Methods for automatically downloading SPICE kernels for various objects. This is essentially a library of SPICE kernels that are available online, so users don’t have go go hunting for them. If you know a kernel is out of date, and HelioPy should be using a newer kernel please let us know at https://github.com/heliopython/heliopy/issues.
These are general purpose kernels, used for most caclulations. They are all
automatically loaded if you are using the heliopy.spice module.
| Name | Identifier | Kernel URL(s) |
|---|---|---|
| Leap Second Kernel | lsk | [1] |
| Planet trajectories | planet_trajectories | [1] |
| Planet orientations | planet_orientations | [1] |
| Heliospheric frames | helio_frames | [1] |
These kernels store the actual trajectory of a body.
| Name | Identifier | Kernel URL(s) |
|---|---|---|
| Helios 1 | helios1 | [1] [2] |
| Helios 2 | helios2 | [1] |
| Juno | juno | [1] |
| Parker Solar Probe | psp | [1] [2] [3] |
| STEREO-A | stereo_a | [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] |
| STEREO-B | stereo_b | [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] |
| Ulysses | ulysses | [1] [2] |
These kernels store the predicted trajectory of a body.
Warning
No guarentee is given as to the reliability of these kernels. Newer predicted trajectories may be available, or newer reconstructued (ie. actual) trajectory files may also be available.
Use at your own risk!

heliopy.data.spice.get_kernel(name)¶Get the local location of a kernel.
If a kernel isn’t available locally, it is downloaded.
| Parameters: | name (str) – Kernel name. See Generic kernels and Reconstructed kernels for lists of available names. The name should be a string from the “Identifier” column of one of the tables. |
|---|---|
| Returns: | List of the locations of kernels that have been downloaded. |
| Return type: | list |
