How NASA’s SPHEREx Mission Will Map the Cosmos
Ғылым және технология
NASA’s upcoming SPHEREx space telescope mission will map the entire sky like no spacecraft before it. To do that, SPHEREx needs specialized hardware. Three concentric cones called photon shields surround the telescope and block light and heat from the Sun and Earth. Without those shields, the telescope’s detectors would be blinded.
SPHEREx also needs to be cold because it detects infrared light. Invisible to human eyes, infrared is emitted by warm objects on Earth and out in the universe. It’s also emitted by the telescope. Keeping it cold reduces the infrared glow, which lets SPHEREx see faint objects that are really far away.
SPHEREx stands for the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer. Managed by NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, SPHEREx is set to launch no later than April 2025.

I'm so on board with nasa doing many more of these videos.
Nice 👍👍👍
"my dog after his last visit to the vet" GOT ME DYING 💀
I appreciate the acting!
Awesome
looks a bit like a piece from Disaster Area's (the loudest band of the galaxy, from Hitchhiker's Guide to the Galaxy) sound system.

Disaster Area, don't talk to me about Disaster Area. The first ten million years were the worst, and the second ten million years, they were the worst too. The third ten million years I didn't enjoy at all. After that I went into a bit of a decline.
Great mission!
Feels like the 3D movie at Disneyland before they shrink everybody down.
Awesome 😎

Random idea but inviting popular science KZreadrs would certainly help the democratization of the latest NASA projects to the masses. And would probably be a step in getting more funding. Love it or hate it but the military invests massive amounts of money in advertising. I think that would be a step in that direction.

Veritasium, Be smarter Everyday, Real engineering and many others would love to visit and would have a palpable excitement to the SphereX project which then be communicated to millions of children and science enthusiasts like myself.

oh. so its like a hybrid of james webb and gaia!

Wow. Is it an update to Gaia, Euclid?

While both SPHEREx and Euclid are survey telescopes, their objectives and capabilities are different. Euclid will map about one third of the sky, while SPHEREx will scan the entire sky. SPHEREx will study universal inflation, galaxy evolution, and water ices in young star systems.

Presumably, Spherex will regularly face towards the Sun, so how will it be kept cool at these times?

The solar arrays face towards the sun, and the telescope points at 90 degrees or more away from the sun, so sunlight does not shine within the cones. It also points away from the earth as it revolves in its orbit, keeping light from the earth off the telescope.

Great question. SPHEREx (the telescope portion) will face away from the Sun and Earth. But its solar panels always face the sun!

@@NASAJPL , Thank you for the reply. Are there any animations showing how this will be achieved? It's quite hard to imagine ... and interesting! If JPL can share an animation about this I'm sure others would be interested too.
-320F, sorry, how cold is it football fields?
So it uses cones to see but does it have any rods? Eye see a joke!
Stay cool 😎🧊🧊
Is this not like Euclid telescope?

@@NASAJPL Thanks for clearing that up. I thought that space agency may be repeating each other work! I have heard of redundancy however with these kinds of investments it would seem………👍🏾👍👍🏻
Has to be the first JPL video ive watched that actually fails to educate.
There is nothing wrong with humor, more is needed on this planet Thanks NASA. and JPL.
Creating stellarchrotography. Hopefully
This looks so silly, and I love it. ❤

What if everything you map in the far distance is so far away that their light takes a long time to reach us and they don't exist anymore?🤔😮are you mapping fossils of what once was? Still it's not a waste of time if you learn to warp space time you can travel there by going backwards in time? blimey!!😁👍🤔😮
To JPL’s normally stellar media team, I would say with love that this video misses the mark. It’s like you are ashamed that your mission is too boring to interest the public without dumbing it down and adding silly jokes. Take a look at channels like Astrum, Mars Guy, GeoGirl, Fraser Cane, Katie Mack, Cool Worlds, Dr. Becky, Everyday Astronaut, Primal Space for examples of KZreadrs who go deep into technical topics while still being engaging and fun - and cultivating an educated and enthusiastic audience in the process. Let your project leads do what they do best - talk about the mission and what excites them - without giving them a silly script to follow, and you *will* get your viewers interested, because your missions and your people are world class.

This is like the videos they have for the sample of the Martian rocks, but then if you go to their website you can always find much more info.
Is this made for children?
