During our 86th parabolic flight campaign, researchers fired a laser at ultralight graphene aerogels in zero gravity.
They shot forward. Instantly. In 30 milliseconds.
On Earth? Barely a flicker. In microgravity? A completely different story.
No fuel. No moving parts. Just light, steering satellites and powering missions of the future.
*The videos of the experiment have been slowed down 10 times.*

Our astronaut Sophie Adenot shared this video on her social media channels with the caption:
[EN] Day 173 orbit 2680 â Fire is one of the biggest risks we face aboard the International Space Station, so as you can imagine, smoke detector maintenance is performed regularly to keep the crew safe.
In this (accelerated) video, I was servicing the Columbus smoke detector, making sure it remains in perfect condition. At home, remember to check your smoke alarm batteries regularly. In an emergency, on Earth just as much as in space, an early warning can save lives and protect property!
[FR] Jour 173, orbite 2680 â Le feu est lâun des plus grands risques Ă bord de la Station spatiale internationale. Comme vous pouvez lâimaginer, nous effectuons rĂ©guliĂšrement, pour notre propre sĂ©curitĂ©, la maintenance des dĂ©tecteurs de fumĂ©e.
Dans cette vidĂ©o (accĂ©lĂ©rĂ©e!) jâĂ©tais en train dâeffectuer la maintenance du dĂ©tecteur de fumĂ©e du module Columbus, pour quâil reste en parfait Ă©tat de fonctionnement. Chez vous, pensez Ă vĂ©rifier rĂ©guliĂšrement les piles de vos dĂ©tecteurs de fumĂ©e. En cas dâurgence, sur Terre comme dans lâespace, ĂȘtre alertĂ© de façon prĂ©coce peut sauver des vies et protĂ©ger les biens !

Our astronaut Sophie Adenot shared this video on her social media channels with the caption:
[EN] Day 182, orbit 2822 â Living and working in 3 dimensions is amazing⊠Your brain adapts surprisingly quickly, and before long, it feels perfectly normal to see people floating in from every direction, in any orientation! In this video, we were each in our crew quarters, on four different walls!
Chris is now back on Earth, with his feet firmly planted on the ground, and probably missing microgravity đ
[FR] Jour 182, orbite 2822 â Quelle expĂ©rience incroyable que de vivre et travailler en trois dimensions ! Le cerveau sâadapte Ă©tonnamment vite, et sans mĂȘme sâen rendre compte, il devient parfaitement normal de voir des collĂšgues arriver de toutes les directions, dans nâimporte quelle orientation. Dans cette vidĂ©o, nous Ă©tions chacun dans notre propre cabine de couchage, installĂ©e chacune sur un mur diffĂ©rent !
Chris est maintenant de retour sur Terre, les pieds fermement posĂ©s sur le plancher des vaches, et jâimagine que la micropesanteur lui manque đ
