2025 Welcomes SpaceX Starship Launch #7 and Blue Origin Inaugural New Glenn Flight

The fully reusable, 121-meter tall, two-stage super heavy-lift launch vehicle, Starship 33, with Booster 14 is planned to fly from from SpaceX Orbital Launch Mount A at Starbase, in Boca Chica, Texas for the 7th Test Flight of a Starship on January 10 (launch window opens 16:00 local time). After stage separation, Booster 14 will attempt to return to launch site and land vertically from where it was launched. The suborbital trajectory of Starship will see it splashdown in the Indian Ocean near Australia about an hour after launch. Images of this Starship nighttime reentry and peak-heating are planned to be taken by NASA’s Gulfstream V aircraft (NASA5 / N95NA) as Starship comes over the horizon before splashdown. The second launch pad at Starbase, Orbital Launch Mount B, is being equipped and should see a first launch this year. In December, SpaceX filed a request to have the launch site incorporated as a new city, named Starbase. Launch is now scheduled for January 8 (local time, launch window opens 01:00) for first flight of Blue Origin New Glenn NG-1 vehicle with Booster GS1-SN001 from LC 36A, Cape Canaveral SFS FL. New Glenn has 7 BE-4 engines, stands 98 meters tall and has a reusable first stage aiming for 25 missions. NG-1 will carry a Blue Ring Pathfinder, a demo platform designed to deliver payloads to GEO, cislunar and interplanetary destinations. The booster will attempt to land on ‘Jacklyn’, the first floating landing platform for New Glenn stationed in the Atlantic Ocean. (Image credits: SpaceX, The Royal Society, Blue Origin)

ISRO Moves Forward with SpaDeX Space Docking Experiment; India Science Fest Held

The space docking SpaDeX satellites DX01 (chaser) and SDX02 (target) are in LEO at ~470 km. Separated to ~20 km because of 10 meters/sec velocity difference, they wait 4 days to optimal solar orientation. Re-approaching each other, a radio frequency link will be established at ~5 km apart for docking planned January 7. Sensors developed by ISRO will guide the process using 3 guidance algorithms once the satellites are ~1.5 km apart, at speed 10mm/s. A ring extended on ‘chaser’ will retract, pulling ‘target’ towards it. Once latched, electricity transfer will be demonstrated. The satellites will undock and begin operation of 24 payloads for ~2 years. Docking is technology vital for ISRO Chandrayaan-4 mission to the Moon, and India joins USA, Russia and China with this capability. Launch was Dec 30, ISRO’s 99th from SDSC-SHAR at 13.7° N. Ananth Technologies Limited did satellite assembly, integration and testing. India Science Festival 2025 is held in Pune, an information technology and manufacturing hub, sometimes called “Oxford of the East” because of many educational institutions. Metro area population is over 7 million. 61 speakers from 10 countries are confirmed on subjects including astronomy, physics, AI, batteries, math, biology, neuroscience, R&D strategy, chemistry, engineering, writing, art, law. It is free; some events require registration. The 2024 festival saw 23,000+ attendees, 100+ speakers. (Image credits: ISRO, Foundation for Advancing Science and Technology – FAST India)
