Ward, J. 2019 This is a copy of PDS3 product A15A-L-HFE-3-THERMAL-CONDUCTIVITY-V1.0:A15_HFE_P2_4-201201. It contains data from 1971 to 1974 for the upper ring bridge of Apollo 15 probe 2, restored from tapes provided by personnel at Lamont Observatory to the NSSDC. Programs included in urn:nasa:pds:a15_17_hfe_concatenated:document_source can operate on it to generate products in a15_17_hfe_concatenated:data. Note that this label's time coordinates may differ slightly from time coordinates in LID_TBD:data due to differences in fractional leap second handling. 2020-02-13 1.0 Initial version. 1971-08-02T13:42:18Z 1974-12-27T12:54:17Z Apollo 15 Mission urn:nasa:pds:context:investigation:mission.apollo_15 data_to_investigation APOLLO 15 LUNAR SURFACE EXPERIMENTS PACKAGE Spacecraft urn:nasa:pds:context:instrument_host:spacecraft.a15a is_instrument_host HEAT FLOW EXPERIMENT Instrument urn:nasa:pds:context:instrument:hfe.a15a is_instrument Moon Satellite urn:nasa:pds:context:target:satellite.earth.moon data_to_target A15A-L-HFE-3-THERMAL-CONDUCTIVITY-V1.0:A15_HFE_P2_4-201201 data_to_derived_source_product GEO a15_hfe_p2_4.tab 28704 598
