The lunar flyby would be the deepest humans have traveled in space in decades.

It’s go time for the highest-stakes mission at NASA in more than 50 years.
On April 1, the agency is set to launch four astronauts around the moon, the deepest human spaceflight since the final Apollo lunar landing in 1972.
The launch window for Artemis II , as the mission is called, opens at 6:24 p.m. ET.
National Aeronautics and Space Administration teams have been preparing the vehicles to depart from Florida’s Kennedy Space Center on the planned roughly 10-day trip. Crew members have trained for years for this moment.
Reid Wiseman, the NASA astronaut serving as mission commander, said he doesn’t fear taking the voyage. A widower, he does worry at times about what he is putting his daughters through.
“I could have a very comfortable life for them,” Wiseman said in an interview last September.
“But I’m also a human, and I see the spirit in their eyes that is burning in my soul too. And so we’ve just got to never stop going.”
Wiseman’s crewmates on Artemis II are NASA’s Victor Glover and Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen.
What are the goals for Artemis II?
The biggest one: Safely fly the crew on vehicles that have never carried astronauts before.
The towering Space Launch System rocket has the job of lofting a vehicle called Orion into space and on its way to the moon.
Orion is designed to carry the crew around the moon and back. Myriad systems on the ship—life support, communications, navigation—will be tested with the astronauts on board.
SLS and Orion don’t have much flight experience. The vehicles last flew in 2022, when the agency completed its uncrewed Artemis I mission .
How is the mission expected to unfold?
Artemis II will begin when SLS takes off from a launchpad in Florida with Orion stacked on top of it.
The so-called upper stage of SLS will later separate from the main part of the rocket with Orion attached, and use its engine to set up the latter vehicle for a push to the moon.
After Orion separates from the upper stage, it will conduct what is called a translunar injection—the engine firing that commits Orion to soaring out to the moon. It will fly to the moon over the course of a few days and travel around its far side.
Orion will face a tough return home after speeding through space. As it hits Earth’s atmosphere, Orion will be flying at 25,000 miles an hour and face temperatures of 5,000 degrees as it slows down. The capsule is designed to land under parachutes in the Pacific Ocean, not far from San Diego.
Is it possible Artemis II will be delayed?
Yes.
For safety reasons, the agency won’t launch if certain tough weather conditions roll through the Cape Canaveral, Fla., area. Delays caused by technical problems are possible, too. NASA has other dates identified for the mission if it doesn’t begin April 1.
Who are the astronauts flying on Artemis II?
The crew will be led by Wiseman, a retired Navy pilot who completed military deployments before joining NASA’s astronaut corps. He traveled to the International Space Station in 2014.
Two other astronauts will represent NASA during the mission: Glover, an experienced Navy pilot, and Koch, who began her career as an electrical engineer for the agency and once spent a year at a research station in the South Pole. Both have traveled to the space station before.
Hansen is a military pilot who joined Canada’s astronaut corps in 2009. He will be making his first trip to space.
Koch’s participation in Artemis II will mark the first time a woman has flown beyond orbits near Earth. Glover and Hansen will be the first African-American and non-American astronauts, respectively, to do the same.
What will the astronauts do during the flight?
The astronauts will evaluate how Orion flies, practice emergency procedures and capture images of the far side of the moon for scientific and exploration purposes (they may become the first humans to see parts of the far side of the lunar surface). Health-tracking projects of the astronauts are designed to inform future missions.
Those efforts will play out in Orion’s crew module, which has about two minivans worth of living area.
On board, the astronauts will spend about 30 minutes a day exercising, using a device that allows them to do dead lifts, rowing and more. Sleep will come in eight-hour stretches in hammocks.
There is a custom-made warmer for meals, with beef brisket and veggie quiche on the menu.
Each astronaut is permitted two flavored beverages a day, including coffee. The crew will hold one hourlong shared meal each day.
The Universal Waste Management System—that’s the toilet—uses air flow to pull fluid and solid waste away into containers.
What happens after Artemis II?
Assuming it goes well, NASA will march on to Artemis III, scheduled for next year. During that operation, NASA plans to launch Orion with crew members on board and have the ship practice docking with lunar-lander vehicles that Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin have been developing. The rendezvous operations will occur relatively close to Earth.
NASA hopes that its contractors and the agency itself are ready to attempt one or more lunar landing missions in 2028. Many current and former spaceflight officials are skeptical that timeline is feasible.

Wall Street’s hottest momentum trade has reversed sharply, as former winners tumble and heavily shorted stocks surge.

Wall Street’s hottest trade has gone ice cold.
For years, it paid off to buy stocks that were rising in price—and bet against struggling shares. The momentum trade was especially profitable this year, as investors piled into hot stocks including Micron Technology, Nvidia, Advanced Micro Devices and other artificial-intelligence darlings while wagering against those likely to be hurt by the embrace of AI.
The S&P 500 Momentum Index soared 44% in the second quarter, its best quarterly performance on record, and it surged 133% over the past five years, nearly double the broad market’s performance.
Mega funds and rookie investors alike piled into the trade, some using leverage and options contracts in an effort to amplify their returns, propelling the underlying shares higher.
“It is a self-fulfilling prophecy,” said Matthew Tym, managing director at Cantor Fitzgerald, of the trade.
Suddenly, the trade is a loser. The momentum index has tumbled more than 9% since July 1, lagging behind the S&P 500’s 2.8% gain. The index—which tracks stocks in the S&P 500 based on a “momentum score”—is on track for the biggest quarterly underperformance in 25 years. July was the second-worst month for the momentum trade in around 40 years, according to Bank of America estimates; the only month worse was April 2009, in the teeth of the global financial crisis.
Hedge funds that bought momentum shares while shorting low-momentum stocks suffered even more. At the same time, a basket of the most popular stocks held by hedge funds tracked by Goldman Sachs recorded its biggest one-month underperformance in July relative to the S&P 500 in more than 20 years, according to the bank’s analysts.
Momentum trading is based on a rather simple observation: Investments that go up tend to keep outperforming; those that underperform often remain laggards. This kind of trading might seem too simple a stock-picking strategy to work. Yet it often has.
“For decades, it didn’t take a lot of sophistication to run a momentum strategy and make a decent living at it,” says Agustin Lebron, senior researcher at EquiLibre, a trading firm.
Part of the reason: It takes a while for corporate and other information to spread to various investors, so they slowly build positions, producing buying momentum.
“A huge pension fund can’t flip around its positions in a day,” says Lebron. “Behavioral biases also account for some of the effect, as well—people tend to sell their winners too early and hold losers too long.”
Fans of the strategy point to the human tendency to extrapolate from past results—and chase investment returns—noting that momentum patterns have been evident in markets for decades, even centuries. They also say that some of the worst months for momentum strategies are during longer periods of outperformance.
Some have been doing the trade by buying the strongest investments in a sector while shorting the weakest; others lean in to rising markets or asset classes. Still others use a quantitative approach or turn to banks or others who sell ways to make distinct wagers on momentum as a “tradable factor” or a “thematic basket.”
The fans remain believers. “Any strategy has disappointing periods,” says Antti Ilmanen, global co-head of the portfolio solutions group at AQR Capital Management.
The surge in Moderna and other biotech stocks helped crush the momentum trade. These shares were among the most heavily shorted in recent years, but positive news on a cancer vaccine from Moderna and Merck sent those stocks flying, crushing some quant and other hedge funds. Moderna is up around 150% so far this month.
These traders had an especially rough day on Aug. 19, which Goldman Sachs told its clients was the worst day for “systematic long-short managers” in more than two years. About half of the losses were because of momentum trades, the bank said.
Some traders have begun to short, or bet against, the very stocks that propelled the momentum trade earlier this year. Net short positions in futures tied to the Nasdaq-100 index among speculators recently climbed to some of the highest levels of the past two decades, according to data from the Commodity Futures Trading Commission.
The about-face is a sign of how markets have become more treacherous for investors, even as indexes keep climbing. Part of the issue: the recent meltdown of Situational Awareness, a hedge fund that had piled into some of the most popular momentum shares, including chip stocks. After a period of market tumult, Nvidia shares rocketed almost 9% after its earnings, showing how quickly sentiment can shift.
Some investors say the run-up in share prices driving tech stocks higher reminds them at times of the dot-com frenzy decades ago.
Mike Ogborne, the founder of San Francisco-based Ogborne Capital Management, said he has grown more cautious on technology stocks and is keeping more of his portfolio in cash than he typically does.
And he is nervous about the surge in spending by technology giants and quarterly capital expenditures that keep rising.
“It is a little bit like Cinderella and the clock striking midnight. You don’t know when midnight is going to come around,” Ogborne said. “They don’t send a memo around telling you when the capex cycle is over.”
