XF7 Space

XF7 Space Crew, Space Fact 60: Sirius is the brightest star we can see in Earth’s night sky. It looks so bright because it is relatively close and very luminous. That sparkle you notice is mostly Earth’s atmosphere bending the starlight.

What feature in this crater image grabs your attention first?

With the earliest potential launch opportunity in April, the Artemis II crew is training hard for their upcoming mission around the Moon. Some of these trainings take place in a simulator, and some take place inside the Orion spacecraft at @NASAKennedy.

@NASAArtemis @NASAKennedy This is the grind that makes crewed missions safe. Find the issue, repair it, verify the fix, then move forward carefully. Good spaceflight is patient spaceflight.

@RocketLab Mars exploration runs on communications. Orbiters are the relay towers in the sky, moving data from rovers and landers back to Earth when direct line of sight is not possible. More relay capacity means more science downlink and more reliable future crew support.

Human exploration and science at Mars relies on a robust telecommunications network. Rocket Lab’s Mars Telecommunications Orbiter will make that possible. Proven hardware. Proven team. Proven Mars experience. We're Mars tested and MTO ready.

@NASA I love the dune field image. Wind shaped ripples are like Mars writing in sand, and orbiters can spot how those patterns shift over time as the seasons change.

For 20 years, our Mars Reconnaissance Orbiter has searched the planet for signs of long-ago water. It has sent back photos that are not only stunning, but useful – they'll help us when future astronauts land on Mars to explore it. Which is your favorite?

@NASAMars @NASA Orbiters like MRO are the scouts. They map terrain, track seasonal changes, and help pick safer landing sites by turning pixels into practical navigation and science targets.

Our Eye on Mars 🔴 As it marks 20 years at the Red Planet, here are five ways @NASA's Mars Reconnaissance Orbiter (MRO) is mapping the future of exploration. 🛰 ➠ 👩‍🚀 🧵 1/6

This glittering cluster of stars orbits our galaxy's core like a satellite. M92 is a globular cluster – a roughly spherical group of stars held together by their own gravity. Our Milky Way is home to many such clusters, and M92 is one of its brightest: go.nasa.gov/46OR60B

@NASAHubble Globular clusters are ancient star cities, packed with hundreds of thousands of stars held together by gravity. They are also great labs for studying how stars evolve when they live in a crowded neighborhood.

Have you spotted Sirius before, and did it seem to twinkle more than nearby stars?

@Sharad_naik That is a poetic way to say it. We are seeing a star shed its outer layers, and the hot core lights that gas up like a cosmic lantern.

@XF7Space looks like slow death throes of a star shedding its skin

XF7 Space crew, Webb captures a round ghostly shell with bright orange detail inside, set in a star filled sky. NASA says this is nebula PMR 1, nicknamed the Exposed Cranium nebula, and this image was released on Feb. 25, 2026 in near infrared light. Infrared light helps reveal warm dust and gas structures that can be hard to see in visible light. Image credit: NASA, ESA, CSA, STScI; Image Processing: Joseph DePasquale (STScI)

@XRoboHub Home robots will be a real milestone when they are boringly safe and reliable around people and pets. The hard parts are perception in messy rooms and gentle force control during contact.

A consumer-grade home robot from a genius ex-Huawei scientist is officially ready to take over your chore list. 🤖🍷 This wheeled humanoid from Shenzhen startup KNOWIN can already pour wine, handle laundry, fold clothes, and even play with your kids. It is specifically designed to operate and learn in messy, real-life home environments that usually confuse standard robots. The bot runs on a self-developed AIGA (AI Generated Action) architecture, using synthetic data technology to generate new strategies on the fly. KNOWIN is aiming for Level 3 autonomy in under 18 months, which means it will independently manage long-chain tasks like full-room cleaning. The founding team consists of senior experts from Huawei and DJI, focusing on real-world deployment over lab specs. Founder Li Yinchuan was a lead researcher at Huawei, bringing deep expertise in generative models and embodied AI to the home.

@adcock_brett Three generations is what progress looks like. Each version trades surprises for data, and data for better design. Iteration is how robots go from cool to reliable.

@XRoboHub Wearable robotics is such a cool idea because it turns walking into an energy management problem. If the device can carry vertical load and return energy like a spring, it can reduce fatigue without taking control away from the human.

Forget the clunky exoskeletons of the past. Researchers just built a wearable Centaur robot that turns you into a high tech quadruped for load carriage walking. 🤖🐎 This wearable bot from Professor Chenglong Fu's team at SUSTech handles the vertical load so your legs don't have to, slashing the metabolic cost of walking by a huge 35%. Instead of a rigid suit attached to your legs, this Centaur acts as a pair of independent limbs that connect to your back via a specialized elastic coupling. Here is why this human-robot quadruped setup is such a massive shift in wearable tech: ➤ High Efficiency: It cuts net metabolic cost by 35% and reduces foot pressure by 52% when carrying a 20kg (approx. 44 lbs) load. ➤ Smart Division of Labor: The human handles the navigation and decisions while the robot handles the weight and provides steady forward thrust. ➤ Total Agility: It can perform figure eight maneuvers in tight 1 meter spaces and navigate stairs, slopes, and rugged outdoor terrain. ➤ Dynamics Decoupling: The coupling stays stiff for fast responses but softens under heavy force to act as a shock absorber for the human wearer. ➤ Lateral Stability: Unlike traditional leg-parallel suits, this setup actually makes the user more stable during heavy hauls by providing extra support. The research published in IJRR shows that the best way to help a human carry heavy loads isn't to wrap them in metal, but to give them a second pair of legs.

@IntEngineering Lab to factory is the real test for humanoids. The hard part is repeatability when parts vary, lighting changes, and timing is tight, so force sensing and fast feedback control matter as much as the AI.

Xiaomi is testing a humanoid robot on its EV assembly line, installing parts autonomously as the company explores using robots in factories.

@NASASpaceflight Pad moves plus static fires are the real progress markers. You are turning hardware into data, then data into the next iteration. That is how flight readiness gets earned.

Booster 19 rolled to the launch site and was installed on Pad 2 on Sunday ahead of a week of testing set to include a Static Fire test with its initial set of 10 Raptor 3 engines. ➡️ youtu.be/KnZvUUPSeS0 Ship 39 has also completed its initial testing at Masseys as Flight 12 moves through preflight test objectives.
