The science team leading NASA’s long-lived Opportunity rover mission is honoring the pioneering solo nonstop trans-Atlantic flight of aviator Charles Lindbergh by assigning key features of the Mars mountain top crater area the rover is now exploring with names related to the historic flight.
Opportunity is now studying an elongated crater called “Spirit of St. Louis” and an unparalleled rock spire within the crater called “Lindbergh Mound” which are named in honor of Lindbergh himself and his plane – the Spirit of Saint Louis.
“Spirit of Saint Louis” crater is quite special in many ways related not just to history but also to science and exploration – that very reasons behind Lindbergh’s flight and Opportunity’s astounding mission to the Red Planet.
The team is ecstatic that the 11 year old rover Opportunity has reached “Spirit of St. Louis Crater” because its serves as the gateway to the alien terrain of “Marathon Valley” holding caches of water altered minerals that formed under environmental conditions conducive to support Martian microbial life forms, if they ever existed.
The crater, rock spire and several features in and near it are shown in several recent panoramic mosaics, above and below, created by the rover team and separately by the image processing team of Ken Kremer and Marco Di Lorenzo.

Marathon Valley and Spirit of St. Louis Crater are located just a few hundred meters south of a Mars mountain summit at a majestic spot called Cape Tribulation. It lies along a marvelous ridgeline along the western rim of Endeavour crater, which spans some 22 kilometers (14 miles) in diameter.
“What’s the connection between St. Louis and the Spirit of St. Louis? Lindbergh flew from New York to Paris, but he named his aircraft for the St. Louis citizens who purchased it for him,” says Prof. Ray Arvidson, the rover Deputy Principal Investigator of Washington University in St. Louis.
The raw images for the mosaics were taken in March and April 2015 using the robots mast mounted pancam and navcam cameras. The mosaics are shown in false color and colorized versions, annotated and unannotated.
Charles Lindbergh embarked in May 1927 on his history making flight from New York to Paris in the airplane he named Spirit of St. Louis, the first solo nonstop flight across the Atlantic.

The shallow Spirit of St. Louis Crater is about 110 feet (34 meters) long and about 80 feet (24 meters) wide, with a floor slightly darker than surrounding terrain, says NASA.
Lindbergh Mound dominates the crater measuring about 7 to 10 feet (2 to 3 meters) tall, rising higher than the crater’s rim.
The annotations also include features named to recognize the financial backing for the flight from St. Louis residents including Harold M. Bixby and Harry M. Knight. The plane’s designer was Donald A. Hall.

Among other features named are Roosevelt Field, the spot on New York’s Long Island from which Lindbergh took off, and Marathon Monument, where the rover completed a her first marathon distance runners drive on Mars. The team picked a distinctive outcrop, Marathon Monument, to mark the finish line, said NASA officials.
“The science team for the rover picks crater names from a list of “vessels of exploration,” including ships of sail and spacecraft as well as aircraft. As long as the rover remains in the crater, names for interesting features will drawn from a list of names related to this famous flight,” according to a NASA statement.

SpaceX Dragons seem to be flying nearly everywhere these days, coming and going at a record pace to the delight and relief of NASA, researchers and the space faring crews serving aboard the International Space Station (ISS). As one Dragon returned to Earth from space today, May 21, another Dragon prepares to soar soon to space.
The commercial SpaceX-6 cargo Dragon successfully splashed down in the Pacific Ocean at 12:42 p.m. EDT (1642 GMT) today, Thursday, about 155 miles southwest of Long Beach, California, some five hours after it was released from the grip of the stations robotic arm this morning at 7:04 a.m. EDT by the Expedition 43 crew as the craft were flying some 250 miles (400 km) above Australia.
The ocean splashdown marked the conclusion to the company’s sixth cargo resupply mission to the ISS under a commercial contract with NASA. Overall this was the seventh trip by a Dragon spacecraft to the station since the inaugural flight in 2012.
Following the launch failure and uncontrolled destructive plummet back to Earth of the Russian Progress 59 cargo freighter earlier this month, the station and its six person international crews are more dependent than ever on the SpaceX commercial supply train to orbit to keep it running and humming with productive science.
Working from a robotics work station in the domed cupola, NASA astronaut Scott Kelly released the Dragon CRS-6 spacecraft from the grappling snares of the 57.7-foot-long (17-meter-long) Canadian-built robotic arm with help from fellow NASA astronaut Terry Virts. Kelly is a member of the first 1 Year ISS mission crew, along with Russian cosmonaut Mikhail Kornienko.
The capsule then performed an intricate series of three departure burns and maneuvers to move beyond the imaginary 656-foot (200-meter) “keep out sphere” around the station and begin its five and a half hour long trip back to Earth.
The station crew had packed Dragon with almost 3,100 pounds of NASA cargo from the International Space Station. The including research samples pertaining to a host of experiments on how spaceflight and microgravity affect the aging process and bone health as well as no longer need items and trash to reduce station clutter.

“Spaceflight-induced health changes, such as decreases in muscle and bone mass, are a major challenge facing our astronauts,” said Julie Robinson, NASA’s chief scientist for the International Space Station Program Office at NASA’s Johnson Space Center in Houston, in a statement.
“We investigate solutions on the station not only to keep astronauts healthy as the agency considers longer space exploration missions but also to help those on Earth who have limited activity as a result of aging or illness.”
The Dragon was retrieved from the ocean by recovery boats following the parachute assisted splashdown. It will be transported to Long Beach, California for removal and return of the NASA cargo. The capsule itself will be shipped to SpaceX’s test facility in McGregor, Texas, for processing to remove cargo and inspection of its performance.

“The returning Space Aging study, for example, examines the effects of spaceflight on the aging of roundworms, widely used as a model for larger organisms,” noted NASA in a statement.
“By growing millimeter-long roundworms on the space station, researchers can observe physiological changes that may affect the rate at which organisms age. This can be applied to changes observed in astronauts, as well, particularly in developing countermeasures before long-duration missions.”
Dragon departed after having spent a record setting stay of 33 days berthed to the station at an Earth facing port on the Harmony node.
Dragon is also the only current US means for sending cargo to the station after the loss of the Orbital Sciences Cygnus craft in the Antares rocket explosion last October.
The SpaceX CRS-6 Dragon successfully blasted off atop a Falcon 9 booster from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida on April 14, 2015 at 4:10 p.m. EDT (2010:41 GMT) on the CRS-6 (Commercial Resupply Services-6) mission.

The resupply vessel had arrived three days later on April 17 and was successfully snared by the Expedition 43 Flight Engineer Samantha Cristoforetti of the European Space Agency, the first female Italian astronaut.
Dragon launched on April 14 with more than 4,300 pounds of supplies, science experiments, and technology demonstrations, including critical materials to support about 40 of more than 250 science and research investigations during the station’s Expeditions 43 and 44.
An Espresso machine was also aboard and delivered to enhance station morale during the daily grind some 250 miles above Earth.
Among the research investigations were a fresh batch of 20 rodents for the Rodent Research Habitat, and experiments on osteoporosis to counteract bone deterioration in microgravity, astronaut vision loss, protein crystal growth, and synthetic muscle for prosthetics and robotics.
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.
Following the complete success of the SpaceX Dragon CRS-6 mission, NASA just announced that the next SpaceX Dragon is currently slated to launch on June 26 at 11:09 a.m. EDT.
The Dragon will carry critical US equipment enabling docking by the SpaceX Crew Dragon and Boeing CST-100 astronaut transporters.

The X-37B, a reusable Air Force space plane launched today, May 20, from Cape Canaveral, Florida, on its fourth mission steeped in mystery as to its true goals for the U.S . military and was accompanied by ten tiny cubesat experiments for NASA and the NRO, including a solar sailing demonstration test for The Planetary Society.
The military space plan successfully blasted off for low Earth orbit atop a 20 story United Launch Alliance (ULA) Atlas V rocket on the clandestine Air Force Space Command 5 (AFSPC-5) satellite mission for the U.S. Air Force Rapid Capabilities Office at 11:05 a.m. EDT (1505 GMT) today, May 20, from Space Launch Complex-41 on Cape Canaveral Air Force Station, Florida.
The weather cooperated for a spectacular liftoff from the Florida space coast, which was webcast live by ULA until five minutes after launch when it went into a communications blackout shortly after announcing the successful ignition of the Centaur upper stage.
The exact launch time was classified until it was released by the Department of Defense this morning. Early this morning the four hour launch window was narrowed down to two small windows of opportunity.

Among the experiments for the flight are 10 CubeSats housed in the Aft Bulkhead Carrier (ABC) located below the Centaur upper stage. Together they are part of the National Reconnaissance Office’s (NRO’s) Ultra Lightweight Technology and Research Auxiliary Satellite (ULTRASat). The 10 CubeSats in ULTRASat are managed by the NRO and NASA. They are contained in eight P-Pods from which they will be deployed in the coming days.
Also aboard the X-37B is a NASA materials science experiment called METIS and an advanced Hall thruster experiment. The Hall thruster is a type of electric propulsion device that produces thrust by ionizing and accelerating a noble gas, usually xenon.
Following primary spacecraft separation the Centaur will change altitude and inclination in order to release the CubeSat spacecraft.
They are sponsored by the National Reconnaissance Office (NRO) and NASA and were developed by the U.S. Naval Academy, the Aerospace Corporation, the Air Force Research Laboratory, California Polytechnic State University, and The Planetary Society.
LightSail marks the first controlled, Earth orbit solar sail flight according to the non-profit Planetary Society. Photons from the sun should push on the solar sails.
“The purpose of this LightSail demonstration test is to verify telemetry, return photos return and to test the deployment of the solar sails,” said Bill Nye, the Science Guy), and President of The Planetary Society, during the X-37B launch webcast.
“LightSail is comprised of three CubeSats that measure about 30 cm by 10 cm.”
“It’s smaller than a shoebox, everybody! And the sail that will come out of it is super shiny mylar. We’re very hopeful that the thing will deploy properly, the sunlight will hit it and we’ll get a push.”

The Boeing-built X-37B is an unmanned reusable mini shuttle, also known as the Orbital Test Vehicle (OTV) and is flying on the OTV-4 mission. It launches vertically like a satellite but lands horizontally like an airplane and functions as a reliable and reusable space test platform for the U.S. Air Force.
“ULA is honored to launch this unique spacecraft for the U.S Air Force. Congratulations to the Air Force and all of our mission partners on today’s successful launch! The seamless integration between the Air Force, Boeing, and the entire mission team culminated in today’s successful launch of the AFSPC-5 mission” said Jim Sponnick, ULA vice president, Atlas and Delta Programs.
The two stage Atlas V stands 206 feet tall and weighs 757,000 pounds.
The X-37B was carried to orbit by the Atlas V in its 501 configuration which includes a 5.4-meter-diameter payload fairing and no solid rocket motors. The Atlas first stage booster for this mission was powered by the RD AMROSS RD-180 engine generating some 850,000 pounds of thrust and fired for approximately the first four and a half minutes of flight. The Centaur upper stage was powered by the Aerojet Rocketdyne RL10C-1 engine.
The X-37B space plane was to separate from the Centaur about 19 minutes after liftoff. The Centaur continued firing separately with the CubeSat deployment, including the Planetary Society’s LightSail test demoonstration, into a different orbit later.
Overall this was ULA’s sixth launch of the 501 configuration the 54th mission to launch on an Atlas V rocket. This was also ULA’s fifth launch in 2015 and the 96th successful launch since the company was formed in December 2006.
The OTV is somewhat like a miniature version of NASA’s space shuttles.
Boeing has built two OTV vehicles. But it is not known which of the two vehicles was launched today.
Altogether the two X-37B vehicles have spent a cumulative total of 1367 days in space during the first three OTV missions and successfully checked out the vehicles reusable flight, reentry and landing technologies.
The 11,000 pound (4990 kg) state-of -the art reusable OTV space plane was built by Boeing and is about a quarter the size of a NASA space shuttle. It was originally developed by NASA but was transferred to the Defense Advanced Research Projects Agency (DARPA) in 2004.

All three OTV missions to date have launched from Cape Canaveral, Florida and landed at Vandenberg Air Force Base, California. Future missions could potentially land at the shuttle landing facility at the Kennedy Space Center, Florida.
The first OTV mission launched on April 22, 2010, and concluded on Dec. 3, 2010, after 224 days in orbit.
The following flights were progressively longer in duration. The second OTV mission began March 5, 2011, and concluded on June 16, 2012, after 468 days on orbit. The third OTV mission launched on Dec. 11, 2012 and landed on Oct. 17, 2014 after 674 days in orbit.
The vehicle measures 29 ft 3 in (8.9 m) in length with a wingspan of 14 ft 11 in (4.5 m). The payload bay measures 7 ft × 4 ft (2.1 m × 1.2 m). The space plane is powered by Gallium Arsenide Solar Cells with Lithium-Ion batteries.
Among the primary mission goals of the first three flights were check outs of the vehicles capabilities and reentry systems and testing the ability to send experiments to space and return them safely. OTV-4 will shift somewhat more to conducting research.
“We are excited about our fourth X-37B mission,” Randy Walden, director of the USAF’s Rapid Capabilities Office, said in a statement. “With the demonstrated success of the first three missions, we’re able to shift our focus from initial checkouts of the vehicle to testing of experimental payloads.”

Russia and its International Space Station (ISS) partners have prudently decided to postpone the scheduled upcoming crew rotations, involving departures and launches of station crews, in the wake of the failure of the Russian Progress 59 freighter that spun out of control soon after blastoff on April 28 and was destroyed during an uncontrolled plummet back to Earth on Friday, May 8.
The schedule shifting, whose possibility was reported here over the weekend and confirmed on Tuesday, May 12 by NASA and Roscosmos, literally came barely a day before the planned return to Earth on Wednesday, May 13 of the three person crew comprising of NASA astronaut and current station commander Terry Virts and flight engineers Samantha Cristoforetti of ESA (European Space Agency) and Anton Shkaplerov of Roscosmos. The trio have been working and living aboard the complex since November 2014.
The return of Virts, Cristoforetti and Shkaplerov is now targeted for early June, according to official statements from NASA, ESA and Roscosmos, the Russian space agency. That’s about a month later than the originally planned 171 day mission, in the wake of the failed Progress cargo ship that burned up on reentry.
Although an exact date has not been specified, sources indicate a tentative return target of around June 11.
“The partner agencies agreed to adjust the schedule after hearing the Russian Federal Space Agency’s (Roscosmos) preliminary findings on the recent loss of the Progress 59 cargo craft,” said NASA in a statement. “The exact dates have not yet been established, but will be announced in the coming weeks.”
If that new return date holds, ESA’s Samantha Cristoforetti will become the woman to fly the longest in space, eclipsing the current record holder, NASA astronaut Sunita Williams.

Blastoff of their replacement crew on the next planned manned Soyuz launch on May 26 from the Baikonur Cosmodrome in Kazakhstan has also been delayed, for about two months most likely to late July. That Expedition 44 crew comprises Russian cosmonaut Oleg Kononenko, Japanese astronaut Kimiya Yui and NASA astronaut Kjell Lindgren.
A rotating international crew of six astronauts and cosmonauts currently serve aboard the ISS. The delayed return of Virts crew from Expedition 43 will lessen the time when the ISS is staffed by a reduced crew of three, which significantly dampens the time allotted to science research.
A Russian state commission investigation board appointed by Roscosmos, is still seeking to determine the cause of the Progress 59 malfunction which occurred right around the time of the separation from its Soyuz-2.1A carrier rockets third stage following blastoff from the Baikonur space center in Kazakhstan.

A preliminary accident report from the state commission was planned for May 13. But investigators need more time to determine the root cause of the Progress 59 (also known as Progress M-27M) mishap.
Soon after detaching from the rockets third stage, it began to spin out of control at about 1.8 times per second, as seen in a video transmitted from the doomed ship.
NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka will remain aboard the station after the Virts crew returns to begin Expedition 44.
Roscosmos is also working to speed up the launch of the next unmanned Progress 60 (M-28M), potentially from August to early July. But that hinges on the outcome of the state commission investigation.

The 7 ton Progress vehicle was loaded with 2.5 tons of supplies for the ISS and the six person Expedition 43 crew. Items included personal mail for the crew, scientific equipment, food, water, oxygen, gear and replaceable parts for the station’s life support systems.
NASA officials say that the current ISS Expedition 43 six person crew is in no danger. The station has sufficient supplies to last until at least the fall of 2015, even if no other supplies arrive in the meantime.
Also in the mix is the launch of NASA’s next contracted unmanned Dragon cargo mission by commercial provider SpaceX on the CRS-7 flight. Dragon CRS-7 had been slated for liftoff no earlier than June 19. But that date could slip as well.
The Dragon will carry critical US equipment enabling docking by the SpaceX Crew Dragon and Boeing CST-100 astronaut transporters.

The spinning, out-of-control Russian Progress 59 cargo freighter met its undesired early demise when it fell from orbit early Friday, May 8, and was destroyed during the unplanned fiery plummet through the Earth’s atmosphere.
As a result of the loss of the unmanned Progress 59 spacecraft, which was bound for the International Space Station (ISS) on a routine resupply mission, the timelines of upcoming crew rotations and new launches are “under evaluation” – Universe Today learned according to Russian and American space sources.
The doomed Progress freighter “ceased to exist” after it reentered the Earth’s atmosphere 05.04 Moscow time on May 8, 2015 (10:04 p.m. EDT May 7) over the central Pacific Ocean,” according to an official statement from Roscosmos, the Russian Space Agency.
The consequences of the failure might cause “postponements of upcoming station crew changes to June” and blastoffs “to July” according to Russian space industry and media sources.
The vessel, also known as Progress M-27M, burned up minutes later and any surviving pieces fell over the Pacific Ocean.
“Debris fell about 900 kilometers west of the Marquesas Islands in the central Pacific Ocean,” a space industry source told the Russian news agency TASS.
“Roscosmos plans to adjust the program of flights to the International Space Station (ISS) due to the recent accident involving the Progress M-27M spacecraft,” according to the TASS rocket and space industry source.
Roscosmos quickly established an investigation board to determine the cause of the Progress failure and any commonalities it might have with manned launches of the Soyuz rocket and capsule, and report back by 13 May.
“The results of investigation of the incident related to “Progress M-27M” will be presented no later than 13 May following the completion of the state commission,” Roscosmos stated.
Russian mission controllers lost control of the Progress 59 spacecraft shortly after its otherwise successful launch to the ISS on April 28 from the Baikonur space center in Kazakhstan atop a Soyuz-2.1A carrier rocket.
Soon after detaching from the rockets third stage, it began to spin out of control at about 1.8 times per second, as seen in a video transmitted from the doomed ship.
After control could not be reestablished, all hope of docking with the ISS was abandoned by Roscosmos.
NASA officials said that the current ISS Expedition 43 six person crew is in no danger. The station has sufficient supplies to last until at least September, even if no other supplies arrive in the meantime.
“The spacecraft was not carrying any supplies critical for the United States Operating Segment (USOS) of the station, and the break up and reenty of the Progress posed no threat to the ISS crew,” NASA said in a statement.
“Both the Russian and USOS segments of the station continue to operate normally and are adequately supplied well beyond the next planned resupply flight.”
There is a stock of propellants onboard in the Russian segment that can be used for periodically required station reboosts.
According to TASS, “the cause of the accident with the Russian Progress M-27M spacecraft has not been established yet, Russian Deputy Prime Minister Dmitry Rogozin told journalists on Friday.”
“Not yet,” he said, answering a question on whether causes of the accident had been established.

Because the cause of Progress failure is not yet clear, the schedules for upcoming crew departures and launches to the ISS via Russian Soyuz rockets and capsules are “under evaluation,” according to sources.
There is a significant potential for a delay in the planned May 13 return to Earth of the three person crew international crew consisting of NASA astronaut and current station commander Terry Virts and flight engineers Samantha Cristoforetti of ESA (European Space Agency) and Anton Shkaplerov of Roscosmos, who have been aboard the complex since November 2014.
They comprise the current Expedition 43 crew, along with the recently arrived crew of NASA astronaut Scott Kelly and Russian cosmonauts Mikhail Kornienko and Gennady Padalka who launched onboard a Soyuz capsule on March 27.
Virts and his crewmates were due to head back to Earth in their Soyuz capsule on May 13. According to Russian sources, their return trip may be postponed to about June 11 to 13.
“The return from orbit of the expedition which is currently there is suggested to be postponed from May 14 to June,” said a TASS source.
Their three person replacement crew on Expedition 44 were due to blastoff on the next planned manned Soyuz launch on May 26 from the Baikonur Cosmodrome in Kazakhstan. This launch may now be delayed as well, to mid or late July.
“More time will be needed to check already manufactured rockets,” said a source. “A manned Soyuz launch may be made in the last ten days of July.”
“The proposal was forwarded by a Roscosmos working group and has not been approved yet,” reports TASS.
An official announcement by Roscosmos of any ISS schedule changes may come next week since the scheduled return of Virts crew is only days away.
Another potential change is that the launch of the next unmanned Progress 60 (M-28M), could potentially be moved up from August to July, hinging on the outcome of the state commission investigation.
To date flights of the Progress vehicle have been highly reliable. The last failure occurred in 2011, shortly after the retirement of NASA’s Space Shuttle orbiters in July 2011. The loss of the Progress did cascade into a subsequent crew launch delay later in 2011.

The next SpaceXFalcon 9 launch carrying the CRS-7 Dragon cargo ship on a resupply mission for NASA to the ISS is slated for mid-June. The most recent SpaceX Dragon was launched on the CRS-6 mission on April 14, 2015.
At this time the SpaceX CRS-7 launch remains targeted for liftoff on June 19, 2015.

Russia’s out-of-control Progress 59 cargo freighter is doomed to a fiery finale overnight Friday, May 8, according to Roscosmos, the Russian Space Agency.
The errant spaceship is expected to fall back to Earth and reenter the atmosphere early in the morning Moscow time following the latest orbital analysis by Roscosmos.
“The time window for the failed Progress spacecraft reentry in the Earth’s atmosphere was changed to a span between 01.13 a.m. and 04.51 a.m. Moscow time on May 8, according to Russia’s space agency Roscosmos,” according to the latest update today, May 7, from the Russian Sputnik news outlet.
According to a Roscosmos source, the unmanned Progress 59, also known as M-27M , would most likely make the atmospheric reentry over the Indian Ocean.
Roscosmos said in a statement that Progress 59 “will cease to exist” on Friday.
Most of the debris is expected to burn up. But any remaining fragments are likely to hit north of Madagascar.
Russian mission controllers lost control of the Progress 59 spacecraft ship – bound for the International Space Station (ISS) on a routine resupply mission – shortly after its otherwise successful launch on April 28 from the Baikonur space center in Kazakhstan atop a Soyuz-2.1A carrier rocket.
Soon after detaching from the rockets third stage, it began to spin out of control at about 1.8 times per second, as seen in a video transmitted from the doomed ship.
After control could not be reestablished, all hope of docking with the ISS was abandoned by Roscosmos.
Here’s a short video taken by the spinning Progress with NASA commentary:
The 7 ton vehicle was loaded with 2.5 tons of supplies for the ISS and the six person Expedition 43 crew. Items included personal mail for the crew, scientific equipment, as well as replaceable parts for the station’s life support systems and a stockpile of water and oxygen, according to Russia Today.
The Progress spacecraft is also loaded with a significant amount of fuel as it orbits Earth at an inclination of 51.6 degrees to the equator. This carries it over most of the populated world between 51.6 degrees north and south latitudes. But most of the area is over unpopulated oceans, making the chances of danger from falling debris very small.

To date the Progress vehicle have been highly reliable. The last failure occurred in 2011, shortly after the retirement of NASA’s Space Shuttle orbiters in July 2011.
Roscosmos has established an investigation board to determine the cause of the Progress failure and any commonalities it might have with manned launches of the Soyuz rocket and capsule.
“The conclusions are to be made by May 13, 2015,” according to a Roscosmos statement.
The potential exists for a delay in the next planned manned Soyuz launch with a three person international crew later on May 26 from the Baikonur Cosmodrome in Kazakhstan.
The ISS crew is in no danger and has sufficient supplies to last until at least September.
Besides the Russian Progress cargo ship, the ISS is resupplied by the commercial US SpaceX Dragon and Orbital Sciences Cygnus vessels and the Japanese HTV. ESA’s ATV has been retired after 5 flights.
The next Falcon 9 launch carrying the CRS-7 Dragon cargo ship on a resupply mission for NASA to the ISS is slated for mid-June. The most recent Dragon was launched on the CRS-6 mission on April 14, 2015.

Soaring on the power of an octet of SuperDrago engines, SpaceX successfully completed a critical rapid fire life-saving test of their Dragon crew capsules pad abort emergency escape system that would ignite in a split second to save the astronauts lives in the unlikely event of a failure of the Falcon 9 booster rocket at the Cape Canaveral launch pad.
The uncrewed SpaceX Crew Dragon roared swiftly skywards upon ignition of the test vehicle’s integrated SuperDraco engines at 9 a.m EDT this morning, Wednesday, May 6, for the mile high test conducted from the SpaceX Falcon 9 launch pad from a specially built platform at Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.
A human-sized crash test dummy was seated inside for the test exercise which ended safely with a parachute assisted Atlantic Ocean splashdown after less than two minutes. There were no astronauts aboard.
The SuperDraco engines fired for approximately six seconds and accelerated the crew Dragon “from 0 to 100 mph in 1.2 seconds. It reached a top speed of about 345 mph,” said SpaceX CEO Elon Musk in a post test briefing.
“This bodes quite well for the future of the program. I don’t want to jinx it, but this is really quite a good indication for the future of Dragon.” said Elon Musk.
“We hope to launch the first crews to the ISS within about two years, plus or minus six months.”
The side mounted escape engines mark a revolutionary change from the traditional top mounted launch escape system used previously in the Mercury, Apollo, Soyuz and Orion human spaceflight capsules. The space shuttle had no escape system beyond ejections seats used on the first four flights.
Dragon was mounted atop the finned trunk section for the test. The entire Dragon/trunk assembly was about 20 feet (5 meters) tall.
The test is a critical milestone towards the timely development of the human rated Dragon that NASA is counting on to restore the US capability to launch astronauts from US soil abroad US rockets to the International Space Station (ISS) as early as 2017.
“This is a critical step toward ensuring crew safety for government and commercial endeavors in low-Earth orbit,” said Kathy Lueders, manager of NASA’s Commercial Crew Program.
“Congratulations to SpaceX on what appears to have been a successful test on the company’s road toward achieving NASA certification of the Crew Dragon spacecraft for missions to and from the International Space Station.”
Here is a video of the Pad Abort Test:

After all the monomethylhydrazine and nitrogen tetroxide hypergolic propellants were consumed, Dragon soared as planned to an altitude of about 1500 meters (.93 mi) above the launch pad. At about T+21 seconds the trunk was jettisoned and the spacecraft began a slow rotation with its heat shield pointed toward the ground again as it arced out eastwards over the ocean.
The drogue chutes and trio of red and white main parachutes deployed as planned for a picturesque Dragon splashdown in the Atlantic Ocean about a mile offshore of its Cape Canaveral launch pad. The capsule was retrieved from the ocean by waiting recovery boats.
Today’s pad abort demonstration tested the ability of the set of eight SuperDraco engines integrated directly into the side walls of the crew Dragon to ignite simultaneously and pull the vehicle away from the launch pad in a split second – in a simulated emergency to save the astronauts lives in the event of a real emergency.
Therefore the Pad Abort Test did not include an actual Falcon 9 booster since it was focused on a checkout of the capsule’s escape capability.

The SuperDraco engines are located in four jet packs built into the capsule around the base. Each engine produces about 15,000 pounds of thrust pounds of axial thrust, for a combined total thrust of about 120,000 pounds in under one second, to propel the astronauts safely away.
The entire test lasted less than two minutes.
The test was webcast live on NASA TV: http://www.nasa.gov/nasatv
The crew Dragon is outfitted with 270 sensors to measure a wide range of vehicle, engine, acceleration and abort test parameters.
The pad abort test was accomplished under SpaceX’s Commercial Crew Integrated Capability (CCiCap) agreement with NASA, that will eventually lead to certification of the Dragon for crewed missions to low Earth orbit and the ISS.
A second Dragon flight test follows later in the year, perhaps in the summer. It will launch from a SpaceX pad at Vandenberg Air Force Base in California and involves simulating an in flight emergency abort scenario during ascent at high altitude at maximum aerodynamic pressure (Max-Q) at about T plus 1 minute, to save astronauts lives.
The pusher abort thrusters would propel the capsule and crew safely away from a failing Falcon 9 booster for a parachute assisted splashdown into the ocean.
“This is what SpaceX was basically founded for, human spaceflight,” said Hans Koenigsmann, vice president of Mission Assurance with SpaceX, at a prelaunch briefing.
“The pad abort is going to show that we’ve developed a revolutionary system for the safety of the astronauts, and this test is going to show how it works. It’s our first big test on the Crew Dragon.”

The test flight – called the Pad Abort Test – is slated for the early morning hours of Wednesday, May 6, if all goes well. The key facts and a timeline of the test events are outlined herein.
The test vehicle will reach roughly a mile in altitude (5000 feet, 1500 meters) and last only about 90 seconds in duration from beginning to end.
It constitutes a crucial first test of the crew capsule escape system that will save astronauts lives in a split second in the unlikely event of a catastrophic launch pad failure with the Falcon 9 rocket.
The May 6 pad abort test will be performed from the SpaceX Falcon 9 launch pad from a platform at Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The test will not include an actual Falcon 9 booster.
SpaceX has just released new images showing the Dragon crew capsule and trunk section being moved to the launch pad and being positioned atop the launch mount on SLC-40. See above and below. Together the Dragon assembly stands about 20 feet (5 meters) tall.

A test dummy is seated inside. And SpaceX now says the dummy is not named “Buster” despite an earlier announcement from the company.
“Buster the Dummy already works for a great show you may have heard of called MythBusters. Our dummy prefers to remain anonymous for the time being,” SpaceX said today.
So, only time will tell if that particular mission fact will ever be revealed.
The test window opens at 7 a.m. EDT May 6 and extends until 2:30 p.m. EDT into the afternoon.
The webcast will start about 20 minutes prior to the opening of the window. NASA will also provide periodic updates about the test at their online Commercial Crew Blog.
The current weather forecast predicts a 70% GO for favorable weather conditions during the lengthy test window.
Since the Pad Abort Test is specifically designed to be a development test, in order to learn crucial things about the performance of the escape system, it doesn’t have to be perfect to be valuable.
And delays due to technical issues are a very significant possibility.
“No matter what happens on test day, SpaceX is going to learn a lot,” said Jon Cowart, NASA’s partner manager for SpaceX at a May 1 media briefing at the Kennedy Space Center press site. “One test is worth a thousand good analyses.”
The test is critical for the timely development of the human rated Dragon that NASA is counting on to restore the US capability to launch astronauts from US soil abroad US rockets to the International Space Station (ISS) as early as 2017.

The Crew Dragon will accelerate to nearly 100 mph in barely one second. The test will last less than two minutes and the ship will travel over one mile in the first 20 seconds alone.
The pad abort demonstration will test the ability of a set of eight SuperDraco engines built into the side walls of the crew Dragon to pull the vehicle away from the launch pad in a split second in a simulated emergency to save the astronauts lives in the event of a real emergency.
The SuperDraco engines are located in four jet packs around the base. Each engine produces about 15,000 pounds of thrust pounds of axial thrust, for a combined total thrust of about 120,000 pounds, to carry astronauts to safety.
The eight SuperDraco’s will propel Dragon nearly 100 meters (328 ft) in 2 seconds, and more than half a kilometer (1/3 mi) in just over 5 seconds.
SpaceX likens the test to “an ejection seat for a fighter pilot, but instead of ejecting the pilot out of the spacecraft, the entire spacecraft is “ejected” away from the launch vehicle.”
Here’s a timeline of events from SpaceX:
T-0: The eight SuperDracos ignite simultaneously and reach maximum thrust, propelling the spacecraft off the pad.
T+.5s: After half a second of vertical flight, Crew Dragon pitches toward the ocean and continues its controlled burn. The SuperDraco engines throttle to control the trajectory based on real-time measurements from the vehicle’s sensors.
T+5s: The abort burn is terminated once all propellant is consumed and Dragon coasts for just over 15 seconds to its highest point about 1500 meters (.93 mi) above the launch pad.
T+21s: The trunk is jettisoned and the spacecraft begins a slow rotation with its heat shield pointed toward the ground again.
T+25s: Small parachutes, called drogues, are deployed first during a 4-6 second window following trunk separation.
T+35s: Once the drogue parachutes stabilize the vehicle, three main parachutes deploy and further slow the spacecraft before splashdown.
T+107s: Dragon splashes down in the Atlantic Ocean about 2200 meters (1.4 mi) downrange of the launch pad.

“This is what SpaceX was basically founded for, human spaceflight,” said Hans Koenigsmann, vice president of Mission Assurance with SpaceX.
“The pad abort is going to show that we’ve developed a revolutionary system for the safety of the astronauts, and this test is going to show how it works. It’s our first big test on the Crew Dragon.”
The pusher abort thrusters would propel the capsule and crew safely away from a failing Falcon 9 booster for a parachute assisted splashdown into the Ocean.
Koenigsmann notes that the SpaceX abort system provides for emergency escape all the way to orbit, unlike any prior escape system such as the conventional launch abort systems (LAS) mounted on top of the capsule.
The next Falcon 9 launch is slated for mid-June carrying the CRS-7 Dragon cargo ship on a resupply mission for NASA to the ISS. On April 14, a flawless Falcon 9 launch boosted the SpaceX CRS-6 Dragon to the ISS.
There was no attempt to soft land the Falcon 9 first stage during the most recent launch on April 27. Due to the heavy weight of the TurkmenÄlem52E/MonacoSat satellite there was not enough residual fuel for a landing attempt on SpaceX’s ocean going barge.
The next landing attempt is set for the CRS-7 mission.

SpaceX and NASA are just days away from a crucial test of a crew capsule escape system that will save astronauts lives in the unlikely event of a launch failure with the Falcon 9 rocket.
Buster the Dummy is already strapped into his seat aboard the SpaceX Crew Dragon test vehicle for what is called the Pad Abort Test, that is currently slated for Wednesday, May 6.
The test is critical for the timely development of the human rated Dragon that NASA is counting on to restore the US capability to launch astronauts from US soil abroad US rockets to the International Space Station (ISS) as early as 2017.
Boeing was also selected by NASA to build the CST-100 spaceship to provide a second, independent crew space taxi capability to the ISS during 2017.
The May 6 pad abort test will be performed from the SpaceX Falcon 9 launch pad from a platform at Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The test will not include an actual Falcon 9 booster.

The SpaceX Dragon and trunk together stand about 20 feet tall and are positioned atop the launch mount at SLC-40 for what is clearly labeled as a development test to learn how the Dragon, engines and abort system perform.
Buster will soar along inside the Dragon that will be rapidly propelled to nearly a mile high height solely under the power of eight SpaceX SuperDraco engines.
The trunk will then separate, parachutes will be deployed and the capsule will splashdown about a mile offshore from Florida in the Atlantic Ocean, said Hans Koenigsmann, vice president of Mission Assurance at SpaceX during a May 1, 2015 press briefing on the pad abort test at the Kennedy Space Center, Florida.
The entire test will take about a minute and a half and recovery teams will retrieve Dragon from the ocean and bring it back on shore for detailed analysis.
The test will be broadcast live on NASA TV. The test window opens at 7 a.m. EDT May 6 and extends until 2:30 p.m. EDT. The webcast will start about 20 minutes prior to the opening of the window. NASA will also provide periodic updates about the test at their online Commercial Crew Blog.

The test is designed to simulate an emergency escape abort scenario from the test stand at the launch pad in the unlikely case of booster failing at liftoff or other scenario that would threaten astronauts inside the spacecraft.
The pad abort demonstration will test the ability of a set of eight SuperDraco engines built into the side walls of the crew Dragon to pull the vehicle away from the launch pad in a split second in a simulated emergency to save the astronauts lives in the event of a real emergency.
The SuperDraco engines are located in four jet packs around the base. Each engine produces about 15,000 pounds of thrust pounds of axial thrust, for a combined total thrust of about 120,000 pounds, to carry astronauts to safety, according to Koenigsmann.
“This is what SpaceX was basically founded for, human spaceflight,” said Hans Koenigsmann, vice president of Mission Assurance with SpaceX.
“The pad abort is going to show that we’ve developed a revolutionary system for the safety of the astronauts, and this test is going to show how it works. It’s our first big test on the Crew Dragon.”
SpaceX and NASA hope to refurbish and reuse the same Dragon capsule for another abort test at high altitude later this year. The timing of the in flight abort test hinges on the outcome of the pad abort test.
“No matter what happens on test day, SpaceX is going to learn a lot,” said Jon Cowart, NASA’s partner manager for SpaceX. “One test is worth a thousand good analyses.”

Beside Buster the dummy, who is human-sized, the Dragon is outfitted with 270 sensors to measure a wide range of vehicle, engine, acceleration and abort test parameters.
“There’s a lot of instrumentation on this flight – a lot,” Koenigsmann said. “Temperature sensors on the outside, acoustic sensors, microphones. This is basically a flying instrumentation deck. At the end of the day, that’s the point of tests, to get lots of data.”
Buster will be accelerated to a force of about 4 to 4½ times the force of Earth’s gravity, noted Koenigsmann.
The pad abort test is being done under SpaceX’s Commercial Crew Integrated Capability (CCiCap) agreement with NASA that will eventually lead to certification of the Dragon for crewed missions to low Earth orbit and the ISS.
“The point is to gather data – you don’t have to have a flawless test to be successful,” Cowart said.
The second Dragon flight test follows later in the year, perhaps in the summer. It will launch from a SpaceX pad at Vandenberg Air Force Base in California and involves simulating an in flight emergency abort scenario during ascent at high altitude at maximum aerodynamic pressure (Max-Q) at about T plus 1 minute, to save astronauts lives.

Koenigsmann notes that the SpaceX abort system provides for emergency escape all the way to orbit, unlike any prior escape system such as the conventional launch abort systems (LAS) mounted on top of the capsule.
“Whatever happens to Falcon 9, you will be able to pull out the astronauts and land them safely on this crew Dragon,” said Koenigsmann. “In my opinion, this will make it the safest vehicle that you can possibly fly.”
The SpaceX Dragon V2 and Boeing CST-100 vehicles were selected by NASA last fall for further funding under the auspices of the agency’s Commercial Crew Program (CCP), as the worlds privately developed spaceships to ferry astronauts back and forth to the International Space Station (ISS).
Both SpaceX and Boeing plan to launch the first manned test flights to the ISS with their respective transports in 2017.
During the Sept. 16, 2014 news briefing at the Kennedy Space Center, NASA Administrator Charles Bolden announced that contracts worth a total of $6.8 Billion were awarded to SpaceX to build the manned Dragon V2 and to Boeing to build the manned CST-100.
The next Falcon 9 launch is slated for mid-June carrying the CRS-7 Dragon cargo ship on a resupply mission for NASA to the ISS. On April 14, a flawless Falcon 9 launch boosted the SpaceX CRS-6 Dragon to the ISS.

SpaceX set a new internal record pace for time between blastoffs of their workhorse Falcon 9 rocket with Monday’s spectacular dusky liftoff of Turkmenistan’s first satellite into heavily overcast skies that has cleared the path ahead for a busy manifest of critical flights starting with a critical pad abort test for NASA just a week from today.
After a 49 minute delay due to grim weather conditions, weather officials finally found a “window in the clouds” that permitted the Falcon 9 to launch on Monday, April 27, 2015 at 7:03pm EDT (2303 GMT).
The launch took place just 13 days after successfully launching the SpaceX Dragon CRS-6 resupply freighter to the International Space Station (ISS) for NASA on April 14.
Overall this launch marked Falcon 9’s fifth launch in four months and second in 13 days, besting SpaceX’s previous turnaround record by one day.
But it was touch and go all afternoon, when two weather rules related to cloudy conditions violated the launch commit criteria and forced a no go from the originally planned 6:14 liftoff time.
The situation was not at all promising when the weather officer announced “NO GO” during the prelaunch poll that resulted in a recycle to the T minus 20 minute mark with seemingly little prospect of a launch. Then all of a sudden, conditions improved and the count was resumed and “wet off without a hitch” said SpaceX.

The 14 story Falcon 9 first stage is powered by 9 Merlin 1D engines that generate about 1.3 million pounds of thrust.
The Falcon 9’s first and second stages separated three minutes after launch. The second stage fired for six minutes for its first burn to reach the initial parking orbit. It then reignited twenty-six minutes into flight, to completed a one-minute burn.

The launch delivered the 10,375-pound (4500 kg) TurkmenÄlem52E/MonacoSat satellite to a geosynchronous transfer orbit. The satellite was deployed as planned approximately 32 minutes after liftoff.
Launches are never easy, as exemplified by a post launch tweet from SpaceX CEO Elon Musk after the satellite was deployed from the second stage.
‘Rocket launch good, satellite in geo transfer orbit. Still so damn intense. Looking fwd to it feeling normal one day,” tweeted Musk.
Despite the launch of Turkmenistan’s first communications satellite, the country is conducting a war on satellite dishes to receive the signals according to Human Rights Watch.
“Authorities in Turkmenistan are forcing residents to dismantle privately owned satellite dishes,” Human Rights Watch said in a statement on April 24. “A move that unjustifiably interferes with the right to receive and impart information and ideas, this serves to further isolate people in Turkmenistan, one of the most closed and repressive countries in the world, from independent sources of news and information.”

Just 1 week from today on May 5, SpaceX plans a pad abort test for NASA that is critical for the timely development of the human rated Dragon that NASA is counting on to restore the US capability to launch astronauts from US soil to the space station.
The next Falcon 9 launch is slated for mid-June carrying the CRS-7 Dragon cargo ship on a NASA mission to the ISS.
