Can we use ground penetrating radar frequencies with ground based telescopes into solar system planets to see their subsurfaces?
If we use ground penetrating radar frequencies with radiotelescopes could we see what’s beyond the surface of planets?
Can we observe planets surfaces and subsurfaces using radio/micro/IR waves passively? Can radiotelescopes as arecibo image the subsurface of an asteroid or a planet penetrating into atmosphere and surface: several cm of metal or rock? How do we observe non-radio-emiting planets (earth, venus, mars, asteroids…etc) with radiotelescopes? Could we use arecibo radar frequencies to read a message in a paper in an alluminium ball buried in a planet? Can radar frequencies of 13 cm aprox be used to read a paper buried in an aluminium ball beneath the surface (of a planet for example)? How does ground based synthetic aperture radar work? Since few gamma and cosmic rays can pass through our atmosphere, can we image Earth with them and using their penetration image its subsurface? What would it look like through a telescope if all the planets aligned? Has any optical or radio telescope been able to capture images of the surface or atmosphere of an extra-solar planet? Can we capture signals from the voyager satellites by making a powerful radio or radar or something? Does radar uses latitude and longitude? Can extremely low frequency radiowaves pass through interplanetary, interstellaer, intergalectic, and farther space? Since some gamma and cosmic rays pass through our atmosphere could we take advantage of their penetration power and get an image of the subsurface with them? Can the satellite orbit at any altitude? How does a satellite transmit the photos from space to earth which may be million miles away? How big would the sun look on other planets? How long does it take for a radio signal from Earth to reach the moon? If we can see distant galaxy using Hubble or some other telescopes, can we see the flag on moon? Are there any satellites visible from Earth by the naked eye? If the Hubble telescope were aimed at the newly discovered planet around proxima b, would it reveal much detail about the planet's surface? Which satellites are visible from earth? How far is Pluto from the Sun and how does its proximity affect the planets characteristics? How are radar detectors legal? Do astronauts become so used to the Earth's features that they can spot any place from above? Even at night? What type of electromagnetic radiation can we use to see small things through a 1 or 2mm layer of aluminiuin an earth like planet from here? Can extremely low radio frequencies (ELF) pass through INTERPLANETARY and INTERSTELLAR medium?  do some of them pass through it? What is the scope of planetary science in USA? Can radio waves and microwaves penetrate soil/rock/walls/metal? What kind and magnification of telescope will help to see Apollo mission landing sight? Are there satellites with HD cameras orbiting other planets, which the public can access? If so, what are they?
