The last time I put my #luggage in an old-fashioned #suitcase, I lifted it too rapidly after check-in because I was in a hurry to catch my flight, and my #massive #manly #musculature propelled it upward so fast it punched a hole in the #airport roof. Air traffic control lost track of it at the #Karman line where it was still traveling at considerably more than escape velocity. It's probably somewhere in the #asteroid belt by now. So I'll stick to the wheeled variety. Just safer for everybody.

✈️ #Aurora will be capable of flying at very high speeds (of up to Mach 3.5 km/h) and of reaching suborbital altitudes beyond the #Karman line 🌌. #DawnAerospace stated that it expects commercial deliveries of the ‘Aurora’ to start in 📆 2027 https://www.aerotime.aero/articles/dawn-aerospace-starts-accepting-orders-for-aurora-suborbital-aircraft

#spaceplane

"Everybody’s going to know if you paid to be a passenger on a five-minute #suborbital flight or if you’re the commander of an interplanetary #space vehicle.”

100 kilometers is how the Swiss-based World Air Sports Federation defines the #Kármán line.

Experiencing #weightlessness has little to do with altitude. It's a minutes-long version of the sensation people experience when they reach the peak of a big roller-coaster 🎢 hill

Clutter in space presents an imminent threat to human activity at or above the #Kármán #line,
the altitude at which conventional aircraft can no longer fly
—about 62 miles (100 kilometers) above the surface.

As more objects are launched into orbit, the possibility of #catastrophic #collisions increases.

More frequent collisions increase the volume of debris, thereby raising the odds of another collision.

Like a traffic jam, eventually the area becomes so congested that nothing can move safely.

The minimum speeds necessary to achieve orbit are very high,
thus everything up there moves extremely fast.

Basic physics teaches that the faster an object moves, the higher energy it carries into an impact scenario.

For this reason, even tiny morsels pack a devastating punch.

For example:
An object 10 cm wide (3.9 inches) packs the same force as 7 kg (15.4 lbs.) of TNT.
With limited ability to conduct repairs and collect debris,
the problem worsens with each occurrence.

Decades ago, a NASA physicist calculated how this situation can eventually devolve into disaster.

He determined that putting low earth orbit (where most human-made objects reside) into such a state of chaos will lead to space travel
—manned or unmanned
—eventually becoming impossible.

This principle is now called the #Kessler #Syndrome.

✧ Theodore von Kármán ✧

Theodore von Kármán (1881–1963) was a Hungarian-American mathematician, aerospace engineer and physicist who worked in aeronautics and astronautics. He was responsible for crucial advances in aerodynamics characterizing supersonic airflow. The human-defined threshold of outer space is named the Kármán line in recognition of his work.
