NASA Studies 30-Day Crewed Venus Airship Mission at 50km Altitude

Summary
NASA’s HAVOC study examined a 30-day mission with a two-person habitat floating about 50 km above Venus, where pressure is near Earth sea level and temperatures run roughly 30-70C.
At that altitude, Venus’s dense carbon-dioxide atmosphere makes breathable air itself a lifting gas, giving a sealed aerostat buoyancy while avoiding the planet’s 467C surface and 93-bar pressure.
The concept remains an internal engineering study, not an approved program, because entry, airship deployment and inflation, and launching a return rocket from the floating craft are unresolved hurdles.
Sulphuric-acid clouds, fast winds that circle Venus in about four Earth days, and the need for closed-loop water, food and waste systems still block any long-term settlement.
NASA’s work suggests Venus has a physically habitable layer, but not a self-sustaining human environment; even a months-long robotic aerostat would be a major step.
