Here is one of our experimental 3D printed Hadfield liquid rocket engines going through some thrust vector control (TVC) profiles! As we scale to our first light-lift orbital launch vehicle, Tundra, and then our medium-lift reusable launch vehicle, Titan, precise control of the rocket at every phase of flight is critical to mission success. Guiding a rocket to orbit, and eventually back to Earth, demands close coordination across every sub-team. Some of the key challenges we’re tackling: ➡️ Reliable & repeatable TVC actuation: ensuring the engine gimbal responds consistently across every test and flight ➡️ High-frequency control loops: real-time systems that keep the vehicle stable from liftoff to orbital insertion ➡️ Propellant sloshing: accounting for the movement of fluids in tanks and its effect on vehicle dynamics ➡️ Wind shear compensation: countering atmospheric disturbances during ascent ➡️ Structural bending & flex modes: managing how the vehicle’s primary structure responds to aerodynamic and thrust loads ➡️ Precision payload delivery: hitting the exact target orbit, every time Our team at NordSpace has been advancing our propulsion systems on many fronts, as we work to unveil our orbital-scale, pump-fed Hadfield and Garneau rocket engines in the near future — the engines that will carry Canada to orbit for the first time, and unlock sovereign access to space. Check out some of our rocket hardware, meet our engineers, join over 400 attendees and over 40 speakers at the Canadian Space Launch Conference, taking place this May 5th in Ottawa.

🚨 URGENT WATER APPEAL — WATER IS LIFE IN GAZA 🚨 💧 Donate now: 👈 Look at the children’s faces when the first drop of water finally reaches them. In Gaza today, water is no longer a simple need. It has become a daily fight for survival. Children walk for hours between destroyed streets carrying empty containers, hoping to return with just one cup of water. Mothers divide every drop carefully, trying to keep their children alive for another day. 👶 Babies cry until their voices fade because nothing is left to ease their thirst. Small exhausted bodies grow weaker. Some children simply collapse in silence. 💧 There is no water to drink. 💧 No water to clean wounds. 💧 No water to protect fragile lives. 💔 Thirst in Gaza does not only cause suffering… thirst kills slowly and silently. And every day it steals more childhood from Gaza’s children. 🚨 Emergency Water Distribution Underway Mohammed’s Team is now delivering clean drinking water directly to displaced families and children living in tents. Water trucks are reaching the camps where people have nothing left to wait for. ⏳ Every minute of delay puts lives at risk. 💧 Every donation becomes water. Every contribution immediately turns into liters of clean water in a child’s hands. Sometimes one single cup of water is the difference between life and death. 🙏 Special thanks to our friends and supporters ❤️ William Menaker (Will 🦥 Menaker) 🩵 Eyup Lovely (Eyup Lovely) 💙 Felix (GoliathFan1952) 🩵 Thomas (@iwasnevrhere_ ) Your voices amplify this mission and help bring real relief to families across Gaza. Every time you share, lives are reached. 💧 Donate now — do not delay life 👉 Be the reason a child drinks water today.

🚨 Donate to the children of Gaza 🚨 To contribute: Before you scroll… Imagine your child waking up in the middle of the night. Not crying because of a nightmare. Not because they’re sick. But because they’re so thirsty they cannot sleep. You reach for a glass of water. There isn’t a single drop. You search the house again. Empty. Then morning comes. The sun rises over the tents. Within hours, the heat inside them becomes unbearable. Children lie awake drenched in sweat. Their lips crack. Their mouths go dry. Some stop asking for water because they already know the answer. For thousands of parents in Gaza… This is not a nightmare. This is how they live. Every single day. Today, our team at Project Mohammed is delivering clean drinking water to families sheltering in displacement camps across Gaza. We reach camps that almost no one else reaches. Every day we receive desperate messages from mothers saying the same words: “Please… my children have no water.” Not food. Not money. Just clean water so their children can survive another day under the relentless summer heat. But our donations have collapsed. If they continue to fall… Our water trucks will stop. And when the trucks stop… The heat doesn’t stop. The thirst doesn’t stop. The suffering doesn’t stop. Only the water does. 💧 One donation today can become the water a child drinks tonight. 🤍 Deep thanks to those who continue standing with Gaza: Eyup (Eyup Lovely) ❤️ Felix (GoliathFan1952) ❤️ William Menaker (Will 🦥 Menaker) ❤️ Your voices are helping children survive while much of the world looks away. Please don’t keep scrolling. For you… This post disappears in a second. For a child trapped inside a sweltering tent… Your decision today could mean the difference between drinking clean water… Or spending another day under crushing heat with nothing to drink. If you cannot donate… Please share. Because one share may reach the person who keeps our water trucks moving. 🙏 Donate Water. Save Lives. Before another child is left to face the heat without a single drop of clean water. To contribute:

#WATCH | Nepal: On several pilgrims and volunteers of Isha Foundation's Sacred Walks (Kailash Mansarovar Yatra) missing or stranded in Nepal amid the flood situation, Maa Gambhiri, Coordinator at Isha Sacred Walks, says, "This was a very unexpected situation that happened because the group was just returning to Kathmandu and they were at the China Immigration Center. When we last spoke to them at 9:05 am, the group leader, Praveen, told us that they had just reached the immigration center and that they were going to start the immigration process. Within 10 minutes, when we tried to contact them again, they were not reachable. This entire tragedy happened within those 10 minutes. We lost touch with the entire group because the entire communication system was down... we've been waiting for an update. On the Nepal side, all the communication systems were down. I think they tried sending some helicopters to get some information. The town on the Nepal side, where 3 of our volunteers were stationed, was completely washed away. A total of 80 people were affected by this. We are still hoping that we will have some information soon from the Chinese authorities, hopefully by tomorrow morning. We are hoping against hope that we will get to hear some good news on this." Speaking about 77 pilgrims that left stranded amid the flood situation in Nepal, she says, "They were from the US, Canada, Australia, Singapore, various countries in Europe, and the UK. We also had people from some of the Asian countries. We had participants from 19 countries. A lot of them were of Indian origin... We have contacted all 19 embassies in India and Nepal. We are in touch with them. They are also looking at how to support us and get some information. But because the tragedy happened in a very remote area and on a very massive scale, I think information is very slow to come by..."

🚨 children in gaza are thirsty, and they cannot wait any longer. 🚨 To contribute :👉 today in gaza, children are not asking for toys. they are not asking for new clothes. they are not asking for anything extraordinary. they are asking for water. at project mohammed, we have delivered more than 250,000 liters of clean water to displaced families across gaza. but 250,000 liters is not enough. every day, more children wake up thirsty. more families search for clean water. more mothers go without drinking so their children can have enough. 💔 children walk long distances carrying empty containers. 💔 families wait for hours under the heat for a single supply of water. 💔 some children are too exhausted to even complain anymore. and when the water finally arrives, you can see it on their faces. relief. because for these children, water is not a convenience. water is survival. imagine being a child and having to thank a stranger on the other side of the world simply because they helped you drink today. this should never be normal. we are still working from inside gaza. we are still carrying water through destroyed streets. we are still trying to reach families who have nowhere else to turn. but our resources are running out. 🚨 we urgently need your help to keep the water flowing. please donate. please share. please speak. even a small donation can help put clean water into the hands of a child today. 🤍 deep thanks to: Eyup (Eyup Lovely) Felix (GoliathFan1952) William Menaker (Will 🦥 Menaker) your support has helped us reach children and families who desperately need clean water. 👉 250,000 liters delivered. thousands of children are still waiting. please don’t let them wait alone.
