Status set to: Interplanetary Cruise 😎 Our twin spacecraft for @NASA and @ucbssl's ESCAPADE mission have completed their engine burns and are now cruising near Earth–Sun L2 Lagrange point. Blue and Gold will hang tight here until November when they’ll begin their cruise to Mars orbit to begin their science mission studying the Martian magnetosphere. 🎥 Watch what’s ahead

🌕 @gru_space is building durable space habitats so humans can one day live on the Moon and Mars. Its first missions will mine lunar regolith to construct a long-term pressurized habitat on the Moon for commercial space tourism — a hotel on the Moon. Congrats on the launch @skyler_chan_! ycombinator.com/launches/P9g-g…

Commissioning of @NASA's twin ESCAPADE spacecraft, currently operated by @UCBerkeley and @RocketLab, is proceeding smoothly. ESCAPADE snapped this selfie in visible and infrared light. 👇 ssl.berkeley.edu/escapade-sends…


Blue and Gold, the satellites we built for @NASA and @ucbssl, are now more than a million kilometers from Earth 🛰️🛰️ Follow their journey to Mars on @NASA Eyes. eyes.nasa.gov/apps/solar-sys…

In March 1982, humanity received its last direct visual postcard from the surface of Venus. It wasn’t a scenic view or a testament to life but a haunting, alien panorama of a world unlike any other, a true inferno captured by indomitable Soviet Venera 13 spacecraft... On March 1, 1982, Soviet Venera 13 probe survived a descent into one of the most hostile environments in solar system and accomplished something no other mission has since been able to repeat. After punching through Venus’s dense, toxic cloud layers, it touched down on the planet’s blistering surface and operated for 127 astonishing minutes. This remarkable image, a segment of the historic panoramic view, shows a landscape that appears both desolate and strangely familiar, yet utterly hostile. The foreground reveals a part of the Venera lander itself. Beyond it stretches a cracked, dark terrain, a volcanic vista of rough, reddish-brown rock, and compacted sediment. Above, a thick, perpetually yellow sky looms, a murky filter caused by an atmosphere dense with carbon dioxide and sulfuric acid. It’s a view that instantly conveys the suffocating pressure and searing heat of Earth’s “sister” planet. Venus, often shrouded in its thick, reflective clouds, is a world of superlatives in planetary hostility. With surface temperatures soaring over 465°C (869°F)—hot enough to melt lead and an atmospheric pressure 92 times stronger than Earth’s, landing there is akin to dropping a submarine into a superheated oven. Yet, the Soviet Union’s Venera program achieved this impossible feat multiple times. Venera 13, in particular, was an engineering marvel. During that brief window, Venera 13 transmitted the clearest and most detailed images humanity has ever seen from the ground of Venus. Its cameras revealed fractured slabs of basalt, a flat and desolate plain, and a thick, yellow-tinted sky shaped by sulfuric haze. On March 1, 1982, it punched through the crushing atmosphere, deployed its shock-absorbing landing gear, and settled onto the scorching surface. For an astonishing 127 minutes—more than two hours in an environment designed to obliterate electronics in mere minutes, it meticulously worked. It deployed a drill to analyze soil samples, took sound recordings of what would have been a profoundly silent, wind-swept world, and, most famously, transmitted a series of incredible color images back to Earth. These images, alongside those from its twin, Venera 14, remain our clearest, most direct window into this hellish realm. The thick, toxic clouds of sulfuric acid that perpetually cloak Venus hide a runaway greenhouse effect gone wild. This perpetual shroud not only makes direct observation difficult but also traps heat with unimaginable efficiency, creating the hottest planetary surface in our solar system, surpassing even Mercury, which is far closer to the sun. The extreme conditions explain why, since 1982, no lander has successfully sent back images from Venus’s surface. Engineering challenges are simply staggering, demanding materials and technologies that can withstand a combination of heat and pressure almost beyond comprehension. More than forty years later, these photographs remain the only true, firsthand views ever captured from the surface of Venus, a world so extreme that even our best modern technology has yet to return. Venera 13 didn’t just take pictures, it also became the first probe to record sound on another planet. Its microphone captured the eerie, low-frequency vibrations of Venusian winds, a haunting reminder of a world we still know mostly through imagination. #archaeohistories

🛰️🛰️ The twins are talking! We have successfully established contact with both ESCAPADE spacecraft, 💙 Blue and 💛 Gold. We're on our way to Mars to enable @NASA and @ucbssl to study the Martian magnetosphere!



Mars, we're coming for you! 🔴 🛰️ 🛰️ Soon, our twin Explorer spacecraft built for @NASA & @ucbssl ESCAPADE mission will begin their journey to the Red Planet to study the history of its climate. The mission will study how the solar wind interacts with Mars’ magnetic environment and how this interaction drives the planet’s atmospheric escape, revealing how Mars changed from warm and wet to the cold, dry world we see today. By flying two spacecraft in different orbits around Mars, ESCAPADE will get a dual viewpoint to solve the mystery of Mars' atmospheric escape. It’s a low-cost mission delivering high-impact science.

We're all buttoned up and ready for our voyage. Mars or Bust!!

An update on NG-2: ESCAPADE is at Astrotech and GS1 is headed to LC-36 in early October. Next up is the vehicle hotfire mid-month with launch soon thereafter.
