50余年后人类“重返月球”在即(Artemis II)
“阿尔忒弥斯2号”载人绕月飞行任务
January 2026-For the first time in over half a century,
NASA is set to send astronauts around the Moon. The
agency's Artemis II mission launches no earlier than
February 2026; the first crewed lunar flyby since Apollo
17 in 1972.
Aboard the Orion spacecraft-launched by the massive Space Launch System (SLS) rocket-an international four- person crew will spend about 10 days in deep space. The team comprises three NASA astronauts (including the first woman assigned to a lunar mission) and one Canadian Space Agency astronaut. The fight is a critical dress rehearsal, designed to certify systems for humanity's sustained return to the Moon and beyond.
The mission carries a symbolic artifact: a fabric swatch from the Wright
brothers'1903 Flyer, linking the dawn of powered flight to modern deep-
space exploration. Orion will follow a "free-return trajectory(轨道),"
an inherent safety feature. Lunar gravity will slingshot the craft around
the Moon and back to Earth after launch, ensuring a safe return even if
propulsion(推进)systems fail.
However, the journey has major hazards. Beyond Earth's magnetosphere
(磁层), the crew faces dangerous cosmic radiation and solar flares.
They must also endure 10 days in Orion's confined cabin. Engineers
closely monitor the heat shield, which had unexpected erosion during the
uncrewed Artemis I mission and has since been upgraded. It must withstand extreme atmospheric re- entry heat-any failure would be catastrophic. The crewed life-support system is untested, with no rapid deep- space rescue possible. Communications will be severed for 30 minutes as the craft passes behind the Moon.
Despite these trials, Artemis II is a monumental milestone. It validates technology for future lunar landings and paves the way for future missions to Mars. The world watches as humanity takes this bold step toward a future envisioned since the Apollo era.

信息还原(七选五)
阅读下面短文,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 NASA's Artemis II mission is a key step in humanity's return to lunar
exploration, marking the first crewed lunar flyby in over 50 years since
Apollo 17 in 1972.1_____This 10-day journey, covering more than
600,000 miles, aims to test critical systems for future moon landings.
2_____Named after the Greek goddess of the moon (the twin sister of
Apollo), the mission carries great significance. Unlike previous missions,
Artemis II doesn't plan to land on the moon. Instead, it focuses on verifying
whether the Space Launch System (SLS) rocket and Orion spacecraft can keep astronauts safe in deep space.
A four-person international crew will carry out the mission.3_____ Among them is Christina Koch, who holds the record for the longest single space Bight by a woman. Jeremy Hansen from the Canadian Space Agency will become the first non-US. astronaut to fly to the moon. The crew has named their Orion spa cc craft Integrity."
4_____The launch is scheduled to take place at Kennedy Space Center in Florida, with launch windows in February, March, and April 2026. Before liftoff, NASA will conduct a "wet dress rehearsal" to test fueling and countdown procedures, ensuring all systems work properly.
During the mission, the crew will perform various tasks. They will fly by the far side of the moon, take photos, and conduct scientific experiments.5_____After a three-day return trip, the spacecraft will splash down in the Pacific Ocean, where the U.S. Navy will recover the crew and the capsule.
Artemis II paves the way for Artemis III, which aims to land astronauts near the moon's South Pole. It's a monumental milestone in humanity's quest to explore the moon and beyond.

F. The spacecraft will take three days to reach the moon after launch.
G. Many countries are competing to send astronauts to the moon.
完形填空
NASA's Artemis II mission is set to send four astronauts
on a historic lunar trip as early as February 6. However,
the Orion spacecraft has a known 1_____ in its heat
shield, a crucial part protecting astronauts from extreme
temperatures when the craft re-enters the Earth's atmosphere.
This problem has even led some experts to 2_____ NASA to call off the crewed fight.
The issue comes from a design change of the heat shield. The original Apollo-era shield used a(n) 3_____ honeycomb structure with Avcoat material. For Artemis II, NASA replaced it with large Avcoat blocks to make manufacturing 4_____. But the 2022 uncrewed Artemis I test flight saw chunks of the new shield break off during re-entry, leaving deep holes in the material.
NASA later found the 5_____ cause: the new material was not permeable enough. Gases built up inside during re-entry, 6_____ cracking and damage. Fixing the Artemis II shield was almost 7_____- it had been installed long before Artemis I flew.8_____, NASA chose to adjust the mission's re-entry path to avoid the conditions that 9_____ the damage.
Opinions on the mission's safety are sharply 10_____. Some experts, including former astronaut Danny Olivas, believe NASA has fully 11_____ the problem. They argue the adjusted path and the spacecraft's backup structure will keep the crew 12_____. Artemis II 's commander Reid Wiseman also expressed full confidence in the plan.
13_____, many others remain strongly doubtful. Charlie Camarda, a heat shield expert and former NASA astronaut, is one of the most vocal 14_____. He says NASA's computer models cannot predict all risks and the agency is taking unnecessary chances. He has warned NASA for months, but his advice has so far fallen on 15______ ears.
