Coordinated Data Analysis Web (CDAWeb)CDAWeb contains selected public non-solar heliophysics data from current and past heliophysics missions and projects. Many datasets from current missions are updated regularly (even daily), including reprocessing older time periods, and SPDF only preserves the latest version. To find all of the public data and documents archived by the SPDF, see the SPDF archive. To search for additional heliophysics data products, check the heliophysics data portal. REMINDER: CDAWeb offers CREATION of subset/supersets of data sets (by date and variables), CREATION of uniformly time binned data, PLOTS in PDF, PS and PNG formatted files, MOVIES of specific image sequences, ON-THE-FLY Inventory plots, ADJUSTABLE height time/spectrogram plots, plus many more options...February 2023: ALL SPDF systems/services (CDAWeb, SSCWeb, OMNIWeb, CDF, etc.) will be unavailable from 10:30am - 12:00pm EST Thursday February 9th. Please plan your use of the systems/services accordingly.NOTICE: January 2023: The Level 3 Heavy Ion Sensor (HIS) composition data (SOLO_L3_SWA-HIS-COMP-10MIN) has been added to the archive and the system.NOTICE: January 2023: The default plotting height has been changed to twice the standard height (see the "CHANGE the Y-axis height" option to modify the setting).NOTICE: November 2022: The PSP data have been extended up to August 2022, covering the rest of Orbit 12 and part of the inbound leg of Orbit 13. EPI-Lo calculations have been updated affecting Quadrant 1 (look directions 20-39) fluxes and count rates. Please check the PSP inventory plot and annual inventory plots for details.

The first mystery to be addressed by a solar probe emerged with the 1869 total solar eclipse, when American astronomers Charles Augustus Young and William Harkness observed a novel green emission line with a wavelength of 530.3 nanometers in the solar corona. At the time, scientists suspected they were observing the chemical fingerprint of an undiscovered element; they dubbed it Coronium. Advances in laboratory spectroscopy led to the surprising discovery in the 1940s (Edlén 1941) that the spectral lines came from ionized iron, heated to such an extreme temperature that it had lost 13 of its 26 electrons.
Before 2008, the solar probe concept underwent five major design revisions. Each addressed the engineering challenges described above in different ways, often resolving problems in earlier iterations and sometimes creating new ones.
Solar Probe+ employed two solar arrays. Primary arrays would be used outside .25 AU and then, as the probe approached the Sun, retract behind the heat shield, when smaller secondary arrays would deploy. These secondary arrays would be actively cooled by a closed-loop system of liquid ammonia.
Since its launch August 12, 2018, Parker Solar Probe has not disappointed. On the very first orbit, during solar minimum conditions, the probe returned measurements that shed new light on the Sun and its atmosphere. Critical data provided tantalizing clues as to the cause of coronal heating and powering of solar wind. 2ff7e9595c
