NASA lays out an Earth-orbit dress rehearsal with two lunar landers

Artemis III, targeted for 2027, will spend 14 to 17 days in low Earth orbit testing SLS, Orion, New Glenn, Starship and Blue Origin's Blue Moon test lander. New Glenn launches Blue Moon first, then SLS sends the crew up in Orion. Orion docks with Blue Moon on day 3 and the crew boards it on days 4 and 5 to check life support and other systems. Starship launches on day 6 and docks with Orion for about two hours on day 8, with no crew transfer. For the Artemis IV landing at the end of 2028, NASA is weighing Starship HLS and Blue Origin's Mark 2 lander and has not chosen. Administrator Jared Isaacman told staff Artemis III is about 90 days behind schedule on paper.

U.S. Headlines
  1. SpaceX · Starbase, Texas

    SpaceX will try to catch both Starship stages on Flight 15

    Elon Musk said on SpaceX's third-quarter earnings call on October 20 that the next Starship flight, expected in November, will try to catch both Super Heavy and the Ship with the launch tower's arms. It would be the first full recovery of an orbital launch vehicle. SpaceX has caught Super Heavy three times in 14 flights but has never tried to catch the Ship. Musk called success "more likely than not." SpaceX also reported $14.6 billion in quarterly revenue and $4.4 billion in net income.

  2. Xona Space Systems · Burlingame, Calif.

    Xona raises $250 million for its commercial GPS constellation

    Xona Space Systems closed a $250 million Series D led by Steve Jurvetson's Future Ventures, at a $2.45 billion valuation, bringing its total raised since 2019 to more than $570 million. The money will speed production of Pulsar, a planned constellation of about 258 satellites offering precise, jam-resistant navigation signals. Six Pulsar satellites flew on SpaceX's Bandwagon-5. Xona aims to start early timing service next year and full service in 2027, and to be able to build 50 satellites a year by the end of 2027.

  3. U.S. Space Force · Anduril · Los Angeles

    Space Force signs the first working contracts for its commercial space reserve

    Space Systems Command awarded six short-term contracts worth $1.37 million in total to space-tracking firms under the Commercial Augmentation Space Reserve (CASR), which is modeled on the airline reserve fleet the military can call on in wartime. The winners are EOS Space Systems, NorthStar Earth and Space, InTrack Radar, Anduril (through ExoAnalytic), Slingshot Aerospace and LeoLabs. Officials said the awards will help measure military demand for commercial space domain awareness data. Legal questions over service denial and payment for satellites lost in a conflict remain open.

International Headlines
  1. JAXA · Mitsubishi Heavy Industries · Tanegashima, Japan

    Japan's MMX is on its way to bring home a piece of Phobos

    An H3 rocket launched JAXA's Martian Moons eXploration mission on October 19 US time (October 20 in Japan). MMX should reach Mars in August 2027, study Phobos and Deimos from orbit, land on Phobos no earlier than December 2028 and return samples to Australia in 2031. It carries the DLR and CNES rover Idefix and two NASA contributions: the MEGANE spectrometer from Johns Hopkins APL and Honeybee Robotics' P-Sampler.

  2. ICEYE · Russia · Earth orbit

    A Russian military satellite shadows an ICEYE radar satellite

    Cosmos 2612 may have passed within a few hundred meters of ICEYE-X36 on October 18 after weeks of maneuvers that put it in the same orbit, according to independent trackers. ICEYE has supplied radar imagery to Ukraine since 2022 but has not said whether X36 is part of that work. The company said it is tracking the satellite closely.

  3. ISRO · Mahendragiri, India

    ISRO fires the gas generator of its new methane engine

    ISRO ignited the full-scale gas generator of its 1,100-kilonewton LME-1100 engine on October 9, with the complete engine due by mid-2027 for hot-fire qualification tests. It has also finished the design of a 2,400-kilonewton methane engine using full-flow staged combustion, the cycle in SpaceX's Raptor, for a future heavy-lift rocket meant to support India's crewed Moon landing.
