China's burgeoning space program plans to place astronauts on the moon before 2030 and expand the country's orbiting space station, officials said Monday.

Monday's announcement comes amid against the background of a rivalry with the U.S. for reaching new milestones in outer space, reflecting their competition for influence on global events.

Towering a couple of hours from one of the world's largest cities, the Popocatepetl volcano has been coating nearby towns with ash and disrupting flights at Mexico City's airport, the busiest in Latin America.

Hundreds of explosions have spit lava from the snow-tipped peak of the 17,797-foot Popocatepetl (puh-puh-ka-TEH-pet-tl). Approximately 25 million people live within 60 miles of the mountain. Volcanologists say that, while a massive eruption doesn't appear imminent, eruptions are likely to continue, as they have for three decades.

Typhoon Mawar was a Category 4 super typhoon with maximum sustained winds of 150 mph (241 kph) or greater when it crossed the northern tip of Guam on Wednesday night. It was the strongest typhoon to hit the U.S. Pacific territory since 2002.

A few commonly used weather terms and their definitions, which rely on material from the National Weather Service:

Sea urchins in Israel's Gulf of Eilat have been dying off at an alarming rate, researchers announced Wednesday — a development that threatens the Red Sea's prized coral reef ecosystems.

According to Tel Aviv University scientists, an unknown pathogen is killing off the black sea urchin, Diadema setosum. The massive die-off first began in the eastern Mediterranean Sea, from where it has spread to the neighboring Red Sea, the scientists said.

Saudi Arabia's first astronauts in decades rocketed toward the International Space Station on a chartered multimillion-dollar flight Sunday.

SpaceX launched the ticket-holding crew, led by a retired NASA astronaut now working for the company that arranged the trip from Kennedy Space Center. Also on board: a U.S. businessman who now owns a sports car racing team.

After decades on the sidelines, African countries are venturing into the space industry, hoping to reap rewards in agriculture, disaster prevention and security.

A Japanese company's spacecraft apparently crashed while attempting to land on the moon Wednesday, losing contact moments before touchdown and sending flight controllers scrambling to figure out what happened.

More than six hours after communication ceased, the Tokyo company ispace finally confirmed what everyone had suspected, saying there was "a high probability" that the lander had slammed into the moon.

A Japanese company is about to attempt what no other private business has done: land on the moon.

Tokyo's ispace company put its own spacecraft into orbit around the moon a month ago. On Tuesday, flight controllers will direct the craft, named Hakuto, Japanese for white rabbit, to descend from 60 miles (100 kilometers) high and land.

A spacecraft around Mars has sent back the most detailed photos yet of the red planet's little moon.

The United Arab Emirates' Amal spacecraft flew within 62 miles (100 kilometers) of Deimos last month and the close-up shots were released Monday. Amal — Arabic for Hope — got a two-for-one when Mars photobombed some of the images. It was the closest a spacecraft has been to Deimos in almost a half-century.

Under a cloudless sky, 20,000 eclipse chasers crowded a tiny outpost to watch a rare solar eclipse plunge part of Australia's northwest coast into brief midday darkness Thursday while temporarily cooling the tropical heat.

The remote tourist town of Exmouth, with fewer than 3,000 residents, was promoted as one of the best vantage points in Australia to see the eclipse that also crossed remote parts of Indonesia and East Timor.
