BlueBird 11-13 launches Wednesday: the story behind this week's busiest lunar day

2026-08-04 · by Priya Raman · News Editor · Curatorial · Newsletter

Three milestones, one through-line. This week's spaceflight news is being driven by a collision between accelerating commercial ambition and infrastructure that hasn't kept pace with it. The direct-to-cell market moving toward commercial service, the ISS crew gap that NASA's about to close, and the Moon becoming an accidental disposal site — these aren't separate stories. They're the same story told three different ways: the space economy is scaling faster than its operating norms.

BlueBird 11-13 lifts off Wednesday — three more Block 2 birds push AST toward commercial service

SpaceX is targeting 3:42 AM Eastern time Wednesday, August 5 (7:42 AM UTC) for the BlueBird 11-13 mission, launching from Space Launch Complex 40 at Cape Canaveral. Additional opportunities are available within the window through 5:18 AM Eastern if needed. The vehicle will deploy three Block 2 satellites for AST SpaceMobile, each carrying a 2,400-square-foot phased-array antenna — the largest commercial communications antenna array ever placed in low Earth orbit.

Once BlueBird 11-13's three birds join the four Block 2 satellites already on orbit from earlier missions, AST SpaceMobile's constellation will reach seven total Block 2 satellites. That number — seven — is the threshold the company has cited internally as the minimum for continuous cellular broadband coverage across the United States, parts of Europe, and Japan using standard unmodified phones. It's the difference between intermittent and genuinely continuous service, and it's why Wednesday's launch is the most operationally significant of the week.

The service model is carrier partnerships, not a standalone subscription. AT&T, Verizon, and Japan's Rakuten are signed on to integrate space-based cellular into existing plans — no new hardware, no specialized app required on the phone side. AST SpaceMobile's CEO confirmed in a July briefing that direct-to-cell testing is already underway with carrier partners, with commercial service targeted before the end of the year in initial markets.

AST's constellation strategy is built in blocks. Block 1 was the proof-of-concept with BlueBird 1-5. Block 2, of which BlueBird 11-13 is the second launch, is the initial operational block. The full planned constellation is 168 satellites — global coverage, all carriers, full mobile broadband. But the real inflection point is seven birds on orbit, and that's what Wednesday gets us to.

The ISS has been running on reduced crew for months — Crew-13 in September is the fix

NASA held its Crew-13 mission overview briefing on Monday, August 3, confirming the four-person crew and mid-September launch target from Kennedy Space Center. The crew: Commander Jessica Watkins (NASA, veteran of Crew-4), Pilot Luke Delaney (NASA, first flight), Mission Specialist Joshua Kutryk (CSA, first flight), and Mission Specialist Sergey Teteryatnikov (Roscosmos, first flight). The spacecraft is a SpaceX Crew Dragon; the rocket is a Falcon 9.

Crew-13 is the 13th operational NASA Commercial Crew rotation and the 21st crewed orbital flight of a Crew Dragon. The four-person crew will spend approximately six months aboard the ISS before returning to Earth, completing a standard long-duration expedition.

What's notable isn't the mission itself — crew rotations are now as routine as satellite launches. What's notable is the gap. The ISS has been running on reduced crew since the previous rotation departed earlier this year. NASA's standard crew complement is four astronauts for balanced operations across life support, science, and station maintenance. The station has been operating with fewer for several months — an extended period that makes any crew rotation significant. Crew-13 restores full staffing.

Thursday at 06:35 UTC, a Falcon 9 upper stage strikes the Moon — and the debris problem comes into focus

On Thursday, August 6 at approximately 06:35 UTC (02:35 AM Eastern), a spent Falcon 9 upper stage designated 2025-010D will impact the lunar surface near Einstein Crater, traveling at roughly 2.43 kilometers per second (~8,700 kilometers per hour). The upper stage is approximately 3,900 kilograms (about 4.3 US tons). It is not from a CRS cargo mission — it delivered two commercial lunar rovers in 2024: Blue Ghost-1 (Firefly Aerospace's lander) and Hakuto-R Mission 2 (ispace's lander), both of which landed successfully on the Moon in 2024. After deploying its payload, the upper stage was left in a lunar transfer trajectory it was never designed to return from.

The impact will occur on the sunlit far side of the Moon, near Einstein Crater on the lunar eastern limb as seen from Earth. The debris plume — a central ejecta spike potentially reaching 75–100 kilometers in altitude — is modeled to be potentially observable from ground- and space-based facilities, though the impact itself cannot be watched directly from Earth. The event has been tracked for months by Bill Gray, an independent astronomer and developer of the Project Pluto orbital tracking software, who provided the trajectory data to multiple research teams. Two separate arxiv preprints model the expected impact dynamics and resulting ejecta field.

This is not a rare accident. Accidental lunar impacts from spent upper stages have occurred multiple times in recent years, though this one is among the most massive. The problem is structural: current international space law — the Outer Space Treaty framework — does not mandate specific disposal procedures for upper stages in lunar transfer orbits. Operators choose their own disposal method. As the number of lunar missions grows, so will the number of upper stages left in unstable orbits that ultimately impact the lunar surface.

There is no binding international protocol governing this. The FCC has proposed disposal guidelines for geostationary transfer orbits but has not finalized rules for lunar trajectories. The Blue Ghost-1 and Hakuto-R Mission 2 upper stage is, in this sense, a data point in a larger trend: the Moon is becoming a disposal site for the infrastructure we leave behind. Thursday's impact won't be visible from Earth. But it is the kind of event that becomes routine — and then becomes a policy problem.

This week in launches

The week's launch cadence is dominated by SpaceX. A Falcon 9 Starlink mission from Vandenberg Space Force Base is scheduled for today, Tuesday, August 4 at 10:00 AM Eastern (1400 UTC), carrying 24 Starlink V2 Mini satellites to low Earth orbit — continuing SpaceX's high-frequency Vandenberg cadence. Tomorrow's BlueBird 11-13 launch is the most notable non-Starlink mission of the week. Further out, a Falcon 9 Starlink mission from Cape Canaveral and a JAXA H3 launch from Tanegashima carrying Japan's Quasi-Zenith Satellite 7 are also on the calendar for this week.

For skywatchers, the Perseid meteor shower peaks Thursday night into Friday morning (August 6–7), producing up to 75 meteors per hour under ideal dark-sky conditions. A 10% illuminated waxing crescent Moon sets well before the prime viewing window, leaving the sky dark enough for the fainter streaks. The Perseids are the most reliable annual meteor shower for Northern Hemisphere observers and one of the few that performs well even from suburban skies.
