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

SpaceX is back with another active week, with five Falcon 9 rockets
launching from two different launch sites and Starships eighth test flight launching from Texas. Rocket Labs Electron rocket and the Curie kickstage are also anticipated to fly along with Arianespaces Ariane 6 from the Guiana
Space Center in French Guiana.

Ariane 6 kicks off the week by launching high-resolution reconnaissance satellites for the French Space Agency, followed by Starships eighth flight. Following that, Falcon 9s week begins with the Starlink Group 12-21 launch, adding more capability to the internet system. Then, the SPHEREx & PUNCH mission will head to space to enhance our understanding of the Big Bang and observe the Suns corona. Next on the manifest is Starlink Group 12-16, and then Starlink Group 11-7. Finally, Transporter-13 will deliver at least 40 payloads from various providers to a Sun-synchronous orbit, and Electron is expected to finish the week taking iQPSs SAR satellites to low-Earth orbit.



Ariane 62 | CSO-3

Arianespace is launching Ariane 6 to a Sun-synchronous orbit (SSO) on March 5 at 16:24 UTC after the initial launch attempt on March 3 was scrubbed due to further operations needed on a ground means interfacing with the launcher. Ariane 62 will carry the CSO-3 high-resolution reconnaissance satellite into an 800 km SSO from pad ELA-4 at the Guiana Space Center. (1/2) Flight VA263: Postponement of the launch

Due to further operations needed on a ground means interfacing with the launcher, the launch is postponed.

The new launch date will be announced following the completion of these operations.

CSO-3 will be deployed around 66 minutes into flight and will complete the
CSO constellation for the MUSIS program. These satellites were planned to be flown on Soyuz but changed providers due to geopolitical challenges. This mission will be Arianespaces 300th mission of all time and the first of an expected five in 2025.

The Ariane 6 flying this mission is of the 62 variant, meaning two strap-on solid rocket boosters will be attached to the core stage. Ariane 6s liquid stages utilize liquid hydrogen and liquid oxygen, which are burned through
the first stage Vulcain 2.1 engine and the second stage Vinci engine. The rocket flew for the first time on July 9, 2024. This will be its second mission.

Starship | Flight 8

The eighth flight test of Starship is expected to launch on March 5 at 5:30
PM CST (23:30 UTC) from SpaceXs launch site in Starbase, Texas, after an attempt on March 3 was scrubbed due to subpar pressure in the Raptor engines. This flight is expected to achieve many of the same goals set for the precluded seventh flight, with some minor differences.

Flight 8 will begin with a successful launch off of Orbital Launch Pad A at Starbase, during which Super Heavy will ignite 33 Raptor engines. Then, at T+ 2:40 minutes, Booster 15 and Ship 34 will separate via hotstaging, and Super Heavy will return to Starbase to attempt to be caught by the catch tower for the third time. Ship 34 will continue to fly to a suborbital trajectory, releasing four Starlink simulators while coasting in space. This will be the first time a Starship will attempt to release any payload to space. Ship 34 will later relight a single Raptor engine for reentry and attempt to splashdown in the Indian Ocean.

Falcon 9 | Starlink Group 12-21

The first Starlink mission of this week is scheduled to launch on March 5 at 1:00 AM EST (6:00 UTC) from Cape Canaveral Space Force Station (CCSFS) at SpaceXs Falcon launch site, Space Launch Complex 40 (SLC-40). This mission will place 21 Starlink v2 Mini satellites into low-Earth orbit (LEO) at 284
by 294-km inclined by 43 degrees. 13 of the 21 satellites will be equipped with Direct-to-Cell capabilities.

The booster for this mission is currently unknown, but it will land on one of SpaceXs autonomous droneships, A Shortfall of Gravitas, stationed on the east coast. This droneship will likely be positioned about 600 km downrange in the Atlantic Ocean, where it will recover the booster.

Falcon 9 | SPHEREx & PUNCH

SpaceX is set to launch two significant NASA science missions into SSO, allowing for a more detailed study of our solar system and the universe than ever before. The Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) mission will examine the broader aspects of the universe to help address many unknowns in astrophysics, and
the Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission will investigate solar winds ejected from the Suns corona.

Falcon 9 will launch these two telescopes from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base on March 6 at 7:09 PM PST (3:09 UTC
on March 7). Falcon booster B1088 will carry the telescopes to a 700 km SSO. Following liftoff, the first stage is expected to land at Landing Zone 4 (LZ-4), which would complete its third mission. SPHEREx space observatory after environmental testing (Credit: NASA)

One of SPHERExs main objectives is to investigate cosmic inflation a phenomenon that occurred less than a second after the Big Bang and is responsible for the universes expansion into a flat plane rather than a perfect sphere. Cosmic inflation also clarifies why pockets of highly dense material could coalesce in some regions of the universe, forming galaxies. Astrophysicists can use the data from SPHEREx to piece together the puzzle of how the universe was formed.

SPHEREx will measure the total glow from all galaxies, including those too small or distant for other telescopes to detect easily. This will help astrophysicists better understand the universes overall size and density. An additional objective for SPHEREx is to aid in searching for essential
building blocks of life within the Milky Way. The telescope is designed to detect frozen oxygen and water molecules in interstellar clouds where stars and planets form. This could help identify regions of the universe that are abundant in these molecules, which are more likely to support life as we know it. After launch, our SPHEREx telescope will map the whole sky and help us answer some big questions about the universe. Watch to learn how SPHERExs
wide field of view and the ability to measure over 100 colors will give us a big-picture view of the cosmos like none before. pic.twitter.com/8DZvJlev8u

The PUNCH mission is comprised of four suitcase-sized small satellites intended to study the Suns corona, the formation of solar wind, and solar winds effects on the heliosphere. There are several theories on how solar
wind is formed, mainly focusing on the expansion of plasma that was heated
and given enough energy to break free of the Suns gravity and flow along the magnetic fields of the Sun. PUNCH will help confirm this theory and investigate the origins and evolution of solar wind.

This mission will also help track coronal mass ejections, which could pose risks to Earth or in-orbit missions. The four satellites will work together
to create the most expansive field of view of the sky of any Sun-focused mission, helping broaden our knowledge of the Sun and finding ways to keep future satellites safer from coronal ejections. Our Sun creates a solar wind that fills the solar system!

NASA will take a PUNCH at solving how solar wind is created with four small satellites. PUNCH will launch as a rideshare with SPHEREx no earlier than

Falcon 9 | Starlink Group 12-16

A Falcon 9 will liftoff from SLC-40 on March 8 at 8:41 AM EST (13:41 UTC) with 21 Starlink v2 Mini satellites, 13 having Direct-to-Cell capabilities,
on a southeastern trajectory, inclined by 43 degrees.

The mission plan is similar to Starlink Group 12-21, which is expected to launch under 57 hours before this mission. This is an incredible turnaround time for SLC-40, as SpaceX is currently reserving Launch Complex 39A (LC-39A) for its upcoming Crew-10 crewed mission to the International Space Station (ISS). The booster for this mission is currently unknown, but is expected to land on one of the two east coast droneships downrange in the Atlantic Ocean.

Falcon 9 | Starlink Group 11-7

Falcon 9 is expected to continue its run of launches with the Starlink Group 11-7 mission, which will be the third Starlink and fourth Falcon 9 mission in four days. Starlink Group 11-7 is set to launch on March 8 at 6:00 PM PST ( 2:00 UTC on March 8) from SLC-4E with approximately 20 Starlink v2 Mini satellites. Falcon 9 will launch on a southeastern trajectory, inclined by 53.16 degrees.

The booster is currently unknown, but will touchdown on SpaceXs autonomous droneship Of Course I Still Love You, which will be around 600 km downrange
in the Pacific Ocean. This is the only droneship stationed on the west coast.



Falcon 9 | Transporter 13

Transporter 13 is set to be SpaceXs final Falcon 9 launch of the week, and
is set to liftoff on March 8 at 10:39 PM PST ( 6:39 UTC on March 9) from SLC-4E. Transporter is a SpaceX rideshare program that facilitates the transportation of payloads from various providers to SSO. Over 40 satellites are anticipated to be deployed during this mission. These missions allow smaller satellite providers to launch satellites into space at a relatively low cost of $300,000 for up to 50 kg to SSO.

The booster for this mission is currently unknown. Following launch, the booster will return to the launch site and land at LZ-4, allowing for a more rapid refurbishment before its next mission.

Electron/Curie | The Lightning God Reigns

Rocket Lab is scheduled to launch its third mission of 2025 on Monday, March 10, at 1:00 PM NZDT (24:00 UTC) from Rocket Labs Launch Complex 1B (LC-1B) at the Mhia Peninsula in New Zealand. The mission, titled The Lightning God Reigns, will deploy iQPSs synthetic aperture radar (SAR) satellites into LEO. These satellites are designed to capture high-resolution images of Earth.
iQPS aims to have 24 of these satellites in orbit by 2027.

This will be the first of eight Electron launches to carry iQPSs SAR satellites. This collaboration with Rocket Lab will help to fill out the constellation to a total of 36 satellites orbiting Earth.
