We are going to the Moon!
At 1:47 a.m. EST on Nov. 16, 2022, our Orion spacecraft launched aboard the Space Launch System (SLS) rocket from historic Launch Complex 39B at NASA’s Kennedy Space Center in Florida on a path to the Moon, officially beginning the Artemis I mission.
This mission is the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, the SLS rocket, and Kennedy ground systems. This is the very first time this rocket and spacecraft have flown together, and it’s the first of many Artemis missions to the Moon. Artemis I is uncrewed, but it lays the groundwork for increasingly complex missions that will land humans on the lunar surface, including the first woman and the first person of color to do so.
With Artemis, we will build a long-term human presence on the Moon and prepare humanity for future exploration plans to Mars and beyond.

Get dazzled by the true spectrum of solar beauty. From fiery reds to cool blues, explore the vibrant hues of the Sun in a mesmerizing color order. The images used to make this gradient come from our Solar Dynamics Observatory. Taken in a variety of wavelengths, they give scientists a wealth of data about the Sun. Don't miss the total solar eclipse crossing North America on April 8, 2024. (It's the last one for 20 years!) Set a reminder to watch with us.

The French president Macron is trying to raise their retirement age from 62 to 64 (and 67 for some?). French people have protested peacefully for 2 months but yesterday his government went ahead and invoked an article in their constitution that allows them to force the bill past the National Assembly without letting its deputies vote on it. Now Paris is burning ☺️
The trash collectors have gone on strike and so 7000+ tons of garbage has been piling up in the streets, then they get set on fire by protestors at night ☺️

If you’re wondering - “Retirement age at just 64 and they’re burning shit down? In my country I can’t retire until 65/67/70+!!”
French people have kept it low BECAUSE they burn shit down if it’s threatened ☺️
i have an undying need to see my fav space trio fighting tgt again 😭
HAPPY SEPTEMBER 21st
forgive me for this crime (finally completed) and please sneak it into your party playlists to confuse people 💖

When our Perseverance Mars rover lands on the Red Planet on Feb. 18, 2021, it will bring along the Ingenuity helicopter.
This small-but-mighty craft is a technology demonstration that will attempt the first powered, controlled flight on another planet. Its fuselage is about the size of a tissue box, and it weighs about 4 pounds (1.8 kg) on Earth. It started out six years ago as an implausible prospect and has now passed its Earthbound tests.
Here are six things to know about Ingenuity as it nears Mars:
This Mars helicopter is known as a technology demonstration, which is a project that aims to test a new capability for the first time with a limited scope. Previous technology demonstrations include Sojourner, the first Mars rover, and the Mars Cube One (MarCO) CubeStats that flew by Mars.
Ingenuity does not carry any science instruments and is not part of Perseverance’s science mission. The only objective for this helicopter is an engineering one – to demonstrate rotorcraft flight in the thin and challenging Martian atmosphere.
Mars’ atmosphere is around 1% the density of Earth’s. Because of that lack of density, Ingenuity has rotor blades that are much larger and spin faster than a helicopter of Ingenuity’s mass here on our planet. It also must be extremely light to travel to Mars.
The Red Planet also has incredibly cold temperatures, with nights reaching minus 130 degrees Fahrenheit (-90 degrees Celsius) in Jezero Crater, where our rover and helicopter will land. Tests on Earth at the predicted temperatures indicate Ingenuity’s parts should work as designed, but the real test will be on Mars.
Ingenuity is nestled sideways under Perseverance’s belly with a cover to protect the helicopter from debris during landing. The power system on the Mars 2020 spacecraft periodically charges Ingenuity’s batteries during the journey to the Red Planet.
In the first few months after landing, Perseverance will find a safe place for Ingenuity. Our rover will shed the landing cover, rotate the helicopter so its legs face the ground and gently drop it on the Martian surface.
NASA’s Jet Propulsion Laboratory will not be able to control the helicopter with a joystick due to delays communicating with spacecraft across interplanetary distances. That means Ingenuity will make some of its own decisions based on parameters set by its engineering team on Earth.
During flight, Ingenuity will analyze sensor data and images of the terrain to ensure it stays on a flight path designed by project engineers.
Ingenuity’s team has a long list of milestones the helicopter must pass before it can take off and land in the Martian atmosphere.
Surviving the journey to and landing on Mars
Safely deploying onto the Martian surface from Perseverance’s belly
Autonomously keeping warm through those intensely cold Martian nights
Autonomously charging itself with its solar panel
Successfully communicating to and from the helicopter via the Mars Helicopter Base Station on Perseverance
The Mars helicopter intends to demonstrate technologies and first-of-its-kind operations needed for flying on Mars. If successful, these technologies and flight experience on another planet could pave the way for other advanced robotic flying vehicles.
Possible uses of a future helicopter on Mars include:
A unique viewpoint not provided by current orbiters, rovers or landers
High-definition images and reconnaissance for robots or humans
Access to terrain that is difficult for rovers to reach
Could even carry light but vital payloads from one site to another
