Wind-sculpted feature on Mars is an extensive dust factory
Friday, 25 February 2022 13:50This image from ESA's Mars Express shows part of possibly the largest single source of dust on Mars: a wind-sculpted feature known as the Medusae Fossae Formation, or MFF.
The MFF is not only a veritable dust factory, but also remarkably extensive—it is the largest sedimentary deposit on the planet and stretches out discontinuously for more than 5,000 km, covering an area about the size of India. It is named for the Greek mythological Gorgon Medusa, who was able to turn those who looked into her eyes to stone, with the suffix 'fossae' being Latin for trenches or hollows.
The formation is found along the boundary between Mars' southern highlands and northern lowlands (known as the martian dichotomy), and sits between the planet's two most prominent volcanic regions (Tharsis and Elysium). It also contains the Eumenides Dorsum mountain range, the edges of which can be seen in the gentle elevation extending out of the bottom right of the frame (northeast).
ULA: Russia sanctions not expected to disrupt Atlas 5 operations
Friday, 25 February 2022 13:41United Launch Alliance said the operation of the Atlas 5 vehicle, which is powered by the Russian RD-180 engine, will not be affected by the economic sanctions imposed on Russia in response to the invasion of Ukraine
Here's what China is planning to do in space for the next five years
Friday, 25 February 2022 13:30Central planning is literately central to any communist country, though its history has mixed results. As part of that planning, bureaucrats in all parts of the government are occasionally tasked with coming up with goals and milestones for their specific part of the government. These usually take the form of a five- or 10-year plan, which is what the China National Space Agency (CNSA) released on January 28.
This is the fifth such report, with previous releases in 2000, 2006, 2011 and 2016, and the current plans for future space exploration build on the efforts of the past plans. At more than 7,500 words, the document itself is hefty but still a relatively high-level overview of what the agency hopes to achieve. Some main focal points include improving the sustainability of their rocket launches, improving their global position system, partnering with Russia on lunar exploration, maintaining and expanding the Tiangong space station, researching the underlying technology for a Mars sample return mission, and building a global partnership to build a research station on the moon.

The last day of the dinosaurs
Friday, 25 February 2022 09:50The asteroid which killed nearly all of the dinosaurs struck Earth during springtime. This conclusion was drawn by an international team of researchers after having examined thin sections, high-resolution synchrotron X-ray scans, and carbon isotope records of the bones of fishes that died less than 60 minutes after the asteroid impacted. The team presents its findings in the journal Nature.
Potential widespread effects of geoengineering on both climate and the carbon cycle
Friday, 25 February 2022 09:50Global warming poses a great threat to our society, and it will continue unless a deep and rapid reduction in greenhouse gas emissions is implemented. One alternative way to counteract some of the undesired effects of global warming is geoengineering, also referred to as solar radiation modification, or climate engineering. The basic idea of geoengineering is to cool the earth by intention

In addition to designing and building the spacecraft and telescope, Ball Aerospace is responsible for conducting system integration
Cosmic flashes pinpointed to a surprising location in space
Friday, 25 February 2022 09:50Astronomers have been surprised by the closest source of the mysterious flashes in the sky known as fast radio bursts. Precision measurements with radio telescopes reveal that the bursts are made among old stars, and in a way that no one was expecting. The source of the flashes, in nearby spiral galaxy M 81, is the closest of its kind to Earth.? Fast radio bursts are unpredictable, extreme
