomers at the Cosmic Dawn Center in Copenhagen recently discovered several interesting ones in the early Universe. However, they had to get through clouds of dust to do it. Their observations revealed several interesting characteristics of objects that existed when the Universe was only a tenth of its current age.

After exploring Mars for more than a year, China’s Tianwen-1 space probe has successfully taken images covering the entire Red Planet, China’s National Space Administration (CNSA) announced on June 29. Tianwen-1, which translates to “quest for heavenly truth”, consists of six separate spacecraft: an orbiter, two deployable cameras, lander, remote camera, and Zhurong rover. The images in question were taken by the orbiter while circling Mars 1,344 times, capturing images of the Red Planet from every angle while Zhurong explored the surface. in the statement, CNSA said the probe has now completed all of its tasks, which included taking medium-resolution images covering the entire planet.

On December 25th, 2021, the James Webb Space Telescope launched from Cape Canaveral bound for space. After many years of delays, retesting, and cost overruns, the next-generation observatory made it to orbit without any hiccups or complications. What followed was several weeks of deployment as Webb unfolded its arms, sunshield, primary mirror (consisting of eighteen gold-coated beryllium segments), and secondary mirror. By late January, the space telescope had flown to the Sun-Earth L2 Lagrange Point, where it will remain for the entirety of its mission.

When Galileo pointed his telescope at Jupiter 400 years ago, he saw three blobs of light around the giant planet, which he at first thought were fixed stars. He kept looking, and eventually, he spotted a fourth blob and noticed the blobs were moving. Galileo’s discovery of objects orbiting something other than Earth—which we call the Galilean moons in his honour—struck a blow to the Ptolemaic (geocentric) worldview of the time.
