Privately-funded Space Exploration Technologies, the company operated by Internet entrepreneur Elon Musk, received final clearance from the US Air Force on Thursday for its debut rocket launch from Florida.
The company known as SpaceX was set to launch its Falcon 9 rocket between 11am and 3pm yesterday from its newly refurbished launch pad at Cape Canaveral Air Force Station, just south of the Kennedy Space Center.
Musk, who moonlights as chairman and chief executive of electric car manufacturer Tesla Motors, put the odds of a successful flight at around 75 percent.
“I think we’re probably three-quarters likely to succeed. I hope that fate favors us tomorrow,” Musk said on a conference call with reporters.
The company has flown smaller rockets from the Kwajalein Atoll’s Omelek Island in the Pacific with mixed success, which Musk says is typical of any new technical system, particularly rocketry. The Falcon 9’s goal is to reach orbit and typically, about half of the first flights of new rockets end short of reaching that mark.
The 55m-high, liquid oxygen and kerosene-fueled booster will carry a mock-up of a SpaceX capsule known as the Dragon, which NASA plans to use to fly cargo — and perhaps astronauts — to the International Space Station (ISS).
NASA is retiring its shuttle fleet after two more flights this year to complete assembly of the ISS, a US$100 billion project of 16 nations. No replacement is planned under the NASA budget proposal for the year beginning Oct. 1, which is pending before US Congress.
While NASA shifts its focus to research and technology development, the Obama administration is looking to private firms like SpaceX to pick up NASA’s share of the ISS resupply business. Russia, Europe and Japan fly cargo ships to the ISS, while Russia operates the only space taxi service for crewmembers. China, which has also flown people in orbit, is not part of the ISS partnership.
Yesterday’s planned flight is part of SpaceX’s US$400 million development effort to design and fly discount rockets for governments, companies and research institutes. Of that, US$100 million came from Musk, co-owner of the PayPal electronic payment system that eBay Inc acquired in 2002 for US$1.5 billion.
SpaceX is selling its Falcon 9 rockets, which can carry 12 tonnes to an orbit about 360km above Earth, for about US$50 million — less than half what is typically charged for rides on similar US rockets.
“If the vehicle lifts off the pad, no matter what the outcome is, we’re going to learn something that’s going to make the second flight more likely and the third flight and the fourth flight,” added Ken Bowersox, a SpaceX vice president and former NASA astronaut.
The firm plans to fly up to three Falcon 9/Dragon test missions for NASA, then begin delivering cargo to the ISS under a US$1.6 billion contract next year. NASA also has a US$1.9 billion ISS resupply contract with Orbital Sciences Corp, which plans to debut its Taurus 2 rocket next year.
Chinese authorities have marshalled extraordinary resources to monitor a herd of traveling elephants and to keep it away from residential areas. Media reports quoted the Yunnan Forest Fire Brigade as saying that a team of eight people have been tracking the elephants, around the clock, on the ground and by drone. In the latest update, authorities said that the herd of wild Asian elephants had been tracked to a forest just outside a village in Xiyang Township, in Yunnan Province, about 90km southwest of the city of Kunming, heading back in the direction they came from. Drone images showed the elephants lying down
Tall, thin and brightly colored, Hanoi’s “tube houses” dominate the city’s streets as 9 million people compete for space in Vietnam’s bustling capital. Although Vietnam saw a number of villas and garden houses built during the French colonial period, Hanoi has few of these grand residential homes. Instead, tree-lined streets are packed with dwellings that are barely 4m wide, but are three times that in depth. Typically, a tube house might be home to a family of four, but two or three generations of relatives sometimes have to jostle for space. The first tube houses — known as nha ong in Vietnamese — are
The head of the Philippine military on Monday visited a coral-fringed island his country occupies in the South China Sea, a move that could stoke already heightened tensions between Manila and Beijing in disputed waters claimed by both countries. During the visit, Philippine Armed Forces Lieutenant General Cirilito Sobejana commended service members for the role they played in protecting the island’s residents and “guarding the country’s territories” in the strategic waterway. The visit comes after diplomatic protests made by the Philippines in the past few months over what it says is the illegal presence of hundreds of “Chinese maritime militia” vessels inside
Maori might have been the first to discover Antarctica, with connections to the icy continent and its surrounding oceans stretching back to the seventh century, researchers say. A new paper by University of Otago combines literature and oral histories, and concludes that Maori were likely the first people to explore Antarctica’s surrounding waters and possibly the continent in the distance. They write that Maori and Polynesian journeys to the deep south have been occurring for a long time, perhaps as far back as the 7th century, and are recorded in a variety of oral traditions. The oral histories of Maori groups Ngti Rrua
