SpaceX CRS-14

SpaceX CRS-14 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SpaceX CRS-14 rather than just read about it. In short: SpaceX CRS-14, also known as SpX-14, was a Commercial Resupply Service mission to the International Space Station launched on 2 April 2018. The mission was contracted by NASA and was flown by SpaceX.

Key takeaways

SpaceX CRS-14 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SpaceX CRS-14 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SpaceX CRS-14 from memory before moving on to harder problems.

Reference excerpt

SpaceX CRS-14, also known as SpX-14, was a Commercial Resupply Service mission to the International Space Station launched on 2 April 2018. The mission was contracted by NASA and was flown by SpaceX. This mission reused the Falcon 9 first stage booster previously flown on CRS-12 and the Dragon capsule flown on CRS-8.

Mission overview In early 2015, NASA awarded a contract extension to SpaceX for three additional CRS missions (CRS-13 to CRS-15). In June 2016, a NASA Inspector General report had this mission manifested for February 2018. The flight was then delayed to 9 February and 13 March 2018. Launch occurred on 2 April 2018 at 20:30 UTC on a Falcon 9 Full Thrust rocket from Cape Canaveral Air Force Station Space Launch Complex 40. The Dragon spacecraft rendezvoused with the ISS on 4 April; it was captured by Canadarm2 at 10:40 UTC and was berthed to the Harmony module at 13:00 UTC. It remained there for just under 31 days before being unberthed by Canadarm2 on 5 May 2018, scheduled for 05:30 UTC. The spacecraft was released at 13:23 UTC and autonomously backed away from the station to a safe distance before firing its thrusters for a deorbit burn at 18:06 UTC. Dragon splashed down in the Pacific Ocean at 19:03 UTC to be retrieved by a SpaceX recovery crew and transported to the Port of Los Angeles, returning 1,743 kg (3,843 lb) of cargo to Earth. No attempt was made to recover the first stage booster; instead, the booster was used to conduct experimental maneuvers designed to test the limits of its flight trajectory.

Payload NASA contracted for the CRS-14 mission from SpaceX and therefore determined the primary payload, date/time of launch, and orbital parameters for the Dragon space capsule. CRS-14 carried a total of 2,647 kg (5,836 lb) of material into orbit. This includes 1,721 kg (3,794 lb) of pressurised cargo with packaging bound for the International Space Station, and 926 kg (2,041 lb) of unpressurised cargo. The unpressurised component is composed of two external station experiments, Atmosphere-Space Interactions Monitor (ASIM) and Materials ISS Experiment Flight Facility (MISSE-FF), and a Pump and Flow Control Subassembly (PFCS) orbital replacement unit for the station. Multiple payloads from national labs are also included, one of which is the RemoveDEBRIS mission which will be deployed from the ISS. The mission aims to test a harpoon and a net on test debris that the mission carries to evaluate the viability of these methods to be used in future missions to remove real space debris. At the end of the mission the RemoveDEBRIS spacecraft will deploy a large dragsail to accelerate its own deorbit to avoid becoming space debris itself. HP was also contracted by NASA to install a new inkjet printer for the US lab. The following is a breakdown of cargo bound for the ISS:

Science investigations: 1,070 kg (2,359 lb) Crew supplies: 344 kg (758 lb) Vehicle hardware: 148 kg (326 lb) Spacewalk equipment: 99 kg (218 lb) Computer resources: 49 kg (108 lb) New HP Workstation laptops HP Envy inkjet printer Russian hardware: 11 kg (24 lb) External payloads: 926 kg (2,041 lb) Atmosphere-Space Interactions Monitor (ASIM) Materials ISS Experiment Flight Facility (MISSE-FF) Pump and Flow Control Subassembly (PFCS)

Worked examples

Example 1 — a first encounter with SpaceX CRS-14

Start with the simplest possible case. Write down what SpaceX CRS-14 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SpaceX CRS-14 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SpaceX CRS-14 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SpaceX CRS-14

In research: SpaceX CRS-14 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses SpaceX CRS-14 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: SpaceX CRS-14 is common in secondary-school and first-year university syllabi. It links to neighbouring topics SpaceX Dragon 1, SpaceX payloads contracted by NASA, Spacecraft launched by Falcon 9 Block 4 rockets, so understanding it makes those chapters shorter.
In everyday life: Look for SpaceX CRS-14 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
