This is what happens to spacecraft when they re-enter the Earth's atmosphere
Write a comment
When one of the Russian Progress resupply ships undocks from the International Space Station, timing is everything. The Progress needs to fire its engines at just the right time to instigate the deorbit burn in order for the ship to enter the atmosphere at just the right place so that its destructive re-entry occurs over the Pacific Ocean. That way, any potential surviving bits and pieces that might reach Earth will hit far away from any land masses—which are home to people, buildings, and other things we don't want to get bonked.
Last week, the timing for the Progress MS-15 cargo ship was just right, so that the astronauts/cosmonauts on board the ISS could see the ship as it broke apart and burned up in Earth's atmosphere. JAXA astronaut Soichi Noguchi shared the view on social media.
"Farewell, Progress 76P MS-15! #Russian cargo spacecraft undocked from #ISS, and successfully burned up," Noguchi tweeted, sharing a photo of the Progress' fiery demise.

Europe is recruiting astronauts: Here's what it takes to become one
Write a comment
For the first time in 11 years, the European Space Agency (Esa) is recruiting new astronauts. Applications will open on the 31 March 2021 for eight weeks, followed by a six-stage selection process to identify the next generation of European astronauts.
By 2030, humans will once again walk on the surface of the Moon, travel to Mars and potentially enjoy sub-orbital holidays. The new space era will provide enormous benefits to all of us. It will push technologies as we find ways to live sustainably beyond planet Earth, it will create exciting jobs and it will generate new socioeconomic opportunities.
Recruiting new astronauts is the first step into this new era of human space exploration. Many people may have dreamed of becoming an astronaut since childhood, but do you have what it takes?
The criteria
Becoming an astronaut is not simple, nor is it easy. Esa is looking for candidates with different profiles and backgrounds. However, there are some minimum requirements.

Researchers from the Oil and Gas Research Institute of the Russian Academy of Sciences and their Skoltech colleagues have surveyed the newest known 30-meter deep gas blowout crater on the Yamal Peninsula, which formed in the summer of 2020. The paper was published in the journal Geosciences.

Individually, California blackworms live an unremarkable life eating microorganisms in ponds and serving as tropical fish food for aquarium enthusiasts. But together, tens, hundreds, or thousands of the centimeter-long creatures can collaborate to form a "worm blob," a shape-shifting living liquid that collectively protects its members from drying out and helps them escape threats such as excess Robots sense human touch using camera and shadows

Soft robots may not be in touch with human feelings, but they are getting better at feeling human touch. Cornell University researchers have created a low-cost method for soft, deformable robots to detect a range of physical interactions, from pats to punches to hugs, without relying on touch at all. Instead, a USB camera located inside the robot captures the shadow movements of hand gestures on Placing cosmological constraints on quantum gravity phenomenology

A description of gravity compatible with the principles of quantum mechanics has long been a widely pursued goal in physics. Existing theories of this 'quantum gravity' often involve mathematical corrections to Heisenberg's Uncertainty Principle (HUP), which quantifies the inherent limits in the accuracy of any quantum measurement.
These corrections arise when gravitational interactions ar Emerging robotics technology may lead to better buildings in less time

Emerging robotics technology may soon help construction companies and contractors create buildings in less time at higher quality and at lower costs.
Purdue University innovators developed and are testing a novel construction robotic system that uses an innovative mechanical design with advances in computer vision sensing technology to work in a construction setting.
