Glad to continue to support such an impactful company! Excited for the years ahead.
We’ve closed a $350M Series E led by @EclipseVC with participation from @NVIDIA’s NVentures. The oversubscribed round fuels growth across our two core business lines: Critical Materials Energy Storage. We’re building a resilient U.S. energy future.

Moving on up to higher orbits!
We’ve raised a $300M Series C to #MobilizeSpace. 🚀 It’s one of the largest venture rounds in space industry history—and it means we’re growing our team and scaling production to keep accelerating in-space mobility. Since our founding in 2021, we’ve flown two successful Mira missions, signed over 30 commercial and government contracts, and maintained our timeline to deliver Helios in 2026. We’re building the infrastructure to move anything, anywhere in space. And we’re just getting started. Learn more: impulsespace.com/updates/imp… #ImpulseSpace

Mira is a go for launch! 🚀    In preparation for LEO Express-2, we’ve completed all pre-launch checks and integrated with @SpaceX’s Falcon 9 at Vandenberg Space Force Base.

Proud to support Impulse and their efforts to accelerate an exciting future in space! Can't wait to watch the progress over the next few years.
We’re excited to announce the close of our $150M Series B funding round, led by Founders Fund, bringing our total raised to $225M. This investment will drive continued development of our Helios and Mira vehicles. 🌌 (1/5)

The world's most advanced high-speed Wi-Fi is coming to United with @Starlink. For free. You’ll be able to stream, game, shop and more on seatback screens and personal devices simultaneously. Expect the same internet you get on the ground… at 35,000 feet. We expect to have Starlink on all 1,000 United planes over the next several years. Learn more: uafly.co/3B3CDRv

They were at 250k 2 months ago. And over 400k today. Where will they be at year end? How about at end of 2023? Could the Terminal bottleneck be resolved?😉 🚀
