Shortly after entering orbit on April 23, astronauts aboard the SpaceX Dragon were told to prepare for a possible collision with an unknown object. With no time to make evasive maneuvers, the astronauts scrambled in their pressure suits, and viewers on Earth watched in shock at what might come next. Oops! Turns out the whole fiasco was just a false alarm.
According to US Space Command, Crew-2 astronauts aboard the SpaceX Dragon were not endangered by rogue space junk, debris, a rock, aliens or other flying objects. Some reports suggest that an object flew within 25 miles of the capsule, but this measurement has not been confirmed by NASA. It is still unclear what the object was, how close it got to the capsule, and whether it existed at all.
Several news outlets share a video, shown above, in which a large circular object flies near the capsule. This video was actually taken before the near collision false alarm incident and shows a chunk of SpaceX missile debris tumbling through the void. It was not a threat to the crew.
Space Command investigates the false alarm to find out what went wrong. Collision with foreign objects is a serious threat in space, and even a small piece of debris or space rock can tear through a capsule on impact. Fortunately, the Crew-2 astronauts are safe and arrived at the ISS shortly after this incident took place. They will stay there for about 6 months before returning to Earth.
