I’d like to reemphasize this. The dust you see is not settling. It is still going uphill when it flies over the horizon and out of view. It is like a rocket that has curved below the horizon but is still climbing. If you get this, it makes sense why it clears the view so fast. /1

Starship always puts on a display, even during a RUD.

Starship flip maneuver and landing burn on its fifth flight test. Vehicle improvements ensured flaps were protected from high heating, resulting in a controlled entry and high accuracy splashdown at the targeted area in the Indian Ocean

Houston, we have a new spacesuit. At the #IAC2024 in Milan, @Axiom_Space unveiled the flight design of its lunar spacesuit that @NASA_Astronauts will wear during the #Artemis III mission when they set foot on the Moon for the first time in over 50 years.

Looking at the world through a microscope 🧵 1. Terrifying photo of an ant's face
This picture is an award-winning close-up photo of an ant, captured by Lithuanian photographer Eugenijus Kavaliauskas. The Nikon’s Small World Photomicrography Competition seeks to “recognize excellence in photography through the microscope”.

On the eve of the Starship test flight, a reminder of why full reusability is a game changer for access to space... While the industry is following the red line, SpaceX is on a different curve. Note: a straight line is an exponential on this semi-log graph.

BREAKING: Asteroid 2024 PT5 to Become Earth's Mini-Moon Asteroid 2024 PT5, discovered August 7, will become a "mini-moon" from September 29 to November 25, 2024. The 10-meter NEO will be temporarily captured by Earth's gravity but won't complete a full orbit before returning to its solar path.

In the lunar phase calendar, the New Moon is the first of four major phases…but beginning this weekend, we will actually get a new moon! Essentially, Earth’s gravity captures an asteroid passing by our planet, which becomes a small moon for a temporary period. In this case, 2024 PT5, which is from the Arjuna asteroid belt, will remain with us for roughly two months before leaving orbit and moving on. The science of these “mini-moons” is quite interesting and they occur fairly frequently!

This is a real photo captured from Earth. This is Mars the moment it emerged after being occulted by the moon, captured with my 14” telescope and formatted as a mobile wallpaper if you want it. I’m posting my work as mobile wallpapers daily, I’ll do another tomorrow. Stay tuned!

Heads up! 2 large asteroids will safely pass our planet this week. So there's no danger, but you can see them in a small telescope. In an astronomical coincidence, they'll both appear best on Friday night, June 28. earthsky.org/earth/2-large-a… 📸 ESA/ P. Carril.

To the Moon and beyond🚀 Debuting during @NASAArtemis IV, the Block 1B configuration of the SLS rocket will have updates allowing it to carry over 83,700 lbs to the Moon, including @NASA_Orion and large payloads for deep space missions. LEARN MORE>>go.nasa.gov/3KRE8ns
This infographic depicts the SLS (Space Launch System) in the Block 1B configuration that will be used beginning with Artemis 4. The left side of the graphic explains the difference between the Block 1 and Block 1B designs and shows a person standing next to the rocket showing the difference in size. On the top right side of the graphic, there is a graphic depicting the Lunar I-Hab. Below is a breakdown of the internal design of the SLS. It also details a few advantages this configuration of the rocket will have and discusses the capability of having two or more payloads launched by the same rocket. Credit: NASA/Kevin O'Brien

We want to discover Earth twins. The world gave us #JWST. But mother nature, that vicious bitch, gave us active M dwarfs and put most of the habitable-zone planets around them. #Exoplanets5

That’s very good to hear! Starship has the green light from the FAA for Starship flight 5! How long will it take SpaceX to prepare for the next Starship launch? What do you think? 🔮

BREAKING: FAA will not require mishap investigation for IFT-4 of Starship "The FAA assessed the operations of the SpaceX Starship Flight 4 mission. All flight events for both Starship and Super Heavy appear to have occurred within the scope of planned and authorized activities."
