Astronomers discover a giant, rocky 'mega-Earth' 23 times more massive than our planet

• NASA has canceled the "Swift Boost" mission, which was intended to extend the operational life of the Swift space observatory. • As a result of the cancellation, the observatory will eventually re-enter Earth's atmosphere and burn up.

• A $30 million private rescue mission intended to save NASA's Swift Observatory has failed, leaving the telescope destined to crash back to Earth. • The Swift telescope, which has provided critical data on gamma-ray bursts, will now re-enter the atmosphere and be destroyed later this year.

• NASA and Katalyst Space announced Wednesday that the LINK spacecraft will no longer capture or boost a NASA satellite to a higher altitude due to an ongoing attitude control issue. • The original goal was to extend the science mission of the Neil Gehrels Swift Observatory by moving it to a higher orbit.

• NASA and Katalyst Space Technologies announced on Wednesday that the mission to save the Swift space telescope has been officially called off. • The effort was intended to rescue the telescope, which was described as "sinking" or facing critical failure.

• NASA has launched the Orbital Clarity Challenge, the sixth installment in the TechLeap Prize series, in collaboration with the agency's Heliophysics Division and Flight Opportunities program. • The challenge seeks innovative technical solutions to improve orbital clarity and data acquisition for space-based observations.

• NASA's Perseverance rover captured images of a solar eclipse occurring on the surface of Mars. • The event occurred as one of Mars' moons passed between the planet and the Sun, partially blocking the sunlight.

• The National Science Foundation (NSF) has announced $1.5 billion in funding dedicated to science and engineering research. • The agency is implementing more flexible grant structures specifically designed to support emerging research and long-term projects.

• Several federal agencies are facing significant shifts, including NOAA withdrawing support for the Arctic Report Card and the DOJ declaring certain NSF programs unconstitutional. • The NIH is proposing to replace numerical peer-review scores for grant proposals with qualitative labels such as “most competitive” or “not discussed.”

• Astronomers have discovered three supermassive black holes on the verge of colliding within a single distant galaxy. • The galaxy dates back to a period less than 1.3 billion years after the Big Bang, indicating an unusually high concentration of black holes for its size.

• NASA has captured images of a new lunar crater created after a defunct component of a SpaceX Falcon 9 rocket crashed into the moon. • The rocket part struck the lunar surface uncontrolled this month, traveling at an estimated speed of 5,400 mph.

• European Space Agency astronaut Sophie Adenot is scheduled to perform a spacewalk today, August 18. • This mission marks a historic milestone as Adenot becomes the first French woman to ever conduct a spacewalk.
