Some neat clips of the FLEX rover being driven and the hardware prototypes they have. The video seems to mostly serve as a hiring call though.

A Chinese commercial launch firm launched its first upgraded Kuaizhou-1A rocket late Tuesday, adding to the country’s growing light-lift launch options.

The enhanced Kuaizhou-1A rocket lifted off at 11:46 p.m. Eastern, Dec. 3 (0546 UTC, Dec. 4) from Xichang Satellite Launch Center, southwest China. The solid rocket climbed rapidly into blue skies above the spaceport. Commercial space launch firm Expace announced launch success once it inserted its single satellite payload into its preset orbit.

The payload was announced to be Haishao-1, also referred to as CAS Satellite-8. It is described as a synthetic aperture radar (SAR) remote sensing satellite. Haishao-1 can perform on-board imaging and extract marine dynamic information, offering broad application prospects.

The upgraded Kuaizhou-1A appears to have extended first and second stages, and a payload fairing extended from 1.4 to 1.8 meters. Its payload capacity to low Earth orbit (LEO) is increased from 300 kilograms to 450 kg. Its sun-synchronous orbit (SSO) capacity to 700 km altitude is increased from 200 kg to over 300 kg.

A Long March 3B rocket lifted off at 12:56 a.m. Eastern (0556 UTC) Dec. 3 from the Xichang Satellite Launch Center, southwest China. The China Aerospace Science and Technology Corporation (CASC) announced launch success, revealing the previously undisclosed payload to be communication technology experiment Satellite-13, or Tongxin Jishu Shiyan-13 (TJS-13). The satellite is expected to be in geosynchronous transfer orbit.

The TJS-13 satellite will be used for satellite communication, radio and television, data transmission and other services, and will also carry out related technology tests, according to Chinese state media. However, the lack of specific details surrounding the TJS-13 satellite, consistent with earlier TJS missions, suggests potential dual-use or military-related capabilities

The launch was, notably, the 100th of the workhorse Long March 3B. The rocket has performed 96 successful launches with two failures and two partial failures. The first launch, in February 1996 carrying Intelsat 708, infamously saw the rocket veer off course shortly after clearing the tower and impacting a nearby village.

No word about their plans, but a video on the steps taken to ruggedise a cube sat for 10k·g acceleration. Seems like they're still doing something.

China launched its first Long March 12 rocket Saturday, marking an advance in its crewed moon plans and the debut of a new spaceport that will boost the country’s access to space.

The two-stage, 62-meter-tall Long March 12 lifted off at 9:25 a.m. Eastern (1425 UTC) Nov. 30 from the Wenchang Commercial Space Launch Site. The rocket climbed into the night sky above the coastal spaceport, with amateur live streams from the area capturing the event.

The kerosene-fueled Long March 12 is China’s first 3.8-meter-diameter launch vehicle. It can carry a payload of 12,000 kilograms to low Earth orbit (LEO), and 6,000 kg to sun-synchronous orbit (SSO), according to SAST. The new rocket could play a role in the construction of China’s planned LEO megaconstellations.

The launch was the first flight use of the YF-100K engine, with the Long March 12 using four YF-100K engines on its first stage. The YF-100K is an uprated version of the YF-100 kerosene-liquid oxygen engines that power China’s new-generation liquid propellant rockets. These newer rockets include the Long March 5, 6, 7 and 8.

The YF-100K notably will power the first stages of the Long March 10 rocket. That launcher is intended to send China’s astronauts to the moon before the end of the decade. A reusable version of the engine, the YF-100N, is also being developed.

A Soyuz-2 rocket lifted off from Vostochny Cosmodrome on Nov. 30, 2023, carrying the Kondor FKA No. 2 radar satellite. It was the fifth mission to orbit an all-weather, day-and-night imaging spacecraft from the Kondor family, counting one previous FKA variant, one classified military version, known as Neitron, and two original Kondors.

The Kondor-FKA is a small civilian radar Earth observation satellite designed by NPO Mashinostroyeniya as a civilian counterpart to the Kondor-E satellite.

The Kondor satellite features a S-band synthetic aperture radar (SAR), which can conduct both continous swath surweys or detailed spot surveys. The swath width is 10 km. Ground resolution is 1-2 m in spotlight mode, 1-3 m in stripmap mode and 5-30 m in ScanSAR mode.

When you compare SpaceX to the world's other space enterprises, it's probably easier to list the things SpaceX hasn't done instead of reciting all of the company's achievements.

One of these is the launch of nuclear materials. SpaceX has launched a handful of planetary science missions for NASA, but these spacecraft have all used solar arrays to generate electricity. In this century, NASA's probes relying on nuclear power have all flown on rockets built by United Launch Alliance (ULA), a 50-50 joint venture between Boeing and Lockheed Martin.

This is about to change with a $256.6 million contract NASA awarded to SpaceX on Monday. The contract covers launch services and related costs for SpaceX to launch Dragonfly, a rotorcraft designed to explore the alien environment of Saturn's largest moon, Titan.

Dragonfly's power source is a radioisotope thermoelectric generator (RTG), which generates electricity from the heat put out by the radioactive decay of plutonium-238. These plutonium-fueled generators have flown on many previous space missions, including NASA's Perseverance and Curiosity rovers on Mars, the New Horizons spacecraft that beamed back the first up-close views of Pluto, and the long-lived Voyager probes exploring interstellar space.

All of these missions were launched on rockets that have either retired or are nearing retirement: the Atlas V, the Titan, and the space shuttle, to name a few.
