NASA Buys Flights on Virgin Galactic's Private Spaceship (SPACE.com)

The space tourism company Virgin Galactic has struck a deal with NASA worth up to $4.5 million for research flights on the company's new private spaceliner SpaceShipTwo, Virgin Galactic officials announced today (Oct. 13).

Under the deal, NASA will charter up to three flights on Virgin Galactic's SpaceShipTwo, an air-launched spacecraft designed to carry eight people on trips to suborbital space.

The announcement comes just two days after Virgin Galactic announced that Mike Moses, NASA's former deputy space shuttle program chief, had joined the company's ranks as vice president of operations.

"We are excited to be working with NASA to provide the research community with this opportunity to carry out experiments in space, said George Whitesides, president and CEO of Virgin Galactic, in a statement.

"An enormous range of disciplines can benefit from access to space, but historically, such research opportunities have been rare and expensive," Whitesides added. "At Virgin Galactic, we are fully dedicated to revolutionizing access to space, both for tourist astronauts and, through programs like this, for researchers."

NASA research flights

Each suborbital spaceflight for NASA could carry up to 1,300 pounds (590 kilograms) of scientific experiments, allowing up to 600 different payloads per mission, Virgin Galactic officials said.

The company will provide a flight test engineer on every mission to help monitor and conduct experiments as necessary, they added.

In the deal, NASA committed to chartering one flight with Virgin Galactic, with options for two more. If the space agency exercises those options and charters all three flights, the contract will be worth $4.5 million, officials said.

NASA shuttle veteran comes aboard

Virgin Galactic just announced  Tuesday (Oct. 12) that it was hiring Mike Moses, NASA's former space shuttle launch integration manager, to become its vice president of operations.

In this role, Moses will oversee all operations at Spaceport America in New Mexico, the site of Virgin's commercial suborbital spaceflight program. The company is slated to dedicate its headquarters at the spaceport this coming Monday (Oct. 17).

Moses has considerable experience overseeing human spaceflight operations and most recently served as NASA's deputy space shuttle program chief, as well as the mission management team for the agency's final shuttle flights. He provided ultimate launch decision authority for the final 12 missions of the now-retired shuttle program, for example, which lofted 75 astronauts to orbit.

"Bringing Mike in to lead the team represents a significant investment in our commitment to operational safety and success as we prepare to launch commercial operations," Whitesides said.

Moses had worked as a space shuttle flight controller for 10 years before being selected as a flight director in 2005. He said he was happy to be making the leap to the private sector.

"I am extremely excited to be joining Virgin Galactic at this time, helping to forge the foundations that will enable routine commercial suborbital spaceflights," he said in a statement. "Virgin Galactic will expand the legacy of human spaceflight beyond traditional government programs into the world’s first privately funded commercial spaceline."

Virgin Galactic Pushes Private Spaceship Envelope in Test Flights (SPACE.com)

The space tourism company Virgin Galactic has put its spaceship of choice through new glide flights and re-entry technology tests in the latest round of workouts for the privately built spaceliner.

The suborbital rocket ship SpaceShipTwo has been repeatedly dropped from its mothership, called WhiteKnightTwo, at high altitude during 10 glide flights at the Mojave Air and Space Port in California.

It is the first of five SpaceShipTwo vehicles being constructed for Virgin Galactic by the Mojave-based company Scaled Composites. SpaceShipTwo is a six-passenger and two-pilot vehicle.

Those flights, Virgin Galactic officials have said, will give paying passengers a stunning view of the Earth and several minutes of weightlessness. The price per seat? A cool $200,000. Virgin Galactic's spaceliner operations are bankrolled by British entrepreneur and adventurer Sir Richard Branson, who founded the firm.

Wealth of data

The spacecraft's 10th glide flight, on May 25, featured the second evaluation of its feather re-entry system. The test "went very well," said Virgin Galactic CEO and president George Whitesides. [Video: SpaceShipTwo Passes Re-Entry System Test]

"Scaled has amassed a wealth of data and experience from the recent series of test flights which is now undergoing thorough analysis," Whitesides told SPACE.com. "Overall, the findings seem to be very positive. The team will soon enter a period of slightly less visible activity as they prepare the spaceship and carrier aircraft for the next phase of flight testing."

Whitesides added that congratulations are due to the whole team at Scaled Composites for the dedication and hard work that has made so many flights possible in such a short time.

The rocket plane made its maiden free flight on Oct. 10, 2010. Since then, it has been put through an ever-expanding set of flight objectives. 

Pushing the SpaceShipTwo envelope

At the Mojave Air and Space Port, the Scaled Composites team has been busy exploring the flight envelope of SpaceShipTwo, Whitesides added, pushing the vehicle to higher speeds and higher G-loads.

Earlier this year, SpaceShipTwo passed a critical test flight: a demonstration of its novel re-entry system, which "feathers" the vehicle's aft flight surfaces to provide stability during atmospheric re-entry.

"The feather was a major milestone," Whitesides said, with the glide flights exploring the aerodynamic envelope and seeing how plane reacts to pilot.

SpaceShipTwo’s ability to feather its tail section is a unique control feature.

On a suborbital trek, SpaceShipTwo would boost itself upwards out of Earth's atmosphere to about 69 miles (110 kilometers), the vehicle’s maximum altitude.

In re-entry mode, the tail structure of the craft will be rotated upward to about 65 degrees. In this feathered configuration, automatic control of attitude is achieved with the fuselage parallel to the horizon. This creates very high drag as the spacecraft descends through the upper regions of the atmosphere.

At around 70,000 feet (21,336 meters), SpaceShipTwo's feather would lower to its original configuration. The unpowered spaceship then would glide to a spaceport runway and touchdown.

The two feathered tests to date - though not done under all conditions that would be encountered during a full-blown plunge from space - matched predictions, Whitesides said.

Next big milestone

Regarding the mood of those working on SpaceShipTwo, "everybody wants to move forward as quickly as possible … while still being safe about it," Whitesides said. "There's a lot of satisfaction that they’ve built something that's basically a stable airframe. They are feeling pretty good so far."

Whitesides said pilot proficiency is central to the SpaceShipTwo’s test card. "They’ve got a pretty deep bench of fantastic pilots," he said.

Clearly, the integration of the hybrid motor with SpaceShipTwo is the next big milestone. That powerhouse engine is being crafted by Sierra Nevada Corporation. Short bursts to ever-long burns of the motor during flight are being planned. The first in-flight firing is still to be determined.

"Realistically, probably around end of the year or early next year. We'll have to see how things go," Whitesides said.

'Fascinating times'

Mark Sirangelo, head of Sierra Nevada Space Systems, the prime contractor for the SpaceShipTwo motors, told SPACE.com that progress is ongoing regarding development of the hybrid motor propulsion for the SpaceShipTwo program. [Vote Now! The Best Spaceships of All Time]

"Recently we conducted a firing of the motor which extended the burn duration by 30 percent and validated several of the important hardware systems," Sirangelo said. "We are preparing to shortly conduct another firing of the enhanced motor which will extend the burn duration and incorporate several additional important advances in the design.

This firing is expected to lead to final design of the motors for flight testing," he explained.

"Fascinating times," said Stuart Witt, general manager of the Mojave Air and Space Port. While more- aggressive testing of SpaceShipTwo is on tap, other space firms on the spaceport property ? including Masten Space Systems, XCOR Aerospace and Firestar Technologies ? continue to make progress, he added.

"We are now operating seven days a week … continue to add well-paying jobs and work to capture additional projects seeking a risk-friendly location," Witt told SPACE.com. "We see nothing but exciting times ahead."
