SpaceX is targeting a June 1 blastoff for the firms next cargo delivery mission to the International Space Station (ISS) for NASA following today’s (May 28) successful test firing of the Falcon 9 booster’s main engines on the Florida Space Coast under sunny skies.

Liftoff of the SpaceX Falcon 9 rocket carrying the unmanned Dragon cargo freighter from seaside pad 39A at NASA’s Kennedy Space Center in Florida is slated for 5:55 p.m. EDT Thursday, June 1.

“Static fire test of Falcon 9 complete,” SpaceX confirmed via Twitter soon after completion of the test at noon today 12 p.m. EDT.

“Targeting June 1 launch from historic Pad 39A for Dragon’s next resupply mission to the @Space_Station.”

The static fire test also apparently set off a brush fire near the pad which required a response from firefighters to douse the blaze with water bucket drops from helicopters.

“#USFWS firefighters are responding to a new wildfire at Merritt Island NWR caused by a static rocket test fire #FLfire,” tweeted the US Fish and Wildlife Service.

The wildfire stretched to 4 acres on Merritt Island and was successfully contained, the US Fish and Wildlife Service said.

With the launch conveniently coinciding with dinnertime, it will offer prime time viewing thrills for spectators and space enthusiasts coming from near and far.

The weather outlook for Thursday is currently promising with mostly sunny conditions but can change at a moments notice.

And to top that off SpaceX will attempt a land landing of the first stage back at the Cape at Landing Zone 1 some 9 minutes after liftoff.

The Dragon resupply ship dubbed Dragon CRS-11 counts as SpaceX’s eleventh contracted commercial resupply services (CRS) mission to the International Space Station for NASA since 2012.

It is carrying almost 6,000 pounds of science research, crew supplies and hardware to the orbiting laboratory in support of Expedition 52 and 53 crew members. The unpressurized trunk of the spacecraft also will transport solar panels, tools for Earth-observation and equipment to study neutron stars.

Dragon CRS-11 will be the second SpaceX resupply mission to launch this year.

The prior SpaceX cargo ship launched on Feb 19, 2017 on the CRS-10 mission to the space station. It was also the first SpaceX launch of a Falcon 9 from NASA’s historic pad 39A.

Another significant milestone for this flight is that it features the first reuse of a previously launched Dragon. It previously launched on the CRS-4 resupply mission.

Sunday’s brief static fire test involved a successful hot fire ignition test of the two stage rocket and all nine first stage Merlin 1D engines Sunday afternoon while the rocket was firmly held down at the pad.

The hold down engine test is routinely conducted to confirm the readiness of the engines and rocket for flight.

The nine Merlin 1D engines generate 1.7 million pounds of thrust for approximately three seconds.

The test simulates all the conditions of flight except liftoff, and involves loading of the densified liquid oxygen and RP-1 propellants into the first and second stages starting about 70 minutes prior to ignition.

The engine test was run without the Dragon cargo ship bolted on top.

The rocket was rolled out of the SpaceX processing hangar at the perimeter fence early this morning and then up the slight incline to the top of pad 39A. It was erected vertical to launch position using a dedicated transporter-erector.

With the successful completion of the static fire test, the booster will be rolled back to the big processing hangar and Dragon CRS-11 will be integrated on top.

NASA will offer live launch coverage on NASA Television and the agency’s website at beginning 5:15 p.m. on June 1.

In case of a delay for any reason, the next launch opportunity is 5:07 p.m. Saturday, June 3, with NASA TV coverage starting at 4:30 p.m.

SpaceX Dragon Splashes Down in Pacific with Treasure Trove of Space Station Science

KENNEDY SPACE CENTER, FL – SpaceX’s tenth contracted resupply mission to the International Space Station came to a safe conclusion with a splashdown of the Dragon spacecraft in the Pacific Ocean Sunday and successfully returned a treasure trove of more than two tons of precious science experiments and research samples from the space station.

Researchers on Earth are eagerly awaiting the science data and samples in order to carry out high powered laboratory analysis that will eventually yield the fruits of the hard won labor – years in the making.

The Dragon CRS-10 cargo freighter departed the International Space Station (ISS) Sunday morning after Expedition 50 astronauts Thomas Pesquet of ESA (European Space Agency) and Shane Kimbrough of NASA released the spacecraft from the grip of the station’s 57.7-foot-long(17.6-meter) Canadian-built Canadarm2 robotic arm as planned at 5:11 a.m. EDT, March 19.

After carefully maneuvering away from the orbiting outpost and six person international crew at an altitude of appox. 250 miles (400 km), Dragon eased away to a safe distance.

The vessel then fired its braking thrusters a few hours later to initiate the reentry burn that would set the craft on course for a fiery plummet through the Earth’s atmosphere.

Some five and a half hours later the spaceship carried out a parachute assisted splashdown in the Pacific Ocean at 10:46 a.m. EDT, about 200 miles southwest of Long Beach, California.

The highest priority research and technology cargo will be removed from Dragon immediately and returned to NASA.

The rest will travel back to port and be prepared for a return trip to SpaceX’s test facility in McGregor, Texas, where the remaining scientific samples, research experiments and technology gear and hardware will be unloaded for NASA.

Dragon had spent nearly a month berthed at the Earth-facing port on the station’s Harmony module, since arriving on Feb 23.

Dragon begun its space voyage after it was launched from the Kennedy Space Center (KSC) on Sunday, Feb. 19 on the first Falcon 9 rocket ever to blast off from historic launch pad 39A in a blaze of glory – as I reported here.

At liftoff, the Dragon CRS-10 space freighter was carrying more than 5500 pounds of equipment, gear, food, crew supplies, hardware and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload to the low Earth orbiting station in support of the Expedition 50 and 51 crew members.

After a four day chase, Dragon was captured and attached to the station using the Canadian arm on Feb 23 by the same two astronauts who released it on Sunday.

The research supplies and equipment brought up by Dragon will support over 250 scientific investigations to advance knowledge about the medical, psychological and biomedical challenges astronauts face during long-duration spaceflight.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere. It is one of NASA’s longest running earth science programs.

The LIS lightning mapper will measure the amount, rate and energy of lightning as it strikes around the world from the altitude of the ISS as it orbits Earth. Its data will complement that from the recently orbited GLM lighting mapper lofted to geosynchronous aboard the NASA/NOAA GOES-R spacecraft instrument.

NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

SAGE III and RAVEN were stowed in the Dragon’s unpressurized truck. Astronauts plucked them out of the trunk using the robotic arm and attached them to specified locations on the stations exterior to carry out their objectives.

For the return trip to Earth, the astronaut crew loaded Dragon with more than 5,400 pounds of NASA cargo, and science and technology demonstration samples gathered and collected by the stations crewmembers.

“A variety of technological and biological studies are returning in Dragon. The Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity,” said NASA.

“This information will provide insight into how human cancers start and spread, which aids in the development of prevention and treatment plans. Results from this investigation could lead to the treatment of disease and injury in space, as well as provide a way to improve stem cell production for human therapy on Earth.”

“Samples from the Tissue Regeneration-Bone Defect study, a U.S. National Laboratory investigation sponsored by the Center for the Advancement of Science in Space (CASIS) and the U.S. Army Medical Research and Materiel Command, studied what prevents vertebrates such as rodents and humans from re-growing lost bone and tissue, and how microgravity conditions affect the process. Results will provide a new understanding of the biological reasons behind a human’s inability to grow a lost limb at the wound site, and could lead to new treatment options for the more than 30 percent of the patient population who do not respond to current options for chronic non-healing wounds.”

Dragon departed in order to make way for the arrival of the next cargo ship.
