SUMMARY:Biomass : ESA's forest mission
DESCRIPTION:Biomass is an Earth observing satellite planned for launch by the European Space Agency (ESA) on 29 April 2025 from Kourou\, French Guiana on a Vega C launch vehicle\, the mission will provide the first comprehensive measurements of global forest biomass. \nIt is meant to last for five years\, monitoring at least eight growth cycles in the world’s forests. The Biomass satellite is part of ESA’s Living Planet Programme\, which consists of Earth observation missions. Its initial launch date was set to 2020\, but that has since been delayed to 2025. The entire cost of the mission was placed at around 400 million euros. The main scientific instrument aboard Biomass will be a synthetic aperture radar (SAR) operating at 435 MHz. The satellite will measure 10 x 12 x 20m\, weigh around 1.2 tonnes and it is set to orbit the Earth at an altitude of 666 km. All devices for assembly of the satellite structure\, including vertical transport equipment\, assembly and disassembly of satellite panels\, assembly and disassembly of the Synthetic Aperture Radar are done by the Spanish company SENER. \nLinks:\nBiomass – ESA \n#ForestDay #IntlForestDay Day of Forests / Dag van het Bos 2025 (TV FAO webcast)

SUMMARY:DNA Day 2026
DESCRIPTION:DNA Day is a United States holiday celebrated on April 25\, it commemorates the day in 1953 when James Watson\, Francis Crick\, Maurice Wilkins\, Rosalind Franklin and colleagues published papers in the journal Nature on the structure of DNA. \nFurthermore\, in early April 2003 it was declared that the Human Genome Project was very close to complete\, and “the remaining tiny gaps were considered too costly to fill.” In the United States\, DNA Day was first celebrated on April 25\, 2003\, by proclamation of both the Senate and the House of Representatives. However\, they only declared a one-time celebration\, not an annual holiday. Every year from 2003 onward\, annual DNA Day celebrations have been organized by the National Human Genome Research Institute (NHGRI)\, starting as early as April 23 in 2010\, April 15 in 2011 and April 20 in 2012. April 25 has since been declared “International DNA Day” and “World DNA Day” by several groups. Genealogical DNA testing companies and genetic genealogy publishers run annual sales around DNA Day\, seeking interest from the public and promoting their services. \nLinks:\nDNA Day \nESHG DNA Day Essay & Video Contest
