The chief of space operations of the U.S. Space Force Gen. Chance Saltzman, told lawmakers at a recent hearing that the service is struggling with the math on satellite refueling. And we can’t blame him.  Congress has been advised many times of the national security imperatives for launching constellations to low Earth orbit (LEO) as

When people trade stocks, they don’t always learn from experience Bill Ross/Getty Images Even when we learn from past mistakes, we may never become optimal decision-makers. The finding comes from an analysis of a mathematical game that simulates a large economy, and suggests we may need to rethink some of the common assumptions built into

KISSIMMEE, Fla. — The head of the National Reconnaissance Office’s commercial space office Pete Muend announced plans to create a flexible contracting pipeline to onboard the latest innovations from private remote sensing companies. Speaking at the GEOINT Symposium, Muend said commercial imagery is needed to complement national systems and meet the growing demands from the

Visualisation of a protein binding to a DNA molecule Science Photo Library/Alamy An artificial intelligence system can now determine not only how proteins fold but also how they interact with other proteins, drug molecules or DNA. Biochemists and pharmaceutical researchers say the tool has the potential to vastly speed up their work, such as helping

Leaders of the National Reconnaissance Office, the U.S. government agency responsible for designing, building, launching and maintaining America’s intelligence satellites, often cite their commitment to commercial purchases. “Buy what we can and build what we must” is the agency’s long-standing strategy, NRO Director Chris Scolese said in 2022 when the agency awarded contracts worth $4

Sperm whales seem to communicate with sequences of clicks Amanda Cotton Sperm whale calls are far more complex than we thought – and could be an animal communication system that is the closest thing to human language yet discovered. The claim is based on an analysis of thousands of exchanges made by east Caribbean sperm

Kissimmee, Fla. – Airbus will continue to improve sensors in its Pleiades Neo Next constellation rather than duplicating the capabilities of the two Pleiades Neo satellites in orbit. “We are committed to continuing and to enhancing this constellation,” Eric Even, Airbus Defence and Space head of integrated space solutions, told SpaceNews. Airbus established the Pleiades

Previously, physicists theorised that black holes are the fastest possible scramblers of information MARK GARLICK/SCIENCE PHOTO LIBRARY/Alamy When two quantum objects interact, all the information they carry becomes scrambled. Now, physicists have calculated a fundamental limit for how quickly this can happen. One striking example of information scrambling happens in black holes, says Victor Galitski

KENNEDY SPACE CENTER, Fla. — Even a successful crewed test flight of Boeing’s CST-100 Starliner vehicle could create a temporary hiccup in plans to exchange seats between commercial crew vehicles and Soyuz spacecraft going to the International Space Station. At a May 3 briefing here, NASA and Boeing officials said they had completed a launch

The 54th anniversary of the Apollo 13 mission – which saw the successful return of its crew back to Earth after a disaster onboard the spacecraft – occurred in mid-April. It remains one of the great examples of the human spirit and ingenuity triumphing over seemingly insurmountable odds. It is also one of the great

Red squirrels can carry bacteria that cause leprosy Karin Greevy/Shutterstock The DNA of leprosy-causing bacteria has been found in the remains of people and a red squirrel unearthed at medieval sites in the UK. This makes red squirrels the earliest known non-human hosts of the infection and suggests it may have spread between the rodents
