A defunct Russian satellite and a spent Chinese rocket just floating around high over Earth could smash into each other within a few days, potentially creating a big mess in orbit with potentially dire long-term consequences.
LeoLabs, which tracks space debris, put out the alert on Tuesday warning that the two large hunks of junk will come within 25 meters of each other and have up to a twenty percent chance of colliding Thursday evening.
That’s considered way too close for comfort by space standards. The two objects have a combined mass of 2,800 kilograms and if they were to smash into each other, the “conjunction” could create thousands of new pieces of space junk that would put actual functioning satellites at risk.
Two Yale University researchers have found a potential shortcut in sampling Venus’ ancient surface. Instead of sending a probe on a costly and extraordinarily challenging Venus sample return mission, they propose simply finding a Venusian meteorite on our own Moon.
There’s never been a bona fide detection of a Venusian meteorite on Earth. For one reason, that’s because in the last several hundred million years at least, Venus’ atmospheric pressures have been so intense that even a catastrophic impactor could not dislodge any Venusian rocks into space.
But before Venus underwent a runaway greenhouse and morphed into the climatic hellhole it is today, it may have had liquid water oceans as late as 700
At its Battery Day event, Tesla unveiled its new 4680 battery cell developed in-house and the manufacturing process behind it.
The highly anticipated presentation went deep into details about all the different pieces of material science, design, and manufacturing innovations that it took to deliver the masterpiece of a puzzle that the automaker needed to put together to reduce battery costs by more than 50% in just 3 years…
Over the last few years, Tesla has been making a lot of moves related to batteries.
We are talking about buying companies like Maxwell and Hibar, and applying for patents on new technology, like a tabless battery cell and a cell to pack design.
While all these moves were mostly evaluated on their own merits, it wasn’t clear how all those things would fit together.
That’s exactly what Tesla demonstrated at its Battery Day.
