SpaceX拟将COTS Demo 2和Demo 3合并为一次任务,NASA则希望根据COTS Demo 1的试验结果再做决定。

SpaceX Seeks To Drop a Dragon Flight from COTS Plan

By Amy Klamper

WASHINGTON — Buoyed by the successful debut of its Falcon 9 rocket June 4, Space Exploration Technologies (SpaceX) Corp. is hoping to persuade NASA to waive one of three planned test flights designed to prove its reusable Dragon capsule can ferry cargo to the international space station.

SpaceX is making its case for condensing the demonstration phase even as it prepares to launch its first full-fledged Dragon spacecraft late this summer.

Under its $278 million Commercial Orbital Transportation Services (COTS) agreement with NASA, the Hawthorne, Calif.-based company is on the hook to complete three increasingly sophisticated demonstration flights of Falcon 9 and Dragon before beginning regular supply runs to the space station next year.

Although the Falcon 9 delivered a model of the Dragon capsule into orbit June 4, the flight was not meant to count as a COTS demonstration.

SpaceX founder and Chief Executive Elon Musk says it makes sense at this point to combine the last two COTS flights into a single demonstration.

“The goal of the program was the demonstration of cargo transport to and from the station. The goal was not three flights,” Musk told Space News in a June 10 interview. “That is a means to an end. But if there is a better means to that end, it makes more sense to go with the better means to that end.”

Under Musk’s proposal, SpaceX’s second COTS flight — a five-day mission during which Dragon would approach within 10 kilometers of the space station and exercise its radio cross-link to demonstrate the ability of the station’s crew to receive telemetry from the capsule and send commands — would be combined with the third and final COTS demo, in which Dragon is supposed to berth to the station for the first time.

Musk says if the modified second flight is unsuccessful, the third demo flight could serve as a backup. But if his plan works, the combined demo would clear the way for SpaceX to begin delivering cargo to the orbiting outpost under a $1.6 billion Commercial Resupply Services contract it signed with NASA in December 2008.

Regardless, Musk says that if he is able to achieve the primary objective of the COTS program, he expects NASA to pay SpaceX for all three flights — valued at $10 million each under an amended COTS agreement the company renegotiated with NASA in early 2008 — regardless of the number of demos flown.

“If we achieve the goal of the program, we should get the full amount of the program,” Musk said, adding that negotiations with NASA are under way.

Valin Thorn, deputy manager of NASA’s Commercial Crew and Cargo Program, said that any decision to eliminate a demo flight will have to wait until SpaceX flies its first COTS demo later this summer.

“It looks like we’ll have our first COTS demo in late August, and depending on how well that goes, we would take into consideration and look at how that might change the rest of the demonstration program,” Thorn said June 11.

Musk said SpaceX continues to review data gathered during Falcon 9’s maiden flight, and that he expects to complete a preliminary report by the end of June.

“But I’m not sure we’re going to release that,” he said. “There’s not much point in releasing something that’s just fodder for our competitors who will stop at nothing to kill us.”

Although the flight went well, it was not flawless.

Musk said he was surprised by a pronounced roll that occurred following startup of the rocket’s upper stage.

“We didn’t expect the roll, but it didn’t affect the insertion vector,” Musk said. “If that had occurred on a COTS flight it wouldn’t have made any difference.”

The loss of the Falcon 9’s spent first stage, which broke up on atmospheric re-entry, was another disappointment for Musk, who had hoped to recover the spent core.

“It was never one of the main mission objectives. It really would have been nice to have, but at the same time no one has ever recovered a liquid booster stage before so it would have been history,” he said. “Unfortunately, there was a microwave tracking radar that was supposed to be tracking the first stage, and instead it locked on the second stage after stage separation. So unfortunately we don’t have much information about why it broke up.”

The first stage was equipped with parachutes to enable an intact water recovery.

Musk said recovering the Falcon 9’s main stage remains a goal, but cautioned it could take “five or six flights before we could recover a stage, maybe more.”

With Falcon 9’s maiden flight behind him, Musk said the company is undergoing the readiness review for the first COTS flight, a five-hour mission meant to show Dragon can complete multiple orbits, transmit telemetry, receive commands, maneuver, re-enter the atmosphere and make a safe water landing and recovery.

In May the company acknowledged a delay in the second COTS flight, previously scheduled for November but now slated for April 2011 at the earliest. Musk attributes the slip in schedule to the extra time needed to design the second Dragon spacecraft to berth with the space station, including the addition of a grapple fixture and the avionics and software that comprise the capsule’s proximity operations and berthing system.

However, Alan Lindenmoyer, manager of NASA’s Commercial Crew and Cargo Program, said in late May that a variety of factors contributed to the five-month delay, including the time, attention and resources the company was putting into ensuring the success of Falcon 9’s maiden flight.

“Putting that much attention on the first flight has used up resources that contribute to delays in the subsequent mission,” he told Space News May 27.

Musk says SpaceX has spent roughly $500 million to date developing Dragon and the Falcon family of rockets, establishing launch facilities on the Kwajalein Atoll and at the Cape, and building a rocket test facility in McGregor, Texas.

He said NASA has funded more than half of the company’s total expenditures since 2006, with $248 million coming from COTS and $101 million from progress payments on the Commercial Resupply Services contract.

下次暂定今年8月,是COTS demo 1飞行,只飞数小时就下来,主要全程验证Dragon。

Demo 2和Demo 3本来一次是交汇,一次是对接,计划都是在明年。SpaceX现在希望能将它们合二为一,一次实现对接,这样可以省去一次飞行的费用,并加快进度。不过Demo 3飞行仍然会准备好,不过是作为Demo 2的备份。

十大“飞船”中sundancer根本就不是飞船,天鹅座还没载人计划,Armadillo的东东则差得更远。这三个放进去不恰当。剩下7个中,轨道3个(龙、追梦者、EA/RRV),亚轨道4个。个人观点,按可行性排行,依次是太空船二号、龙、EA/RRV、追梦者、山猫、New Shepard、银镖。后面5个还很渺茫。

其实还漏了:波音/Bigelow合作的Orion Lite、欧洲EADS的亚轨道飞船、俄罗斯的Cosmopolis XXI等。这些至少比那个银镖靠谱点。

SpaceX获得Iridium-Next发射合同,价值4.92亿美元,数量不明的卫星将由Falcon 9从VFAB的SLC-4发射


Contract for Launch of Iridium NEXT Satellite Constellation Represents a New Benchmark in Value for Commercial Launch Services

MCLEAN, Va. and HAWTHORNE, Calif. – June 16, 2010 – Iridium Communications Inc. (Nasdaq:IRDM) and Space Exploration Technologies (SpaceX) are pleased to announce that the Falcon 9 will be a major provider of launch services for Iridium NEXT, Iridium’s next-generation satellite constellation. The $492 million contract, while being the largest single commercial launch deal ever signed, nonetheless represents a new benchmark in cost-effective satellite delivery to space.

Iridium operates the world’s largest commercial satellite constellation, and is the only communications company to offer mobile voice and data services across the entire globe. SpaceX’s Falcon 9 launch vehicle will carry multiple Iridium NEXT satellites per vehicle, inserting the satellites into a low-earth orbit (LEO) as Iridium replaces its current satellite constellation. The Iridium NEXT satellites are set to launch from Vandenberg Air Force Base (VAFB) in California between 2015 and 2017.

The contract stipulates that SpaceX will provide launch services to Iridium over a two-year period starting in early 2015. Iridium is also in discussions with, and expects to contract with, at least one additional launch services provider. Launch services are included in the total estimated cost of $2.9 billion for Iridium NEXT.

“This is the third major building block on the road to Iridium NEXT,” said Matt Desch, CEO of Iridium. “Two weeks ago, we announced our fixed-price contract with Thales Alenia Space. We also announced our Coface-backed financing plan, and today I am pleased to announce our partnership with SpaceX for extremely cost-effective launch services.”

Added Desch, “We are proud to be partnered with SpaceX, and want to congratulate Elon Musk and the entire SpaceX team on its successful inaugural Falcon 9 launch. Hands down, SpaceX offered us the best value coupled with an unwavering commitment to flawless performance and reliability. SpaceX has combined the best of aerospace and commercial best practices to design reliable and cost-effective access to space, and Iridium will be the beneficiary of that effort.”

Desch further commented, “SpaceX also offered dedicated Iridium NEXT launch slots within its manifest, which currently has 24 Falcon 9 flights scheduled ahead of us, including those for commercial and government customers, during the coming five years. Clearly, SpaceX has established itself as a significant player in the launch industry, and we have great confidence that SpaceX will build on its recent success and continue to cement an impressive track record of successful space flight in advance of our mission.”

The June 4 inaugural launch of SpaceX’s Falcon 9 achieved 100 percent of its mission objectives, culminating in a near b ull’s-eye insertion to its targeted 250km circular orbit. SpaceX has been working with Iridium and Thales Alenia Space, the prime contractor for Iridium NEXT, to ensure compatibility between the satellite design, the Falcon 9 vehicle and the Iridium NEXT program schedule. This full coordination positions Iridium, SpaceX and Thales Alenia Space for a successful multi-year process of designing, building and launching Iridium NEXT.

“Iridium NEXT is now our largest commercial satellite launch customer and we are excited to play such an integral part in the most significant commercial space program underway today,” said Elon Musk, CEO, SpaceX. “We are impressed by Iridium’s comprehensive approach and diligence in its planning as the company prepares for the design, build and launch of Iridium NEXT. SpaceX greatly appreciates Iridium’s efficient approach to satellite production – an approach we share when it comes to our launch vehicles. As the next generation of the world’s only global satellite constellation that reliably covers 100 percent of the Earth’s surface, the implementation of the Iridium NEXT satellites will mark a significant achievement in mobile satellite communications, and SpaceX is looking forward to making it happen.”  

The SpaceX Falcon 9 is a medium-to-heavy lift, two-stage launch vehicle capable of lifting approximately 11 tons to LEO. Designed to the highest levels of reliability and performance, NASA selected Falcon 9, along with the SpaceX Dragon spacecraft, to resupply the International Space Station starting in 2011. This $1.6 billion contract represents 12 flights to and from the International Space Station. Further validating the reliability and robustness of commercial launch, President Obama recently decided to turn over astronaut transport to the U.S. commercial sector, specifically mentioning the example of Falcon 9 in his historic speech at Cape Canaveral. The U.S. government’s confidence in SpaceX provided further validation for Iridium’s decision.

不过建立Iridium NEXT 的全部费用(包括卫星、发射、地面站和全寿命运行费用)要29亿美元,NSF上有不少人怀疑铱星能否弄到足够的经费。

另外Iridium -NEXT所需的29亿美元中有18亿来自法国的信贷Coface(不知这和Thales获得卫星合同有没有联系)
Iridium will select one more launch provider as an alternative to the Falcon 9, but the company's top executive made it clear SpaceX will launch the bulk of the constellation.  "That $492 million figure would launch all 72 satellites in our constellation," said Matt Desch, Iridium's CEO.  In an interview Wednesday, Desch said Iridium will also seek an alternate satellite dispenser to go along with the other launch provider. Although Desch declined to discuss other launch options, Russian and Chinese vehicles could compete for the work.  In the first round of competition, SpaceX came out well ahead of other companies with the best bang for the buck, according to Iridium.  
"I don't know that anyone would be able to give you the value for capability that SpaceX does," Desch said.

The $2.9 billion rejuvenation program is being partially financed by a $1.8 billion credit facility from Coface, the official French export credit agency. Coface has issued a guarantee for 95 percent of the $1.8 billion credit line.
