Sentinel-2C is ready for launch! The new satellite will soon join its Copernicus Sentinel-2 family in orbit – where it will continue to provide detailed views of Earth’s land and coastal waters.
The mission is based on a constellation of two identical satellites: Sentinel-2A and Sentinel-2B. The constellation was originally designed to monitor land surfaces – but its scope has since expanded.
It now covers a wide range of applications including deforestation, water quality, monitoring natural disasters, methane emissions and much more.
Sentinel-2C, once in orbit, will replace the Sentinel-2A unit – prolonging the life of the Sentinel-2 mission –

Solar Orbiter shows how solar wind gets a magnetic push

ESA’s Solar Orbiter spacecraft has provided crucial data to answer the decades-long question of where the energy comes from to heat and accelerate the solar wind. Working in tandem with NASA’s Parker Solar Probe, Solar Orbiter reveals that the energy needed to help power this outflow is coming from large fluctuations in the Sun’s magnetic field.

Blue Origin completes latest space tourism flight successfully

Blue Origin flew its latest group of six thrill-seekers to the edge of space and back again Thursday, including the youngest-ever woman to complete the feat.
Mission NS-26 marked the eighth human spaceflight for the company, founded by Jeff Bezos, as it presses ahead in the emerging suborbital tourism market.
Karsen Kitchen, a 21-year-old senior at the University of North Carolina at Chapel Hill, became the youngest woman ever to cross the Karman Line, the internationally recognized boundary marking the edge of space, 100 kilometers (62 miles) above the Earth's surface.
Blue Origin's small New Shepard rocket blasted off at 8:00 am local time (1300 GMT) from the company's Launch Site One base in west Texas.
After liftoff, the sleek and spacious capsule separated from its booster, which boasts zero carbon emissions, before the rocket performed a precise vertical landing.
International consortium with NASA reveals hidden impact of spaceflight on gut health
Thursday, 29 August 2024 14:00 Write a comment
Scientists have uncovered how spaceflight profoundly alters the gut microbiome, revealing previously unknown effects on host physiology that could shape the future of long-duration space missions.
Led by University College Dublin (UCD) and McGill University, Canada, in collaboration with NASA and an international consortium, the research offers the most detailed profile to date of how space travel impacts the gut microbes we carry into space.
Published in npj Biofilms and Microbiomes, the study used advanced genetic technologies to examine changes in the gut microbiome, colons, and livers of mice aboard the International Space Station (ISS) over three months.
The findings reveal significant shifts in specific bacteria and corresponding changes in host gene expression associated with immune and metabolic dysfunction commonly observed in space, offering new insights into how these changes may affect astronaut physiology during extended missions.
Dr. Emmanuel Gonzalez, McGill University, and first author of the study, said, "Spaceflight extensively alters astronaut physiology, yet many underlying factors remain a mystery.
