WIND SPACECRAFT

Comprehensive Solar Wind Laboratory for Long-Term Solar Wind Measurements



Wind is a spin stabilized spacecraft launched with a Delta II rock on November 1, 1994. After several orbits through the magnetosphere, Wind was placed in a halo orbit around the L1 Lagrange point -- more than 200 Re upstream of Earth -- in early 2004 to observe the unperturbed solar wind that is about to impact the magnetosphere of Earth. Wind, together with Geotail, Polar, SoHO and Cluster, constitute a cooperative scientific satellite project designated the International Solar Terrestrial Physics (ISTP) program that aims at gaining improved understanding of the physics of solar terrestrial relations.


The primary science objectives of the Wind mission are:
  • Provide complete plasma, energetic particle and magnetic field for magnetospheric and ionospheric studies.
  • Investigate basic plasma processes occurring in the near-Earth solar wind.
  • Provide baseline, 1 AU, ecliptic plane observations for inner and outer heliospheric missions.

AWARDS



Engineering Operations Award [September, 2015]: The Wind Operations Team, NASA Goddard Space Flight Center, Greenbelt, Maryland, received the AIAA Space Operations & Support Award on September 2, 2015. The award honors the team's "exceptional ingenuity and personal sacrifice in the recovery of NASA's Wind spacecraft." Jacqueline Snell - engineering manager for Wind, Geotail, and ACE Missions - will accept the award on behalf of the team. [Award Details]

Group Achievement Award [June, 2015]: The Wind Operations Team, NASA Goddard Space Flight Center, Greenbelt, Maryland, received the NASA Group Achievement Award for recovery of the Wind spacecraft's command and attitude processor. [Award Details]

New Data Products



New 3DP Data Set:
2016 The 3DP electron electrostatic analyzer (ESA) data has recently been re-examined to produce updated velocity moments for the entire electron distribution. The data can be found at CDAWeb (with label wi_emfits_e0_3dp) currently covering Jan. 1, 1995 to Dec. 31, 2004. The data was produced for periods when the Wind spacecraft was in the solar wind, thus periods in the magnetosphere have not been processed.

New WAVES Data Set:
2016 The WAVES time domain sampler (TDS) receiver, which measures high frequency electric and magnetic fluctuations, also observes the plasma cloud produced by dust impacts on the spacecraft body. David Malaspina (PI) and Lynn B. Wilson III (Co-I) recently scanned through and compiled a list of all the dust impacts observed by the TDS receiver between Jan. 1, 1995 and Jan. 1, 2016 called the dust impact database. The data set was publicly released and is availble at CDAWeb.

New SWE Ion Faraday Cup Data Sets:
2016 Newly procesed Wind SWE Ion Faraday Cup (FCs) data sets are available on the Data section of this page. The SWE Ion reduced velocity distribution function data sets are availble at CDAWeb.

2017 New graphical user interface (GUI) software release for analyzing the SWE FC data sets can be found at Janus.

New EPACT Data Sets:
2018 Newly procesed Wind EPACT-STEP data sets are available at CDAWeb.

2016 Newly procesed Wind EPACT-LEMT data sets are available on the Data section of this page. The data are also availble at CDAWeb and VEPO.

2016 New release of the 20 MeV proton channel from the EPACT-APE detector are available at VEPO and now at CDAWeb.

New KONUS Data Set:
2018 Data for all solar flares registered by the KONUS instrument in the triggered mode are available on-line via the Solar Flare Database. The database contains energy spectra and detector response matrices in FITS format as well as light curves in G1, G2 and G3 channels in ASCII and IDL SAV formats for solar flares detected in the triggered mode. New solar observations will be added to the database as soon as they arrive.
