Japan’s ‘moon sniper’ probe made incredibly accurate landing, but is now upside down
Japan’s ‘moon sniper’ probe made incredibly accurate landing, but is now upside down
Slim probe landed metres rather than kilometres from its target, but a rocket malfunction has left it in an undignified position
They accidentally left it calibrated for an Australian launch.
I think it's pretty impressive they managed to do a soft KSP-style landing without an engine nozzle.
Yeah, that's the bigger deal. They lost an engine and still managed a soft landing. They just landed upside down -- but the solar cells might still work.
And for the record, the lander was supposed to land on its side. It's designed to do a quarter turn just before it touches the ground, but because of a slope, it rolled a little bit further than they wanted.
It was so close to perfect!
It's actually amazingly impressive! In contrast, in the past few years Israel, India and even Russia have had disappointing failures trying to land on the moon - not because they're engineers aren't as good, but because it's just really freaking hard to get right and a lot of unexpected things can happen.
The Japanese team lost an engine nozzle and with it about 40% of their thrust as they were mid landing. Losing 1 out of 2 engines is the kind of critical malfunction that usually dooms a mission (like it did once for India); but regardless, their software was able to adjust on the fly, automatically switch into a different flight mode, and still put the lander exactly where they wanted it.
This is a remarkable success where so many talented others have failed. In a couple of weeks, the sun will be shining from the right direction to hit their solar panels and their mission should continue!
I said the same thing when I crashed my mom's car.
At least it wasn't across 2 spaces
Now they are just waiting for some wind.
Ok so just fire a laser at it to generate power in the solar panels?
Good idea! NASA do actually have a laser that can shine to the moon and back
Fun fact: the average laser's collimation expands to the size of a football field by time it reaches the altitude of the ISS. The moon is 1,000x further. Despite the higher refinement of the laser used to bounce light off the retro reflector, it still takes an incredibly strong sensor to detect the bounce back. It's not how The Big Bang Theory portrays it.
Now that this party is pooped, the sun is still stronger than anything we can beam. It might trickle charge. The rays that decrease exponentially with distance, coming from. 93 million miles away, still roasts us. Solar power is insane.
Edit: astronomers did actually beam a laser and get seen by the ISS. They used a very powerful, focused blue laser and tracking software to aim it on a powered mount. The tracking was necessary because they had to shine it when it was not illuminated. When we see the ISS lit in the night sky, they're in full sun. The astronaut, Don Pettit who has an extensive photo portfolio, reported seeing a dim, flickering blue light coming from the ground and got a picture. He also saw the spotlights flashing. https://www.universetoday.com/93987/amateur-astronomers-flash-the-space-station/
Nevertheless, space officials are describing the mission as a success, despite the fact that the probe, nicknamed the “moon sniper”, appears to have tumbled down a crater slope, leaving its solar batteries facing in the wrong direction and unable to generate electricity.
So it’s like that time the SpaceX booster exploded near its landing craft due to missing it by meters?
I don't know why people insist on trying to diss SpaceX anytime there's space news... Anyway, last time they missed the Autonomous Drone Ship was years ago when they were first trying to land. So I'm not exactly sure what you are referring to.
Plus, with space missions there are usually many different mission objectives, and with this mission the main mission was to "demonstrate its highly precise navigation and landing system" which they determined to be a success. The extra credit mission would be if it landed properly and they were able to do more science with it.
We could send Wallace and Gromit up there to flip it over...
You would think it would be designed to right itself from any orientation.
Why does a country with no ballistic missile program go for this sort of feat? Japan really has the tech base and uranium reprocessing ability to rocket into having ICBMs in no time.
Japan got struck twice with thermonuclear bombs in world war 2, in 2 cities named Hiroshima and Nagasaki. Look it up. They are very much against nuclear arms in general since then.
The populace is, for now. Expansions of the JDF and general worldwide rise in nationalism with Korea going nuclear, the decline of America and China being aggressive off of the Ryukyu islands can change that quite rapidly. I looked it up and there's general consensus that they can build ICBMs in 6 months with their 9 ton stockpile of plutonium and enriched uranium and using their rockets off the shelf, if they haven't already just secretly built the warheads and stored them.
Seems Abe had historically made noises in the general direction that having nuclear weapons wouldn't be against the constitution as well. Very Japanese to have a face of nonproliferation and peacefulness while also positioning themselves with a full nuclear deterrent in their back pocket.
Edit: Also, those bad boys were simple fission bombs. Thermonuclear usually refers to fusion weapons. 6 month estimate would be a fission weapon boosted with tritium to increase the neutron flux and be a general very big bomb.
I think you may wanna lay off the Civ…
