@NASA @grok use of this instrument?

Jackie Damkjaer Hansen1 year ago

This is really cool! Using the Moon’s reflected sunlight to calibrate Earth sensors sounds like a smart way to get more accurate data from space. Excited to see what Arcstone reveals! 🚀

Samuel Gibson1 year ago

Very cool. Using the Moon as a calibration source is such a smart move

@NASA NASA needs a thorough DOGEing so the President and Congress can trust they're making wise investments in science and not blowing billions in pork barrel projects like SLS.

Why is every single one of your videos a CGI representation of what it actually is? Can you ever show the real thing you know.

Chandrayaan-3, India’s third lunar exploration mission takes off from Sriharikota,Andhra Pradesh. 🚀LVM3 Launch Vehicle Mk III takes the Chandrayaan-3 spacecraft to Geo Transfer Orbit (GTO). 🌝#Chandrayaan3 consists of an indigenous propulsion module, lander module, and a rover with an objective of developing and demonstrating new technologies required for inter-planetary missions. The propulsion module will carry the lander and rover from injection orbit to till 100 km lunar orbit. It also carries a Spectro-polarimetry of Habitable Planetary Earth (SHAPE) payload to study the spectral and polarimetric measurements of earth from the lunar orbit. ISRO is bringing the Moon closer to us !

Introducing Artemis III. Four astronauts. Three launches. Two dockings. One splashdown. In 2027, the Artemis III mission will practice docking the Orion spacecraft with two lunar landers in low Earth orbit — the capability we need to return humanity to the Moon’s surface.

🇺🇸Artemis II launched yesterday, sending four astronauts on the first crewed mission to the Moon in more than 50 years. The crew has already spent a full day in space and completed early milestones, including manually piloting the Orion spacecraft. Today they will perform the critical trans-lunar injection burn that will send them on their path toward the Moon. The roughly 10 day journey includes a close flyby of the lunar surface before using the Moon’s gravity to slingshot them back to Earth for a splashdown in the Pacific Ocean. Source: NASA

Mission VA267: Best of the launch campaign On February 12th, 2026, Arianespace, with Ariane 6, successfully launched 32 Amazon Leo satellites into Low Earth Orbit. From the arrival of the satellites in French Guiana to liftoff from Europe’s Spaceport, mission VA267 was the result of months of preparation and coordination. This recap video takes you through the full journey: - Arrival of the 32 Amazon Leo satellites in French Guiana - Preparation of the Amazon Leo satellites in Kourou - Integration, encapsulation and launch operations - Liftoff of Ariane 6 carrying 32 Amazon Leo satellites into Low Earth Orbit - Successful separations in orbit ✨ Mission VA267 marked the first Arianespace launch supporting the deployment of Amazon’s Low Earth Orbit constellation, whose mission is to deliver fast, reliable internet to customers beyond the reach of existing networks. This mission also initiated the first of 18 Ariane 6 launches contracted by Amazon Leo, laying the foundations for a long-term partnership supporting the rollout of a global connectivity infrastructure. 👉 Watch the full mission highlights below ⬇️ #LaunchingAmbitions ArianeGroup European Space Agency CNES Centre spatial guyanais

For the first time since 1972, astronauts are on their way to the moon. NASA's Artemis 2 mission successfully launched last night and will go on a 10 day mission, though they won't land on the moon this time, instead looping around it and then back to Earth. This mission is part of NASA's preparations for deep-space missions - with landings on the surface and even a lunar base being planned in the coming years. David Harper reports.
