EnMAP - Environmental Mapping ProgramEnMAP is a future - first German optical - earth observation satellite mission. The satellite will provide valuable, high-quality scientific data with 232 spectral bands from 420 nm to 2450 nm and a ground resolution of 30 x 30 m².Primary mission goal is the measuring and analyzing a wide range of numerous ecosystem parameters which describe vital processes on the earth’s surface relating to agriculture, forestry, soil and geological environments, as well as coastal zones and inland waters. EnMAP data will serve to measure and model key dynamic ecosystem processes and will make a significant contribution to comprehension of the complex system "Earth".The mission will be realized in a co-operation between GFZ, Kayser-Threde, OHB and DLR. GSOC will operate the satellite during LEOP, commissioning phase and routine operations.Launch Date planned: 2017Orbit Altitude: 653 km Orbit Inclination: 97.96°Masse: 980 kgDimensions: 3,1 m × 2,0 m × 1,7 mLaunch Site: Sriharikota, IndiaLauncher: PSLV (Polar Satellite Launch Vehicle)Mission Duration: > 5 yearsControl Center: DLR / GSOCLINK: http://www.dlr.de/rb/en/desktopdefault.aspx/tabid-6815/11182_read-25528/
PSLV version is currently unknown but EnMAP is believed to be flying as a passenger on a 2017 SPOT flight.

EnMAP slips to "end of 2021":https://www.ohb.de/en/news/2020/instrument-for-german-environmental-satellite-enmap-performing-well-in-test-campaign/
The hyperspectral instrument (HSI) for the EnMAP satellite will be spending the next few weeks in IABG’s space testing center to undergo the environmental testing campaign to determine whether it will be able to survive the conditions prevailing in space [vibrational?, acoustic, thermal-vacuum, electromagnetic compatibility].Following the completion of the environmental test campaign and after the EnMAP instrument has returned to OHB’s space center “Optics & Science” in Oberpfaffenhofen near Munich, integration on the platform, known as the satellite bus, will commence. The EnMAP satellite will then start taking shape. At the end of 2021, the “environmental scout” is to be launched to its destination in a sun-synchronous orbit around the Earth at an altitude of around 640 kilometers. The mission is to have a duration of five years.

It will acquire high quality hyperspectral image data with 230 spectral channels in the solar-reflectance range on a frequent basis with high geometric resolution. The major objectives of the mission are to measure, derive, and analyze numerous diagnostic parameters which describe vital processes on the earth’s surface relating to agriculture, forestry, soil and geological environments, as well as coastal zones and inland waters. During operations the mission will provide information about the status of different ecosystems and their response to natural or man-made changes in the environment. The mission management is led by the Space Agency of the German Aerospace Center (DLR). The scientific aspects of the mission are covered by the German Research Centre for Geosciences (GFZ). The OHB-System AG is responsible for the development, production, and launch of the satellite. The establishment and operation of the ground segment is performed by the DLR entities Earth Observation Center (EOC) and Space Operations and Astronaut Training (RB) .

Any chance this could be launching on a Transporter mission?
Quote from: scr00chy on 08/22/2021 11:16 amAny chance this could be launching on a Transporter mission?It has small thrusters, and the operational altitude is a bit high for a normal Transporter deployment, so it may depend on how close to the operational orbit they're willing to accept. I would guess they'd try for some sort of rideshare even if it isn't a Transporter mission.

The hyperspectral satellite EnMAP (Environmental Mapping and Analysis Program) has reached the next milestone and successfully completed the environmental tests at the IABG test center in Ottobrunn, Bavaria. Further functional tests at the OHB company headquarters in Bremen, where the satellite is now being prepared for departure towards the launch site, have now comprehensively confirmed the functionality of the satellite. This means that the satellite is ready for the ride into space! EnMAP is intended to provide new types of data sets on the state of the ecosystem on the land surface and its changes. In April 2022, the “environmental observer” is to set off on a Falcon 9 rocket from SpaceX for its sun-synchronous earth orbit at an altitude of around 650 kilometers.

You want to know What (co-manifests, Transporter) and How (RTLS? ASDS?) but I want to know When, what time of day?According to the website linked above, EnMap is a hyperspectral sensor picking up reflected solar radiation in the visible and short-wave Infrared spectral bands. It probably wants to fly over land at mid morning, like high resolution imaging satellites, when the light is good but the cloud cover minimum. With Florida near middle of the distribution of land masses vs latitude, and with the orbit only slightly beyond truly polar, that puts launch maybe an hour before the complimentary point, or around 9 PM solar time. It’s not obvious whether this would change with Daylight Savings Time. So it could launch shortly after sunset, like this week’s launch of CSG-2.
No matter what time of day the launch’ll be, the profile will be RTLS. I guarantee that.
