Lockheed Martin offers to acquire Terran Orbital

Posted by in categories: business, space

Under the proposal, Lockheed would pay $1 per share of Terran Orbital stock it does not currently own, valuing the company at a little under $200 million. Lockheed would pay more than $70 million to buy outstanding stock warrants and assume or repay $313 million in Terran Orbital debt.

“Terran represents an attractive opportunity for Lockheed Martin, and we are treating the potential Transaction as a strategic priority,” Lockheed stated in the letter. “Terran’s superior capabilities and business momentum align with one of Lockheed Martin Space’s strategic growth priorities and the Transaction would accelerate that strategy.”

ISS Roundup: Cygnus NG-20, Axiom Mission 3, and Progress MS-26

Posted by in category: space

This 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.

Northrop Grumman’s 20th Cygnus mission (NG-20) was berthed to the Station’s Unity module on Feb. 1, beginning the month off with a strong start. NG-20 was launched on a SpaceX Falcon 9 on Jan. 30 at 12:07 PM EST (17:07 UTC) from Space Launch Complex 40 at the Cape Canaveral Space Force Station.

Experiments on the ISS are actively gaining new insight into possibilities that were never attainable on Earth. Cargo resupply vehicles like Cygnus help carry new experiments and supplies to the Station, supporting these advancements.

Mars had its own version of plate tectonics

Posted by in category: space

Plate tectonics is not something most people would associate with Mars. In fact, the planet’s dead core is one of the primary reasons for its famous lack of a magnetic field. And since active planetary cores are one of the primary driving factors of plate tectonics, it seems obvious why that general conception holds.

However, Mars has some features that we think of as corresponding with plate tectonics—volcanoes. A new paper from researchers at the University of Hong Kong (HKU) looks at how different types of plate tectonics could have formed different types of volcanoes on the surface of Mars.

What shape is the universe?

Posted by in categories: evolution, space

Key Takeaways:

Princeton University cosmologist David Spergel emphasizes that the universe’s shape reveals crucial insights into its historical evolution and future trajectory. Questions regarding whether the universe will expand indefinitely or eventually contract, as well as its finiteness or infiniteness, all pivot on its shape.

There’s one last place Planet Nine could be Hiding

Posted by in category: space

A study recently submitted to The Astronomical Journal continues to search for the elusive Planet Nine (also called Planet X), which is a hypothetical planet that potentially orbits in the outer reaches of the solar system and well beyond the orbit of the dwarf planet, Pluto.

The goal of this study, which is available on the pre-print server arXiv, was to narrow down the possible locations of Planet Nine and holds the potential to help researchers better understand the makeup of our solar system, along with its formation and evolutionary processes. So, what was the motivation behind this study regarding narrowing down the location of a potential Planet 9?

Dr. Mike Brown, who is a Richard and Barbara Rosenberg Professor of Astronomy at Caltech and lead author of the study, tells Universe Today, “We are continuing to try to systematically cover all of the regions of the sky where we predict Planet Nine to be. Using data from Pan-STARRS allowed us to cover the largest region to date.”

Seeking Solutions to Underwater Noise Pollution

Posted by in categories: engineering, finance, space

From early in his career, Kamal Kesour understood the damaging effects of urban noise and was aware of the instrumentation used to measure and control it. He had lived in big cities, and after his PhD he went to work for an environmental consulting firm that specialized in urban noise. But it wasn’t until later, during a research position at Innovation Maritime in Canada, that he realized marine mammals can experience similarly noisy environments. This noise comes from underwater vibrations generated by shipping vessels transporting goods around the world. Kesour now has a career helping to make maritime transportation vessels less noisy.

Kesour has spent the past few years in Rimouski, Canada, at the Marine Acoustic Research Station (MARS), which lies on the banks of the St. Lawrence Estuary and is jointly led by Innovation Maritime, the Rimouski Institute of Marine Sciences, and engineering consultancy OpDAQ systems. There, he measures ambient underwater noise from ships as they pass on their way to and from the Atlantic Ocean or North America’s Great Lakes. He also conducts on-ship measurements to help pinpoint noise sources and to “fingerprint” the vibrations of individual ships. Physics Magazine caught up with Kesour to learn more about his measurements and their implications for noise pollution produced by the shipping industry.
