Cryogenic fix clears Blue Origin's New Glenn for next launch

Blue Origin has been cleared for another New Glenn launch after investigators traced the April 19 anomaly to a cryogenic leak that froze a hydraulic line, causing insufficient thrust on the second stage and placing AST SpaceMobile's BlueBird 7 satellite in an off-nominal, too-low orbit. The FAA grounded the mission pending fixes, the booster Never Tell Me The Odds landed successfully on its first reflight, and Blue Origin says corrective measures are in place as it plans to ramp production to around 60 upper stages by 2028 to boost launch cadence.

US Carriers Team Up for Rural Wireless Expansion Using Shared Spectrum and Satellites

AT&T, T-Mobile, and Verizon announced an agreement in principle to form a joint venture that would pool ground-based spectrum and invest in satellite-based, direct-to-device connectivity to close wireless dead zones, aiming to create a unified standard with satellite operators; the plan is still under negotiation and subject to closing conditions, but could improve coverage in rural and hard-to-reach areas.

SWOT Satellite Reveals Dispersive Tsunami Patterns Across the Pacific

NASA’s SWOT satellite captured the first high-resolution, space-based track of a major Pacific tsunami from the Kuril–Kamchatka earthquake, revealing dispersive wave energy across a wide swath and challenging the traditional view that giant tsunamis travel as a single non-dispersive wave. By combining SWOT data with DART buoy measurements, researchers refined the earthquake’s source and suggested a longer southward rupture, with implications for improving real-time tsunami forecasting.

Blue Origin's New Glenn: booster lands, payload misorbit prompts investigation

Blue Origin's NG-3 mission achieved a successful booster landing, but an upper-stage thrust anomaly prevented the second burn from placing AST SpaceMobile's Bluebird 7 satellite into the planned orbit, leaving the satellite in an off-nominal orbit and ultimately deemed lost. The FAA has grounded New Glenn while Blue Origin investigates the issue, and the incident casts uncertainty over the rocket's 2026 launch cadence. Despite the mishap, the company aims to continue flights and pursue milestones like the Blue Moon lunar landers, with NASA and industry partners expressing cautious optimism about ongoing programs.

Morgan Stanley Sees Amazon’s Globalstar Deal Expanding Its Leo/Space Ambitions

Morgan Stanley’s Brian Nowak argues Amazon’s $11.6B Globalstar acquisition would accelerate its Leo satellite strategy by enabling direct-to-device connectivity, securing coveted L/S-band spectrum, expanding in-orbit capacity, adding Band 53 options for future operations, and leveraging Apple partnerships for real-world D2C use; with a Buy/Overweight stance and a $300 target, the Street is broadly bullish (average ~14% upside) as AMZN stock rose about 4% on the news.

FAA grounds Blue Origin's New Glenn after payload ends up in unintended orbit

The FAA has grounded Blue Origin’s New Glenn after its second stage placed AST SpaceMobile’s BlueBird 7 satellite into a lower-than-planned orbit; the booster landed safely, but the satellite cannot operate and will be de-orbited. Authorities have offered few details, Space Force data is inconclusive about what’s in orbit, and a return-to-flight timeline has not been provided.

AST SpaceMobile hit by misaligned orbit, stock slides as Blue Origin loses satellite

AST SpaceMobile’s stock fell about 9% after Blue Origin’s New Glenn rocket placed the BlueBird 7 satellite in a lower-than-planned orbit and the satellite was later deemed lost. Insurance will cover the loss, and AST still plans monthly launches in 2026 with satellites 8–10 ready to ship. Analysts say the financial impact should be limited, but investor sentiment is now more closely tied to Blue Origin’s trajectory, potentially complicating AST’s goal of 45 satellites by year-end.

SWOT Satellite Reveals Braided Pacific Tsunami and Forecast Implications

The SWOT satellite captured the first high-resolution, spaceborne swath of a Pacific-wide tsunami triggered by the 2025 Kuril–Kamchatka quake, revealing a braided energy pattern and dispersive waves that challenge traditional non-dispersive tsunami models; by combining SWOT data with DART sensors and seismic records, scientists revised the rupture length and underscored the need to merge multiple data streams for more accurate near-real-time tsunami forecasting.

Starlink satellite 34343 appears to break apart after on-orbit anomaly

SpaceX says Starlink satellite 34343 suffered an on-orbit anomaly on March 29 at about 560 km (348 miles) altitude and is no longer in one piece; LeoLabs detected a fragment-creation event. SpaceX will monitor debris and pursue a root-cause fix, with no expected risk to the International Space Station, Artemis II, or Transporter-16.

NASA’s SWOT Satellite Maps the Ocean Floor From Space

NASA and CNES’s SWOT satellite uses gravity-driven sea-surface height data to map the seafloor, enabling detection of smaller features like seamounts and abyssal hills and potentially expanding the catalog from about 44,000 to up to 100,000. The effort aims to map the entire ocean floor by 2030, complementing ship-based sonar with near-global coverage every 21 days.

Galaxy Phones Gain Direct Satellite Access With App Support

Samsung has published a list of satellite-ready apps that can work on Galaxy devices even without cellular coverage, enabled through carrier partnerships in Europe, Japan, and North America. Galaxy S22+ and newer models generally support direct satellite connectivity (with some markets also supporting select Galaxy A series), and service varies by country. Current satellite-ready apps include Find My Mobile, Google Maps, Google Play Services, WhatsApp, Samsung Account, Samsung Health, Weather, and X (Twitter), among others.

NASA's Van Allen Probe A Crashes in Uncontrolled Reentry Over the Pacific

An aging NASA satellite, Van Allen Probe A, reentered Earth’s atmosphere in an uncontrolled event over the Pacific after fuel depletion; most of the 600-kg spacecraft is expected to burn up, with NASA estimating a 1-in-4,200 chance of bodily harm on the ground. Its twin, Van Allen Probe B, remains in orbit and is not expected to reenter before 2030. Launched in 2012 to study the Van Allen radiation belts, the probes ceased operation after fuel ran out in 2019.

Earth’s moving green center points northeast as vegetation responds to climate and CO2

Decades of satellite observations show Earth's vegetation forms a moving balance point across continents and seasons, with the global center of greenery migrating northeast as climate change and higher CO2 reshape growing conditions. The shift is dominated by Northern Hemisphere vegetation, has accelerated since 2010, and is linked to longer growing seasons and land management in reliable water regions, while drought and heat can still slow growth. Researchers suggest tracking this moving center could help explain planetary vegetation patterns and improve climate and land-use models.

Iran's Taftan Volcano Uplifts, Hinting at Wake-Up After 700,000 Years

Satellite data show the Taftan volcano in southeastern Iran rising about 9 cm (3.5 inches) over 10 months, signaling pressure building in a shallow hydrothermal system near the summit rather than a magma-driven eruption. Researchers say the uplift, detected by InSAR from Sentinel-1, warrants ongoing monitoring (gas emissions, seismometers, GPS) and hazard planning, since phreatic blasts could occur even without lava flows.
