Following the two successful launches over the weekend the International Space Station now has two additional vehicles attached.
Monday evening the Progress MS-03/64P vehicle completed it’s mission with a picture perfect docking to the Pirs module.
And early this morning ISS Commander Jeff Williams and Flight Engineer Dr. Kate Rubins successfully captured the Dragon CRS-9 spacecraft.
Three hours later Dragon was berthed to the station completing the two day journey and allowing the crew to begin operations to access the cargo.
Now that Dragon is attached to the station the crew can begin preparations for a Spacewalk to attached the International Docking Adapter 2 (IDA-2) that was carried to the station in the trunk of the vehicle. This is critical to the future of the Commercial Crew program for SpaceX and Boeing as it will allow there new vehicles to automatically dock with the station.
The second launch of International Space Station Cargo this weekend was completed successful this morning following the successful delivery to orbit of the Dragon capsule.
Following a smooth countdown the Falcon 9 rocket lifted off at 12:45:29 am EDT today propelling the Dragon capsule to orbit, the first stage then returned to the Cape for a successful landing at LZ1.
Once in orbit the Dragon capsule deployed it’s Solar Array’s before starting its journey to the station.
In the first of two International Space Station Cargo launches this weekend the Russian Progress 64P was successfully delivered to orbit today by it’s Soyuz booster.
Following a smooth countdown the Soyuz rocket lifted off at 5:41pm EDT.
This is the third flight of the MS version of the Progress Cargo vehicle and will be using a two day rendezvous profile with arrival at the station expected on Monday 18th at 8:22 PM EDT.
SpaceX continued it’s launch campaign today with the successful launch and deployment of the Eutelsat 117 West B and ABS-2A satellites.
The two Boeing built spacecraft utilize an all electric propulsion system allowing them to be launched on a single Falcon 9 vehicle.
Unfortunately the first stage didn’t survive the landing attempt, as explained by Elon Musk below.
Elon tweeted a follow up that should address that type of issue in the future

SpaceX continued it’s 2016 campaign with the successful launch of the Thaicom 8 satellite this evening.
Originally scheduled for yesterday 5/26 the launch was postponed to allow more time to investigate an issue found during the countdown.
Today’s countdown proceeded smoothly before the Falcon 9’s engines roared to life at 5:39 pm EDT, following a 2:35 minute burn the first stage completed it’s job and returned to the droneship “Of Course I Still Love You”, while the second stage propelled the satellite to orbit.
As with the previous two launches SpaceX returned the first stage to the droneship and again completed a successful landing. As with the JCSAT landing this was made more difficult due to the speed of the first stage during re-entry.

SpaceX successfully launched the JCSAT 14 satellite this week for SKY Perfect JSAT, and once again landed the Falcon 9 first stage on the ASDS “Of Course I Still Love You”.
Unlike the landing during the CRS-8 mission this was more complicated due to the speed of the first stage booster at separation. According to a SpaceX spokesperson during the live broadcast the stage was travelling twice as fast. This required that three of the engines be used for the landing burn instead of the one previously.
During the broadcast it almost looked like the first stage had crashed into OCISLY but once the smoke cleared and the lights on the drone ship came on it was clear that the stage was sitting almost in the center of the landing zone. This is the third landing of the Falcon 9 first stage and as Elon Musk tweeted they are going to need to find more space if they keep this going.

Ten months after the failed CRS-7 launch SpaceX resumed their servicing missions to the International Space Station today with the successful launch of their Dragon spacecraft.
Following a smooth countdown the Falcon 9 lifted off at 4:43 pm EDT to begin a 10 minute climb to orbit.
As with previous launches SpaceX also attempted to land the first stage on the Drone Ship after it had completed it’s job getting the 2nd stage and Dragon on their way. Unlike previous attempts to land on the Drone Ship this time they were successful.
Dragon is now in orbit and making it’s way towards a capture on Sunday.
The Russian Progress MS-02 spacecraft launched successfully today beginning a two day journey to dock with the International Space Station.
Roscosmos elected to do the two day journey to allow time to fully test all the upgraded systems on the newer MS version of the vehicle. The first Soyuz MS crewed mission is due to launch in June and validation of the systems is required before that can occur.
This is the second of three cargo vehicles scheduled to travel to the station in less than a month.
Last night United Launch Alliance (ULA) launched an Orbital ATK Cygnus spacecraft towards the International Space Station (ISS). This is the second Cygnus that has launched on an Atlas V rocket and will be the heaviest payload the Atlas V has ever launched. Even with the heavier payload ULA didn’t require any Solid Rocket Boosters as Cygnus is only launching to Low Earth Orbit.
Continuing in the tradition of previous Cygnus launches Orbital ATK named this vehicle the S.S. Rick Husband in honor of Col. Rock Husband USAF.
Update: After the launch a number of people noticed that the burn time on the Centaur upper stage was almost a minute longer than originally planned. ULA has since announced that this was caused by the first stage RD-180 engine shutting down 5 seconds earlier than originally planned requiring the Centaur to compensate for the difference. They are investigating why the engine shutdown early and don’t currently know if this could impact the next Atlas V launch.
SpaceX continued it’s 2016 launch campaign today with the successful delivery of the SES-9 satellite to orbit. This was the third successful launch since the June 2015 failure and the second launch of the Falcon 9 Full Thrust version of the rocket.
SpaceX attempted the launch several times but had to scrub due to several reasons including LOX cooling/loading issues, wayward boats and severe wind sheer.
The vehicle lifted off from Cape Canaveral at 18:35 EST today following a smooth countdown. Once in orbit the second stage re-started to allow the payload to be delivered to the desired orbit.
To allow SES to make the SES-9 satellite operational as quickly as possible SpaceX forgo the chance to return the first stage to the Cape and instead elected to attempt another landing at sea on there Autonomous Spaceport Drone Ship “Of Course I still Love You”.
