Explorer 34
Explorer 34 (IMP-F, IMP-4), was a NASA satellite launched as part of Explorer program. Explorer 34 as launched on 24 May 1967 from Vandenberg Air Force Base, California, with Thor-Delta E1 launch vehicle. Explorer 34 was the fifth satellite launched as part of the Interplanetary Monitoring Platform program, but was known as "IMP-4" because the preceding launch was more specifically part of the "Anchored IMP" sub-program. The spacecraft was put into space between the launches of Explorer 33 (IMP-D / AIMP-1) in 1966 and Explorer 35 (IMP-E / AIMP-2) in July 1967, but the next satellite to use Explorer 34's general design was Explorer 41 (IMP-G / IMP-5), which flew in 1969. Launch Explorer 34 was placed into a high-inclination, highly elliptical orbit. The apogee point was located near the ecliptic plane and had an initial local time of about 19:00 hours. The spacecraft was spin-stabilized and had an initial spin period of 2.6-seconds. The spin vector was approximately perpendic ...

Space Physics
Space physics, also known as solar-terrestrial physics or space-plasma physics, is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System. As such, it encompasses a far-ranging number of topics, such as heliophysics which includes the solar physics of the Sun, the solar wind, planetary magnetospheres and ionospheres, auroras, cosmic rays, and synchrotron radiation. Space physics is a fundamental part of the study of space weather and has important implications in not only to understanding the universe, but also for practical everyday life, including the operations of communications and weather satellites. Space physics is distinct from astrophysical plasma and the field of astrophysics, which studies similar plasma phenomena beyond the Solar System. Space physics utilizes in situ measurements from high altitude rockets and spacecraft, in contrast to astrophysical plasma that relies deduction of theory and astronomical obse ...

Explorer 41
Explorer 41, also called as IMP-G and IMP-5, was a NASA satellite launched as part of Explorer program. Explorer 41 as launched on 21 June 1969 on Vandenberg AFB, California, with a Thor-Delta E1 launch vehicle. Explorer 41 was the seventh satellite launched as part of the overall Interplanetary Monitoring Platform series, though it received the post-launch designation "IMP-5" because two previous flights had used the "AIMP" ("Anchored IMP") designation instead. It was preceded by the second of those flights, Explorer 35 ( MP-E / AIMP-2), launched in July 1967. Its predecessor in the strict IMP series of launches was Explorer 34, launched in May 1967, which shared a similar design to Explorer 41. The next launch was of an IMP satellite was Explorer 43 (IMP-I / IMP-6) in 1971. Spacecraft and mission Explorer 41 (IMP-G) was a spin-stabilized satellite placed into a high-inclination, highly elliptical orbit to measure energetic particles, magnetic fields, and plasma in cisluna ...
