humans have landed enough spacecraft on the Moon that,

the missions can start to feel… ordinary.

Whatever, we've been doing that since the '60s!

The truth is, though, those landings are hard.

They often depend on thousands of steps going not just mostly right,

Last Friday, India became the latest nation to learn that firsthand

when they lost contact with their spacecraft right before it landed on the Moon.

an orbiter, a rover, and a lander called Vikram.

It launched in July, and its goal was to study the South Pole-Aitken Basin

In 2009, India's first Chandrayaan mission detected ice within some of the basin's

which could someday support a permanent lunar base

or help us understand where Earth's water came from.

So the idea was to land Vikram and its rover

near the area and explore the terrain up-close for the first time.

Years of work went into the mission, and it was supposed to be a big, historic thing

— because it also would have been India's first Moon landing.

As the lander approached the Moon last week,

it appeared to be traveling faster than expected.

Then, only about two kilometers above the lunar surface,

The next day, Chandrayaan-2's orbiting satellite captured an image

of what appeared to be Vikram's landing site, but there was still no signal from it.

that's all that had been confirmed by ISRO,

Reports had started to trickle out that the lander may at least be in one piece,

but in the world of space exploration, they're not uncommon.

After all, none of the countries that have landed on the Moon

In fact, the Soviet Union failed eleven times before achieving the first successful landing

And earlier this year, an Israeli lander failed

in almost exactly the same way Vikram may have.

So even if they never get in contact with their lander,

Chandrayaan-2 also won't be a total loss.

The orbiter is doing great, and ISRO expects it will continue to study the Moon

In that time, its instruments will study the thin lunar atmosphere and the Moon's water,

and its camera will snap some really high-resolution photos.

According to ISRO, that camera is actually the highest-resolution one ever sent to orbit

and it's capable of taking pictures of objects just 32 centimeters across.

That will be great for studying features on the surface —

and maybe even helping ISRO diagnose what happened during last week's landing.

Missions are an awesome way to learn about the solar system,

but we don't always need to go to space to learn something about it.

Sometimes, meteors come crashing to Earth,

bringing new information and the chance for new discoveries.

And that's something another team of scientists has been celebrating lately!

a team from Caltech recently published their study of the Wedderburn meteorite,

which was discovered in Australia in 1951.

but the researchers confirmed something special about it:

It contains a new, naturally-occurring mineral!

That find came with a pretty nifty perk, too:

By rule, only minerals known to exist in nature get their own proper names.

So even though scientists have seen this one in smelters for decades,

it's always been called by its chemical formula.

The team chose to call this mineral edscot tite,

Who first proposed the mineral exist in the Wedderburn meteorite.

At the time, though, instruments weren't advanced enough for Scott to confirm the mineral

so that's where this new research came in.

The team from Caltech examined their sample using methods like scanning electron microscopy,

which uses a beam of electrons, rather than light

Those images revealed tiny pieces of edscottite squished between other minerals.

And the images were detailed enough for the team to study the mineral's structure

and finally confirm Scott's hypothesis from decades earlier.

Well, it may have been surprisingly similar to how it's made in smelters on Earth.

which means it was most likely part of the core of a large asteroid or small planet.

This object likely formed early in the solar system when a bunch of smaller rocks got crunched

All those collisions would have added a lot of heat to the object,

which would have helped its molten metal sink towards the center to form a core.

“Hot metal” also sounds a lot like the conditions inside a smelter,

A piece of an asteroid or planet that hasn't existed for millions or billions of years
