Welcome back to Telemetry
A busy cycle in orbit and beyond. Let's get into it.
Shenzhou-21 Crew Returns Home Aboard a Different Spacecraft After Debris Incident
China's Shenzhou-21 crew landed at the Dongfeng site in Inner Mongolia on May 29 after 210 days on Tiangong, but rode home in the Shenzhou-22 capsule rather than their own. The swap was forced by a cracked viewport window discovered on the Shenzhou-20 spacecraft in November 2025, which displaced that crew into SZ-21's vehicle and left SZ-21's crew without a safe return option. China's emergency backup program had an uncrewed SZ-22 on the pad and launched it within 20 days of the damage discovery. During the gap, commander Zhang Lu and flight engineer Wu Fei conducted three spacewalks, including an inspection of the damaged window; Zhang now holds the Chinese record with seven total EVAs. The freshly launched Shenzhou-23 crew is now aboard Tiangong, and their spacecraft includes enhanced viewport protection.

Webb directly measures a black hole that outweighs its own galaxy
For the first time, researchers have directly measured the mass of a black hole in the early universe, finding that the object at the center of Abell2744-QSO1 contains roughly 50 million solar masses and accounts for at least two-thirds of the entire system's mass. That ratio is thousands of times larger than in nearby galaxies, where black holes represent only a small fraction of their host's total mass. The measurement was made possible by Webb's NIRSpec instrument, which traced Keplerian gas motion around the black hole: the gas orbits the central mass the way planets orbit the sun, allowing a direct gravitational calculation. The near-total absence of heavy elements in the surrounding gas further confirms that few stars have formed, meaning this black hole predates its own galaxy rather than growing from one.
Missions & Launches
ULA launches seventh Amazon Leo batch on Atlas 5 despite weather delays
Atlas 5 rocket AV-113 lifted off from Cape Canaveral at 7:53 p.m. EDT on May 29, carrying 29 Amazon Leo broadband satellites on the LA-07 mission, the 109th Atlas 5 flight overall. The launch came despite only a 30% favorable weather forecast, with the T-minus four-minute hold extended to clear surface electric field and anvil cloud violations. This was the penultimate Atlas 5 mission Amazon contracted with ULA, with one remaining scheduled for July 2026. The flight takes on added urgency after the May 28 New Glenn explosion damaged Blue Origin's launch pad, leaving Amazon's path to meeting an FCC deadline requiring half its 3,200-satellite constellation operational by end of July 2026 significantly constrained, with only around 300 satellites currently in orbit.

Five Chinese rockets approach debut or recovery attempts this year
China has a dense queue of new rockets approaching first flights and booster recovery tests. CASC's Long March 12B is vertical at Jiuquan with landing legs visible, though whether it will attempt a recovery on its debut remains unclear. Galactic Energy's Pallas-1 is also on the pad, with recovery hardware installed but not expected to be used on flight one. The Long March 10B, a cargo variant tied to China's crewed lunar program, completed a wet dress rehearsal in April and is targeting a ship-based booster catch, possibly in July. Landspace's Zhuque-3 and iSpace's Hyperbola-3 round out the slate, both targeting 2026 flights after recent ground milestones.

Business
NASA Selects Seven Firms for $300M Johnson Space Center Upgrades
NASA has awarded a multiple-contractor construction contract covering up to $300 million in facility work at Johnson Space Center in Houston. The seven awardees, including Coho Construction Management, Conti Federal Services, and HITT Contracting, will compete for individual task orders covering upgrades to utilities, mission-support buildings, and equipment across the campus. The contract is structured as an indefinite-delivery/indefinite-quantity vehicle, meaning specific projects are assigned through competed task orders rather than a single fixed scope. All funds must be obligated by September 30, 2026, suggesting most work is expected to begin quickly to meet that fiscal deadline.

Space Force taps SpaceX for $4.16B airborne target-tracking satellite constellation
SpaceX won a $4.16 billion Space Force contract to build a low-Earth-orbit constellation that can detect and track fighter jets, cruise missiles, and hypersonic weapons from space. The program, called the space-based Air Moving Target Indicator, is meant to complement aircraft like the E-3 AWACS as adversaries develop anti-access systems that threaten airborne surveillance platforms. An initial operational capability is targeted for 2028. The award follows a separate $2.29 billion Space Force contract SpaceX received days earlier for a military mesh communications network, giving the company a central role in both Pentagon sensing and data-relay architectures.

Mineral ring in Martian basin points to ocean lasting over a million years
A band of manganese minerals concentrated at consistent altitudes in Utopia Planitia, Mars's largest northern basin, has given researchers their clearest timeline yet for an ancient ocean there. The minerals accumulate where dissolved manganese in water contacts atmospheric oxygen, tracing ancient shorelines the way a bathtub ring marks a waterline. Spectral data from China's Zhurong rover and ESA and NASA orbiters, analyzed with a custom deep learning model across nearly six million spectra, placed the deposit in the Hesperian epoch, roughly 3.7 to 3.0 billion years ago, with the ocean persisting for 0.8 to 1.5 million years. That duration overlaps with the period on Earth when the earliest life is thought to have emerged.
Global Roundup
ESA's May Highlights: Asteroid Flybys, Mars Landing Tests, and Webb Discoveries
ESA's May 2026 roundup covers an asteroid flyby, Mars landing technology tests, and new findings from the Webb and Hubble space telescopes. Astronaut Sophie Adenot also photographed meteor showers from aboard the International Space Station. The agency's monthly video summary runs just over four minutes and covers the full range of European space activity. ESA also announced a collaboration with game studio DON'T NOD on Aphelion, a sci-fi title built around real space science.
