Navigation Satellites fly at 23,000 km Altitude. Europe Wants to Build a Constellation That Flies Much, Much Lower

   02 Nov 20:00:14  |  Universe Today

Distances to different orbits can be hard to understand. For example, the ISS sits around 400 kilometers from Earth, whereas some satellites, such as Starlink, orbit at about 550 km. Often that is intentional, as objects in those orbits will eventually degrade their orbit and burn up in Earth’s atmosphere. However, many systems orbit a …

NASA?s new Glider Could Turn any Airport Into a Spaceport

   02 Nov 20:00:14  |  Universe Today

Getting to space has almost always been a multi-stage process. Those stages typically took the form of different stages of chemical rockets, but it doesn’t have to be that way. Plenty of alternative options have been proposed, and one that NASA has been working on for almost a decade is getting closer to commercialization. The …

In a New Hubble Image, Dark Matter Anchors the Giant Galaxy Cluster Abell 611

   31 Oct 20:00:03  |  Universe Today

Dark matter. It’s secret. It’s dark because it doesn’t give off any light. We can’t see it, taste it, touch it, smell it, or even feel it. But, astronomers can measure this dark secret of the universe. How? By looking at galaxies and galaxy clusters. Dark matter exerts a gravitational influence on those regions, and …

InSight Felt the Ground Shake From a Meteorite Impact on Mars

   30 Oct 20:00:04  |  Universe Today

The Mars InSight lander might be nearing the end of its life on the Red Planet, but its scientific data are still shaking up the planetary science community. That’s because it detected another Marsquake on December 24, 2021. It was a major shaker and generated surface waves that rippled across the crust of the planet. …

Will Enceladus finally answer, ?Are we alone

   30 Oct 20:00:03  |  Universe Today

We recently examined how and why the planet Mars could answer the longstanding question: Are we alone? There is evidence to suggest that it was once a much warmer and wetter world thanks to countless spacecraft, landers, and rovers having explored?and currently exploring?its atmosphere, surface, and interior. Here, we will examine another one of Saturn?s …
