The Nancy Grace Roman Space Telescope is four days from liftoff on a Falcon Heavy from Kennedy Space Center, with its Launch Readiness Review set for Friday and Sunday as the target launch date. Roman is a flagship NASA observatory built to map dark energy across billions of years of cosmic expansion and detect exoplanets via gravitational microlensing — capabilities that directly complement the James Webb Space Telescope at the L2 orbital point.

Meanwhile, NASA astronaut Anil Menon and ESA astronaut Sophie Adenot are conducting a second spacewalk at the International Space Station to complete antenna installation on the Z1 truss — a task that ran out of time on August 18th. That earlier excursion marked a milestone: Sophie Adenot became the first French woman to perform an EVA.

On the solar front, an M6.9 flare from sunspot region 4513 has prompted NOAA to issue G1 and G2 geomagnetic storm watches for August 27th and 28th, with aurora possible at higher latitudes. SpaceX, separately, announced a $100 billion investment in a new 125,000-acre spaceport in Vermilion Parish, Louisiana, with a first launch targeted for 2029. The company also confirmed that the August 26th Vandenberg Starlink mission was the last planned Falcon 9 Starlink flight from Florida — future missions move to Starship.

NASA's NIAC program selected 18 Phase One concepts sharing $3.2 million, covering ideas from femtosatellites at Saturn to Venus-hardened spacecraft. And tonight through tomorrow, a 96.2% partial lunar eclipse is visible across the Americas — the deepest until December 2028.
