Teams with NASA’s Exploration Ground Systems and primary contractor Amentum integrate the SLS (Space Launch System) Moon rocket with the solid rocket boosters onto mobile launcher 1 inside High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center on Sunday, March 23, 2025. Artemis II is the first crewed test flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.

One of the first verified predictions of general relativity is the gravitational deflection of starlight. The effect was [first observed in 1919 during a total solar eclipse.](https://briankoberlein.com/post/einstein-and-eddington/) Since stars appear as points of light, the effect is seen as an apparent shift in the position of stars near the eclipse. But the effect happens more generally. If a distant galaxy is obscured by a closer one, some of the distant light is gravitationally lensed around the closer galaxy, giving us a warped and distorted view of the faraway stars. This effect can also magnify the distant galaxy, making its light appear brighter, and we have used this effect to observe some of the most distant stars in the Universe.

In-situ resource utilization will likely play a major role in any future long-term settlement of the Moon. However, designing such a system in advance with our current level of knowledge will prove difficult, mainly because there's so much uncertainty around both the availability of those resources and the efficacy of the processes used to extract them. Luckily, researchers have tools that can try to deal with both of those uncertainties - statistical modeling. A team from Imperial College London, the University of Munich, and the Luxembourg Institue of Science and Technology recently released a pre-print paper on arXiv that uses a well-known statistical modeling method known as Monte Carlo simulation to try to assess what type of ISRU plan would be best for use on the Moon.

Even though Jupiter's moon Io is considered the most volcanically active world in the Solar System, Venus actually has more volcanoes and volcanic features on its surface. For a long time, scientists thought that most of these features and volcanoes were ancient remnants of the planet's geological past. However, newer research shows that Venus is still volcanically active.
