Countdown to mission hunting alien life on a distant moon

Published

on

In a few hours, a spacecraft should blast-off from Florida on the hunt for signs of alien life.

Its destination is Europa, a deeply-mysterious moon orbiting the distant planet Jupiter.

Trapped under its icy surface could be a vast ocean with double the amount of water on Earth.

The Europa Clipper spacecraft will chase a European mission that left last year, but using a cosmic piggyback, it will overtake and arrive first.

That won’t be until 2030 but what it finds could change what we know about life in our solar system.

A moon five times brighter than ours

Years in the making, the Europa Clipper launch was delayed at the last minute after hurricane Milton blasted Florida this week.

The spacecraft was rushed indoors for shelter, but after checking the launchpad at Cape Canaveral for damage, engineers have now given the go-ahead for lift-off at 1206 local time (1706 BST) on 14 October.

“If we discover life so far away from the Sun, it would imply a separate origin of life to the earth,” says Mark Fox-Powell, a planetary microbiologist at the Open University.

“That is hugely significant, because if that happens twice in our solar system, it could mean life is really common,” he says.

Located 628m km from Earth, Europa is just a bit bigger than our moon, but that is where the similarity ends.

If it was in our skies, it would shine five times brighter because the water ice would reflect much more sunlight.

Its icy crust is up to 25km thick, and sloshing beneath, there could be a vast saltwater ocean. There may also be chemicals that are the ingredients for simple life.

Scientists first realised Europa might support life in the 1970s when, peering through a telescope in Arizona, they saw water ice.

Voyager 1 and 2 spacecrafts captured the first close-up images, and then in 1995 Nasa’s Galileo spacecraft flew past Europa taking some deeply puzzling pictures. They showed a surface riddled with dark, reddish-brown cracks; fractures that may contain salts and sulfur compounds that could support life.

The James Webb telescope has since taken pictures of what might be plumes of water ejected 100 miles (160 kilometers) above the moon’s surface

But none of those missions got close enough to Europa for long enough to really understand it.

Flying through plumes of water

Now scientists hope that instruments on Nasa’s Clipper spacecraft will map almost the entire moon, as well as collect dust particles and fly through the water plumes.

Britney Schmidt, associate professor of earth and atmospheric sciences at Cornell university in the US, helped to design a laser onboard that will see through the ice.

“I’m most excited about understanding Europa’s plumbing. Where’s the water? Europa has the ice version of Earth’s subduction zones, magma chambers and tectonics – we’re going to try to see into those regions and map them,” she says.

Her instrument, which is called Reason, was tested in Antarctica.

But unlike on Earth, all the instruments on Clipper will be exposed to huge amounts of radiation which Prof Schmidt says is a “major concern.”

The spacecraft should fly past Europa about 50 times, and each time, it will be blasted with radiation equivalent to one million X-rays.

“Much of the electronics are in a vault that’s heavily shielded to keep out radiation,” Prof Schmidt explains.

The spaceship is the largest ever built to visit a planet and has a long journey ahead. Travelling 1.8 billion miles, it will orbit both the Earth and Mars to propel itself further towards Jupiter in what is called the sling-shot effect.

It cannot carry enough fuel to motor itself all the way alone, so it will piggyback off the momentum of Earth and Mars’s gravitational pull.

It will overtake JUICE, the European Space Agency’s spaceship that will also visit Europa on its way to another of Jupiter’s moons called Ganeymede.

Once Clipper approaches Europa in 2030 it will switch on its engines again to carefully manoeuvre itself into the right orbit.

Space scientists are very cautious when talking about the chances of discovering life- there is no expectation that they will find human-like creatures or animals

“We are searching for the potential for habitability and you need four things – liquid water, a heat source, and organic material. Finally those three ingredients need to be stable over a long enough period of time that something can happen,” explains Michelle Dougherty, professor of space physics at Imperial College in London.

And they hope that if they can understand the ice surface better, they will know where to land a craft on a future mission.

An international team of scientists with Nasa, the Jet Propulsion Lab and the Johns Hopkins Applied Physics Lab will oversee the odyssey.

At a time when there is a space launch virtually every week, this mission promises something different, suggests Professor Fox-Powell.

“There’s no profit being made. This is about exploration and curiosity, and pushing back the boundaries of our knowledge of our place in the universe,” he says.

Nigerian mobile network changes name

Published

on

 

Nigerian telecom operator 9mobile formerly Etisalat has changed its name to T2.

The unveiling to a new brand identity was announced during a corporate event tagged Tech Meets Tenacity at Eko Hotels and Suites in Lagos.

The transformation also comes with a new orange colour scheme, replacing the company’s longtime green branding.

The Chief Executive Officer, Obafemi Banigbe, said the move was aimed at redefining the company’s position in Nigeria’s telecom market and competing more strongly in the industry.

The event was attended by key stakeholders, including the Minister of Communications and Digital Economy, Dr. Bosun Tijani, and featured musical performances, with entertainment personality Darey Art Alade as host.

The rebrand marks another chapter in the company’s history.

Originally launched as Etisalat Nigeria, the firm once had over 22 million subscribers before financial challenges and loss of investors reduced its active users to 3.2 million by January 2025.

In recent months, it signed a national roaming agreement with MTN Nigeria to improve coverage and service quality.

The shift from 9mobile to T2 is part of a broader plan to stabilise operations, attract more customers, and remain competitive in Nigeria’s fast-changing telecommunications sector.

Subscribers on MTN and Airtel networks spent a total of N2.53tn on voice and data services in the first half of 2025, representing a 50.9 per cent increase from the N1.68tn recorded in the corresponding period of 2024.

This is according to an analysis of the half-year 2025 results released by both telcos.

The figure reflects rising consumer spending on telecommunications, driven by tariff reviews, increased smartphone penetration and sustained network investment by the two largest mobile network operators in Nigeria.

MTN Nigeria generated N2.12tn in voice and data revenue between January and June 2025, marking a 55.7 per cent increase from the N1.36tn recorded in H1 2024.

The telco’s data revenue surged by 69.2 per cent to N1.23tn, up from N727.33bn in the same period last year.

Voice revenue also grew by 40.3 per cent year-on-year to reach N887.13bn, compared to N632.38bn previously.

The company attributed the performance to robust demand, price adjustments implemented largely in the second quarter, and continued growth in its active data user base.

MTN reported an 11.8 per cent increase in active data subscribers to 51 million, while total mobile subscribers rose by 6.7 per cent to 84.7 million.

Average data consumption per subscriber increased by 26.3 per cent to 13.2 gigabytes, supported by smartphone penetration of 62.6 per cent and a 41.2 per cent rise in data traffic.

The telco also executed a price review across voice and data plans during the period, which boosted service revenue.

The strong topline performance helped MTN swing from a loss of N519.1bn in H1 2024 to a profit after tax of N414.9bn in H1 2025.

Earnings before interest, tax, depreciation and amortisation more than doubled, rising by 119.5 per cent to N1.2tn, with the EBITDA margin improving to 50.6 per cent.

The company has since revised its full-year guidance, forecasting service revenue and EBITDA margin growth of at least 50 per cent.

Airtel Nigeria, meanwhile, recorded a total of $298 million in data and voice revenue during the same six-month period.

Using the exchange rate of N1,384/$ adopted by the company, this amounts to N412.43bn—an increase of 30.1 per cent over the N316.94bn reported in H1 2024.

Airtel’s data revenue grew by 40.2 per cent year-on-year, rising from $117 million (N161.93bn) to $164 million (N226.98bn), while voice revenue rose by 19.1 per cent from $112 million (N155.01bn) to $134 million (N185.46bn).

The growth was underpinned by an 11.3 per cent rise in Airtel Nigeria’s data subscriber base to 29.3 million and a 46.8 per cent increase in data average revenue per user.

Data usage per subscriber climbed to 9.3GB monthly, up from 7.3GB in the previous year, while smartphone penetration rose to 51.4 per cent.

The company’s overall customer base grew by 6.3 per cent to 53.6 million by June 2025 in Nigeria.

Airtel Nigeria’s EBITDA rose by 49.9 per cent year-on-year to $185 million, and its EBITDA margin expanded to 55.7 per cent, supported by strong topline performance and the continuation of its cost efficiency strategy.

Although the company was impacted by currency devaluation in the previous year, its financial position improved in 2025, with increased profitability and stronger operating cash flows.

Both MTN and Airtel noted that macroeconomic conditions had become more stable during the first half of the year.

The Central Bank of Nigeria maintained the monetary policy rate at 27.5 per cent, helping to moderate inflation to 22.2 per cent by June 2025.

The naira also held steady around N1,530 to the US dollar, providing a more favourable environment for financial planning and capital investment.

In his commentary on the H1 result, the CEO of MTN Nigeria, Karl Toriola, said “We maintained strong commercial momentum in H1 2025 through disciplined execution, targeted customer engagement and network investments.

“Our mobile subscribers rose to 84.7 million, with a net addition of 3.8 million in H1; despite the impact of the new SIM registration regulations introduced in Q1. As we increase our effort to add more strategic agents, we anticipate an easing of this headwind as we move forward. Active data users rose by 3.3 million in H1 to approximately 51 million, driving a 41.2 per cent YoY increase in data traffic.

“During the period, we completed the phased implementation of the new price adjustments across voice and data bundles, largely benefiting Q2. Pleasingly, the demand for our services remained resilient, which supported strong service revenue growth in the period.”

MTN said it had launched the first phase of its Dabengwa Tier III Data Centre and was onboarding mobile virtual network operators to its infrastructure, in line with the NCC’s efforts to deepen competition and improve nationwide connectivity.

Toriola noted, “As part of our strategy to expand capacity and meet the growing demand for our services, we launched the first phase of our US$240 million Dabengwa Tier 3 Data Centre in July 2025. This multi-stage data centre project is a world-class facility that will become the largest of its kind in West Africa. It will deliver industry-leading standards of scalability, reliability and security. It will enable businesses to digitise operations, drive innovation and scale efficiently.”

Airtel also highlighted its partnership with SpaceX to deliver Starlink’s high-speed satellite broadband services to remote communities across Africa, including Nigeria.

It noted, “On 5 May 2025, the Company announced an agreement with SpaceX to bring Starlink’s high-speed internet services to its customers in Africa.

“With this collaboration, Airtel Africa will further enhance its next generation satellite connectivity offerings and augment connectivity for enterprises, businesses and socio-economic communities like school, health centres etc in most rural parts of Africa.

“Currently, SpaceX has acquired the necessary licences in nine out of 14 countries within Airtel Africa’s footprint and operating licences for the other five countries are under process.”

The combined N2.53tn spent on telecom services in just six months highlights the critical role played by voice and data connectivity in Nigeria’s economy.

With expanding networks, increasing demand for digital content, and deeper smartphone adoption, telecoms are poised to remain one of the fastest-growing sectors in the country’s post-pandemic recovery.

‘Sorry’ – Elon Musk apologies, addresses Starlink satellite global outage

Published

on

United States of America tech billionaire Elon Musk has apologised after his firm, SpaceX Starlink, a satellite internet provider, suffered a 2.5-hour disruption of high-speed internet service globally on Thursday night.

Musk, in a post via his X account, said he was “sorry” as he addressed the issue.

Recall that SpaceX’s Starlink satellite internet suffered one of its biggest international outages, knocking tens of thousands of users offline.

 

This came as a result of a failure of internal software services.

Reacting, Musk promised that SpaceX will resolve the root cause and make sure it doesn’t happen again in the future.

“Sorry for the outage. SpaceX will remedy root cause to ensure it doesn’t happen again,” Musk wrote.

SpaceX has launched more than 8,000 Starlink satellites since 2020.

In Nigeria, Starlink officially resumed activations for customers nationwide last month.

According to the US firm, high-demand customers in Lagos and Abuja, among other cities, are at the forefront of its revival.

Recall that between October and November last year, Starlink temporarily paused activations of new customers over regulatory approvals.

This followed the internet company, with over 60,000 subscribers, arbitrarily increasing its subscription prices without the Nigerian Communications Commission’s approval in October 2024.
