WASHINGTON — The Australian Department of Defence announced the cancellation of its JP9102 military satellite program, an estimated $5 billion project awarded to Lockheed Martin just 18 months ago, citing shifts in satellite technology and the market’s pivot toward multi-orbit space communications.

The cancellation of Australia’s JP9102 satellite program is yet another sign of the disruptive impact that low Earth orbit space internet services, led by the rapid growth of SpaceX’s Starlink, are having on the traditional satellite communications industry and government procurement models.

JP9102, or Defence Joint Project 9,102, was launched in 2021 with plans to develop between three to five geostationary satellites and ground systems, marking one of Australia’s most ambitious space infrastructure ventures.

Data from space shows water tilting up toward the north side of the Dickson Fjord as it sloshed from south to north and back every 90 seconds for nine days after a 2023 rockslide.

The international Surface Water and Ocean Topography (SWOT) satellite mission, a collaboration between NASA and France’s CNES (Centre National d’Études Spatiales), detected the unique contours of a tsunami that sloshed within the steep walls of a fjord in Greenland in September 2023. Triggered by a massive rockslide, the tsunami generated a seismic rumble that reverberated around the world for nine days. An international research team that included seismologists, geophysicists, and oceanographers recently reported on the event after a year of analyzing data.

The SWOT satellite collected water elevation measurements in Dickson Fjord on Sept. 17, 2023, the day after the initial rockslide and tsunami. The data was compared with measurements made under normal conditions a few weeks prior, on Aug. 6, 2023.

WASHINGTON — Lockheed Martin Corp announced Oct. 30 it has completed the acquisition of small satellite manufacturer Terran Orbital. The approximately $450 million acquisition deal deepens Lockheed Martin’s foothold in the commercial satellite sector and culminates a partnership that began in 2017.

The acquisition positions Lockheed to leverage Terran’s expertise in low-cost satellite production for both military and commercial ventures. Lockheed Martin stressed that Terran Orbital, now rebranded as “Terran Orbital, a Lockheed Martin Company,” will continue to operate as a merchant supplier for the broader space industry.

The completed acquisition caps Lockheed Martin’s years-long relationship with Terran Orbital, formerly Tyvak Nano-Satellite Systems. The smallsat specialist, founded in 2011, initially focused on nanosatellites and cubesats, but transitioned to building larger satellite platforms after it rebranded in 2022. That shift in focus followed Terran Orbital’s public listing through a special purpose acquisition company (SPAC) merger, which aimed to accelerate its commercial growth.

Twenty Starlink satellites were launched into space early Wednesday morning when a SpaceX rocket launched from the Santa Barbara County coast.

The rocket soared over the Southern California coast after the 5:07 a.m. launch from Vandenberg Space Force Base northwest of Santa Barbara.

Halloween is on Thursday, Oct. 31 — but parts of the Treasure Coast may get a nice treat the night before.

SpaceX is targeting Wednesday, Oct. 30, to launch another payload of Starlink broadband satellites into low-Earth orbit from Cape Canaveral Space Force Station. Depending on weather and visibility, parts of Indian River County might see a nice streak in the sky.

Below are suggestions on where to watch the rocket launch from this area and other things to know. If there are changes to the launch schedule, this story will be updated.

Dr. Lauren Schurmeier: “The methane clathrate crust warms Titan’s interior and causes surprisingly rapid topographic relaxation, which results in crater shallowing at a rate that is close to that of fast-moving warm glaciers on Earth.”

How does Saturn’s largest moon, Titan, have such a methane-rich atmosphere? This is what a recent study published in The Planetary Science Journal hopes to address as a team of researchers investigated how methane that resides with Titan’s crust could be responsible for the lack of depth in Titan’s impact craters, which could explain why Titan’s atmosphere has so much methane, as well. This study holds the potential to help researchers better understand the formation and evolution of Titan and whether it could host life as we know it.

For the study, the researchers used computer models to simulate the formation and evolution of impact craters on Titan, of which only approximately 90 have been identified via satellite imagery from NASA’s Cassini spacecraft.

“This was very surprising because, based on other moons, we expect to see many more impact craters on the surface and craters that are much deeper than what we observe on Titan,” said Dr. Lauren Schurmeier, who is a research associate in the Hawai‘i Institute of Geophysics and Planetology (HIGP) and lead author of the study. “We realized something unique to Titan must be making them become shallower and disappear relatively quickly.”

It’s like Uber Eats for the Sun.

The company is called Reflect Orbital.

These two guys figured out if they launch reflective satellites and position them in just the right constellation, at just the right angle, they can beam sunlight to any spot on Earth.
