We humans have a wonderful ability to keep developing, innovating, and engineering bigger, better, and faster contraptions. Close to Earth, we’ve been soaring through the skies in airplanes since 1903 thanks to the Wright brothers, and we’ve been launching spacecraft into space since 1957 when the Soviet Union rocketed the Sputnik satellite above our heads.

The team discovered a way of stabilizing detonation for hypersonic propulsion by creating a hypersonic reaction chamber for jet propulsions.

So low that Starlink satellites have started photobombing its images.

Starlink and other broadband satellite constellations will threaten astronomical viewing in the upcoming years. Today, a team of astronomers has demonstrated that the satellite issue can’t be solved even by the Hubble Space Telescope.

In December 2019, the United States established its new space force: the United States Space Force. A logical step in a globalized and digitized world whose infrastructure depends on satellites in space. This infrastructure is under threat. Also by a resurgence of conflict between East and West. This episode of Spacetime describes how the military conquered space and why the world is in a new arms race in Earth orbit.

A NASA-led research team used satellite imagery and artificial intelligence methods to map billions of discrete tree crowns down to a 50-cm scale. The images encompassed a large swath of arid northern Africa, from the Atlantic to the Red Sea. Allometric equations based on previous tree sampling allowed the researchers to convert imagery into estimates of tree wood, foliage, root size, and carbon sequestration.

The new NASA estimation, published in the journal Nature, was surprisingly low. While the typical estimation of a region’s carbon stock might rely on counting small areas and extrapolating results upwards, the NASA demonstrated technique only counts the trees that are actually there, down to the individual tree. Jules Bayala and Meine van Noordwijk published a News & Views article in the same journal commenting on the NASA team’s work.

ALGORITHMS TURN PHOTO SHAPSHOTS INTO 3D VIDEO AND OR IMMERSIVE SPACE. This has been termed “Neural Radiance Fields.” Now Google Maps wants to turn Google Maps into a gigantic 3D space. Three videos below demonstrate the method. 1) A simple demonstration, 2) Google’s immersive maps, and 3) Using this principle to make dark, grainy photographs clear and immersive.

This technique is different from “time of flight” cameras which make a 3D snapshot based on the time light takes to travel to and from objects, but combined with this technology, and with a constellation of microsatellites as large as cell phones, a new version of “Google Earth” with live, continual imaging of the whole planet could eventually be envisioned.

NASA’s Transiting Exoplanet Survey Satellite is an all-sky survey mission that will discover thousands of exoplanets around nearby bright stars. TESS launched April 18, 2018 aboard a SpaceX Falcon 9 rocket.

- and Yes TESS found a second exoplanet like Earth over 60 million light years away. A link about it is in this one.

The new Starlink satellites are a precursor for larger models that will eventually launch aboard Starship.

SpaceX lifted the first batch of its new Starlink “V2 mini” satellites to orbit on Monday, February 27. The private space firm launched 21 of the new generation satellites aboard a Falcon 9 rocket that also came down to perform the 100th successful booster landing in a row for the company.

The Starlink mission took to the skies at 6:13 pm EST (2313 GMT) from Florida’s Cape Canaveral Space Force Station. The launch was delayed roughly five hours before liftoff due to “a space weather concern,” SpaceX explained on Twitter.

However, these ones are different to the several thousand Starlink satellites that are already circling Earth.

That’s because they sport a more modern and powerful design that gives them four times the capacity for serving customers compared to the original design, SpaceX said. So, yes, it means faster internet speeds for customers.

SpaceX chief Elon Musk confirmed the successful deployment of the new satellites in a tweet.
