10 Space Science Stories to Watch in 2015

A new Avengers movie. A reboot of the Star Wars franchise. The final installment of the Hunger Games. The Martian makes it to the big screen. Yup, even if the zombie apocalypse occurs in 2015, it’ll still be a great year. But trading science fiction for fact, we’re also on track for a spectacular year in space science and exploration as well.

Humanity will get its first good look at Ceres and Pluto, giving us science writers some new pics to use instead of the same half dozen blurry dots and artist’s conceptions. SpaceX will also attempt a daring landing on a sea platform, and long duration missions aboard the International Space Station will get underway. And key technology headed to space and on Earth may lead the way to opening up the window of gravitational wave astronomy on the universe. Here’s 10 sure-fire bets to watch for in the coming year from Universe Today:

10. LISA Pathfinder

A precursor to a full-fledged gravitational wave detector in space, LISA Pathfinder will be launching atop a Vega rocket from Kourou, French Guiana in July 2015. LISA stands for the Laser Interferometer Space Antenna, and the Pathfinder mission will journey to the L1 Lagrange point between the Earth and the Sun to test key technologies. LISA Pathfinder will pave the way for the full fledged LISA space platform, a series of three free flying spacecraft proposed for launch in the 2030s.

9. AdLIGO Goes Online

And speaking of gravitational waves, we may finally get the first direct detection of the same in 2015, when Advanced LIGO is set to go online. Comprised of two L-shaped detectors, one based in Livingston Louisiana, and another in Hanford Washington, AdLIGO will feature ten times the sensitivity of the original LIGO observatory. In fact, as was the case of the hunt for the Higgs-Boson by CERN, a non-detection of gravitational waves by AdLIGO would be a much stranger result!

8. Hubble Turns 25

Launched on April 24^th, 1990 aboard the Space Shuttle Discovery, the Hubble Space Telescope celebrates 25 years in space in 2015. The final servicing mission in 2009 gave Hubble a reprieve from the space junk scrap heap, and the orbiting telescope is still going strong. Hubble has no less than pushed the limits in modern astronomy to become a modern icon of the space age.

7. The End of MESSENGER

NASA’s Mercury exploring spacecraft wraps up its mission next year. Launched in 2004, MESSENGER arrived in orbit around Mercury after a series of flybys on March 18^th, 2011. MESSENGER has mapped the innermost world in detail, and studied the space environment and geology of Mercury. In late March 2015, MESSENGER will achieve one final first, when it impacts the surface of Mercury at the end of its extended mission.

6. Akatsuki at Venus

This Japanese spacecraft missed orbital insertion a few years back, but gets a second chance at life in 2015. Launched in 2010 atop an H-IIA rocket from the Tanegashima Space Center in Japan, Akatsuki failed to enter orbit around Venus at the end of 2010, and instead headed out for a heliocentric path around the Sun. Some quick thinking by JAXA engineers led to a plan to attempt to place Akatsuki in Venusian orbit in November 2015. This would be a first for the Japanese space agency, as attempts by JAXA at placing a spacecraft in orbit around another planet – including the Mars Nozomi probe – have thus far failed.

5. SpaceX to Attempt to Land on a Sea Platform

It’ll definitely rock if they pull it off next week: on January 6^th, a SpaceX Falcon 9 rocket will lift off from Cape Canaveral with its Dragon spacecraft headed to the International Space Station on mission CRS-5. Sure, these resupply missions are becoming routine, but after liftoff, SpaceX is attempting something new and daring: landing the Falcon-9 first stage Buck Rodgers style, “fins first” on a floating barge. This is the next step in ultimately proving the feasibility of having the rocket fly back to the launch site for eventual reuse. If nothing else, expect some stunning video of the attempt soon!

4. NASA to Decide on an Asteroid Mission

Some major decisions as to the fate and the future of manned space exploration are due next year, as NASA is expected to decide on the course of action for its Asteroid Redirect Mission. The current timeline calls for the test of the SLS rocket in 2018, and the launch of a spacecraft to recover an asteroid and place it in orbit around the Moon in 2019. If all goes according to plan – a plan which could always shift with the political winds and future changes in administrations – we could see astronauts exploring a captured asteroid by the early 2020s.

3. Long Duration ISS Missions

Beginning in 2015, astronauts and cosmonauts will begin year-long stays aboard the ISS to study the effects of long duration space missions. In March of 2015, cosmonaut Mikhail Korniyenko and U.S. astronaut Scott Kelly will launch as part of Expedition 43 headed to the ISS. The Russians have conducted stays in space longer than a year aboard the Mir space station, but Kelly’s stay aboard the ISS will set a duration record for NASA astronauts. Perhaps, a simulated “Mars mission” aboard the ISS could be possible in the coming years?

2. Dawn at Ceres

Fresh off of exploring Vesta, NASA’s Dawn spacecraft will become the first mission to enter orbit around a second object, the asteroid 1 Ceres next year in April 2015. The largest asteroid and the first object of its kind discovered on the first day of the 19^th century, Ceres looks to be a fascinating world in its own right. Does it possess water ice? Active geology? Moons of its own? If Dawn’s performance at Vesta was any indication, we’re in for another exhilarating round of space exploration!

1. New Horizons at Pluto

An easy No. 1,we finally get our first good look at Pluto in July, as NASA’s New Horizons spacecraft flies less than 14,000 kilometres from the surface of the distant world. Launched in 2006, New Horizons will “thread the needle” between Pluto and Charon in a flurry of activity as it passes by. New Horizons will then turn back as it passes into the shadows of Pluto and Charon and actually view the two worlds as they occult the distant Sun. And from there, New Horizons will head out to explore Kuiper Belt Objects of opportunity.

And these are just the top stories that are slated to be big news in space in 2015. Remember, another Chelyabinsk meteor or the next big comet could drop by at any time… space news can be unpredictable, and its doubtless that 2015 will have lots more surprises in store.

Elon Musk’s Hyperloop Might Become A Reality After All

Fans of Elon Musk and high-speed transit are sure to remember the Hyperloop. Back in 2013, Musk dropped the idea into the public mind with a paper that claimed that using the right technology, a high-speed train could make the trip from San Fransisco to Los Angeles in just 35 minutes.

However, Musk also indicated that he was too busy to build such a system, but that others were free to take a crack at it. And it seems that a small startup from El Segundo, California is prepared to do just that.

That company is JumpStartFund, a startup that combines elements of crowdfunding and crowd-sourcing to make innovation happen. Dirk Ahlborn, the CEO of JumpStartFund, believes they can build Musk’s vision of a solar-powered transit system that would transport people at up to speeds of 1280 km/h (800 mph).

Together with SpaceX, JumpStartFund has created a subsidiary called Hyperloop Transportation Technologies (HTT), Inc. to oversee all the necessary components to creating the system. This included bringing together 100 engineers from all over the country who work for such giants of industry as Boeing, NASA, Yahoo!, Airbus, SpaceX, and Salesforce.

*Concept art of what a completed Hyperloop would look like amidst the countryside. Credit: HTT/JumpStartFund*

Last week, these engineers came together for the first time to get the ball rolling, and what they came up with a 76-page report (entitled “Crowdstorm”) that spelled out exactly how they planned to proceed. By their own estimates, they believe they can complete the Hyperloop in just 10 years, and at a cost of $16 billion.

A price tag like that would be sure to scare most developers away. However, Ahlborn is undeterred and believes that all obstacles, financial or otherwise, can be overcome. As he professed in an interview with Wired this week: “I have almost no doubt that once we are finished, once we know how we are going to build and it makes economical sense, that we will get the funds.”

The HTT report also covered the basic design and engineering principles that would go into the building of the train, as Musk originally proposed it. Basically, this consists of pods cars that provide their own electricity through solar power, and which are accelerated through a combination of linear induction motors and low air pressure.

Much has been made of this latter aspect of the idea, and has often compared to the kinds of pneumatic tubes that used to send messages around office buildings in the mid-20th century. But of course, what is called for with the Hyperloop is bit more sophisticated.

Basically, the Hyperloop will operate by providing each capsule with a soft air cushion to float on, avoiding direct contact with rails or the tube, while electromagnetic induction is used to speed up or slow the capsules down, depending on where they are in the transit system.

However, the HTT engineers indicated that such a system need not be limited to California. As it says in the report: “While it would of course be fantastic to have a Hyperloop between LA and SF as originally proposed, those aren’t the only two cities in the US and all over the world that would seriously benefit from the Hyperloop. Beyond the dramatic increase in speed and decrease in pollution, one of the key advantages the Hyperloop offers over existing designs for high-speed rail is the cost of construction and operations.”

The report also indicated the kind of price bracket they would be hoping to achieve. As it stands, HTT’s goal is “to keep the ticket price between LA and SF in the $20-$30 range,” with double that amount for return tickets. But with an overall price tag of $16 billion, the report also makes allowances for going higher: “[Our] current projected cost is closer to $16 billion,” they claim, “implying a need for a higher ticket price, unless the loop transports significantly more than 7.4 million annually, or the timeline for repayment is extended.”

In addition, the report also indicates that they are still relying heavily on Musk’s alpha document for much of their cost assessment. As a result, they can’t be specific on pricing or what kinds of revenues the Hyperloop can be expected to generate once its up and running.

Also, there’s still plenty of logistical issues that need to be worked out, not to mention the hurdles of zoning, local politics and environmental assessments. Basically, HTT can look forward to countless challenges before they even begin to break ground. And since they are depending on crowdfunding to raise the necessary funds, it is not even certain whether or not they will be able to meet the burden of paying for it.

However, both Ahlborn and the HTT engineering team remain optimistic. Ahlborn believes the financial hurdles will be overcome, and if there was one thing that came through in the team’s report, it was the belief that something like the Hyperloop needs to happen in the near future. As the team wrote in the opening section of “Crowdstorm”:

“It quickly becomes apparent just how dramatically the Hyperloop could change transportation, road congestion and minimize the carbon footprint globally. Even without naming any specific cities, it’s apparent that the Hyperloop would greatly increase the range of options available to those who want to continue working where they do, but don’t wish to live in the same city, or who want to live further away without an unrealistic commute time; solving some of the major housing issues some metropolitan areas are struggling with.”

Only time will tell if the Hyperloop will become the “fifth mode of transportation” (as Musk referred to it initially) or just a pipe-dream. But when it was first proposed, it was clear that what the Hyperloop really needed was someone who believed in it and enough money to get it off the ground. As of now, it has the former. One can only hope the rest works itself out with time.

Successful Engine Test Enables SpaceX Falcon 9 Soar to Space Station in Jan. 2015

KENNEDY SPACE CENTER, FL – To ensure the highest possibility of success for the launch of a critical resupply mission to the International Space Station (ISS), SpaceX has announced the successful completion of a second static fire test of the first stage propulsion system of the firms commercial Falcon 9 rocket on Dec. 19.

The successful engine test clears the path towards a liftoff now rescheduled to early January 2015.

The launch of the Falcon 9 had been slated for Dec. 19, but NASA and SpaceX decided just 1 day before liftoff on Dec. 18 to postpone the launch of the CRS-5 resupply mission into the new year, when the first static fire test failed to run for its full duration of approximately three seconds.

“SpaceX completed a successful static fire test of the Falcon 9 rocket [on Dec. 19] in advance of the CRS-5 mission for NASA,” said SpaceX in a statement.

The second test was done because the first test of the Merlin 1D engines did not run for its full duration of about three seconds.

“While the Dec. 17 static fire test accomplished nearly all of our goals, the test did not run the full duration, ”SpaceX spokesman John Taylor confirmed to Universe Today.

“The data suggests we could push forward without a second attempt, but out of an abundance of caution, we are opting to execute a second static fire test prior to launch.”

Both tests were conducted at Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

“We opted to execute a second test,” noted SpaceX.

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter had been slated to liftoff on Dec. 19 on its next unmanned cargo run dubbed CRS-5 to the ISS under NASA’s Commercial Resupply Services (CRS) contract.

Following the catastrophic failure of the Orbital Sciences Antares rocket and Cygnus cargo freighter on Oct 28 from NASA’s Wallops Flight Facility in Virginia, officials are being prudently cautious to ensure that all measures are being carefully rechecked to maximize the possibilities of a launch success.

The new launch date for CRS-5 is now set for no earlier than Jan. 6, 2015

“Given the extra time needed for data review and testing, coupled with the limited launch date availability due to the holidays and other restrictions, our earliest launch opportunity is now January 6 with January 7 as a backup,” said SpaceX.

The unmanned cargo freighter is loaded with more than 3,700 pounds of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear.

The Dragon research experiments will support over 256 science and research investigations for the six person space station crews on Expeditions 42 and 43.

CRS-5 marks the company’s fifth resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016.

Among the other mission goals, SpaceX is planning a daring and bold attempt to propulsively land and recover the first stage on an ocean going platform called the “autonomous spaceport drone ship.”

KENNEDY SPACE CENTER, FL – Due to technical problems encountered during a hot fire test of the first stage engines this week with the SpaceX Falcon 9 rocket, the planned Dec. 19 launch of the commercial rocket and NASA contracted Dragon cargo freighter to the International Space Station (ISS) on a critical resupply mission has been postponed a few weeks into the new year to Jan. 6 at the earliest “out of an abundance of caution,” SpaceX officials told Universe Today.

Prior to every launch, SpaceX performs an internally required full countdown dress rehearsal and hot fire test of the first stage propulsion systems.

The hot fire test attempted on Tuesday “did not run for its full duration” of about three seconds, SpaceX spokesman John Taylor confirmed to me.

Therefore SpaceX and NASA managers decided to postpone the launch in order to run another static fire test.

“We are opting to execute a second static fire test prior to launch,” Taylor said.

In light of the catastrophic failure of the Orbital Sciences Antares rocket and Cygnus cargo freighter, everything must be done to ensure a launch success.

Due to the large amount of work required to test and analyze all rocket systems and the impending Christmas holidays, the earliest opportunity to launch is Jan. 6.

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter had been slated to liftoff on its next unmanned cargo run dubbed CRS-5 to the ISS under NASA’s Commercial Resupply Services (CRS) contract.

Here is the full update from SpaceX.

“While the recent static fire test accomplished nearly all of our goals, the test did not run the full duration. The data suggests we could push forward without a second attempt, but out of an abundance of caution, we are opting to execute a second static fire test prior to launch.”

“The ISS orbits through a high beta angle period a few times a year. This is where the angle between the ISS orbital plane and the sun is high, resulting in the ISS’ being in almost constant sunlight for a 10 day period.

“During this time, there are thermal and operational constraints that prohibit Dragon from being allowed to berth with the ISS. This high beta period runs from 12/28/14-1/7/15”

“Note that for a launch on 1/6 , Dragon berths on 1/8.”

“Both Falcon 9 and Dragon remain in good health, and our teams are looking forward to launch just after the New Year.”

SpaceX Falcon 9 Rocket to Attempt Daring Ocean Platform Landing with Next Launch

KENNEDY SPACE CENTER, FL – In a key test of rocket reusability, SpaceX will attempt a daring landing of their Falcon 9 first stage rocket on an ocean platform known as the “autonomous spaceport drone ship” following the planned Friday, Dec. 19, blastoff on a high stakes mission to the International Space Station (ISS).

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter is slated to liftoff on its next unmanned cargo run, dubbed CRS-5, to the ISS under NASA’s Commercial Resupply Services (CRS) contract. In a late development, there is a possibility the launch could be postponed to January 2015.

The instantaneous launch window for the Falcon 9/Dragon is slated for 1:20 p.m from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

As the Dragon proceeds to orbit, SpaceX engineers will attempt to recover the Falcon 9 first stage via a precision landing for the first time “on a custom-built ocean platform known as the autonomous spaceport drone ship,” according to a SpaceX statement.

“While SpaceX has already demonstrated two successful soft water landings, executing a precision landing on an unanchored ocean platform is significantly more challenging.”

SpaceX rates the chances of success at “perhaps 50% at best.”

Of course since this has never been attempted before, tons of planning is involved and lots can go wrong.

But this is space exploration, and it’s not for the meek and mild.

It’s time to go boldly where no one has gone before and expand the envelope if we hope to achieve great things.

The 14 story Falcon 9 will be zooming upwards at 1300 m/s (nearly 1 mi/s). Engineers will then relight the Merlin 1D first stage engines to stabilize and lower the rocket.

Four hypersonic grid fins had been added to the first stage and placed in an X-wing configuration. They will be deployed only during the reentry attempt and will be used to roll, pitch, and yaw the rocket in concert with gimballing of the engines.

Here’s a description from SpaceX:

“To help stabilize the stage and to reduce its speed, SpaceX relights the engines for a series of three burns. The first burn—the boostback burn—adjusts the impact point of the vehicle and is followed by the supersonic retro propulsion burn that, along with the drag of the atmosphere, slows the vehicle’s speed from 1300 m/s to about 250 m/s. The final burn is the landing burn, during which the legs deploy and the vehicle’s speed is further.”

“To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, we’re targeting a landing accuracy of within 10 meters.”

SpaceX Continues to Expand Facilities, Workforce in Quest for Space

SpaceX was founded by Elon Musk in 2002 with a dream of making commercial space exploration a reality. Since that time, Musk has seen his company become a major player in the aerospace industry, landing contracts with various governments, NASA, and other private space companies to put satellites in orbit and ferry supplies to the International Space Station.

But 2014 was undoubtedly their most lucrative year to date. In September, the company (along with Boeing) signed a contract with NASA for $6.8 billion to develop space vehicles that would bring astronauts to and from the ISS by 2017 and end the nation’s reliance on Russia.

And this past week, the company announced a plan to expand operations at its Rocket Development and Test Facility in McGregor, Texas. This move, which is costing the company a cool $46 million, is expected to create 300 new full-time jobs in the community and expand testing and development even further.

According to Mike Copeland of the Waco Tribute, an additional $1.5 million in funding could be allocated from McLennon County. This would give SpaceX a total of $3 million in funds from the Waco-McLennan County Economic Development Corportation, a fund which is used to attract and keep industry in the region.

Copeland also indicates that a report prepared by the Waco City Council specified what types of jobs would be created. Apparently, SpaceX is is need of additional engineers, technicians and industry professionals. No doubt, this planned expansion has much to do with the company meeting its new contractual obligations with NASA.

Originally built in 2003, the Rocket Development and Test Facility has been the site of some exciting events over the years. Using rocket test stands, the company has conducted several low-altitude Vertical Takeoff and Vertical Landing (VTVL) test flights with the Falcon 9 Grasshopper rocket. In addition, the McGregor facility is used for post-flight disassembly and defueling of the Dragon spacecraft.

In the past ten years, SpaceX has also made numerous expansions and improvements to the facility, effectively doubling the size of the facility by purchasing several pieces of adjacent farmland. As of September 2013, the facility measured 900 acres (360 hectares). But by early 2014, the company had more than quadrupled its lease in McGregor, to a total of 4,280 acres.

Though far removed from the company’s rocket building facilities at their headquarters in Hawthorne, California, the facility plays an important role in the development of their space capsule and reusable rocket systems. According to SpaceX’s company website, “Every Merlin engine that powers the Falcon 9 rocket and every Draco thruster that controls the Dragon spacecraft is tested on one of 11 test stands.”

*A Falcon 9 Grasshopper conducting VTVL testing. Credit: SpaceX*

In short, the facility is the key testing grounds for all SpaceX technology. And now that the company is actively collaborating with NASA to restore indigenous space-launch ability to the US, more testing will be needed. Much has been made about the company’s efforts with VTVL rocket systems – such as the Falcon 9 Grasshopper (pictured above) – but the Dragon V2 takes things to another level.

As revealed by SpaceX in May of this year, the Dragon V2 capsule is designed to ferry crew members and supplies into orbit, and then land propulsively (i.e. under its own power) back to Earth before refueling and flying again. This is made possible thanks to the addition of eight side-mounted SuperDraco engines.

Compared to the standard Draco Engine, which is designed to give the Dragon Capsule (and the upper stages of the Falcon 9 rocket) attitude control in space, the SuperDraco is 100 times more powerful.

According to SpaceX, each SuperDraco is capable of producing 16,000 pounds of thrust and can be restarted multiple times if necessary. In addition, the engines have the ability to deep throttle, providing astronauts with precise control and enormous power.

With eight engines in total, that would provide a Dragon V2 with 120,000 pounds of axial thrust, giving it the ability to land anywhere without the need of a parachute (though they do come equipped with a backup chute).

Between this and ongoing developments with the Falcon 9 reusable rocket system, employees in McGregor are likely to have their hands full in the coming years. The expansion is expected to be complete by 2018.

NASA and SpaceX targeting Dec. 19 for next Space Station Launch

NASA and SpaceX are now targeting Dec. 19 as the launch date for the next unmanned cargo run to the International Space Station (ISS) under NASA’s Commercial Resupply Services contract.

The fifth SpaceX cargo mission was postponed from Dec. 16 to Dec. 19 to “allow SpaceX to take extra time to ensure they do everything possible on the ground to prepare for a successful launch,” according to a statement from NASA.

The Dragon spacecraft will launch atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Both the Falcon 9 rocket and its Dragon spacecraft are in good health, according to NASA.

The mission dubbed SpaceX CRS-5 is slated for liftoff at 1:20 p.m.

An on time liftoff will result in a rendezvous with the ISS on Sunday. The crew would grapple the Dragon with the stations 57 foot long robotic arm at about 6 a.m.

US astronaut and station commander Barry Wilmore will operate the Canadarm2 to capture the SpaceX Dragon when it arrives Sunday morning. ESA astronaut Samantha Cristoforetti will assist Wilmore working at a robotics workstation inside the domed Cupola module during the commercial craft’s approach and rendezvous.

The unmanned cargo freighter is loaded with more than 3,700 pounds of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear.

The Dragon research experiments will support over 256 science and research investigations for the six person space station crews on Expeditions 42 and 43.

Among the payloads is the Cloud-Aerosol Transport System (CATS), a remote-sensing laser instrument to measure clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere.

A secondary objective of SpaceX is to attempt to recover the Falcon 9 first stage on an off shore barge.

The SpaceX CRS-4 mission to the ISS concluded with a successful splashdown on Oct 25 after a month long stay.

The SpaceX CRS-5 launch is the first cargo launch to the ISS since the doomed Orbital Sciences Antares/Cygnus launch ended in catastrophe on Oct. 28.

With Antares launches on indefinite hold, the US supply train to the ISS is now wholly dependent on SpaceX.

Orbital Sciences has now contracted United Launch Alliance (ULA) to launch the firms Cygnus cargo freighter to the ISS by late 2015 on an Atlas V rocket.

A History of Launch Failures: “Not Because They are Easy, but Because They are Hard”

The Rice Speech words hold especially true when the NASA's goals seem challenged and suddenly not so close at hand. (Photo Credit: NASA)

Over the 50-plus years since President John F. Kennedy’s Rice University speech, spaceflight has proven to be hard. It doesn’t take much to wreck a good day to fly.

Befitting a Halloween story, rocket launches, orbital insertions, and landings are what make for sleepless nights. These make-or-break events of space missions can be things that go bump in the night: sometimes you get second chances and sometimes not. Here’s a look at some of the past mission failures that occurred at launch. Consider this a first installment in an ongoing series of articles – “Not Because They Are Easy.”

The evening of October 28, 2014, was another of those hard moments in the quest to explore and expand humanity’s presence in space. Ten years ago, Orbital Sciences Corporation sought an engine to fit performance requirements for a new launch vehicle. Their choice was a Soviet-era liquid fuel engine, one considered cost-effective, meeting requirements, and proving good margins for performance and safety. The failure of the Antares rocket this week could be due to a flaw in the AJ-26 or it could be from a myriad of other rocket parts. Was it decisions inside NASA that cancelled or delayed engine development programs and led OSC and Lockheed-Martin to choose “made in Russia” rather than America?

Here are other unmanned launch failures of the past 25 years:

Falcon 1, Flight 2, March 21, 2007. Fairings are hard. There are fairings that surround the upper stage engines and a fairing covering payloads. Fairings must not only separate but also not cause collateral damage. The second flight of the Falcon 1 is an example of a 1st stage separation and fairing that swiped the second stage nozzle. Later, overcompensation by the control system traceable to the staging led to loss of attitude control; however, the launch achieved most of its goals and the mission was considered a success.

Proton M Launch, Baikonur Aerodrome, July 2, 2013. The Proton M is the Russian Space program’s workhorse for unmanned payloads. On this day, the Navigation, Guidance, and Control System failed moments after launch. Angular velocity sensors of the guidance control system were installed backwards. Fortunately, the Proton M veered away from its launch pad sparing it damage.

Ariane V Maiden Flight, June 4, 1996. The Ariane V was carrying an ambitious ESA mission called Cluster – a set of four satellites to fly in tetrahedral formation to study dynamic phenomena in the Earth’s magnetosphere. The ESA launch vehicle reused flight software from the successful Ariane IV. Due to differences in the flight path of the Ariane V, data processing led to a data overflow – a 64 floating point variable overflowing a 16 bit integer. The fault remained undetected and flight control reacted in error. The vehicle veered off-course, the structure was stressed and disintegrated 37 seconds into flight. Fallout from the explosion caused scientists and engineers to don protective gas masks. (View: 0:50)

Delta II, January 17, 1997. The Delta II is one of the most successful rockets in the history of space flight, but not on this day. Varied configurations change up the number of solid rocket motors strapped to the first stage. The US Air Force satellite GPS IIR-1 was to be lifted to Earth orbit, but a Castor 4A solid rocket booster failed seconds after launch. A hairline fracture in the rocket casing was the fault. Both unspent liquid and solid fuel rained down on the Cape, destroying launch equipment, buildings, and even parked automobiles. This is one of the most well documented launch failures in history.

Compilation of Early Launch Failures. Beginning with several of the early failures of Von Braun’s V2, this video compiles many failures over a 70 year period. The early US space program endured multiple launch failures as they worked at a breakneck speed to catch up with the Soviets after Sputnik. NASA did not yet exist. The Air Force and Army had competing designs, and it was the Army with the German rocket scientists, including Von Braun, that launched the Juno 1 rocket carrying Explorer 1 on January 31, 1958.

One must always realize that while spectacular to launch viewers, a rocket launch has involved years of development, lessons learned, and multiple revisions. The payloads carried involve many hundreds of thousands of work-hours. Launch vehicle and payloads become quite personal. NASA and ESA have offered grief counseling to their engineers after failures.

“We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.”

Getting to the International Space Station is no easy task. Generally speaking, it involves loading up a space capsule with several tons of cargo and then expending millions of liters of fuel to get it into orbit. This process is time consuming and very expensive. And what if astronauts want to send some things back? Currently, their only option for return capability is provided by the same cargo capsules that are sent up to them.

NASA WALLOPS FLIGHT FACILITY, VA – An Orbital Sciences Corp. commercial Antares rocket was given the GO for its first night launch on Oct. 27, following a launch readiness review on Sunday, Oct. 26, between managers from Orbital Sciences Corp. of Dulles, Virginia, and NASA.

The rocket was rolled to the launch pad and erected. Technicians are putting the final touches on the rocket to prepare it for flight to the International Space Station (ISS).

NASA and Orbital Sciences are targeting Antares for blastoff at 6:45 p.m. EDT on Oct. 27 from beachside Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island Flight Facility on Virginia’s eastern shore.

There is a 10 minute launch window to get Antares off the ground as the launch pad moves into the plane of the space stations orbit. The slightly longer launch window is due to the extra thrust available from using a new, more powerful ATK built upper stage engine.

The rare spectacle of a night launch within view of tens of millions could WOW hordes of US East Coast residents in densely populated areas up and down the Atlantic shoreline – weather permitting.

The current forecast calls for an almost unheard of 98% chance of favorable weather conditions at launch time.

Depending on local weather conditions, the Antares blastoff will be visible along much of the US eastern seaboard – stretching from Maine to South Carolina.

Orbital 3 Launch from NASA Wallops Island, VA on Oct. 27, 2014- Time of First Sighting Map. This map shows the rough time at which you can first expect to see Antares after it is launched on Oct. 27, 2014. It represents the time at which the rocket will reach 5 degrees above the horizon and varies depending on your location . We have selected 5 degrees as it is unlikely that you'll be able to view the rocket when it is below 5 degrees due to buildings, vegetation, and other terrain features. However, depending on your local conditions the actual time you see the rocket may be earlier or later. As an example, using this map when observing from Washington, DC shows that Antares will reach 5 degrees above the horizon approximately 117 seconds after launch (L + 117 sec).

Antares is carrying Orbital’s privately developed Cygnus pressurized cargo freighter loaded with nearly 5000 pounds (2200 kg) of science experiments, research instruments, crew provisions, spare parts, spacewalk and computer equipment and gear on a critical resupply mission dubbed Orb-3 bound for the International Space Station (ISS).

This is the heaviest cargo load yet lofted by a Cygnus. Some 800 pounds additional cargo is loaded on board compared to earlier flights, that’s enabled by using the more powerful ATK CASTOR 30XL second stage for the first time.

Research gear and experiments account for about 1600 pounds (720 kg), or about one third of Cygnus total cargo load.

Among the items aboard are 32 cubesats and deployers, a 6000 psi high pressure replacement nitrogen tank needed for spacewalks from the Quest airlock, experiments enabling the first space-based observations of meteors entering Earth’s atmosphere, determination of how blood flows from the brain to the heart in the absence of gravity, investigations on the impact of space travel on both the human immune system and an individual’s microbiome, the collection of microbes that live in and on the human body, and student science investigations from the SSEP/NCESSE.

“There is nothing more exciting than spaceflight,” said Frank Culbertson, Orbital’s executive vice president of the advanced programs group, at a pre-launch briefing at NASA Wallops.

“It is important to inspire the next generation of scientists. We need to keep the kids inspired to study math and science and keep going back to space. If we stop going to space, it will be very hard to restart.”

This Cygnus resupply module, dubbed “SS Deke Slayton,” honors one of America’s original Mercury 7 astronauts, Donald “Deke” K. Slayton. He flew on the Apollo-Soyuz Test Project mission in 1975 and championed commercial space endeavors after retiring from NASA in 1982. Slayton passed away in 1993.

The Orbital-3, or Orb-3, mission is the third of eight cargo resupply missions to the ISS through 2016 under the NASA Commercial Resupply Services (CRS) contract award valued at $1.9 Billion.

Orbital Sciences is under contract to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware for the eight ISS flight.

NASA Television will broadcast live coverage of the launch, including pre- and post-launch briefings and arrival at the station. Launch coverage begins at 5:45 p.m. EDT.

NASA will broadcast the Antares launch live on NASA TV starting at 5:45 p.m. Monday – http://www.nasa.gov/nasatv

You can also watch the pre- and post launch briefings on Monday on NASA TV.

Of course the absolute best viewing will be locally in the mid-Atlantic region closest to Wallops Island.

Locally at Wallops you’ll get a magnificent view and hear the rockets thunder at the NASA Wallops Visitor Center or other local spots around the Chincoteague National Wildlife Refuge area.
