World's Most Powerful Rocket Ready in 2012, SpaceX Says

World's Most Powerful Rocket Ready in 2012, SpaceX Says

The era of the Space Shuttle is ending. And SpaceX plans to take over.

Elon Musk, the millionaire founder of private space company Space Exploration Technologies Corp (SpaceX for short) said the long planned Falcon Heavy vehicle would be ready for liftoff at the end of 2012. The rocket, which he called the most powerful in the world, would be capable of taking men to the International Space Station, dropping vehicles and astronauts on the moon -- and maybe even cruising to Mars and back.

"This is a rocket of truly huge scale," Musk said at a press conference unveiling the rocket. "With Falcon Heavy, we'll be able to put well over 100,000 pounds into orbit," he said, and possibly as much as 120,000 pounds.

"That's more than a fully loaded Boeing 737 -- with passengers and fuel" and even luggage, Musk said.

The Falcon Heavy consists of a standard Falcon 9 rocket with two additional Falcon 9 first-stage rockets acting as liquid strap-on boosters. The upgraded Merlin engines that power the rocket will generate 3.8 million pounds of thrust at liftoff -- the equivalent of 15 Boeing 747s, he said.

It is intended primarily to carry satellites and other such payloads into space, though it will meet NASA's requirements for carrying humans as well.

"It can launch people if need be, and do so safely," he said.

NASA spokesman Michael J. Braukus was cautiously optimistic that the ship would help U.S. interests in space, though he declined to comment on whether Falcon Heavy would be useful for human transport.

But for cargo transport, it will clearly have a role: Musk said this version of the spacecraft would have twice the capability of the space shuttle.

The Falcon Heavy will also dramatically surpass the Delta IV Heavy's 25-ton capacity and the yet-to-be-built Atlas 5 Heavy's 32 tons. It will be assembled at California's Vanderburg Air Force Base, but Musk said it would be able to take off from Cape Canaveral as well.

Musk also claimed the Falcon Heavy would cost a third per flight than the Delta IV rocket, and sets a new world record for the cost per pound to orbit of around $1,000. A launch is estimated at $80 million, the company said, while an Atlas 5 costs as much as $100 million more.

Gates to discuss Arab upheaval with Saudi king

Gates to discuss Arab upheaval with Saudi king

Defense Secretary Robert Gates arrived in the Saudi capital 

Wednesday for talks with King Abdullah on coping with the political upheaval sweeping the Arab world, blunting Iranian efforts to exploit the unrest, and upgrading the kingdom's defenses against Iranian missiles.

In a sign of the depth of the Obama administration's concern about the political earthquake that has shaken the region, including the island of Bahrain off Saudi Arabia's Persian Gulf coast, this was Gates' third trip to the area in the past month. He has echoed Secretary of State Hillary Rodham Clinton's cautioning of authoritarian Arab governments on the risks of moving too slowly in response to peaceful protests for political freedom.

U.S. relations with the Saudi ruling family have been strained for months, dating to the uprising in Egypt and President Barack Obama's call for long-time U.S. ally Hosni Mubarak to give up his presidency. Saudi leaders saw this as the U.S. abandoning a reliable friend with close military and diplomatic ties stretching over decades — not unlike the U.S.-Saudi alliance, which has the added dimension of American dependence on Saudi oil.

Gates has acknowledged tensions in the relationship with the Saudis but insists it remains a strong partnership.

"'It's a great exaggeration to say this relationship's ruptured," Gates said last month on NBC's "Meet the Press." "We have a very strong military-to-military relationship. As you know, the Saudis just made one of the largest purchases of American weapons in their history."

He was referring to a $60 billion deal announced last fall to sell the Saudis 84 new F-15 fighter jets and 190 helicopters, as well as upgrade 70 of their existing F-15s. The deal also includes a wide array of missiles, bombs and other equipment — mostly with a perceived Iranian threat in mind. Iran, with its Shiite Muslim theocracy in charge, has long been a bitter rival of the Saudis, whose rulers and majority population are Sunni Muslim.

Limited protests in Saudi Arabia reportedly have been confined mainly to Shiites in the eastern oil-producing provinces.

A senior defense official traveling with Gates from Washington said the kingdom's internal political situation was unlikely to be broached in Gates' talks with Abdullah. The official spoke on condition of anonymity in order to discuss Gates' thinking in advance of his closed-door meeting with the king.

The official said Gates would assure Abdullah that the $60 billion arms deal is progressing on schedule, while also urging the king to buy an upgraded version of its U.S.-made Patriot air defense missiles. Gates also planned to pitch a more sophisticated U.S. defense system called the Theater High-Altitude Area Defense system, which is designed to shoot down ballistic missiles of longer range. The United Arab Emirates already has agreed to purchase that system, the official said. It is part of a broader U.S. plan to improve Gulf Arab states' defenses against Iranian missile threats.

Geoff Morrell, the Pentagon press secretary, told reporters on Gates' flight to Riyadh that "Iran will be a major focus" of Gates' talks with Abdullah — not just its missile development, but also its nuclear weapons ambitions and concerns that Iran is seeking to exploit political upheaval in the Arab world.

Strains in the U.S.-Saudi relationship deepened with the crisis in Bahrain, where a Sunni family dynasty rules a Shiite-majority population. The Saudis dread a further empowering of Shiites, following the 2003 U.S.-led overthrow of Saddam Hussein's Sunni regime and the rise to power there of a Shiite prime minister, Nouri al-Maliki.

"Saudis believe their concerns in Bahrain — containing Iran, protecting Gulf monarchies and sending a clear message to their own Shiite population — are best addressed by a hardline policy of suppressing the protests," Marina Ottaway, director of the Middle East program at the Carnegie Endowment for International Peace, wrote in an analysis Monday.

On March 14 — two days after Gates visited Bahrain's rulers — the Saudis sent more than 1,000 troops into Bahrain, at that government's request, for security assistance. Ottaway concluded from Washington's muted response that it has chosen to implicitly back the Saudis.

"Washington has seemingly accepted that for the time being the Saudis have won the battle for influence in Bahrain and concluded that mending relations with Saudi Arabia should take precedence right now," she wrote.
