Launch Roundup: New Shepard to simulate lunar gravity, India and Japan launch navigation satellites

by Martin Smith

This week’s schedule has a mix of orbital and suborbital missions launching from seven different sites around the globe. In addition to launches from the Florida space coast, India and Japan have both launched navigation satellites. Rocket Lab is launching another batch of satellites for its French customer, Kinéis, while SpaceX has launched a next-generation replacement communications satellite for Spanish operator Hisdesat.

An uncrewed New Shepard flight, which will conduct experiments for NASA and others in simulated lunar gravity, has now been delayed until next week. SpaceX launched three missions, using each of its three active launch sites. These included the first expendable Falcon 9 launch since the Hera mission last October.

The week also closes the month of January which will have seen 21missions launched around the world in total. The month saw the debut of Blue Origin’s New Glenn heavy lift vehicle, while the maiden launch of China’s Chang Zheng 8A carrier has now slipped from this week into early February.

Five days after the second catch of a Starship booster, January also saw the 400th propulsive landing of a Falcon booster. This milestone was reached last week on the Starlink Group 11-8 mission which launched from Vandenberg Space Force Base on Tuesday, Jan. 21.

Three days later, the Starlink Group 11-6 mission from the same site also broke pad turnaround records by 17 hours. SLC-4E’s turnaround record is now set at 2 days, 22 hours, 21 minutes and 10 seconds. The droneship Of Course I Still Love You also set a fleet turnaround record, now under 3 days, with SpaceX’s Kiko Dontchev citing the same statistic of 2 days and 22 hours for this record.

Falcon 9 Block 5 | Starlink Group 12-7

SpaceX started the week with its eighth Starlink mission of the year, launching from SLC-40 at the Cape Canaveral Space Force Station in Florida. Liftoff occurred on Monday, Jan. 27, at 5:05 PM EST (22:05 UTC), towards the end of a four-hour launch window. A Falcon 9 carried 21 Starlink v2 Mini satellites into low-Earth orbit, including 13 with Direct to Cell capabilities.

Among the Starlink satellite designs being launched now is a new, lighter optimized version of the v2 Mini, which masses around 575 kg each. The lighter design will enable more satellites to be carried per mission. Last week’s Group 11-8 mission carried a record 27 of this newer design, while it’s possible that future vehicles may carry as many as 29.

Booster B1076 supported this mission on its 20th flight – the ninth booster to have reached this milestone. It successfully landed on the autonomous droneship A Shortfall of Gravitas, which was stationed downrange. This booster has been active since late 2022, beginning with the launch of a Dragon spacecraft to the International Space Station on its first flight for the CRS-26 mission. It has since lofted a variety of satellites, including SXM-9, OneWeb, 03b mPOWER, Intelsat 40e, Ovzon, Eutelsat 36D, Turksat 6A, Worldview Legion 3 and 4, and ten other Starlink missions.

GSLV Mk 11 | NVS-02 (IRNSS-1K)

The Indian Space Research Organization (ISRO) has launched a regional navigation satellite atop a Geosynchronous Satellite Launch Vehicle (GSLV) Mark II. The launch, ISRO’s first of the year, was originally scheduled for Sunday, Jan. 26, and was successfully launched on Wednesday, Jan. 29, at 00:53 UTC. The GSLV vehicle left the Second Launch Pad at the Satish Dhawan Space Centre in India, heading due East, as is usual for geosynchronous orbits.

The payload, NVS-02, is the ninth satellite in the Navigation with Indian Constellation (NavIC) and the second in the series of five planned next-generation satellites that will complement the existing NavIC base layer. The satellite’s range will extend for around 1,500 km beyond the Indian sub-continent and is both compatible and interoperable with the Global Positioning System (GPS) and Galileo systems.

There are two specific payloads aboard the satellite, independently providing ranging and navigation functionality. The satellite’s Standard Positioning Service (SPS) will provide positioning accuracy better than 20 m and a timing accuracy better than 40 ns over the Indian landmass, which is its primary service area. NVS-02 carries an extremely accurate atomic clock that counts the oscillations of rubidium-87 atoms to measure each second. Its predecessor was the first Indian satellite to fly with an indigenous atomic clock. Powered by two solar arrays, the satellite has a projected lifespan of ten years.

Standing 51.7 m tall with a 4 m diameter fairing, the GSLV Mark II shares components with the Polar Satellite Launch Vehicle (PSLV). The first stage is a solid rocket motor, while the second uses a liquid-fueled Vikas engine. The upper stage is cryogenic, powered by a CE-7.5 engine burning liquid hydrogen and oxygen. Four liquid-fueled L40H strap-on boosters will assist the first stage on its initial ascent.

Falcon 9 Block 5 | SPAINSAT New Generation I

A Falcon 9 has launched the first of two telecommunications satellites to replace the SpainSat and XTAR-EUR satellites currently in orbit. The SpainSat New Generation (NG) satellites will provide coverage for the Spanish Armed Forces across two-thirds of the planet, spanning the American continent to East Asia.

The launch took place on Tuesday, Jan. 28 at 8:34 PM EST (01:34 UTC on Jan 29), leaving pad LC-39A at the Kennedy Space Center in Florida and lofting the payload into a geostationary transfer orbit. Following deployment, the spacecraft will replace the XTAR-EUR satellite in a geostationary orbit.

Using a technique known as beam hopping, the satellite can generate and move multiple X-band communication beams at high speed. The European Space Agency (ESA) described the antennas onboard as “the most challenging active antennas to have been developed in Europe so far” when details of the project were announced in the summer of 2023.

The satellites are based on Airbus’ reliable Eurostar Neo platform and will bring updated communications functionality as well as a high level of security and resilience. They have been built by Airbus Space and Thales Alenia together with a consortium of Spanish space companies for operator Hisdesat. With an operational life of around 15 years, the satellites interconnect military X and Ka-band traffic to allow band crossover and also operate in the UHF band.

Hazard notices indicated this mission was to be the first expendable Falcon 9 launch since the Hera mission last October. The booster supporting this mission was B1073 on its 21st and final flight. Active since May 2022, this booster had launched Bandwagon-1, Hakuto-R, Amazonas Nexus, 13 Starlink missions, and a cargo mission, CRS-27, to the International Space Station, amongst others. A second satellite, SpainSat NG II, is also planned to launch atop a Falcon 9 later this year and will replace the current SpainSat in geostationary orbit.

New Shepard | NS-29

This week, Blue Origin plans to fly the third mission of its suborbital New Shepard vehicle in just over three months.  Unlike recent missions, however, there will be no crew on this flight. Instead, 30 payloads will be performing a variety of tests that will take advantage of a simulated lunar gravity.

New Shepard is expected to launch from Blue Origin’s Launch Site One in West Texas. The first attempt on Tuesday, Jan. 28 was put into a hold at T-10 minutes while the team assessed weather conditions and attempted to troubleshoot a vehicle avionics issue. This hold lasted for over an hour and a half, after which Blue Origin announced that the issues would extend beyond the launch window. The mission was briefly rescheduled for Thursday, Jan. 30 but is now anticipated next week on Tuesday, Feb. 4 when the launch window opens at 9:30 AM CST (15:30 UTC).

NASA is flying 17 technologies on the flight, which cover a broad range of experiments from dust mitigation and lunar habitats to in-situ resource utilization. The payloads will experience around two minutes of simulated lunar gravity generated when the capsule RSS H.G. Wells is put into a spin. The onboard reaction control thrusters will spin the capsule at around 11 revolutions per minute, simulating the Moon’s gravity, which is around one-sixth of that on Earth.

Simulating lunar gravity allows NASA researchers to test various innovations that form part of the Artemis program and will inform planetary exploration and habitation. Previously, lunar simulations were limited to around 20 seconds on parabolic flights or a fleeting few seconds in a centrifuge drop tower. Blue Origin CEO Dave Limp posted a message noting that the company can adapt this capability to closely mirror Mars and other solar system gravity environments in the future.

One experiment is attached externally to the booster, which recently made its debut as the second active booster in the New Shepard fleet. The Film Evaporation MEMS Tunable Array (FEMTA) is a micropropulsion alternative for small satellites developed by Purdue University. FEMTA uses water surface tension to provide low power but highly tunable attitude control and could enable in-situ resource utilization for its propellant.

A further 29 other experiments will fly internally in the capsule. Honeybee Robotics, part of the Blue Origin family, is focused on excavating and processing lunar regolith and has four payloads on board. NASA’s experiments include the testing of dust-tolerant technology to move lunar regolith particles using dynamic electric fields and other methods to move regolith vertically in vacuum conditions. Others will inform the creation of lunar regolith simulants and test drum technology which could be used for robotic excavation on the lunar surface in reduced gravity.

Additional experiments will test low-mass pneumatic techniques to liberate dust from rocks and planetary surfaces as well as from equipment such as solar panels. They will test how the dust settles in lunar gravity and how it departs from spacesuit fabric. Also taking advantage of the lunar gravity simulation are fluid physics experiments that will inform the thermal management of electronic systems and could improve the management of gases and liquids in space. Also onboard, the Draper Multi-Environment Navigator (DMEN) is a small, light, and low-power solution for providing location and wayfaring data to support entry, descent, and accurate lunar landings.

New Shepard will have launched over 175 payloads at the completion of this mission.

Falcon 9 Block 5 | Starlink Group 11-4

This was the second of three Starlink missions this week. Liftoff took place on Friday, Jan. 31 at 2:48 PM PST (22:48 UTC) from SLC-4E at the Vandenberg Space Force Station in California. The mission carried another batch of 22 Starlink v2 Mini satellites into low-Earth orbit. SpaceX has launched over 3,000 of the v2 design Starlink satellites to date.

Booster B1075 flew for the 17th time on this mission and successfully landed on the droneship Of Course I Still Love You, waiting downrange in the Pacific Ocean. This was SpaceX’s 420th recovery attempt. The booster had previously supported the Transporter 11, SARah 2 & 3, and 12 other Starlink missions, in addition to the first Transport & Tracking Layer mission for the United States Space Force (USSF).

Starlink users worldwide have reached 4.6 million, spanning 118 countries and territories. This has increased significantly from 3 million just seven months ago. At the start of this week, SpaceX had launched 7,800 Starlink satellites, of which 816 have re-entered and 6,242 have moved into their operational orbit.

H3-22S | Michibiki 6

A Mitsubishi H3 rocket launched from pad LA-Y2 at the Tanegashima Space Center in Japan on Sunday, Feb. 2 at 08:30 UTC. This flight had been delayed by a day due to thunderstorms around the launch site. In the H3-22S configuration, the vehicle has two additional side boosters and a shorter fairing. This configuration has now flown five times since its maiden launch in March 2023, conducting three successful missions last year.

The Quasi Zenith Satellite 6 (QZS-6), or Michibiki 6, satellite is part of the Quasi Zenith Satellite System (QZSS) which operates in geosynchronous orbits, providing navigation and positioning services.

The satellite masses around 4,900 kg and also carried a classified space situational awareness payload for the United States Space Force (USSF). The constellation broadcasts GPS-interoperable and augmentation signals as well as original QZSS signals. The satellite improves on the 5 to 10 m accuracy of the Global Positioning System (GPS), claiming centimeter-level accuracy, and has a design life of at least 15 years.

Unveiled last November at Mitsubishi’s Kamakura Works, QZS-6 will join four others in the existing constellation. Three of these are in a quasi-zenith orbit, and the other is in a geostationary orbit, where this latest satellite is also headed. The constellation will grow to seven by 2026, when it will become operational, with plans to develop an 11-satellite system later.

Falcon 9 Block 5 | Starlink Group 12-3

The third Starlink mission of the week was due to lift off from SLC-40 at the Cape Canaveral Space Force Station. The launch is now rescheduled, however, to Tuesday, Feb. 4 at 3:37 AM EST (08:37 UTC). The Falcon 9 will head southeast, carrying a batch of Starlink v2-Mini satellites to low-Earth orbit, inclined 43 degrees.

Despite its numbering, this will be the eighth launch into this Group 12 shell of the constellation. Booster B1069 will be taking its 21st flight and has spent the last 20 months flying only Starlink missions. The booster made its debut in late 2021, carrying the CRS-24 cargo mission to the International Space Station, which also gave SpaceX its 100th landing of an orbital booster. B1069 has lofted OneWeb, SES, and Hotbird satellites in addition to 16 Starlink missions prior to this one. Around eight minutes into the flight it is expected to land on the deck of the autonomous droneship Just Read The Instructions, which will be waiting in the Atlantic Ocean.

Electron / Curie | IoT 4 You and Me

This mission will be the fourth of five planned launches, each carrying five 30 kg Internet of Things (IoT) nanosatellites for customer Kinéis – the first of which flew last June. A Rocket Lab Electron rocket, equipped with Curie upper stage, will carry satellites numbered 16 to 20 to a low-Earth orbit at 650 km altitude.

Liftoff was previously planned for Monday, Feb. 3, and is now rescheduled for Tuesday, Feb. 4 at 20:43 UTC. The first Electron to fly this year will leave pad LC-1A at Rocket Lab’s launch site on the Māhia Peninsula. This is an instantaneous launch window with additional opportunities at the same time over multiple days. Rocket Lab launched a record 16 missions last year, which it plans to exceed in 2025. Kinéis is backed by the French government’s space agency Centre National d’Études Spatiales (CNES) and international space solutions provider Collecte Localisation Satellites (CLS), to improve its global IoT connectivity.

Rocket Lab also announced a short-notice contract last week which it has signed with Ororatech for Electron to launch a wildfire detection mission in the coming weeks.
