Air Force Secretary Frank Kendall in a keynote speech Sept. 20 warned that China’s rapid advances in nuclear and conventional weapons will challenge the United States both in the air and space domains.
Increasingly capable satellites are driving demand for more complex thermal management solutions to keep them from overheating as they work harder, according to heat pipe manufacturer Advanced Cooling Technologies (ACT).
Diplomats and other experts see signs of progress at the United Nations on addressing space sustainability but caution it may will take many years before any sort of binding agreement emerges.
A draft environmental assessment released by the Federal Aviation Administration suggests that SpaceX will be able to proceed with orbital Starship launches from Texas, but with a number of mitigations required.
The growing number of satellites in orbit is leading to calls to develop formal “right of way” rules, although there is no consensus on what those rules should be and how they should be established.
The ground stations and tracking antennas the U.S. military relies on to communicate with its satellites — known as the Satellite Control Network, or SCN — are decades old and short of the capacity needed to keep up with the projected growth in space activities.
CesiumAstro expects to be building satellites mostly by itself in two years to house the active phased arrays it has been developing, aiming to shift the paradigm for electronically steered antennas with commercial-like industrialization processes that lower costs and speed up production.
Two years after the close approach of a Starlink satellite with a European Space Agency satellite alarmed some in the space industry, SpaceX says it’s working closely with a wide range of satellite operators to ensure safe space operations.
Space situational awareness data used by satellite operators isn’t accurate enough to support the decisions they need to make on whether and how to maneuver their spacecraft to avoid potential collisions.
Under a new agreement with U.S. defense contractor Peraton, OneWeb’s satellite communications services will be more widely available to military users in hard-to-reach areas, including ships at sea.
NASA says its VIPER rover will head for the western edge of Nobile Crater near the moon’s south pole in 2023, targeting a region where shadowed craters are cold enough for water ice to exist, but where enough of the sun’s rays reach to keep the solar-powered robot going. Today#et##8217;s announcement provides a focus for …

The night sky is a part of humanity’s natural heritage. Gazing up at the heavens is a unifying act, performed by almost every human that’s ever lived. Haven’t you looked up at the night sky and felt it ignite your sense of wonder? But you can’t see much night sky in a modern city. And …

Even meteorologists who forecast the weather on Earth admit that they can’t always accurately predict the weather at a specific location on our planet any given time. And so, attempting to forecast the atmospheric conditions on another world can be downright impossible. But a new study suggests that an oft-used forecasting technique on Earth can …

The Moon’s pitted surface tells a tale of repeated impacts over a long period of time. While Earth’s active geology erases most evidence of impacts, the Moon has no mechanism that can do the same. So there it sits, stark evidence of an impact-rich past. The visible record of lunar cratering is used to understand …

Understanding the birth of a planet is a challenging puzzle. We know that planets form inside clouds of gas and dust that surround new stars, known as protoplanetary disks. But grasping exactly how that process works – connecting the dots between a dust cloud and a finished planet – is not easy. An international team …

Thinking outside the box has always been a strong suit of space exploration. Whether taking a picture of the Earth in a sunbeam or attempting to land a rocket on a floating ship, trying new things has been a continual theme for those interested in learning more about the universe. Now, a team from the …

Dust devils are generally used as a trope in media when the writers want to know that an area is deserted. They signify the desolation and isolation that those places represent. Almost none of the settings of those stories are close to the isolation of Perseverance, the Mars rover that landed on the planet earlier …

History has viewed mining as a job that requires a lot of heavy machinery and physical labor. Pulling valuable material out of the ground has been necessary for human progress for thousands of years. That progress has led to an alternative method of getting those resources out of the Earth or other celestial bodies. The …
