.css-14iz86j-BoldText{font-weight:bold;}A rocket built by Amazon founder Jeff Bezos’ space company has tested technology designed to return humans to the Moon in 2024.

The New Shepard rocket, developed by Blue Origin, can land vertically on the ground after returning from space.

The rocket was carrying sensors, a computer and software designed to help space vehicles perform precision landings on other planetary bodies.

Nasa wants to see how it performs here on Earth before it’s sent to the Moon.

Tuesday’s test launch was the seventh for Blue Origin’s New Shepard vehicle, which is designed to carry space tourists on short “sub-orbital” trips.

Congratulations to @blueorigin on another successful #NewShepard mission, completing the first integrated test of our precision landing technologies. Our engineers look forward to analyzing the data and preparing for the next flight!Rewatch the launch: https://t.co/lEM9jyKPim pic.twitter.com/I1XWtna2pf

It will eventually take passengers up to around 100km (60 miles) above the Earth, allowing them to experience microgravity. They will be carried up in a crew capsule mounted on top of New Shepard.

This pressurised capsule features the largest windows ever sent into space, according to the company. After reaching space, the capsule separates from the booster and both vehicles fall to Earth.

During Tuesday’s test (known as NS-13), the capsule gently parachuted down, while the rocket performed a perfect vertical landing.

“Today’s flight was inspiring. Using New Shepard to simulate landing on the Moon is an exciting precursor to what the Artemis programme will bring to America,” said Bob Smith, Blue Origin’s chief executive.

The payload it was carrying for Nasa is called Splice, which stands for Safe and Precise Landing – Integrated Capabilities Evolution.

It consists of two sensor systems, a computer and advanced algorithms – sets of instructions designed to be implemented by a computer.

The purpose of sending it up on New Shepard was to test how the different elements of the payload work together.

“We’re taking the best of Nasa sensor developments across the agency, one or two commercial offerings, putting them on the propulsion module of New Shepard,” said Stefan Bieniawski, senior engineer at Blue Origin.

“What’s really valuable about the propulsion module is coming all the way back from space and doing a propulsive landing, which is very akin to what we want to do with the lunar landing.”

The first of the Splice sensor systems was developed by Draper, a research organisation based in Cambridge, Massachusetts. It’s designed to perform “terrain relative navigation”, in which cameras gather real-time information about the surroundings, which is then compared with pre-loaded maps to determine the vehicle’s precise location.

Because Nasa only had low-resolution maps of the Moon back in the 1960s, Neil Armstrong and Buzz Aldrin almost came down in a boulder field during the historic Apollo 11 landing.

The space agency wants to avoid something like this happening again, so sensor systems like Draper’s are intended to make landings safer.

“[Apollo’s] landing target was on the order of miles, our landing target is 100 metres – or less,” said Stefan Bieniawski.

The second sensor system is called a Navigation Doppler Lidar, which was developed at Nasa’s Langley Research Center in Virginia. It is also designed to help vehicles land precisely, but instead sends laser beams to the surface of the planetary body and detects the reflected signal to determine the vehicle’s velocity and altitude.

Blue Origin is part of a team that was awarded a Nasa contract to start developing a lander capable of returning humans to the lunar surface for the first time since 1972.

Under its Artemis programme, Nasa plans to send a man and a woman to the lunar South Pole. But that would be just an early step in a bigger plan to establish a long-term presence on the Moon.

The 18m-tall New Shepard rocket blasted off at 14:36 BST (09:36 EDT) on Tuesday from Blue Origin’s test facility near Van Horn, Texas. The vehicle reached a maximum altitude of 105km (346,000ft) above the ground.
