HYDRA - HYDRA is a collection of electrostatic analyzers designed for high resolution observations of electron and ion velocity distributions in the earth's polar magnetosphere. HYDRA is being flown on the POLAR spacecraft.

Magnetic Fields Experiment (MFE) - The Magnetometer on the Polar Spacecraft is a high precision instrument designed to measure the magnetic fields in the high and low altitude polar magnetosphere. NASA Goddard Space Flight Center.

Polar Charge and Mass Magnetospheric Ion Composition Experiment (CAMMICE) - An energetic composition experiment on the Polar spacecraft Los Alamos National Laboratory

Polar Electric Fields Instrument (EFI) - The Electric Field Instrument (EFI) on the Polar spacecraft measures the three components of the ambient vector electric field and the thermal electron density. NASA Goddard Space Flight Center.

Polar Ionospheric X-ray Imaging Experiment (PIXIE) - PIXIE is an electronic camera which images the earth's aurora in x-rays on the Polar spacecraft.

Polar Plasma Wave Instrument (PWI) - The PWI is aboard the Polar spacecraft and is designed to provide measurements of plasma waves in the Earth's polar regions over the frequency range from 0.1 Hz to 800 kHz.

Polar Source/Loss-Cone Energetic Particle Spectrometer (SEPS) - SEPS consists of two independent telescopes on the Polar spacecraft which measure both the energetic electron, and ion fluxes in the vicinity of the magnetic field-aligned loss, and source cone regions with high

Polar Spacecraft - The Polar spacecraft was launched in 1996 to obtain data from both high- and low-altitude perspectives of the region over the poles of the Earth. NASA Goddard Space Flight Center.

Polar Ultraviolet Imager - This instrument operates in the far ultraviolet (FUV) and is capable of imaging the auroral oval in sunlight and in darkness. University of Washington website. University of Washington.

Polar Ultraviolet Imager - This instrument operates in the far ultraviolet (FUV) and is capable of imaging the auroral oval in sunlight and in darkness. NASA Marshall Space Flight Center website.

POLAR ultraviolet Imager Current Image - This page features the most recent UV image of the Earth taken by NASA's Ultraviolet Imager aboard the POLAR spacecraft and is updated about every 7 minutes.

Polar Visible Imaging System (VIS) - VIS is a set of three low-light-level cameras on the POLAR spacecraft. Two of these cameras share primary and some secondary optics and are designed to provide images of the night-time auroral oval at visible wavelengths. A third camera is used to monitor the directions of the fields-of-view of these sensitive auroral cameras with respect to sunlit Earth. University of Iowa.

Thermal Ion Dynamics Experiment/ Plasma Source Instrument (TIDE/PSI) - This POLAR space craft investigation is designed to obtain mass-resolved observations of the velocity distribution of low energy or core plasmas of the magnetosphere, especially the polar regions. This includes the partial pressure, wind velocity and temperature of the principal ion species whose source lies in the terrestrial atmosphere and ionosphere. NASA Marshall Space Flight Center.

Toroidal Imaging Mass-Angle Spectrograph (TIMAS) - TIMAS is a first order double focusing (angle and energy), imaging spectrograph aboard the POLAR spacecraft designed to gather data to study the magnetosphere, the ionosphere, and solar interactions.

Visible Imaging System (VIS) Current Image - The image on this page is generated from data collected by the University of Iowa's Visible Imaging Investigations (VII) Visible Imaging System (VIS) on board the NASA Polar spacecraft.
