The Quiet Revolution in Space Tech

From $10,000 per kg, possibly down to $15 per kg to orbit.
What it means for the future of humanity.

The first galaxies in the universe are a mystery to us — but that could soon change.
The cosmos has come a long way (pun intended). But the most fantastic story of all time isn’t fully understood — especially the early chapters, ‘written’ in history during the first two to three hundred million years of the universe’s 13.8 billion-year existence.
The James Webb Space Telescope could be the key. The observatory can look about three times as far back in time than the iconic Hubble. The Webb will detect infrared wavelengths long enough to pierce through the dense smog of all the light and dust that sits between Earth and the furthest galactic posts, revealing information about the ancient universe where these wavelengths began their journey through space billions of years ago.

Scientists have confirmed the speed of sound on Mars, using equipment on the Perseverance rover to study the red planet’s atmosphere, which is very different to Earth’s.
What they discovered could have some strange consequences for communication between future Martians.
The findings suggest that trying to talk in Mars’ atmosphere might produce a weird effect, since higher-pitched sound seems to travel faster than bass notes. Not that we’d try, since Mars’ atmosphere is unbreathable, but it’s certainly fun to think about!
The next chance to see the northern lights may be coming soon after astronomers spotted a large object on the surface of the sun.
Nearly 50 years after it was collected, a lunar sample from the Apollo 17 mission has finally been opened at NASA’s Johnson Space Center in Houston. It’s one of the last unopened samples from the final Apollo mission to land humans on the moon.
“We have had an opportunity to open up this incredibly precious sample that’s been saved for 50 years under vacuum and we finally get to see what treasures are held within,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington, in a statement.
It was collected by NASA astronauts Eugene Cernan and Harrison “Jack” Schmitt in December 1972 when they hammered 14-inch (36-centimeter) cylindrical drive tubes into a landslide deposit in the Taurus-Littrow Valley. The two astronauts vacuum-sealed the tube while still on the lunar surface.
To develop the hypersonic vehicles of the future, we need to properly understand how to predict boundary layer transition on realistic vehicle shapes and what the minute effects of turbulent flow on hypersonic vehicles are. Data from the BOLT II flight experiment will help do just that.
Both the BOLT and BOLT II vehicles have a complex, swept geometry with a concave surface to represent a real hypersonic vehicle. The aim is to produce complex, real-world data that engineers and scientists can use to improve their models for predicting transition on hypersonic vehicles.
A separate experiment is run on each side of the vehicle, with one “smooth” side and one “rough” side. The flow running length along the vehicle is 1 meter, slightly larger than the original BOLT vehicle.

Statement from members of the earth and space science international community.
We are Earth and space scientists, science communicators, and educators dedicated to the discovery of and solutions to societal challenges. We issue this joint statement to call on world governments and global leaders to do everything possible to expedite the end to the brutal Russian assault on Ukraine. We welcome other professional scientific communities to join our appeal.
1. The Earth and Space Community is an ecosystem of researchers working together and supporting each other. At this moment, our colleagues in Ukraine are being shelled with missiles and many have been forced to escape with their families from the war zone. We salute “Science for Ukraine” grassroots efforts and urge world governments to support Ukrainian students and science professionals.
Regardless of Pandemics, Wars, Supply chain shocks…the Planets digital brain capacity continues its near exponential growth.
When added to the 728 hyperscale datacentres that were in operation at the end of 2021 and factoring in [the] many new datacentre plans that will be announced over the next two to three years, we forecast that by the end of 2026 there will be an installed base of nearly 1,200 hyperscale datacentres around the world.
“Almost 40% of the world’s operational hyperscale datacentres are located in the US, and the bulk of the developments in the pipeline will also be US-based, with China and Ireland name-checked as the second and third countries with the most new builds planned.” The future looks bright for hyperscale operators, with double-digit annual growth in total revenues supported in large part by cloud revenues that will be growing in the 20–30% per year range,”

“The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe,” observes physicist Michio Kaku. The neocortex, observed Carl Sagan is where “matter is transformed into consciousness.” Located deep in the brain’s center, the subcortex, the most evolutionarily ancient part of our brain, processes everything from our basic senses to long-term memories.
“Most Perfectly Organized Part”
Noble Prize laureate Roger Penrose suggest that the human brain and its cerebral cortex, the folded gray matter that covers the first couple of millimeters of the outer brain like wrapping paper, is more complex than our Milky Way Galaxy. “If you look at the entire physical cosmos,” Penrose says, our brains are a tiny, tiny part of it. But they’re the most perfectly organized part.”
