iRocket (Innovative Rocket Technologies Inc) is a startup based in New York, founded in 2018, which develops rocket engines and a small reusable launch vehicle named Shockwave. [1] [2] In 2021 iRocket signed a Space Act Agreement With NASA's Marshall Space Flight Center to accelerate the development of its reusable rocket engine.

The European Space Agency (ESA) is working with companies like Rocket Factory Augsburg, The Exploration Company, ArianeGroup and Isar Aerospace to develop reusable rocket technology. Virgin Galactic’s SpaceShipTwo is designed forsuborbital space tourism, offering passengers a unique space travel experience.
SpaceDev's suborbital Dream Chaser will use internal hybrid rocket motors similar to those SpaceDev developed for Paul Allen's SpaceShipOne, while the orbital version will use the internal motors plus larger external hybrid motors. SpaceDev's hybrid rocket technology was pioneered by the American Rocket Company.
In March 2010, ISRO conducted the flight testing of its new sounding rocket: Advanced Technology Vehicle (ATV-D01), weighing 3 tonnes at lift-off, a diameter of .56 m (1 ft 10 in), and a length of ~10 m (33 ft). [7] It carried a passive scramjet engine combustor module as a test-bed for demonstration of air-breathing propulsion technology. [8]
For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...
In 2018, Rocket Lab began to develop reusable first stage technology, [61] after previously stating publicly that they had no intention of attempting to recover and reuse their launch vehicles. [62] They disclosed the effort to study the potential recovery of an Electron first stage in August 2019, aiming to use a parachute and mid-air ...
Despite the promising technology, the company faces several challenges. The brightness of satellites like BW3 could potentially interfere with astronomical observations.
