【Two Couples Affair in Broad Daylight】

A private Japanese space company will try to land an uncrewed robotic spacecraft on Two Couples Affair in Broad Daylightthe moon and deliver a rover to its surface today, after a failed attempt in April 2023. 

Landing on the moon remains onerous— demonstrated by numerous flopped landings. Though Firefly Aerospace succeededin landing in March, another U.S. company, Intuitive Machines, didn't fare as well, ending up on its sidein a crater less than a week later. 

Tokyo company ispacehas been waiting for this day for the so-called Hakuto-R mission for roughly 4.5 months. Its spacecraft, Resilience, was one of two spacecraftheaded to the moon on a SpaceXFalcon 9 rocket in mid-January. Its travel companion, Firefly's Blue Ghost lander, took a faster route and touched down on the surfaceMarch 2. Though Firefly wasn't the trailblazer — the first private robotic lander to make the journey to the surface happened last year — it was the first to get its lander there upright and in one piece.

But ispace's lander has taken a longer journey to save on fuel — and the company knows all too well how crucial that is: After a post-flight investigation, the company said its first lander crashed because it ran out of fuel on the way down, unable to control its landing. 

Here's how to watch the second-chance event.

The Hakuto-R mission is gearing up for a landing near the center of Mare Frigoris, aka the Sea of Cold, at 3:17 p.m. ET on Thursday, June 5(that's 4:24 a.m. on June 6 in Japan).

Livestream coveragewill begin about one hour earlier, at 2:10 p.m. ET, with English translation.

Landing on the moon is difficult because of its exosphere, which provides virtually no drag to slow a spacecraft down as it approaches the ground. What's more, there are no GPS systems on the moon to help guide a craft to its landing spot. Engineers have to compensate for those challenges from 239,000 miles away.
