FULL STORY ======================================================================

Nine rockets are set to launch this week from California, Florida, New Zealand, Japan, and China. SpaceX is set to launch a trio of Falcon 9s this week, delivering two batches of satellites for their Starlink constellation and a rideshare mission. JAXA is set to debut a new variant of its H3 rocket on an interplanetary mission to Mars, and China is set to launch four
payloads to orbit. Furthermore, Rocket Lab is set to launch their workhorse rocket, Electron, with a payload for HawkEye 360.



H3-24L | Martian Moons eXploration

On Monday, Oct. 19, the Japanese Aerospace Exploration Agency (JAXA)
launched the Martian Moons eXploration (MMX) mission to Mars moons Phobos and Deimos aboard the maiden flight of H3-24L. MMX lifted off from pad LA-Y2 at the Tanagashima Space Center in Japan at 19:41 UTC.

The H3 is a two-stage rocket built by Mitsubishi Heavy Industries, powered
by two cryogenic stages burning liquid hydrogen and liquid oxygen. The first stage is powered by either two or three LE-9 engines, with zero, two, or four SRB-3 boosters for additional liftoff thrust. The second stage has a single LE-5B-3 engine with the payload mounted atop and enclosed by the payload fairing. The payload fairing can come in one of three configurations: short, long, or wide. Mondays launch featured the long fairing with the specific configuration designated H3-24L for two first-stage engines, four boosters, and a long fairing.

Following payload deployment, MMX will spend about a year in transit to
Mars. Upon arrival, it will enter into a Quasi-Stationary Orbit (QSO) around Phobos. Due to the extremely low masses of the Martian moons, MMX will
operate in a QSO, allowing it to maintain a stable trajectory for an extended period while staying close to the moons.

The MMX mission will explore Phobos and Deimos, with a particular emphasis
on Phobos. Led by JAXA, MMX will observe the topography, structure, composition, and gravity of Phobos. Additional partners include NASA, Frances Center National detudes Spatiales (CNES), Germanys Deutsches Zentrum fur
Luft- und Raumfahrt e.V. (DLR), and the European Space Agency (ESA).

Riding along with MMX is the IDEFIX rover, which will be deployed from MMX
at an altitude of 40-100 m above Phobos. IDEFIX is a CNES-DLR-built rover weighing just under 23.5 kg, equipped with instruments that will aid surface observations. After deploying IDEFIX, MMX will land and conduct surface operations, most notably a sampling of Phoboss surface. MMXs two sampling instruments are designed to collect about 10 g of soil for return to Earth
for further studies.

Additional instruments aboard MMX include: TElescopic Nadir imager for GeOmOrphology (TENGOO), Optical RadiOmeter composed of CHromatic Imagers (OROCHI), Light Detection and Ranging (LIDAR), MMX InfraRed Spectrometer (MIRS), Mars-moon Exploration with GAmma rays and Neutrons (MEGANE), Circum-Martian Dust Monitor (CMDM), and a Mass Spectrum Analyzer (MSA). Following a surface stay, MMX will depart Phobos and spend some time
observing Deimos. MMX will depart Mars in 2030 for a roughly yearlong transit back to Earth. The samples collected from Phobos will land in Australia in 2031.

This mission will mark the third H3 flight of 2026. The next H3 launch is expected in the first half of 2027.



Falcon 9 | Bandwagon-5

Tuesdays launch schedule features two Falcon 9 launches, with the first flying the Bandwagon-5 mission on a southeasterly trajectory out of Space Launch Complex 40 (SLC-40) at the Cape Canaveral Space Force Station. Liftoff occurred at 7:04 AM EDT (11:04 UTC) during a one-hour launch window that opened at 6:30 AM EDT (10:30 UTC).

SpaceXs Bandwagon program is a part of the companys SmallSat Rideshare Program, which allows operators to launch on a dedicated rideshare mission aboard Falcon 9 for lower prices. Bandwagon is accompanied by the Transporter program in this role, with Bandwagon launching to mid-inclination orbits and Transporter launching into polar orbits. This will be the fifth Bandwagon mission for Falcon 9.

Aboard this flight will be 31 payloads in total, 19 from Exolaunch, two from Umbra Lab Inc., two from Tomorrow.io and Capella Space Corp, one from Planet IQ, Varda Space Industries, Planet Labs, Portal Space Systems, Viasat, and Fergani. Bandwagon-5 also launched the second of SpaceXs Starfall demonstration capsules. Payload deployment began at T+57:18 minutes and will wrap up at T+01:09:17 hours.

Falcon 9 is a two-stage, 70 m-tall, partially reusable rocket that uses nine Merlin 1D sea-level engines on its first stage and a single vacuum-optimized Merlin 1D on its second stage. Falcon 9s first stage lands either aboard an autonomous droneship or at a landing site, with its fairings being recovered and reused after flight. Both stages utilize RP-1 and LOX as propellants.

This launch was supported by booster B1085, which flew its 19th mission and landed aboard the droneship A Shortfall of Gravitas. B1085 has previously supported the GPS III SV07 (RRT-1), Blue Ghost Mission 1 / HAKUTO-R M2 Resilience, SXM-10, MTG-S1/Sentinel-4A, EchoStar XXV, SXM-11, Crew-9, Fram2, and 10 Starlink missions. This mission will mark SpaceXs 121st launch of
2026.

Falcon 9 | Starlink Group 15-15

Later on Tuesday, Oct. 20, Falcon 9 will launch from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base (VSFB) in California. The launch window opens at 5:14 PM PDT on Tuesday (22:14 UTC) and will extend until 9:14 PM PDT (2:14 UTC on Oct. 21). Flying a southeastern trajectory, Falcon 9 will carry 27 Starlink v2 Mini satellites to low-Earth orbit (LEO).

Veteran booster B1063 will support this mission, marking its 36th flight. Following stage separation, B1063 is set to land aboard SpaceXs droneship Of Course I Still Love You. B1063 has previously supported the Sentinel-6A Michael Freilich, DART, Transporter 7, Iridium 9 and OneWeb #19, Transport & Tracking Layer (Tranche 0B), NROL-113, -167, -149, NAOS (LUXEOSys) & Others, and 26 Starlink missions.

Ceres 1S | Unknown Payload

Chinas first launch of the week is set to fly on Wednesday, Oct. 21, with a Ceres 1S carrying an unknown payload into orbit. Ceres 1S will liftoff from the deck of a converted barge off the coast of Haiyang, flying on a southeast trajectory. Liftoff is currently set for 3:35 UTC, six minutes into a 21-minute launch window.
