Nasa will make repairs to its latest Moon rocket to prepare for a launch later this year.
The 101-metre Space Launch System, the most powerful yet built, underwent a crucial test on June 20, with results the US space agency is satisfied with.
It will be rolled back to the Vehicle Assembly Building from a launch pad in Florida’s Kennedy Space Centre on July 1 or July 2.
Engineers will spend six to eight weeks preparing the rocket and the Orion spacecraft for launch as part of the Artemis 1 mission, which involves an uncrewed test flight to the Moon.
But first, they have to fix a hydrogen leak.
During an online media briefing on Friday, Nasa officials said they were on track for a launch attempt in late August.
“We have completed the rehearsal phase, and everything we've learnt will help improve our ability to lift off during the target launch window,” said Tom Whitmeyer, deputy associate administrator for common exploration systems at Nasa headquarters.
“The team is now ready to take the next step and prepare for launch.”
During the test, the rocket was fuelled and a practice countdown was held in a process known as a wet dress rehearsal.
Most of the objectives were met, but 13 out of 128 commanded functions were not successfully accomplished and the countdown ended 20 seconds short.
This was the fourth test. Three previous in April also failed because of a hydrogen leak.
Before returning to the Vehicle Assembly Building, engineers will carry out one more test on the rocket’s hydraulic power unit on Friday night to provide additional data for the countdown schedule.
“Once inside the [building], teams will replace a seal on the quick disconnect of the tail service mast umbilical to address a liquid hydrogen leak detected during the rehearsal,” Nasa said on its website.
“Nasa plans to return SLS and Orion to the pad for launch in late August and will set a specific target launch date after replacing hardware associated with the leak.”
The space agency has set several prospective launch dates from late August until June 2023.
This is the first of many missions under the Artemis programme, which aims to build a sustainable human presence on the Moon.
The launch of Artemis 2 is planned for 2024 and includes a crewed mission that will orbit the Moon.
Artemis 3, the first human lunar landing mission under the programme, has been delayed until 2025.
How Alia's experiment will help humans get to Mars
Alia’s winning experiment examined how genes might change under the stresses caused by being in space, such as cosmic radiation and microgravity.
Her samples were placed in a machine on board the International Space Station. called a miniPCR thermal cycler, which can copy DNA multiple times.
After the samples were examined on return to Earth, scientists were able to successfully detect changes caused by being in space in the way DNA transmits instructions through proteins and other molecules in living organisms.
Although Alia’s samples were taken from nematode worms, the results have much bigger long term applications, especially for human space flight and long term missions, such as to Mars.
It also means that the first DNA experiments using human genomes can now be carried out on the ISS.

Thanksgiving meals to try
World Cut Steakhouse, Habtoor Palace Hotel, Dubai. On Thursday evening, head chef Diego Solis will be serving a high-end sounding four-course meal that features chestnut veloute with smoked duck breast, turkey roulade accompanied by winter vegetables and foie gras and pecan pie, cranberry compote and popcorn ice cream.
Jones the Grocer, various locations across the UAE. Jones’s take-home holiday menu delivers on the favourites: whole roast turkeys, an array of accompaniments (duck fat roast potatoes, sausages wrapped in beef bacon, honey-glazed parsnips and carrots) and more, as well as festive food platters, canapes and both apple and pumpkin pies.
Ruth’s Chris Steakhouse, The Address Hotel, Dubai. This New Orleans-style restaurant is keen to take the stress out of entertaining, so until December 25 you can order a full seasonal meal from its Takeaway Turkey Feast menu, which features turkey, homemade gravy and a selection of sides – think green beans with almond flakes, roasted Brussels sprouts, sweet potato casserole and bread stuffing – to pick up and eat at home.
The Mattar Farm Kitchen, Dubai. From now until Christmas, Hattem Mattar and his team will be producing game- changing smoked turkeys that you can enjoy at home over the festive period.
Nolu’s, The Galleria Mall, Maryah Island Abu Dhabi. With much of the menu focused on a California inspired “farm to table” approach (with Afghani influence), it only seems right that Nolu’s will be serving their take on the Thanksgiving spread, with a brunch at the Downtown location from 12pm to 4pm on Friday.

Safety 'top priority' for rival hyperloop company
The chief operating officer of Hyperloop Transportation Technologies, Andres de Leon, said his company's hyperloop technology is “ready” and safe.
He said the company prioritised safety throughout its development and, last year, Munich Re, one of the world's largest reinsurance companies, announced it was ready to insure their technology.
“Our levitation, propulsion, and vacuum technology have all been developed [...] over several decades and have been deployed and tested at full scale,” he said in a statement to The National.
“Only once the system has been certified and approved will it move people,” he said.
HyperloopTT has begun designing and engineering processes for its Abu Dhabi projects and hopes to break ground soon.
With no delivery date yet announced, Mr de Leon said timelines had to be considered carefully, as government approval, permits, and regulations could create necessary delays.
