Pathways to Sustainable Planetary Science

Autor: Ćuk, Matija, Virkki, Anne K., Kohout, Tomáš, Lellouch, Emmanuel, Lissauer, Jack J.

Climate change is a major impending threat to the future of humanity. According to the International Panel on Climate Change (IPCC), our emissions are estimated to have caused 0.8 deg C-1.2 deg C of anthropogenic global warming (AGW) above pre-indust

Linking the Solar System and Extrasolar Planetary Systems with Radar Astronomy: Infrastructure for 'Ground Truth' Comparison

Autor: Lazio, Joseph, Bonsall, Amber, Brozovic, Marina, Giorgini, Jon D., O'Neil, Karen, Rivera-Valentin, Edgard, Virkki, Anne K., Cordova, Francisco, Busch, Michael, Campbell, Bruce A., Edwards, P. G., Fernandez, Yanga R., Kruzins, Ed, Pinilla-Alonso, Noemi, Slade, Martin A., Venditti, F. C. F.

Planetary radars have obtained unique science measurements about solar system bodies and they have provided orbit determinations allowing spacecraft to be navigated throughout the solar system. Notable results have been on Venus, Earth's "twin," and

Arecibo Radar Observations of Near-Earth Asteroid (3200) Phaethon During the 2017 Apparition

Autor: Taylor, Patrick A., Rivera-Valentin, Edgard G., Benner, Lance A. M., Marshall, Sean E., Virkki, Anne K., Venditti, Flaviane C. F., Zambrano-Marin, Luisa F., Bhiravarasu, Sriram S., Aponte-Hernandez, Betzaida, Sanchez-Vahamonde, Carolina Rodriguez, Giorgini, Jon D.

We report Arecibo S-band (2380 MHz; 12.6 cm) radar observations of near-Earth asteroid (3200) Phaethon during the December 2017 apparition when Phaethon passed within 0.07 au of Earth. Radar images with a resolution of 75 m per pixel reveal a roughly
