A new privately financed camera recently mounted on the International Space Station to bring high-resolution space scenes to the public captured spectacular views of the Crew Dragon after it docked at the station's forward port.

A day after launching from the Kennedy Space Center, a SpaceX Crew Dragon spacecraft caught up with the International Space Station and moved in for docking Sunday, bringing a NASA astronaut and a Russian cosmonaut to the outpost to join Then, during another Starlink launch on Aug. 28
, a Falcon 9 first stage descending to toward landing crashed onto the deck of an off-shore drone ship. SpaceX has not provided any information about what went wrong or what, if any, corrective actions were required, but flights resumed three days later.
SpaceX provided no details about the off-target re-entry of the Crew Dragon’s upper stage other than the post late Saturday on X.
The nozzle of the Falcon 9’s second stage Merlin engine glows red while boosting the Crew 9 spacecraft to the planned orbit for a rendezvous with the International Space Station. The firing went well and the Crew Dragon capsule was safely sent on its way. But the second stage malfunctioned during a subsequent engine firing to drive the rocket into the atmosphere.

Going into Saturday’s launch, SpaceX was planning to launch 20 OneWeb broadband satellites from Vandenberg Space Force Base in California this week, followed by a Starlink launch from Cape Canaveral. Both flights are now on hold.
More important, a Falcon 9 will be used to launch the European Space Agency’s $390 million Hera asteroid probe from the Cape Canaveral Space Force Station around Oct. 7, followed by launch of NASA’s $5.2 billion Europa Clipper Jupiter probe from the Kennedy Space Center on Oct. 10.
Hera is bound for the asteroid Didymos and its moon Dimorphos, a small body that NASA’s DART probe crashed into in 2022. Hera will study the system in detail to determine how the moon’s structure and orbit were changed by the impact. A primary goal is to learn more about how an asteroid threatening Earth some day might be safely diverted.
The Europa Clipper is a “flagship” mission to explore Jupiter’s ice-covered moon Europa and to determine the habitability of a vast sub-surface ocean. It is the largest planetary probe ever built, requiring a powerful Falcon Heavy rocket, made up of three strapped-together Falcon 9 first stages and a single upper stage, to send it on its way.
Both missions must get off the ground during relatively short “planetary” launch windows defined by the positions of Earth, Mars, Jupiter and the asteroids. Hera’s window opens on Oct. 7 and closes on Oct. 25. The Europa Clipper launch window opens on Oct. 10 and runs through Nov. 6.
Missing a planetary window can result in long, costly delays while while Earth, Jupiter, the asteroids and Mars, needed for gravity assist flybys, return to favorable orbital positions enabling launch.
Armando Piloto, a senior manager with the Launch Services Program at the Kennedy Space Center, said the Falcon Heavy stages used for the Europa Clipper mission will not be recovered. Instead, they will consume all of their propellants to achieve the velocity needed to send the probe on a five-year voyage to Jupiter.
“I’ll point out that during the burn of the second stage, the vehicle with the spacecraft, will be traveling approximately 25,000 miles per hour, which will be the fastest speed for a Falcon second stage ever for Europa Clipper,” he said during a recent briefing.
Given SpaceX’s rapid recoveries after the July and August malfunctions, the upper stage re-entry anomaly Saturday presumably will be resolved in time to get the Europa Clipper and Hera missions off the ground within their launch windows. But that will depend on the results of the latest failure investigation.
