Even though solid boosters are more efficient than liquid engines, SpaceX does not use solid boosters, because their distinctive technology then creates more expense. By sticking to just one tech (liquid engines only), they save on the cost of supporting multiple technologies.

Remember, Falcon Heavy hasn't flown yet, so don't bet the farm on something that hasn't even flown (of course, neither has GSLV-Mk3)

But SpaceX has a lot of NASA scientists helping them behind the scenes. US govt is backing them, because it has no choice but to go with private launchers, now that Shuttle is gone. That International Space Station was really a big mistake - such a huge money-sucker. Think of all the things that could have been done instead.

I think that Indian govt should similarly privatize PSLV by spinning it off the private sector. They can then charge those private launch companies for tech support on their proven workhorse launcher, which they have gathered a lot of knowledge and experience on. Private companies might even be able to tinker with the PSLV design, to incrementally improve it over time, and push it to greater limits.

Meanwhile, ISRO could focus its main attention on GSLV and turning it into the proven workhorse, instead of resting on its laurels and still trying to seek praise over "200th shuccesshful PSLV launch! No GSLV yet, but we have had long string of good PSLV launches! Yayyyyy!":wacko:

Then once GSLV is proven, it could be spun off to the private sector yet again, etc.

Launch vehicles in US are all Private, Lockeed, Boeing, Martin all of them are private corporations.

Funny thing is this private company is more advanced than ISRO, its falcom 9 can lift of more than GSLV3. The only difference between GSLV 3 and F-9 is that the F-9 does it with no huge boosters like GSLV-3, imagine how advanced it is!

Matter of fact the none of the falcon rockets require boosters, they fly only with internal fuel! That is super advanced, we would only catch up in 2030.
Well we cant always aurgue competing "My Balls are Bigger than yours" right!!!

The Falcon-9 is still a Paper Work. Even We and Iranians and can come up with a better Imagination.
Your di@k has two boosters! This is what happens if you have porn in your next tab, it will resemble what you saw last! :D

The rocket has the same shape as the p@nis for the same reason, for smooth penetration through the atmosphere!
Lol,.......Well thats some sort of scientific reason alright.

The bulge at the tip of most rockets is to accomodate payloads with bigger diameter than the main rocket.
Excatly,.........The Bigger the rocket the Bigger the Tip. Right Kafir:becky:

That would End up has a Monopoly in Space Transport for SpaceX:mad2::frusty:

At start i thought the company is wasting a lot of money investing on these Rockets now i realized the fact. Competition has come to the space industry. When the Falcon-9 vehicle is operational, Everyone will be looking to contact SpaceX. US could earn lot of money on this.

You cannot trust Indian corporates not to sell the technology to anyone for a right price.

People like Ambanis will not bat an eyelid in doing so. Not everyone is a Tata.

GSLV-3 with boosters can lift 4,500kgs!

Falcon-9 with booster can lift 54,000kgs! :D
Correction: Falcon Heavy (as yet unbuilt) is spec'd to lift 54,000kg and not Falcon-9.

Meanwhile, here is an August 1st keynote address by Elon Musk at the American Institute of Aeronautics and Astronautics:

There would have to be strict accountability, obviously. Tata Aerospace could be a good candidate.

Having multiple launch providers could create another low-cost-high-engineering marketplace for Indians to excel in, just like IT.
Given that the most vigorous sector of India's economic growth has been in engineering services, low-cost Indian brains could bring about a revolution in the marketplace.

ISRO needs to get out of its playpen to build and launch much bigger and better rockets, instead of deteriorating into laziness and stagnation of doing the same things over and over again.

The density and intensity of it all. Sending spacecrafts and satellites into space has become a weekly occurance :rofl:

China sends two satellites into space

English.news.cn 2011-11-20 11:08:13


A Long March 2D carrier rocket carrying Chuangxin 1-03 and Shiyan Satellite 4 blasts off from the launch pad at the Jiuquan Satellite Launch Center in northwest China's Gansu Province, Nov. 20, 2011. The launch was the 151th of China's Long March series of rockets. The Chuangxin 1-03 will be used to collect and relay hydrological, meteorological, and electric power data as well as data for disaster relief. The Shiyan Satellite 4 will be used for space technology experiments and environmental observation. (Xinhua/Gong Lei)


BEIJING, Nov. 20 (Xinhua) -- China on Sunday morning put two satellites into orbit from the Jiuquan Satellite Launch Center in northwest China's Gansu Province.

The satellites, Chuangxin 1-03 and Shiyan Satellite 4 were launched on a Long March 2D carrier rocket at 8:15 a.m. Beijing Time, said a Xinhua photographer, who witnessed the whole process.

The Chuangxin 1-03, developed by the Chinese Academy of Sciences, will be used to collect and relay water conservancy, hydrological and meteorological data and data for power supply and disaster relief from monitoring stations.

The Shiyan Satellite 4 will be used for experiments on space technologies and environment probe. Developed by the Chinese Research Institute of Space Technology, it is the country's fourth technology experiment satellite.

The launch was the 151th of China's Long March series of rockets. The Long March-2D is one of the derivations of Long March-2.

China started development of modern carrier rockets in 1956, and Long March rockets have become the main carriers for China's satellite launching.

Private Company Launches Rocket with Payload for ISS

SpaceX's Dragon capsule on way to the Space Station
First commercial flight to orbital outpost lifts off, just days after initial launch abort
MSNBC By Clara Moskowitz
May 22, 2012





CAPE CANAVERAL, Fla. — A private space capsule called Dragon soared into the predawn sky Tuesday, riding a pillar of flame like its beastly namesake on a history-making tripto the International Space Station.

The unmanned capsule, built by billionaire entrepreneur Elon Musk's Space Exploration Technologies Corp. (SpaceX), is the first non-governmental spacecraft to launch to the space station, ushering in a new era of partnership between the public and private spaceflight programs.

"I think this is an example of American entrepreneurship at its best," said Alan Lindenmoyer, manager of NASA's commercial crew and cargo program, in a briefing before the launch. About 100 VIP guests were on hand to witness the launch, NASA officials said.

The Hawthorne, Calif.-based SpaceX launched its Dragon capsule at 3:44 a.m. EDT Tuesday from a pad here at the Cape Canaveral Air Force Station. It blasted off atop SpaceX's Falcon 9 rocket, a 157-foot (48-meter) booster powered by nine Merlin rocket engines. The space station was flying 249 miles above the North Atlantic Ocean as the rocket lifted off, NASA officials said.

Private spaceship in orbit

The gumdrop-shaped capsule is 14.4 feet tall (4.4 meters) and 12 feet wide (3.7 m), and packed with 1,014 pounds (460 kilograms) of cargo for the space station, including 674 pounds (306 kg) of foodand supplies for the crew, as well as student-designed science experimentsand a laptop computer.

The Falcon 9 rocket's second stage is also reportedly carrying ashes from 308 people, including actor James Doohan, who played Scotty on the 1960s television series "Star Trek," and Mercury program astronaut Gordon Cooper. The ashes were flown under a deal with the "memorial spaceflight" company Celestis, according to ABC News and Reuters. The ashes were in a section of the rocket that was jettisoned during the climb into space, The Associated Press reported.

The SpaceX launch vehicle is named after the Millennium Falcon of "Star Wars," while the capsule got its moniker from the Peter, Paul and Mary song, "Puff, the Magic Dragon."

Today marked only the second-ever launch of a Dragon capsule, and the third flight for the Falcon 9 rocket. It was the second attempt to launch the space station-bound test flight after a launch try Saturday was thwarted by a faulty rocket engine valve. Repairs were made over the weekend, and the SpaceX team counted down smoothly to the liftoff this morning.

"One thing that they are very good at is being able to work through launch abort and treat those problems and be prepared to go again in a very short time," Mike Horkachuck, NASA project executive for SpaceX, said Monday.

Today's launch is the last planned test flight for SpaceX under NASA's Commercial Orbital Transportation Services (COTS) program intended to develop a private-sector replacement for the cargo-delivery services of the retired space shuttles. SpaceX has a $1.6 billion contract to fly at least 12 unmanned missions to the space station through 2015.

Musk founded SpaceX in 2002 with the goal of boosting commercial access to space and, ultimately, aiming for deep-space exploration, including missions to Mars. The success of today's launch was never certain or assured, Musk had repeatedly said.

Today, the mission's uncertainty eased up a bit, he said.

"Falcon flew perfectly!!" Musk wrote in a Twitter post from Falcon 9's mission control room in Hawthorne. "Dragon in orbit, comm locked and solar arrays active!! Feels like a giant weight just came off my back."

Orbital catch up

The spacecraft is due to spend its first day on orbit catching up with the 240-mile high (390 km) space station, where it will rendezvous Thursday and perform a fly-by to within 1.5 miles (2.5 kilometers) to check its navigation systems.

On Friday, the capsule is slated to perform a series of maneuvers to approach the station, with crew members onboard the outpost issuing commands to Dragon. If the spacecraft passes a set of "go-no go" checks at Mission Control in Houston, NASA will approve the vehicle to approach the International Space Station. From inside, astronauts Don Pettit and Andre Kuipers will use the lab's robotic arm to grab Dragon and berth it to the station's Harmony node.

The hatches between the two spacecraft are due to be opened early Saturday, so the crew can enter Dragon and unpack its payload.
Dragon is due to spend about a week attached to the outpost. On May 31, the capsule will be packed with completed science experiments and other equipment, unberthed and sent back toward Earth. The vehicle is equipped with a heat shield to withstand the fires of re-entry, and is due to splash down and be recovered by ship in the Pacific Ocean.

Private spaceflight reality

Dragon is an unmanned version of a capsule ultimately intended to carry people as well.

Another company, Orbital Sciences Corp. of Dulles, Va., also has a NASA contract to deliver cargo to the space station, and plans to launch its first test flight later this year.

The program is part of a larger effort by NASA to outsource low-Earth orbit transportation to the private sector, allowing the space agency to begin work on a new spacecraft and heavy-lift rocket to visit asteroids, the moon and Mars.

The plan has received criticism from some lawmakers and members of the public, who worry that commercial vehicles aren't as safe or reliable as NASA's in-house built spacecraft.

"It's really easyto criticize, and it's very difficult to solve a problem and actually do something," said SpaceX President Gwynne Shotwell. "So I tend to focus on the business and getting our jobs done and not focus on those that want to criticize."

NASA officials and leaders of the commercial space sector say the time is right for space to transition from an exclusively government regime to an arena open to private companies.

"I kind of see that transition as being inevitable," said Phil McAlister, NASA's director of Commercial Spaceflight Development. "I believe it
is going to happen at some point. If it's not today and this mission falls short of expectations, it is going to happen eventually."

This thread is for Falcon Heavy while my thread was about the first mission to the ISS of the Dragon capsule. The former is still conceptual while the latter is already realized. I don't the threads should be merged.

A robotic arm on the International Space Station has reached out to grab the visiting Dragon supply vessel. The arm will shortly move the ship to a free berthing port on the underside of the orbiting platform.

Dragon has been built by the California firm SpaceX and is carrying half a tonne of food and other stores for the ISS astronauts.

Falcon Heavy Could be Launched by 2013

SpaceX signs Intelsat as first Falcon 9 Heavy customer
By: ZACH ROSENBERG
SpaceX signs Intelsat as first Falcon 9 Heavy customer


SpaceX has announced that major communications satellite operator Intelsat is the first customer for its Falcon 9 Heavy, essentially three-core, 27-engine version of the Falcon 9 rocket capable of launching up to 53,000kg into Earth orbit.

"SpaceX is very proud to have the confidence of Intelsat," says Elon Musk, chief executive of SpaceX. "The Falcon Heavy has more than twice the power of the next largest rocket in the world. With this new vehicle, SpaceX launch systems now cover the entire spectrum of the launch needs for commercial, civil and national security customers."

The first launch pad for the Heavy is under construction at Vandenberg Air Force Base, California, the preferred site for polar-orbit launches. The company also hopes to launch from NASA's Kennedy Space Center (KSC), Florida, from which the Falcon 9 currently flies.

Intelsat notes that the timing and launch site are still under discussion but that the launch will not take place from Vandenberg AFB, which will be the site of the first Falcon 9 Heavy launch in mid-2013. This suggests that the flight will likely take place at either SpaceX's facilities at KSC or a new launch site in Brownsville, Texas, after 2013 because there are no other Falcon 9 Heavy pads that are near completion.



"Intelsat has exacting technical standards and requirements for proven flight heritage for our satellite launches," says Intelsat chief technology officer Thierry Guillemin. "We will work closely with SpaceX as the Falcon Heavy completes rigorous flight tests prior to our future launch requirements."

Intelsat declined to share additional details, citing ongoing negotiations. SpaceX was unable to respond to immediate questions.
