OrbitX

OrbitX is a astronomy 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 OrbitX rather than just read about it. In short: Orbital Exploration Technologies, Inc., also known as Orbital Exploration or OrbitX, was a Philippine aerospace and space transportation company. History OrbitX was established on June 2, 2019 as OrbX, a private venture by a group of youth including Dexter Baño Jr., Enzo Victor, and Paulo Sairel.

Key takeaways

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

Reference excerpt

Orbital Exploration Technologies, Inc., also known as Orbital Exploration or OrbitX, was a Philippine aerospace and space transportation company.

History OrbitX was established on June 2, 2019 as OrbX, a private venture by a group of youth including Dexter Baño Jr., Enzo Victor, and Paulo Sairel. OrbitX's short term goal was to develop the first indigenous reusable rocket, and the long-term goal was to send the first Filipino to Mars and back. OrbitX is known as the Philippines' first commercial spaceflight company. Its first intended flagship project was the Haribon SLS-1 launch vehicle. OrbitX started a crowdfunding campaign which received support from Southeast Asian firm and Genix Ventures and other private individuals. It also received a two-year funding of $6,500 for research purposes from the Amazon Web Services. In late 2023, the website for OrbitX was shut down. As of 2026, the website exists as a blog.

Projects

Haribon SLS-1

OrbitX was developing its own space launch vehicle which it dubs as the Haribon SLS-1. It was planned to be propelled using components also to be developed by OrbitX: Tamaraw Rocket Engine and RP-2 fuel, a plastic-derived fuel. RP-2 got its named from RP-1, the refined kerosene that is typically used in rockets. In January 2021, the project moved to Technology Readiness Level 4 phase of development with its components still being validated in a laboratory environment. The rocket was projected to carry a payload of 200 kilograms (440 lb) into low Earth orbit. The company planned to have the maiden launch of the Haribon SLS-1 sometime between 2023 and 2024.

Fuels Among OrbitX's research was the potential use of algae as biofuel for both small and large-scale space launch vehicles. The company has noted that algae-derived biofuel has already had prior use on aircraft; particularly in a Houston–Chicago Boeing 737 flight. It was also developing, OrbitX RP-2, its own proprietary fuel derived from pyrolysis-processed waste plastic.

Orbital Coin (ORBX) On February 10, 2021, OrbitX teased about their in-house cryptocurrency. On February 12, 2021, OrbitX announced the cryptocurrency named Orbital Coin or ORBX, as they'll also fund the rocket using their in-house cryptocurrency. On July 5, 2021, OrbitX announced their initial coin offering, as scheduled on July 20. ORBX was developed by ProofSys.io and OrbitX.

Cooperation OrbitX relayed its findings and developments to the Philippine Space Agency (PhilSA), the national space agency of the Philippine government, although OrbitX itself was a private venture and was independent from PhilSA. It also had partnerships and affiliations with the Space4Impact and Space Impulse, the Green Party of the Philippines, the Polytechnic University of the Philippines, and the government's Department of Environment and Natural Resources.

Worked examples

Example 1 — a first encounter with OrbitX

Start with the simplest possible case. Write down what OrbitX claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 OrbitX 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 OrbitX 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 OrbitX

In research: OrbitX appears in astronomy 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 OrbitX 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: OrbitX is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2019 establishments in the Philippines, Aerospace companies of the Philippines, Algal fuel producers, so understanding it makes those chapters shorter.
In everyday life: Look for OrbitX 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.

Frequently asked questions

What is OrbitX in simple terms?

Orbital Exploration Technologies, Inc., also known as Orbital Exploration or OrbitX, was a Philippine aerospace and space transportation company. History OrbitX was established on June 2, 2019 as OrbX, a private venture by a group of youth including Dexter Baño Jr., Enzo Victor, and Paulo Sairel.

Why does OrbitX matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study OrbitX?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
