A recent satellite hacking shows that end-of-life satellites may be vulnerable.

Israel punches above its weight in space science and exploration, as it does in most other arenas.
For example, the country developed its own line of orbital rockets, the Shavit (“Comet”) series, which has lofted a number of satellites over the years. And in April 2019, Israel’s Beresheet (“In the Beginning”) mission attempted to put a robotic lander down on the moon, something achieved only by the United States, the USSR/Russia and China — and nearly succeeded.
WASHINGTON – The U.S. Space Force in 2025 plans to launch to geostationary orbit three small satellites that will attempt to dock with a propellant tanker so they can be refueled in space.
The idea is to “test out pieces of the refueling infrastructure,” Col. Joseph Roth, director of innovation and prototyping at U.S. Space Systems Command, told SpaceNews last week at the Space Symposium in Colorado Springs.
The $50 million experiment, called Tetra-5, is run by the Space Force’s Space Enterprise Consortium. Bids for the project closed earlier this month.
WASHINGTON – As Maxar Technologies’ satellites continue to collect images of Russia’s invasion of Ukraine, the company is working with customers so it can allocate more capacity to meet U.S. government needs, said Maxar’s CEO Daniel Jablonsky.
With four satellites in orbit, “a lot of times we don’t have a lot of spare capacity,” Jablonsky said in an interview last week at the Space Symposium in Colorado Springs.
“But we made accommodations with some of our other customers to be able to surge capacity for the U.S. and allies,” he said. The company also gets about 200 requests a day for imagery from news media organizations.
The first 3D model of Earth’s magnetosphere could help us better understand how satellites cope with space weather.
Researchers used radiative cooling to generate enough to power LEDs or charge a cell phone.
NASA has agreed to test startup SpinLaunch’s kinetic launcher, a giant circular accelerator that aims to shoot 200 kilogram satellites into space.
The California-based SpinLaunch’s launcher is located at the Spaceport America facility in New Mexico where it will carry out a test flight with NASA later this year, according to the firm.
SpinLaunch says it will launch a NASA payload later this year after signing an agreement with the space agency.
SpaceX’s Starlink satellite internet service became the center of a global outage earlier today, with services having resumed soon after.
The night sky has been a source of information and wonder since the dawn of humankind — and it looks almost the same now as it did then.
But the night sky as we know it is on the precipice of changing dramatically due to the proliferation of satellites just a few hundred miles above Earth.
“For the first time in human history, we’re not going to have access to the night sky in the way that we’ve seen it,” Samantha Lawler, an assistant professor of astronomy at the University of Regina in Canada, said.
COLORADO SPRINGS — Megaconstellation startup E-Space is preparing to deploy the first of potentially hundreds of thousands of satellites on a Rocket Lab mission slated for no earlier than April 19.
Three E-space prototypes are part of the 34 payloads that Rocket Lab said April 5 are on the upcoming mission, including satellites for Alba Orbital, Astrix Astronautics, Aurora Propulsion Technologies, Unseenlabs and Swarm Technologies.
Rocket Lab will also attempt a mid-air helicopter capture of its Electron launch vehicle for the first time after the flight. The launch is set to commence within a 14-day window starting on April 19 and represents a major step in Rocket Lab’s plans to make the rocket reusable.
