ISAS has lost contact with Akatsuki after an operation in late April due to an extended period of low attitude stability control mode, and is currently making efforts to reestablish communication with the spacecraft.

We will inform you about future plans once they are fixed. Thank you for your warm support.

That's 30-100kg a day so still a few days to print one engine...

Heaven-sent EarthCARE to study clouds and climate

Airbus-built ESA-JAXA climate satellite successfully launched EarthCARE


Friedrichshafen, 29 May 2024 – The Airbus-built EarthCARE climate monitoring satellite has been successfully launched from Vandenberg military base, California. EarthCARE (Earth Cloud Aerosol and Radiation Explorer) is a joint undertaking between the European and Japanese Space Agencies (ESA and JAXA). The satellite will examine the role clouds and aerosols (tiny atmospheric particles) play in reflecting solar radiation back into space (i.e. cooling down the atmosphere) as well as in trapping infrared radiation emitted from the Earth’s surface (i.e. heating up the atmosphere).

“EarthCARE is ESA’s largest and most complex Earth Explorer spacecraft – a flagship mission whose data will help improve the accuracy and reliability of climate and numerical weather prediction models,” said Alain Fauré, Head of Space Systems at Airbus. “International cooperation was key with more than 200 research institutes and 45 companies across Europe working hand in hand to deliver this spacecraft.”

EarthCARE will draw up vertical profiles of natural and human-made aerosols, register the distribution of water droplets and ice crystals and how they are transported in clouds, and provide essential input to improve the modelling of the warming climate and weather forecasting. Aerosols influence the life cycle of clouds, and so contribute indirectly to how they give off radiation – measuring them will give a better understanding of Earth’s energy budget.

Instrumental cooperation: one mission, two agencies, four instruments

The spacecraft was developed, built and tested with the involvement of experts from 15 European countries as well as Japan and Canada, under the leadership of Airbus, in Friedrichshafen, Germany.

Four instruments EarthCare

The Airbus-built atmospheric lidar ATLID is one of the four instruments on the EarthCARE satellite, providing vertical profiles of aerosols and thin clouds. ATLID is the second spaceborne ultraviolet lidar from Europe following Aeolus’, making Airbus a worldwide specialist in spaceborne lidars.

The satellite also includes a Broad-Band Radiometer developed by ESA through European industry, a Multi-Spectral Imager developed by Airbus’ subsidiary Surrey Satellite Technology Limited and a Cloud Profiling Radar developed by JAXA.

This unique combination of instruments will allow scientists for the first time to directly assess the role of clouds and aerosols on Earth’s radiation budget with one integrated satellite system thereby reducing current uncertainties.

EarthCARE will circle Earth in a Sun-synchronous 400 km polar orbit crossing the equator in the early afternoon to optimise daylight conditions. Weighing 2.3 tonnes, and measuring 18 metres long, once its solar panel and CPR instrument are deployed EarthCARE will be on duty for at least 3 years.

NASA is already working on a 3d printed RS-25 nozzle and combustion chamber, I found an interesting video about it:

If NASA is already there, I'm sure SpaceX is already doing the same with the turbopumps.

To me the most insidious claim about SpaceX in the NYT article is not directly about rideshare:

Quote
Mr. Ellis of Relativity Space said SpaceX had made explicit and repeated efforts to limit the growth of his business.
“Every single funding round that was done once we started to become a larger company, and every single customer deal we have signed, has been followed with a swift and large number of outreach calls from SpaceX to all of those entities berating them for doing things with us,” he said. “This is not theoretical.”

Berating people is probably not in SpaceX's best interests even if its interests are self-centered. SpaceX should remind its people not to do this sort of thing.
