Unlike a traditional rocket engine, which consists of individually designed parts that are combined together the AI designed rocket engine was 3D printed as one continuous piece. This includes both the combustion chamber where fuel and oxidiser is burned and the surface channels, through which the fuel is circulated to cool the chamber and keep it from overheating.
“In a rocket, the cooling channels are generally welded onto the combustion chamber, which through wear and tear can cause errors and explosions,” explained Hyperganic’s design director Duy-Anh Pham.
For the past number of years I’ve been taking about the rise of so called Creative Machines, Artificial Intelligence (AI) based “innovation” machines, that can design and innovate things for themselves without any human intervention – things such as aircraft parts, chairs, fashion lines, interplanetary rovers, self-evolving robots, and Under Armour trainers. And now those same creative machines have made yet another leap, and again it’s another first for the space industry, after German software company Hyperganic announced they’d developed a 3D printed rocket engine prototype, which was completely designed by AI.
Called “Spinnaker3,” this drag sail isn’t the first to be launched into space. But it is among the first to be large enough for deorbiting the upper stage of a launch vehicle. The Firefly Alpha launch will target an orbit altitude of about 200 miles, but the Spinnaker3 drag sail is capable of providing deorbit capability from orbit altitudes of 400 miles or greater.
WEST LAFAYETTE, Ind. — A rocket is going up into space with a drag sail. The goal? For the drag sail to bring the rocket back to Earth, preventing it from becoming like the thousands of pieces of space junk in Earth’s lower orbit.
The drag sail, developed by Purdue University engineers, will be on board a Firefly Aerospace rocket expected to launch in November from Vandenberg Air Force Base in California.
SpaceX has fired up the latest prototype of its Starship Mars-colonizing spacecraft, keeping the vehicle on track for a possible test flight this weekend.
Mike Snead, P.E., president of the Spacefaring Institute, was invited to present at the Envision Humanity conference held in Portugal on 18 July 2020. This presentation was delivered via video. It addresses the world green energy needed to “globally reset” human civilization using astroelectricity (GEO space-based solar power) to achieve sustainable, prosperous living worldwide. The presentation also shows why the “Green New Deal’s” call to use terrestrial nuclear and renewable energy to replace fossil carbon fuels is not a practical solution. The presentation provides an interesting way to understand the magnitude of the engineering challenge and options available to complete this important transition to sustainable energy.
The first two episodes will be directed by Ridley Scott, who has a history of producing grandiose, high-concept, philosophical sci-fi (see: Prometheus and Alien Covenant) as well as treatises on religious tribalism (like in Kingdom of Heaven).
The visual spectacle aims to be a think piece on the role of faith in civilization.
Taiwanese medtech firm Brain Navi has created a robot that autonomously swabs your nose as part of a test for COVID-19. The startup says the robot could make mass-testing faster and more reliable, but doctors say the machine might just be too scary for patients to bear.
This piece was written as part of the Artificial Intelligence and International Stability Project at the Center for a New American Security, an independent, nonprofit organization based in Washington, D.C. Funded by Carnegie Corporation of New York, the project promotes thinking and analysis on AI and international stability. Given the likely importance that advances in artificial intelligence could play in shaping our future, it is critical to begin a discussion about ways to take advantage of the benefits of AI and autonomous systems, while mitigating the risks. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE.
AI deception: when your artificial intelligence learns to lie.

Millions of us use Bluetooth wireless communications every day—to make phone calls when driving, with our fitness trackers, streaming at work or play. Innocent enough, seemingly. But no technology comes without a warning: a recently discovered Bluetooth vulnerability allows hackers to spy on your conversations or take control of your smart phone. The vulnerability deals with the encryption between two devices. It even has a name—a KNOB hack (Key Negotiation Of Bluetooth).
This is not the first time Bluetooth has been hacked and it likely won’t be the last. And this one has its limitations. To take advantage of the KNOB vulnerability the hacker has to be in close proximity of your phone. There is also currently no evidence that this vulnerability has been exploited maliciously.
Still, for the sake of cyber hygiene, take the following steps to protect yourself from a KNOB hack: • Install updates for your smart phone as they become available. • Remove devices paired with your phone that you no longer need or recognize. • Turn off Bluetooth when you are not using it.
