ISS antenna swap set for spacewalk today by two astronauts

Two astronauts from NASA and ESA, Anil Menon and Sophie Adenot, are scheduled for a 6.5-hour spacewalk to replace a failed space-to-ground antenna on the International Space Station. The EVA is expected to start around 8:35 a.m. EDT on Aug. 25, 2026, and could include a backup task to replace a retroreflector on the Harmony module to improve navigation. Adenot becomes the first Frenchwoman to perform an EVA, while Menon will be on his third spacewalk. Coverage will be shown live via Space.com in partnership with NASA.

French spacewalker Adenot makes history, but antenna swap extended to next spacewalk

Sophie Adenot became the first French woman to spacewalk on Aug. 18, 2026, joining Anil Menon for EVA 97 to remove a failed Space-to-Ground antenna and install a replacement on the ISS’s Z1 truss. The pair completed the removal but ran out of time to finish the install because disconnecting cables and loosening bolts took longer than expected. Mission Control redirected the plan to secure the existing hardware and defer the antenna installation to a second spacewalk scheduled for Aug. 25. A working antenna continues to carry the data link in the meantime, illustrating how routine maintenance in space can consume more time than margins allow.

ISS spacewalk ends with failed antenna secured, spare installation delayed

During a six-hour, 23-minute ISS spacewalk, Anil Menon and Sophie Adenot removed a failed space-to-ground antenna, freed tight cables and attempted to secure it, but there wasn’t time to move the unit to storage or install the spare antenna; the failed antenna is lashed down near its boom while the replacement remains bolted to a storage platform, and a second spacewalk is planned next week to decide whether to install the spare then or defer the task; Adenot also becomes the first French woman to walk in space.

French spacewalker Adenot helps remove failed ISS antenna; replacement postponed

NASA astronaut Anil Menon and ESA's Sophie Adenot spent 6 hours 23 minutes outside the International Space Station to remove a failed Space-to-Ground antenna from the Z-1 truss; the crew successfully detached the faulty dish but were not able to install the replacement due to time, leaving the task for a future EVA and pending mission-control scheduling decisions. Adenot becomes France's first female spacewalker.

France's Sophie Adenot makes history with first Frenchwoman spacewalk at the ISS

French astronaut Sophie Adenot became the first Frenchwoman to perform a spacewalk from the International Space Station, joining Anil Menon for a six-and-a-half-hour EVA to replace a space-to-ground antenna and enhance data links to mission control in Houston; she is the second European woman to spacewalk, following Samantha Cristoforetti, marking another milestone for France in human spaceflight.

France’s Sophie Adenot to Make History with ISS Spacewalk

ESA astronaut Sophie Adenot will become France's first woman to spacewalk outside the ISS, partnering with NASA's Anil Menon for a roughly 6.5‑hour EVA to replace a space-to-ground antenna critical for communications; coverage begins Aug. 18 at 7 a.m. EDT on Space.com, and the outing marks the 282nd ISS spacewalk in history.

Mechanical Tracker Makes Pettit's Milky Way Shot Look Unreal

Astronaut Don Pettit's Milky Way image from the ISS drew skepticism about its realism, but he explained it was captured using a mechanical sidereal tracker on the Cupola to cancel the ISS's motion, turning stars into fixed points; the device, built by RIT, was later returned to the university.

Cybertrucks take over SpaceX Crew-13 escape duties

NASA and SpaceX will replace MRAPs with Tesla Cybertrucks as the emergency escape vehicles for Crew Dragon missions, starting with Crew-13 in September, to avoid resource conflicts with other launches and because Cybertrucks can exit the blast danger area faster; the Cybertrucks require no vehicle modifications beyond certification for EVA entry with spacesuits. Crew-13 will launch Sept. 12 aboard the Grace capsule, with NASA's Jessica Watkins (commander) and Luke Delaney (pilot), CSA's Joshua Kutryk, and Roscosmos's Sergey Teteryatnikov.

Cupola shot: ISS captures colossal Pacific typhoon in space

NASA astronaut Anil Menon photographed a massive typhoon swirling over the Pacific Ocean from the ISS cupola on Aug. 2, 2026, using an iPhone; the image highlights Earth’s power and shows how astronauts can capture stunning space‑born Earth photos, with the storm likely being Super Typhoon Dolphin, downgraded to a category 3 as it heads toward Okinawa. The piece also notes ongoing advances in astronaut photography and mentions NASA’s plan to retire the ISS around 2030.

Milky Way from Orbit: Astronaut Shares Stunning ISS Photo

Astronaut Don Pettit shared a Milky Way image captured from the International Space Station’s Cupola, taken with a Nikon Z9 and ARRI Zeiss 15mm lens using a sidereal drive to cancel star motion; he says it’s one of his favorite Milky Way shots and has just received 1.2 million raw files from his latest mission, sparking widespread awe on social media.

Sixteen Sunrises a Day: NASA’s Lighting Fight to Reset the Astronaut Clock

The ISS orbits Earth every ~92 minutes, giving astronauts 16 sunrises and 16 dusks per Earth day, which disrupts their natural circadian clocks and leads to sleep loss and reduced cognitive performance. NASA combats this with LED lighting that shifts color and intensity to cue wakefulness or promote sleep, and by covering windows during rest to minimize real-time light cues. A 2016 study of 21 long-duration astronauts found they averaged about 6 hours sleep per night (vs. ~7 on Earth), with many using sleep meds and experiencing circadian misalignment that correlated with decreased performance during critical tasks. Despite engineering advances, spaceflight remains hard on the human body, and lighting alone has not fully solved the sleep-and-clock challenge for astronauts.

Orbiting daylight: how the ISS keeps a human day with engineered light

With ~90-minute orbits yielding 16 sunrises and sunsets each day, the ISS keeps a 24-hour rhythm not by the Sun but by UTC scheduling, window management, and a smart lighting system that shifts from day (neutral/blue-enriched) to pre-sleep (warm) and alertness (cool). Astronauts still average about six hours of sleep, using sleep shifts when needed; future missions will rely even more on engineered daylight since there may be no Earth sunrise to cue the body.

Boeing's Starliner Poised for a 2026 Return, Pending ISS Port and Propulsion Fixes

On Boeing’s earnings call, CEO Kelly Ortberg said Starliner’s propulsion deficiencies are being redesigned and are progressing well. The next mission is a cargo flight to the ISS, with the launch date dependent on NASA port availability; if this goes smoothly, a crewed Starliner mission could follow in late 2027, though Boeing has already booked roughly $2 billion in charges for delays and fixes. Starliner competes with SpaceX’s Crew Dragon, which is currently cheaper and more reliable, and future costs for human spaceflight in the 2030s are likely to rise.

Daylight Duel: ISS and Venus Captured Together by AJ Smadi

Astrophotographer AJ Smadi captured a daytime image of the International Space Station passing Venus near Seattle on July 18, 2026, using a 9.25-inch Celestron SCT and a ZWO ASI662MC with UV/IR filters. The feat, achieved in daylight with careful planning, follows Smadi’s earlier success and echoes NASA’s recognition of his work in Astronomy Picture of the Day, highlighting how challenging and rare it is to photograph these two celestial bodies side-by-side in daylight.
