Artemis: An Overview of NASA's Activities to Return Humans to the Moon

IEEE Aerospace Conference, 2022
NASA is well underway in its plans to return humans to the Moon and build long-term infrastructure both in orbit and on the surface. Following the Artemis I and Artemis II flight tests, NASA will begin crewed landings and regular missions to the Moon ...

The Artemis Program: An Overview of NASA's Activities to Return Humans to the Moon

IEEE Aerospace Conference, 2020
NASA is developing a two-phased approach to quickly return humans to the Moon and establish a sustainable presence in orbit and on the surface. The two phases run in parallel, and both have already begun, with selection of the first Gateway element, the ...

Micro cold traps on the Moon

Nature Astronomy, 2020
Water ice is thought to be trapped in large permanently shadowed regions in the Moon’s polar regions, due to their extremely low temperatures. Here, we show that many unmapped cold traps exist on small spatial scales, substantially augmenting the areas ...

Artificial Impacts on the Moon: Modeling 3D Seismic Propagation Effects with AxiSEM3D

The Planetary Science Journal
During the Apollo missions, used spacecraft were deliberately crashed into the Moon to provide large signals for the seismic experiments. We use AxiSEM3D and a variety of 1D and 3D models to model these impacts and propagate seismic waves across the Moon

The Unfinished Moon

Journal of Lesbian Studies, 2000
SUMMARY The author explores several questions. She asks: What does it mean to exist as a lesbian writer given that we have no lesbian homeland or ancestral tongue, little presence in the external narrative matrix, a scarcity of close friendships among ourselves, a lack of contact with younger lesbian writers, and an erasure of our lesbianism due to ...

Oxygen isotope identity of the Earth and Moon with implications for the formation of the Moon and source of volatiles

Proceedings of the National Academy of Sciences of the United States of America
Significance The isotopic similarity of Earth and Moon rocks is a significant puzzle in geo- and cosmochemistry, contradicting prevailing Moon formation models.

Sustainable in-situ resource utilization on the moon

, 2020
We propose that current in-situ resource utilization schemes based on mining of water resources on the Moon is unnecessary and unsustainable. Life support systems are capable of recycling with high efficiency. Burning of hydrogen propellant and oxygen is

The Moon Tilt Illusion

Perception, 1998
Besides the familiar moon illusion [eg Hershenson, 1989 The Moon Illusion (Hillsdale, NJ: Lawrence Erlbaum Associates)], wherein the moon appears bigger when it is close to the horizon, there is a less known illusion which causes the moon's illuminated side to appear turned away from the direction of the sun.
