SpaceX is looking to make critical improvements to its Mars rocket Starship before its fourth test flight next month.
The two-stage reusable rocket, which consists of the Super Heavy Booster and the Starship spacecraft, reached orbit for the first time during its third test flight in March.
Engineers were also able to show Starship can perform a hypersonic re-entry into Earth's atmosphere, although it ultimately failed as neither the booster nor spacecraft splashed down in the Gulf of Mexico.
They also proved that Starship can open and close its payload door in orbit.
SpaceX carries out the flights from its Starbase launch facilities in Boca Chica, Texas.
Founder Elon Musk said Starship was preparing for its next flight, which would “probably” be in three to five weeks.
“Objective is for the ship to get past max heating or at least further than last time,” the billionaire wrote on X.
Proving Starship can reach orbit, deploy payloads and splash down safely back to Earth would help the company move a step closer to starting commercial operations using the powerful rocket.
Max heating
Max heating is when the spacecraft experiences its highest thermal loads, or intense heat, during re-entry.
As Starship re-enters Earth’s atmosphere at high speeds, friction with atmospheric particles heats the surface of the spacecraft.
Showing that the craft can handle maximum dynamic pressure would prove that it has reliable thermal protection systems.
Starship has more than 18,000 hexagonal heat shield tiles to protect it during re-entry, and SpaceX is likely to carry out improvements to help it survive the extreme temperatures next time.
When the heat shield fails, other parts of the craft can also suffer, including its structural integrity, with possible sensor and system failures and compromised engine performance.
Booster performance
The Super Heavy Booster failed to splash down in March, but it performed significantly better than the first two test flights, in April and November last year.
All of its 33 Raptor engines stayed lit as the Starship spacecraft separated from the booster to accelerate to orbit.
After separation, the booster completed its flip manoeuvre, a critical stage in which the rocket reorients itself for a controlled descent to land.
Ultimately, SpaceX plans to make the Super Heavy Booster reusable and for it to land it on the ground (similar to its Falcon boosters), but for test flights, it carries out a splashdown in the ocean.
It also completed a boostback burn, when the rocket fires its engines to adjust its trajectory and reverse course towards the splashdown site.
Several engines managed to light up during this burn, but it did not complete the splashdown, with a “rapid unscheduled disassembly” or explosion, 462 metres above the Gulf of Mexico.
Three test flights in under a year
However, SpaceX has made significant progress in the development of Starship, completing three test flights in under a year.
It managed to complete a unique technique called hot-staging, in which the spacecraft's engines ignite even before separating from the Super Heavy Booster.
This helps reduce the time and altitude lost between stage separations, ultimately enhancing the vehicle's efficiency in reaching orbit.
The tests have been instrumental in improving the synchronisation of Starship with the Super Heavy Booster, ensuring that the complex systems operate in harmony during critical phases of the flight.
Testing the rocket is also helping engineers to gather more data on its performance, so they can make the necessary adjustments and improve safety and reliability.
SpaceX has a $2.89 billion contract with Nasa to land humans on the Moon.
Starship was selected for the Artemis 3 mission, in which astronauts will attempt a lunar landing in 2026. If successful, it will be the first time people have set foot on the Moon since the final Apollo mission in 1972.
Seats are already sold, including to the Japanese billionaire entrepreneur and art collector Yusaku Maezawa, who plans to take eight artists with him as part of his dearMoon project.
US billionaire Jared Isaacman is also working with SpaceX through his Polaris programme, a series of privately led space missions.
Mr Musk's ultimate goal is to make life multiplanetary and he hopes to land humans on Mars using his Starship fleets.
“SpaceX’s mission is to extend consciousness to Mars and then the stars,” he posted on X on Monday.

Coffee: black death or elixir of life?
It is among the greatest health debates of our time; splashed across newspapers with contradicting headlines - is coffee good for you or not?
Depending on what you read, it is either a cancer-causing, sleep-depriving, stomach ulcer-inducing black death or the secret to long life, cutting the chance of stroke, diabetes and cancer.
The latest research - a study of 8,412 people across the UK who each underwent an MRI heart scan - is intended to put to bed (caffeine allowing) conflicting reports of the pros and cons of consumption.
The study, funded by the British Heart Foundation, contradicted previous findings that it stiffens arteries, putting pressure on the heart and increasing the likelihood of a heart attack or stroke, leading to warnings to cut down.
Numerous studies have recognised the benefits of coffee in cutting oral and esophageal cancer, the risk of a stroke and cirrhosis of the liver.
The benefits are often linked to biologically active compounds including caffeine, flavonoids, lignans, and other polyphenols, which benefit the body. These and othetr coffee compounds regulate genes involved in DNA repair, have anti-inflammatory properties and are associated with lower risk of insulin resistance, which is linked to type-2 diabetes.
But as doctors warn, too much of anything is inadvisable. The British Heart Foundation found the heaviest coffee drinkers in the study were most likely to be men who smoked and drank alcohol regularly.
Excessive amounts of coffee also unsettle the stomach causing or contributing to stomach ulcers. It also stains the teeth over time, hampers absorption of minerals and vitamins like zinc and iron.
It also raises blood pressure, which is largely problematic for people with existing conditions.
So the heaviest drinkers of the black stuff - some in the study had up to 25 cups per day - may want to rein it in.

Top tips
Create and maintain a strong bond between yourself and your child, through sensitivity, responsiveness, touch, talk and play. “The bond you have with your kids is the blueprint for the relationships they will have later on in life,” says Dr Sarah Rasmi, a psychologist.
Set a good example. Practise what you preach, so if you want to raise kind children, they need to see you being kind and hear you explaining to them what kindness is. So, “narrate your behaviour”.
Praise the positive rather than focusing on the negative. Catch them when they’re being good and acknowledge it.
Show empathy towards your child’s needs as well as your own. Take care of yourself so that you can be calm, loving and respectful, rather than angry and frustrated.
Be open to communication, goal-setting and problem-solving, says Dr Thoraiya Kanafani. “It is important to recognise that there is a fine line between positive parenting and becoming parents who overanalyse their children and provide more emotional context than what is in the child’s emotional development to understand.”

What the law says
Micro-retirement is not a recognised concept or employment status under Federal Decree Law No. 33 of 2021 on the Regulation of Labour Relations (as amended) (UAE Labour Law). As such, it reflects a voluntary work-life balance practice, rather than a recognised legal employment category, according to Dilini Loku, senior associate for law firm Gateley Middle East.
“Some companies may offer formal sabbatical policies or career break programmes; however, beyond such arrangements, there is no automatic right or statutory entitlement to extended breaks,” she explains.
“Any leave taken beyond statutory entitlements, such as annual leave, is typically regarded as unpaid leave in accordance with Article 33 of the UAE Labour Law. While employees may legally take unpaid leave, such requests are subject to the employer’s discretion and require approval.”
If an employee resigns to pursue micro-retirement, the employment contract is terminated, and the employer is under no legal obligation to rehire the employee in the future unless specific contractual agreements are in place (such as return-to-work arrangements), which are generally uncommon, Ms Loku adds.

How to turn your property into a holiday home
- Ensure decoration and styling – and portal photography – quality is high to achieve maximum rates.
- Research equivalent Airbnb homes in your location to ensure competitiveness.
- Post on all relevant platforms to reach the widest audience; whether you let personally or via an agency know your potential guest profile – aiming for the wrong demographic may leave your property empty.
- Factor in costs when working out if holiday letting is beneficial. The annual DCTM fee runs from Dh370 for a one-bedroom flat to Dh1,200. Tourism tax is Dh10-15 per bedroom, per night.
- Check your management company has a physical office, a valid DTCM licence and is licencing your property and paying tourism taxes. For transparency, regularly view your booking calendar.
