A shiny new SpaceX Falcon 9 rocket on Thursday successfully lofted the latest military satellite to space for the US Space Force.

Elon Musk’s rocket company finally launched the third-generation military GPS satellite after a series of earlier delays. It was initially set for blastoff in late September but then got pushed back a few days. It came close to lifting off Oct. 2, but the launch was aborted with just two seconds to go on the countdown clock.

The unexpected issue led to a few other delays, notably of NASA’s Crew-1 mission to send four astronauts to the International Space Station aboard a SpaceX Crew Dragon capsule, out of concern that the issue could crop up on other Merlin engines.

SpaceX launches GPS navigation satellite with repaired Falcon 9 rocket

Recovering from a last-second October 2 launch abort, SpaceX successfully fired off the same Falcon 9 rocket Thursday night, boosting a third-generation Global Positioning System navigation satellite into orbit for the U.S. Space Force.

The nine Merlin 1D engines in the rocket’s first stage, including two replacement engines, roared to life at 6:24 p.m. ET, pushing the slender 229-foot-tall Falcon 9 away from pad 40 at the Cape Canaveral Air Force Station atop a brilliant jet of flaming exhaust.

The engines appeared to operate flawlessly as the rocket climbed out of the thick lower atmosphere, putting on a spectacular evening sky show as it raced past a rising Mars and lined up on a northeasterly trajectory paralleling the East Coast.

GPS and water don’t mix. So scientists have found a new way to navigate under the sea

Nearly half a century ago, the US Department of Defense started working on a project to pinpoint locations on the surface of the planet thanks to satellites. What is now known as GPS has since come a long way, permeating every aspect of our everyday lives, from helping city-dwellers find their way through unknown streets all the way to assisting the delivery of emergency services.

And yet even today’s most sophisticated GPS systems are still unable to map a huge chunk of the Earth: that which is located under oceans, seas, or rivers. The technology, in effect, doesn’t mix well with water, which breaks down the radio waves GPS relies on to function. 

MIT scientists have been looking at ways to create a new type of underwater GPS, which could be used to better understand the mysteries that lie between surface and seabed. The researchers have now unveiled a device

SpaceX and Space Force set to launch long-delayed GPS mission

SpaceX

More than a month after a last-second scrub, SpaceX says it’s now ready to launch the latest US Space Force mission atop a Falcon 9 rocket later this week.

The payload is a third-generation military GPS satellite that was initially set for blastoff in late September but then got pushed back a few days. It came close to launching on Oct. 2, but the launch was aborted with just two seconds to go on the countdown clock.

The unexpected issue led to a few other delays, notably of NASA’s Crew-1 mission to send four astronauts to the International Space Station aboard a SpaceX Crew Dragon capsule, out of concern that the issue could crop up on other Merlin engines.

Einstein’s theory of relativity, critical for GPS, seen in distant stars

Einstein's theory of relativity, critical for GPS, seen in distant stars
The intriguing system known as 4U 1916-053 contains two stars in a remarkably close orbit. One is the core of a star that has had its outer layers stripped away, leaving a star that is much denser than the Sun. The other is a neutron star, an even denser object created when a massive star collapses in a supernova explosion. The neutron star (grey) is shown in this artist’s impression at the center of a disk of hot gas pulled away from its companion (white star on left).

What do Albert Einstein, the Global Positioning System (GPS), and a pair of stars 200,000 trillion miles from Earth have in common?


The answer is an effect from Einstein’s General Theory of Relativity called the “gravitational redshift,” where light is shifted to redder colors because of gravity. Using NASA’s Chandra X-ray
