ESA's Proba-3 Coronagraph re-establishes contact after month-long silence

ESA says its Proba-3 Coronagraph spacecraft has reconnected with Earth after a month of silence; an anomaly in February disrupted attitude control and prevented safe-mode entry, and the spacecraft is now in safe mode with its solar panels powering the systems while health checks are conducted to assess possible damage as the Coronagraph and its Occulter continue their formation to study the solar corona by creating artificial eclipses.

Proba-3 falters as ESA’s twin-satellite eclipse mission goes dark

Europe’s Proba-3 formation (two satellites designed to create artificial solar eclipses and study the corona) has lost contact after an anomaly caused one probe to lose orientation. The Coronagraph, which images the sun’s outer atmosphere, and its Occulter partner must stay precisely aligned about 150 meters apart; the incident has led to a progressive attitude loss and solar-power drain, pushing the spacecraft into survival mode. ESA says the root cause is under investigation and teams are exploring ways to steer the Occulter closer to the Coronagraph to diagnose the issue and reestablish contact, with updates expected as the investigation continues (reported after Feb. 14 anomaly, with March 6 ESA update cited).

James Webb Telescope Achieves Historic Direct Imaging of Its First Exoplanet

The James Webb Space Telescope has made its first direct detection of an exoplanet, TWA 7b, a Saturn-like planet orbiting a young star, using advanced imaging techniques. This breakthrough allows astronomers to study faint planets and their atmospheres, opening new avenues in exoplanet research.

NASA's Roman Telescope Prepares to Hunt for Exoplanets

NASA's Nancy Grace Roman Space Telescope has successfully integrated the Roman Coronagraph Instrument, a key component designed to block starlight and detect faint light from exoplanets. This marks a significant step towards the telescope's 2027 launch, where it will explore dark energy, exoplanets, and infrared astrophysics. The coronagraph, a technology demonstration, aims to improve direct imaging of exoplanets, paving the way for future missions like the Habitable Worlds Observatory, which will search for Earth-like planets.

"Studying the Sun: Artificial Solar Eclipses Unveil Scientific Insights"

Scientists are attempting to create an artificial solar eclipse to study the solar corona, a layer of the sun's atmosphere with significant effects on Earth. Using specialized instruments called coronagraphs, they aim to simulate eclipses and view the corona, which is mysteriously hotter than the solar surface. Despite challenges such as Earth's atmosphere scattering sunlight, scientists are conducting experiments to better understand the corona, including a forthcoming European Space Agency mission called Proba-3. The upcoming total solar eclipse on April 8 will provide a scientific bonanza for researchers, who are preparing to gather data using various instruments and techniques, including a citizen science project called Citizen CATE.

NASA Prepares for Launch of Next Generation Flagship Space Telescope

NASA is already planning for its next flagship space telescope, the Habitable Worlds Observatory (HWO), which could serve as the successor to the James Webb Space Telescope (JWST). The HWO aims to study exoplanets, stars, galaxies, and other celestial objects for signs of life beyond Earth. The Technical Assessment Group (TAG) for HWO, consisting of 56 individuals, will focus on developing key technologies and design requirements. The HWO is expected to launch in the late 2030s or early 2040s and will utilize a coronagraph to block out starlight and analyze exoplanet atmospheres for potential biosignatures.

"Searching for Alien Life: The Quest for Extraterrestrial Civilizations"

Scientists and engineers at Caltech are discussing the development of the Habitable Worlds Observatory (HWO), a proposed space telescope that aims to detect signs of life on exoplanets. The HWO would be the next powerful astrophysics observatory after NASA's James Webb Space Telescope and would have the ability to study stars, galaxies, and exoplanets. The telescope's ability to characterize exoplanet atmospheres and search for biosignatures depends on advanced technologies such as coronagraphs, which block the glare from distant stars. The HWO mission is expected to launch in the late 2030s or early 2040s, and scientists hope to have a catalog of at least 25 Earth-like planets to explore by then.
