This week options a number of missions scheduled to launch from websites all world wide. China has launched its newest cargo resupply mission to the Tiangong house station, whereas Gilmour House had anticipated to try the maiden launch of its Eris rocket from Australia – that is now delayed into subsequent week.
As ordinary, SpaceX is about to have a busy week of launching web satellites. The corporate’s schedule consists of two Starlink missions along with a batch of Kuiper satellites for Amazon’s Mission Kuiper web constellation – a direct competitor of Starlink – atop a brand new booster taking its maiden flight.

The most recent cargo provide mission headed to China’s Tiangong house station lifted off on Monday, July 14, at 21:40 UTC. A Chang Zheng 7 rocket lofted the Tianzhou 9 (or “heavenly ship”) cargo car from pad LC-201 on the Wenchang House Launch Website on the island of Hainan.
Prematurely of this mission, the earlier Tianzhou 8 car undocked from the Tianhe aft port on the station on July 9 and broke up upon reentry into Earth’s environment. Tianzhou 9 docked to Tiangong on the Tianhe port roughly three hours after liftoff. Onboard have been meals, garments, and different consumables for the Shenzhou 20 crew, along with life assist provides, scientific experiments, propellants for stationkeeping, and different gadgets for station upkeep.
Additionally aboard have been two upgraded Feitian extravehicular exercise (EVA) fits, which can change a pair that have been disposed of on Tianzhou 8. The brand new fits have a lifespan of 20 usages over 4 years. The outgoing pair of fits had already far exceeded their designed 15-use lifespans and have been one spacewalk shy of this upgraded aim.
Tianzhou 9 is anticipated to spend six to seven months on the station and measures 10.6 m lengthy and three.35 m in diameter. The car docks autonomously and may carry as much as 7,400 kg of cargo. SpaceX’s Cargo Dragon, by comparability, can carry round 6,000 kg of pressurized and unpressurized cargo, whereas Cygnus can carry 3,750 kg. Each of those autos are as a consequence of fly resupply missions to the Worldwide House Station (ISS) aboard Falcon 9 autos within the subsequent two to a few months.
Falcon 9 | Starlink Group 15-2
A Falcon 9 launched a batch of 26 Starlink v2-Mini web satellites into low-Earth orbit (LEO) on Tuesday, July 15. Liftoff passed off from House Launch Complicated 4 East (SLC-4E) on the Vandenberg House Drive Base in California on the prime of a launch window at 7:05 PM PDT (02:05 UTC on Wednesday, July 16).
Regardless of the mission title, SpaceX had already launched eight different flights into the Group 15 shell of its Starlink constellation. Each launch into this shell has occurred from SLC-4E, and this was the primary launch from the pad because the Group 15-7 mission in late June, which marked the five hundredth flight of Falcon 9.
Following deployment, the satellites will make their solution to an orbit at 535 km altitude, inclined 70 levels. Booster B1093 supported this mission on its fourth flight and efficiently landed downrange on the west coast droneship Of Course I Nonetheless Love You. Thus far, it had lofted three different batches into the Group 15 shell of the Starlink constellation. Firstly of the week, SpaceX had launched 9,165 Starlink satellites. Of those, 1,197 have reentered Earth’s environment, and seven,028 have moved into their operational orbits.
A yr has now handed because the second-stage engine didn’t restart throughout SpaceX’s Starlink Group 9-3 mission, ending a streak of 325 consecutive profitable missions for the corporate. SpaceX has since rebuilt the depend of consecutive Falcon missions to just about half that through the 12 months since that anomaly on July 12, 2024 — the streak stood at 149 on the finish of final week’s Business GTO-1 mission. SpaceX, due to this fact, reached a notable milestone with Starlink Group 15-2, marking the one hundred and fiftieth profitable mission in a row.

Falcon 9 | Mission Kuiper (KF-01)
SpaceX has launched its first contracted batch of Amazon’s Kuiper satellites on Wednesday, July 16, from House Launch Complicated 40 (SLC-40) on the Cape Canaveral House Drive Station in Florida.
Liftoff occurred at 2:30 AM EDT (06:30 UTC), carrying 24 of the satellites to LEO. The primary stage supporting this mission was B1096 on its maiden flight. The booster efficiently landed on the SpaceX droneship A Shortfall of Gravitas after taking a northeasterly trajectory.
Kuiper satellites are deliberate to occupy 98 orbital planes in layers at altitudes of 590 km, 610 km, and 630 km. To satisfy expectations in its license from the Federal Communications Fee (FCC), the complete constellation of three,236 satellites have to be launched by the tip of July 2029. The extra urgent deadline is in a single yr’s time, when Amazon is required to have deployed half of its constellation — 1,618 of the satellites — by July 30, 2026.
To this finish, two additional launches have been booked aboard Falcon 9 and can fly within the subsequent quarter, 12 are booked aboard Blue Origin’s New Glenn, and 18 aboard Arianespace’s Ariane 6.
The United Launch Alliance’s (ULA) Atlas V has already lofted two preliminary batches of 27 Kuiper satellites, with one batch launching in April and one other in June. ULA will now swap to its Vulcan rocket, within the VC6L configuration with six strong boosters, to hold not less than yet another batch to LEO by the tip of the yr. ULA has been contracted to launch 38 missions for the constellation.
As famous above, this mission is because of develop into the one hundred and fiftieth consecutive profitable Falcon mission because the anomaly through the Starlink Group 9-3 mission this time final yr.
Falcon 9 | Starlink Group 17-3
A second Falcon 9 launch from SLC-4E in Vandenberg lifted off the pad on Wednesday, July 16, at 8:52 PM PDT (03:52 UTC on July 17), roughly midway by the four-hour launch window. Starlink Group 17-3 was the second mission to hold 24 into the Group 17 shell of the Starlink constellation, the primary of which launched from this similar pad nearly two months in the past. This had been the primary Starlink launch to a Solar-synchronous orbital inclination in over two years.
The booster supporting this mission was B1082 on its 14th flight. Lively for a yr and a half, this primary stage has supported two authorities missions and the OneWeb 20 launch along with a collection of different missions for the Starlink constellation.
The booster landed efficiently downrange on the droneship Of Course I Nonetheless Love You round eight minutes into the mission. As with the earlier Group 17 mission, Falcon 9 flew nearly immediately south into an orbit with an inclination of over 97 levels. Following deployment, the satellites will make their solution to an orbit at an altitude of 535 km.

Two extra second-generation satellites massing round 3,400 kg are as a consequence of fly aboard a Falcon 9 and additional construct out the 03b mPower community for SES-owned 03b Networks. Liftoff is scheduled on the prime of a two-hour window which opens on Monday, July 21 at 5:12 PM EDT (21:12 UTC) from SLC-40 on the Cape Canaveral House Drive Station in Florida.
SpaceX has beforehand lofted 4 different pairs of those satellites right into a medium-Earth orbit because the first two launched in December 2022. The latest launch for the constellation was in late December 2024, when the booster supporting this mission, B1090, made its debut.
This would be the sixth flight for this primary stage, which has additionally supported the Crew-10 and Bandwagon-3 missions earlier this yr. The booster is anticipated to land on the deck of the SpaceX droneship Simply Learn The Directions, which will likely be ready downrange within the Atlantic Ocean.

Gilmour House was anticipated to make a second try on the maiden launch of its Eris small satellite tv for pc rocket on Wednesday, July 16, at 7:30 AM AEST (21:30 UTC on Tuesday, July 15). The try has been pushed again to no sooner than July 26, nonetheless, as a consequence of operational delays and higher wind forecasts for the remainder of this week.
The corporate stood down from its earlier try, which was scheduled for Could 16, after the fairings have been prematurely triggered by the separation system throughout in a single day launch preparations. An sudden energy surge from different gadgets downstream had prompted the car to close down, inflicting the difficulty, which has since been mitigated.
The launch will happen from the Bowen Orbital Spaceport at Abbot Level, north of the coastal city of Bowen. As the symbol on the rocket physique proudly declares, the three-stage launcher is “Australian-made.” TestFlight 1 is poised to develop into the primary orbital launch from Australian soil carried out by a sovereign-built car.

Akin to Rocket Lab’s Electron, Eris stands a bit of taller at 25 m in peak. The car additionally has a barely bigger 1.5 m fairing and boasts a payload mass of as much as 215 kg to a 500 km Solar-synchronous orbit, or 305 kg to 500 km equatorial orbits. The primary stage is propelled by 4 Sirius engines — a proprietary hybrid engine that makes use of a 3D-printed strong gasoline grain and hydrogen peroxide because the oxidizer. A single Sirius engine powers the second stage. A profitable orbital launch would even be the primary for a hybrid rocket design.
Gilmour House introduced final week that it had signed a brand new partnership with Tokyo-based House BD that can open up devoted and rideshare alternatives aboard its Eris rocket and ElaraSat platform for Japanese and international satellite tv for pc prospects.
