SpaceX Dragon Launches from Apollo Pad to Resupply Space Station

A SpaceX Dragon capsule has successfully launched atop a Falcon 9 rocket from the historic Launch Complex 39A at the Kennedy Space Center on a mission to resupply the International Space Station.

From the same launchpad used to send men to the Moon during the Apollo missions, the Commercial Resupply Services(CRS)-10 mission blasted off at 9:39 a.m. Eastern Time bound for the orbiting laboratory.

Today's events mark the first time a rocket has roared to life at Pad 39A since the final flight of the space shuttle programme in July 2011.

Just eight minutes after launch, the rocket's expended first stage fell back to Earth, fired its engines, before successfully landing upright for the second time at SpaceX's Landing Zone-1 -  around 15 kilometers south of Launch Complex 39.

The vehicle will arrive at the space station on early on Monday, February 22 carrying science research, crew supplies and hardware to the orbiting laboratory in support of the Expedition 50 and 51 crews.

Among the investigations are experiments with potential to fight human disease and a new autonomous spacecraft docking technology for testing.

From the station's Cupola, NASA astronaut Shane Kimbrough alongside European Space Agency astronaut Thomas Pesquet will capture Dragon with the station's robotic arm, Canadarm-2(Grapple is scheduled at 6 a.m.) before flight controllers in Mission Control in Houston berth Dragon to the Earth-facing port of the station's Harmony module a few hours later.

Today's launch marks the beginning of the tenth Dragon resupply ship to fly to the International Space Station and the first commercial flight from Pad-39A.

Dragon was originally scheduled to launch a day earlier on February 18, but a problem with the positioning of the vehicle's second stage engine nozzle led to an abort at T-13 seconds.

Just two days after Dragon's arrival to the station, the Russian Progress 66 resupply craft will launch from the Baikonur Cosmodrome in Kazakhstan at 12:58 a.m. EST on February 22 to deliver food, fuel and supplies to the International Space Station, followed by manual docking on Friday morning.

Space - A Cosmic Ocean Elon Musk Intends to Sail

Speaking in front of a capacity crowd at the 67th International Astronomical Congress in Guadalajara, Mexico, SpaceX founder, CEO and chief designer, Elon Musk, boldly unveiled his futuristic plans for sending humans to Mars.

In his much anticipated speech entitled "Making Humans a Multiplanetary Spacies," the billionaire outlined his ideas for colonizing the red planet in his trademark thinking-out-loud style of speaking.

Congress on September 27. credit: bloomberg.com

He began by asking the question, "Why Mars?", before explaining that solar system real-estate is limited and that finding a prime spot is not as easy as people may think.

Musk stated that if a manned launch to Mars were to take place right now, a seat on board that ship would cost an astronomical $10bn per person. In other words, the system does not yet exist.

However, Musk's mantra has and always will revolve around driving down the cost of getting to space and making it accessible to all.

"The cost of a Mars ticket should equal the median cost of a house in the United States.. which is about $200,000" he went on to say. "You can't create a self-sustaining civilisation on Mars if the price is ten billion dollars per person."

This Musk explained, could only be achieved by addressing four key issues. These issues are:

-Full reusability
-Refilling in orbit
-Propellant filling on Mars
-Using the right propellant

If he succeeds in doing so, Musk believes he will be able to reduce the cost per tonne to Mars by five million percent, and in the process, facilitating the mass landing of around a million or so humans on our nearest neighbour by the 2060s.

While proclamations of slashing ticket prices to Mars were greeted with enthusiastic whoops and hollers from the crowd, the question that everyone wanted answered, was what exactly will this interplanetary space system look like?

Standing in front of a fifteen-foot-tall image of Mars, occasionally Musk would turn to catch a subtle glimpse of the revolving red globe, as if to remind himself that Mars was still there - that it wasn't so far away.

Getting to Mars
Blasting off atop a 254-foot booster from the same launch used on man's first voyage to land a man on the Moon, SpaceX's "Planetary Spaceship"(yet to be officially named, but Musk admitted that he would probably name the first ship "Heart of Gold" as a tribute to the ship used in "The Hitchhikers Guide to the Galaxy") would firstly be delivered into a preliminary parking orbit around the Earth.

The booster, similar in profile of returning a Falcon-9 first stage to Earth, would then return directly to the launchpad, refuel its tanker, and launch back up to the parked manned vehicle in orbit.

This refueling process would be repeated four more times before the interplanetary ship would get the green light to rendezvous with the red planet.


In what he described as something straight out of Battlestar Galactica, Musk said he hopes to include not one, not two, but a thousand Mars ships in a single fleet, with up to two hundred people per spacecraft.

The Planetary Spaceship will use its aerodynamic lift ability to enter the Martian atmosphere, and will come to a soft landing on the surface of the planet using its propulsive rocket system.

In theory, this would allow the Spaceship to land on any rocky body in the solar system, and provided there would be fueling stations along the way, it would result in humans gaining access to almost anywhere in the solar system.

The people in these craft would require only "a few days of training" before being certified to fly. If you arrive at the place and decide you don't like it as much as you thought and yearn to come home - don't worry! With the billionaire planning on sending fleets to Mars roughly every two years, there'll be another ship along shortly to bring you back to mother Earth.

As far as safety is concerned, for the first flights of the Interplanetary Spaceship on a journey to Mars, Musk offered the grim prediction that "The risk of fatality will be high."

Throughout the speech, Musk shied away from setting any concrete dates for accomplishing the above goals, estimating that it will take anywhere between forty and one hundred years to develop a self-sustaining species from the first ship's rendezvous.

What happens now?
As a space enthusiast, Musk excites me with his audacious plans to turn humans into a multiplanetary species. The fact that someone is even thinking about doing so, let alone already investing tens of millions of dollars in order to make it a reality brings me a profound sense of joy for the present, and quiet optimism for the future.

"With each passing day, the barrier separating science fiction
and science fact is constantly being eroded"

Scouring online forums, websites and fan pages in the hours after Musk delivered his keynote, reactions ranged from sheer delight to downright doom and gloom. If Musk's speech was a movie, it would have received mixed reviews, and here's why..

Following the catastrophic loss of two of his Falcon-9 booster's in just fifteen months(for which a smoking gun in the second accident is yet to be identified), SpaceX's reputation as a reliable company capable of delivering payloads and one day astronauts in to space has taken a hard blow.

By the beginning of 2018 Musk hopes to begin conducting missions of its Red Dragon spacecraft(the vehicle that will deliver SpaceX's first astronauts to Mars), with Mars flights set to commence before 2023.

However, with the Hawthorne company yet to deliver a single astronaut to the International Space Station in its Crew Dragon, Elon Musk's timelines for the moment must be taken with a pinch of salt.

In summary, let us recognise that space is an awfully big ocean, and getting comfortable in the shallow cosmic waters of low-Earth orbit is a must before even thinking about venturing any deeper. It is therefore essential that Musk invest as much time and money into figuring what is going wrong with the Falcon-9, before pressing on with bigger issues.

With each passing day, the barrier separating science fiction and science fact is constantly being eroded. But it is mandatory that Musk firstly learns how to fly his troublesome Falcon as close to total reliability as possible. Otherwise, none of this will ever get off the ground - let alone to Mars.

Godspeed, Elon Musk!

SpaceX Dragon Returns to International Space Station

The SpaceX Dragon cargo vehicle has arrived at the International Space Station on its eighth flight to resupply the orbiting complex.

The Commercial Resupply Services(CRS)-8 was captured by ESA astronaut Tim Peake using the station's robotic arm, Canadarm2. Capture was confirmed to have taken place at 7:23 a.m. Eastern Time as the station flew 250 miles over the Pacific Ocean.

Shortly after grapple, the Expedition 47 Flight Engineer informed teams of flight controllers in Mission Control in Houston and in SpaceX Headquarters in Hawthorne California of his success;

"Looks like we've captured a Dragon" 

Two hours later at 9:57 a.m. robotic operators in Mission Control in Houston slowly berthed the vehicle to the Earth-facing port of the station's Harmony module.

Today's arrival is an historic one, as it marks the first time that two commercially-built cargo vehicles will be docked to the International Space Station simultaneously. Orbital ATK's Cygnus cargo craft is currently bolted to the Unity module of the ISS having arrived on March 26.

It also marks only the second time in the history of the International Space Station programme that six visiting vehicles have been docked to the station at once.

Dragon, making its Return to Flight to the ISS following a catastrophic launch anomaly in June 2015, launched atop a Falcon 9 rocket at 9:43 p.m. Eastern Time on Friday April 8 from Cape Canaveral carrying 6,900 pounds/3,130 kilograms worth of science research, crew supplies and hardware to the orbiting laboratory in support of the Expedition 47 and 48 crews.

Just minutes after first stage separation, the rocket's first stage fell back to Earth, fired its thrusters and deployed its landing legs before successfully landing upright for the first time on a barge at sea. Friday's activities marked the second time that Elon Musk's company has accomplished such a feat - the first coming back on December 21.

Today's arrival will bring to an end the recent period of busy traffic to and from the International Space Station. CRS-8 is the fourth visiting vehicle to visit the laboratory in as many weeks, following the arrival of the Soyuz TMA-20M, Cygnus CRS OA-6 and the Progress 63P.

On April 15, robotic operators will once again take control of Canadarm2 and remove the much anticipated Bigelow Expandable Activity Module(BEAM), and berth it to the aft port of the station's Tranquility module.


Bigelow Expandable Activity Module(BEAM)


BEAM is an expandable habitat built by Bigelow Aerospace that will remain on station for a period of two years. NASA and its partners are currently investigating the practicalities of using expandable habitats in the near-Earth environment as well as on future missions to the Moon or Mars.

This will be the first time an expandable habitat will be docked to the station, so the procedure will take some time, allowing teams to closely observe the expansion process as well as the safety of the crew and the station. During this time the module will expand from its packed dimensions of 7.75 feet in diameter and 5.7 feet long, to its pressurised size of 10,5 feet in diameter and 12 feet long.

The expandable module is made up of soft fabrics instead of metal which allows the habitat to be packed to a small volume during launch and later expanded to its full size in space. Two radiation sensors, temperature and micrometeorite impacts inside BEAM will help scientists and engineers to better understand thermal, radiation and long-term leak performance of expandable habitats.

The habitat will be inflated by the crew at the end of May and it is expected that crew members will enter BEAM twice or three times per six month increment to swap out sensors that need to be returned to Earth for analysis.

SpaceX Dragon Lost Just Minutes After Launch to Space Station

The SpaceX Dragon cargo vehicle making its seventh resupply mission to the International Space Station has been lost just minutes after launching from the Cape Canaveral Air Force Station in Florida. The rocket and vehicle have both been lost.

The Falcon 9 appeared to have exploded just after the separation of the rocket's first stage. All data with the vehicle was lost, two minutes and nineteen seconds into the flight.

It is currently unclear what exactly caused today's failure. According the Pam Anderson of SpaceX there were no problems with the performance of the first stage of the Falcon 9, and telemetry with Dragon was received by teams on the ground shortly after the incident occurred.

SpaceX founder Elon Musk said on Twitter; "There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause."

ISS programme managers have assured the public that anomalies such as the one which happened today are planned for and as a result, it is estimated that the crew currently has enough supplies to last until late October.

Some of the cargo which was being flown aboard Dragon includes a number of student experiments, plant growth experiments, a space suit as well as provisions for the crew on board the station.

Another item also lost today was the International Docking Adapter-1(IDA-1) which was due to be installed on the Pressurised Mating Adapter located on the forward facing port of the Harmony. This would allow commercial crew vehicles built by Boeing and SpaceX to dock with the station thus allowing them to transport astronauts from the United States to the International Space Station. The first flight of Commercial Crew are slated to occur no later than 2017.

This is the third space station resupply ship that has been lost in the past eight months. Today's anomaly occurred exactly two months after a Russian Progress resupply ship spun out of control and burned up in the Earth's atmosphere several days later. An Orbital Sciences Cygnus cargo craft exploded shortly after lift-off from the Wallops Flight Facility last October.

A Russian Progress resupply ship is scheduled to launch cargo to the station this coming Friday, July 3 from the Baikonur Cosmodrome in Kazakhstan. This will be followed in August by a Japanese HTV flight. Orbital ATK is moving ahead with plans for its next launch later this year.

Capturing a Dragon by the Tail on the ISS

The International Space Station has captured a dragon.

Dragon launches aboard its Falcon 9 rocket on Friday March 1 
Yes, I know. Sounds a bit strange right? But it's true. The Expedition 34 crew aboard the International Space Station have successfully grappled and docked the SpaceX Dragon capsule, carrying nearly 1300 pounds of cargo to support systems aboard the orbiting laboratory.

Dragon took off on top of a Falcon 9 rocket from the Cape Canaveral Air Force Station in Florida on Friday, on only its second flight to resupply the station(excluding test flights) destined for docking this morning. Some of the cargo that will be unpacked by the astronauts include 17 different scientific experiments, that will be studied in the weightless environment aboard the station, as well as crew supplies like food and clothing.

Grapple and docking procedures were carried out using the station's robotic arm- Canadarm2, by NASA astronaut and Expedition 34 Commander Kevin Ford, and fellow NASA astronaut and Flight Engineer Tom Marshburn. Once grappled, Dragon was installed onto the Earth-facing port of the ISS by a team working in Mission Control in Houston. Dragon was then bolted into place through commands by Flight Engineer Chris Hadfield of the Canadian Space Agency.

Catching a Dragon by the Tail
The station's Canadarm2 plucked  a dragon out of its 10 meter holding point, with official time of grappling occurring at 10.31am GMT. Dragon was then berthed to the space station's Harmony Module, with docking confirmed at 1:56pm GMT.

However, it is worth noting that the mission had to be delayed by one day due to a malfunction in the Dragon's solar arrays and thruster pods, shortly after launch on Friday, March 1st. This led to fears that SpaceX's Dragon mightn't be able to reach the 240 mile-high orbit of the ISS. Fortunately, these problems were eventually ironed out and teams on the ground gave the all-clear for a rendezvous with the station, followed by grapple and docking. The date for Dragon's unberthing, release and splashdown still remain planned for March 25.

This mission to resupply the ISS is SpaceX's second of 12 planned flights. It is hoped that if everything goes according to plan, astronauts will once again be able to launch from US soil into space, no longer having to rely on the Russians. The date for Dragon's first manned flight is expected to launch sometime in 2015.

In the mean time, while these private companies are flying back and forth from the ISS, NASA is now able to focus on going beyond low-earth orbit, and flying humans farther into space than ever before. The agency is currently developing systems, designs and hardware for its Space Launch System(SLS), and in particular, the Orion Multi-Purpose Crew Vehicle, scheduled to make its first test flight in 2014.
