No Starlinks on this launch, as was also the case for Transporter-3.

I think that’s EnMAP on the very top of the dispenser.

ASOG is heading out.

[Edit March 28: ASDS for Axiom-1 instead?]

Cluster 4 satellites are being prepared for launch aboard a SpaceX Falcon 9 rocket from the Cape Canaveral later this week. Pictured here are Ryan Fielder and Farid Juman integrating one of our Cluster 4 satellites to the adaptor ring.

DLR Press Release, 30 March 2022

German EnMAP satellite ready for launch - Environmental data for researchers worldwide

The Environmental Mapping and Analysis Program (EnMAP) satellite sees the world very differently from the way the people who live there do. The German environmental satellite measures the solar radiation that is reflected by Earth's surface. EnMAP not only captures visible light, but also short-wave infrared. These data allow precise conclusions to be drawn about conditions and changes on Earth's surface. The German Space Agency at DLR in Bonn is leading this unique mission on behalf of the German Federal Ministry for Economic Affairs and Climate Action. Multiple institutes and facilities at the German Aerospace Center (Deutsches Zentrum fuer Luft- und Raumfahrt; DLR) are involved in the preparations for and operation of the mission, as well as scientifically evaluating the data.

The EnMAP hyperspectral satellite is scheduled to lift off from NASA's Kennedy Space Center in the USA on Friday 1 April 2022 aboard a Falcon 9 rocket from the US space company SpaceX. The German Space Operations Center (GSOC) in Oberpfaffenhofen will be responsible for satellite operations on behalf of the German Space Agency at DLR. GSOC employees have been conducting space missions from the centre's control rooms since 1969. GSOC has now successfully operated more than 70 missions, including the TerraSAR-X and TanDEM-X satellite system, which has been observing Earth using radar since 2007. The resulting data can be used for purposes including the generation of location maps for disaster management in the event of flooding and earthquakes. EnMAP data will help to address current issues in the fields of environment, agriculture, land use, water quality and geology.

242 channels go well beyond red, green and blue

DLR's Earth Observation Center (EOC) will be responsible for processing EnMAP data: "We receive and process the mission data, before making them available to scientists worldwide free of charge via a web portal," says Guenter Strunz of the German Remote Sensing Data Center (DFD). The satellite transmits the data to DLR's receiving stations in Neustrelitz (Germany) and Inuvik (Canada). These are then calibrated, corrected and displayed as image maps. "The EnMAP data are not images in the conventional sense, but spectral measurements," adds Strunz. In visible light, all colours can be generated from the three primary colours red, green and blue. Like human eyes, conventional cameras only perceive light in the three primary colours: red, green and blue. A hyperspectral system like EnMAP distinguishes between a wide variety of hues, even in parts of the infrared spectrum, which are invisible to the human eye. Overall, the satellite maps Earth’s surface in spectra divided over 242 channels.

Disruptive atmospheric influences corrected

The processing of the data enables meaningful results. The last standardised processing step at EOC is atmospheric correction. "The reflected signal is altered by the atmosphere, so the effects of things such as water vapour and aerosols have to be corrected so that we only get the exact reflectance at the Earth's surface," says Peter Reinartz of the DLR Remote Sensing Technology Institute (IMF), which forms the EOC together with the DFD. "We can establish physical, chemical and biological soil parameters on the basis of the results. We might want to find out how much carbon the soil has absorbed, for example, or whether methane is leaking from a pipeline."

DLR's Center for Satellite-based Crisis Information (ZKI) will also use the data from EnMAP. The ZKI is involved in global networks such as the International Charter Space and Major Disasters. In the event of major natural disasters, the ZKI obtains and analyses Earth observation data with the aim of providing up-to-date information on the situation for public authorities and emergency services. This situational information was used, for instance, during the flooding in the German regions of North Rhine-Westphalia and Rhineland-Palatinate in July 2021.

Technology for the satellite's 'eye'

The DLR Institute of Optical Sensor Systems in Berlin was commissioned by OHB System AG to develop one of EnMAP's focal plane (or 'eye'). The focal plane is comparable to the retina of a human eye. In the case of optical satellites, the light arrives at the focal plane, is converted into electrical signals and transmitted onwards. The module for the visible and near-infrared range (VNIR for short) is only approximately 12 by 12 by 4 centimetres in size and weighs 1050 grams. The entire satellite weighs 950 kilograms. "The focal plane that the Institute developed for EnMAP is the latest in a long line of successful projects," says Institute Director Heinz-Wilhelm Huebers. This also includes the DLR-developed DESIS hyperspectral instrument on the International Space Station (ISS), which provides data on the state of vegetation on Earth. Like DESIS, the focal plane of EnMAP also facilitates technology transfer.

EnMAP – the German environmental mission and its partners

The EnMAP environmental mission is managed by the German Space Agency at DLR in Bonn on behalf of the Federal Ministry for Economic Affairs and Climate Action (BMWK). OHB System AG was commissioned to develop and build the satellite and its hyperspectral instrument. The German Research Centre for Geosciences (Deutsche GeoForschungsZentrum; GFZ) in Potsdam is the scientific lead for the study.

Three DLR institutes and facilities have been commissioned to set up and operate the ground segment. The German Space Operations Center in Oberpfaffenhofen will conduct and monitor satellite operations, while the German Remote Sensing Data Center and the DLR Remote Sensing Technology Institute will archive, process and validate the received satellite data and make them accessible to users in the scientific community. Companies and public authorities will also be able to view the data and use them to prepare future services. The use of EnMAP hyperspectral data by universities and scientific institutions and the development of special applications will be supported by BMWK funding programmes.

I know, that's why I said "or".

Anyway, it's BRO-7 that's flying with SpaceX: https://unseenlabs.space/launch/

SpaceX is targeting Friday, April 1 for a Falcon 9 launch of Transporter-4 to a sun-synchronous orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The launch window opens at 12:24 p.m. ET, or 16:24 UTC. Falcon 9 will fly on a southern trajectory along Florida’s eastern coast and may be visible from the ground.

Falcon 9’s first stage booster previously launched Crew-1, Crew-2, SXM-8, CRS-23, IXPE, and one Starlink mission (B1061.7). Following stage separation, SpaceX will land Falcon 9’s first stage on the Just Read the Instructions droneship stationed in the Atlantic Ocean.

Transporter-4 is SpaceX’s fourth dedicated smallsat rideshare mission. On this flight are 40 spacecraft, including CubeSats, microsats, picosats, non-deploying hosted payloads, and an orbital transfer vehicle carrying spacecraft to be deployed at a later time.
