WASHINGTON — Lockheed Martin is experiencing a growth spurt in an unexpected corner of its business: small satellites. While traditionally known for its expertise in GPS and giant geostationary (GEO) satellites, the company has quietly built a backlog of 100 smallsats on order from Department of Defense and intelligence customers.

“This is probably a different picture than many of you may have in our minds” about what the company does, Johnathon Caldwell, head of Lockheed Martin’s military space business, told a military conference Feb. 14.

Speaking at the Air & Space Forces Association’s Warfare Conference in Aurora, Colorado, Caldwell said a greater focus on small satellites began with the company’s pursuit of Space Development Agency contracts. SDA is building a proliferated mesh network of satellites in low Earth orbit for the Defense Department, and unlike traditional cost-plus defense programs, the agency demands fixed-price bids from satellite manufacturers.

WASHINGTON — Viasat announced it completed the first satellite broadband upgrade on board a Military Sealift Command ship, and expects to update 105 vessels over the next year. The work is part of a $578 million contract that Inmarsat won in 2022 before it was acquired by rival satellite operator Viasat.

The U.S. Navy’s sealift organization, responsible for providing ocean transportation to the Department of Defense, operates a fleet of approximately 125 civilian-crewed ships that replenish Navy vessels at sea, transporting military equipment and personnel, and strategically positioning cargo around the world.

Viasat is revamping the ships’ satellite network from Ku-band to the company’s Global Xpress Ka-band and the ELERA L-band systems.

Russia is planning on launching a nuclear weapon into orbit, where it will threaten US national security by either being used to strike the US within a matter of moments or be used to knock out US satellite grids in a single explosion. The US is convening national security meetings to find a way to stop this launch from happening.

SpaceX CEO Elon Musk sets ambitious goals for Starship, including a Moon mission in 5 years, a private space station, and Pentagon interest.

Launching rockets into space with atomic bombs is a crazy idea that was thankfully discarded many decades ago. But as Richard Corfield discovers, the potential of using the energy from nuclear-powered engines to drive space travel is back on NASA’s agenda.

In 1914 H G Wells published The World Set Free, a novel based on the notion that radium might one day power spaceships. Wells, who was familiar with the work of physicists such as Ernest Rutherford, knew that radium could produce heat and envisaged it being used to turn a turbine. The book might have been a work of fiction, but The World Set Free correctly foresaw the potential of what one might call “atomic spaceships”

The idea of using nuclear energy for space travel took hold in the 1950s when the public – having witnessed the horrors of Hiroshima and Nagasaki – gradually became convinced of the utility of nuclear power for peaceful purposes. Thanks to programmes such as America’s Atoms for Peace, people began to see that nuclear power could be used for energy and transport. But perhaps the most radical application lay in spaceflight.

A team of molecular engineers have developed a type of plastic that can be shape-shifted using tempering. In their paper published in the journal Science the team, from the University of Chicago, with a colleagues from the US DEVCOM Army Research Laboratory, Aberdeen Proving Ground, the National Institutes of Standards and Technology and the NASA Glenn Research Center, describe how they made their plastic and how well it was able to shape shift when they applied various types of tempering.

Haley McAllister and Julia Kalow, with Northwestern University, have published a Perspective piece in the same issue of Science outlining the work.

Over the past several years, it has become evident that the use of plastics in products is harmful to not only the environment but also human health —bits of plastic have been found in the soil, the atmosphere, the oceans, and the human body.
