LAUNCH ALERT: Saturday, February 18 at 10:01 EST (15:01 UTC), SpaceX will make history as a Falcon 9 Full Thrust (FT) rocket will rise from NASA’s legendary Launch Complex 39A (LC-39A) as part of Commercial Resupply Service 10 (CRS-10 or SPX-10) to resupply the International Space Station (ISS). Dragon will be captured and berthed to Stations Harmony module (Node-2) on Monday, February 20 where it will remain for approximately one month before returning to Earth.
This will be Space-X’s 30th Falcon 9 flight (F9-31) and the parameters of this mission will allow for a Return To Landing Site (RTLS) where the first stage of the Falcon 9 will return to, and land back at Cape Canaveral at SpaceX’s Landing Zone 1 (LZ-1) (former LC-13) allowing them to forego landing on their East Coast Autonomous Spaceport Drone Ship (ASDS), Of Course I Still Love You (OCISLY). If successful this will be SpaceX’s 8th landing overall; 5 on drone ships and 3 on land.
NASA Launch Complex-39A (LC-39A): On May 25, 1966 test Saturn V (500F) was rolled out to LC-39A and just over a year later on November 9, 1967, LC-39A would see its first flight use as the first Saturn V; Apollo 4 (SA-501) launched into the Florida sky. From that day, all but one Saturn V (Apollo 10) would launch from that historic site to include all 12 humans in the history of our species to walk on the Moon and the launch of Skylab for a total of 12.
In the coming years, 39A would also see the first Space Shuttle stand full stack at the 39 complex, OV-101 Enterprise for fit check testing. STS-1 Columbia launched from 39A on April 12, 1981 and on July 8, 2011 STS-135 Atlantis would close out the Shuttle program from that same pad. In the years between, all 6 Shuttles would stand at 39A for a total of 80 launches.
On December 13, 2013, NASA leased LC-39A to SpaceX exclusively for 20 years. When SpaceX’s CRS 10 leaves Earth to resupply the Space Station that 39A helped build, it will also mark the 93rd launch from 39A and it will also be the first non-Saturn V or Shuttle to launch from 39A. In the years ahead, SpaceX plans to launch regularly from 39A to include the Falcon 9 Heavy and humans as well.
Autonomous Spaceport Drone Ships (ASDS): Were built at the Conrad Shipyard in Morgan City, Louisiana, the same place that NASA’s Pegasus barge is being refitted to support the SLS program. Pegasus carried lots of equipment throughout the years but most famously the space shuttle external fuel tanks from NASA’s Michaud Plant in Louisiana to KSC.
SpaceX’s barges are 300 by 100 ft. with “wings” that extend that width to 170 ft. It has also been fitted with thrusters repurposed from deep sea oil rigs that are able to hold balance and position to within 3 meters even in storm conditions. ASDS’s are painted black with the SpaceX “X” logo, a yellow inner ring and outer white ring acting as a bull eye. The East Coast ASDS is “Of Course I Still Love You (OCISLY)” and the West Coast’s ship is “Just Read The Instructions (JRTI).”
In total there have been three ASDS’s. The first of which was Marmac 300, a deck barge named “Just Read The Instructions (JRTI).” That ASDS was used for two east coast landing attempts (CRS 5 & 6), deconstructed and retired. East Coast duties were then transferred to Marmac 304 named “Of Course I Still Love You (OCISLY).” A third ASDS, Marmac 303 was constructed and stationed on the West Coast where it fields launches from Vandenberg AFB, CA. Its name, “Just Read The Instructions (JRTI).”
These fun yet odd names come from Scottish Sci-fi legend Iain Banks’s “Culture” series of 10 novels. They are spacecraft known as General Contact Units (GCU’s) from the novel “Player of Games.” Other spacecraft in the series (which get to name themselves) are even more entertaining such as “Size Isn’t Everything,” “No More Mr. Nice Guy” and “Death and Gravity.” Here’s a fun Wiki page with more info: http://en.wikipedia.org/wiki/List_of_spacecraft_in_the_Culture_series
The Rocket: The greatly improved Falcon 9R FT rocket is a 2-stage partially reusable rocket with future ambitions of becoming fully reusable. The new version is 3.7 m (12 ft.) in diameter and 70 m (229.6 ft.) tall which is about 1.6 m (5.6 ft.) taller than the Falcon 9 v1.1 or “Block 2” in order to house a higher volume fuel tank. It is also fitted with upgraded Merlin family main engines. They have replaced the 9 Merlin-1D (and before them were the 1C engines), with the more powerful Merlin-1D+ engines that will provide a thrust of nearly 694,000kg (1.53 million lb.) at sea level. Each Merlin-1D+ provides 180,000 lb. (81,600 kg) of thrust at sea level, which equates to roughly a 20% increase in overall performance. If you add that with the new process of densifying the fuel and improving the overall airframe, the total gain in performance is about 33%.
Dragon Spacecraft (when in use) = The Dragon spacecraft is about 23.6 ft. (7.2 m) tall with trunk attached and 12 ft. (3.7 m) wide. It’s comprised of two main sections; the pressurized cargo area which can carry 388 cubic ft. of cargo as well as the unpressurized cargo area. The trunk (unpressurized area) carries 494 cubic ft. of cargo as well as the solar arrays. OR: Main Composite Payload Fairing (when in use) = the composite payload fairing is 13.1 meters (43ft) in length and 5.2 meter (17ft) in diameter. Dragon, along with Russia’s Progress & Soyuz, Europe’s (ESA) Automated Transfer Vehicle (ATV), Orbital ATK’s Cygnus and Japan’s (JAXA) H-II Transfer Vehicle (HTV), is one of only six vehicles that can fly to the Space Station. While Russia’s Soyuz is currently the only crewed means of reaching and returning from Station, SpaceX’s Dragon is currently the only means of returning experiments and supplies back to Earth from Station.
Second Stage: Powered by a single Merlin-1D+ Vacuum engine with aluminum-lithium alloy tanks fueled by liquid oxygen and rocket grade kerosene (LOX/RP-1). The Merlin 1D+ are basically the same Merlin-1D engines used previously but instead of utilizing them at only 80%, they will now be operating at 100%. This stage can be restarted multiple times to place multiple payloads into desired orbits. For maximum reliability, the second stage has redundant igniter systems and has a burn time of 375 seconds.
Interstage: a composite structure that connects the first stage to the second stage and holds the release and separation system. Its al all pneumatic stage separation system for low shock, highly reliable separation that can be tested on the ground, unlike pyrotechnic systems used on most launch vehicles.
Core/Boost Stage is powered by nine (9) Merlin-1D+ engines in their circular “octaweb” configuration with aluminum-lithium alloy tanks fueled by liquid oxygen and rocket grade kerosene (LOX/RP-1). The Merlin 1D+ engines are basically the same Merlin-1D engines used previously but instead of utilizing them at only 80%, they will now be operating at 100%. The core stage has a burn time of 180 seconds and is gradually throttled. Its 9 Merlin-1D+ engine system can sustain up to two engine shutdowns during flight and still successfully complete its mission.
The first stage is fitted with four independently steerable grid fins that help control pitch, yaw and roll during vertical decent. It’s also fitted with four landing legs that will extend before touchdown.
