Sanaa, Yemen – The United Nations-recognised Yemeni government and the Houthi group have been using warplanes, missiles, drones and other weapons as they engage in intense fighting on multiple fronts in the country’s north, west and central regions.

At least 194 people have been killed and 880 others wounded in the past two weeks of fighting in parts of Taiz, the western coast, al-Jawf, Marib and Dhalea, according to aid agencies.

Iran-backed Houthis, also known as Ansar Allah (supporters of God), have intensified attacks on the coastal district of al-Makha (Mocha) located on the western coast, among others, to gain a foothold in the Red Sea – a vital shipping lane.

On the other hand, government forces have been battling to expand in Taiz and boost their control of Marib, an oil-producing region in the north.

Fighting has also been raging in the al-Jawf governorate bordering Saudi Arabia and Dhalea, which connects the Houthi-controlled north to the country’s south under the internationally recognised government.

Experts say gains or losses on any of these strategically important fronts could have significant consequences for either side.

Taiz and western coast fronts

“The hills and mountainous areas of Taiz and the western coast are key targets for the Houthis, who have repeatedly attempted to advance there,” Yazeed al-Jeddawy, the research manager at the Sanaa Center for Strategic Studies, said.

“The Houthis are trying to seize commanding terrains, cut supply routes between the coastal Mocha district and Taiz, and prevent government troops on the western coast from linking up with the Taiz Military Axis,” said al-Jeddawy.

In Taiz and along the western coast, al-Jeddawy says, the immediate contest is over the heights and roads connecting Taiz to al-Makha.

Situated roughly 60km (37 miles) from the Bab al-Mandeb strait, al-Makha enjoys a highly strategic position on the Red Sea. For a month now, the Houthis have launched missile and drone attacks on the city, causing massive damage to its port facilities and killing and injuring several civilians.

Recently, the group has also attempted to extend its ground operations towards al-Makha city.

“The Houthis seem intent on tightening their hold around [al-Makha] and moving closer to the Dhubab–Bab al-Mandeb area. A substantial advance would strengthen their position near the southern entrance to the Red Sea and give them greater leverage over international shipping,” he added.

Fuad Mussed, a Yemeni political analyst and author, told Al Jazeera that the strategic importance of the western coast and Taiz fronts stems from their proximity to Bab al-Mandeb, a chokepoint connecting the Red Sea to the Gulf of Aden and one of the world’s most important shipping routes.

“The Houthis seek to move closer to this vital waterway to threaten maritime traffic. Such a move aims to keep the Strait of Hormuz and Bab al-Mandeb under the influence of Iran and use them as leverage against regional and international powers. This is a strategy Tehran has been pursuing for years,” Mussed said.

Iran has blocked the Strait of Hormuz, a global oil chokepoint, to use it as leverage in the war against the United States. It has also warned that its allies could shut shipping via Bab al-Mandeb. Iran also attacked Saudi Arabia’s pipeline used to export oil from the Red Sea.

In July, the Houthis declared a blockade against Saudi vessels transiting through the Red Sea – an alternative to the Strait of Hormuz.

Marib and al-Jawf fronts

Over the past few weeks, pro-government forces have attacked Houthi-held territories in Marib and al-Jawf, facing further retaliation from the Houthis.

Saddam al-Huraibi, a Yemeni political commentator, said the Marib front is fateful for both sides.

“Marib is a government stronghold in north Yemen. So, a Houthi expansion in Marib would threaten government presence and weaken its leverage in the north. That is why pro-government troops are ready to fight tooth and nail on this front line,” al-Huraibi told Al Jazeera.

For the Houthis, the takeover of Marib will deepen the group’s authority and step towards controlling the oil and gas infrastructure. The Iran-backed group captured vast swaths of northern Yemen, including the capital, Sanaa, in 2014, but Marib has remained in government hands since.

“Dominating Marib’s oil and gas resources has been a Houthi goal for over a decade. Without facing a crushing defeat in Marib, they would keep fighting to achieve that goal,” al-Huraibi said.

Adjacent to Marib, al-Jawf is also a hub of tense fighting between the Houthis and government forces. A government gain there would lay the groundwork for further advances, while a strong Houthi defence could undermine government forces’ morale and prompt them to retreat.

“Government-aligned forces have lately focused much of their offensive effort on al-Jawf. Government gains in al-Jawf would ease the threat to Marib while requiring the Houthis to defend a much broader area,” al-Huraibi said.

Al-Jeddawy said government gains could open routes towards the north – Saada, Amran or Houthi positions north of Marib.

The Houthis have carried out attacks in Saudi Arabia, including energy facilities in the country’s south. They have also accused Saudi Arabia of launching multiple attacks in al-Jawf, al-Bayda, Marib and Taiz provinces in support of government forces.

The Dhalea front

Fighting on the Dhalea front, a strategic gateway between Houthi-held territory and the southern governorates, has intensified in recent weeks.

Fighting there did not fully stop during the relative calm, which began in April 2022 following the UN-brokered ceasefire.

A Houthi advance there could open a route for their fighters to reach other southern territories. On the other hand, a Houthi setback would encourage government forces to push towards Ibb, controlled by the group.

“[Houthi] advances in Dhalea could expose the southern hinterland, while [government advances] could threaten Houthi positions and supply routes towards Ibb, al-Bayda and, farther north, Sanaa,” al-Jeddawy noted.

With the escalating fighting, the Houthis face pressure on several fronts, but the group has been readying for a range of scenarios, Khaled Ghorab, a pro-Houthi general, said.

“The [Houthi] Yemeni armed forces were never caught off guard by the prospect of escalation; rather, they worked to build and develop their own military capabilities based on tactical combat plans designed to counter a comprehensive, sustained attack launched simultaneously from land, sea and air,” he said.

Ghorab noted that this state of readiness enables the Houthi forces to carry out a direct response to sources of the threat – whether deep within enemy territory or at sea – targeting military bases or aircraft carriers as far as the Horn of Africa.

While the warring parties compete to seize strategic positions on several front lines, the latest escalation is also closely related to the wider regional confrontation.

“Iran has an interest in keeping Yemen and the Red Sea active as sources of leverage, while parts of the government camp believe the Houthis are under growing strain and that this is an opportunity to weaken them,” al-Jeddawy, the Sanaa-based researcher, said.

“The escalation still reflects domestic military and political aims, but its timing and direction cannot be separated from the regional war,” he told Al Jazeera.

China is set to launch its Chang’e-7 unmanned, robotic space mission, possibly as early as Monday morning, to look for ice water in the permanently shadowed craters of the moon’s south pole.

This marks China’s seventh and most ambitious moon mission so far. Here is what we know about it.

What do we know about Chang’e-7?

The Chang’e‑7 launch window runs from Monday, August 24 to Monday, August 31, according to launch observers. That means the mission could lift off on any day in that period.

The Chang’e-7 comprises an orbiter, a lander, a rover and a hopper.

• The orbiter is the main spacecraft which will remain in the moon’s orbit, mapping the surface and taking images while the mission is under way. It will also relay data and communications between the other Chang’e‑7 components and Earth.
• The lander is the vessel that will touch down on the lunar surface, loaded with the necessary scientific instruments for lunar exploration, near the edge of the Shackleton Crater, a 21km-wide (13-mile-wide) pit close to the moon’s south pole. Lunar missions before this have never come this close to the pole.
• The rover is a small robotic vehicle which can drive around the landing site and which carries equipment to analyse the local environment, including rocks and soil.
• The hopper is a small robotic craft powered by solar energy, designed to “hop” – or fly – short distances from the surface of the moon and land again. It will be used to explore the Shackleton Crater.

How do we know there is water on the moon?

Over the past two decades, several space missions have established that there is water on the moon.

Since the 1960s, even before the first Apollo landing in 1969, scientists speculated that water could exist on the moon. However, when Apollo crews returned samples for testing in the late 1960s and early 1970s, they appeared to be dry.

Finally, in 2009, NASA deliberately crashed a rocket segment and its probe into a shadowed lunar crater to analyse the dust plume it kicked up. This provided one of the clearest direct confirmations that significant ice water does exist on the moon, building on earlier detections of water and hydrogen by probes.

In October 2020, NASA scientists announced that water on the moon is more widespread than previously known. They said water molecules had been found to be encapsulated within mineral grains on the lunar surface and speculated that more water is hidden in ice patches which are in permanent shadows.

NASA describes these permanent shadows as dark areas inside deep craters near the north and south poles of the moon where sunlight has not reached for millions or even billions of years. In 2018, prior to confirming it in 2020, NASA had detected water ice in shadowed parts of the moon through mapping.

Why is it important to find out more about the water on the moon?

Expanding knowledge about water on the moon is vital because ancient polar ice may have preserved a record of lunar volcanic activity and of water delivered by comets and asteroids to the Earth-moon system, offering clues to how our own oceans originally formed.

Additionally, if there is enough water on the moon that is realistically accessible, it could serve as a source of drinking water for crewed lunar missions, and could also help to keep equipment cool.

Hydrogen could also be extracted from moon water to provide fuel, while oxygen could be extracted to breathe, supporting onward missions to Mars or lunar mining.

Could anyone ‘own’ the water on the moon?

The 1967 United Nations Outer Space Treaty bans any nation from claiming sovereignty over the moon or owning it as territory. It does not explicitly prohibit commercial operations, but it requires private activities in space to be authorised and supervised by states and leaves key questions about resource ownership unresolved.

Which recent space missions have searched for frozen water on the moon?

In 2023, Russia’s lunar spacecraft, Luna-25, was launched to look for frozen water in the moon’s south pole. However, the Luna-25 spun out of control and crashed. The crash prevented any scientific data collection or water discovery.

Racing against the Luna-25 mission was India’s Chandrayaan-3, which also aimed to expand knowledge of lunar water ice. Chandrayaan-3 successfully landed in August 2023 and found critical new evidence of water on the surface of the moon’s south pole through soil temperature readings.

Why is exploring the moon’s south pole a challenge?

Attempted landings at the moon’s south pole have failed before because of its challenging terrain, which is full of craters and deep trenches.

The south pole is far from the equatorial region targeted by previous missions, including the crewed Apollo landings.

What is different about the Chang’e-7 mission?

The upcoming Chang’e-7 is aiming to expand knowledge about where, exactly, water is located in the craters of the moon, how deep it is, what form it is in and whether it is indeed possible to access it.

The Chang’e-7’s six-legged hopper has been designed to jump into and out of the deep, shadowed craters near the south pole that are hard for traditional rovers to reach, to look for water ice and other resources.

No previous space mission has used a dedicated hopper to jump in and out of lunar craters in this way.
