Climate in Focus, Landsat Set to Continue 50-Year Earth Observation Mission

As NASA / USGS global monitoring collaboration nears half century, latest version Landsat 9 is to take off from Vandenberg Space Force Base on September 27 – controlled remotely by Launch Services Program at KSC, riding on ULA Atlas V 401. The 2.6 metric ton spacecraft, built by Northrup Grumman, is to provide observational continuity from 705km SSO as Landsat 8 reaches the end of fuel supply, having surpassed 5-year nominal mission duration. Operational Land Imager (OLI-2) and Thermal Infrared Sensor (TIRS-2) instruments are capable of recording in a total of eleven spectral bands: OLI-2, developed by Ball Aerospace, registers 9 visible and infrared wavelengths from 0.435–2.294μm with 30m resolution (with the exception of a panchromatic band with 15m resolution); TIRS-2, built at Goddard Space Flight Center, will detect infrared thermals from 10.60–12.51μm with 100m resolution (30m with post processing). The mission comes as UN Intergovernmental Panel on Climate Change determines global warming ‘unequivocally’ anthropogenic in cause and world and national leaders grow increasingly adamant that data-driven solutions to address global warming be implemented. National Space Council Executive Secretary Chirag Parikh has indicated USA VP Kamala Harris considers continuity of Earth observation to be a top priority which should influence upcoming selection of candidates for National Space Council Users’ Advisory Group (Image Credits: NASA, USGS)

Visionary Long-Range Concepts Presented at NIAC 2021 and 7th Interstellar Symposium

NASA Innovative Advanced Concepts (NIAC) 2021 is being held September 21-23 updating progress on Phase 1-3 diverse research studies. Originally set as an in-person event in Tucson AZ prior to Interstellar Research Group 7th Interstellar Symposium on Sep 24-27, NIAC will now be online and livestreamed for the >45 speakers. Some of the Phase 1 studies speakers are (TL-BR) Sigrid Close on Exploring Uranus through SCATTER: Sustained ChipSat / CubeSat Activity Through Transmitted Electromagnetic Radiation; Steven Oleson – A Titan Sample Return Using In-Situ Propellants; Jane Shevtsov – Making Soil for Space Habitats by Seeding Asteroids with Fungi; Phase 2: Kerry Nock – Pluto Hop, Skip, and Jump; Jeffrey Balcerski – Lofted Environmental Venus Sensors; Phase 3: William Whittaker – Robotic Technologies Enabling the Exploration of Lunar Pits; Nick Solomey – Cube-Sat Space Flight Test of a Neutrino Detector. IRG 7th Interstellar Symposium at Tucson Marriott University Park plans for ~60 speakers, 100 participants, 4 seminars, 18 posters, 2 working tracks and 5 tour locations. Keynote speakers are Esther Dyson, Mark Shelhamer, Avi Loeb, David Brin and Homer Hickam. Topics covered include propulsion studies, communications challenges, moving faster than light, cryopreservation, pulsed plasma rocket, gravitational wave transmitter, extrasolar object intercept, an interstellar university, wormholes & warpdrives, and icy moon geothermal energy generation. The Art of Planetary Science: Space Travel also opens at Univ of Arizona LPL Sep 24. (Image Credits: NASA, IRG, K. Miller, University of Arizona Lunar and Planetary Laboratory)
