ARTEMIS 2 SETBACK

NASA's critical wet dress rehearsal for the Artemis 2 mission was terminated at the T-5 minute 15 second mark due to a liquid hydrogen leak at the tail service mast umbilical interface. The launch control team worked to safe the Space Launch System rocket and drain its tanks. This rehearsal represents one of the final major tests before the historic mission that will send the first crew around the Moon in over 50 years.

SPACEX ORBITAL DATA CENTERS

Elon Musk announced SpaceX's acquisition of xAI and unveiled plans for up to one million satellites serving as orbital data centers. The proposal addresses ground-based data center challenges including electricity demands and water cooling needs by harnessing continuous solar power in space. Industry experts express skepticism about technical feasibility and suggest the timing may relate to SpaceX's potential IPO.

AXIOM MISSION 5

NASA ordered a fifth private astronaut mission from Axiom Space targeting launch no earlier than January 2027. The 14-day mission continues NASA's commercial space strategy, with Axiom proposing four crew members for approval. The mission includes service exchanges with NASA acquiring cold-return capability for scientific samples while Axiom purchases consumables and cargo services.

SOLAR FLARE BARRAGE

Sunspot region 4366 produced at least 18 M-class and three X-class solar flares in 24 hours, including the year's strongest X8.3 eruption. The February 1st flare triggered R3 radio blackouts across eastern Australia and New Zealand. Scientists monitor for coronal mass ejections with possible glancing Earth impact around February 5th that could produce high-latitude auroras.

IMAP MISSION START

NASA's Interstellar Mapping and Acceleration Probe officially began its two-year primary science mission on February 1st. The spacecraft's 10 instruments will map heliosphere boundaries and study particle energization and solar wind interactions. IMAP data feeds the I-ALiRT system providing near-real-time space weather observations to protect spacecraft and astronauts.

ESA OPPORTUNITIES

The European Space Agency opened applications for its 2026 Graduate Trainee Programme for recent graduates in engineering, science, IT, and business. The one-year positions with possible second-year extension offer monthly tax-exempt salaries, travel reimbursement, installation allowances, and comprehensive benefits. Candidates can submit up to three applications through jobs.esa.int. (https://jobs.esa.int/)
