If all goes as hoped, SpaceX will have a very busy 2015. The commercial space company could launch as many as 17 rockets, including a mid-flight test abort of the Dragon capsule to demonstrate its in-flight crew escape system. Then there’s the launch that every rocket aficionado one has been waiting for: the demonstration mission of the 27-engine Falcon Heavy rocket.
Already, SpaceX has launched one mission in 2015, the CRS-5 Dragon resupply mission for the International Space Station that was delayed from December 2014. In addition to successfully hooking up with the ISS, SpaceX also tested out a flyback and landing system for the Falcon 9 first stage, which was deemed “mostly successful” despite a spectacular explosion when it careened off the target, a floating ocean barge. The next test of the landing system will occur with the launch of the solar wind monitoring DSCOVR satellite, which has just been delayed slightly to February 9.
Next rocket landing on drone ship in 2 to 3 weeks w way more hydraulic fluid. At least it shd explode for a diff reason.

While SpaceX itself does not list upcoming launch dates on its own website, a site put together by SpaceX enthusiast Lukas Davia called SpaceXStats has garnered a list of potential launch dates from NASA and other customers, and they say up to 16 more launches could take place this year. SpaceX will be launching more space station resupply missions, commercial satellite launch missions, and US government science and national security missions.
Delays like the recently announced launch delay for DSCOVR, will greatly impact how many launches SpaceX will be able to conduct this year. Musk has said his company could launch about one rocket per month during 2015, while other sources predict 10-12 launches for the commercial company.
As reported in Spaceflightnow.com, SpaceX had a similar number of flights on its docket in 2014, including the Falcon Heavy’s debut launch and the Dragon abort tests, which has slipped to be on the launch manifest for 2015. Six Falcon 9 rockets ended up blasting off last year.
Most of the missions will take off from Cape Canaveral’s launch complex, where up to 24 launches could take place this year. Along with the launches from SpaceX, United Launch Alliance has launches schedule for satellites for the U.S. military, NASA and commercial companies.

The Falcon Heavy was originally scheduled for its first test flight in late 2012 or early 2013 from Vandenberg Air Force Base, California, but it now will launch from the refurbished pads at Cape Canaveral. SpaceX says this rocket was designed from the outset to carry humans into space and “restores the possibility of flying missions with crew to the Moon or Mars.”
The Falcon Heavy will lift over 53 metric tons (117,000 lb) to orbit, about three times the performance of the Falcon 9. It is comprised of three nine-engine Falcon 9 first stage booster cores and uses upgraded Merlin 1D engines.

See video below[/caption]
Dramatic new photos and video of the daring and mostly successful attempt by Space X to land their Falcon 9 booster on an ocean-going “drone ship” were released this morning, Friday, Jan. 16, by SpaceX CEO and founder Elon Musk.
Musk posted the imagery online via his twitter account and they vividly show just how close his team came to achieving total success in history’s first attempt to land and recover a rocket on a tiny platform in the ocean.
Here’s the video: “Close, but no cigar. This time.”
The rocket landing and recovery attempt was a secondary objective of SpaceX, that immediately followed the spectacular nighttime blastoff of the Falcon 9 on Jan. 10 carrying the SpaceX Dragon cargo freighter spacecraft on a critical resupply mission for NASA bound for the space station.
The history making attempt at recovering the Falcon 9 first stage was a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a miniscule platform at sea using a rocket assisted descent by the first stage Merlin engines aided by steering fins.
The first stage rocket reached an altitude of over 100 miles after firing nine Merlins as planned for nearly three minutes. It had to be slowed from traveling at a velocity of about 2,900 mph (1300 m/s). The descent maneuver has been likened to someone balancing a rubber broomstick on their hand in the middle of a fierce wind storm.
The imagery shows the last moments of the descent as the rocket hits the edge of the drone ship at a 45 degree angle with its four landing legs extended and Merlin 1D engines firing.
Musk tweeted that the first stage Falcon 9 booster ran out of hydraulic fluid and thus hit the barge.
“Rocket hits hard at ~45 deg angle, smashing legs and engine section,” Musk explained today.
Lacking hydraulic fluid the boosters attached steering fins lost power just before impact.
“Before impact, fins lose power and go hardover. Engines fights to restore, but …,” Musk added.
This ultimately caused the Falcon 9 to crash land as the legs and engine section were smashed and destroyed as the fuel and booster burst into flames. The ship survived no problem.
“Residual fuel and oxygen combine.”
“Full RUD (rapid unscheduled disassembly) event. Ship is fine minor repairs. Exciting day!” said Musk.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted within hours after the launch and recovery attempt.
As I wrote on launch day here at Universe Today, despite making a ‘hard landing’ on the vessel dubbed the ‘autonomous spaceport drone ship,’ the 14 story tall Falcon 9 first stage did make it to the drone ship, positioned some 200 miles offshore of the Florida-Carolina coast, northeast of the launch site in the Atlantic Ocean. The rocket broke into pieces upon hitting the barge.
Whereas virtually every other news outlet quickly declared the landing attempt a “Failure” in the headline, my assessment as a scientist and journalist was the complete opposite!!
In my opinion the experiment was “a very good first step towards the bold company goal of recovery and re-usability in the future” as I wrote in my post launch report here at Universe Today.
Listen to my live radio interview with BBC 5LIVE conducted Saturday night (Jan. 11 UK time), discussing SpaceX’s first attempt to land and return their Falcon-9 booster.
“Is it safe? Was SpaceX brave or foolhardy? Why is this significant? Will SpaceX succeed in the future?” the BBC host asked me.
I replied; “It was a 99% success” and more …..
“Am super proud of my crew for making huge strides towards reusability on this mission. You guys rock!” Musk declared in a later tweet.
SpaceX achieved virtually all of their objectives in the daunting feat except for a soft landing on the drone ship.
This was a bold experiment involving re-lighting one of the first stage Merlin 1D engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.
Four attached hypersonic grid fins and a trio of Merlin propulsive burns succeeded in slowing the booster from hypersonic velocity to subsonic and guiding it to the ship.
The drone ship measures only 300 feet by 170 feet. That’s tiny compared to the Atlantic Ocean.
The first stage was planned to make the soft landing by extending four landing legs to a width of about 70 feet to achieve an upright landing on the platform with a accuracy of 30 feet (10 meters).
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.
So they will learn and move forward to the next experimental landing, that could come as early as a few weeks on the launch of the DSCOVR mission in late January or early February.
“Upcoming flight already has 50% more hydraulic fluid, so should have plenty of margin for landing attempt next month.”
Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.
It remains to be seen whether his vision of reusing rockets can be made economical. Most of the space shuttle systems were reused, except for the huge external fuel tanks, but it was not a cheap proposition.
But we must try to cut rocket launch costs if we hope to achieve routine and affordable access to the high frontier and expand humanity’s reach to the stars.
The Falcon 9 launch itself was a flawless success, blasting off at 4:47 a.m. EST on Jan. 10 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The Dragon CRS-5 spacecraft was loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, the CATS science payload, student research investigations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person crew serving aboard the ISS.
It successfully rendezvoused at the station on Jan. 12 after a two day orbital chase, delivering the critical cargo required to keep the station stocked and humming with science.
Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
The commercial SpaceX cargo Dragon, loaded with over 2.6 tons of critically needed supplies and science experiments, was captured by the crew aboard the International Space Station (ISS) this morning (Jan. 12) while soaring over the Mediterranean Sea.
The SpaceX Dragon CRS-5 cargo vessel arrived at the station following a flawless two day orbital pursuit and spectacular nighttime blastoff atop the SpaceX Falcon 9 on Jan. 10 at 4:47 a.m. EST from Cape Canaveral Air Force Station in Florida.
Note: This breaking news story is being updated. Check back frequently for updates.
Dragon was successfully berthed and bolted into place a few hours later at 8:54 a.m. EST.
Working at the robotics work station inside the seven windowed domed cupola, Expedition 42 Commander Barry “Butch” Wilmore of NASA, with the assistance of Flight Engineer Samantha Cristoforetti of the European Space Agency, successfully captured the Dragon spacecraft with the station’s Canadian-built robotic arm at 5:54 a.m. EST.
Wilmore grappled Dragon with the station’s 57-foot-long (17-meter-long) robotic arm at 5:54 a.m. EST, about 18 minutes ahead of schedule, in an operation shown live on NASA TV, back-dropped by breathtaking views of “our beautiful Earth” passing by some 260 miles (410 kilometers) below.
Among the goodies aboard are belated Christmas presents for the crew. The Falcon 9 and Dragon were originally scheduled to liftoff in December and arrive in time for the Christmas festivities.
The cargo freighter flew beneath the station to arrive at the capture point 32 feet (10 meters) away. Dragon’s thrusters were disabled at the time of grappling.
Robotics officers at Houston Mission Control then began remotely maneuvering the arm to berth Dragon at the Earth-facing port on the station’s Harmony module starting at 7:45 a.m. EST.
Dragon is being attached via the common berthing mechanism (CBM) using four gangs of four bolts apiece to accomplish a hard mate to Harmony. The overall grappling and berthing process requires a few hours.
Dragon was successfully berthed and bolted into place at 8:54 a.m. EST and its now part of the space station.
The crew will conduct leak pressure checks, remove the docking mechanism and open the hatch later today or tomorrow.
CRS-5 marks the company’s fifth operational 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 station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s Commercial Resupply Services (CRS) contract.
Overall this is the sixth Dragon to arrive at the ISS.
The ISS cannot function without regular deliveries of fresh cargo by station partners from Earth.
The Dragon CRS-5 spacecraft is loaded with over 5108 pounds (2317 kg) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing, and assorted research gear for the six person crew serving aboard the ISS.
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 that directly impact the global climate.
CATS is loaded aboard the unpressurized trunk of Dragon.
Also loaded onboard are 17 student experiments known collectively as the “Yankee Clipper” mission. The experiments are sponsored by the National Center for Earth and Space Science Education, which oversees the Student Spaceflight Experiments Program (SSEP) in partnership with NanoRacks LLC.
The launch marked the first US commercial resupply launch since the catastrophic destruction of an Orbital Sciences Antares rocket and Cygnus Orb-3 spacecraft bound for the ISS which exploded unexpectedly after launch from NASA Wallops, VA, on Oct. 28, 2014.
The US supply train to the ISS is now wholly dependent on SpaceX until Cygnus flights are resumed, hopefully by late 2015, on an alternate rocket, the Atlas V.
Dragon will remain attached to the ISS for about four weeks until Feb. 10.
SpaceX also had a secondary objective of recovering the Falcon 9 booster’s first stage via an unprecedented precision guided landing on an ocean-going “drone.”
The history making attempt at recovering the Falcon 9 first stage was a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a tiny platform in the middle of a vast ocean using a rocket assisted descent.
In my opinion the experiment was “a very good first step towards the bold company goal of recovery and re-usability in the future” as I wrote in my post launch report here at Universe Today.

“Huge strides towards [rocket] reusability” were achieved, says SpaceX CEO Elon Musk, following Saturday morning’s (Jan. 10) flawless launch of his firm’s Falcon 9 rocket on a critical resupply mission to the space station for NASA, which also had a secondary objective of recovering the booster’s first stage via an unprecedented precision-guided landing on an ocean-going “drone.”

The rocket broke into pieces upon hitting the barge.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted soon after the launch and recovery attempt.
The drone ship, along with pieces of the rocket, was towed back to the Port of Jacksonville, FL, this afternoon, Sunday, Jan. 11. Photos captured by locals, and posted today on Reddit, NASASpaceflight and Spaceflight Now, showed the ship was intact with some damage, as reported by Musk.
The goal of the commercial Falcon 9 rocket was to launch the SpaceX Dragon CRS-5 cargo vessel on a mission bound for the International Space Station (ISS). It lit up the night skies all around the Florida Space Coast following a flawless liftoff at 4:47 a.m. EST from Cape Canaveral Air Force Station.
After a two day chase, Dragon will reach the ISS at about 6:12 a.m. EST on Monday, Jan. 12. NASA TV live coverage starts at 4:30 a.m. EST.

“Grid fins worked extremely well from hypersonic velocity to subsonic, but ran out of hydraulic fluid right before landing,” Musk tweeted.
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land, and several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.

SpaceX successfully launched their commercial Falcon 9 rocket and Dragon cargo ship on a critical mission for NASA bound for the space station this morning, Jan. 10, while simultaneously accomplishing a hard landing of the boosters first stage on an ocean-floating “drone ship” platform in a very good first step towards the bold company goal of recovery and re-usability in the future.
The spectacular night time launch of the private SpaceX Falcon 9 rocket lit up the skies all around the Florida Space Coast and beyond following a flawless on time liftoff at 4:47 a.m. EST from Cape Canaveral Air Force Station.
The nine Merlin 1D engines of the 208 foot-tall Falcon 9 generated 1.3 million pounds of liftoff thrust as the rocket climbed to orbit on the first SpaceX launch of 2015.
The Dragon CRS-5 mission is on its way to a Monday-morning rendezvous with the International Space Station (ISS).
It is loaded with more than two tons of supplies and NASA science investigations for the six person crew aboard the massive orbiting outpost.
A secondary goal of SpaceX was to conduct a history-making attempt at recovering the 14 story tall Falcon 9 first stage via a precision landing on an ocean-going landing platform known as the “autonomous spaceport drone ship.”
SpaceX CEO Elon Musk quickly tweeted that good progress was made, and as expected, more work needs to be done.
This was an experiment involving re-lighting one of the first stage Merlin engines three times to act as a retro rocket to slow the stages descent and aim for the drone ship.
“Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho,” Musk tweeted soon after the launch and recovery attempt.
“Ship itself is fine. Some of the support equipment on the deck will need to be replaced…”
“Didn’t get good landing/impact video. Pitch dark and foggy. Will piece it together from telemetry and … actual pieces.”
Musk’s daring vision is to recover, refurbish and reuse the first stage and dramatically reduce the high cost of access to space, by introducing airline like operational concepts.
The ‘autonomous spaceport drone ship’ was positioned some 200 to 250 miles offshore of the launch site in the Atlantic Ocean along the rockets flight path, flying along the US Northeast coast to match that of the ISS.
The autonomous spaceport drone ship measure only 300 by 100 feet, with wings that extend its width to 170 feet. That’s tiny compared to the Atlantic Ocean.
Therefore the SpaceX team was successful in accomplishing a rocket assisted descent and pinpoint landing in the middle of a vast ocean, albeit not as slow as hoped.
No one has ever tried such a landing attempt before in the ocean says SpaceX. The company has conducted numerous successful soft landing tests on land. And several soft touchdowns on the ocean’s surface. But never before on a barge in the ocean.

“We are delighted to kick off 2015 with our first commercial cargo launch of the year,” said NASA Administrator Charles Bolden in a statement.
“Thanks to our private sector partners, we’ve returned space station resupply launches to U.S. soil and are poised to do the same with the transport of our astronauts in the very near future.”
“Today’s launch not only resupplies the station, but also delivers important science experiments and increases the station’s unique capabilities as a platform for Earth science with delivery of the Cloud-Aerosol Transport System, or CATS instrument. I congratulate the SpaceX and NASA teams who have made today’s success possible. We look forward to extending our efforts in commercial space to include commercial crew by 2017 and to more significant milestones this year on our journey to Mars.”

Solar wind – that is, the stream of charged electrons and protons that are released from the upper atmosphere of the Sun – is a constant in our Solar System and generally not a concern for us Earthlings. However, on occasion a solar wind shock wave or Coronal Mass Ejection can occur, disrupting satellites, electronics systems, and even sending harmful radiation to the surface.
Little wonder then why NASA and the National Oceanic and Atmospheric Administration (NOAA) have made a point of keeping satellites in orbit that can maintain real-time monitoring capabilities. The newest mission, the Deep Space Climate Observatory (DSCOVR) is expected to launch later this month.
A collaborative effort between NASA, the NOAA, and the US Air Force, the DSCOVR mission was originally proposed in 1998 as a way of providing near-continuous monitoring of Earth. However, the $100 million satellite has since been re-purposed as a solar observatory.
In this capacity, it will provide support to the National Weather Service’s Space Weather Prediction Center, which is charged with providing advanced warning forecasts of approaching geomagnetic storms for people here on Earth.
These storms, which are caused by large-scale fluctuations in solar wind, have the potential of disrupting radio signals and electronic systems, which means that everything from telecommunications, aviation, GPS systems, power grids, and every other major bit of infrastructure is vulnerable to them.
In fact, a report made by the National Research Council estimated that recovering from the most extreme geomagnetic storms could take up to a decade, and cost taxpayers in the vicinity of $1 to $2 trillion dollars. Add to the that the potential for radiation poisoning to human beings (at ground level and in orbit), as well as flora and fauna, and the need for alerts becomes clear.
Originally, the satellite was scheduled to be launched into space on Jan. 23rd from the Cape Canaveral Air Force Station, Florida. However, delays in the latest resupply mission to the International Space Station have apparently pushed the date of this launch back as well.
According to a source who spoke to SpaceNews, the delay of the ISS resupply mission caused scheduling pressure, as both launches are being serviced by SpaceX from Cape Canaveral. However, the same source indicated that there are no technical problems with the satellite or the Falcon 9 that will be carrying it into orbit. It is now expected to be launched on Jan. 29th at the latest.
Once deployed, DSCOVR will eventually take over from NASA’s aging Advanced Composition Explorer (ACE) satellite, which has been in providing solar wind alerts since 1997 and is expected to remain in operation until 2024. Like ACE, the DSCOVER will orbit Earth at Lagrange 1 Point (L1), the neutral gravity point between the Earth and sun approximately 1.5 million km (930,000 mi) from Earth.
From this position, DSCOVR will be able to provide advanced warning, roughly 15 to 60 minutes before a solar wind shockwave or CME reaches Earth. This information will be essential to emergency preparedness efforts, and the data provided will also help improve predictions as to where a geomagnetic storm will impact the most.
These sorts of warnings are essential to maintaining the safety and integrity of infrastructure, but also the health and well-being of people here on Earth. Given our dependence on high-tech navigation systems, electricity, the internet, and telecommunications, a massive geomagnetic storm is not something we want to get caught off guard by!

Rocket science is difficult stuff, but we don’t always necessarily have to explain it that way. It’s important at times to break science down as simply as we can, for purposes ranging from simple understanding to making it accessible to children.
A couple of days ago, SpaceX posted a brilliant parody of a famous xkcd cartoon to describe the organization’s Falcon 9 rocket. Called “Bird 9”, it describes the components of the rocket using only the words that are used most often in speech.
The result is brilliant, with the top of the rocket called “stuff going into space” and the rocket stage aiming for a drone landing soon nicknamed “part that folds out when the first part is just above the big boat”. We won’t spoil any more for you; click on the infographic below so you can see it in its full glory. We’ve also included the original xkcd cartoon for reference.
