LAUNCH ALERT! Saturday, March 2, 2019 at 02:48 EST (07:48 UTC) SpaceX Falcon 9 (core 1051.1) will be launching from NASA’s legendary Launch Complex 39A (LC-39A) at Kennedy Space Center carrying, for the first time, SpaceX’s Crew Dragon spacecraft (Dragon D2-1 or C201) as part of Demonstration Mission 1 (DM-1) for NASA’s Commercial Crew contract. This first of two demonstration missions to the International Space Station (ISS) will be uncrewed and if successful an in-flight abort test with the same spacecraft will take place this summer and if that succeeds then DM-2 will likely follow later this year and be the first to carry astronauts (Doug Hurley & Bob Behnken) into space from the United States since the launch of STS-135 Atlantis, which launched from the same launch pad on July 8, 2011. This will end the longest drought in U.S. human spaceflight history. The longest drought prior to this was the gap between the landing of the Apollo-Soyuz Test Project on July 24, 1975 and the first launch of the Space Shuttle, STS-1 Columbia on April 12, 1981.

The timeline for this mission calls for launch from KSC and booster landing on March 2 (Sat), with rendezvous and autonomous docking to Station taking place on the 3rd (Sun) where Dragon will deliver roughly 400 pounds of supplies and a “Starman” in full SpaceX flight suit for monitoring. Dragon is scheduled to remain at station until March 8 (Sat) when it will undock, deorbit and splashdown to complete a successful mission.

Stats: This will be SpaceX’s 3rd launch of 2019 and the 75th SpaceX flight overall (5 Falcon 1, 69 Falcon 9, 1 Falcon Heavy). Mission parameters will allow for a landing on SpaceX’s East Coast Autonomous Spaceport Drone Ship (ASDS) “Of Course I Still Love You (OCISLY)” which will bring to total successful landings to 35; 22 on drone ships and 13 on land.

Autonomous Spaceport Drone Ships (ASDS) were built at the Conrad Shipyard in Morgan City, Louisiana, the same place that NASA’s Pegasus barge was 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 will soon have two drone ships. The current ASDS is “Of Course I Still Love You (OCISLY)” and soon to join it will be “A Shortfall Of Gravitas (ASOG)” 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 SpaceX Falcon 9 Rocket:

Height: 70m (229.6 ft.)

Core Diameter: 3.66 m (12 ft.)

Width at Base: 3.66 m (12 ft.)

Stages: 2

Boosters: 0

Total Engines: 10 (9 in the first stage and 1 in the second stage)

Total Liftoff Thrust (sea level/vacuum): 7,607 kN (1,710,000 lbf) / 8,227 kN (1,849,500 lbf)

Gross Mass: 549,054 kg (1,207,920 lb.)

Payload to Low Earth Orbit (LEO): 22,800 kg (50,265 lb.)

Payload to Geostationary Transfer Orbit (GTO): 8,300 kg (18,300 lb.)

Payload to Mars: 4,020 kg (8.860 lb.)

Cost: $62 million

Dragon 2 (Crew Dragon)(when in use): SpaceX’s reusable Crew Dragon or Dragon 2 is about 27 ft. (8.1 m) tall with trunk attached and 12 ft. (3.7 m) wide when mated to trunk. This system is rated to carry 7 astronauts (4 comfortably) and boasts 350 cu ft. or pressurized volume and 490 cu ft. of unpressurized volume. Unlike its cargo counterpart, Dragon 2 will be fully autonomous whereas the cargo Dragon must be grappled and berthed to and from station. In the future, Dragon 2 will come in 2 configurations; crew and cargo; effectively retiring the original Dragon spacecraft. Dragon 2 utilizes 8 SuperDraco thrusters housed in 4 pods that will act as a “pusher” launch escape system. If an emergency occurs, the SuperDraco’s will fire, creating 120,000 lb. of axial thrust to push the crew to safety. The SuperDraco’s can also be restarted and used as necessary. For maneuvering in the vacuum of space, Dragon 2, like the original Dragon, will utilize 18 Draco thrusters that produce 90 lb. of thrust each. Originally, SpaceX has planned to land propulsively with the SuperDraco engines but they have, at least for now forgone that for the traditional parachute system. Dragon 2 will have four parachutes.

Dragon Cargo Spacecraft (when in use): SpaceX’s reusable 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. 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.

Main Composite Payload Fairing (when in use): the two shell, composite payload fairing is 13 m (43 ft.) in length and 5.2 m (17 ft.) in diameter. The fairings are used to protect the spacecraft during ascent through atmospheric turbulence and into space. Once the rocket has reached a safe altitude the fairings jettisoned, exposing the spacecraft(s). SpaceX has been experimenting with PLF recovery using parachutes, small thrusters and a recovery ship named Mr. Steven which is affixed with a large net that they intend to land the PLF shell on.

SpaceX Falcon 9/Falcon Heavy Second Stage:

Height: 10 m. (33 ft.)

Diameter: 3.66 m (12 ft.)

Engine(s): Single Merlin Vacuum Engine

Engine Chambers: 1

Engine Type: Gas generator

Propellant Feed Method: Turbopump

Chamber Pressure: 9.7 MPa or 97 bar or 1,410 psi

Fuel Type: Liquid

Fuel: Chilled Rocket propellant-1 (RP-1) or highly refined kerosene. Lower specific impulse than liquid hydrogen (LH2) but is cheaper, room temperature stable, less explosive and denser. RP-1 is much more powerful than LH2 by volume and much less toxic than other room temperature fuels such as hydrazine (N2H4).

Oxidizer: Subcooled Liquid Oxygen (LOX). LOX is often coupled with rocket propellant-1 (RP-1), liquid hydrogen (LH2) and methane (CH4) as it creates a high specific impulse.

Thrust (vacuum): 934 kN (210,000 lbf.)

Single Merlin 1D Thrust to Weight Ratio: 180.1

Specific Impulse (vacuum): 348 s

Burn Time: 397 s

Restart Ability: Yes

Reusable?: No

SpaceX Falcon 9/Falcon Heavy Interstage: The interstage is a 4.4m (14.4 ft.) composite structure that connects the first stage to the second stage and holds the release and separation system. It’s an 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.
