Spinning Membrane Space Telescopes Would Be Big, Cheap and Easy

Robert Zubrin has proposed using rotating membranes to create Enormous Space Telescopes (ESTs) that can scale to over 1000 meter diameter or match current space telescopes for thousands of time lower cost. They would also not require the construction of large structures. A demonstration cubesat EST could have an aperture larger than the Webb Space …

ESA Ariel Space Telescope Will Survey Atmospheres of 1000 Exoplanets Starting in 2029

ESA’s exoplanet mission Ariel, scheduled for launch in 2029, has moved from study to implementation phase, following which an industrial contractor will be selected to build the spacecraft. Ariel, the Atmospheric remote-sensing infrared exoplanet large-survey mission, addresses one of the key themes of ESA’s Cosmic Vision programme: What are the conditions for planet formation and …

Carnival of Space 639 – 75 Temporary Moons Should Be Detected Over the Next Ten Years

The Carnival of Space 639 is up at Urban Astronomer. Universe Today – The Large Synoptic Survey Telescope Could Find More of Earth’s Transient Moons. Earth also has a population of what are known as “transient Moons”. These are a subset of Near-Earth Objects (NEOs) that are temporarily scooped up by Earth’s gravity and assume …

Path to Detecting All Blackholes in the Universe All the Time

Gravity Wave detections are rapidly increasing. The first gravity wave was detected in 2015. The science needed to accomplish this is described in the Veratasium videos below. They needed to create single wavelength lasers and use one-megawatt of power to detect differences of one trillionth of a wavelength. Gravitational-wave astronomy is a completely new way …
