News Explorer is a terrific news reader ★★★★★ I follow roughly a 100 news sites and blogs. I have used a number of different RSS aggregators (there are several great ones out there) but I have just moved over to New Explorer. It is working quite well. There was a small problem that.
Explorer 1.3.5 (stable) You can download Explorer 1.3.5 below. There's no need to install anything, simply extract the executable and run it. Download 32-bit. Explorer 4 was designed to further investigate the radiation belt around Earth, discovered during the Explorer 1 and 3 missions. The space satellite, which was part of the notbale Explorer mission series that launched the United States into the Space Age, made the first detailed measurements of charged particles (protons and electrons) trapped.

Explorer 4 was an Americansatellite launched on July 26, 1958. It was instrumented by Dr. James van Allen's group. The Department of Defense's Advanced Research Projects Agency had initially planned two satellites for the purposes of studying the Van Allen radiation belts and the effects of nuclear explosions upon these belts (and the Earth's magnetosphere in general), however Explorer 4 was the only such satellite launched as the other, Explorer 5, suffered launch failure.
Explorer 4 was a cylindrically shaped satellite instrumented to make the first detailed measurements of charged particles (protons and electrons) trapped in the terrestrial radiation belts.
Mission[edit]
Launched from a Juno I rocket, the mission remained secret from the public for six months.[1]

The satellite telemetry was analyzed for three Operation Argus nuclear weapons tests at high altitude.
An unexpected tumble motion of the satellite made the interpretation of the detector data very difficult. The low-power transmitter and the plastic scintillator detector failed September 3, 1958. The two Geiger-Müller tubes and the caesium iodide crystal detectors continued to operate normally until September 19, 1958. The high-power transmitter ceased sending signals on October 5, 1958. It is believed that exhaustion of the power batteries caused these failures. The spacecraft decayed from orbit after 454 days on October 23, 1959.
