WASHINGTON (NASA PR) — NASA and SpaceX signed an unfunded Space Act Agreement Thursday, Sept. 22, to study the feasibility of a SpaceX and Polaris Program idea to boost the agency’s Hubble Space Telescope into a higher orbit with the Dragon spacecraft, at no cost to the government.

NASA to Set Up Independent Study on Unidentified Aerial Phenomena

WASHINGTON (NASA PR) — NASA is commissioning a study team to start early in the fall to examine unidentified aerial phenomena (UAPs) – that is, observations of events in the sky that cannot be identified as aircraft or known natural phenomena – from a scientific perspective. The study will focus on identifying available data, how best to collect future data, and how NASA can use that data to move the scientific understanding of UAPs forward.

The limited number of observations of UAPs currently makes it difficult to draw scientific conclusions about the nature of such events. Unidentified phenomena in the atmosphere are of interest for both national security and air safety. Establishing which events are natural provides a key first step to identifying or mitigating such phenomena, which aligns with one of NASA’s goals to ensure the safety of aircraft. There is no evidence UAPs are extra-terrestrial in origin.

PARIS (ESA PR) — Combining artificial intelligence with many keen human eyes, astronomers have found 1,701 new asteroid trails in archival data from the NASA/ESA Hubble Space Telescope, consisting of more than 37,000 images that span two decades. The project reflects both Hubble’s value to scientists as an asteroid hunter and how the public can effectively contribute to citizen science initiatives.

PARIS (ESA PR) — ESA’s exoplanet mission Cheops has revealed that an exoplanet orbiting its host star within a day has a deformed shape more like that of a rugby ball than a sphere. This is the first time that the deformation of an exoplanet has been detected, offering new insights into the internal structure of these star-hugging planets.

The planet, known as WASP-103b is located in the constellation of Hercules. It has been deformed by the strong tidal forces between the planet and its host star WASP-103, which is about 200 degrees hotter and 1.7 times larger than the Sun.

Hubble Space Telescope Passes 1-Billion Second Mark

NASA Mission Update GREENBELT, Md. (NASA PR) — On Jan. 1, 2022, NASA’s Hubble Space Telescope officially passed the one-billion second mark. Hubble was deployed from the Space Shuttle Discovery’s cargo bay on April 25, 1990, making it one-billion seconds (over 31 years) since Hubble began operating. For more than three decades, Hubble has provided us with groundbreaking scientific discoveries and iconic images of space. Hubble’s first one-billion seconds included five astronaut servicing missions to replace […]

NASA’s 2021 Achievements Included Mars Landing, First Flight, Artemis, More

WASHINGTON (NASA PR) — In 2021, NASA completed its busiest year of development yet in low-Earth orbit, made history on Mars, continued to make progress on its Artemis plans for the Moon, tested new technologies for a supersonic aircraft, finalized launch preparations for the next-generation space telescope, and much more – all while safely operating during a pandemic and welcoming new leadership under the Biden-Harris Administration.

Hubble Finds Evidence of Persistent Water Vapor in One Hemisphere of Europa
This photograph of the Jovian moon Europa was taken in June 1997 at a range of 776,700 miles by NASA’s Galileo spacecraft. Slightly smaller than Earth’s moon, Europa has a very smooth surface and the solid ice crust has the appearance of a cracked eggshell. The interior has a global ocean with more water than found on Earth. It could possibly harbor life as we know it. Hubble Space Telescope observations of Europa have revealed the presence of persistent water vapor in its very tenuous atmosphere. Hubble observations, spanning 1999 to 2015, find that water vapor is constantly being replenished throughout one hemisphere of the moon. This is a different finding from Hubble’s 2013 observations that found localized water vapor from geysers venting from its subsurface ocean. This water vapor comes from a different process entirely. Sunlight causes the surface ice to sublimate, transitioning directly into gas. This color composite Galileo view combines violet, green, and infrared images. The view of the moon is shown in natural color (left) and in enhanced color designed to bring out subtle color differences in the surface (right). The bright white and bluish part of Europa’s surface is composed mostly of water ice, with very few non-ice materials. Long, dark lines are fractures in the crust, some of which are more than 1,850 miles long. The Galileo mission ended on Sept. 21, 2003, when the spacecraft was intentionally commanded to dive into Jupiter’s atmosphere, where it was destroyed. However, to this day scientists continue to study the data it collected. The Jet Propulsion Laboratory (JPL) in Pasadena, California managed the Galileo mission for NASA’s Office of Space Science, Washington, DC. JPL is an operating division of California Institute of Technology (Caltech). This image and other images and data received from Galileo are posted on the Galileo mission home page. Background information and educational context are also available for the images. (Credits: NASA, NASA-JPL, University of Arizona)

GREENBELT, Md. (NASA PR) — NASA’s Hubble Space Telescope observations of Jupiter’s icy moon Europa have revealed the presence of persistent water vapor – but, mysteriously, only in one hemisphere.

STRASBOURG, France (Europlanet Society PR) — An international team of astronomers has not only detected clouds on the distant exoplanet WASP-127b, but also measured their altitude with unprecedented precision. A presentation by Dr Romain Allart at the Europlanet Science Congress (EPSC) 2021 shows how, by combining data from a space- and a ground-based telescope, the team has been able to reveal the upper structure of the planet’s atmosphere. This paves the way for similar studies of many other faraway worlds.

NASA Successfully Switches to Backup Hardware on Hubble Space Telescope

BALTIMORE (NASA PR) — NASA has successfully switched to backup hardware on the Hubble Space Telescope, including powering on the backup payload computer, on July 15. The switch was performed to compensate for a problem with the original payload computer that occurred on June 13 when the computer halted, suspending science data collection. The switch included bringing online the backup Power Control Unit (PCU) and the backup Command Unit/Science Data […]
