Hours after its successful launch at NASA’s Kennedy Space Centre in Florida on 23 April, the Dragon spaceship crew received a stark warning from the Pentagon about them being on a potential collision course with a mysterious space object.
The SpaceX craft seems to have had a near miss with an unidentified object while recently heading to the International Space Station, Futurism reported, adding that the four-strong crew was at one point warned of a potential collision with it.
The object, initially thought to be a grave threat to the crew and craft, as per Humphries, was mapped at a worrisome distance from the Dragon spacecraft – merely around 28 miles (45 km) away at its closest point.
In terms of space travel, it’s seen as dangerously close, especially given that there was no time to plan any evasive manoeuvres. Yet, the crew was ordered to put on their pressurised suits, which they had taken off by the time preparing to sleep.
Fortunately, the Dragon spacecraft and the object passed each other safely, and the SpaceX craft proceeded to the final destination, eventually docking with the ISS.
Space Junk Threat
The European Space Agency says there are about 128 million objects the size of 1 mm to 1 cm, 900,000 objects the size of 1 cm to 10 cm, and 34,000 objects over 10 cm in length currently whizzing about the Earth. Many of these chunks are travelling around our planet at roughly 28,163.52 kph, which is around 10 times faster than a bullet.
As senior NASA scientist Jack Bacon told Wired in 2010, the threat from space junk is real, as collision with just a small sphere of aluminium about 10 cm in size would be equal to detonating 15 pounds (7 kilograms) of TNT.
