A Shining Beacon of International Collaboration for Science and Peace

Dragon Crew-11 headed to ISS July 31 with Commander Zena Cardman, Pilot Edward “Mike” Fincke, Cosmonaut Oleg Vladimirovich Platonov and JAXA Astronaut Kimiya Yui. Current astronauts are Anne McClain, Nichole Ayers and Jonny Kim from NASA, Takuya Onishi from JAXA, and Kirill Peskov, Sergey Ryzhikov and Alexey Zubritsky from Roscosmos. ISS is in its 24th year of continuous Human occupation, with 4,000+ science projects completed after proposals from 108+ countries. They are using a 3D bioprinter to mimic human tissue, conducting stem cell studies, researching artificial retinas to help people with retinitis pigmentosa, and manufacturing ZBLAN optical fiber in microgravity as that eliminates imperfections arising in Earth fabrication. ZBLAN fiber improves transmission. Tiangong Space Station (TSS), in its 5th year of continuous Human occupation, is expected to reach at least 10 years. Plans are in the works for international and commercial crew and for expansion of the station. Current taikonauts on the station are Chen Dong, Chen Zhongrui and Wang Jie, and they are studying adaptability of ancient microbes to radiation and weightlessness, as well as testing high-strength steel and tungsten alloys with TSS equipment able to cool atoms to ultra-low temperatures. American Astronautical Society announced they hoped to hold an online-only version of the cancelled ISSRD conference.

Habitable World Observatory Meeting Plans Next Steps for 2040s Search for Interstellar Planets

Space Telescope Science Institute, Johns Hopkins University and NASA Exoplanet Science Institute are holding “Towards the Habitable Worlds Observatory: Visionary Science and Transformational Technology” meeting on July 28-31 in Washington DC. Habitable Worlds Observatory (HWO) is the next NASA astrophysics flagship mission, drawing upon the legacy of Hubble, Webb and Roman Space Telescopes – potentially launching in early to mid-2040s. HWO will utilize ultraviolet, optical, and infrared technologies, and is planned to have a mirror large enough to find and study atmospheres of at least 25 potentially habitable worlds around other stars. There are over 5,000 confirmed exoplanets to date. Results from multiple HWO working groups will be showcased at this meeting with contributions from global astronomy and engineering communities. A livestream of plenary sessions will be available on the STScI Research YouTube Channel. Giada Arney from Goddard Space Flight Center will open the meeting with a talk on “Are we alone? The search for life with HWO”. Other speakers include Astronaut John Grunsfeld who repaired Hubble, Bruce Macintosh from UC Santa Cruz, Jean-Baptiste Ruffio UC San Diego, Xinfeng Xu from Northwestern University, and Tracy Becker of SwRI. The program also includes in-person and digital posters. HWO has made significant progress in the past year: NASA established a dedicated Technology Maturation Project Office at Goddard, which is collaborating with JPL, Ames and Marshall Centers.
