National Space Society Congratulates SpaceX on the Success of CRS-3 and the First Flight of the Falcon 9R

The Washington DC-based National Space Society (NSS) congratulates SpaceX on the successful launch of Commercial Resupply Services 3 (CRS-3) from Cape Canaveral’s Space Launch Complex 40 (SLC-40) to the International Space Station (ISS) on April 18th at 3:25 pm EDT.  NSS Executive Senior Operating Officer Bruce Pittman said, “The successful reusability tests of the Falcon 9 v1.1 during the CRS-3 mission are a vital step on the path to dramatically reducing the cost of access to space.”

The National Space Society will present two special awards to SpaceX at their 2014 International Space Development Conference (ISDC).  Elon Musk, SpaceX Chief Designer and CTO, will accept the Robert A Heinlein Memorial Award.  Gwynne R. Shotwell, SpaceX President and Chief Operating Officer, will accept the Space Pioneer Award for the Entrepreneurial Business category.

The Dragon capsule berthed with the ISS at 9:06 AM EDT Sunday April 20th.  This is the first flight of the upgraded Falcon 9 v1.1 to the ISS, and the fourth overall flight of the v1.1 version.  In addition to carrying a record up mass (cargo) to the ISS, the Falcon 9 v1.1 demonstrated for the first time the unfolding of the landing legs on the first stage.   CRS-3 was part of a series of tests of reusable spacecraft technology that are planned to eventually lead to the full re-use of the Falcon 9.   If this occurs, it will drive a revolution in access to space via lowering launch costs.

The Dragon capsule pressurized area carried a record of one GLACIER and two MERLIN freezers for transporting experiment samples, a replacement Extravehicular Mobility Unit (EMU), or in everyday English, a spacesuit, plus additional supplies of food, water, and personal items.  The unpressurized Dragon trunk contained the Optical Payload for Lasercomm Science (OPALS) and the High Definition Earth Viewing (HDEV) package made up of four commercial HD cameras.  Dragon also brought VEG-01, a plant growth chamber to the ISS, where it will be used for experimental food production.

As expected for this early test flight, SpaceX did not recover the first stage, which “soft landed” in the ocean.  At this time it appears that CRS-3 met SpaceX’s reusability milestones, including first stage re-ignition to slow the first stage on its return.  Reusability tests of the Falcon 9 will continue throughout 2014, with a target of full first stage reuse by the end of 2014 or early 2015.

On Thursday April 17th the SpaceX Falcon 9R flew for the first time from McGregor, Texas, to a height of 250 m [VIDEO BELOW].  The Falcon 9R is a 3-engine successor to the single-engine “Grasshopper” and will continue the development of reusable SpaceX rocket technology.  Later this summer the Falcon 9R will move to Spaceport America in New Mexico for high-altitude test flights.

Dr. John Lewis Wins National Space Society’s Space Pioneer Award for Science and Engineering

The National Space Society takes great pleasure in awarding a 2014 Space Pioneer Award in the Science and Engineering category to Dr. John S. Lewis.  This award is in recognition of his major contributions to the study of the formation and chemistry of asteroids and comets, and his effective work in explaining and promoting both the risks and benefits asteroids offer through his publications.  NSS will present the Space Pioneer Award to Dr. Lewis during the dinner on Thursday, May 15, at its annual conference, the 2014 International Space Development Conference (ISDC).  The conference will be held at the Sheraton Gateway Hotel in Los Angeles, CA. and will run from May 14-18, 2014.

About Dr. John S. Lewis:

Dr. John S. LewisDr. Lewis is Professor Emeritus of Planetary Sciences and Co-Director of the Space Engineering Research Center at the University of Arizona.  After his degree programs at Princeton, Dartmouth, and University of California at San Diego, he taught space science and cosmo-chemistry at MIT, before moving to the University of Arizona.  His work on the chemistry and composition of asteroids and comets has resulted in a series of significant scientific publications.  He has written 19 books, including graduate and undergraduate texts and popular science books.  He has authored over 150 scientific publications.

His clearly written popular books, (such as Rain of Iron and Ice: The Very Real Threat of Comet and Asteroid Bombardment; Mining the Sky: Untold Riches from the Asteroids, Comets and Planets; and Worlds Without End: The Exploration of Planets Known and Unknown) have contributed in a major way to public understanding of space dangers and space resources.  He began publishing on this topic when most people could not even conceive of using space resources.

It has always been a risk for professional scientists to write or communicate to the public though the popular media, even though competent communication in this area is always badly needed.  With the advent of both miniature space probes (allowing inexpensive investigation of asteroidal resources), and the imminent availability of reusable rockets (to reduce launch costs and thus allow high mass space operations), the prospect of actual recovery and use of space materials is now much more believable.  His association with Deep Space Industries as Chief Scientist underscores the new reality.  His service as a member of the NSS Board of Governors is also noted with appreciation.

Orbital’s Antares/Cygnus Team Wins National Space Society’s Space Pioneer Award for Science and Engineering

The National Space Society takes great pleasure in awarding a 2014 Space Pioneer Award for the Science and Engineering category to Orbital Science Corporation’s Antares/Cygnus Team. The National Space Society will present the Space Pioneer Award to Mr. Frank Mauro, Vice President and CRS Program Director, Mr. Mike Pinkston, the Antares Program Manager, and Mr. Frank Culbertson, Jr, Executive Vice President and General Manager of Orbital’s Advanced Programs Group. The award presentation will take place on Friday, May 16, 2014, at NSS’s annual conference, the 2014 International Space Development Conference (ISDC). The conference will be held at the Sheraton Gateway Hotel in Los Angeles, CA., from May 14-18, 2014.

About Orbital Sciences Antares/Cygnus Team:

The achievements of Orbital’s Antares/Cygnus Team at Orbital Science Corporation included the development, construction, launch and successful operation of the Antares booster and Cygnus spacecraft under NASA’s COTS/CRS program. CRS stands for Commercial Resupply Services. Orbital’s Headquarters are in Dulles, VA, and its Launch vehicle Program Offices are located in Chandler, AZ.

About the Antares/Cygnus project:

Antares/Cygnus

Orbital Sciences’ Antares rocket and Cygnus spacecraft.

As a private company Orbital sucessfully designed, integrated, and built both a midsized Antares liquid-fuel launch vehicle (their first) and a Cygnus orbital tug with a cargo canister. This was done using off-the-shelf technology, modified where necessary, from an international network of suppliers. One demonstration and one commercial flight were accomplished in 2013 with rendezvous and docking with and delivery of materials to the Space Station both times. The spacecraft can deliver up to 2 metric tons of cargo to the Space Station. Essentially flawless performance of the Antares booster and the Cygnus cargo vehicle on all flights so far has demonstrated Orbital’s success in getting the design right the first time. Antares will also become available for cost effectively launching mid-sized payloads comparable to the retiring Delta-II. It is designed to place 5 metric tons into orbit, and all 3 flights have been successful. The Cygnus service and propulsion module can also be regarded as a prototype for a flexible design space tug to move large external cargo placed in orbit to the Space Station.

New Watershed for Space Solar Power

The Case for Space Solar PowerBook Review: The Case for Space Solar Power, by John C. Mankins

Reviewed by: Paul Werbos, Executive Vice President, National Space Society

If you, like me, are one of those people who really want to do the most you can “to make the dream real,” you need to have a copy of this book on your shelves so that you can read it, reread it, and go back for all the important details. If you could only afford to have one book on your shelves, this should be it.

This book by John Mankins is a major milestone in doing the work required to translate the National Space Society’s general vision into a concrete reality with a viable business case. The author was the leader at NASA of virtually all the useful work on space solar power (SSP) by the US government in the last 25 years, so this book is a unique and authoritative source. Mankins also led the efforts in human and robotic technology in the first round of Bush’s “return to the Moon” program, and this book tells you a lot about what has been going on in those areas as well. In the final section, the book gets deep into concrete business plan options.

Not only does this book provide the blueprint for providing Earth with limitless clean energy, the book also offers a whole new basis for solid, realistic hope that we might succeed after all in the kind of vision which Gerard O’Neill inspired decades ago, where humans settle space in an economically sustainable way, beaming energy to Earth as part of a growing space economy.

Back in the late 1970s, when there was a lot of hope for SSP but the designs were unproven and questionable, many energy experts walked away and never looked back. In the 1990s, Mankins led the NASA Fresh Look work which exposed what was wrong with the old designs, and found new designs that would work but were still too expensive. When John and I worked together in a National Science Foundation study of enabling technologies for SSP in 2002, the most serious life-cycle cost estimates for the best available designs were still about 20 cents per kwh for the electricity. That was still more expensive than the average we pay for electricity generation today (about ten cents), and it required improvements in launch technology which were not then on the horizon.

But now, in this book, Mankins presents a new design concept, SPS-ALPHA (Solar Power Satellite via Arbitrarily Large Phased Array), for which the best guess on cost is only 9 cents per kwh. This year there is also new hope for launch costs, which is a necessary complement to better design and more realistic costs.

The great beauty of SPS-ALPHA is that it relies on a “Lego” kind of approach, building up a huge structure from modules which all weigh less than a ton. This gets rid of the need for heavy lift vehicles, and we can use whatever gets us to space most cheaply.

Some people may be disappointed that Mankins’ plan for SSP does not provide for many humans in space, but that is part of the plan’s strength in reducing cost. The Mankins plan instead shows the way to build up the infrastructure we need in space before we can have a realistic chance to expand human settlement further. If we fulfill that plan, there will be ever more opportunity and need to bring more and more humans along, step by step, perhaps starting out with a kind of swarm city more like a giant expansion of the International Space Station (but with a net positive revenue flow) than like the habitats we will build eventually.

As a matter of honesty, I have to say that the book does not tell us everything we need to know to make the dream a reality. The book tells us a huge amount about competing designs for SSP, some of which might work out better after ALPHA paves the way. But there are other possibilities in the same design space, such as new ideas from the Naval Research Labs about how to handle heat flow issues within the ALPHA approach, and there are additional approaches to reducing launch costs. Nevertheless, Mankins’ book is the game plan for bringing SSP itself to reality. To make a positive difference in the game, we need to have that game plan close at hand, not just on our bookshelves but in all of our strategic thinking for all of the things we can do to help.

The Case for Space Solar Power is available in hard cover and in an inexpensive Kindle edition from Amazon. If you don’t have a Kindle, there are free Kindle reader apps at tinyurl.com/kindlereaderapps that enable you to read it on your computer or mobile device.

MIT team proposes storing extra rocket fuel in space for future missions

By Jennifer Chu, MIT News Office

Future lunar missions may be fueled by gas stations in space, according to MIT engineers: A spacecraft might dock at a propellant depot, somewhere between the Earth and the Moon, and pick up extra rocket fuel before making its way to the lunar surface.

Orbiting way stations could reduce the fuel a spacecraft needs to carry from Earth — and with less fuel onboard, a rocket could launch heavier payloads, such as large scientific experiments.

Over the last few decades, scientists have proposed various designs, such as building a fuel-manufacturing station on the Moon and sending tankers to refill floating depots. But most ideas have come with hefty price tags, requiring long-term investment.

The MIT team has come up with two cost-efficient depot designs that do not require such long-term commitment. Both designs take advantage of the fact that each lunar mission carries a supply of “contingency propellant” — fuel that’s meant to be used only in emergencies. In most cases, this backup fuel goes unused, and is either left on the Moon or burned up as the crew re-enters the Earth’s atmosphere.

Instead, the MIT team proposes using contingency propellant from past missions to fuel future spacecraft. For instance, as a mission heads back to Earth, it may drop a tank of contingency propellant at a depot before heading home. The next mission can pick up the fuel tank on its way to the Moon as its own emergency supply. If it ends up not needing the extra propellant, it can also drop it at the depot for the next mission — an arrangement that the team refers to as a “steady-state” approach.

A depot may also accumulate contingency propellant from multiple missions, part of an approach the researchers call “stockpiling.” Spacecraft heading to the Moon would carry contingency propellant as they normally would, dropping the tank at a depot on the way back to Earth if it’s not needed; over time, the depot builds up a large fuel supply. This way, if a large lunar mission launches in the future, its rocket wouldn’t need a huge fuel supply to launch the heavier payload. Instead, it can stop at the depot to collect the stockpiled propellant to fuel its landing on the Moon.

“Whatever rockets you use, you’d like to take full advantage of your lifting capacity,” says Jeffrey Hoffman, a professor of the practice in MIT’s Department of Aeronautics and Astronautics. “Most of what we launch from the Earth is propellant. So whatever you can save, there’s that much more payload you can take with you.”

Hoffman and his students — Koki Ho, Katherine Gerhard, Austin Nicholas, and Alexander Buck — outline their depot architecture in the journal Acta Astronautica.

Pickup and drop-off in space

The researchers came up with a basic mission strategy to return humans to the Moon, one slightly different from that of the Apollo missions. During the Apollo era, spacecraft circled close to the lunar equator — a route that required little change in direction, and little fuel to stay on track. In the future, lunar missions may take a more flexible approach, with the freedom to change course to explore farther reaches of the Moon — such as the polar caps, for evidence of water — a strategy that would require each spacecraft to carry extra fuel to change orbits.

Working under the assumption of a more global exploration strategy, the researchers designed a basic architecture involving a series of stand-alone missions, each exploring the surface of the Moon for seven to 14 days. This mission plan requires that a spacecraft returning to Earth must change its orbital plane when needed. Under this basic scenario, missions could operate under existing infrastructure, without fuel depots, meaning that each spacecraft would carry its own supply of contingency propellant.

The researchers then drew up two depot designs to improve the efficiency of the basic scenario. In both designs, depots would be stationed at Lagrange points — regions in space between the Earth, Moon, and sun that maintain gravitational equilibrium. Objects at these points remain in place, keeping the same relative position with respect to the Earth and the Moon.

Hoffman says that ideally, transferring fuel between the depot and a spacecraft would simply involve astronauts or a robotic arm picking up a tank. The alternative — siphoning fuel from tank to tank like you would for your car — is a bit trickier, as liquid tends to float in a gravity-free environment. But, Hoffman says, it’s doable.

“In building the International Space Station, every time a new module is added, we’ve had to hook up new fluid connections,” Hoffman says. “It’s not a trivial design problem, but it can be done.”

‘Creating value … against political uncertainty’

The main drawbacks for both depot designs include maintenance; keeping depots within the Lagrange point; and preventing a phenomenon, called “boil-off,” in which fuel that’s not kept at cold-enough temperatures can boil away. If scientists can find ways around these challenges, Hoffman says, gas stations in space could be an efficient way to support large lunar explorations.

“One of the problems with large space programs is, you invest a huge amount in building up the infrastructure, and then a program gets canceled,” Hoffman says. “With depot architectures, you’re creating value which is robust against political uncertainty.”

The paper came out of two MIT classes taught by Hoffman: 16.851 (Satellite Engineering) and 16.89 (Space Systems Engineering), in which students also looked at redesigning a lunar lander and evaluated different approaches to landing on the Moon.

James Head, a professor of geological sciences at Brown University, says the group’s two approaches optimize the possibility of both near-lunar missions and more ambitious, longer-duration missions to more distant destinations.

“Currently, NASA is once again considering circumlunar human operations and developing architectures for moving on to Mars,” Head says. “So this paper is extremely important and timely in the context of developing NASA plans for human exploration beyond low Earth orbit.”

National Space Society Supports 2015 NASA Commercial Crew Budget

The Washington DC-based National Space Society (NSS) has been a consistent supporter of NASA’s Commercial Crew program to ferry astronauts to the International Space Station (ISS).  In the NSS position paper on the NASA Commercial Crew Program released today, the Society strongly endorses $848 million in the 2015 NASA budget for Commercial Crew, along with the $250 million supplemental Commercial Crew request.  Furthermore, the $171 million “hold” placed on the program last year should be removed.

At a time when the availability of the Russian supplied Soyuz, our current sole method of getting American astronauts to the ISS (at $70 million per seat), is being increasingly questioned and political relations with Russia are deteriorating, we need to move Commercial Crew to the top of NASA’s priority list.

NSS believes, however, that the nature of the Commercial Crew program is as important as the amount of funding.   Commercial Crew must support a minimum of two independent American providers of crewed access to ISS.   Failure to provide this level of capability will lead to rising costs and hinder the growth of a vigorous private commercial launch industry that will lead to a vibrant, sustainable commercial space industry and the high tech jobs growth that it will create.  In addition, NSS believes the Commercial Crew program will have adequate safety, and should proceed without further funding shortfall-based delays.

NSS also endorses the recent decision by the Obama administration to extend the life of the ISS by four years to 2024.  NASA should take additional steps to further extend both the life and the capabilities of the ISS, including using the Commercial Crew vehicles to support a larger ISS crew, creating greater science, technology and commercial output.

NSS Executive Vice President Paul Werbos summed up the situation.  “We face great uncertainty in our ability to access the ISS.  We can develop a competitive, commercially successful American means to do this.  There is little or no benefit to waiting.  Let’s do it.”

First Falcon Heavy Launch Delayed Until Next Year

Aviation Week reports:

Although it was initially slated to debut this year, SpaceX founder, CEO and Chief Designer Elon Musk says the company’s production schedule is too tight to support a test flight of the heavy-lift rocket from Vandenberg AFB, Calif., in 2014.

“We need to find three additional cores that we could produce, send them through testing and then fly without disrupting our launch manifest,” Musk said in a Feb. 20 interview. “I’m hopeful we’ll have Falcon Heavy cores produced approximately around the end of the year. But just to get through test and qualification, I think it’s probably going to be sometime early next year when we launch.”

Mercury MESSENGER Team Wins National Space Society’s Space Pioneer Award for Science and Engineering

The National Space Society takes great pleasure in awarding its 2014 Space Pioneer Award for the Science and Engineering category to the (Mercury) MESSENGER Team.  MESSENGER stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging.  This spacecraft entered an orbit around the planet Mercury and conducted an extensive scientific survey of the entire planet, the first human object to do so.  With this award, NSS recognizes both the importance of the first dedicated probe to orbit Mercury and the significance of the scientific results already released.

The National Space Society will present the Space Pioneer Award to MESSENGER project representatives Drs. Sean C. Solomon, Larry R. Nittler and Ralph McNutt at NSS’s annual conference, the 2014 International Space Development Conference (ISDC).  The conference will be held at the Sheraton Gateway Hotel in Los Angeles, CA.  The ISDC will run from May 14-18, 2014.

About the MESSENGER Team:

The Principal Investigator for the Messenger Team is Dr. Sean C. Solomon. He also directs the prestigious Lamont-Doherty Earth Observatory at Columbia University.  Dr. Larry R. Nittler is MESSENGER’s Deputy Principal Investigator. Dr. Ralph McNutt is MESSENGER’s Project Scientist. The historic achievements of the MESSENGER Team (after construction and launch of the spacecraft) include successfully placing the spacecraft accurately into its intended orbit around Mercury on March 18, 2011, after a series of six critical flybys of the Earth, Venus, and Mercury itself.  Besides the critical contribution of accurately mapping Mercury’s surface, the science results have confirmed the presence of water ice and organic chemicals at the poles, and the fact that Mercury’s magnetic field is offset to the north substantially from its equator.

About the MESSENGER Mission:

MESSENGER confirmed suspicions of major regional volcanism and mapped global patterns of thrust fault scarps that show Mercury has contracted several times more than Mariner 10 data indicated.  Global elemental and mineralogical mapping confirmed Mercury has a low-iron crustal mineralogy, but unexpectedly showed sulfur, potassium and other volatile elements are abundant, upsetting high temperature models of Mercury’s formation.  MESSENGER has discovered pitted “hollows” with bright halos, found in many craters, which appear to involve volatile loss but their formation mechanism remains enigmatic.
