Hey. Why isn’t the moon landing a national holiday in the US. Isn’t that fucked up? Does anyone else think that’s absurd?

Going for a walk. Apollo 17 astronaut Ronald Evans leaves to the spacecraft to retrieve film cassettes from the Service Module, Dec 1972. Mr. Evans was Command Module Pilot & orbited the moon a record 75 times during the mission. He holds the record for most time spent in lunar orbit at just shy of 148 hours. He is the last human to orbit the moon solo. A historic figure in space pioneering.

SPACEMAS DAY 2 ✨🪐🌎☄️☀️🌕

There's a new space telescope in the sky: Euclid. Equipped with two large panoramic cameras, Euclid captures light from the visible all the way to the near-infrared. It took five hours of observing for Euclid's 1.2-meter diameter primary mirror to capture, the 1000+ galaxies in the Perseus cluster which lies 250 million light years away. More than 100,000 galaxies are visible in the background, some as far away as 10 billion light years. Euclid's initial surveys, covering a third of the sky and recording over 2 billion galaxies, will enable a study of how dark matter and dark energy have shaped our universe.

Setting Sail to Travel Through Space: 5 Things to Know about our New Mission

Our Advanced Composite Solar Sail System will launch aboard Rocket Lab’s Electron rocket from the company’s Launch Complex 1 in Māhia, New Zealand no earlier than April 23, at 6 p.m. EDT. This mission will demonstrate the use of innovative materials and structures to deploy a next-generation solar sail from a CubeSat in low Earth orbit.

Here are five things to know about this upcoming mission:

1. Sailing on Sunshine

Solar sails use the pressure of sunlight for propulsion much like sailboats harness the wind, eliminating the need for rocket fuel after the spacecraft has launched. If all goes according to plan, this technology demonstration will help us test how the solar sail shape and design work in different orbits.

2. Small Package, Big Impact

The Advanced Composite Solar Sail System spacecraft is a CubeSat the size of a microwave, but when the package inside is fully unfurled, it will measure about 860 square feet (80 square meters) which is about the size of six parking spots. Once fully deployed, it will be the biggest, functional solar sail system – capable of controlled propulsion maneuvers – to be tested in space.

3. Second NASA Solar Sail in Space

If successful, the Advanced Composite Solar Sail System will be  the second NASA solar sail to deploy in space, and not only will it be much larger, but this system will also test navigation capabilities to change the spacecraft’s orbit. This will help us gather data for future missions with even larger sails.

4. BOOM: Stronger, Lighter Booms

Just like a sailboat mast supports its cloth sails, a solar sail has support beams called booms that provide structure. The Advanced Composite Solar Sail System mission’s primary objective is to deploy a new type of boom. These booms are made from flexible polymer and carbon fiber materials that are stiffer and 75% lighter than previous boom designs. They can also be flattened and rolled like a tape measure. Two booms spanning the diagonal of the square (23 feet or about 7 meters in length) could be rolled up and fit into the palm of your hand!

5. It’s a bird...it’s a plane...it’s our solar sail!

About one to two months after launch, the Advanced Composite Solar Sail System spacecraft will deploy its booms and unfurl its solar sail. Because of its large size and reflective material, the spacecraft may be visible from Earth with the naked eye if the lighting conditions and orientation are just right!

Y'all, the world is sleeping on what NASA just pulled off with Voyager 1

The probe has been sending gibberish science data back to Earth, and scientists feared it was just the probe finally dying. You know, after working for 50 GODDAMN YEARS and LEAVING THE GODDAMN SOLAR SYSTEM and STILL CHURNING OUT GODDAMN DATA.

So they analyzed the gibberish and realized that in it was a total readout of EVERYTHING ON THE PROBE. Data, the programming, hardware specs and status, everything. They realized that one of the chips was malfunctioning.

So what do you do when your probe is 22 Billion km away and needs a fix? Why, you just REPROGRAM THAT ENTIRE GODDAMN THING. Told it to avoid the bad chip, store the data elsewhere.

Sent the new code on April 18th. Got a response on April 20th - yeah, it's so far away that it took that long just to transmit.

And the probe is working again.

From a programmer's perspective, that may be the most fucking impressive thing I have ever heard.
