Tents for Industry Space Days Venus: The trouble with sending people there
Friday, 30 September 2022 14:27 Write a comment
Venus, often called Earth's "evil twin" planet, formed closer to the sun and has since evolved quite differently from our own planet. It has a "runaway" greenhouse effect (meaning heat is completely trapped), a thick carbon-dioxide-rich atmosphere, no magnetic field and a surface hot enough to melt lead.
Several uncrewed scientific missions will study how and why that happened in the next decade. But now some scientists want to send a crewed mission there as well for a flyby. Is that a good idea?
With a slightly smaller diameter than Earth, Venus orbits closer to the sun. This means that any water on the surface would have evaporated shortly after its formation, starting its greenhouse effect. Early and sustained volcanic eruptions created lava plains and increased the carbon dioxide in the atmosphere—starting the runaway greenhouse effect, which increased the temperature from just a little higher than Earth's to its current high value of 475°C.
While the Venus year is shorter than ours (225 days), its rotation is very slow (243 days) and "retrograde"—the other way round to Earth. The slow rotation is related to a lack of magnetic field, resulting in a continuing loss of atmosphere.

Satellite Vu signs SpaceX launch contract to deploy thermal monitoring capabilities
Friday, 30 September 2022 10:17 Write a comment
British Earth Observation company, Satellite Vu has signed a second SpaceX launch contract for their second satellite, doubling their thermal data collection capacity, faster than planned, amidst rising climate concerns.
The deal will see Satellite Vu's unique Mid-wave Infrared (MWIR) imaging satellite launched into Sun-synchronous orbit (SSO) aboard a Falcon 9 rocket in early 2024. The sa Asteroid that formed Vredefort crater bigger than previously believed

About two billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa. The impactor-most likely an asteroid-formed what is today the biggest crater on our planet.
Scientists have widely accepted, based on previous research, that the impact structure, known as the Vredefort crater, was formed by an object about 15 kilo Once upon a rover

Once upon a time - early 2013 - there was a small corner room in the Flight Projects building at JPL where the walls and windows were coated in pages and pages of paper. These pages contained the facts and arguments being assembled by the Mars 2020 Science Definition Team, who were asking: what must the next rover to Mars do?
We rearranged those pages over and over during the next few mont China's Mars rover reveals more of subsurface

What does the subsurface of Mars' northern lowlands have in common with a French mille crepe cake? They both consist of a number of layers, according to the latest findings by China's Zhurong Mars rover published in the journal Nature on Monday.
The discovery showed that the evolution of the Martian surface environment is more varied and complex than previously anticipated, experts said. L Lunar glass shows Moon asteroid impacts mirrored on Earth

A Curtin-led research team has found asteroid impacts on the Moon millions of years ago coincided precisely with some of the largest meteorite impacts on Earth, such as the one that wiped out the dinosaurs.
The study also found that major impact events on Earth were not stand-alone events, but were accompanied by a series of smaller impacts, shedding new light on asteroid dynamics in the i
