Algorithm to Improve Reconstruction Exoplanet Images from Gravity Lensing

Going beyond physical limitations of telescopes, Stanford University astrophysicists have been working on a new conceptual imaging technique that would be 1,000 times more precise than the strongest imaging technology currently in use. By taking advantage of gravity’s warping effect on space-time, called lensing, scientists could potentially manipulate this phenomenon to create imaging far more …

Megapixel Exoplanet Imaging in Weeks not Years via Gravitational Lens Missions

Slava G. Turyshev and his team are on their phase III NASA NIAC project to develop a solar gravitational lens telescope. At optical or near-optical wavelengths, the amplification of light is on the order of 200 billion times and with equally impressive angular resolution. If we can reach this region beginning at 550 AU from …

2022 Should See Start of Technology Demos Leading to High Resolution Exoplanet Imaging

A NASA NIAC Phase III is developing and plans to fly a 2022 TDM (Technology Demonstration Mission) to prove the SGLF’s (Solar Gravitational Lens Focus) mission architecture. They will then prepare a near-term (by 2024), low-cost (less than $40M) mission to fly through the solar system faster than any spacecraft ever ~7 AU/year, capable of …

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 …
