Giant disco ball to plummet back to Earth

  Giant disco ball to plummet back to Earth <p>The party is coming to an end, and much sooner than anticipated.</p>The Humanity Star, a reflective satellite launched by private company Rocket Lab, is expected to flame out sometime this week. Launched in New Zealand in January, it had been expected to keep us looking to the skies for the majority of 2018.

SpaceX 's rocket , however, was carrying such a light payload (Formosat-5 weighed just 1,047 pounds) that it could and did take a near-vertical path. The ionosphere hole didn't cause much chaos by itself.

Researchers have determined that a Falcon 9 launch in August 2017 (the Formosat-5 mission above) not only created circular shockwaves, but cut a 559-mile hole in the plasma of the ionosphere that lasted for up to 3 hours -- it was akin to a localized magnetic storm. The phenomenon was produced by virtue of the rocket's light payload.

As Ars Technica noted, most rockets have a curved trajectory to reduce the effect of gravity and alleviate stress. SpaceX's rocket, however, was carrying such a light payload (Formosat-5 weighed just 1,047 pounds) that it could and did take a near-vertical path. Think of it as dropping a rock in the water instead of skipping it -- you're going to create a much bigger splash.

The ionosphere hole didn't cause much chaos by itself. However, more frequent and more powerful launches with these kinds of disruptions could significantly skew GPS navigation. Rocket operators may have to watch their launches going forward to be sure they don't play havoc with phones and cars on the ground below.

SpaceX launches reused cargo ship to space station .
A SpaceX Dragon cargo ship bound for the space station will deliver nearly 3 tons of supplies and equipment into space for a two-day flight to the International Space Station. Equipped with a previously flown first stage and a Dragon cargo capsule making its second flight to the lab complex, the Falcon 9 thundered away from pad 40 at the Cape Canaveral Air Force Station at 4:30:38 p.m. EDT (GMT-5), climbing directly into the plane of the station's orbit.
