KENNEDY SPACE CENTER, FL – July has begun with SpaceX maintaining a blistering pace of blasting rockets and spaceships flying to space and returning to Earth for a host of multipronged missions furthering NASA science both on the International Space Station (ISS) and beyond, commercial space endeavors in the US and overseas and fulfilling billionaire founder Elon Musk’s dreams of creating reusable rocketry to slash launch costs and advance humanity’s push to the stars.

On July 2, SpaceX conducted the first launch attempt of the Intelsat 35e telecomsat that ultimately culminated with a spectacularly successful launch on the third try on July 5 at dusk that lit up the Florida Space Coast skies.

A Falcon 9 roared off SpaceX’s seaside launch pad 39A at NASA’s Kennedy Space Center in Florida precisely on time at 7:38 p.m. EDT, or 2338 UTC July 5 carrying the massive Intelsat 35e communications satellite for commercial high speed broadband provider Intelsat.

The Dragon CRS-11 spacecraft completed the first re-flight mission of a commercial spacecraft to and from the orbiting laboratory.

The gumdrop shaped Dragon spacecrft brought back more than 4,100 pounds of cargo and research samples gathered by members of the stations multinational crews.

Meanwhile, the doubly ‘flight-proven’ SpaceX Falcon 9 booster from the BulgariaSat-1 launch that propulsoively soft landed upright and intact on the sea going OCISLY drone ship hundreds of mile (km) offshore in the Atlantic Ocean sailed back into Port Canaveral.

After berthing in port, technicians removed its quartet of landing legs and lowered it horizontally for transport back to KSC for refurbishment operations.

KENNEDY SPACE CENTER, FL – The first ever reused Dragon supply ship successfully arrived at the International Space Station (ISS) two days after a thunderous liftoff from NASA’s Kennedy Space Center atop a SpaceX Falcon 9 rocket on Saturday, June 3. The first stage booster made a magnificent return to the Cape and erect ground landing some 8 minutes after liftoff.

Meanwhile the already berthed Orbital ATK Cygnus OA-7 supply ship departed the station on Sunday, June 4 after ground controllers detached it and maneuvered it into position for departure.

The commercial Dragon cargo freighter carrying nearly 3 tons of science and supplies for the multinational crew on the CRS-11 resupply mission reached the space stations vicinity Monday morning, June 5, after a two day orbital chase starting from the Kennedy Space Center and a flawless series of carefully choreographed thruster firings culminated in rendezvous.

Liftoff of the SpaceX Falcon 9 rocket carrying the unmanned Dragon cargo freighter from seaside Launch Complex 39A at KSC in Florida took place during an instantaneous launch window at 5:07 p.m. EDT Saturday, June 3, following a 48 hour delay due to a stormy weather scrub at the Florida Space Coast on Thursday, June 1.

The stunning Falcon 9 launch and landing events were captured by journalists and tourists gathered from around the globe to witness history in the making with their own eyeballs.

The Falcon 9 blastoff also counts as the 100th flight from KSC’s historic pad 39A which previously launched NASA’s Apollo astronauts on lunar landing missions and space shuttles for 3 decades

By 8:30 a.m. Monday morning ground controllers had maneuvered Dragon to within 250 meters of the station and the imaginary keep out sphere around the orbiting complex.

Engineers carefully assessed the health of the Dragon and its systems to insure its ability to slowly and safely move in closer for capture by the crew.

When Dragon reached a distance of 11 meters, it was grappled by Expedition 52 astronauts Peggy Whitson and Jack Fischer using the 57.7 foot long (17.6 meter long) Canadian-built robotic arm Monday morning at 9:52 a.m. EDT, a few minutes ahead of schedule.

“Capture complete,” radioed Whitson as Dragon was captured at its grapple pin by the grappling snares at the terminus of the Canadarm2 robotic arm.

Dragon’s capture took place as the ISS was orbiting 250 miles over the South Atlantic Ocean as it was nearing the East coast of Argentina.

“Complete complete. Go for capture configuration,” replied Houston Mission control.

“We want to thank the entire team on the ground that made this possible, both in Hawthorne and in Houston. Really around the whole world, from support in Canada for this wonderful robotic arm, Kennedy Space Center’s launch support, to countless organizations which prepared the experiments and cargo,” Fischer radioed in response.

“These people have supplied us with a vast amount of science and supplies, really fuel for the engine of innovation we get to call home, the International Space Station. We have a new generation of vehicles now, led by commercial partners like SpaceX, as they build the infrastructure that will carry us into the future of exploration.”

“It’s also the first second mission to the ISS which was previously here as CRS-4. The last returned visitor was space shuttle Atlantis on the STS-135 mission,” Fischer said.

A little over two hours after it was captured by Expedition 52 Flight Engineers Jack Fischer and Peggy Whitson, ground teams maneuvered the unpiloted SpaceX Dragon cargo craft for attachment to the Earth-facing port of the station’s Harmony module.

“Ground controllers at Mission Control, Houston reported that Dragon was bolted into place at 12:07 p.m. EDT as the station flew 258 statute miles over central Kazakhstan,” NASA reported.

The berthing of Dragon to Harmony was not broadcast live on NASA TV.

The CRS-11 cargo ship will support over 62 of the 250 active research investigations and experiments being conducted by Expedition 52 and 53 crew members.

The flight delivered investigations and facilities that study neutron stars, osteoporosis, solar panels, tools for Earth-observation, and more.

40 new micestonauts are also aboard inside the rodent research habitat for a first of its kind osteoporosis science study – that seeks to stem the loss of bone density afflicting millions of people on Earth and astronauts crews in space by testing an experimental drug called NELL-1. The therapy will also examine whether bone can be regenerated for the first time. No drug exists for bone regeneration.

The unpressurized trunk of the Dragon spacecraft also transported 3 payloads for science and technology experiments and demonstrations.

The truck payloads include the Roll-Out Solar Array (ROSA) solar panels, the Multiple User System for Earth Sensing (MUSES) facility which hosts Earth-viewing instruments and tools for Earth-observation and equipment to study neutron stars with the Neutron Star Interior Composition Explorer (NICER) payload.

NICER is the first ever space mission to study the rapidly spinning neutron stars – the densest objects in the universe. The launch coincidentally comes nearly 50 years after they were discovered by British astrophysicist Jocelyn Bell.

A second objective of NICER involves the first space test attempting to use pulsars as navigation beacons through technology called Station Explorer for X-Ray Timing and Navigation (SEXTANT).

NASA decided to use the SpaceX weather related launch delay to move up the departure of the “SS John Glenn” Cygnus cargo ship by over a month since it was already fully loaded and had completed its mission to deliver approximately 7,600 pounds of supplies and science experiments to the orbiting laboratory and its Expedition 51 and 52 crew members for Orbital ATK’s seventh NASA-contracted commercial resupply mission called OA-7.

Named after legendary Mercury and shuttle astronaut John Glenn – 1st American to orbit the Earth – the supply ship had spent 44 days at the station.

The “SS John Glenn” will now remain in orbit a week to conduct the third SAFFIRE fire experiment as well as deploy four small Nanoracks satellites before Orbital ATK flight controllers send commands June 11 to deorbit the spacecraft for its destructive reentry into the Earth’s atmosphere over the Pacific Ocean.

KENNEDY SPACE CENTER, FL – After threatening stormy skies over the Florida Space Coast miraculously parted just in the nick of time, the first ever recycled SpaceX Dragon cargo freighter blasted off on the 100th flight from historic pad 39A on the Kennedy Space Center (KSC) late Saturday afternoon June 3 – bound for the International Space Station (ISS) loaded with a science rich cargo from NASA for the multinational crew.

Nearly simultaneously the first stage booster accomplished another heart stopping and stupendous ground landing back at the Cape accompanied by multiple shockingly loud sonic booms screeching out dozens of miles (km) in all directions across the space coast region.

Liftoff of the SpaceX Falcon 9 rocket carrying the unmanned Dragon cargo freighter from seaside Launch Complex 39A at KSC in Florida took place during an instantaneous launch window at 5:07 p.m. EDT Saturday, June 3, after a predicted downpour held off just long enough for the SpaceX launch team to get the rocket safely off the ground.

The launch took place after a 48 hour scrub from Thursday June 1 forced by stormy weather and lightning strikes came within 10 miles of pad 39A less than 30 minutes from the planned liftoff time.

The backup crew of 40 new micestonauts are also aboard for a first of its kind osteoporosis science study – that seeks to stem the loss of bone density afflicting millions of people on Earth and astronauts crews in space by testing an experimental drug called NELL-1. The 40 originally designated mice lost their coveted slot and were swapped out Friday due to the scrub.

The 213-foot-tall (65-meter-tall) SpaceX Falcon 9 roared to life off pad 39A upon ignition of the 9 Merlin 1 D first stage engines generating 1.7 million pounds of liftoff thrust and successfully delivered the Dragon bolted on top to low Earth orbit on course for the space station and jam packed with three tons of essential cargo.

Loading of the densified liquid oxygen and RP-1 propellants into the Falcon 9 first and second stages starting about 70 minutes prior to ignition. Everything went off without a hitch.

Dragon reached its preliminary orbit 10 minutes after launch and deployed its power generating solar arrays. It now set out on a carefully choreographed series of thruster firings to reach the space station Monday morning.

Following stage separation at 2 min 25 sec after liftoff, the first stage began a series of three burns (boostback, entry and landing) to carry out a precision propulsive ground landing back at Cape Canaveral Air Force Station, FL at Landing Zone-1 (LZ-1).

Thus overall SpaceX has now successfully recovered 11 boosters; 5 by land and 6 by sea, over the past 18 months – in a feat straight out of science fiction but aimed at drastically slashing the cost of access to space as envisioned by SpaceX billionaire CEO and founder Elon Musk.

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.

The recycled Dragon has undergone some refurbishments to requalify it for flight but most of the structure is intact, according to SpaceX VP for Mission Assurance Hans Koenigsmann.

The 20-foot high, 12-foot-diameter Dragon is carrying almost 5,970 pounds of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex. This will support over 62 of the 250 research investigations and experiments being conducted by Expedition 52 and 53 crew members.

Dragon is loaded with “major experiments that will look into the human body and out into the galaxy.”

The flight will deliver investigations and facilities that study neutron stars, osteoporosis, solar panels, tools for Earth-observation, and more.

The unpressurized trunk of the spacecraft also will transport 3 payloads for science and technology experiments and demonstrations.

The truck payloads include the Roll-Out Solar Array (ROSA) solar panels, the Multiple User System for Earth Sensing (MUSES) facility which hosts Earth-viewing instruments and tools for Earth-observation and equipment to study neutron stars with the Neutron Star Interior Composition Explorer (NICER) payload.

If all goes well, Dragon will arrive at the ISS 2 days after launch and be grappled by Expedition 52 astronauts Peggy Whitson and Jack Fischer using the 57.7 foot long (17.6 meter long) Canadian-built robotic arm.

They will berth Dragon at the Earth-facing port of the Harmony module.

NASA TV will begin covering the Dragon rendezvous and grappling activities starting at 8:30 a.m. Monday.

Dragon CRS-11 is SpaceX’s second contracted resupply mission to launch this year for NASA.

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

Overall CRS-11 marks the 100th launch from pad 39A and the sixth SpaceX launch from this pad.

SpaceX leased pad 39A from NASA in 2014 and after refurbishments placed the pad back in service this year for the first time since the retirement of the space shuttles in 2011. To date this is the sixth SpaceX launch from this pad.

Previous launches include 11 Apollo flights, the launch of the unmanned Skylab in 1973, 82 shuttle flights and five SpaceX launches.

KENNEDY SPACE CENTER, FL – The 100th blastoff from NASA’s historic pad 39A features a SpaceX Dragon resupply mission carrying three tons of science and crew supplies to the International Space Station (ISS) as well as another unfathomable ground landing of the Falcon 9 rockets first stage. UPDATE: Stormy weather and lightning scrubs launch until Saturday, June 3 at 5:07 p.m. EDT

40 micetonauts are also aboard for a first of its kind osteoporosis science study – that seeks to stem the loss of bone density afflicting millions of people on Earth and astronauts crews in space by testing an experimental drug called NELL-1. Update: The rocket was lowered into horizontal position in order to swap out the 40 micetonauts and other time critial cargo items.

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.

Everything is on track for Thursday’s dinnertime launch of the 230 foot tall SpaceX Falcon 9 on the NASA contracted SpaceX CRS-11 resupply mission to the million pound orbiting lab complex.

However since the launch window is instantaneous there is no margin. In case any delays arise during the countdown due to technical or weather issues a 48 hour scrub to Saturday will result.

The launch is coincidently scheduled for dinnertime offering a spectacular opportunity for fun for the whole family as space enthusiasts flock in from around the globe.

Plus SpaceX will attempt a land landing of the 156 foot tall first stage back at the Cape at Landing Zone 1 some 9 minutes after liftoff.

To date SpaceX has successfully recovered 10 boosters, 4 by land and 6 by sea, over the past 18 months – in a feat straight out of science fiction but aimed at drastically slashing the cost of access to space.

If you can’t personally be here to witness the launch in Florida, you can watch NASA’s live coverage on NASA Television and the agency’s website.

The weather looks somewhat iffy at this time with a 70% chance of favorable conditions at launch time according to Air Force meteorologists with the 45th Space Wing at Patrick Air Force Base. The primary concerns on June 1 are for afternoon thunderstorms, anvil clouds and cumulus clouds.

The odds drop to 60% favorable for the scrub day on June 3.

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.

The 20-foot high, 12-foot-diameter Dragon is carrying almost 5,970 pounds of science research, crew supplies and hardware to the orbiting laboratory in support of Expedition 52 and 53 crew members.

The flight will deliver investigations and facilities that study neutron stars, osteoporosis, solar panels, tools for Earth-observation, and more.

The unpressurized trunk of the spacecraft also will transport 3 payloads for science and technology experiments and demonstrations.

The truck payloads include the Roll-Out Solar Array (ROSA) solar panels, the Multiple User System for Earth Sensing (MUSES) facility which hosts Earth-viewing instruments and tools for Earth-observation and equipment to study neutron stars with the Neutron Star Interior Composition Explorer (NICER) payload.

NICER is the first ever space mission to study the rapidly spinning neutron stars – the densest objects in the universe. The launch coincidentally comes nearly 50 years after they were discovered by British astrophysicist Jocelyn Bell.

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.

The recycled Dragon has undergone some refurbishments to requalify it for flight.

If all goes well, Dragon will arrive at the ISS 2 days after launch and be grappled by Expedition 51 astronauts Peggy Whitson and Jack Fischer using the 57 foot long (17 meter long) Canadian-built robotic arm.

They will berth Dragon at the Earth-facing port of the Harmony module. .

Overall CRS-11 marks the 100th launch from pad 39A and the sixth SpaceX launch from this pad.

SpaceX leased pad 39A from NASA in 2014 and after refurbishments placed the pad back in service this year for the first time since the retirement of the space shuttles in 2011. To date this is the sixth SpaceX launch from this pad.

Previous launches include 11 Apollo flights, the launch of the unmanned Skylab in 1973, 82 shuttle flights and five SpaceX launches.

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.

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.
