NASA needs and trends in cryogenic cooling

Projected NASA needs in spaceborne cryogenic systems and recent results of NASA cryogenic cooling technology efforts in infrared astronomy, X-ray astronomy, gamma ray astronomy, liquid helium and space stations are discussed

The effects of a satellite power system on ground-based astronomy

The effects of power transmission from the solar power satellite and of radiation from the ground based rectennas on radio astronomy, radar astronomy, and optical astronomy are discussed. Interference sources, acceptable signal and noise levels, and conflicting site requirements for observatories and rectennas are considered

Using sounds and sonifications for astronomy outreach

Good astronomy pictures, like those of the HST, play an important and wellknown role in astronomy outreach, triggering curiosity and interest. This same aim can also be achieved by means of sounds. Here we present the use of astronomy-related sounds and data sonifications to be used in astronomy outreach. These sounds, which people are unlikely to hear in the normal course of things, are a good tool for stimulating interest when teaching astronomy. In our case, sounds are successfully used in ‘‘The sounds of science,’’ a weekend science-dissemination program heard on the principal national radio station, Radio Nacional de Espan˜a (RNE). But teachers can also easily make use of these sounds in the classroom, since only a simple cassette player is needed

Astrobites as a Community-led Model for Education, Science Communication, and Accessibility in Astrophysics

Support for early career astronomers who are just beginning to explore astronomy research is imperative to increase retention of diverse practitioners in the field. Since 2010, Astrobites has played an instrumental role in engaging members of the community -- particularly undergraduate and graduate students -- in research. In this white paper, the Astrobites collaboration outlines our multi-faceted online education platform that both eases the transition into astronomy research and promotes inclusive professional development opportunities. We additionally offer recommendations for how the astronomy community can reduce barriers to entry to astronomy research in the coming decade
