Zero 2 Infinity Type Private S.L. Industry Aerospace Founder Jose Mariano López-Urdiales Area served Worldwide Key people Jose Mariano López-Urdiales (CEO) Products Bloostar Bloon Elevate

José Mariano López Urdiales in October 2019

**Zero 2 Infinity** (**0II∞**, sometimes rendered as **Zero2Infinity**) is a private Spanish [company](/source/Company) developing [high-altitude balloons](/source/High-altitude_balloon) intended to provide access to [near space](/source/Near_space) and [low Earth orbit](/source/Low_Earth_orbit) using a balloon-borne pod and a balloon-borne [launcher](/source/Launch_vehicle).

The company was founded in 2009 by [aerospace engineer](/source/Aerospace_engineer) Jose Mariano López-Urdiales, the current CEO. It is headquartered in [Barberà del Vallès](/source/Barber%C3%A0_del_Vall%C3%A8s), [Barcelona](/source/Barcelona), Spain.

Zero 2 Infinity has been testing high-altitude balloons and launching small payloads to high altitudes for scientific institutions and commercial firms for testing elements above most of the Earth's atmosphere. Their launch system has a significantly lower impact on the environment, an advantage over conventional systems. The company's pod named Bloon may also be used for tourism.[2] In late 2016, its CEO had suggested that commercial flights could take place as early as 2019.[3] As of 2020, the company aims to carry paying passengers to above 30 km altitude by 2021.[4]

## Products

The company has three main offerings:

- Bloostar: a balloon-borne [launcher](/source/Launch_vehicle) for carrying payloads such as [small](/source/Small_satellite), [micro](/source/Small_satellite#Microsatellites), and [nanosatellites](/source/Nanosatellite) to orbit, based on [rockoon](/source/Rockoon) technology.

- Bloon: a balloon-borne zero emission craft for launching crewed vehicles to near space for scientific research, educational and also [space tourism](/source/Space_tourism) purposes.[5]

- Elevate: a service provided to fly payloads to near space for science, communications, satellite testing, meteorology and marketing purposes.

Bloostar launch cycle

**Bloostar** is a [launch vehicle](/source/Launch_vehicle) currently in development, intended to compete in the [small satellite](/source/Small_satellite) launch market.[6] It is based on the [rockoon](/source/Rockoon) concept: the first stage of the ascent is conducted by the use of a [high-altitude balloon](/source/High-altitude_balloon) up to 30 km (19 mi), where the [rocket](/source/Rocket) platform is ignited and detached from the balloon to insert the payload into [orbit](/source/Orbit).[7] The design is intended to be capable of delivering a 140 kg payload to a 200-km [low Earth orbit](/source/Low_Earth_orbit), or a 75 kg payload to a 600-km [Sun-synchronous orbit](/source/Sun-synchronous_orbit).[8][9]

#### Design

The launch vehicle is composed of a set of liquid fuel engines clustered as concentric [toroids](/source/Toroid) attached to the central payload. Each toroid works as a stage during the rocket climb once it has been ignited from around 30 km (19 mi) above ground level. The stages are progressively separated from the vehicle, similarly to conventional satellite launch using a rocket with [parallel staging](/source/Parallel_staging).

The design includes a total of 13 engines split across three stages using methalox ([liquid methane](/source/Methane#Liquid-methane_rocket_fuel) and [liquid oxygen](/source/Liquid_oxygen)) fuel, with the first and second using [filament-wound](/source/Filament_winding) [carbon fiber](/source/Carbon_fiber) tanks, and the third using "flexible multilayer tanks". The first, outermost stage is a toroid weighing nearly 4t with six *Teide 2* engines each producing 15 kN of thrust; the second stage is a smaller (700kg) toroid with six smaller *Teide 1* engines each producing 2 kN of thrust; the 400kg third stage is positioned at the centre of the toroids with a single Teide 1 engine. By using propellant crossfeed, all available engines will fire simultaneously but only the fuel tank in the outermost stage will be depleted at a time, increasing performance. As the engines will only ever fire at very high altitude, all 13 will be optimized to produce maximum thrust in vacuum or near-vacuum conditions, similar to the upper-stage engines of conventional rockets.[10][8][9] Due to their high-altitude-only use, much lower combustion chamber pressures are required and thus a simple [pressure-fed engine](/source/Pressure-fed_engine) design is used, substantially reducing cost and complexity by omitting [turbopumps](/source/Turbopump).[11] The combustion chambers for the Teide 1 engines are [3D printed](/source/3D_printing) by the [Andalusian Foundation for Aerospace Development](https://en.wikipedia.org/w/index.php?title=Andalusian_Foundation_for_Aerospace_Development&action=edit&redlink=1).[10]

The use of several toroid-shaped stages results in an increased stand-off distance to the sonic line during [atmospheric entry](/source/Atmospheric_entry), reducing the possibility of damaging the stages because of the high temperatures reached. Another promoted advantage is the capability to launch satellites with no need of folding them, as a flat-shaped vehicle is capable of fitting panel-deployed satellites right from the launch site.[12]

The balloon components will be landed and potentially reused. According to López Urdiales, the Bloostar rocket launch vehicle *"has been designed to be [reusable](/source/Reusable_launch_system), technically, but not as part of the business plan. The engines burn methane and oxygen for many reasons, but one is that it creates less soot and leaves the engines reusable. Also, the shape of a torus has been selected to reduce the aero-heating on reentry. The optimal shape in vacuum is similar to the optimal shape for reentry (blunt). The optimal shape for ascent is very different (slender). Bloostar has been designed from its ignition taking into account ‘the way back down.’ It's easier to do if the ‘way up’ is taken care of by the balloon."*[13] Recovery will be attempted, however, and consideration has been given for an eventual system by which the first stage will descent top-down, using a portion of its dorsal fairing as an ablative [heat shield](/source/Heat_shield), and slow to be caught in a sea-based net.[11]

#### Development history

Development of Bloostar began in 2013. The first flight test was successfully conducted in March 2017, in which a less-than-half-scale prototype of the upper two stages was carried to 25 km altitude by balloon, separated, made a short burn using a small solid motor, and then was recovered intact by parachute.[8][11] According to the Payload User's Guide, Phase 2 of development will follow, which will involve suborbital flights of **nanobloorstar** (a third stage from a production Bloostar) with a 75 kg payload to 180 km altitude.[9]

At that time of the 2017 test flight the first commercial launch was projected for 2019.[8] However, López Urdiales subsequently noted this date could potentially slip as Zero 2 Infinity focused on its revenue-generating Elevate product line.[10]

### Bloon

Bloon is a zero emission craft in development, which consists of a high-altitude balloon-borne capsule to perform crewed flights to near space and a steerable parachute system for returning autonomously to Earth. It also refers to the balloon-borne craft prototype range of the same company: Bloon, Minibloon, Microbloon and Nanobloon, which are differentiated among them by their size.[14]

Considering that only a [helium](/source/Helium) balloon is responsible for lifting the load above most of the atmosphere, it is considered a [zero emission](/source/Zero_emission) craft.[15] With this technology, Bloon would carry up to 4 passengers and 2 pilots (6 total crew) to an altitude as high as 36 km (22 mi, 118,110 feet).[16] The vehicle would take from 1.5 to 2 hours to reach maximum altitude, and then stay there for up to 2 hours, with a final descent by steerable parachute after releasing the balloon, using airbags to smooth the landing.[17]

### Elevate

**Elevate** is a service provided to lift payloads to near space on a stratospheric balloon platform for purposes such as testing of (components of) spacecraft, drop tests, celestial observation or publicity. The useful load on a stratospheric zero pressure balloon can range from several kilograms to over 5000 kg and the target altitude varies between 20 and 42 kilometers. The duration at altitude or ‘float’ can be extended from hours to several days or even weeks depending on the launch location. Additional solutions such as solar arrays, battery power or advanced return options such as a guided parafoil (as opposed to a traditional parachute) and tailor-made solutions to customer requirements are also offered as part of the Elevate service.

## Flights

Zero 2 Infinity reports that it has conducted over 30 flights as of 2016.[3] The most important flights for Bloon are listed below[18]

Flight Designation Date Reached altitude (km) Reached altitude (miles) Reached altitude (feet) Crewed or Uncrewed nanobloon 1.0 November 2009 32 km 20 mi 104,987 feet Uncrewed nanobloon 2.0 June 2010 33 km 21 mi 108,268 feet Uncrewed microbloon 1.0 October 2010 24 km 15 mi 78,740 feet Uncrewed microbloon 2.0 May 2012 (non-successful flight) (non-successful flight) (non-successful flight) Uncrewed microbloon 2.0 November 2012 31 km 19 mi 101,706 feet Uncrewed microbloon 3.0 September 2013 27 km 17 mi 88,583 feet Uncrewed Bloon model January 2017 Tethered Tethered Tethered Uncrewed

On March 1, 2017, Zero 2 Infinity ignited its first rocket from Near Space, a Bloostar prototype. The flight took place at the [INTA](/source/Instituto_Nacional_de_T%C3%A9cnica_Aeroespacial) (Instituto Nacional de Técnica Aeroespacial) facilities in [El Arenosillo](/source/El_Arenosillo), Huelva. The balloon that took Bloostar to 25 km was launched from a boat in the Gulf of Cadiz. At 25 km the ignition of the rocket took place. Thegoals of the mission were: (i) validation of the telemetry systems in Space conditions, (ii) controlled ignition, (iii) stabilization of the rocket, (iv) monitoring of the launch sequence, (v) parachute deployment, and finally, (vi) sea recovery. All these goals were achieved in full.[19]
