    phys.org Astronomers discover two galaxies aligned in a way where their gravity acts as a compound lens

    An international team of astronomers has discovered an instance of two galaxies aligned in a way where their gravity acts as a compound lens. The group has written a paper describing the findings and posted it on the arXiv preprint server.

  • Thanks for sharing! Interesting to see that they went with cameras instead of conventional mirrors. More failure modes, but the auto-night-vision seems pretty neat.

    I recall that the original Tesla Semi concept had no mirrors, but they eventually added them for the production version. I wonder if we'll see more vehicles without mirrors in the future.

  • As ABL Space departs launch, the 1-ton rocket wars have a clear winner
  • Do you think we'll see a similar situation play out in the between the medium-lift launch vehicles (Neutron, MLV, Terran-R, Nova, etc.), or do you think that segment of the launch market is large enough to support multiple providers?

  • Launching Mass From the Moon Helped by Lunar Gravity Anomalies
  • He details how we can use quirks of lunar gravity to use a mass driver to send passive loads to lunar orbit, where they can then be picked up with active, high-efficiency systems and sent elsewhere in the solar system for processing.

    Anomalies in the Moon’s gravitational field have been known for some time. Typically, mission planners view them as a nuisance to be avoided, as they can cause satellite orbits to degrade more quickly than expected by nice, simple models. However, according to Dr. Janhunen, they could also be a help rather than a hindrance.

    This satellite mapped the Moon’s gravity in great detail and found several places on the lunar surface where a mass driver could potentially launch a passive payload into an orbit that would last up to nine days.

    Huh, so I'm understanding it correctly, it might be possible for the lumpy lunar gravitational field to circularize an orbit in lieu of an upper stage. Seems pretty nifty.

  • Why Are Tesla Cars Involved In More Fatalities Than Any Other Auto Brand?
  • when you’ve consumed all that hype around how quick a Tesla is, it’s easy to be influenced and want to smoke cars off the line at a red light, or just drive like a bat out of hell.

    owners just need to chillax a bit more. And Tesla vehicles are great for relaxing and driving calmly and smoothly — that’s how I normally drive these days

    It seems the article can be summarized in the two words, "skill issue".

    As ABL Space departs launch, the 1-ton rocket wars have a clear winner

    > A 7-year-old launch company that has yet to have a rocket successfully lift off announced a radical pivot on Thursday. Its new plan? Focusing on missile defense.

    > "We have made the decision to focus our efforts on national defense, and specifically on missile defense technologies," Piemont said. "We’ll have more to share soon on our roadmap and traction in this area. For now, suffice to say we see considerable opportunity to leverage RS1, GS0, the E2 engine, and the rest of the technology we’ve developed to date to enable a new type of research effort around missile defense technologies."

    > Over the last half decade or so, three US companies have credibly vied to develop rockets in the 1-ton class in terms of lift capacity. ABL has been competing alongside Relativity Space and Firefly to bring its rockets to market. ABL never took off. In March 2023, Relativity reached space with the Terran 1 rocket, but, due to second-stage issues, failed to reach orbit. Within weeks, Relativity announced it was shifting its focus to a medium-lift rocket, Terran R. Since then, the California-based launch company has moved along, but there are persistent rumors that it faces a cash crunch. > > Of the three, only Firefly has enjoyed success. The company's Alpha rocket has reached orbit on multiple occasions, and just this week Firefly announced that it completed a $175 million Series D fundraising round, resulting in a valuation of more than $2 billion. The 1-ton rocket wars are over: Firefly has won.

    spacenews.com Shotwell predicts Starship to be most valuable part of SpaceX

    While Starlink is becoming a moneymaker for SpaceX, the company’s president believes that Starship will have a bigger long-term impact.

    Shotwell predicts Starship to be most valuable part of SpaceX

    > “The company is incredibly valuable, I think, right now because of Starlink,” she said. “Starlink will add a zero, probably, at least as we continue to grow the Starlink system.” > > That growth comes in many different markets, from residential broadband services to maritime and aviation connectivity. SpaceX will begin offering direct-to-device services “within the next month or so,” she said, with an initial version for “very light data” and text messaging. > > However, she argued that Starship will be even more valuable to SpaceX in the long run. “Ultimately, I think Starship will be the thing that takes us over the top as one of the most valuable companies. We can’t even envision what Starship is going to do to humanity and humans’ lives, and I think that will be the most valuable part of SpaceX.”

    > One example she offered was using Starship to launch a satellite. If that satellite was not working, she explained, the satellite could be brought back into Starship’s payload bay to either be repaired or returned to Earth.

    > She predicted that Starship will rapidly eclipse the company’s existing Falcon family of rockets, which has launched more than 400 times. “I would not be surprised if we fly 400 Starship launches in the next four years,” she said. That will be in parallel with Falcon 9, but she suggested that vehicle could be retired, along with the Dragon spacecraft used for crew and cargo missions, in as little as six to eight years as customers move to Starship.
