WASHINGTON — Artificial intelligence startup Wallaroo Labs won a $1.5 million contract from the U.S. Space Force to continue the development of machine learning models for edge computers in orbit. The New York-based company, known as Wallaroo.ai, is partnered with New Mexico State University for the Small Business Technology Transfer Phase 2 contract, announced Aug.

WASHINGTON — SkyWatch, a satellite data distributor based in Ontario, Canada, announced a new imagery product that combines radar and optical images.   SkyWatch operates a platform called EarthCache that gives its customers access to commercial satellite data. The company said there is now a growing demand for integrated images that combine visually appealing pictures from

WASHINGTON — Momentus recently cut its workforce by 30% as the cash-strapped company seeks to reduce its costs while looking for “strategic options” to raise funding. In an Aug. 14 earnings call about its second quarter financial results, Eric Williams, chief financial officer of Momentus, said that the company reduced its headcount, including both full-time

TAMPA, Fla. — Terran Orbital expects to get $180 million this year from Rivada Space as it prepares to build 300 satellites for the venture, even as plans to fund the full $2.4 billion manufacturing contract remain under wraps. It would be the first significant revenues Terran Orbital has gained from Rivada under a contract

WASHINGTON — BAE Systems, a defense and security conglomerate based in the United Kingdom, announced Aug. 17 it intends to acquire Ball Aerospace for $5.5 billion. Ball Aerospace, based in Westminster, Colorado, is a manufacturer of spacecraft, components and other systems for military, civil and commercial space applications.  The acquisition would give BAE Systems “strong

WASHINGTON — The U.S. Space Force intends to award Northrop Grumman a sole-source contract to develop two ground-based radar sites to track space objects.  These would be the second and third sites of the Space Force’s planned network of sensors known as the Deep Space Advanced Radar Capability (DARC). Northrop Grumman in February 2022 won

Maths not mystics Kit Yates’ new book offers a gold mine of anecdotes about how maths can help us to make choices about the future, including how psychics use ruses to appear to have the same power.

When the materials scientist Ross Colman and colleagues read a preprint claiming that a material called LK-99 is a superconductor at room temperature and ambient pressure, they set out to replicate the result in their lab. But unlike other scientists doing the same thing, Colman’s group decided to share their work with the public in

Wide open question: binary-star observations back MOND.(Courtesy: NASA Goddard Space Flight Center/Chris Smith (USRA)) A new study of data from the European Space Agency’s Gaia space mission claims to have found evidence of gravity acting contrary to the predictions of Newton and Einstein, but not everyone agrees that this is the smoking gun for a

TAMPA, Fla. — Viasat is in the early stages of exploring how to use L-band spectrum from newly acquired Inmarsat to connect consumer devices directly from space, including potentially from small satellites in low Earth orbit (LEO). “We are still exploring what our roadmap and execution plan should be,” Viasat president Guru Gowrappan said in

For millennia, humans have used units of measurement based on aspects of the human body. Familiar examples include the fathom (arm span) and the qubit (forearm length). Our guest in this episode of the Physics World Weekly podcast is the Finnish social scientist Roope Kaaronen, who has studied the development and use of body-based units

WASHINGTON — The startup Scout Space in partnership with the Stanford University Space Rendezvous Laboratory won a $1.5 million contract to help the U.S. Space to characterize spacecraft and debris objects, the company said Aug. 10. Scout, founded in 2019, is developing technologies for on-orbit navigation and tracking. It won a Phase 2 Small Business

TAMPA, Fla. — Small satellite operator Lynk Global has started initial direct-to-device services in a small part of the Cook Islands in its second commercial launch with a local telco. Phones on mobile operator Vodafone Cook Islands’ network can now periodically send and receive text messages via Lynk’s satellites around Manuae, an uninhabited island in

Good vibrations: the new sensing system uses interactions between photons and phonons to determine several properties of an optical fibre. (Courtesy: iStock/Gregory DUBUS) Researchers in China have shown how measurements of strain, temperature and vibration can be made simultaneously on a single optical fibre. This could be used to create a fibre-based system to monitor

LOGAN, Utah – The National Reconnaissance Office is eager to work with partners who are developing advanced technology for satellites and ground systems. “We’re eager to collaborate with industry and academia in advancing these capabilities and expanding our future architecture,” U.S. Space Force Col.
