v2.5.0 This major update includes an extension of re-entry emissions back to 1957. Re-entries Only checking missing stages with an apogee of >100 km. Skipping objects from explosions. Not cross-checking against DISCOSweb or Aerospace Corp. Not including objects from failed launches pre-1957. Not checking for missing fairings. Not updating timings for re-entries with missing timings. Minor changes to re-entry mass for 2020-2024 from updates to rocket stage masses. Refactoring Now loading all information for launches and rockets using GCAT, and merging into single files across the space age. This has updated the timings, locations, and launch site names, but this won't affect the emissions. The coordinate changes are only small and will be in the same grid box. The names and variants are slightly different in GCAT, so the new names needed to be added to launch event altitudes and update_rocket_launch_data.py script. GCAT also uses slightly different designations for failed launches, which are now accounted for. Removed lat lon from re-entry outputs, as these aren't even used on the website. Bug fixes to launch emissions Changing the names to the GCAT names uncovered missing launch event altitudes and incorrect propellant data which was fixed. Overall there were changes in emissions for: Changes pre-2020: Pegasus XL/HAPS Minotaur I Proton-M/Briz-M, Protom-M/DM-2 PSLV CA H-IIA 202 1 variant Minotaur IV variants Soyuz ST-A/B Fregat Epsilon variants. Atlas V XXX 'C' variants Vega 1 variant H-IIA 204 2 variant Delta 4H A variant GSLV Mk III a variant Electron GSLV Mk II b/c variant LVM3 Ariane 5ECA+ variant Antares 230+ variant CZ 2C and variants CZ 3B/C and variants Minotaur I/IV and associated variants Epsilon. Changes post-2020: CZ 2C and variants CZ 3B/C and variants Minotaur-I CZ 7A (above only) CZ 8 Shuang Quxian 1 3 variant 2023-201 Soyuz-2-1B has changed to Soyuz-2-1A in GCAT 2024-240 Chang Zheng 5/YZ-2 has changed to Chang Zheng 5B/YZ-2. New Starship launches 2024-U01, 2024-U03, 2024-U04, 2024-U06 Kairos and Ariane 62 data is now from GCAT so the emissions are slightly different. GCAT only has Fregat, no Fregat-M or Fregat-MT (this only affects the third stage which is above the model).
