TLDR:

NASA landed the Perseverance Rover on Mars, gaining a wealth of new data regarding the planet. It also included the Ingenuity Flyer, which preformed the first powered flight on another planetary body and gave airborne data about the planet.

NASA also launched the James Webb Space Telescope, which will have a significantly longer range than any previous space telescopes, and can see into light wavelengths that has previously been invisible to sensors. Poetically, it launched on Christmas Day.

SpaceX further refined their launch techniques to make space launches significantly more cost effective. Additionally, they finally managed to land their Starship module, which will be able to carry the heaviest payload since Saturn V while retaining the reusability of their Falcon-class rockets. These various methods of cost control will make the goal of space travel, exploration, exploitation (satellites, space stations, and hopefully eventual planetary bases and asteroid mines) that much more likely.

The Ozone Layer has continued healing and is significantly strong than it was even a decades ago. Of course, you wouldnt know that if you listened to the MSM or the climate cultist.

New technology has been introduced that allow us to grow coral reefs through the usage of healthy coral populations, then seed the new coral into damaged reefs. This has already helped many reefs start recovering from decades of damage. Once again, you would have never known this from listening to the usual suspects.

Microbes in the ocean are evolving the ability to be able to digest plastic, and it has already caused a noticeable jump in water quality in the regions where the microbes exist. Said microbes also seem to be evolving faster in more polluted water.

Not covered in any direct article, but brought up by one of the host. The Amazon Rainforest has seen its plant life absolutely explode in response to increased CO2 in the atmosphere.
