Launch Alert!!! Saturday, August 11, 2018 at 03:53 EDT (00:53 PDT & 07:53 UTC) the United Launch Alliance (ULA) will be launching the beautifully powerful, heavy lift, Delta IV Heavy from Cape Canaveral’s Space Launch Complex 37B (SLC-37B or “Slick” 37B) to deliver the long awaited Parker Solar Probe (PSP) science mission to the Sun for NASA.

Note: This will be the 10th launch of the Delta IV Heavy and the Parker Solar Probe (full mission post to come) is the first NASA science mission to be dedicated to a living scientist (Eugene Parker).

The Parker Solar Probe (PSP): This mission will ask the small Parker Solar Probe to study the Sun’s corona by coming within 4 million miles of the surface of the Sun to collect data and in the process it will become the fastest human made object ever created as it will reach a top speed of 430,000 mph. (692,018 km/h).

The United Launch Alliance Delta IV Heavy:

Height: 70.7 m (232 ft.)

Core Diameter: 5.1 m (16.7 ft.)

Width at Base: 15.3 m (50.1 ft.)

Stages: 2 or 3

Boosters: 2

Total Engines: 4 (3 in the first stage and 1 in the second stage)

Total Liftoff Thrust (sea level): 9,420 kN (2,120,000 lbf)

Gross Mass: 733,000 kg (1,616,000 lb.)

Payload to Low Earth Orbit (LEO): 28,370 kg (62,540 lb.)

Payload to Geosynchronous Transfer Orbit (GTO): 14,210 kg (31,330 lb.)

Payload to Geosynchronous Orbit (GEO): 6,580 kg (14,500 lb.)

Cost: $350 million

 

Main Composite Payload Fairing (PLF): The Delta IV Heavy main payload fairing is a 5.1 m (16.7 ft.) diameter composite bisector (two-shell) protective enclosure that protects the spacecraft from the atmospheric turbulence of ascent. Once the vehicle achieves a safe altitude, the fairings are jettisoned and the spacecraft is then exposed to space.

Delta Cryogenic Second Stage (DCSS):

Height: 13.7 m. (45 ft.)

Diameter: 5.1 m (17 ft.)

Engine(s): Single Aerojet Rocketdyne RL10-B-2

Engine Chambers: 1

Engine Type (cycle): Expander Cycle

Propellant Feed Method: Turbopump

Chamber Pressure:

Fuel Type: Liquid

Fuel: Fuel: Liquid hydrogen (LH2). LH2 provides a higher specific impulse than rocket propellant 1 (RP-1) or as it’s sometimes called highly refined kerosene, but it’s more expensive, not stable at room temperature (must be kept cold), more explosive, less dense and less powerful by volume.

Oxidizer: 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): 110.1 kN (24,800 lbf.)

Single RL-10 Thrust to Weight Ratio: N/A

Specific Impulse (vacuum): 462 s

Burn Time: 1125 s

Restart Ability: Yes

Reusable?: No

Common Booster Core (CBC) Boosters:

How Many: 2

Height: 40.8 m. (134 ft.)

Diameter: 5.1 m (17 ft.)

Engine(s): 1 Aerojet Rocketdyne RS-68A

Engine Chambers: 1

Engine Type (cycle): Gas generator

Propellant Feed Method: Turbopump

Chamber Pressure: 10.26 MPa or 102.6 bar or 1,488 psi

Fuel Type: Liquid

Fuel: Liquid hydrogen (LH2). LH2 provides a higher specific impulse than rocket propellant 1 (RP-1) or as it’s sometimes called highly refined kerosene, but it’s more expensive, not stable at room temperature (must be kept cold), more explosive, less dense and less powerful by volume.

Oxidizer: 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.

Single RS-68A Thrust (sea level): 3,137 kN (705,000 lbf.)

Single RS-68A Thrust to Weight Ratio: 47.4

Specific Impulse (sea level/vacuum): 360 s/412 s

Burn Time: 242 s

Restart Ability: No

Reusable?: No
