#China aims to launch nearly 13,000 #satellites to ‘suppress’ Elon #Musk’s #Starlink, researchers say

The Chinese satellites could also be placed in “orbits where the Starlink constellation has not yet reached”, the researchers said, adding that they would “gain opportunities and advantages at other orbital altitudes, and even suppress Starlink”.

The Chinese satellites could be equipped with an anti-Starlink payload to carry out various missions, such as conducting “close-range, long-term #surveillance of Starlink satellites”, they said.

China to launch nearly 13,000 satellites to ‘suppress’ Starlink: researchers

The satellite constellation is likely to be launched quickly to prevent SpaceX from hogging ‘low-orbit resources’, according to PLA space scientists.

GROUND-BASED IMAGES OF #ASTEROID #STRIKE: Yesterday, NASA's DART spacecraft hit asteroid Dimorphos--an incredible, dramatic bullseye 11 million kilometers from Earth. Surprising even NASA, ground-based telescopes had no trouble seeing the impact. Astronomers with the Asteroid Terrestrial-impact Last Alert System (ATLAS) in Hawaii recorded a bright cloud of debris:

This was the result of the 1,340-pound spacecraft plunging into Dimorphos at 14,000 mph. Most of the debris is probably asteroid dust, but some of DART may be in there, too. A similar video was recorded by the 1-meter Lesedi telescope in South Africa.

Mission scientsts say DART hit the asteroid less than 17 meters off center. Think about that: 17 meters off at a distance of 11 million kilometers. NASA still has the right stuff.

Now that the dust has cleared, astronomers are monitoring #Dimorphos's #orbit to find out whether or not it has changed in response to the strike. Even a slight shift would prove that human tech can alter an asteroid's trajectory--a possible strategy for future Planetary Defense.

I had one of those "Why didn't that ever occur to me before?" moments. The time between the #Equinoxes is not symmetrical. It's about 186 days between the #March and #September equinoxes and about 179 days from September to March. This is because the speed of the #Earth in its #orbit varies as it's #elliptical rather than circular. I never bothered to count the days and yet it's "obvious" when you look at the calendar. This gives an eccentricity of the orbit to be around 0.015 which is remarkably close to the actual value.
