Bloostar | Space Affairs


  • balloon ascent & rocket ignition

    The BLOOSTAR is launched from a ship sailing in international waters.

    Duration: 1.5 to 2 hours.
    Weight: 5.135 kg (without payload satellite with 75 kg)
    BLOOSTAR total engine power at ignition (all 13 engines): 104 kN

    The first phase of the flight is the balloon ascent into the close range between 20 and 25 kilometres.

    The balloon segment consists of:
    - Height altitude balloon (filled with helium, surface up to 90,000 square meters)
    - Flight-Train (located between the balloon and the gondola)
    - Balloon Gondola

    The second phase of the flight starts as soon as BLOOSTAR has been dropped from the balloon. Shortly afterwards, all 13 rocket engines of the BLOOSTAR will be ignited.

    The engines of the first stage run for 110 seconds, with the BLOOSTAR reaching a height of 80 kilometres at an inertial speed of 2.3 km/s. The first stage of the balloon's life cycle is completed by the end of the second stage.

  • Separation 1st Stage

    Total weight 1st stage: 3,958 kg
    (inertia mass 561 kg, fuel mass 3,397 kg)
    6 rocket engines with a total thrust in a vacuum of 15 kN
    Fuel: Methane/LOX

    After the first stage is burned out, it is thrown off. The second remaining stages bring the BLOOSTAR to an altitude of 400 kilometres in 230 seconds, and the inertial speed increases to 4.4 km/s.

  • Separation 2nd Stage

    Total weight 2nd stage: 701 kg
    (inertia mass 97 kg, fuel mass 604 kg)
    6 rocket engines with a full thrust in vacuum of 2kN
    Fuel: Methane/LOX

    After the separation of the 2nd stage from the 3rd stage, the 3rd stage now alone brings the system to an altitude of 600 kilometres in 340 seconds. The inertial speed is increased to 6.8 km/s.

    After the stage has reached the flight altitude, it corrects the flight path in several ignitions, and the speed is just below the target speed for orbit.

  • Separation 3rd Stage

    Total weight 3rd stage: 400 kg
    (inertia mass 80 kg, fuel mass 320 kg)
    1 rocket engine with a thrust of 2kN in a vacuum
    Fuel: Methane/LOX

    After adjustments for the track height have been made with the help of the 3rd stage, the payload is separated from the 3rd stage.

  • satellite orbit insertion

    The satellite was brought into its orbit position with the help of the BLOOSTAR and can now begin its work.

    The 3rd stage now ignites a third time after the satellite has been set free at a distance to go into a de-orbit mode to minimise the debris of the mission.

The Bloostar

The Shortcut to Orbit

A revolutionary way to go to space, that is BLOOSTAR.

Space has always been a source of inspiration and a place where passion for adventure is born — a place to reach beyond our imagination.

Zero2Infinity is a Spanish company that accesses space in a whole new way. The inflated balloon effortlessly ascends through the thick layers of air, where traditional methods require sophisticated engineering and extra energy to reach the edge of space.

The BLOOSTAR will be transported to an altitude of 22 km, then it will be stopped, and it will release. BLOOSTAR ignites its engines once its above 99% of the air. In near space, within this quasi-vacuum environment, the launcher's efficiency is enhanced and rapidly gains momentum and altitude. The mission of the BLOOSTAR is to simplify access to Space for all humankind, from anywhere – anytime.

BLOOSTAR is a game-changer with a different risk profile creating a new horizon of possibilities. Your satellite volume and the surface of its equipment no longer have the limitations found in conventional launchers.

BLOOSTAR propels into orbit once it's in near space, it's the most environmentally friendly launcher ever designed. Only when it's high above the atmosphere will it release some helium, water and a bit of Carbon Dioxide (CO2).

BLOOSTAR is a smooth ride; there are no strong vibrations, shocks or expensive qualification constraints for your satellite. BLOOSTAR fulfils your mission on demand, into the exact orbit you require. BLOOSTAR takes your payload into orbit with expediency and reliability, enabling hundreds of applications for Earth observation, big data, security, connectivity and science.

Your dedicated and competitive launcher for nano and microsatellites – is BLOOSTAR, by Zero2Infinity!

Why should I use the BLOOSTAR to launch my satellite?

BLOOSTAR is a dedicated nano and microsatellite launching system that will put payloads of 75kg into a 600 km Sun-Synchronous Orbit. It is based on the Rockoon method: an orbital launcher which is ignited from a balloon platform in near-space at an altitude of 20km (65,000ft).

The Rockoon method efficiently substitutes the first stage of a conventional rocket with a Helium balloon ascent to avoid flying through the denser parts of the atmosphere at high velocities. This approach opens up a world of benefits unique for a Rockoon.

Having already mastered stratospheric balloon missions, the next natural step for Zero2Infinity is to build upon this expertise and develop the BLOOSTAR launch vehicle. It is designed with simplicity in mind to ensure lower development and operational costs.

Client Advantages

  • Cheapest dedicated Nanosat launch vehicle on the market.
  • Availability: Lower risk of launch delay due to bad weather (the wind is compensated by the ship's course).
  • Most unproblematic vibration and shock environments.
  • Use of a lighter spacecraft structure.
  • Reduced need for costly and time-consuming market launch qualification tests.
  • Double payload volume.
  • ITAR-free launch.
  • Ability to launch from multiple locations around the world.

The BLOOSTAR Program

For small satellites (<200 kg) there is an apparent increase - in a period of only one year, the four-year forecast for the launch of satellites was raised by 400%.

The increase in the performance of microsatellites has created the conditions for impairment in the space industry. With better performance and lower costs, microsatellites can open the door to a broader range of institutions and enable them to deliver better solutions for our knowledge-based societies. For this to happen, thenecessary instruments will be created to allow for microsatellites to fully exploit their potential with a unique microsatellite launcher.

With BLOOSTAR, we simplify access to space so that space problems can be reduced and solved efficiently. The use of a hybrid balloon rocket solution (a "Rockoon") is efficient, Bloostar uses a stratospheric balloon as the first ascent stage, followed by three rocket stages to reach orbit. The balloon launch platform can be installed on many standard ships, eliminating the need for a launchpad.

The BLOOSTAR delivers the rocket stage to a near-space environment, allowing the significant advantages to be exploited. Bloostar thus utilises the atmosphere and gravity (by buoyancy) and becomes an elegantly efficient solution for affordable and responsive space transport for micro and nano payloads.

Customer Relations

Each client will work closely with a Zero2Infinity Mission Manager and us to achieve the goals and facilitate communication between the parties. The Mission Manager coordinates the entire mission; he/she is responsible for the integration of the purpose.

That includes analysis, documentation results, planning of integration meetings/reports and coordination of all integration and testing activities related to the mission.

The Mission Manager is also in contact with the technical staff and all related staff, licensing agencies to ensure a successful mission.

The Mission Manager will also continuously provide information to the client during the launch campaign to provide personal insight and ensure compliance.

The main focus here is to achieve absolute customer satisfaction.
