China is building a specially designed ship for launching rockets into space from the seas in an effort to boost its capacity to launch satellites and recover rocket stages.

The 533 feet (162.5 meters) long, 131 feet (40 meters) wide “New-type rocket launching vessel” is being constructed for use with the new China Oriental Spaceport at Haiyang, Shandong province on the Eastern coast.

In a nutshell: In the 21st century, there’s a new space race, primarily between Tesla (SpaceX) and Amazon (Blue Origin). Both are concentrating on traditional methods of launching satellites into space—namely, big rockets. However, a small space startup called SpinLaunch is developing a cheaper and environmentally cleaner way of launching satellites.

SpinLaunch is using a gigantic centrifuge to shoot stuff into space. By “stuff,” we mean things that can withstand the G-force created by being spun at 5,000 miles per hour (over 10,000 Gs), which is a category of stuff that does not yet include satellites. However, it did launch a missile-like projectile tens of thousands of feet into the air last month, using only 20 percent of the accelerator’s power.

A new study examines Kamo‘oalewa, one of Earth’s quasi-satellites that may have been ejected from the Moon in a collision that flung it out of our system.

It is interesting to see Starlink evolve and move towards massive expansion. Currently, Starlink has only launched 64 laser satellites but this number should grow dramatically in the coming months. (All future Starlink satellites will include lasers.)

Their new Starlink dish will be a lot cheaper to produce which is important as originally the first Starlink dish cost $3,000 to make and SpaceX was selling it for $500. It has already gone through multiple generations and this rectangular dish should cost around $650 to make. (With the original dish, if they had sold a million of them, they would have lost 2.5 billion dollars which would have been painful.)

SpaceX has unveiled a new Starlink satellite dish, sporting a new rectangular design for customers in the United States. The company’s website is showing the new design for visitors showing U.S. IP addresses.

O,.o.

A near-Earth asteroid known as Kamo‘oalewa might be made of a stray chunk of the Moon, scientists have said.

Kamo‘oalewa is one of a mysterious and little-understood set of objects called quasi-satellites. It is an asteroid that orbits around the Sun but remains close to the Earth.

Sandia National Laboratories is developing an avocado-sized vacuum chamber made out of titanium and sapphire that could one day use quantum mechanical sensors to provide GPS-grade navigation without the need for satellites.

In only a few short decades, GPS has gone from a military technology to finding so many everyday applications that modern society is now dependent on it. However, GPS is not always available in places like high polar latitudes or in deep mountain valleys, and it can be jammed or spoofed.

The vulnerability of GPS and similar systems lies in their dependence on constellations of satellites that orbit the Earth. These satellites emit time-stamped signals that are synced to atomic clocks. Using these signals, a GPS receiver in something as small as a wristwatch can use the Doppler effect on the satellite signals as they pass overhead to make an extremely precise fix on the receiver’s position and velocity. If these signals are interrupted or corrupted, the system fails.

*To date, most studies have focused on understanding how much carbon is stored above ground (in trees and other plants, for example). This research, however, revealed that when you look below ground and get into deeper levels of soil, there are massive deposits of carbon.*

Canada’s first-ever national carbon map reveals the location of billions — yes, billions — of tonnes of carbon stored in ecosystems across the country. This data, and how we use it, could alter the pace of climate change.

Why use unsustainable rocket propellants for small satellite launches when you could just catapult them into space?

China’s military has built a fake US Navy aircraft carrier and other warships for possible missile target practice, according to new satellite images published Sunday.

The images, captured by Colorado-based satellite imagery company Maxar Technologies, show a full-scale outline of a carrier and at least two Arleigh Burke-class destroyers at what appears to be a new target range complex in the Taklamakan Desert, part of China’s notorious Xinjiang province.

One of the mockups included the funnels and weapons systems featured on the destroyers, according to an analysis by the US Naval Institute.
