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!

Japan is on track to beam solar power from space to Earth next year, two years after a similar feat was achieved by U.S. engineers. The development marks an important step toward a possible space-based solar power station that could help wean the world off fossil fuels amid the intensifying battle against climate change.
Speaking at the International Conference on Energy from Space, held here this week, Koichi Ijichi, an adviser at the Japanese research institute Japan Space Systems, outlined Japan's road map toward an orbital demonstration of a miniature space-based solar power plant that will wirelessly transmit energy from low Earth orbit to Earth.

Hi there! I love your writing and I was wondering if I could get a request? Just something fluffy between Astarion and a Tav who's body runs HOT. Gets hot super easily and finds it hard to sleep on humid nights. I feel like Astarion would LOOOVE their warmth and could help cool them off when they're too hot.
Hmmm... Do you know what DnD race really runs hot? Fire Genasi!
Those who think of other planes at all consider them remote, distant realms, but planar influence can be felt throughout the world. It sometimes manifests in beings who, through an accident of birth, carry the power of the planes in their blood. The genasi are one such people, the offspring of genies and mortals.
Astarion x Fire Genasi
Your skin is hell hot and you have fire resistance.
You feel warm in winter but humid summer days are torture.
Let's say, Astarion is obsessed with your body heat.
Your blood runs so hot, that it feels boiling.
And your skin feels warm as if it was enchanted with fire magic.
Early in your relationship, Astarion would always find a way to sneak longer around you.
Once he ended dining, he would find every possible reason to stay close.
Until you permitted him to stay.
Now, he wraps himself around you like a weighted blanket and you finally get some pleasant coldness.
As your relationship progresses, you get more and more comfortable with each other.
Sometimes when you feel too hot, you run up to Astarion to wrap yourself around him.
He does the same when he can't stand the coldness of his own body.
There are also some other tricks you know - you can create fire sparkles with your fingers and you do that to calm Astarion down when the darkness takes a grip on him.
When he screams in pain caused by invisible claws, and every touch feels acid, you create flame and let Astarion watch it.
It mesmerizes him and as he watches you start speaking in Ignan, a primordial language of your ancestors, the language full of sharp clicks and hisses.
Astarion slowly relaxes and allows you to touch him. You can sit like that for hours, his cheek placed on your chest, his eyes on the flame as you talk about things he can't understand.
He finally starts meditating, and you tug him closer so he can take all the warmth he needs.
