In the more than 60 years since the Space Age began, humans have sent more than 6,740 rockets to space. According to the ESA’s Space Debris Office, this has resulted in 56,450 objects in orbit; about 36,860 of these objects are regularly tracked and maintained in a catalog, while 10,200 are still functioning. The rest is a combination of spent rocket stages, defunct satellites, and pieces of debris caused by unused propellant exploding and orbital collisions. This is leading to a cascade effect known as Kessler Syndrome, where the amount of debris in orbit will lead to more collisions and more debris.

What’s worse, the situation is only projected to get worse since more launches are expected with every passing year. Last year, space agencies and commercial space companies conducted a record-breaking 263 launches, with the U.S. (158) and China (68) leading the way. And with future break-ups occurring at historic rates of 10 to 11 per year, the number of debris objects in orbit will continue to increase. According to a new study by a team from the University of British Columbia (UBC), this also means that debris falling to Earth will have a 1 in 4 chance per year of entering busy airspace.

SpaceX Starship Effectively Grounded by FAA After in-Flight Explosion

It was an exciting time when, two weeks ago, SpaceX got the clearance it needed to conduct its first orbital flight test with the Starship and Super Heavy launch system. After years of waiting, SN flight tests, static fire tests, and stacking and unstacking, the long-awaited test of the SN24 Starship and BN7 Booster prototype was on! For this flight, SpaceX hoped to achieve an altitude of at least 150 km (90 mi) above sea level, crossing the 100 km (62 mi) threshold that officially marks the boundary of “space” (aka. the Karman Line) and making a partial transit around the world before splashing down off the coast of Hawaii.

Unfortunately, things began to go awry a few minutes into the flight as the Starship prototype failed to separate from the booster, sending the rocket into a spin that ended in an explosion. While Musk and SpaceX issued statements that the test was largely successful and lots of valuable data was obtained, residents and environmental researchers claim the explosion caused damage to houses in the area and the local environment. In response, the FAA has launched a “mishap investigation,” temporarily grounding the Starship until the explosion’s impact can be assessed.

On Saturday, Sept. 28th, SpaceX founder Elon Musk presided over a media circus at their testing facility in Boca, Chica, Texas. With the fully-assembled Starship Mk.1 as his backdrop, Musk shared the latest updates on the Starship launch system, which include a timetable for when the first test-flights, commercial flights and crewed flights will commence. Sometime next year, he promised, it will begin taking passengers to space!
