SSTO does away with the rocket stages of conventional space flight — where rockets containing engines and fuel and are dropped during ascent to shed weight — instead favoring a fully reusable ...

Called the X-33, it was based on a concept called SSTO — or “single stage to orbit.” SSTO does away with the rocket stages of conventional space flight — where rockets containing engines ...

You see, Saturn V, the most powerful and largest rocket ever made by that time, was 363 feet (110 meters) tall, had a diameter of 33 feet (10 meters), and a mass of up to 6.5 million pounds (2.9 ...

The big challenge with a single-stage-to-orbit, or SSTO, rocket is that achieving the speeds necessary for orbit—around 17,000 mph—requires a lot of propellant.

A SSTO powered by even our most efficient chemical rocket engines would require that the vast majority of its mass be dedicated to propellants, with its structure and payload being tiny in comparison.

ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests. Designed to power the world's first operational Single-Stage-To-Orbit (SSTO) satellite launcher ...

ARCA Space Corporation is developing the world's first SSTO launch vehicle that can deliver both a small payload and itself into low Earth orbit at a cost of about US$1 million per launch. The ...

Arca has unveiled a Single Stage to Orbit (SSTO) rocket dubbed ‘Haas 2CA’ that the firm claims can launch 100 kg (220lbs) of payload to low Earth orbit – and can get there in less than 5 mins.

The rocket engine in question is being developed by British company Reaction Engines Limited. Boeing and Rolls-Royce have invested a total of nearly $38 million in this company.

The big challenge with a single-stage-to-orbit, or SSTO, rocket is that achieving the speeds necessary for orbit—around 17,000 mph—requires a lot of propellant.

Why do these guys think a 20% reduction in oxidizer is going to revolutionize space travel? Most of the cost of launch is the rocket and related infrastructure. The propellant is a small fraction ...
