Remote sensing satellite to be used for land use surveys, urban planning, road network design, crop estimation and disaster prevention/mitigation. Orbit notes: https://www.zarya.info/Diaries/Launches/Launches.php?year=2019#066 An unspecified issue on Oct 2 caused launch postponement from Oct 3.


ISS EVA
Quest Airlock, US Segment, ISS
2019 Oct 6, 11:39 UTC
First in set of five planned, related spacewalks. EVA tasks involve replacing batteries on the far end of the station’s port truss. Twelve existing nickel-hydrogen batteries will be upgraded by using six more powerful lithium-ion batteries transported to the station aboard Kounotori 8. EVA continues overall upgrade of the ISS power system that began with similar battery replacement during spacewalks during 2017 Jan. Participants - Christina Koch and Andrew Morgan, expected duration around 6.5 hrs. EVA began eleven minutes ahead of schedule. All tasks were completed before the 4 hr 30 min point so time was spent on 'get ahead' tasks prior to the next planned EVA. EVA ended at 18:40 UTC after 6hr 1 min.

Eutelsat 5 West B & MEV-1
Proton-M + Briz-M, Baikonur
2019 Oct 9, 10:17 UTC
Precise launch time - 10:17:56 UTC, Eutelsat separation - Oct 10 at 01:53 UTC, MEV-1 separation Oct 10 at 02:11 UTC. Eutelsat 5 West A Comsat to join Eutelsat 5 West A at 5° west longitude and eventually take over its functions. Coverage is aimed at France, Italy and Algeria. Satellite includes EGNOS (European Geostationary Navigation Overlay Service) to improve the precision of ESA's Galileo navigation system for users needing very precise position information. https://www.eutelsat.com/en/satellites/eutelsat-5-west.html MEV--1 Northrop Grumman Mission Extension Vehicle 1 - planned to rendezvous and attach itself to the Intelsat 901 comsat at 29° west and take over its pointing and station-keeping functions in order to extend its on-orbit life by five years. May then move to another satellite. https://www.northropgrumman.com/Capabilities/SpaceLogistics/Documents/MEV_Factsheet.pdf http://www.intelsat.com/news/blog/intelsats-journey-with-the-first-mission-extension-vehicle/ Postponed from Sep 30 because, on Sep 24, prelaunch checks detected an incorrect electrical or electronic connection between the Briz-M stage and the separation system for the MEV-1 satellite.
