The Kid Should See This 🌈🪐✨

💁🏻‍♀️ ICYMI: 🎈🧭 What was the first human-made object to break the sound barrier? And why do we always see the same side of the #moon? Mark Rober tackles these questions and more through creative experiments.

In this fast-paced #video, he goes up in a hot air balloon, tests liquid density with soda cans, drops metal in mercury, and even rides on top of a moving train to demonstrate scientific principles.

Lunokhod 2 drove on about 800 m north. On the next day it drove all the way back along its tracks to the southernmost point, turned and drove all the way back to the top right corner of the map. This made a triple traverse, useful for magnetometer data again and testing driving ability. We will look at some of this in more detail next.

We move on op the 5th map of the Lunokhod 2 route. A quick look today and more detail tomorrow as it is past my bedtime. The rover drove out of Margo crater and a bit further southeast, stopping beside a little crater on 19 February. On 20 February it drove 1 km northeast and stopped by another small crater for the 2nd lunar night. Early on lunar day 3 it made another cross-shaped 'special magnetometer experiment' around that crater. Then it drove on...

The 5th section of the Lunokhod 2 route map. The rover moved southeast after leaving Margo crater, then northeast and stopped for its 2nd night. The next morning saw another cross-shaped magnetic experiment, then a drive northeast. Then the rover drove rapidly right back along its tracks, turned and drove back again - making a triple traverse. The magnetometer was used along the path, and in fact during the whole mission, not just the special experiment areas.

Still working my way through my #Egypt photos. This is one of my absolute favourite shots. It was the Light and Sound show in the #Karnak temple and we had the incredible luck to have a full moon shining down on us as an addition to the light show. It was utterly stunning and breathtaking to walk through the smartly illuminated temple. We had the last show of the evening and were only 30 people instead of three thousand. It was incredible beautiful.

Vertical colour photo. It's night and we're standing in darkness between the giant columns, looking ahead to a path between them. The darkness gets interrupted by bright floodlights hidden behind the last two columns. They're throwing bright lights, illuminating two high columns on each side in a soft orange light and creating a criss cross shadow pattern on the ground. The light beams don't reach us. In the far back are a single obelisk and a broken wall getting hit by indirect light. Between the obelisk in the back and the column near us the bright glowing disk of the moon hangs low in the sky like a blue whisp hovering in the temple ruins. The rest of the visible sky is pitch black. The contrast between the orange sand stone or lime stone and the glowing blue moon creates a fascinating visual.

Spaceflight 🚀

@planet4589 : "When I was a kid 🧒, it was #LEO. Now, the frontier is out near the #asteroid belt, and the #Moon and #Mars are becoming part of where humanity just hangs out, maybe not yet as people, but with #robots. Meanwhile, #LEO is so normalized that it doesn’t take a #SpaceAgency to deal with it. You just call #SpaceX. Thousand years from now, perhaps more people live off Earth 🌌 than on it" cearkadia.edu.pl/jonathan-mcdo

The 4th section of the Lunokhod 2 route map brings us well into the hills, and into a crater called Margo, about 750 m across. At the south edge of the map the rover tracks show a struggle to climb out of the crater, eventually resolved by driving east, more diagonally up the slope. Reports that Lunokhod 2 imaged a crescent Earth above the hills might refer to this location, where the slope might allow the cameras to see Earth to the southwest. #maps #moon #luna21 #lunokhod2

Part 4 of the Lunokhod 2 route map. Here the rover enters the map at the top (north) and drives south, entering a 750 m diameter crater called Margo. It struggles to climb its southern rim and exits diagonally up the slope to the southeast.
