Show HN: Tracecat – Open-source security alert automation / SOAR alternativeHi HN, we are building Tracecat (https://tracecat.com/), an open source automation platform for security alerts. Tracecat automates the tasks a security analyst has to do when responding to a security alert: e.g. contact victims, investigate security logs, report vulnerability.The average security analyst deals with 100 alerts per day. As soon as an alert comes in, you have to investigate and respond. An average alert takes ~30 minutes to analyze (and 100 x 30 min = 50 hours > one whole day) Lots of things get dropped, and this creates vulnerabilities. Many breaches can be traced back to week old alerts that didn’t get properly investigated.Since the risks and costs are so high, top security teams currently pay Splunk SOAR $100,000/year to help automate alert processing. It’s a click-and-drag workflow builder with webhooks, REST API integrations, and JSON processors. A security engineer would use it to build alert automations that look like this: (1) webhook to receive alert (e.g. unus
IMAGENew study finds that DART changed both orbit and shape of Dimorphos asteroidOn Sept. 26, 2022, NASA’s Double Asteroid Redirection Test (DART) spacecraft slammed into the side of the 170-meter-wide asteroid Dimorphos to test future asteroid deflection tactics in the event an asteroid was threatening Earth. Following impact, DART teams confirmed that the spacecraft’s collision with the asteroid had successfully deflected the asteroid by a small amount — proving the design of the deflector and allowing scientists and engineers to better understand the ways we can protect Earth from asteroids.
IMAGEAstronomers and megaconstellations learn to get alongIn the four years since skywatchers cried foul over Starlink satellites mucking up the night sky , the astronomy community has collaborated with SpaceX and other companies on ways to mitigate the impact of megaconstellations on optical and radio astronomy in the near term while seeking long-term regulatory solutions.
IMAGESpace One’s Kairos Explodes on Maiden FlightIt has been a tough start for the fledgling private aerospace industry in Japan. On March 13th 2024, private aerospace company SPACE ONE aimed to perform the first private satellite launch from Japan. Launching from the company’s Space Port Kii, the Kii-based Advanced & Instant ROcket System (KAIROS) rocket carried a payload for the Japanese government, a satellite that would’ve acted as a temporary contingency incase of malfunctions aboard active intelligence satellites. This satellite however would not be deployed, or even delivered to space, as about five seconds after the rocket launched, the rocket detonated.

IMAGEISS Roundup: Cygnus NG-20, Axiom Mission 3, and Progress MS-26This month, the International Space Station (ISS) has seen a flurry of activity, from experiments to vehicle arrivals and departures. Multiple resupply missions by Cygnus and Progress have kept the crew of Expedition 70 healthy onboard the Station. Meanwhile, a private mission from Axiom headed back to Earth with the first-ever all-European commercial crew, and SpaceX Crew-8 prepares to launch to the ISS in the coming days.

IMAGEIntuitive Machines’ Odysseus Achieves First Landing for CLPSOn Thursday, February 22nd, Intuitive Machines’ Nova-C lander Odysseus successfully touched down on the Moon, achieving the “ultimate milestone” for the IM-1 mission and marking the first major victory for NASA’s Commercial Lunar Payload Services (CLPS) initiative. After Powered Descent Initiation occurred at 5:11 PM CST, Odysseus’s main engine fired for approximately eleven minutes, bringing the vehicle down for a soft landing on the lunar highlands at 5:23 CST. Despite a slight pointing error which delayed acquisition of signal, the lander was confirmed to be on the surface and transmitting a few minutes after touchdown. At a press conference on February 23rd, Intuitive Machines CEO Stephen Altemus reported that the team currently believes the lander to be lying on its side, but otherwise intact. Odysseus is the first American spacecraft to have safely landed on the Moon since Apollo 17 in 1972, and the first to do so near the lunar South Pole.

IMAGEOp-Ed: Setting Up Camp, an Exploration of ArtemisAfter decades of dreaming, We Are Going! The rockets are flying, crews are in training, and the landers are under contract. Artemis will put the first woman and first person of color on the Moon by the end of this decade… But then what? A plan is slowly coming together. NASA along with its commercial and international partners intends to do so much more than flags and footprints. That next landing will be the start of a sustained campaign on the Lunar surface, one that will open up the Moon as a new frontier for international scientific collaboration and where we learn what we need to go to Mars.
IMAGELaunch HN: Danswer (YC W24) – Open-source AI search and chat over private dataHey HN! Chris and Yuhong here from Danswer (https://github.com/danswer-ai/danswer). We’re building an open source and self-hostable ChatGPT-style system that can access your team’s unique knowledge by connecting to 25 of the most common workplace tools (Slack, Google Drive, Jira, etc.). You ask questions in natural language and get back answers based on your team’s documents. Where relevant, answers are backed by citations and links to the exact documents used to generate them.Quick Demo: https://youtu.be/hqSouur2FXwOriginally Danswer was a side project motivated by a challenge we experienced at work. We noticed that as teams scale, finding the right information becomes more and more challenging. I recall being on call and helping a customer recover from a mission critical failure but the error was related to some obscure legacy feature I had never used. For most projects, a simple question to ChatGPT would have solved it; but in this moment, ChatGPT was completely clueless without add
