SpaceX Starlink 17-22 — 600th Booster Landing Attempt

• Vehicle: Falcon 9 (booster B1082)
• Status: Launched April 19, 2026
• Details: SpaceX attempted its 600th Falcon 9 booster landing during the Starlink 17-22 mission, lofting 25 satellites from Vandenberg Space Force Base. The milestone underscores SpaceX's extraordinary reusability record, which has dramatically reduced the cost of orbital access since the program began.

SpaceX Dual Starlink Launches — 19 Hours Apart

• Vehicle: Falcon 9 (two separate missions: B1080 from CCSFS, B1082 from VSFB)
• Status: Both launched April 14, 2026
• Details: SpaceX launched two Falcon 9 rockets just 19 hours apart on April 14, deploying batches of Starlink satellites from Florida (Starlink 10-24) and California (Starlink 17-27). The rapid cadence illustrates SpaceX's aggressive pace to expand its Starlink broadband constellation.

China: Jielong-3 & Kinetica-1 Solid Rocket Launches

• Vehicle: Jielong-3 and Kinetica-1 (solid-fueled commercial rockets)
• Status: Both launched week of April 14, 2026
• Details: A pair of Chinese commercial solid rocket launches delivered a total of nine satellites to orbit — one internet test satellite aboard Jielong-3, plus eight remote sensing satellites aboard Kinetica-1. The missions represent continued momentum in China's commercial launch sector and expand both internet and Earth observation capabilities.

Starship V3 Engine Test & ESA Crew Launch Plans

• Vehicle: Starship (SpaceX) / ESA crew systems (separate developments)
• Status: Test-fired / Planning stage (as of ~April 17, 2026)
• Details: Ars Technica's Rocket Report this week noted that SpaceX test-fired a Starship V3 engine, a key step toward next-generation Starship flights. Separately, ESA is taking a "tentative step" toward crewed launch capability, a significant policy development for the agency that has long relied on other nations' vehicles for human spaceflight.

Commercial Space

• Blue Origin: The company has paused its New Shepard suborbital tourism program with operations suspended for at least two years beginning in early 2026, as engineering resources are redirected toward lunar lander development. Blue Origin continues development of its New Glenn orbital launch vehicle and BE-4 rocket engines, with upcoming New Glenn flights on the manifest.

• SpaceX IPO Preparations: Reuters reported (April 1, 2026) that SpaceX is preparing to file for an initial public offering, with infrastructure at Starbase, Texas being readied. The filing would mark a landmark moment for the private space industry. While the Reuters article falls just outside our coverage window, the broader IPO story continues to shape commercial space investment discussions this week.

Science & Discovery

• James Webb Space Telescope — Planet/Star Boundary Redefined: NASA's Webb telescope has published a finding that redefines the dividing line between planets and stars. Unlike planets (which form bottom-up from clumping rock and ice), certain low-mass objects blur the traditional boundary. The result, published around April 14–15, 2026, has significant implications for how astronomers classify brown dwarfs and giant gas planets, and for understanding planetary system formation across the galaxy.

• Asteroid Apophis — 2029 Flyby Confirmed Visible to Naked Eye: Scientists have calculated the trajectory of asteroid (99942) Apophis, which will pass within approximately 32,000 km of Earth's surface on April 13, 2029 — close enough to be visible to the naked eye. Updated calculations also clarify whether any impact risk remains (current models show no impact threat for this pass). The event is drawing major interest from planetary defense researchers worldwide.

• JPL Budget Threat: The Trump administration's proposed FY2027 budget request to Congress would cut NASA funding further, posing renewed challenges to NASA's Jet Propulsion Laboratory in La Cañada Flintridge, California. JPL manages numerous deep-space missions; cuts could affect future planetary science programs.

Artemis II Launch Day Updates - NASA

Upcoming Launch Schedule

Note: Specific dates subject to change; verify at Spaceflight Now's launch schedule for the latest.

What to Watch This Week

• Blue Origin New Glenn Flight 3: Blue Origin is expected to conduct the third flight of its New Glenn rocket soon, this time with a reused booster — a critical reusability milestone for the company as it works to compete with Falcon 9's cadence.
• NASA FY2027 Budget Debate: Congressional response to the administration's proposed NASA cuts — particularly for JPL and science missions — is expected to develop over the coming weeks; watch for committee hearings and statements from the planetary science community.
• Artemis Program Next Steps: Following Artemis II's successful crewed lunar flyby earlier this month, NASA and its international partners are expected to announce timelines and mission objectives for the Artemis III Moon landing attempt.
