Planet and Carbon Mapper to fly SWIR Tanager

SAN FRANCISCO – Planet is developing a new version of its Tanager spacecraft with enhanced capability to detect and monitor methane and trace-gas emissions. In contrast to the hyperspectral Tanager-1, launched in 2024, the new satellite will “solely target shortwave infrared (SWIR) light” and provide “five times the areas coverage,” Planet said in an April […] The post Planet and Carbon Mapper to fly SWIR Tanager appeared first on SpaceNews.

America needs a space alliance

Right before the historic Artemis 2 mission, retired astronaut and former Navy captain Scott Kelly and India’s Gaganyaan astronauts, speaking in New Delhi, entertained the concept of a “World Space Organization” to guide humanity’s future beyond Earth. Kelly joked that this could be the start to a Starfleet, in reference to Star Trek’s central spacefaring […] The post America needs a space alliance appeared first on SpaceNews.

SpaceComputer to conduct on-orbit test of secure computing infrastructure

SAN FRANCISCO — SpaceComputer, a Singapore-based startup developing distributed computing infrastructure, is preparing to test its hardware and software in orbit later this year. The startup’s first product, Space Fabric, is a hardware and software architecture with secure and physically isolated computing elements to link ground stations with satellites and enable satellites to share computing […] The post SpaceComputer to conduct on-orbit test of secure computing infrastructure appeared first on SpaceNews.

US–Indian space mission maps extreme subsidence in Mexico City

One of the most powerful radar systems ever launched into space has mapped the ground moving beneath one of the fastest subsiding capitals in the world: Mexico City. The findings show how quickly and reliably the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite can track real-time changes across Earth’s surface from orbit, unhindered by clouds or vegetation that impede optical sensors and higher-frequency radars.

New Lithium-Plasma Engine Passes Key Mars Propulsion Test

You’re on the fourth human mission to Mars, and you’re told the Odyssey spacecraft designed to take you there will be the smoothest ride you’ll ever take. It features a newly christened electric propulsion engine which was in the late stages of testing during the first three missions. The mission starts and the spacecraft travels at a crawl, and you wonder if it’s broken. A week goes by and you’re now traveling at more than 400,000 kilometers (250,000 miles) per hour, and your mind is blown as to how fast you’re going, how quickly that happened, and that this mission might be more awesome than you thought.

DAMPE satellite reveals cosmic rays share spectral break near 15 teravolts

A century after their discovery, cosmic rays—particles of extreme energy originating from the far reaches of the universe—remain a mystery to scientists. The DAMPE (Dark Matter Particle Explorer) space telescope is tackling this phenomenon, particularly investigating the role that dark matter may play in their formation. This international mission, which includes the University of Geneva (UNIGE), has made a major breakthrough by highlighting a universal feature of these particles. The results are published in the journal Nature.

How do you study something you can never step outside of?

An international team of astrophysicists has just released one of the largest cosmological datasets ever assembled. A mouthwatering 2.5 petabytes of simulated universe, freely available to researchers anywhere in the world. Built using a supercomputer and a suite of simulations called FLAMINGO, the data models how matter has evolved since the Big Bang, tracing everything from individual galaxies to the vast cosmic web that stretches across billions of light years.

What is the Most Common Type of Planet in the Galaxy?

Astronomers now believe there is at least one planet for every star in the Milky Way but new research has revealed a deeply unsettling twist in that picture. The most common planets in our Galaxy, it turns out, are almost entirely absent around the most common stars. Using data from NASA’s TESS satellite, researchers found that the small, faint stars that make up the vast majority of the Milky Way seem to host rocky super Earths in abundance, but virtually no sub Neptunes, the planet type previously thought to be plentiful. The finding doesn’t just refine existing theories of planet formation, it rewrites them.

Measurement of nuclear reactions at record-low energies opens new pathways for astrophysics research

An international research team has achieved an important milestone for astrophysics at GSI/FAIR in Darmstadt: In the CRYRING@ESR storage ring, scientists were able to measure nuclear reactions at extremely low energies for the first time, mirroring the conditions inside stars. This novel experimental approach lays the foundation for decoding the formation of elements in the universe with even greater precision in the future.
