One of the coolest jobs in exploration is be a Principal Investigator. Blue’s Chief Scientist Steve Squyres was the PI for the scientific payloads on Spirit and Opportunity, the intrepid Mars Rovers. Fun conversation on the Ascending Node, out next week! Here's a clip to hold you over.

The future of exploration will be built through thriving spaceports, reusable rockets, orbital assembly, and technologies we once only imagined. Just as railroads and highways transformed our economy, tomorrow’s orbital and lunar economy will help power what comes next. Very exciting times ahead.

40 years ago today, we lost visionary space artist Chesley Bonestell (1888–1986). Long before rockets flew from Cape Canaveral, his stunning paintings of space stations, Moon landings, and Mars missions inspired the engineers and astronauts who made them reality. @ccspacemuseum

One year ago today, we rang the opening bell at the @NYSE, taking Voyager public. In that brief time, we have accomplished so much and led incredible growth across the company. We continue to be mission ready, accelerating the advantage for our customers. Thank you to our team, partners and investors.​ ​ Here's to what comes next.​ ​ $VOYG #MissionReady #AcceleratingtheAdvantage

Congratulations to the Artemis III astronauts - Randy Bresnik, Luca Parmitano, Frank Rubio and Andre Douglas! You're taking the next giant leap in lunar exploration. As we continue to expand our presence in space, we will need a thriving commercial LEO ecosystem for astronaut training, scientific research, and a staging ground for the Moon and Mars. Starlab is proud to be a part of that future.

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.

"We were delighted to welcome industry leaders, government officials, and distinguished guests to our new Earth Base office in Nihonbashi, Tokyo! As interest in lunar exploration continues to expand, the gathering provided an opportunity to exchange perspectives on the opportunities ahead for the space industry and discuss the next steps toward sustainable lunar development. We were especially pleased to host our esteemed Lunar Advisory Board members, Mr. Jean-Jacques Dordain, Mr. Yoshinori Komiya, Dr. Tom Ochinero, and Dr. Alan Stern, whose insights continue to help guide ispace's long-term vision. Amongst industry representatives in attendance were Dr. Nicola ""Nicky"" Fox, Associate Administrator for @NASA's Science Mission Directorate, and Dr. Hiroshi Yamakawa, President of the @JAXA_en Japan Aerospace Exploration Agency. Dr. Fox also added her signature to our Mission Control signature wall, joining the many partners, customers, and supporters who have been part of our journey to the Moon. Thank you to everyone who attended! Through open dialogue and collaboration across industry, academia, and government, we move closer to unlocking the opportunities of the Moon."

Artemis II put humans near the Moon for the first time in 50 years. Unlike Apollo, this time @NASA isn't going alone.​ ​ The signal to industry is clear: build the infrastructure for a permanent lunar presence.​ ​ With the announcement of our intent to acquire @Astrobotic Technology, Voyager will have capability at every infrastructure layer needed to put Americans on the lunar surface and keep them there.​ ​ Read more: ow.ly/xSTx50Z7oRu$VOYG #MissionReady #AcceleratingtheAdvantage
