Martin Halliwell is a Partner at NewSpace Capital, one of the world's first private equity firms devoted exclusively to growth-stage companies working in the space technology sector. He formerly served as Chief Technology Officer of SES, where he led global technology and R&D from 2011 to 2019. Halliwell contributed this article to Space.com's Expert Voices section. There are now some 16,000 active satellites in orbit. Market intelligence firms like Novaspace say that up to 43,000 satellites will be built and launched over the coming decade. Others, such as Goldman Sachs, think as many as 70,000 new low-Earth orbit (LEO) satellites could be launched in the next five years alone. The exact number is less important than what these predictions reveal: that satellite constellations are getting bigger. This is a good thing. Space is a crucial enabling force in the modern world, touching ...

Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy. from Latest Science News -- ScienceDaily https://ift.tt/N6i3JeA

While Hardspace: Shipbreaker does an excellent job of capturing the dystopian perils of unchecked hypercapitalism, the real fun in this space game comes from carving up massive capital ships with space lasers and explosives. Floating in zero gravity, players slice derelict spacecraft into salvageable chunks, while also contending with unruly physics, pressure, and profit margins. It's a compelling fantasy: orbital blue-collar labor, where yesterday's spacecraft become tomorrow's raw materials. As satisfying as the simulation is, the real-world challenge of space debris removal is both more constrained and more urgent. (Image credit: Blackbird Interactive) Christian Steimle is the Project Manager of the European Space Agency 's (ESA) ClearSpace-1 mission, the first ever aimed at removing a piece of debris (in this case, a satellite called PROBA-1) from low-Earth orbit. We spoke ...

German startup Rocket Factory Augsburg (RFA) just put the brakes on its first launch. While testing its RFA One rocket on the launch pad at the U.K.'s SaxaVord Spaceport on the Shetland Islands in Scotland, the company found "an issue with the vehicle that requires further investigation," RFA wrote on X on Wednesday (July 28). Previously, the launch had been expected to happen in August or September , but RFA did not disclose a new launch date. RFA did not disclose the nature of the issue, but said it would de-stack the staged rocket and that it would provide more details as the investigation continues. The situation means that the U.K. will need to wait at least a few more weeks to attempt its first-ever vertical launch from the region, amid global constraints in launch capacity and calls for increased European spaceflight autonomy . RFA One , a smaller rocket designed to launch ...

The excitement of the new moon mission has potentially helped create a new generation of stargazers, just like the Apollo program did 60 years ago. These new observers will be looking for a beginner’s telescope that is easy to use and which can show them the craters on the moon in particular. The Celestron Moon Mission 100mm Tabletop Dobsonian could be the perfect entry point for them. It has a superb price-point for its aperture, and is capable of bringing not only the moon, but double stars, the brighter galaxies and nebulas and the moons of Jupiter to your backyard. The Celestron Moon Mission 100mm Tabletop Dobsonian comes equipped with 8mm and 20mm eyepieces, one of which is intended specifically for the moon, as well as a red-dot finderscope, a moon filter, a moon-map poster and free access to download the Starry Night planetarium software and Celestron’s SkyPortal app, which is powered by S...
