CAPE CANAVERAL AIR FORCE STATION, FL – Following a pair of back to back launch scrubs this week on Wednesday and Thursday due to rocket fueling issues with the liquid oxygen propellant, SpaceX has reset the blast off of their upgraded Falcon 9 rocket – carrying the commercial SES-9 television and communications satellite – to coincidentally coincide with a serene sunset on Sunday, Feb. 28.
Spectators have flocked to the Florida space coast in hopes of catching a glimpse of what could prove to be a spectacular evening streak to orbit after miserable mid-week weather finally departed the sunshine state in favor of glorious blue skies – to the delight of everyone!
SpaceX engineers are now targeting liftoff of the Cape’s first Falcon 9 launch of 2016 for 6:46 p.m. EST from SpaceX’s seaside Space Launch Complex 40 on Cape Canaveral Air Force Station, Fla. at the opening of a 97-minute launch window.
The first launch scrub on Wednesday was called some 45 minutes before launch.
“Out of an abundance of caution, the team opted to hold launch for today to ensure liquid oxygen temperatures are as cold as possible in an effort to maximize performance of the vehicle,” SpaceX said in a statement.”
The rocket and spacecraft were otherwise nominal.
“The Falcon 9 remains healthy in advance of SpaceX and SES’s mission to deliver the SES-9 satellite to Geostationary Transfer Orbit.”

The second scrub was called at 1 minute forty seconds before T zero when engineers were concerned about aspects of the liquid oxygen fuel loading and internal temperatures.
“Countdown held for the day. Teams are reviewing the data and next available launch date,” tweeted SpaceX post scrub.
SpaceX is cooling the liquid oxygen propellant in the upgraded Falcon 9 to lower temperatures compared to the rockets prior version, in order to increase its density and provide more fuel aboard the rocket for the engines to burn.
Both stages of the 229 foot tall Falcon 9 are fueled by liquid oxygen and RP-1kerosene which burn in the Merlin engines.
Air Force meteorologists are predicting an almost unheard of >95% percent chance of favorable weather conditions at launch time Sunday – which could result in an absolutely spectacular view as Falcon roars off the launch pad thunders to space, if all goes well.
The only potential concern at this time is for cumulus clouds associated with onshore flow.
A live webcast will be available at SpaceX.com/webcast beginning about 20 minutes before liftoff, at approximately 6:26 p.m. EST on Sunday, Feb. 28.
The launch window closes at approximately 8:23 p.m. EST.
The weather prognosis changes only slightly to 90 percent GO on Monday, again with a concern for cumulus clouds.
If needed, SpaceX has a backup launch opportunity reserved on the Eastern range for Monday, Feb. 29 at approximately the same time at 6:46 p.m. EST.

The goal of Sunday’s launch is to boost the commercial SES-9 television and communications satellite to a Geostationary Transfer Orbit (GTO). The satellite will be deployed approximately 31 minutes after liftoff.
The commercial launch was contracted by the Luxembourg based SES, a world-leading satellite operator. SES provides satellite-enabled communications services to broadcasters, Internet service providers, mobile and fixed network operators, and business and governmental organizations worldwide using its fleet of more than 50 geostationary satellites.

Interstellar travel will require near-light-speed to be feasible. Image: NASA
We’ve achieved amazing things by using chemical rockets to place satellites in orbit, land people on the Moon, and place rovers on the surface of Mars. We’ve even used ion drives to reach destinations further afield in our Solar System. But reaching other stars, or reducing our travel time to Mars or other planets, will require another method of travel. One that can approach relativistic speeds.
Your aim has to be really really good. Credit: UCSB Experimental Cosmology GroupWe can execute missions to Mars, but it takes several months for a vehicle to reach the Red Planet. Even then, those missions have to be launched during the most optimal launch windows, which only occur every 2 years. But the minds at NASA never stop thinking about this problem, and now Dr. Philip Lubin, Physics Professor at the University of California, Santa Barbara, may have come up with something: photonic propulsion, which he thinks could reduce the travel time from Earth to Mars to just 3 days, for a 100 kg craft.
The system is called DEEP IN, or Directed Propulsion for Interstellar Exploration. The general idea is that we have achieved relativistic speeds in the laboratory, but haven’t taken that technology—which is electromagnetic in nature, rather than chemical—and used it outside of the laboratory. In short, we can propel individual particles to near light speed inside particle accelerators, but haven’t expanded that technology to the macro level.
Directed Energy Propulsion differs from rocket technology in a fundamental way: the propulsion system stays at home, and the craft doesn’t carry any fuel or propellant. Instead, the craft would carry a system of reflectors, which would be struck with an aimed stream of photons, propelling the craft forward. And the whole system is modular and scalable.
Photonic propulsion explained.
If that’s not tantalizing enough, the system can also be used to deflect hazardous space debris, and to detect other technological civilizations. As talked about in this paper, detecting these types of systems in use by other civilizations may be our best hope for discovering those civilizations.
There’s a roadmap for using this system, and it starts small. At first, DEEP IN would be used to launch small cube satellites. The feedback from this phase would then inform the next step, which would be to test a unit for defending the ISS from space debris. From then, the systems would meet goals of increasing complexity, from launching satellites to LEO (Low-Earth Orbit) and GEO (Geostationary Orbit), all the way up to asteroid deflection and planetary defense. After that, relativistic drives capable of interstellar travel is the goal.
There are lots of questions still to be answered of course, like what happens when a vehicle at near light-speed hits a tiny meteorite. But those questions will be asked and answered as the system is developed and its capabilities grow.
Obviously, DEEP IN has the potential to bring other stars into reach. This system could deliver probes to some of the more promising exo-planets, and give humanity its first detailed look at other solar systems. If DEEP IN can be successfully scaled up, as Lubin says, then it will be a transformational technology.

On the road to restoring US Human spaceflight from US soil, SpaceX conducted a pair of key tests involving a propulsive hover test and parachute drop test for their Crew Dragon vehicle which is slated to begin human missions in 2017.
SpaceX released a short video showing the Dragon 2 vehicle executing a “picture-perfect propulsive hover test” on a test stand at the firms rocket development facility in McGregor, Texas.
The video published last week shows the Dragon 2 simultaneously firing all eight of its side mounted SuperDraco engines, during a five second test carried out on Nov. 22, 2015.
Using the SuperDragos will eventually enable pinpoint propulsive soft landings like a helicopter in place of parachute assisted landings in the ocean or on the ground.
The video clip seen below includes both full speed and slow motion versions of the test, showing the vehicle rising and descending slowly on the test stand.
Video caption: SpaceX Dragon 2 crew vehicle, powered by eight SuperDraco engines, conducts propulsive hover test firing at rocket development facility in McGregor, Texas.
The eight SuperDraco thrusters are mounted in sets 90 degrees apart around the perimeter of the vehicle in pairs called “jet packs.”
The SuperDracos generate a combined total of 33,000 lbs of thrust.
SpaceX is developing the Crew Dragon under the Commercial Crew Program (CCP) awarded by NASA to transport crews of four or more astronauts to the International Space Station.
“This test was the second of a two-part milestone under NASA’s Commercial Crew Program,” said SpaceX officials. “The first test—a short firing of the engines intended to verify a healthy propulsion system—was completed November 22, and the longer burn two-days later demonstrated vehicle control while hovering.”
The first unmanned and manned orbital test flights of the crew Dragon are expected sometime in 2017. A crew of two NASA astronauts should fly on the first crewed test before the end of 2017.

Initially, the Crew Dragon will land via parachutes in the ocean before advancing to use of pinpoint propulsive landing.
Thus SpaceX recently conducted a parachute drop test involving deployment of four red-and-white parachutes unfurling high above the desert near Coolidge, Arizona using a mass simulator in place of the capsule.

“The mass simulator and parachutes were released thousands of feet above the ground from a C-130 cargo aircraft. This test evaluated the four main parachutes, but did not include the drogue chutes that a full landing system would utilize,” said NASA.
Since the CCP program finally received full funding from Congress in the recently passed Fiscal Year 2016 NASA budget, the program is currently on track to achieve the orbital test flight milestones.
Boeing and SpaceX were awarded contracts by NASA Administrator Charles Bolden in September 2014 worth $6.8 Billion to complete the development and manufacture of the privately developed Starliner CST-100 and Crew Dragon astronaut transporters under the agency’s Commercial Crew Transportation Capability (CCtCap) program and NASA’s Launch America initiative.
The Crew Dragon will launch atop a SpaceX Falcon 9 rocket from launch Complex 39A at the Kennedy Space Center. The historic launch pad has been leased by SpaceX from NASA and is being refurbished for launches of the Falcon 9 and Falcon Heavy.

Restoring America’s ability to once again launch US astronauts to the International Space Station (ISS) from US soil on US rockets took another significant step forward when NASA ordered the first the agency’s first commercial crew rotation mission from the Hawthorne, California based-company SpaceX. NASA and SpaceX hope that the blastoff with a crew of up to four astronauts will take place by late 2017.

When we think of space travel, we tend to picture a massive rocket blasting off from Earth, with huge blast streams of fire and smoke coming out the bottom, as the enormous machine struggles to escape Earth’s gravity. Rockets are our only option for escaping Earth’s gravity well—for now. But once a spacecraft has broken its gravitational bond with Earth, we have other options for powering them. Ion propulsion, long dreamed of in science fiction, is now used to send probes and spacecraft on long journeys through space.
NASA first began researching ion propulsion in the 1950’s. In 1998, ion propulsion was successfully used as the main propulsion system on a spacecraft, powering the Deep Space 1 (DS1) on its mission to the asteroid 9969 Braille and Comet Borrelly. DS1 was designed not only to visit an asteroid and a comet, but to test twelve advanced, high-risk technologies, chief among them the ion propulsion system itself.
Ion propulsion systems generate a tiny amount of thrust. Hold nine quarters in your hand, feel Earth’s gravity pull on them, and you have an idea how little thrust they generate. They can’t be used for launching spacecraft from bodies with strong gravity. Their strength lies in continuing to generate thrust over time. This means that they can achieve very high top speeds. Ion thrusters can propel spacecraft to speeds over 320,000 kp/h (200,000 mph), but they must be in operation for a long time to achieve that speed.
An ion is an atom or a molecule that has either lost or gained an electron, and therefore has an electrical charge. So ionization is the process of giving a charge to an atom or a molecule, by adding or removing electrons. Once charged, an ion will want to move in relation to a magnetic field. That’s at the heart of ion drives. But certain atoms are better suited for this. NASA’s ion drives typically use xenon, an inert gas, because there’s no risk of explosion.

In an ion drive, the xenon isn’t a fuel. It isn’t combusted, and it has no inherent properties that make it useful as a fuel. The energy source for an ion drive has to come from somewhere else. This source can be electricity from solar cells, or electricity generated from decay heat from a nuclear material.
Ions are created by bombarding the xenon gas with high energy electrons. Once charged, these ions are drawn through a pair of electrostatic grids—called lenses—by their charges, and are expelled out of the chamber, producing thrust. This discharge is called the ion beam, and it is again injected with electrons, to neutralize its charge. Here’s a short video showing how ion drives work:
Unlike a traditional chemical rocket, where its thrust is limited by how much fuel it can carry and burn, the thrust generated by an ion drive is only limited by the strength of its electrical source. The amount of propellant a craft can carry, in this case xenon, is a secondary concern. NASA’s Dawn spacecraft used only 10 ounces of xenon propellant—that’s less than a soda can—for 27 hours of operation.

In theory, there is no limit to the strength of the electrical source powering the drive, and work is being done to develop even more powerful ion thrusters than we currently have. In 2012, NASA’s Evolutionary Xenon Thruster (NEXT) operated at 7000w for over 43,000 hours, in comparison to the ion drive on DS1 that used only 2100w. NEXT, and designs that will surpass it in the future, will allow spacecraft to go on extended missions to multiple asteroids, comets, the outer planets, and their moons.
Missions using ion propulsion include NASA’s Dawn mission, the Japanese Hayabusa mission to asteroid 25143 Itokawa, and the upcoming ESA missions Bepicolombo, which will head to Mercury in 2017, and LISA Pathfinder, which will study low frequency gravitational waves.
With the constant improvement in ion propulsion systems, this list will only grow.

The International Space Station (ISS) achieved 15 years of a continuous human presence in orbit, as of today, Nov. 2, aboard the football field sized research laboratory ever since the first Russian/American crew of three cosmonauts and astronauts comprising Expedition 1 arrived in a Soyuz capsule at the then much tinier infant orbiting complex on Nov. 2, 2000.
Today, the space station is host to the Expedition 45 crew of six humans – from America, Russia and Japan – that very symbolically also includes the first ever crew spending one year aboard and that highlights the outposts expanding role from a research lab to a deep space exploration test bed for experiments and technologies required for sending humans on interplanetary journeys to the Martian system in the 2030s.
The ISS was only made possible by over two decades of peaceful and friendly international cooperation by the most powerful nations on Earth on a scale rarely seen.
“I believe the International Space Station should be considered for the Nobel Peace Prize,” said NASA Administrator Charles Bolden last week during remarks to the Center for American Progress in Washington, DC., on October 28, 2015.
“Exploration has taught us more than we have ever known about our Universe and our place in it.”
“The ISS has already taught us what’s possible when tens of thousands of people across 15 countries collaborate so that human beings from different nations can live and work in space together.”
“Yet, for all these accomplishments, when you consider all the possibilities ahead of us you can only reach one conclusion; We are just getting started!”

“No better place to celebrate #15YearsOnStation! #HappyBday, @space_station! Thanks for the hospitality! #YearInSpace.” tweeted NASA astronaut Scott Kelly from the ISS today along with a crew portrait.
The space station is the largest engineering and construction project in space combining the funding, hardware, knowhow, talents and crews from 5 space agencies and 15 countries – NASA, Roscomos, ESA (European Space Agency), JAXA (Japan Aerospace and Exploration Agency) and CSA (Canadian Space Agency).

The collaborative work in space has transcended our differences here on Earth and points the way forward to an optimistic future that benefits all humanity.
The station orbits at an altitude of about 250 miles (400 kilometers) above Earth. It measures 357 feet (109 meters) end-to-end and has an internal pressurized volume of 32,333 cubic feet, equivalent to that of a Boeing 747.
The uninterrupted human presence on the station all began when Expedition 1 docked at the outpost on Nov. 2, 2000, with its first residents including Commander William Shepherd of NASA and cosmonauts Sergei Krikalev and Yuri Gidzenko of Roscosmos.
For the first station trio in November 2000, the vehicle included three modules; the Zarya module and the Zvezda service module from Russia and the Unity module from the US.

Over the past 15 years, after more than 115 construction and logistics flight, the station has grown by leaps and bounds from its small initial configuration of only three pressurized modules from Russian and America into a sprawling million pound orbiting outpost sporting a habitable volume the size of a six bedroom house, with additional new modules and hardware from Europe, Japan and Canada.
The ISS has been visited by over 220 people from 17 countries.
The “1 Year ISS crew” reflects the international cooperation that made the station possible and comprises current ISS commander NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko, who are now just past the half way mark of their mission.
“Over the weekend, I called NASA astronaut Scott Kelly, who is currently halfway through his one-year mission aboard the International Space Station, to congratulate him on setting the American records for both cumulative and continuous days in space,” Bolden said in a NASA statement released today.
“I also took the opportunity to congratulate Commander Kelly — and the rest of the space station crew — for being part of a remarkable moment 5,478 days in the making: the 15th anniversary of continuous human presence aboard the space station.”

The complete Expedition 45 crew members include Station Commander Scott Kelly and Flight Engineer Kjell Lindgren of NASA, Flight Engineers Mikhail Kornienko, Oleg Kononenko and Sergey Volkov of the Russian Federal Space Agency (Roscosmos) and Flight Engineer Kimiya Yui of the Japan Aerospace Exploration Agency.
For the first nine years, the station was home to crews of two or three. Starting in 2009 the crew size was doubled to a permanent crew of six humans after the habitable volume, research facilities, equipment and supporting provisions had grown sufficiently.
“Humans have been living in space aboard the International Space Station 24-7-365 since Nov. 2, 2000. That’s 15 Thanksgivings, New Years, and holiday seasons astronauts have spent away from their families. 15 years of constant support from Mission Control Houston. And 15 years of peaceful international living in space,” says NASA.

The US contributed and built the largest number of segments of the space station, followed by Russia.
NASA’s Space Shuttles hauled the US segments aloft inside the orbiters huge payload bay, starting from the first construction mission in 1998 carrying the Unity module to the final shuttle flight STS-135 in 2011, which marked the completion of construction and retirement of the shuttles.
With the shuttle orbiters now sitting in museums and no longer flying, the Russian Soyuz capsule is the only means of transporting crews to the space station and back.
The longevity of the ISS was recently extended from 2020 to 2024 after approval from President Obama. Most of the partners nations have also agreed to the extension. Many in the space community believe the station hardware is quite resilient and hope for further extensions to 2028 and beyond.
“The International Space Station, which President Obama has extended through 2024, is a testament to the ingenuity and boundless imagination of the human spirit. The work being done on board is an essential part of NASA’s journey to Mars, which will bring American astronauts to the Red Planet in the 2030s,” says Bolden.
“For 15 years, humanity’s reach has extended beyond Earth’s atmosphere. Since 2000, human beings have been living continuously aboard the space station, where they have been working off-the-Earth for the benefit of Earth, advancing scientific knowledge, demonstrating new technologies, and making research breakthroughs that will enable long-duration human and robotic exploration into deep space.”
A key part of enabling long duration space missions to Mars is the 1 Year ISS Mission.
In coming years, additional new pressurized modules and science labs will be added by Russia and the US.
And NASA says the stations crew size will expand to seven after the US commercial Starliner and Dragon space taxis from Boeing and SpaceX start flying in 2017.
NASA is now developing the new Orion crew capsule and mammoth Space Launch System (SLS) heavy lift rocket to send astronauts to deep space destination including the Moon, asteroids and the Red Planet.
In the meantime, Kelly and his crew are also surely looking forward to the arrival of the next Orbital ATKCygnus resupply ship carrying science experiments, provisions, spare parts, food and other goodies after it blasts off from Florida on Dec. 3 – detailed in my story here.

One year after the catastrophic launch failure of Orbital ATK’s private Antares rocket seconds after liftoff with the Cygnus cargo freighter bound for the International Space Station (ISS), the firm is well on the way towards revamping the booster with modern new engines and implementing a ‘Return or Flight’ by approximately mid-2016, company officials told Universe Today. Antares is on the comeback trail.
Some 15 seconds after blastoff of the firms Antares/Cygnus rocket on October 28, 2014 on the Orb-3 resupply mission for NASA to the space station, the flight rapidly devolved into total disaster when one of the rockets first stage AJ26 engines suddenly blew up without warning after liftoff from NASA Wallops Island facility along the Eastern shore of Virginia at 6:22 p.m. ET.

“Those who are inspired by a model other than Nature, a mistress above all masters, are laboring in vain.”
-Leonardo DaVinci
What DaVinci was talking about, though it wasn’t called it at the time, was biomimicry. Biomimicry is the practice of using designs from the natural world to solve technological and engineering problems. Were he alive today, there’s no doubt that Mr. DaVinci would be a big proponent of biomimicry.
Nature is more fascinating the deeper you look into it. When we look deeply into nature, we’re peering into a laboratory that is over 3 billion years old, where solutions to problems have been implemented, tested, and revised over the course of evolution. That’s why biomimicry is so elegant: on Earth, nature has had more than 3 billion years to solve problems, the same kinds of problems we need to solve to advance in space exploration.
The more powerful our technology gets, the deeper we can see into nature. As greater detail is revealed, more tantalizing solutions to engineering problems present themselves. Scientists who look to nature for solutions to engineering and design problems are reaping the rewards, and are making headway in several areas related to space exploration.
