Leonov’s First Spacewalk: The Silent Feed Cut and the Real Crisis

In 1965, Alexei Leonov became the first person to spacewalk during Voskhod 2, but mid-broadcast mission control cut the live feed as his suit ballooned in vacuum, forcing him to contend with a tricky return and a 12-minute outside excursion. The rest of the flight faced additional malfunctions and a difficult, off-target reentry, with rescue crews reaching them after days in harsh conditions. Publicly, the mission was framed as a success, but decades of evidence show extensive Soviet secrecy and crisis management around the near-disaster, and later analyses contrasted this with the more open NASA approach—shaping future spaceflight and contributing to the shift toward Soyuz.

ISS gains sun-watching telescope as Russians complete 6-hour EVA

Two Russian cosmonauts spent about six hours outside the ISS installing the Solntse-Teragerts sun-observing telescope on the Zvezda module, retrieving a semiconductor film sample from Nauka, inspecting a Kurs antenna, and completing multiple tasks. The telescope is designed to observe strong solar flares and run through 2028, while Kud-Sverchkov’s total spacewalk time rises to 12h11m and Mikaev records his first EVA; the outing also marked Energia’s 80th anniversary for Roscosmos.

Roscosmos cosmonauts set for five-hour ISS spacewalk

Two Russian cosmonauts, Sergei Kud-Sverchkov and Sergei Mikaev, will conduct a five-hour extravehicular activity outside the ISS to install a solar radiation experiment on the Zvezda module and remove hardware from Poisk and Nauka, with a possible photo of a Kurs antenna on Progress 94 if time allows. Coverage starts at 9:45 a.m. EDT (1345 GMT), with the EVA planned to begin around 10:15 a.m. EDT. Kud-Sverchkov has flown a spacewalk before, while Mikaev is on his first EVA; this is the second spacewalk of 2026.

NASA Spacewalk Photos Preview Next-Gen ISS Solar Arrays

NASA released photos from a March 18, 2026 spacewalk by Jessica Meir and Chris Williams to install a modification kit and brackets ahead of future roll-out solar arrays on the ISS 2A power channel, a seven-hour excursion that marked Meir's fourth spacewalk and Williams' first as they supported maintenance and upgrades for the station.

Satellite Delivers Stunning View of ISS During Spacewalk

A satellite operated by HEO Space captured a rare three-panel image of the International Space Station during a March 18 spacewalk by NASA astronauts Jessica Meir and Chris Williams outside the Quest airlock to prepare a new solar array; the photo, shared by HEO Space and later colorized for Reddit, underscores the growing role of satellites in high‑res space imagery and debris monitoring, with partners like BlackSky enabling multi-angle observations as orbital traffic expands.

Blob near ISS during spacewalk traced to radiator coolant, not alien life

During a spacewalk outside the International Space Station, astronauts spotted a mysterious ‘blob’ and were told to leave the area, but it was later identified as coolant leaking from a radiator. The leak was contained and the astronauts returned to the station. The article also notes the ISS’s long-term operation and a planned de-orbit in 2031.

ISS spacewalk delayed by medical evacuation, astronauts set to step outside today

NASA astronauts Jessica Meir and Chris Williams are slated to conduct a long-delayed spacewalk outside the International Space Station around 8 a.m. EDT today, after a SpaceX Crew-11 medical evacuation postponed an earlier EVA that would have involved Mike Fincke. The outing will prep a power channel for the future iROSA solar arrays, with live coverage beginning at 6:30 a.m. EDT.
