HOUSTON (AP) \u2014 The\u00a0Artemis II astronauts\u00a0are already the champions of a fresh\u00a0new era of lunar exploration. Now it\u2019s time to set a new distance record.<\/p>\n
Launched last week on\u00a0humanity\u2019s first trip to the moon\u00a0since 1972, the\u00a0three Americans and one Canadian\u00a0are chasing after\u00a0Apollo 13\u2019s maximum range from Earth. That will make them our planet\u2019s farthest emissaries as they swing around the moon without stopping on Monday and then hightail it back home.<\/p>\n
Their roughly six-hour lunar flyby promises views of the moon\u2019s far side that were too dark or too difficult to see by the 24 Apollo astronauts who preceded them. A total solar eclipse also awaits them as the moon blocks the sun, exposing snippets of shimmering corona.<\/p>\n
\u201cWe\u2019ll get eyes on the moon, kind of map it out and then continue to go back in force,\u201d said flight director Judd Frieling. The goal is a moon base replete with landers, rovers, drones and habitats.<\/p>\n
A look at Artemis II’s up-close and personal brush with another world \u2014 our constant companion, the moon.<\/p>\n
Apollo 13\u2019s astronauts missed out on a moon landing when one of their oxygen tanks ruptured on the way there in 1970.<\/p>\n
With the three lives in jeopardy, Mission Control pivoted to a free-return lunar trajectory to get them home as fast and efficiently as possible. This routing relies on the gravity of Earth and the moon, and minimal fuel.<\/p>\n
It worked for Apollo 13, turning it into NASA\u2019s greatest \u201csuccessful failure.\u201d (For the record, flight director Gene Kranz never uttered \u201cFailure is not an option.\u201d The line is pure Hollywood, originating with the 1995 biopic starring Tom Hanks.)<\/p>\n
Commander Jim Lovell, Fred Haise and Jack Swigert reached a maximum 248,655 miles (400,171 kilometers) from Earth before making their life-saving U-turn on Apollo 13.<\/p>\n
Artemis II\u2019s astronauts are following the same figure-eight path since they are neither orbiting the moon nor landing on it. But their distance from Earth should exceed Apollo 13\u2019s by nearly 3,400 miles (5,400 kilometers).<\/p>\n
Artemis II\u2019s Christina Koch said late last week that she and her crewmates don\u2019t live on superlatives, but it\u2019s an important milestone \u201cthat people can understand and wrap their heads around,\u201d merging the past with the present and even the future when new records are set.<\/p>\n
During the flyby, the astronauts will split into pairs and take turns capturing the lunar views out their windows with cameras. At closest approach, they will come within 4,000 miles (6,400 kilometers) of the moon.<\/p>\n
Because they launched on April 1, the rendezvous won\u2019t have as much of the far lunar side illuminated as other dates would have. But the crew still will be able make out \u201cdefinite chunks of the far side that have never been seen\u201d by humans, said NASA geologist Kelsey Young, including a good portion of Orientale Basin.<\/p>\n
They\u2019ll call down their observations as they photograph the gray, pockmarked scenes. There’s a suite of professional-quality cameras on board, and each astronaut also has an iPhone for more informal, spur-of-the-minute picture-taking.<\/p>\n
Young\u2019s team made lunar geography flashcards for the astronauts to study before the flight.<\/p>\n
\u201cThey\u2019ve practiced for many, many, many months on visualizations of the moon,\u201d she said over the weekend, \u201cand getting their eyes on the real thing, I\u2019m really, really looking forward to them bringing the moon a little closer to home on Monday.\u201d<\/p>\n
The upside of the April 1 launch is a total solar eclipse. The eclipse won\u2019t be visible from Earth \u2014 only from the Orion capsule \u2014 treating the astronauts to several minutes\u2019 worth of views of the sun’s outermost, radiating atmosphere, the corona.<\/p>\n
The astronauts will be on the lookout for any unusual solar activity during the eclipse, Young said, and will use their \u201cunique vantage point\u201d to describe the features of the solar corona, or crown.<\/p>\n
All four astronauts packed eclipse glasses to protect their eyes.<\/p>\n
Orion will be out of contact with Mission Control for nearly an hour when it\u2019s behind the moon. The same thing happened during the Apollo moonshots.<\/p>\n
NASA is relying on its Deep Space Network to communicate with the crew, but the giant antennas in California, Spain and Australia won\u2019t have a direct line of sight when Orion disappears behind the moon for approximately 40 minutes.<\/p>\n
These communication blackouts were always a tense time during Apollo although, as Frieling points out, \u201cphysics takes over and physics will absolutely get us back to the front side of the moon.\u201d<\/p>\n
Once Artemis II departs the lunar neighborhood, it will take four days to return home. The capsule will aim for a splashdown in the Pacific near San Diego on April 10, nine days after its Florida launch.<\/p>\n
During the flight back, the astronauts will link up via radio with the crew of the orbiting International Space Station. This is the first time that a moon crew has colleagues in space at the same time and NASA can\u2019t pass up the opportunity for a cosmic chitchat. The conversation will include both members of the first all-female spacewalk in 2019: Koch aboard Orion and Jessica Meir, on the station.<\/p>\n","protected":false},"excerpt":{"rendered":"
