SpaceX’s Falcon Heavy Launches on 3rd Mission

The world’s strongest working rocket took flight once more early on Tuesday morning.

SpaceX’s Falcon Heavy blasted off from Kennedy Space Center in Florida, the third journey to area for the rocket. Its 2018 take a look at launch lofted founder Elon Musk’s Tesla roadster into the photo voltaic system, and a second mission in April carried a Saudi communications satellite tv for pc to orbit.

This time it’s carrying 24 satellites for the Defense Department and different clients, and Mr. Musk referred to as it SpaceX’s “most difficult launch ever.” A successful mission could lead to additional business from the United States government for Falcon Heavy.

The blast off occurred at 2:30 a.m. Eastern time during the last hour in the four-hour launch window. Local authorities warned the public in Florida to expect loud noise from the rocket’s launch and landing attempts.

A week after launch, the massive sails will spread out and begin using sunlight to lift the cubesat into a higher orbit. The goal is to reach 450 miles above Earth, which would make LightSail-2 the first solar sail to use only the power of sunlight to enter a high orbit. It would then orbit Earth for about a year.

“We’ve made all sorts of vital and very significant improvements to the spacecraft. So I’m very excited about this.” said Bill Nye, the “science guy” and chief executive of the Planetary Society.

Proving the technology works would have significant implications for the future of deep space exploration. When robotic space explorers launch, they carry limited fuel. But solar sailing could provide an alternative propulsion method with nearly limitless fuel, improving the prospects of exploring the farthest reaches of our solar system, or even possibly a journey to other stars.

A NASA payload, this small satellite is a test of rocket fuel that is more environmentally friendly.

Most spacecraft use a propellant called hydrazine, which is highly toxic. To even be near hydrazine, a person must wear a protective Hazmat suit.

This new, less toxic fuel is made of a hydroxyl ammonium nitrate fuel/oxidizer blend, called AF-M315E that was originally developed by the Air Force but never used in space. Not only does this green propellant pose less of a threat to humans handling it, but it’s also more efficient.

To track missions in deep space, NASA and other space agencies rely on radio signals, waiting for them to traverse the long distances. Robotic probes constantly call home to Earth to confirm the current time and their location. But space agencies need a more timely way to track their spacecraft and their future human missions.

Atomic clocks track vibrations inside an atom like cesium, to measure time accurately. Aboard Global Positioning System satellites orbiting Earth, atomic clocks help precisely triangulate distances traveled over periods of time. But the technology has never been used in deep space. If the Deep Space Atomic Clock is tested successfully, future missions in deep space could navigate the solar system with something like GPS.

One of SpaceX’s major selling points for those who need to go to space — including the United States military, NASA and private companies — is the cost-effectiveness of the company’s reusable rockets.

The company has landed the booster stages of many rockets, and then reused them. That will also occur with this launch. Its side boosters landed in April; it’s the first time the Defense Department has allowed its hardware to be launched aboard a previously used rocket.

After Falcon Heavy’s launch, SpaceX will attempt to land all three boosters back on Earth. The rocket’s two side boosters will touch down at about the same time at Kennedy Space Center, which the company has already done twice. Landing the center booster is more difficult, and the Heavy failed on its first landing attempt aboard a drone ship in the Atlantic Ocean in 2018. But it touched down successfully in April.

While the floating landing platform ship, named Of Course I Still Love You, was 25 miles off the coast of Florida for that return, it will be over 700 miles away this time.
