Probing Venus’ mountains — Science Information, February 12, 1972
Venus’ without end cloud-shrouded floor stays penetrable handiest through radio waves. A planetary radar workforce now studies result of a longer sequence of radar measurements of the topography of Venus that for the primary time supplies a view of floor peak diversifications round all of the circumference of the planet.
The ones observations had been taken through the Arecibo radio telescope in Puerto Rico, which was once probably the most robust radar gadget for mapping rocky our bodies in outer area till its surprising cave in in December 2020 (SN: 12/19/20 & 1/2/21, p. 8). The observatory additionally published historic lava flows on Venus and ice on Mercury (SN: 9/18/76, p. 181; SN: 11/9/91, p. 295). Arecibo’s maps of Mars and the asteroid Bennu helped NASA plan the Viking and OSIRIS-REx missions. Another amenities have planetary radar methods, however they aren’t as robust as Arecibo’s was once. Astronomers are including a radar transmitter to West Virginia’s Inexperienced Financial institution Telescope this is anticipated to rival or exceed Arecibo’s.
