It was short but sweet. SpaceX conducted a 2-second static fire test of their Falcon 9 rocket that will send the first COTS flight to the International Space Station. “Woohoo, rocket hold down firing completed and all looks good!!” Tweeted SpaceX CEO and founder Elon Musk. SpaceX’s Twitter feed said with the successful firing, engineers will now review data as they continue to prepare for the upcoming mission, slated to launch on May 7.

A first attempt was aborted with 30 seconds left in the countdown, due to “overly restrictive redline on second stage engine position.” Engineers recycled all the rocket’s systems and began another countdown.

Fire and smoke erupted just briefly from the base of the rocket, and there seemed to be a bit of confusion on the webcast, as the word “abort” was used, but then there was word of success and the webcast ended abruptly.

For the static fire test, the nine Merlin engines on the first stage of the Falcon 9 rocket were ignited at 20:15 UTC (4:15 p.m. EDT). The test was part of a full dress rehearsal for the SpaceX team. Last week was a final full simulation between NASA and SpaceX for the series of demonstration maneuvers and tests the Dragon capsule will make as it approaches the ISS; then the astronauts on board will capture and berth the cargo capsule to the Harmony module’s Earth-facing docking port.

If the abort problem had occured on the launch day, there would be no second attempt; there is no recycling of the systems for an actual launch. Additionally, the Falcon 9 can only attempt launch every 3 days because of limited propellant on Dragon capsule. SpaceX needs to ensure there is enough propellant on board Dragon for the pre-berthing maneuvers and tests.

If the Falcon 9 launch is delayed by weather or technical problems, another attempt could be made on May 10, but after that they would have to until after the launch of a Russian Soyuz spacecraft that will bring three new crew members to the space station. That mission is scheduled for launch from the Baikonur Cosmodrome in Kazakhstan on May 14, and would dock two days later.

The launch of the Falcon 9 and Dragon has been delayed from its initial planned flight in February, but with today’s apparently successful test, SpaceX and NASA are hopeful for going forward with next week’s launch.

SpaceX is one of two companies, along with Orbital Sciences, competing for contracts to deliver cargo to low Earth orbit for NASA under the Commercial Orbital Transportation System program.

The launch is currently set for 13:38 UTC (9:38 a.m. EDT) on Monday.

Planetary Resources: The Video

Planetary Resources, Inc. has announced its plan to mine Near Earth Asteroids for their raw resources, ranging from water to precious metals like platinum. Using their Arkyd line of spacecraft, they will head to NEOs for exploration and extraction. One of the founders, Eric Anderson said they will launch their first spacecraft within 24 months, and eventually build ‘gas stations’ in space to enable deep space exploration.

The founders of this company say that resource extraction from asteroids will deliver multiple benefits to humanity and could be valued at billions of dollars annually. “The effort will tap into the high concentration of precious metals found on asteroids and provide a sustainable supply to the ever-growing population on Earth,” they said.

Last week a new company backed by a number of high-tech billionaires said they would be announcing a new space venture, and there was plenty of speculation of what the company –– called Planetary Resources — would be doing. Many ventured the company would be an asteroid mining outfit, and now, the company has revealed its purpose really is to focus on extracting precious resources such as metals and rare minerals from asteroids. “This innovative start-up will create a new industry and a new definition of ‘natural resources,’” the group said.

Is this pie in the sky or a solid investment plan?

It turns out this company has been in existence for about three years, working quietly in the background, assembling their plan.

The group includes X PRIZE CEO Peter Diamandis, Space Adventures founder Eric Anderson, Google executives K. Ram Shriram, Larry Page and Eric Schmidt, filmmaker James Cameron, former Microsoft chief software architect Charles Simonyi — a two-time visitor to the International Space Station — and Ross Perot Jr.
Even though their official press conference isn’t until later today, many of the founders started talking late yesterday. The group will initially focus on developing Earth orbiting telescopes to scan for the best asteroids, and later, create extremely low-cost robotic spacecraft for surveying missions.

A demonstration mission in orbit around Earth is expected to be launched within two years, according to the said company co-founders, and within five to 10 years, they hope to go from selling observation platforms in orbit to prospecting services, then travel to some of the thousands of asteroids that pass relatively close to Earth and extract their raw materials and bring them back to Earth.

But this company also plans to use the water found in asteroids to create orbiting fuel depots, which could be used by NASA and others for robotic and human space missions.

“We have a long view. We’re not expecting this company to be an overnight financial home run. This is going to take time,” Anderson said in an interview with Reuters.

President and Chief Engineer Chris Lewicki talked with Phil Plait yesterday and said “This is an attempt to make a permanent foothold in space. We’re going to enable this piece of human exploration and the settlement of space, and develop the resources that are out there.”

Lewicki was Flight Director for the NASA’s Spirit and Opportunity Mars rover missions, and also Mission Manager for the Mars Phoenix lander surface operations. He added that the plan structure is reminiscent of that of Apollo: have a big goal in mind, but make sure the steps along the way are practical.

Another of the aims of Planetary Resources is to open deep-space exploration to private industry, much like the $10 million Ansari X Prize competition, which Diamandis created. In previous talks, Diamandis has estimated that a small asteroid is worth about “20 trillion dollars in the platinum group metal marketplace.”

“The resources of Earth pale in comparison to the wealth of the solar system,” Eric Anderson told Wired.

The company will reveal more details in their press conference today (April 24) at 10:30 AM PDT | 12:30 PM CDT | 1:30 PM EDT | 5:30 UTC. You can watch at this link.

SpaceX Launch to Space Station Delayed

[/caption]

The historic flight of the first commercial transport to the International Space Station will have to wait at least another week. “After reviewing our recent progress, it was clear that we needed more time to finish hardware-in-the-loop testing and properly review and follow up on all data,” SpaceX said in a statement today. “While it is still possible that we could launch on May 3rd, it would be wise to add a few more days of margin in case things take longer than expected. As a result, our launch is likely to be pushed back by one week, pending coordination with NASA.”

And so, the launch which was going to take place on April 30 is now pushed back to no earlier than May 7. A static fire test of the Falcon 9 rocket that SpaceX had hoped to do today was slipped to the 27th, making the all the preparations for the launch next Monday a tight squeeze.

When launched, the Dragon will arrive at the ISS one to three days later and once there, Dragon will begin the demonstrations related to the Commercial Orbital Transportation Services Phase 2 agreements (COTS 2) to show proper performance and control in the vicinity of the ISS, while remaining outside the Station’s safe zone. Then, if all goes well, Dragon will receive approval to begin the COTS 3 activities, where it will gradually approach within a few meters of the ISS, allowing astronauts to reach out and grapple Dragon with the Station’s robotic arm and then maneuver it carefully into one of the docking ports.

How to Capture a Dragon in Space

With the upcoming historic launch of the SpaceX Dragon capsule to the International Space Station, astronauts in orbit have been getting ready for the first commercial spacecraft that will bring supplies to the station. Astronauts Don Pettit and André Kuipers will be manually capturing and berthing the Dragon capsule, using the ISS’s Canadarm2. Originally, current station commander Dan Burbank was to be the main arm operator, but with the delay in Dragon’s launch (it was originally scheduled for February 2012), Burbank will already be back on Earth by the time Dragon reaches the station, currently scheduled for May 3. So now, Pettit and Kuipers have had to take over the duties and learn their new jobs while in space. Without the high-tech simulators that NASA has at Johnson Space Center, how do the astronauts prepare and practice for this important event?

“We have a really neat capability here on Station,” Pettit said during a press conference last week. “I have it set up all the time, so I wake up in the morning and have a bag of coffee in my mouth and a cinnamon scone in one hand and flying the simulator with the other.”

The crew actually has two ways to practice for Dragon’s arrival.

“One is actually flying (practicing with) the Canadarm, which is the world’s best trainer,” Pettit said, “and then on station we have two space station computers which double as an Arm simulator, and it has a full set of the Arm hand controllers – the setup, which we call Robot allows us to fly track and capture trajectories just as if we were in the simulators in Houston.”

Initially Burbank would have been the main arm officer, with Pettit and Kuipers assisting. Now, Pettit and Kuipers will have to complete the task themselves, with the two of them doing all the things that the three of them were originally trained to do.

For the capture and berthing, Pettit and Kuipers will be in the Cupola, with Pettit as prime operator and Kuipers as second arm operator. “We will have arm operation in the (Destiny) lab as a ‘hot backup’ just in case of contingencies, and we can activate it there if needed.”

The two astronauts will use the Station’s Canadarm2 to first grab the spacecraft and then maneuver it into place to mate with the Harmony module’s Earth-facing docking port.

Pettit said the on-orbit training has been invaluable. “It is really good to have that type of capability,” he said.

The following animation from the Canadian Space Agency shows just how complex it is to capture a Dragon in space.

SpaceX’s launch and Dragon’s arrival will be the premiere test flight in NASA’s new strategy to resupply the ISS with privately developed rockets and cargo carriers under the Commercial Orbital Transportation Services (COTS) initiative. Even though it is technically a est flight, NASA isn’t about to pass up an opportunity to send supplies to the station. Dragon will carry about nearly 521 kg (1,150 pounds) of cargo, mainly food and some spare parts for the ISS. When Dragon departs, the station crew will load nearly 680 kg (1,500 pounds) of cargo to be sent back to Earth, since the Dragon capsule won’t burn up in the atmosphere like other supply ships — it will be recovered in the ocean.

NanoRacks and CASIS Put Research on the Universe’s Front Porch

The Center for the Advancement of Science in Space (CASIS) has opened part of the ISS exterior to research experiments via NanoRacks, a company providing plug-and-play platforms aboard the Station to third-party research organizations. For the first time, commercial experiments will have a dedicated external space aboard the ISS, putting them on “the front porch of the Universe.”

Since 2009 NanoRacks has been providing research institutions with shoebox-sized consoles that can house customized experiments for installation inside the U.S. National Laboratory on board the ISS.

On April 12 CASIS announced a $1.5 million deal with NanoRacks that will allow an external “NanoLabs” platform to be installed on the Japanese Kibo module. The structure will provide research spaces up to 8″ square that will be exposed to the environment of space. (Watch a video of the NanoLabs concept below.)

Through the CASIS investment, as many as four companies will be able to fly experiments for little or no cost.

A formal solicitation to research companies and private enterprises for payload proposals will be issued by CASIS in June. The NanoLabs platform is expected to be ready for flight by 2013 — a full year ahead of schedule.

“CASIS’ investment ensures that U.S. researchers will have access to the ISS External Platform far sooner than otherwise expected,” stated Jeffrey Manber, Managing Director of NanoRacks . “This program will enable faster innovation and spiral development for payloads — an opportunity that has not previously been made available to the commercial marketplace.”

Read the full press release here.

NanoRacks LLC was formed in 2009 to provide quality hardware and services for the U.S. National Laboratory onboard the International Space Station. The company operates the first commercial laboratory in low-earth orbit. The Center for the Advancement of Science in Space (CASIS) was selected by NASA in July 2011 to maximize use of the International Space Station U.S. National Laboratory through 2020.

Robotics Refueling Research Scores Huge Leap at Space Station

A combined team of American and Canadian engineers has taken a major first step forward by successfully applying new, first-of-its-kind robotics research conducted aboard the International Space Station (ISS) to the eventual repair and refueling of high value orbiting space satellites, and which has the potential to one day bring about billions of dollars in cost savings for the government and commercial space sectors.

Gleeful researchers from both nations shouted “Yeah !!!” – after successfully using the Robotic Refueling Mission (RRM) experiment – bolted outside the ISS- as a technology test bed to demonstrate that a remotely controlled robot in the vacuum of space could accomplish delicate work tasks requiring extremely precise motion control. The revolutionary robotics experiment could extend the usable operating life of satellites already in Earth orbit that were never even intended to be worked upon.

“After dedicating many months of professional and personal time to RRM, it was a great emotional rush and a reassurance for me to see the first video stream from an RRM tool,” said Justin Cassidy in an exclusive in-depth interview with Universe Today. Cassidy is RRM Hardware Manager at the NASA Goddard Spaceflight Center in Greenbelt, Maryland.

And the RRM team already has plans to carry out even more ambitious follow on experiments starting as soon as this summer, including the highly anticipated transfer of fluids to simulate an actual satellite refueling that could transfigure robotics applications in space – see details below !

All of the robotic operations at the station were remotely controlled by flight controllers from the ground. The purpose of remote control and robotics is to free up the ISS human crew so they can work on other important activities and conduct science experiments requiring on-site human thought and intervention.

Over a three day period from March 7 to 9, engineers performed joint operations between NASA’s Robotic Refueling Mission (RRM) experiment and the Canadian Space Agency’s (CSA) robotic “handyman” – the Dextre robot. Dextre is officially dubbed the SPDM or Special Purpose Dexterous Manipulator.

On the first day, robotic operators on Earth remotely maneuvered the 12-foot (3.7 meter) long Dextre “handyman” to the RRM experiment using the space station’s Canadian built robotic arm (SSRMS).

Dextre’s “hand” – technically known as the “OTCM” – then grasped and inspected three different specialized satellite work tools housed inside the RRM unit . Comprehensive mechanical and electrical evaluations of the Safety Cap Tool, the Wire Cutter and Blanket Manipulation Tool, and the Multifunction Tool found that all three tools were functioning perfectly.

“Our teams mechanically latched the Canadian “Dextre” robot’s “hand” onto the RRM Safety Cap Tool (SCT). The RRM SCT is the first on orbit unit to use the video capability of the Dextre OTCM hand,” Cassidy explained.

“At the beginning of tool operations, mission controllers mechanically drove the OTCM’s electrical umbilical forward to mate it with the SCT’s integral electronics box. When the power was applied to that interface, our team was able to see that on Goddard’s large screen TVs – the SCT’s “first light” video showed a shot of the tool within the RRM stowage bay (see photo).

“Our team burst into a shout out of “Yeah!” to commend this successful electrical functional system checkout.”

Dextre then carried out assorted tasks aimed at testing how well a variety of representative gas fittings, valves, wires and seals located on the outside of the RRM module could be manipulated. It released safety launch locks and meticulously cut two extremely thin satellite lock wires – made of steel – and measuring just 20 thousandths of an inch (0.5 millimeter) in diameter.

“The wire cutting event was just minutes in duration. But both wire cutting tasks took approximately 6 hours of coordinated, safe robotic operations. The lock wire had been routed, twisted and tied on the ground at the interface of the Ambient Cap and T-Valve before flight,” said Cassidy.

This RRM exercise represents the first time that the Dextre robot was utilized for a technology research and development project on the ISS, a major expansion of its capabilities beyond those of robotic maintenance of the massive orbiting outpost.

Altogether the three days of operations took about 43 hours, and proceeded somewhat faster than expected because they were as close to nominal as could be expected.

“Days 1 and 2 ran about 18 hours,” said Charles Bacon, the RRM Operations Lead/Systems Engineer at NASA Goddard, to Universe Today. “Day 3 ran approximately 7 hours since we finished all tasks early. All three days baselined 18 hours, with the team working in two shifts. So the time was as expected, and actually a little better since we finished early on the last day.”

“For the last several months, our team has been setting the stage for RRM on-orbit demonstrations,” Cassidy told me. “Just like a theater production, we have many engineers behind the scenes who have provided development support and continue to be a part of the on-orbit RRM operations.”

“At each stage of RRM—from preparation, delivery, installation and now the operations—I am taken aback by the immense efforts that many diverse teams have contributed to make RRM happen. The Satellite Servicing Capabilities Office at NASA’s Goddard Space Flight Center teamed with Johnson Space Center, Kennedy Space Center (KSC), Marshall Space Flight Center and the Canadian Space Agency control center in St. Hubert, Quebec to make RRM a reality.”

“The success of RRM operations to date on the International Space Station (ISS) using Dextre is a testament to the excellence of NASA’s many organizations and partners,” Cassidy explained.

The three day “Gas Fittings Removal task” was an initial simulation to practice techniques essential for robotically fixing malfunctioning satellites and refueling otherwise nominally operating satellites to extend to hopefully extend their performance lifetimes for several years.

Ground-based technicians use the fittings and valves to load all the essential fluids, gases and fuels into a satellites storage tanks prior to launch and which are then sealed, covered and normally never accessed again.

“The impact of the space station as a useful technology test bed cannot be overstated,” says Frank Cepollina, associate director of the Satellite Servicing Capabilities Office (SSCO) at NASA’s Goddard Space Flight Center in Greenbelt, Md.

“Fresh satellite-servicing technologies will be demonstrated in a real space environment within months instead of years. This is huge. It represents real progress in space technology advancement.”

Four more upcoming RRM experiments tentatively set for this year will demonstrate the ability of a remote-controlled robot to remove barriers and refuel empty satellite gas tanks in space thereby saving expensive hardware from prematurely joining the orbital junkyard.

The timing of future RRM operations can be challenging and depends on the availability of Dextre and the SSRMS arm which are also heavily booked for many other ongoing ISS operations such as spacewalks, maintenance activities and science experiments as well as berthing and/or unloading a steady stream of critical cargo resupply ships such as the Progress, ATV, HTV, Dragon and Cygnus.

Flexibility is key to all ISS operations. And although the station crew is not involved with RRM, their activities might be.

“While the crew itself does not rely on Dextre for their operations, Dextre ops can indirectly affect what the crew can or can’t do,” Bacon told me. “For example, during our RRM operations the crew cannot perform certain physical exercise activities because of how that motion could affect Dextre’s movement.”

Here is a list of forthcoming RRM operations – pending ISS schedule constraints:

  • Refueling (summer 2012) – After Dextre opens up a fuel valve that is similar to those commonly used on satellites today, it will transfer liquid ethanol into it through a sophisticated robotic fueling hose.
  • Thermal Blanket Manipulation (TBD 2012)- Dextre will practice slicing off thermal blanket tape and folding back a thermal blanket to reveal the contents underneath.

  • Screw (Fastener) Removal (TBD 2012)- Dextre will robotically unscrew satellite bolts (fasteners).

  • Electrical Cap Removal (TBD 2012)- Dextre will remove the caps that would typically cover a satellite’s electrical receptacle.

RRM was carried to orbit inside the cargo bay of Space Shuttle Atlantis during July 2011 on the final shuttle mission (STS-135) of NASA’s three decade long shuttle program and then mounted on an external work platform on the ISS backbone truss by spacewalking astronauts. The project is a joint effort between NASA and CSA.

“This is what success is all about. With RRM, we are truly paving the way for future robotic exploration and satellite servicing,” Cassidy concluded.

So much for the idea that space capsules are cramped and can only carry a limited crew. SpaceX revealed a prototype for their new crew cabin design, as they conducted a joint daylong review with NASA of the Dragon crew vehicle layout. In this configuration, the Dragon will be able to carry a crew of seven, the same number the space shuttle could carry. Using a Dragon engineering model equipped with seats and representations of crew systems, they were able to get assessments and feedback from engineers and four NASA astronauts on interior amenities such as lighting, environmental control and life support systems, displays, cargo racks, and the all important seating system. The evaluators participated in human factors assessments which covered entering and exiting Dragon under both regular and emergency (that’s ‘off-nominal’ in NASA-speak) scenarios, as well as reach and visibility evaluations.

See more images from the review, below, along with a video from the initial tests of the SuperDraco engines that will power the launch escape system.

Plus, as a heads-up, SpaceX CEO Elon Musk will be on the US television show “60 Minutes” on Sunday, March 18, 2012. You can see a preview here, (which includes a touching scene of Musk talking about his heroes) and check your local listings here.

Even with all seven crewmembers in their seats, there is enough interior space for three additional people to stand and assist the crew with their launch preparations — or for the CEO to kibitz with the crew.

The seven seats mount to strong, lightweight supporting structures attached to the pressure vessel walls. Each seat can hold an adult up to 1.95 meters tall (6 feet 5 inches) and weighing 113 kg (250 lbs), and has a liner that is custom-fit for each crewmember.

SpaceX Completes Important “Wet Dress” Rehearsal Test for Upcoming Flight to Space Station

SpaceX successfully completed a key test of the Falcon 9 rocket that will fly the first commercial flight to the International Space Station. Called a ‘wet dress rehearsal,’ SpaceX brought the Falcon 9 “stack” with the Dragon capsule atop to the launch pad at Cape Canaveral on March 1, and loaded it with 76,000 gallons of highly refined kerosene and liquid oxygen fuel. Pre-liftoff operations were conducted as engineers went through a full count-down simulation, stopping at 5 seconds before ‘launch.’

SpaceX said the test was a success and was an important step on the road to the Space Station. “The test went well,” said SpaceX spokeswoman Kirstin Grantham. “Over the coming days, we will continue to review the data as we prepare for our upcoming mission.”

The launch of this historic flight will likely be April 20, or later, depending on the results of this and other tests.

After the wet dress rehearsal, the fuel was drained, and the rocket was later rolled off the launch pad on March 2, and the SpaceX said Dragon will be taken off for additional testing.

Additionally, on March 2, SpaceX conducted another test, called a 9-engine test, firing the engines for a future Falcon 9 rocket. This took place near McGregor, Texas.

As the “real” launch date approaches for the current rocket, the Falcon 9 will again be brought to the Launchpad to fire the nine first-stage engines and practice late packing of cargo in the Dragon.

“These rehearsals allow SpaceX to test out both the vehicle and the ground systems before launch,” Grantham said.

SpaceX is working towards becoming the first commercial spacecraft to dock with the ISS under NASA’s commercial orbital transportation services (COTS) commercial crew development (CCDev) programs. Later this year, another COTS company, Orbital Sciences hopes to launch their Antares rocket and Cygnus capsule from Wallops Island, Virginia.
