just outside my studio, roots of trees and shrubs rip circles through cement;
this is a view of that–time rippled, space condensed.

How It Works: The Most Powerful Space Rocket
When the firm SpaceX launches its Falcon Heavy rocket into space late this year, the craft will become the mightiest rocket in the world. Only NASA’s Saturn V, which sent Americans to the moon, has ever generated more power. In rockets, the most important measure of power is thrust. Falcon Heavy’s 27 individual booster engines together generate 3.8 million pounds of thrust—enough to lift the 3.1-million-pound rocket and its 117,000-pound payload toward low-Earth orbit. The rocket’s success is critical for both SpaceX and the U.S. space program: The Air Force has already hired SpaceX and its Falcon Heavy to send two satellites into orbit sometime in 2015.

Nine SpaceX Merlin 1D engines sit at the bottom of each of the craft’s three cores, or boosters. The engines are identical to those on SpaceX’s Falcon 9 rocket.

Falcon Heavy’s first stage consists of three cores. All three cores operate together at liftoff. About T+2:45 minutes into flight, the center core throttles down while the two side cores continue at full thrust until their fuel is nearly spent. At that point, pneumatic separators release the side cores, which plummet into the ocean, and the center core throttles up.

For payloads heavier than 100,000 pounds, Falcon Heavy uses a cross-feed system to run fuel from the side cores to the center core, leaving the center core almost fully fueled after the side boosters separate. What’s left is the equivalent of a complete Falcon 9 rocket already high in space.

A liquid-oxygen tank at the top of each core feeds the engines through a center tube; the lower portion of the tank contains rocket-grade kerosene. The propellants are turbo-pumped into each Merlin engine’s injector, where they are mixed and fed into the combustion chamber.

Powered by a single Merlin 1D engine modified to operate in the vacuum of space, the second stage delivers the final push that gets the payload into orbit. The engine can shut down and reignite as needed, enabling Falcon Heavy to deliver multiple payloads to different orbits.

Falcon Heavy can carry either a Dragon capsule—SpaceX’s free-flying spacecraft, currently used to resupply the International Space Station—or up to 117,000 pounds of payload (think multiple military and commercial satellites) enclosed in a shell 45 feet long and 17 feet in diameter. The fairing consists of two clamshell-style halves made of an aluminum honeycomb core and carbon-fiber face sheets. When the second stage nears the desired orbit, pneumatic pushers split the halves apart, exposing the payload.

A single Merlin 1D generates 147,000 pounds of thrust at sea level, burning rocket-grade kerosene and liquid oxygen fed by a turbo-pump into the combustion chamber. Falcon Heavy’s liquid propellant has an advantage over solid fuel: Liquid-fueled engines can stop and restart in flight, whereas solid-fuel engines burn until they are spent. Through proprietary adjustments that SpaceX won’t disclose, engineers recently lightened the engine to increase its efficiency, making it the most efficient rocket booster engine ever built.

T – 3:00:00
Falcon Heavy is ready on the launch­pad at Cape Canaveral. Engineers time liftoff to achieve the optimal flight path and desired orbit.

T – 0:10:30
The countdown begins. All actions from here forward are pre-programmed, although Mission Control can abort the mission at any time.

T – 0:02:30
The launch director issues the final launch command.

T – 0:00:40
Propellant tanks are pressurized.

T – 0:00:03
First-stage engines ignite.

The onboard rocket computer commands the launch mount to release. Liftoff.

T + 0:01:25
The rocket reaches maximum aerodynamic pressure; mechanical stress peaks.

T + 0:02:45
The rocket has now burned enough fuel (thus decreasing its mass) that the center core engines can throttle down.

T + 0:03:00
The side cores separate and fall into the ocean, while the center core’s nine Merlin engines continue to burn for approximately 30 seconds.

T + 0:03:30
The second stage separates from the remaining first-stage core. The second-stage engine ignites and continues toward orbit.

T + 10–20 MINUTES
When the rocket nears the desired orbit, the two halves of the clamshell fairing open and fall away. When in position, the payload separates from the second stage. Both the fairing and second stage eventually fall back to Earth.

Total Thrust: 3.8 million pounds
Maximum Payload: 117,000 pounds
Number of Engines: 28
Size of the Fairing: 45 feet by 17 feet in diameter

NOTE: The SpaceX Falcon Heavy will be the world’s most powerful rocket when it launches later this year. It can carry a payload of up to 117,000 pounds in its clamshell fairing. The fairing is shown here (image 2) open with the payload exposed, but on a mission it would remain closed until the first stage has separated and the second stage has nearly reached orbit. credit: Nick Kaloterakis
Elon Musk wants to create ‘superhero astronauts’: SpaceX hires Marvel costume designer to make a spacesuit for Mars
The billionaire recently hired Marvel costume designer Jose Fernandez. The California-based designer is better known for designing costumes for films such ‘Captain America: Civil War’.

Mars astronauts could look more like superheroes - at least, that’s if Elon Musk gets his way.

The billionaire recently hired Marvel and DC movie legend Jose Fernandez to design a spacesuit for his firm, SpaceX.

Fernandez is better known for designing costumes for superheroes in films such as ‘Batman vs. Superman’ and ‘Captain America: Civil War’.

Fernandez took inspiration from Musk himself, when creating the costume for Iron Man, as Tony Stark is modeled on the billionaire.

A Tested video and a Bleep interview recently revealed the Fernandez is designing a ‘stylish’ and ‘heroic’ alternative to Nasa’s Z-2, spacesuit design.

Engadget reports that we are unlikely to see the suit until sometime in the next year.

Elon Musk Unveils The Hyperloop!

A year after floating the idea of improving public transportation, Space X and Tesla Motors founder Elon Musk has unveiled the Hyperloop!

The solar-powered city-to-city transit system would take passengers and cars from Los Angeles to San Francisco in just 30 minutes.

The Hyperloop would transport people via aluminum pods enclosed inside of steel tubes. The tubes are mounted on columns spaced 50 to 100 yards apart and the pods inside would travel up to 800 mils per hour. On top of all of this, the pods would be able to ferry cars as well as people. Musk states:

“You just drive on, and the pod departs.”

The Hyperloop comes just as Musk grew disenchanted with the plans for California’s high speed rail system which he felt was costly, slow, and inefficient. The Hyperloop’s suspended nature would also avoid many land rights issues since farmer’s would still be able to access their land between the columns and would follow along the already existing I-5 freeway.

As far as safety is concerned, the safe distance between pods would be about 5 miles, leaving room for 70 pods in the tubes at once. Each pod has an emergency break and would have less lateral acceleration, which it what tends to make people motion sick.

The tube system is designed to link cities less than 1,000 miles apart that have high amounts of traffic between them. Musk elaborates:

"It makes sense for things like L.A. to San Francisco, New York to D.C., New York to Boston. Over 1,000 miles, the tube cost starts to become prohibitive, and you don’t want tubes every which way. You don’t want to live in Tube Land.”


Do you think the Hyperloop is a viable transportation option? Why or why not? Let us know in the comments down below!


Video: Grasshopper reaches new record height.

The reusable rocket from Space X reached a height of 1,066 feet during testing in June, after having a new navigation sensor fitted to assist in landing.

The company hopes to one day use the technology to send paying customers into orbit, and return them safely to the same launch pad.


SapceX’s Falcon Heavy is the most powerful rocket in the world

When SpaceX’s Falcon Heavy rocket launches later this year, it will be the largest operational rocket in the world. Its debut could mark a major shift in commercial spaceflight because it will be the only reusable, and therefore cheaper (if SpaceX can reliably land and relaunch it) heavy-lift rocket available for contract. Here’s everything you need to know about it.
