https://buff.ly/4bB97iJ The dwarf planet Ceres hosts permanently shadowed areas in its polar regions, and these regions are an interesting analog to Mercury and the Moon. Ceres’ permanently shadowed regions were mapped by NASA’s Dawn spacecraft, and, thanks to scattered sunlight, bright deposits were discovered in a fraction of the permanently shadowed regions. To arrive at a clearer understanding of the nature of cold-trapped ice deposits on Ceres, researchers from the Planetary Science Institute and NASA’s Goddard Space Flight Center constructed improved shape models of permanently shadowed region-hosting craters.

Perseverance views Phobos transit (2024) | NASA's Perseverance Mars rover used its Mastcam-Z camera to capture the silhouette of Phobos, one of the two Martian moons, as it passed in front of the Sun on Feb. 8, 2024. This is one of several transits of Phobos that NASA's Mars rovers have captured. By comparing the various recordings, scientists can refine their understanding of the potato-shaped moon's orbit, learning how it's changing. Eons from now, Phobos' orbit is expected to eventually send the moon toward the Red Planet's surface. NASA/JPL-Caltech/ASU/MSSS/SSI

To the Moon and back. 🌕 Humans first landed on the Moon in 1969. So why is there now renewed interest in missions to the Moon? Well, Space throws up lots of challenges that drive innovation. And NASA - National Aeronautics and Space Administration and other space agencies want to establish a research presence on the Moon to explore and also establish a base for further exploration of our Solar System. We’ve been supporting space missions for more than 60 years. So what does this next generation of lunar missions mean for us? Make it your mission to find out: https://lnkd.in/gSYytN9a

As I commented below, design impacts the environment - here in the form of sound power. This is an interesting use case for test and measurement microphones from GRAS Sound & Vibration
GRAS Microphones Used to Calculate the Sound Power of a NASA Rocket Launch As the SLS Artemis-I mission lifted off on 16 November 2022 from Kennedy Space Center in Florida, USA, scientists were measuring the sound intently – using GRAS 46BE 1/4" CCP Free-field microphones. Their goal was to calculate the sound power of a rocket launch. And not just any rocket, but NASA’s Space Launch System (SLS) – the most powerful orbital rocket successfully launched. Now, Makayle Kellison and Kent Gee have published their peer-reviewed findings in an exciting JASA Express Letter from the Acoustical Society of America – and both the results and the methodology behind are well worth a read. The article is open-access, and you can find it right here: https://lnkd.in/d2zBKiNC

I predict specular at some wavelength will eventually be observed coming from a distant exoplanet using an advanced sensor.
#PPOD: Sunlight Reflecting Off a Lake This image shows the first flash of sunlight reflected off a hydrocarbon lake on Saturn's moon Titan. The glint off a mirror-like surface is known as a specular reflection. This kind of glint was detected by the visual and infrared mapping spectrometer (VIMS) on NASA's Cassini spacecraft on July 8, 2009. It confirmed the presence of liquid in the moon's northern hemisphere, where lakes are more numerous and larger than those in the southern hemisphere.

NASA Twin Study: Telomere Length Changes in Scott Kelly, the ISS Astronaut In my perspective, the most noteworthy revelation from the NASA twin study was the elongation of Scott Kelly's telomeres as an adaptive response to the challenging conditions of space, as outlined in this study: https://lnkd.in/ezQ2WM7K. Scott Kelly experienced alterations in his DNA, including telomere elongation, which were not observed in his twin brother, providing valuable insights into the impact of space travel on human health. The observed changes in telomere length during space travel are unsurprising and may signify an adaptive response to significant space stressors, including radiation. Concerning the NASA Twin Study, we previously reported that telomere elongation may be attributed to a well-established biological adaptive response to the space environment [1]. Interestingly, studies in high background radiation areas of Ramsar, Iran [2], and Kerala, India [3], found no alterations in telomere length. However, the NASA Twin Study [4] revealed a significant change, potentially associated with the presence of high linear energy transfer (LET) relativistic particles in space. While protons are recognized as low-LET particles, high-charge and energy (HZE) particles possess heightened energies and LET values [5]. Despite their low abundance, HZE particles traversing a cell nucleus induce nearly irreparable DNA damage due to a very high rate of energy deposition in living cells [6]. In an e-letter published in Science, Mortazavi et al. expressed concerns about the NASA Twins Study, which examined the biological effects of a year-long spaceflight on a male astronaut compared to his monozygotic twin [7]. The authors of the e-letter suggest that the study did not adequately address the potential impact of space radiation, especially HZE particles, on telomere length and telomerase activity. They also propose the possibility that telomere elongation during space flight could be an adaptive response to the space environment but might also increase the astronaut's long-term risk of cancer [8]. Additionally, they suggest that the study could provide insights into the differences between low-dose exposures to low- vs. high-LET radiation.

What a difference 55 years can make. This is the first delivery to a moon by a private craft.
Professional space evangelist | Communications Director at Privateer Space + Orbital Insight 🛰️
WE ARE BACK ON THE MOON 🙌 The first American landing on the Moon in half a century and the first ever by a commercial company. A company from Space City, as it should be. Congratulations Stephen Altemus, Kam Ghaffarian, Tim Crain, Josh Marshall, Justin Kugler, and all the other wonderful people at Intuitive Machines on an incredible, ground-breaking accomplishment. And, as well, to all the people at NASA who laid out a vision for – and have been working so hard on – the CLPS program. And shout out to my friend Gary Jordan, of course, joining Josh on the broadcast. This century's lunar exploration and, more importantly, development, is at last underway.
