SpaceX sent one of its first-stage boosters skyward for the 11th time on Tuesday evening. However, unlike its 10 previous flights, this time it didn’t return.
The mission launched from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida at 9:57 p.m. ET, lighting up the night sky as the Falcon 9 rocket roared toward space.
Thirty-five minutes after leaving the launchpad, the Falcon 9’s second stage deployed a communications satellite to a geosynchronous transfer orbit for French satellite operator Eutelsat.
A SpaceX recovery ship is headed more than a thousand kilometers downrange to support the second expendable Falcon 9 rocket launch in nine days.
No earlier than (NET) 9:57 pm EST (02:57 UTC) on Monday, November 21st, a Falcon 9 rocket is scheduled to lift off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad carrying the Eutelsat 10B geostationary communications satellite. For unknown reasons, the French communications provider paid extra to get as much performance as possible out of Falcon 9, requiring SpaceX to expend the rocket’s booster instead of attempting to land and reuse it.
The mission will be Eutelsat’s third Falcon 9 launch in less than three weeks and will wrap up a trio of launch contracts the company secretly signed with SpaceX to move satellites off of competitor Ariane Group’s unavailable Ariane 5 and delayed Ariane 6 rockets. In a rare coincidence, Eutelsat 10B will also be SpaceX’s second expendable Falcon 9 launch in a row and the third Falcon launch to expend a booster this month. But like those two other missions, not all of the Falcon rocket tasked with launching Eutelsat 10B will be lost.
A new nanoscale 3D printing material developed by Stanford University engineers may provide superior structural protection for satellites, drones, and microelectronics.
A dual-phase, nanostructured high-entropy alloy that has been 3D printed by researchers from the University of Massachusetts Amherst and the Georgia Institute of Technology is stronger and more ductile than other cutting-edge additively manufactured materials. This discovery could lead to higher-performance components for use in aerospace, medicine, energy, and transportation.
High entropy alloys (HEAs), as they are called, have gained popularity as a new paradigm in materials science over the past 15 years. They allow for the creation of a nearly limitless number of different alloy designs since they include five or more elements in nearly equal amounts. Brass, carbon steel, stainless steel, and bronze are examples of traditional alloys that mix a principal element with one or more trace elements.
A new nanoscale 3D printing material developed by Stanford University engineers may provide superior structural protection for satellites, drones, and microelectronicsAn improved lightweight, a protective lattice that can absorb twice as much energy as previous materials of a similar density has been developed by engineers for nanoscale 3D printing.
According to the study led by Stanford University, a nanoscale 3D printing material, which creates structures that are a fraction of the width of a human hair, will enable to print of materials that are available for use, especially when printing at very small scales.

The 693-square-foot array is designed to provide 5G broadband connectivity directly with cellular devices via 3GPP standard frequencies.
Bluewalker 3 satellite, a test satellite by Texas-based firm AST SpaceMobile deployed its largest commercial communications array ever flow in space, in low Earth orbit, the company announced on Monday. The satellite was launched on a SpaceX Falcon 9 rocket in September, Interesting Engineering.

The 693-square-foot (64 square meters) array is designed to directly provide 5G broadband connectivity with cellular devices via 3GPP standard frequencies. According to the release, the satellite could have a field of view of over 30,000 square miles on the surface of the Earth.
A toaster oven-sized NASA spacecraft will pave the way for a lunar orbital station that will help the U.S. space agency establish a permanent presence on the moon.
CAPSTONE, the first cubesat mission to ever visit the moon, was launched from New Zealand by a Rocket Lab Electron rocket on June 28 and it was designed to test the stability of the orbit NASA intends to use for its lunar Gateway orbital outpost.

NASA announced in a blog update that its 55-pound (25-kilogram) CAPSTONE cubesat spacecraft successfully inserted itself into orbit around the moon on Sunday, November 13.

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.”
Gamma-ray bursts (GRBs) have been detected by satellites orbiting Earth as luminous flashes of the most energetic gamma-ray radiation lasting milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies, billions of light years from Earth.
A sub-type of GRB known as a short-duration GRB starts life when two neutron stars collide. These ultra-dense stars have the mass of our sun compressed down to half the size of a city like London, and in the final moments of their life, just before triggering a GRB, they generate ripples in space-time—known to astronomers as gravitational waves.
Until now, space scientists have largely agreed that the “engine” powering such energetic and short-lived bursts must always come from a newly formed black hole (a region of space-time where gravity is so strong that nothing, not even light, can escape from it). However, new research by an international team of astrophysicists, led by Dr. Nuria Jordana-Mitjans at the University of Bath, is challenging this scientific orthodoxy.
Arthur C. Clarke, science fiction author and futurist, crossed paths with the scientists of the Bell System on numerous occasions. In 1945, he concurrently, but independently, conceived of the first concept for a communications satellite at the same time as Bell Labs scientist, John Robinson Pierce too, was a science fiction writer. To avoid any conflict with his day job at Bell Labs, Pierce published his stories under the pseudonym J.J. Coupling.
In the early 1960s, Clarke visited Pierce at Bell Labs. During his visit, Clarke saw and heard the voice synthesis experiments going on at the labs by John L. Kelly and Max Mathews, including Mathews’ computer vocal version of “Bicycle Built for Two”. Clarke later incorporated this singing computer into the climactic scene in the screenplay for the movie 2001: A Space Odyssey, where the computer HAL9000 sings the same song. According to Bob Lucky, another Bell Labs scientist, on the same visit, Clarke also saw an early Picturephone, and incorporated that into 2001 as well.
In 1976, AT&T and MIT held a conference on futurism and technology, attended by scientists, theorists, academics and futurists. This interview with Clarke during this conference is remarkably prescient—especially about the evolution of communications systems for the next 30+ years.
The interview was conducted for an episode of a Bell System newsmagazine, but this is the raw interview footage.
