A YouTube simulation translates Voyager 1's ~38,000 mph velocity into an Earthbound scenario, highlighting its status as the farthest human-made object and its long-running mission, with contact likely fading after around 2036 as it drifts beyond Earth’s Deep Space Network.
NASA moved the Artemis II SLS rocket off the launch pad at Kennedy Space Center and rolled it back to the Vehicle Assembly Building for additional repairs, delaying readiness ahead of the crewed lunar mission.
NASA disclosed that astronaut Mike Fincke experienced a medical issue during SpaceX's Crew-11 mission to the ISS that required urgent attention not available on the station, prompting an early return of all four Crew-11 crewmates—Fincke, Zena Cardman, Kimiya Yui and Oleg Platonov—aboard Endeavour on Jan. 15. The exact ailment was not disclosed, but it necessitated advanced medical imaging on Earth. The Crew-11 return left a skeleton crew aboard the ISS until Crew-12 arrived, and Fincke is recovering at NASA's Johnson Space Center after landing as mission planners adjusted Crew-12's launch to maintain operations.
NASA veteran astronaut Mike Fincke said a medical event forced Crew-11 to end its ISS mission early, with the crew returning to Earth for advanced medical imaging not available on the station. NASA has not disclosed details due to privacy rules, and Crew-12 later joined the station to restore seven-person staffing as NASA pushes Artemis-era exploration.
NASA astronaut Mike Fincke, ISS commander, disclosed he experienced a medical event in January that led to a carefully planned early return for Crew-11. NASA said the step was to use advanced medical imaging available on Earth rather than indicate an on-station emergency. Fincke and crewmates Zena Cardman, Kimiya Yui and Oleg Platonov landed Jan. 15 off San Diego; others remained on Earth for follow-up. Fincke is recovering at NASA’s Johnson Space Center with care from NASA, SpaceX and medical staff, including treatment at Scripps Memorial Hospital La Jolla.
NASA revealed that astronaut Mike Fincke suffered a medical event on the International Space Station in January, triggering the space station's first medical evacuation in 25 years and an early return of Crew-11 for advanced medical imaging and evaluation, with Fincke stabilizing and thanking the crew and medical teams.
Astronaut John Glenn reported thousands of tiny, luminescent particles swirling around his Friendship 7 capsule during the 1962 Earth orbit, prompting NASA concern about potential impact. The “fireflies” were later explained as sun-illuminated ice particles, a phenomenon confirmed on later flights.
NASA will roll the Space Launch System and Orion back to the Vehicle Assembly Building for repairs after a helium-flow blockage was found in the upper stage, delaying Artemis II’s planned March moon mission to at least April; the 322-foot rocket will be transported slowly on a crawler-transporter, and engineers will replace batteries and the flight termination system as they investigate the issue following a wet dress rehearsal.
Artemis II astronauts will carry two Nikon D5 DSLRs from 2016 into the Moon’s vicinity to document the mission, along with personal devices and GoPros for a National Geographic documentary; NASA highlights the D5’s low noise, wide dynamic range, and radiation tolerance as reasons for its selection, while future Artemis missions may use newer cameras. A helium-system issue has delayed the launch to at least April.
NASA has rolled back the Artemis II rocket to the Vehicle Assembly Building after a helium-flow problem in the upper stage of the Space Launch System, delaying a March liftoff. Engineers are investigating the cause while officials consider potential April launch windows, with further testing likely. When/if it launches, Artemis II will carry four astronauts on a 10-day lunar flyby, marking the first deep-space mission since Apollo ended in 1972.
NASA plans to roll the Artemis II SLS rocket and Orion back from the Kennedy Space Center launch pad to the Vehicle Assembly Building to repair a helium‑flow issue that halted recent tests, delaying the first crewed lunar mission and threatening the April launch window while engineers diagnose the root cause.
NASA will stream the undocking and departure of SpaceX’s CRS-33 Dragon from the ISS, with undock at 12:05 p.m. ET and splashdown off the California coast around 11:44 p.m. PST. The Dragon carries thousands of pounds of crew supplies, science samples and hardware from investigations such as Euro Material Ageing, Stellar Stem Cells Mission 2, SpaceDuino and Moon Microscope, and it also demonstrates a reboost capability to help maintain the station’s orbit. Coverage begins at 11:45 a.m. ET on NASA+, Amazon Prime, and YouTube, marking another step in ISS operations ahead of NASA’s Artemis-focused deep-space program.
NASA plans a slow rollback of its Artemis moon rocket to Kennedy Space Center's Vehicle Assembly Building to diagnose a helium-system issue after hydrogen-leak fixes, a move that could preserve an April launch window for Artemis II if repairs go well and data supports it; the four astronauts are in Houston awaiting the decision.
In May 1969, Apollo 10 crew Stafford, Young and Cernan achieved the fastest human speed on reentry—36,397 ft/s (about 39,937 km/h)—during their lunar-return trajectory. The record endures because no crewed mission has left Earth orbit since Apollo 17, and subsequent flights have not surpassed that reentry velocity. Artemis plans aim to return humans to the Moon with comparable speeds, but thus far only the uncrewed Artemis I reentry reached about 39,400 km/h, keeping Apollo 10’s speed record intact as a landmark of lunar-flight physics.
NASA's Space Launch System rocket for the Artemis II crewed Moon mission is back in the hangar for repairs after a helium-system issue, following hydrogen-leak fixes; engineers will diagnose the problem at Kennedy Space Center, with an April launch still possible though timing remains tight. The four-person crew—three Americans and one Canadian—remains on standby as NASA works to resolve the issues before the first crewed lunar flight since Apollo.
