A few months back, the South Eastern Amateur Radio Group committee elected to purchase and install an APRS capable weather station. The weather station is up and running now, broadcasting via APRS throughout the Southeast of Ireland (on 144.800Mhz) and, consequently the data is accessible here. The equipment used is a Peet Bros. Ultimeter 2100.
“The high resolution camera on NASA’s Mars Reconnaissance Orbiter captured its first image of Mars in the mapping orbit, demonstrating the full resolution capability, on Sept. 29, 2006. The High Resolution Imaging Science Experiment (HiRISE) acquired this image at 8:16 AM (Pacific Time), and parts of the image became available to the HiRISE team at 1:30 PM. With the spacecraft at an altitude of 280 kilometers (174 miles), the image scale is 29.7 centimeters per pixel (about 12 inches per pixel).”
280 kilometers away, and 29.7centimeters per pixel. Thats impressive, it makes you wonder how good the satellites are that are pointed down at us (even by our allies).
