SpaceX launches upgraded Falcon 9 rocket

09/29/2013 12:37 PM 

By WILLIAM HARWOOD
CBS News

In a dramatic California test flight, SpaceX launched an upgraded, more powerful version of its Falcon 9 rocket Sunday -- a booster the company hopes will someday carry astronauts to the space station -- to place a modest Canadian science satellite into orbit along with five smaller research payloads.

The Falcon 9 version 1.1 features more powerful engines, a longer first stage to accommodate larger propellant tanks, a new payload fairing and a triply redundant flight computer system, improvements intended to boost the rocket's payload capability while improving safety and reliability.

The 224-foot-tall rocket also featured simplified stage attachment mechanisms, a new circular engine arrangement for the first stage and a beefed up first stage heat shield. The company eventually hopes to recover spent stages for refurbishment and reuse.

Given the multiple upgrades involved, Elon Musk, SpaceX's CEO and chief designer, said he considered the launching a test flight. Canada's 1,100-pound Cassiope space weather satellite, provided by MacDonald, Dettwiler and Associates, the Canadian Space Agency and the University of Calgary, reportedly got the ride for about $10 million.

"We don't consider this to be an operational launch," Musk told Spaceflight Now in a pre-launch interview. "It's a demo or a beta launch. Cassiope understands that. They got a pretty significant discount since this is a new Falcon 9."

The towering rocket's nine upgraded Merlin 1D first-stage engines ignited at 12 p.m. EDT, throttled up to a combined 1.3 million pounds of liftoff thrust and quicky pushed the slender booster away from Space Launch Complex 4-East at Vandenberg Air Force Base northwest of Los Angeles.

Once used by Air Force heavy-lift Titan 4 rockets, the launch pad was extensively modified by SpaceX in a $100 million makeover, providing a launch site for payloads that must be delivered into polar orbits. SpaceX also operates a launch complex at the Cape Canaveral Air Force Station in Florida for payloads that require more equatorial orbits.

The Falcon 9 is designed to achieve orbit even if two of the first-stage engines fail in flight, but all nine Merlin 1Ds appeared to fire normally during the booster's climb away on a southerly trajectory over the Pacific Ocean.

The first stage burned out and fell away about two minutes and 50 seconds after liftoff. The rocket's single-engine second stage then continue the drive to space, burning another six minutes before shutting down around eight minutes and 54 seconds after launch.

A crowd of SpaceX employees gathered at the company's Hawthorne, Calif., factory burst into cheers and applause.

"It was an amazing flight," John Insprucker, Falcon 9 product manager, said in a company webcast. "So far, and there's tons of data coming back, it looks like it was a picture-perfect flight, everything was looking good, right down the middle of the track."

The flight plan called for the Cassiope space weather satellite to be released about five minutes later into a planned orbit with a high point of around 930 miles and a low point of about 185 miles.

Three small "cubesats" making up the Polar Orbiting Passive Atmospheric Calibration Spheres, or POPACS, then were to be ejected from a dispenser a few minutes later. The mission is sponsored by Utah State University, Planetary Systems Corp. and Drexel University. Confirmation of the satellite releases was expected later in the day.

The rocket's other two satellites were expected to be deployed a few minutes after that. The 51-pound CUsat navigation research satellite was built by students at Cornell University. A 110-pound atmospheric probe known as DANDE, for Drag and Atmospheric Neutral Density Explorer, was provided by the University of Colorado at Boulder.

SpaceX developed the Falcon 9 as a purely commercial venture to boost civilian and military satellites into space along with company-designed Dragon cargo ships built to carry supplies and equipment to and from the International Space Station.

SpaceX holds a $1.6 billion contract with NASA for at least 12 station resupply missions to deliver some 44,000 pounds of cargo and supplies.

Prior to Sunday's flight, SpaceX had successfully launched five Falcon 9s using first-stage Merlin 1C engines generating just under 900,000 pounds of sea-level thrust. Two Dragon test flights and two operational space station resupply missions have been launched to date.

SpaceX also is participating in a NASA competition, along with Boeing and Sierra Nevada, to develop a commercial manned spacecraft to ferry crews to and from the space station.

Musk hopes to use the Falcon 9 v1.1 and an upgraded manned version of the Dragon cargo ship to provide low-cost transportation to low-Earth orbit. The rocket also can be used for heavier commercial and military satellites.

The v1.1 modifications start at the base of the rocket where the new engines are arranged in a circular "octaweb" pattern with eight powerplants surrounding a central engine. The earlier version had the engines arranged in a square 3-by-3 arrangement, requiring aerodynamic panels around the base of the rocket.

In the new version, protective panels were installed between the engines to prevent a malfunctioning engine from damaging another. The first stage also features longer propellant tanks a heat shield.

For the initial test flight, engineers planned to restart the first stage engines as it fell back to Earth to slow it down before plunging back into the thick lower atmosphere. The stage was not designed to be recovered, but Musk plans to collect data on every flight to perfect an eventual recovery system.

"I give pretty low odds of this recovery working on this flight," Musk told Spaceflight Now. "The point of this mission is demonstrating the ascent of the crewed version of the Falcon 9."

The v1.1 version of the Falcon 9 is the company's first to feature a payload fairing that can encapsulate large satellites. The fairing separated and fell away as planned just after the second stage ignited.

Another major upgrade was a triply redundant flight computer running new software. Musk said the new computer system was extremely robust.

"You could put a bullet hole in any one of the avionics boxes and it would just keep flying," Musk told Spaceflight Now.

Other improvements include a simpler, more reliable mechanisms to connect the rocket's stages, using three connectors in place of nine.

The new Merlin 1D engines feature more efficient fuel injectors and weigh in at under 1,000 pounds each. The company said improvements in robotic manufacturing techniques, along with fewer parts make the engines easier to build and improve reliability.

MOSCOW, September 29 (RIA Novosti) – Russia will launch the first Proton-M unmanned carrier rocket in three months on Monday, bringing into orbit a European telecom satellite, the country's space agency said Sunday.

The rocket carrying the Astra 2E satellite will blast off the Baikonur space port in Kazakhstan at 1:38 a.m. Moscow time (9:38 p.m. Sunday UTC), a spokesman for Roscosmos told RIA Novosti.

The previous Proton-M launch on July 2 ended in a crash seconds after start. The incident, which led to the loss of three navigation satellites for Glonass, Russia's answer to GPS, was blamed on sensors installed upside down and hammered in to fit by careless manufacturers.

The incident boosted Russian government's plans to revamp the country's space industry, which saw a string of failed launches in recent years. A draft of the reform, which proposes to consolidate the 100-plus state-run space industry enterprises into one corporation or half a dozen holdings, was recently filed with the Cabinet and is now under review.

The six-ton Astra 2E, manufactured in France for Luxembourg-based SES S.A. satellite operator, will provide television and radio broadcasts, as well as mobile and internet communications for users in Europa, Africa and the Middle East.

Less than three months after the spectacular—though catastrophic—loss of a Proton-M booster in July, International Launch Services (ILS) is primed to return the venerable vehicle to flight. Liftoff of the three-stage Proton and its troubled Briz-M upper stage from Pad 39 at Site 200 at the Baikonur Cosmodrome in Kazakhstan is scheduled for 2:38 a.m. local time Monday (4:38 p.m. EDT Sunday), carrying the Astra 2E communications satellite into 22,300-mile geosynchronous orbit. The 174-foot-tall Proton was rolled horizontally out to the launch pad on Thursday, 26 September and raised into a vertical orientation, with propellant loading operations slated for early Sunday.

This launch is long-awaited, coming on the heels of the last Proton mission, which failed seconds after launch on 2 July. As highlighted in dramatic YouTube imagery, the 1.5-million-pound Proton started pitching wildly to the left and right along its vertical axis shortly after leaving the pad. Efforts to bring these unwanted motions under control by the guidance system were unsuccessful, and the vehicle entered an unmanageable pitchover and hit the ground in a fireball at T+30 seconds. Last month, the Russian government formed the United Rocket and Space Corporation to consolidate the space sector, with Deputy Prime Minister Dmitri Rogozin announcing that it was "so troubled that it needs state supervision to overcome its problems." The corporation is expected to gain a controlling interest in the Energia rocket engine manufacturer, in which the Russian government already held a 38-percent interest level.

On 13 August, the ILS Failure Review Oversight Board (FROB) and Russia's State Inter-agency Commission revealed that three angular velocity sensors for yaw control of the Proton's first stage had been installed incorrectly and formed the root cause of the accident. Moreover, it was suggested that an umbilical separated prematurely, with the vehicle leaving the pad a few tenths of a second early, before the engines had reached full thrust. As it pitched over in its final seconds, the upper stages of the rocket and the payload—a trio of GLONASS navigation satellites—were torn away from the burning Proton and destroyed. "We very much appreciate the time, effort and participation of our customers, the insurance underwriters and technical experts in the FROB process," said John Palmé, ILS Vice President of Programs and Operations. "They worked tirelessly with us to ensure that the review was conducted thoroughly. As we work towards the return to flight of the Proton vehicle, we thank all of our customers for their continued support." The accident marked the first failure by a Proton during first-stage flight in over 30 years.

At the time of the accident, efforts had entered high gear for the launch of Astra 2E aboard the very next Proton. The cube-shaped spacecraft—built by the Luxembourg-based SES global satellite provider—arrived at Baikonur in mid-June, followed by the Proton's restartable Briz-M upper stage a few days later. Liftoff was scheduled for the night of 20/21 July, but was put on indefinite hold in the wake of the accident. Eventually, ILS announced that it was tracking a new launch date in mid-September, but technical troubles rendered this target unachievable. Detoxification of the accident zone and reports from ILS relating to "an out-of-tolerance reading in the first stage of the vehicle" conspired to delay the launch by two weeks. On 22 September, a new launch date and time of 2:38 a.m. local time Monday, 30 September (4:38 p.m. EDT Sunday the 29th) was scheduled. Rollout of the Proton-M and Astra 2E payload to Pad 39 at Site 200 occurred on 26 September.

Flown 70 times since April 2001, with six failures and two partial failures, the Proton-M comprises three main stages and on this launch will also utilize the restartable Briz-M upper stage. This allows it to inject payloads weighing up to 14,800 pounds into geosynchronous transfer orbit and up to 7,700 pounds directly into a 22,300-mile geosychronous orbit. The vehicle is built by the Khrunichev Research and State Production Centre, and its heritage extends back to the mid-1960s, with a launch history of almost 400 flights and one of the most reliable track records in the world. All of its stages, including the Briz-M, utilize nitrogen tetroxide and unsymmetrical dimethyl hydrazine propellants. Its first stage consists of a central oxidizer tank, surrounded by six outboard fuel tanks, each fed by an RD-276 engine, and these will provide the initial impetus to boost Astra 2E toward orbit.

Fueling of the main three stages is expected to begin about nine hours ahead of liftoff. Ignition of the six RD-276 engines will commence at T-2 seconds, ramping up to 100 percent to produce 2.3 million pounds of thrust at liftoff. A little over a minute into the ascent, the Proton will encounter the period of maximum aerodynamic turbulence (known as "Max Q") on its flight surfaces, with the separation of the first stage scheduled at the two-minute point. The second stage will then pick up the baton, with its four engines generating a combined 540,000 pounds of impulse for a little over 3.5 minutes. Shortly after the second stage separates from the vehicle, the Payload Fairing (PLF) will be jettisoned and the single-engine third stage will add an extra 138,000 pounds of thrust for the next four minutes of flight. Shutdown of the third stage is expected about 10 minutes after launch, by which time the vehicle will have been placed onto a suborbital trajectory.

The turn will then come for the single-engine Briz-M upper stage, which has exhibited a mixture of success and failure since its maiden voyage, back in May 2000. In August 2012, a premature shutdown of the Briz-M left Indonesia's Telkom-3 and Russia's Ekspress-MD2 satellites in useless orbits, and in December 2012 another launch glitch impacted the Yamal-402 satellite. Last March, a Proton-M/Briz-M successfully injected Mexico's Satmex-8 communications satellite into orbit. Capable of restarting up to eight times in flight, the Briz-M has a battery-powered lifetime of 24 hours and is scheduled to execute five "burns" to insert Astra 2E into orbit.

Its first burn will last 4.5 minutes and is due to commence about 11 minutes into the mission, after which the Briz-M/Astra 2E combo will enter a circular "parking orbit" and coast for almost an hour, preparatory to the second burn. This will be a much longer firing of almost 18 minutes, followed by a two-hour period of coasting, then a third burn of 11.5 minutes and a fourth of about six minutes in duration. After the fourth burn, the combo will coast for about five hours, ahead of the final scheduled Briz-M firing at T+8 hours and 53 minutes. This six-minute burn will position Astra 2E into geosynchronous transfer orbit, and at T+9 hours and 12 minutes the 13,200-pound satellite will separate from the upper stage.

Owned and operated by the Luxembourg-based SES global satellite provider, Astra 2E will be positioend at 28.2 degrees East in geosynchronous orbit. Equipped with three Ku-band downlink beams covering Europe and the Middle East, it will provide digital television and satellite broadband services for Europe and the Middle East. It forms the second of three "second-generation" satellites assigned to the 28.2 degrees East orbital position. Astra 2F was launched by Europe's Ariane 5 in September 2012, and Astra 2G will fly in spring 2014. Upon arrival in its orbital slot and after initial checkout, Astra 2E will take over the channels currently broadcast by the Astra 1N satellite. Together with Astra 2F, the new satellite will deliver programs to 13 million satellite homes and 3 million cable homes. The satellite weighs 13,200 pounds and is expected to operate for 15 years.

2 years later, NASA workers still mourn end of shuttle

By Mark K. Matthews, Washington Bureau

2:19 p.m. EDT, September 28, 2013

WASHINGTON — Few engineers at Kennedy Space Center invested as much in the space-shuttle program as Darrell Gheen, who worked all 135 flights from 1981 to 2011.

Though the Cal Ripken-esque achievement earned him a special patch, the streak didn't do much for the 53-year-old's job prospects once the program ended with the final mission of Atlantis in July 2011.

Like thousands of other ex-shuttle workers, Gheen — who spent the final 13 years of his shuttle career as a flight-controls engineer — was forced to find work wherever he could. It's a situation that, for many, remains stubbornly true two years later.

In Gheen's case, the end result isn't all bad. After working for months at a brother's boat-building company, he landed a job last year as a launchpad manager at a spaceport in Virginia at a higher salary, a rarity among ex-shuttle workers. But even that has its drawbacks, as others in his family stayed behind in part because they can't sell their Titusville house.

"It's been months since I've been home," Gheen said.

 

Up and down the Space Coast, a similar story is playing out for thousands of families. Though the initial shock of the shuttle's retirement has long faded, the grind to find meaningful work — and a comparable paycheck — remains a constant pursuit.

Some, like Gheen, have left Florida so they could keep working in the aerospace business. Others have stuck close to home, often switching fields to find new jobs — from teaching to lawn maintenance to asphalt resurfacing — at a reduced salary. One lucky group has managed to do both: stay local and in the aerospace sector.

But that's not the majority. At least not yet. And maybe not ever.

Precise figures on what's happened to the shuttle work force are unavailable, but this much is known: From 2008 till now, the number of KSC workers was roughly halved to its current figure of about 7,900.

Most of the roughly 7,000 who lost their jobs were not NASA employees but outside contractors, doing jobs such as refurbishing the tiles that protected the shuttle from harm. It was well-paid work. According to one 2008 study, the average shuttle contractor then earned about $77,600 a year — nearly twice the mean salary of Brevard County.

But when the shuttle program ended without an immediate NASA successor, these workers were left with few options. So they scattered.

"It's been quite a roller coaster," said Gregory Cecil, a former tile technician now working as a middle-school science teacher in St. Petersburg.

Cecil took a buyout in 2009 but then spent more than two years trying to find a full-time job.

"I was really, really starting to fear I was never going to work again," he said.

Finally, he decided to switch fields and start teaching. His salary dropped from $50,000 to $30,000.

"I like it. I like where I am now," said Cecil, 49. "But I would rather be working on spaceships."

The current state of the U.S. space industry restricts that career path.

Despite the recent emergence of new players such as SpaceX of California, no one is expecting the industry to hire anything close to the standing armies once needed to put the shuttle into orbit.

And NASA is still years from launching its next human-rated rocket, the Space Launch System. NASA wants a first flight in 2017, but budget problems could push that date back. Any delay would be especially painful for KSC, as its primary role for decades has been preparing NASA spacecraft for launch.

But Brevard business leaders are optimistic. Though not ideal, local job figures have been far from devastating. As of July, the unemployment rate in Brevard County was 7.8 percent — within arm's reach of the 7.1 percent state average that month, according to records from the Bureau of Labor Statistics.

That compares with 11.2 percent in August 2011, the month after Atlantis touched down.

"Given the circumstances, things could have been much worse," said Lynda Weatherman, president and CEO of the Economic Development Commission of Florida's Space Coast.

She credited several factors, including an aggressive effort by local and state leaders to lure new businesses to the area. These have resulted in an estimated 5,000 "announced" jobs in Brevard County, she said — though some won't be hiring for a couple of years.

Weatherman didn't have a breakdown of how many positions are filled. But she noted that the 5,000 figure includes 1,000 jobs that Northrop Grumman expects to add during the next four years at an aircraft-design center in Melbourne.

"I challenge any other community in this nation to respond how we have," Weatherman said.

Yet several ex-shuttle workers say that they've lost more than a paycheck.

"No one was expecting the same wages — or the prestige of working on a premier space program," said Terry White, who worked as a shuttle contractor for 33 years before losing his job the day after Atlantis landed.

Though he no longer works for a salary, White, 64, volunteers with NASA as a tour guide for special guests visiting KSC. It helps him stay connected to KSC family, a bond that many of his co-workers have said is missing in their current jobs.

"It's not the same camaraderie," he said.

Focus on Mars
NASA is a lead or partner agency in three missions currently orbiting Mars and two roving the surface.
Overhead are Mars Odyssey, Europe's Mars Express, and the Mars Reconnaissance Orbiter, launched in 2001, 2003 and 2005, respectively.
On the surface are NASA's two Mars Exploration Rovers, nicknamed Spirit and Opportunity, which landed in 2004 (contact with Spirit has been lost), and the Mars Science Laboratory, dubbed Curiosity, which landed in 2012.

CAPE CANAVERAL — Bathed in orange light and with two black solar wings outstretched, NASA's Maven spacecraft on Friday looked as if it might already be orbiting Mars.

That destination is still a year away, but the $671 million mission is approaching its Nov. 18 blastoff from Cape Canaveral Air Force Station atop an Atlas V rocket.

"We've been working on this mission for years, and we're close now, real close, and we're going to Mars, so it's really pretty cool to be at this point," said Dave Mitchell, project manager from the Goddard Space Flight Center in Greenbelt, Md.

During a media day at Kennedy Space Center, where pre-launch tests are in progress, managers sidestepped questions about how a government shutdown might affect launch plans, saying they would do everything possible to stay on track.

Their schedule still has nine days of margin should technical or other problems arise, and a 20-day launch window can be extended deeper into December if necessary.

Miss that, and the mission would be grounded for two years before the right planetary alignment returned.

Unlike previous missions that have orbited, landed or roved on Mars, Maven is interested less in the planet's surface than its upper atmosphere.

Eight instruments will study the thin atmosphere and the sun's influence upon it to understand its history.

How and when did a once warm and wet planet become so cold and dry?

"It's going to tell us why the atmosphere changed over time," said Bruce Janofsky, the mission's lead scientist from the University of Colorado's Laboratory for Atmospheric and Space Physics in Boulder. "We think that the surface was conducive to supporting life 4 billion years ago, and not today, and we're trying to learn why."

Water and carbon dioxide could have been trapped in minerals and ice below the surface, Janofsky said, but a bigger driver may have been the loss of gasses through the top of the atmosphere.

Over at least a year, Maven – an acronym for Mars Atmosphere and Volatile Evolution Mission – will collect data during five "deep dips" through the upper atmosphere.

"We're just brushing the edge of the atmosphere," said Guy Beutelschies, project manager for Lockheed Martin Corp., which built the spacecraft and a predecessor on which it is based, the Mars Reconnaissance Orbiter.

To help control its flight, Maven's solar arrays are canted slightly like a gull's wings.

On Friday, those arrays stretched 37.5 feet from tip to tip, or about the length of a school bus, inside KSC's Payload Hazardous Servicing Facility, where they were recently deployed for tests.

A large, dish-shaped antenna for transmitting data to Earth was sheathed in silver insulation.

Before entering the ultra-clean high-bay, mission and media personnel donned light blue bunny suits with masks, booties and gloves taped to their wrists, then they were "showered" with jets of air.

The precautions are taken to prevent spacecraft contamination or the possibility microbes could be transported to Mars.

Maven will be fueled in late October, enclosed in a protective fairing and moved to the launch pad in early November for placement atop United Launch Alliance's 19-story Atlas V rocket.

"I've got to say, these are exciting times," Mitchell said.
