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.

Galileo Survives Antenna Failure Through Ground-and-Software Rescue

When Galileo’s large high-gain antenna failed to deploy in 1991, NASA and the ground team rewrote onboard and ground software, upgraded the Deep Space Network, and compressed data to squeeze its flagship science through a low-gain antenna. The workaround let Galileo return substantial science from Jupiter (arriving in 1995 and operating until 2003), including studies of its atmosphere, Io’s volcanism, and evidence supporting a subsurface ocean on Europa, albeit at data rates far lower than originally planned.

Eagles vs Packers: Monday Night Football Preview and Updates

The Green Bay Packers vs. Philadelphia Eagles game on Monday Night Football may face broadcast issues due to a contract dispute between Disney (owner of ESPN and ABC) and YouTube TV. Fans can still watch the game via NFL+ streaming or over-the-air antenna, which are effective alternatives to cable or streaming services affected by the dispute.

Home Assistant Enhances Z-Wave Connectivity with New Adapter Launch

A large 12-inch Z-Wave antenna, the Home Assistant Connect ZWA-2, significantly improves smart home device connectivity over long distances, such as in gardens and attics, by using Z-Wave Long Range technology. It is easy to set up, enhances network stability, and is especially useful for connecting low-powered sensors and devices in remote areas of a property, despite its conspicuous size and appearance.

"Breakthrough: Physicists Invent Revolutionary Radio Wave Antenna"

Physicists at the University of Otago have developed a new form of antenna for radio waves using a small glass bulb containing an atomic vapor. The antenna, enabled by atoms in a Rydberg state, offers superior performance with high sensitivity, broad tunability, and small physical size. It eliminates the need for multiple antennas to cover different frequency bands and can be accessed via laser light, making it useful in defense, communications, and satellite technology. The portable design allows for field testing, and the researchers believe it will make quantum sensors more robust and cost-effective for real-world applications.

Comparing the Best Streaming Devices and Services for Free Local TV Channels

There are multiple options available for streaming local TV channels for free, including traditional methods like using an antenna or subscribing to cable or satellite services. However, there are also alternatives like cable TV replacement streaming services and network apps that require a paid TV login. Additionally, there are free options like Fox Local's suite of apps and LocalBTV. Different streaming devices, such as those running Google TV, Roku, or Apple TV, offer various features and app support, making them suitable for different user preferences.

Voyager 2 Reestablishes Contact with NASA

NASA's Voyager 2 spacecraft, launched in 1977 to explore far-away planets, has finally made contact after communication was lost two weeks ago due to a wrong command. The spacecraft, which is over 12 billion miles from Earth, sent a "carrier signal" indicating it is still operational. Engineers will attempt to turn the antenna back towards Earth, but if unsuccessful, they will have to wait until October when the spacecraft's onboard software resets its direction. Voyager 2's twin, Voyager 1, remains NASA's most distant spacecraft at 15 billion miles from Earth.

Voyager 2's Communication Lost: NASA's Mistake

NASA has announced that its Voyager 2 probe is currently unable to communicate with Earth due to a misalignment of its antenna, which has been pointing away from Earth for over a week. The probe, currently 32 billion kilometers away, is expected to recalibrate its position in October. This glitch does not affect Voyager 1, which is still in contact with Earth. Engineers are working to resolve the issue and extend the probes' working lives.

"Mastering OTA TV: 5 Expert Tips for Maximizing Your Antenna's Performance"

A cord cutter shares five pro tips for optimizing antenna reception: 1) Position the antenna high in a room or near a window for better signal; 2) Avoid placing the antenna behind the TV or near electronics and metal objects that can cause interference; 3) Consider using an amplifier to boost weaker signals; 4) Place the antenna as high as possible to overcome obstacles; 5) Choose the right antenna, and if needed, opt for an outdoor antenna for better reception. Additionally, using a DVR can enhance the antenna experience by allowing for streaming and recording of shows.
