KENNEDY SPACE CENTER, FL – Now just a day away, all systems are “GO” for blastoff of the next SpaceX Falcon 9 rocket carrying the Dragon CRS-6 cargo capsule on Monday, April 13, on a mission to the International Space Station (ISS) and a near simultaneous historic attempt to soft land the boosters first stage on a barge in a remote area of the Atlantic Ocean, hundreds of miles offshore from the US eastern seaboard.
In advance of Mondays launch attempt, SpaceX engineers successfully completed the practice countdown dress rehearsal and required static fire engine test this afternoon, Saturday, April 11, to ensure everything is ready with the rocket and first Stage Merlin 1-D engines for a safe and successful mission to the orbiting outpost.
The Dragon capsule has already been loaded with most of the cargo bound for the space station and was mated to the Falcon 9 booster earlier this week.
Although it is raining heavily now around the Florida Space Coast region along with multiple tornado warning threats, NASA and SpaceX officials are hopeful that weather conditions will clear sufficiently to permit Monday’s planned launch.
U.S. Air Force weather forecasters from the 45th Weather Squadron currently rate the chances of favorable conditions at launch time as 60 percent GO for liftoff of the sixth SpaceX commercial resupply services mission (CRS-6) to the ISS.
SpaceX and NASA are targeting blastoff of the Falcon 9 and Dragon CRS-6 spacecraft for Monday, April 13, slated at approximately 4:33 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
NASA Television plans live launch coverage starting at 3:30 p.m EDT: http://www.nasa.gov/multimedia/nasatv/index.html
SpaceX also plans live launch coverage beginning at 4:15pm EDT: www.spacex.com/webcast
The launch window is instantaneous, meaning that the rocket must liftoff at the precisely appointed time. Any delays due to weather or technical factors will force a scrub.
If all goes well with Mondays launch attempt, the Dragon spacecraft will rendezvous with the Earth orbiting outpost Wednesday, April 15, after a two day orbital chase.
In the event of a scrub for any reason, the backup launch day is 24 hours later on Tuesday, April 14, at approximately 4:10 p.m.
The Falcon 9 first stage is outfitted with four landing legs and grid fins to enable the landing attempt, which is a secondary objective of SpaceX. Cargo delivery to the station is the overriding primary objective and the entire reason for the CRS-6 mission.
The SpaceX plan is to direct the spent 1st stage on a precision guided rocket assisted descent from high altitude to accomplish a pinpoint soft landing onto a tiny platform in the middle of a vast ocean.
The ocean-going barge is known as the ‘autonomous spaceport drone ship’ (ASDS). It is being positioned some 200 to 250 miles offshore of the Carolina’s in the Atlantic Ocean along the rockets flight path flying along the US Northeast coast to match that of the ISS.
The ASDS measures only 300 by 100 feet, with wings that extend its width to 170 feet.
This marks the 2nd attempt by SpaceX to recovery the 14 story tall Falcon 9 first stage booster on the ASDS barge.
The first attempt in January during the CRS-5 mission was largely successful, as I wrote earlier at Universe Today, despite making a ‘hard landing’ on the ASDS. The booster 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.
Overall CRS-6 is the sixth SpaceX commercial resupply services mission and the seventh trip by a Dragon spacecraft to the station since 2012.
CRS-6 marks the company’s sixth 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 original Commercial Resupply Services (CRS) contract.
Dragon is packed with more than 4,300 pounds (1915 kilograms) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person Expedition 43 and 44 crews serving aboard the ISS.
The ship will remain berthed at the ISS for about five weeks.
The ISS cannot function without regular deliveries of fresh cargo by station partners from Earth.
Watch for Ken’s continuing onsite coverage of the CRS-6 launch from the Kennedy Space Center and Cape Canaveral Air Force Station.

Hunting for satellites from your backyard can be positively addicting. Sure, the Orion Nebula or the Andromeda Galaxy appear grand… and they’ll also look exactly the same throughout the short span of our fleeting human lifetimes. Since the launch of Sputnik in 1957, humans also have added their own ephemeral ‘stars’ to the sky. It’s fun to sleuth out just what these might be, as they photobomb the sky overhead. In the coming week, we’d like to turn your attention towards a unique opportunity to watch a high profile space launch approach a well-known orbiting space laboratory.
On Monday, April 13th 2015, SpaceX will launch its CRS-6 resupply mission headed towards the International Space Station. As of this writing, the launch is set for 20:33 Universal Time (UT) or 4:33 PM EDT. This is just over three hours prior to local sunset. The launch window to catch the ISS is instantaneous, and Tuesday April 14th at 4:10 PM EDT is the backup date if the launch does not occur on Monday.
Of course, launches are fun to watch up-close from the Kennedy Space Center. To date, we’ve seen two shuttle launches, one Falcon launch, and the MAVEN and MSL liftoffs headed to Mars from up close, and dozens more from our backyard about 100 miles to the west of KSC. We can typically follow a given night launch right through to fairing and stage one separation with binoculars, and we once even had a serendipitous launch occur during a local school star party! We really get jaded along the Florida Space Coast, where space launches are as common as three day weekend traffic jams elsewhere.
And it’s true that you can actually tell when a launch is headed ISS-ward, as it follows the station up the US eastern seaboard along its steep 52 degree inclination orbit.
On Monday, Dragon launches 23 minutes behind the ISS in its orbit. Viewers up should be able to follow CRS-6 up the U.S. East Coast in the late afternoon sky if it’s clear.
And of course, SpaceX will make another attempt Monday at landing its Falcon Stage 1 engine on a floating sea platform, known as the ‘autonomous spaceport drone ship’ (don’t call it a barge) after liftoff.
About 15-20 minutes after liftoff, Europe and the United Kingdom may catch the Dragon and Falcon S2 booster shortly after the ISS pass on the evening of April 13th. Observers ‘across the pond’ used to frequently catch sight of the Space Shuttle and the external fuel tank shortly after launch; such a sight is not to be missed!
Spotting Dragon ‘and friends’ on early orbits may provide for a fascinating show in the evenings leading up to capture and berthing. Typically, a Dragon launch generates four objects in orbit: the Dragon spacecraft, the Falcon Stage 2 booster, and the two solar panel covers. These were very prominent to us as they passed over Northern Maine on first orbit in the pre-dawn sky on the morning of January 10th, 2015. Universe Today science writer Bob King also noted that observers spotted what was probably a venting maneuver over Minnesota on the 2nd pass on the same date.
And even after berthing, the Falcon S2 booster and solar panel covers will stay up in orbit, either following or leading the ISS for several weeks before destructive reentry.
Orbits on Monday and Tuesday leading up to capture for Dragon on Wednesday April 15th at 7:14 AM EDT/11:14 UT will be the key times to sight the pair. Capture by the CanadaArm2 will take place over the central Pacific, and the Dragon will be berthed to the nadir Harmony node of the ISS. Dragon will remain attached to the station until May 17th for a subsequent return to Earth. With the end of the U.S. Space Shuttle program in 2011, SpaceX’s Dragon is currently the only vessel with a ‘down-mass’ cargo capability, handy for returning experiments to Earth.
The first few orbits on the night of the 13th for North America include a key pass for the US northeast at 1:04UT (on the 14th)/9:04 PM EDT, and subsequent passes at dusk westward about 90 minutes later. NASA’s Spot the Station App usually lists Dragon passes shortly after launch, as does Heavens-Above and numerous other tracking applications. We’ll also be publishing sighting opportunities for Dragon and the ISS, along with maps on Twitter as @Astroguyz as the info becomes available.
Pre-berthing passes next week favor 40-50 degrees north for evening passes, and 40-50 degrees south for morning viewing.
The International Space Station has become a busy place since its completion in 2009. To date, the station has been a port of call for the U.S. Space Shuttles, the Soyuz spacecraft with crews, and Progress, HTV, ATV and Dragon resupply craft.
The current expedition features astronaut Scott Kelly and cosmonaut Mikhail Korniyenko conducting a nearly yearlong stay on the ISS to study the effects that long duration spaceflight has on the human body. Kelley will also break the U.S. duration record by 126 days during his 342 stay aboard the station. The future may see Dragon ferrying crews to the ISS as early as 2017.
And you can always watch the launch live via NASA TV starting at 3:30 PM EDT/19:30 UT.
Don’t miss a chance to catch the drama of the Dragon spacecraft approaching the International Space Station, coming to a sky near you!
The clock is ticking towards the next launch of a SpaceX cargo vessel to the International Space Station (ISS) hauling critical supplies to the six astronauts and cosmonauts serving aboard, that now includes the first ever ‘One-Year Mission’ station crew comprising NASA’s Scott Kelly and Russia’s Mikhail Kornienko.
The mission, dubbed SpaceX CRS-6 (Commercial Resupply Services-6) will also feature the next daring attempt by SpaceX to recover the Falcon 9 booster rocket through a precision guided soft landing onto an ocean-going barge.
SpaceX and NASA are now targeting blastoff of the Falcon 9 rocket and Dragon spacecraft for Monday, April 13, just over a week from now, at approximately 4:33 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
NASA Television plans live launch coverage starting at 3:30 p.m.
The launch window is instantaneous, meaning that the rocket must liftoff at the precisely appointed time. Any delays due to weather or technical factors will force a scrub.
The backup launch day in case of a 24 hour scrub is Tuesday, April 14, at approximately 4:10 p.m.
Falcon 9 launches have been delayed due to issues with the rockets helium pressurization bottles that required investigation.
The Falcon 9 first stage is outfitted with four landing legs and grid fins to enable the landing attempt, which is a secondary objective of SpaceX. Cargo delivery to the station is the overriding primary objective and the entire reason for the mission.
An on time launch on April 13 will result in the Dragon spacecraft rendezvousing with the Earth orbiting outpost Wednesday, April 15 after a two day orbital chase.
After SpaceX engineers on the ground maneuver the Dragon close enough to the station, European Space Agency (ESA) astronaut Samantha Cristoforetti will use the station’s 57.7-foot-long (17-meter-long) robotic arm to reach out and capture Dragon at approximately 7:14 a.m. EDT on April 15.
Cristoforetti will be assisted by fellow Expedition 43 crew member and NASA astronaut Terry Virts, as they work inside the stations seven windowed domed cupola to berth Dragon at the Earth-facing port of the Harmony module.
Overall CRS-6 is the sixth SpaceX commercial resupply services mission and the seventh trip by a Dragon spacecraft to the station since 2012.
CRS-6 marks the company’s sixth 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 original Commercial Resupply Services (CRS) contract.
Dragon is packed with more than 4,300 pounds (1915 kilograms) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person Expedition 43 and 44 crews serving aboard the ISS.
The ship will remain berthed at the ISS for about five weeks.
The ISS cannot function without regular deliveries of fresh cargo by station partners from Earth.
The prior resupply mission, CRS-5, concluded in February with a successful Pacific Ocean splashdown and capsule recovery.
The CRS-5 mission also featured SpaceX’s history making attempt at recovering the Falcon 9 first stage as 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.
As I wrote earlier 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.
Listen to my live radio interview with BBC 5LIVE conducted in January 2015, discussing SpaceX’s first attempt to land and return their Falcon-9 booster.

Help ULA name America’s next rocket to space. Credit: ULA Voting Details below
Watch ULA’s March 25 Delta Launch Live – details below
Update 3/26: 2 new names have been added to the voting list – Zeus and Vulcan ![/caption]
United Launch Alliance (ULA) is asking the public for your help in naming their new American made rocket, now under development that “represents the future of space”- and will replace the firms current historic lines of Atlas and Delta rocket families that began launching back near the dawn of the space age.
Eagle, Freedom or GalaxyOne – those are the names to choose from for the next two weeks, from now until April 6.
UPDATE 3/26: 2 new names have been added to the voting list – Zeus and Vulcan !
ULA says the names were selected from a list of over 400 names submitted earlier this year by ULA’s 3400 employees and many space enthusiasts.
ULA has set up a simple voting system whereby you can vote for your favorite name via text or an online webpage.
Currently dubbed the “Next Generation Launch System,” or NGLS, ULA’s new president and CEO Tory Bruno is set to unveil the next generation rockets design and name at the National Space Symposium on April 13 in Colorado Springs, Colorado.
“ULA’s new rocket represents the future of space – innovative, affordable and reliable,” said Bruno, in a statement.
“More possibilities in space means more possibilities here on earth. This is such a critical time for space travel and exploration and we’re excited to bring all of America with us on this journey into the future.”
The NGLS is ULA’s response to what’s shaping up as a no holds barred competition with SpaceX for future launch contracts where only the innovative and those who dramatically cut the cost of access to space will survive.
The first flight of the NGLS is slated for 2019.
Here’s how you can cast your vote for America’s next rocket to April 6, 2015:
Voters can text 22333 to submit a vote for their favorite name. The following key can be used to text a vote:
• ULA1 for “Eagle”
• ULA2 for “Freedom”
• ULA3 for “GalaxyOne”
3/26 Update: Zeus and Vulcan have been added to the voting list
“Name America’s next ride to space. Vote early, vote often … ” says Bruno.
I have already voted – early and often.
Over 11,000 votes were tallied in just the first day.
Currently ULA is the nation’s premier launch provider, launching at a rate of about once per month. 13 launches are planned for 2015- as outlined in my earlier article here.
But ULA faces stiff and relentless pricing and innovative competition from NewSpace upstart SpaceX, founded by billionaire Elon Musk.
NGLS is ULA’s answer to SpaceX – they must compete in order to survive.
To date ULA has accomplished a 100 percent mission success for 94 launches since the firms founding in 2006 as a joint venture between Boeing and Lockheed Martin. They have successfully launched numerous NASA, national security and commercial payloads into orbit and beyond.
Planetary missions launched for NASA include the Mars rovers and landers Phoenix and Curiosity, Pluto/New Horizons, Juno, GRAIL, LRO and LCROSS.
ULA’s most recent launch for NASA involved the $1.1 Billion Magnetospheric Multiscale (MMS) mission comprised of four formation flying satellites which blasted to Earth orbit atop an Atlas V rocket from Cape Canaveral Air Force Station, Florida, during a spectacular nighttime blastoff on March 12, 2015. Read my onsite reports – here and here.
“Space launch affects everyone, every day, and our goal in letting America name its next rocket is to help all Americans imagine the future of endless possibilities created by affordable space launch,” Bruno added.
NGLS will include some heritage design from the Atlas V and Delta IV rockets, but will feature many new systems and potentially some reusable systems – to be outlined by Bruno on April 13.
ULA plans to phase out the Delta IV around 2019 when the current contracts are concluded. The Atlas V will continue for a transitional period.
The Atlas V is also the launcher for Boeing’s CST-100 manned space taxi due to first launch in 2017.
NGLS will launch from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida, the same pad as for the Atlas V, as well as from Vandenberg AFB, Calif.
ULA’s next Delta IV launch with GPS IIF-9 is scheduled shortly for Wednesday, March 25, with liftoff at 2:36 p.m. EDT from Cape Canaveral.

After a 17 year long wait, a new American mission to monitor intense solar storms and warn of impeding space weather disruptions to vital power grids, telecommunications satellites and public infrastructure was launched atop a SpaceXFalcon 9 on Wednesday, Feb. 11, from Cape Canaveral, Florida, to start a million mile journey to its deep space observation post.
The third time proved to be the charm when the Deep Space Climate Observatory, or DSCOVR science satellite lifted off at 6:03 p.m. EST Wednesday from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The spectacular sunset blastoff came after two scrubs this week forced by a technical problem with the Air Force tracking radar and adverse weather on Sunday and Tuesday.
The $340 million DSCOVR has a critical mission to monitor the solar wind and aid very important forecasts of space weather at Earth at an observation point nearly a million miles from Earth. It will also take full disk color images of the sunlit side of Earth at least six times per day that will be publicly available and “wow” viewers.
The couch sized probe was targeted to the L1 Lagrange Point, a neutral gravity point that lies on the direct line between Earth and the sun located 1.5 million kilometers (932,000 miles) sunward from Earth. At L1 the gravity between the sun and Earth is perfectly balanced and the satellite will orbit about that spot just like a planet.
L1 is a perfect place for the science because it lies outside Earth’s magnetic environment. The probe will measure the constant stream of solar wind particles from the sun as they pass by.
DSCOVR is a joint mission between NOAA, NASA, and the U.S Air Force (USAF) that will be managed by NOAA. The satellite and science instruments are provided by NASA and NOAA. The rocket was funded by the USAF.
The mission is vital because its solar wind observations are crucial to maintaining accurate space weather forecasts to protect US infrastructure such as power grids, aviation, planes in flight, all types of Earth orbiting satellites for civilian and military needs, telecommunications, ISS astronauts and GPS systems.
It will take about 150 days to reach the L1 point and complete satellite and instrument checkouts.
DSCOVR will then become the first operational space weather mission to deep space and function as America’s primary warning system for solar magnetic storms.
It will replace NASA’s aging Advanced Composition Explorer (ACE) satellite which is nearly 20 years old and far beyond its original design lifetime.
“DSCOVR is the latest example of how NASA and NOAA work together to leverage the vantage point of space to both understand the science of space weather and provide direct practical benefits to us here on Earth,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate in Washington.
DSCOVR was first proposed in 1998 by then US Vice President Al Gore as the low cost ‘Triana’ satellite to take near continuous views of the Earth’s entire globe to feed to the internet as a means of motivating students to study math and science. It was eventually built as a much more capable Earth science satellite that would also conduct the space weather observations.
But Triana was shelved for purely partisan political reasons and the satellite was placed into storage at NASA Goddard and the science was lost until now.
DSCOVR is equipped with a suite of four continuously operating solar science and Earth science instruments from NASA and NOAA.
It will make simultaneous scientific observations of the solar wind and the entire sunlit side of Earth.
The 750-kilogram (1250 pound) DSCOVR probe measures 54 inches by 72 inches.
The two Earth science instruments from NASA are the Earth Polychromatic Imaging Camera (EPIC) and the National Institute of Standards and Technology Advanced Radiometer (NISTAR).
EPIC will provide true color spectral images of the entire sunlit face of Earth at least six times per day, as viewed from an orbit around L1. They will be publically available within 24 hours via NASA Langley.
It will view the full disk of the entire sunlit Earth from sunrise to sunset and collect a variety of science measurements including on ozone, aerosols, dust and volcanic ash, vegetation properties, cloud heights and more.
Listen to my post launch interview with the BBC about DSCOVR and ESA’s successful IXV launch on Feb. 11.
Here’s a collection of a few of the newest sunrises, auroras, landscapes, nightlights, and more snapshots from the multinational crew of six astronauts and cosmonauts living and working aboard the ISS orbiting some 250 miles (400 kilometers) overhead.
And don’t forget that at sunset tonight (Feb. 8), a SpaceXFalcon 9 rocket is due to blastoff at 6:10 p.m., EST, if all goes well carrying the DSCOVR space weather satellite about a million miles (1.5 million kilometers) away to the L1 Lagrange point.
The Falcon 9 will blastoff from Cape Canaveral, Florida, pictured below:
Tens of millions of you are included in the lead sunrise photo of the U.S. East Coast – taken by ESA astronaut Samantha Cristoforetti perched aboard the orbiting lab complex.
And here’s a “speechless sunrise” taken today by NASA astronaut Terry Virts. We agree!
The current six person crew includes astronauts and cosmonauts from three nations; America, Russia and Italy including four men and two women serving aboard the massive orbiting lab complex.
They comprise Expedition 42 Commander Barry “Butch” Wilmore and Terry Virts from NASA, Samantha Cristoforetti from the European Space Agency (ESA) and cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.

Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
The long awaited Deep Space Climate Observatory, or DSCOVR science satellite is slated to blast off atop a SpaceX Falcon 9 on Sunday, Feb. 8, from Cape Canaveral, Florida on a mission to monitor the solar wind and aid very important forecasts of space weather at Earth.
DSCOVR is a joint mission between NOAA, NASA, and the U.S Air Force (USAF) that will be managed by NOAA. The satellite and science instruments are provided by NASA and NOAA.
Update Feb 8: Hold, Hold, Hold !!! 6:10 PM 2/8/15 Terminal Count aborted at T Minus 2 min 26 sec due to a tracking issue. NO launch of Falcon 9 today. rocket being safed now. next launch opportunity is Monday. Still TBD.
The rocket is provided by the USAF. SpaceX will try to recover the first stage via a guided descent to a floating barge in the Atlantic Ocean.
The weather outlook is currently very promising with a greater than 90 percent chance of favorable weather at launch time shortly after sunset on Sunday which could make for a spectacular viewing opportunity for spectators surrounding the Florida Space coast.
Liftoff atop the SpaceX Falcon 9 rocket is targeted for at 6:10:12 p.m. EST on Feb. 8, from Cape Canaveral Air Force Station Space Launch Complex 40.
There is an instantaneous launch window, meaning that any launch delay due to weather, technical or other factors will force a scrub to Monday.
The launch will be broadcast live on NASA TV: http://www.nasa.gov/nasatv
NASA’s DSCOVR launch blog coverage of countdown and liftoff will begin at 3:30 p.m. Sunday.
“DSCOVR is NOAA’s first operational space weather mission to deep space,” said Stephen Volz, assistant administrator of the NOAA Satellite and Information Service in Silver Spring, Maryland, at the pre-launch briefing today (Feb. 7) at the Kennedy Space Center in Florida.
The mission of DSCOVR is vital because its solar wind observations are crucial to maintaining accurate space weather forecasts to protect US infrastructure from disruption by approaching solar storms.
“DSCOVR will maintain the nation’s solar wind observations, which are critical to the accuracy and lead time of NOAA’s space weather alerts, forecasts, and warnings,” according to a NASA description.
“Space weather events like geomagnetic storms caused by changes in solar wind can affect public infrastructure systems, including power grids, telecommunications systems, and aircraft avionics.”
DSCOVR will replace NASA’s aging Advanced Composition Explorer (ACE) satellite which is nearly 20 years old and far beyond its original design lifetime.
The couch sized probe is being targeted to the L1 Lagrange Point, a neutral gravity point that lies on the direct line between Earth and the sun located 1.5 million kilometers (932,000 miles) sunward from Earth. At L1 the gravity between the sun and Earth is perfectly balanced and the satellite will orbit about that spot just like a planet.
L1 is a perfect place for the science because it lies outside Earth’s magnetic environment. The probe will measure the constant stream of solar wind particles from the sun as they pass by.
This will enable forecasters to give a 15 to 60 minute warning of approaching geomagnetic storms that could damage valuable infrastructure.
DSCOVR is equipped with a suite of four continuously operating solar science and Earth science instruments from NASA and NOAA.
It will make simultaneous scientific observations of the solar wind and the entire sunlit side of Earth.
The 750-kilogram DSCOVR probe measures 54 inches by 72 inches.
I saw the DSCOVR spacecraft up close at NASA Goddard Space Flight Center in Maryland last fall during processing in the clean room.
A secondary objective of the rocket launch for SpaceX is to conduct their second attempt to recover the Falcon 9 first stage booster on an ocean going barge. Read my articles about the first attempt in January 2015, starting here.
It was originally named ‘Triana’ (aka Goresat) and was conceived by then US Vice President Al Gore as a low cost satellite to take near continuous views of the Earth’s entire globe to feed to the internet as a means of motivating students to study math and science. It was eventually built as a much more capable Earth science satellite as well as to conduct the space weather observations.
But Triana was shelved for purely partisan political reasons and the satellite was placed into storage and the science was lost until now.
Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
In Kubrick’s and Clark’s 2001 Space Odyssey, there was no question of “Boots or Bots”[ref]. The monolith had been left for humanity as a mileage and direction marker on Route 66 to the stars. So we went to Jupiter and Dave Bowman overcame a sentient machine, shut it down cold and went forth to discover the greatest story yet to be told.
Now Elon Musk, born three years after the great science fiction movie and one year before the last Apollo mission to the Moon has set his goals, is achieving milestones to lift humans beyond low-Earth orbit, beyond the bonds of Earth’s gravity and take us to the first stop in the final frontier – Mars – the destination of the SpaceX odyssey.
Ask him what’s next and nowhere on his bucket list does he have Disneyland or Disney World. You will find Falcon 9R, Falcon Heavy, Dragon Crew, Raptor Engine and Mars Colonization Transporter (MCT).
At the top of his working list is the continued clean launch record of the Falcon 9 and beside that must-have is the milestone of a soft landing of a Falcon 9 core. To reach this milestone, Elon Musk has an impressive array of successes and also failures – necessary, to-be-expected and effectively of equal value. His plans for tomorrow are keeping us on the edge of our seats.
CRS-5, the Cargo Resupply mission number 5, was an unadulterated success and to make it even better, Elon’s crew took another step towards the first soft landing of a Falcon core, even though it wasn’t entirely successful. Elon explained that they ran out of hydaulic fluid. Additionally, there is a slew of telemetry that his engineers are analyzing to optimize the control software. Could it have been just a shortage of fluid? Yes, it’s possible they could extrapolate the performance that was cut short and recognize the landing Musk and crew dreamed of.
The addition of the new grid fins to improve control both assured the observed level of success and also assured failure. Anytime one adds something unproven to a test vehicle, the risk of failure is raised. This was a fantastic failure that provided a treasure trove of new telemetry and the possibilities to optimize software. More hydraulic fluid is a must but improvements to SpaceX software is what will bring a repeatable string of Falcon core soft landings.
“Failure is not an option,” are the famous words spoken by Eugene Kranz as he’s depicted in the movie Apollo 13. Failure to Elon Musk and to all of us is an essential part of living. However, from Newton to Einstein to Hawking, the equations to describe and define how the Universe functions cannot show failure otherwise they are imperfect and must be replaced. Every moment of a human life is an intertwined array of success and failure. Referring only to the final frontier, in the worse cases, teams fall out of balance and ships fall out of the sky. Just one individual can make a difference between his or a team’s success. Failure, trial and error is a part of Elon’s and SpaceX’s success.
He doesn’t quote or refer to Steve Jobs but Elon Musk is his American successor. From Hyperloops, to the next generation of Tesla electric vehicles, Musk is wasting no time unloading ideas and making his dreams reality. Achieving his goals, making milestones depends also on bottom line – price and performance into profits. The Falcon rockets are under-cutting ULA EELVs (Atlas & Delta) by more than half in price per pound of payload and even more with future reuse. With Falcon Heavy he will also stake claim to the most powerful American-made rocket.
Musk’s success will depend on demand for his product. News in the last week of his investments in worldwide space-based internet service also shows his intent to promote products that will utilize his low-cost launch solutions. The next generation of space industry could falter without investors and from the likes of Musk, re-investing to build demand for launch and sustaining young companies through their start-up phases. Build it and they will come but take for granted, not recognize the fragility of the industry, is at your own peril.
So what is next in the SpaceX Odyssey? Elon’s sights remain firmly on the Falcon 9R (Reuse) and the Falcon Heavy. Nothing revolutionary on first appearance, the Falcon Heavy will look like a Delta IV Heavy on steroids. Price and performance will determine its success – there is no comparison. It is unclear what will become of the Delta IV Heavy once the Falcon Heavy is ready for service. There may be configurations of the Delta IV with an upper stage that SpaceX cannot match for a time but either way, the US government is likely to effectively provide welfare for the Delta and even Atlas vehicles until ULA (Lockheed Martin and Boeing’s developed corporation) can develop a competitive solution. The only advantage remaining for ULA is that Falcon Heavy hasn’t launched yet. Falcon Heavy, based on Falcon 9, does carry a likelihood of success based on Falcon 9’s 13 of 13 successful launches over the last 5 years. Delta IV Heavy has had 7 of 8 successful launches over a span of 11 years.
The convergence of space science and technology and science fiction in the form of Musk’s visions for SpaceX is linked to the NASA legacy beginning with NASA in 1958, accelerated by JFK in 1962 and landing upon the Moon in 1969. The legacy spans backward in time to Konstantin Tsiolkovsky, Robert Goddard, Werner Von Braun and countless engineers and forward through the Space Shuttle and Space Station era.
The legacy of Shuttle is that NASA remained Earth-bound for 30-plus years during a time that Elon Musk grew up in South Africa and Canada and finally brought his visions to the United States. With a more daring path by NASA, the story to tell today would have been Moon bases or Mars missions completed in the 1990s and commercial space development that might have outpaced or pale in comparison to today’s. Whether Musk would be present in commercial space under this alternate reality is very uncertain. But Shuttle retirement, under-funding its successor, the Ares I & V and Orion, cancelling the whole Constellation program, then creating Commercial Crew program, led to SpaceX winning a contract and accelerated development of Falcon 9 and the Dragon capsule.
SpaceX is not meant to just make widgets and profit. Mars is the objective and whether by SpaceX or otherwise, it is the first stop in humankind’s journey into the final frontier. Mars is why Musk developed SpaceX. To that end, the first focal point for SpaceX has been the development of the Merlin engine.
Now, SpaceX’s plans for Mars are focusing on a new engine – Raptor and not a Merlin 2 – which will operate on liquified methane and liquid oxygen. The advantage of methane is its cleaner combustion leaving less exhaust deposits within the reusable engines. Furthermore, the Raptor will spearhead development of an engine that will land on Mar and be refueled with Methane produced from Martian natural resources.
The Raptor remains a few years off and the design is changing. A test stand has been developed for testing Raptor engine components at NASA’s Stennis Space Center. In a January Reddit chat session[ref] with enthusiasts, Elon replied that rather than being a Saturn F-1 class engine, that is, thrust of about 1.5 million lbf (foot-lbs force), his engineers are dialing down the size to optimize performance and reliability. Musk stated that plans call for Raptor engines to produce 500,000 lbf (2.2 million newtons) of thrust. While smaller, this represents a future engine that is 3 times as powerful as the present Merlin engine (700k newtons/157 klbf). It is 1/3rd the power of an F-1. Musk and company will continue to cluster engines to make big rockets.
To achieve their ultimate goal – Mars colonization, SpaceX will require a big rocket. Elon Musk has repeatedly stated that a delivery of 100 colonists per trip is the present vision. The vision calls for the Mars Colonization Transporter (MCT). This spaceship has no publicly shared SpaceX concept illustrations as yet but more information is planned soon. A few enthusiasts on the web have shared their visions of MCT. What we can imagine is that MCT will become a interplanetary ferry.
The large vehicle is likely to be constructed in low-Earth orbit and remain in space, ferrying colonists between Earth orbit and Mars orbit. Raptor methane/LOX engines will drive it to Mars and back. Possibly, aerobraking will be employed at both ends to reduce costs. Raptor engines will be used to lift a score of passengers at a time and fill the living quarters of the waiting MCT vehicle. Once orbiting Mars, how does one deliver 100 colonists to the surface? With atmospheric pressure at its surface equivalent to Earth’s at 100,000 feet, Mars does not provide an Earth-like aerodynamics to land a large vehicle.
In 1952, Werner Von Braun in his book “Mars Projekt” envisioned an armada of ships, each depending on launch vehicles much larger than the Saturn V he designed a decade later. Like the invading Martians of War of the Worlds, the armada would rather converge on Mars and deploy dozens of winged landing vehicles that would use selected flat Martian plain to skid with passengers to a safe landing. For now, Elon and SpaceX illustrate the landing of Dragon capsules on Mars but it will clearly require a much larger lander. Perhaps, it will use future Raptors to land softly or possibly employ winged landers such as Von Braun’s after robotic Earth-movers on Mars have constructed ten or twenty mile long runways.
We wait and see what is next for Elon Musk’s SpaceX vision, his SpaceX Odyssey. For Elon Musk and his crew, there are no “wives” – Penelope and families awaiting their arrival on Mars. Their mission is more than a five year journey such as Star Trek. The trip to Mars will take the common 7 months of a Hohmann transfer orbit but the mission is really measured in decades. In the short-term, Falcon 9 is poised to launch again in early February and will again attempt a soft landing on a barge at sea. And later, hopefully, in 2015, the Falcon Heavy will make its maiden flight from Cape Canaveral’s rebuilt launch pad 39A where the Saturn V lifted Apollo 11 to the Moon and the first, last and many Space Shuttles were launched.
Happy Birthday to my sister Sylvia who brought home posters, literature and interest from North American-Rockwell in Downey during the Apollo era and sparked my interest.
The Falcon Heavy is the brainchild of billionaire entrepreneur Elon Musk, SpaceX CEO and founder, and illustrates his moving forward with the firm’s next giant leap in spaceflight.
The rocket is designed to lift over 53 tons (117,00 pounds) to orbit and could one day launch astronauts to the Moon and Mars.
The commercial Falcon Heavy rocket has been under development by SpaceX for several years and the initial launch is now planned for later this year from Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.
The new rocket is comprised of three Falcon 9 cores.
The Falcon Heavy will be the most powerful rocket developed since NASA’s Saturn V rocket that hurled NASA’s Apollo astronauts to the Moon in the 1960s and 1970s – including the first manned landing on the Lunar surface by Neil Armstrong and Buzz Aldrin in July 1969.
Here is the updated animation of the SpaceX Falcon Heavy flight and booster recovery:

The video shows the launch of the triple barreled Falcon Heavy from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Then it transitions to the recovery of all three boosters by a guided descent back to a soft touchdown on land in the Cape Canaveral/Kennedy Space Center area.
SpaceX, headquartered in Hawthorne, CA, signed a long term lease with NASA in April 2014 to operate seaside pad 39A as a commercial launch facility for launching the Falcon Heavy as well as the manned Dragon V2 atop SpaceX’s man-rated Falcon 9 booster.
Launch Complex 39A has sat dormant for over three years since the blastoff of the final shuttle mission STS-135 in July 2011 on a mission to the International Space Station (ISS).
SpaceX is now renovating and modifying the pad as well as the Fixed and Mobile Service Structures, RSS and FSS. They will maintain and operate Pad 39A at their own expense, with no US federal funding from NASA.
When it does launch, the liquid fueled Falcon Heavy will become the most powerful rocket in the world according to SpaceX, generating nearly four million pounds of liftoff thrust from 27 Merlin 1D engines. It will then significantly exceeding the power of the Delta IV Heavy manufactured by competitor United Launch Alliance (ULA), which most recently was used to successfully launch and recover NASA’s Orion crew capsule on its maiden unmanned flight in Dec. 2014
SpaceX recently completed a largely successful and history making first attempt to recover a Falcon 9 booster on an ocean-going “drone ship.” The rocket nearly made a pinpoint landing on the ship but was destroyed in the final moments when control was lost due to a loss of hydraulic fluid.
Read my story with a SpaceX video – here – that vividly illustrates what SpaceX is attempting to accomplish by recovering and ultimately reusing the boosters in order to dramatically cut the cost of access to space.

“Robotic controllers let the CATS out of the bag!” So says NASA spokesman Dan Huot in a cool new NASA timelapse video showing in detail how CATS crawled around the space stations gangly exterior and clawed its way into its new home – topped off with a breathtaking view of our home planet that will deliver science benefits to us down below.
The CATS experiment was installed on the exterior of the International Space Station (ISS) via a first ever type of robotic handoff, whereby one of the stations robotic arms handed the rectangular shaped instrument off to a second robotic arm. Sort of like relays runners passing the baton while racing around the track for the gold medal.
In this case it was all in the name of science. CATS is short for Cloud Aerosol Transport System.
Ground controllers at NASA’s Johnson Space Center in Houston plucked CATS out of the truck of the recently arrivedSpaceX Dragon cargo delivery vehicle with the Special Purpose Dexterous Manipulator (Dextre). Then they passed it off to a Japanese team of controllers at JAXA, manipulating the second arm known as the Japanese Experiment Module Remote Manipulator System. The JAXA team then installed CATS onto an external platform on Japans Kibo laboratory.
CATS is a new Earth Science instrument dedicated to collecting continuous data about clouds, volcanic ash plumes and tiny airborne particles that can help improve our understanding of aerosol and cloud interactions and improve the accuracy of climate change models.
The remote-sensing laser instrument measures clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere that directly impacts the global climate.
Data from CATS will be used to derive properties of cloud/aerosol layers at three wavelengths: 355, 532, 1064 nm.

All the movements were conducted overnight by robotic flight controllers on the ground. They installed CATS to an external platform on Japan’s Kibo lab module.
CATS is helping to open a new era on the space station research dedicated to expanding its use as a science platform for making extremely valuable remote sensing observations for Earth Science.
The CATS instrument is the fourth successful NASA Earth science launch out of five scheduled during a 12-month period. And it is the second to be installed on the exterior of the ISS, following ISS-RapidScat that was brought by the SpaceX CRS-4 Dragon.
The fifth launch — the Soil Moisture Active Passive satellite — is scheduled for Jan. 29 from Vandenberg Air Force Base in California.
CATS was launched to the station as part of the payload aboard the SpaceX Dragon CRS-5 cargo vessel bolted atop the SpaceX Falcon 9 for the spectacular nighttime blastoff on Jan. 10 at 4:47 a.m. EST from Cape Canaveral Air Force Station in Florida.
CATS was loaded in the unpressurized rear trunk section of Dragon.
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.
