ESA
The European Space Agency is an intergovernmental organization founded by European nations to plan and implement European space programs. Its activities span research and engineering in satellites, space probes, and launch vehicles across a broad range of space disciplines.

The Mars Sample Return (MSR) program faces adjustments due to budget overruns and schedule delays.
The core obstacle to the automotive-grade transplantation of space-grade technology lies in the mismatch of certification standards: spacecraft components follow NASA or ESA standards, while automotive parts must pass standards such as the AEC-Q series and ISO 26262 functional safety, which require million-unit mass-production consistency and a service life of more than ten years.
MQM classifies, counts, and weights errors by error type (such as accuracy and fluency) and severity (such as minor and major), while ESA requires annotators to precisely circle the text spans corresponding to errors.
A new paper systematically tested LLM performance on the two mainstream approaches to machine translation quality evaluation, multidimensional quality metrics (MQM) and error span annotation (ESA), concluding that both humans and models face challenges.
MQM and ESA abandon reliance on reference translations and directly annotate errors in the translation, so they are regarded as approaches closer to human judgment, but at the cost of sharply rising annotation costs.
NASA's Mars Sample Return (MSR) mission has been declared finished/cancelled.
The European Space Agency had relied on Russia's Soyuz spacecraft to transport astronauts, and after the outbreak of the Ukraine war in 2022, European-Russian space cooperation was significantly curtailed.
The target customers of the Nyx spacecraft include the European Space Agency (ESA), NASA, and commercial space station operators.
