Atomos Area's first orbit mission is a take a look at by fireplace | TechCrunch https://lnkd.in/d-ez325H Few missions extra clearly embody the maxim “house is difficult” than Atomos Area's first demonstration mission, which the corporate has managed to drag again from the brink of catastrophe, greater than as soon as. That demonstration mission, referred to as Mission-1, was launched into orbit on a SpaceX Falcon 9 rocket on March 4. The mission's targets are formidable to a fault: The 2 spacecraft – an orbital switch car referred to as Quark-LITE and a goal car referred to as Gluon – will ultimately reveal extraordinarily advanced maneuvers together with rendezvous, docking, orbital switch and refueling in orbit. The corporate has confronted two essential issues associated to communications and the rotation velocity of the spacecraft, and has (largely) solved each issues, regardless of huge limitations, rare information packets, and very restricted bandwidth. (So restricted, actually, that the staff needed to restrict updates to its flight software program to a textual content string of simply 145 characters.) “It's been relentless,” Atomos CEO and co-founder Vanessa Clark advised TechCrunch. The corporate's chief working officer and co-founder, William Kowalski, agreed. “What makes it so tough, even in our scenario, is that we try to extrapolate the state of a really sophisticated system from about 100 bytes of information,” he stated. “It's so much, you're making assumptions about what's driving this, understanding that a few of these assumptions may lead you down a path you'll by no means recuperate from.” The issues started simply hours after the 2 spacecraft, that are docked, deployed from the Falcon 9 higher stage. The deployment was nominal and Atomos acquired its first ping from the spacecraft seven minutes after deployment. The ambiance was celebratory. However then 40 minutes handed earlier than the corporate acquired the subsequent ping. Then eight hours. Atomos anticipated information packets each two minutes. “The worst (day) was Monday after we pitched, that night time,” Kowalski stated. “It was 11 at night time, it was the chief engineer and I… and we haven't heard something, and we have been simply considering, did we fail? Did they die? We tried it and it simply didn't work. “That was actually a punch within the intestine.” Mission controllers solely recognized the basis trigger 24 to 48 hours after deployment, they usually did so with the assistance of one other firm with property in orbit. After pulling some strings, they have been capable of communicate on the telephone with the chief methods engineer at satellite tv for pc communications firm Iridium. The spacecraft used third-party modems that took benefit of Iridium's

Queqiao-2: China's Lunar Relay Satellite Queqiao-2, named after a bridge in a Chinese fairy tale, is a critical piece of the Chinese Lunar Exploration Program (CLEP) plan to have a permanent base on the moon. Positioned in lunar orbit, the satellite ensures reliable and stable communication for all Chinese lunar missions, both robotic and human, providing a real-time 'bridge' with Earth, enabling remote control, telemetry, and the transmission of scientific data. Launched on March 20, 2023, by a Long March 8 rocket from Wenchang, China, Queqiao-2 is a larger version of its predecessor, the first Queqiao relay satellite. With a planned lifetime of over 8 years, the 1200 kg satellite, based on the CAST 2000 bus, is equipped with state-of-the-art communication technology, including a 4.2-meter diameter parabolic dish antenna for communication with landed missions in X band and UHF, and a 0.6-meter parabolic antenna for communication with ground stations in the S and Ka bands. In its 200 km by 16,000 km, highly-elliptical “frozen” orbit, Queqiao-2 will have simultaneous direct line-of-sight with both ground stations on Earth and the lunar far side for large portions of a 24-hour-period orbit. This frozen orbit is intended to be very stable and requiring little maintenance, boosting mission longevity. Queqiao-2 relay satellite is enabling communication with the Chang'e 6 sample-return probe, which landed on the far side of the moon. https://lnkd.in/dq9HTw-W In addition to its vital communication role, Queqiao-2 carries three science payloads: an Extreme Ultraviolet Camera (EUC), a Grid-based Energetic Neutral Atom imager (GENA), and a very long baseline interferometer, the Lunar Orbit VLBI EXperiment (LOVEX). These instruments will contribute to our understanding of the lunar environment and the universe beyond. Looking ahead, CLEP plans to launch powerful new Long March 10 rockets capable of lifting 27 tonnes into trans-lunar injection trajectories, and develop spacecraft for human transportation. The goal is ambitious: to bring the first Chinese astronauts to the Moon by 2030 and establish a permanent lunar base with scientific research capabilities and long-term habitability.

NASA’s TBIRD (TeraByte InfraRed Delivery) demonstration and its host spacecraft — the PTD-3 (Pathfinder Technology Demonstrator-3) — have completed their technology demonstration. The TBIRD payload spent the past two years breaking world records for the fastest satellite downlink from space using laser communications. NASA’s PTD series leverages a common commercial spacecraft to provide a robust platform for effective testing of technologies with minimal redesign in between launches. After launch in May 2022 on the SpaceX Transporter 5 mission, the PTD-3 spacecraft entered low-Earth orbit and shortly after TBIRD began sending laser communications signals to an optical ground station in Table Mountain, California. TBIRD’s two-year demonstration showcased the viability of laser communications. Most NASA missions rely on radio frequency communication systems, however, laser communications use infrared light and can pack significantly more data in a single communications link. This technology is ideal for science and exploration missions that need large data transmissions. In 2023, TBIRD continuously broke its own records, reaching its peak in June when it transmitted 4.8 terabytes of error-free data — equivalent to about 2,400 hours of high-definition video — in five minutes at 200 gigabits per second in a single pass. The TBIRD payload was one of many laser communications demonstrations. NASA’s SCaN (Space Communications and Navigation) program is maturing this technology to demonstrate the impact laser communications can have for bringing more science and exploration data home. The next demonstration will be on the Artemis II mission. In addition to breaking a world record, this mission demonstrated cost-effective design and extremely low size, weight, and power requirements — both on the PTD-3 spacecraft and within the TBIRD payload. The tissue-box-sized payload contained two commercial telecommunication modems that the TBIRD team modified for the extreme environment of space. The PTD-3/TBIRD system also overcame one of the major challenges associated with laser communications: making the narrow beam laser link connection while moving at orbital speeds while being buffeted by atmospheric drag. The PTD-3 spacecraft’s precision “body pointing” and stability enabled the TBIRD payload to make its record-breaking achievement while moving as fast as 17,000 mph through space. The spacecraft set a record for the highest accuracy pointing ever achieved by a NASA CubeSat without any moving mechanisms or propulsion systems. #SCaN #NASA #TBIRD NASA’s Laser Communications Roadmap – proving the technology’s validity in a variety of environments.

Roscosmos approves design of Russia’s future orbital station The station’s deployment, as it was previously reported, is due between 2027 and 2032 MOSCOW/ Roscosmos has approved the preliminary design of a future Russian orbital station (ROS). "The preliminary design of Russia’s orbital station has earned approval from the state corporation Roscosmos," the statement reads. Roscosmos and the main contractors are in the process of concluding government contracts for building the station. Roscosmos recalled that the proposed orbital outpost would serve as the base of Russia’s national space program when the International Space Station (ISS) ended its life cycle. The station’s core module will have six docking ports for accommodating add-on modules. Each of the station's modules will be replaceable, if necessary, so the ROS’s service life is likely to last decades. The station will stay in a polar orbit with an inclination of up to 97 degrees. "This will give an overview of the Earth’s entire surface, including the strategically important Northern Sea Route. Currently, the cosmonauts on the ISS can see about 60% of the Earth's surface, of which only a tiny 10%-fraction is Russian territory," Roscosmos said, adding that the polar orbit would ensure guaranteed stable communication with mission control. Heavy-duty power generating units, Roscosmos said, are one of the ROS’s major strengths. They will allow for testing and polishing to perfection the required equipment, radars and high-power antenna systems. The gyroscopic systems will keep the station in its orbit without using the engines, thus significantly reducing fuel consumption. The station’s deployment, as it was previously reported, is due between 2027 and 2032. "First, the research, power supply and airlock modules will be put in space. The base module will follow to assume the station's control functions. Other add-on modules will join the orbiter later," Roscosmos. The corporation recalled that unlike the ISS, the new station will be able to stay in operation without a crew on board. Russian Orbital Station’s profile The idea of creating Russia's own orbital station hit the headlines in April 2021. Last October, Roscosmos CEO Yuri Borisov said that the project’s costs were estimated at 609 billion rubles (roughly $6.6 billion at the current rate of exchange) until 2032, of which amount 150 billion rubles is to be spent in the first three years. The project is open to international cooperation: African and BRICS countries have been invited to participate. #business #finance #financialservices

Progress MS-28 cargo spacecraft with fruit, scientific equipment, other cargo docks ISS The cargo spacecraft docked the station in automatic mode MOSCOW, August 17/ The Progress MS-28 cargo spacecraft, which was launched from the Baikonur spaceport on Thursday, has docked the Zvezda module of the Russian segment of the International Space Station (ISS), according to a Roscosmos broadcast. The cargo spacecraft docked the station in automatic mode. The process was controlled by specialists of the Mission Control Center and by Roscosmos cosmonauts Oleg Kononenko (TASS special correspondent), Nikolay Chub and Alexander Grebenkin. The Progress MS-28 cargo spacecraft delivered 2,621 kilograms of cargo to the ISS, including 950 kilograms of fuel, 420 liters of drinking water, 50 kilograms of compressed nitrogen in cylinders, as well as about 1,201 kilograms of various equipment and materials in the cargo hold: food for the crew, clothing items and kits for scientific experiments. In particular, Progress arrived with the SPIN-X1-MVN X-ray spectrometer, which the cosmonauts will install outside the Zvezda module during extravehicular activities. It will allow scientists to periodically conduct an almost complete survey of the celestial sphere in the X-ray range. In addition, the spacecraft also brought stowages for new scientific experiments. Andrey Vedernikov, a senior research fellow responsible for nutrition, told TASS that fresh oranges, grapefruits and onions arrived on the cargo ship to the station. The Progress MS-28 spacecraft also delivered coffee with and without sugar to the cosmonauts. #business #finance #financialservices

Teams from across ESA and industry have worked continuously over the past four months to overcome a glitch that prevented BepiColombo’s thrusters from operating at full power. The ESA/JAXA mission is still on track, with a new trajectory that will take it just 165 km from Mercury’s surface on Wednesday. Taking BepiColombo closer to Mercury than it’s ever been before, this flyby will reduce the spacecraft’s speed and change its direction. It also gives us the opportunity to snap images and fine-tune science instrument operations at Mercury before the main mission begins. Closest approach is scheduled for 23:48 CEST (21:48 UTC) on 4 September. BepiColombo launched into space in October 2018 and is making use of nine planetary flybys: one at Earth, two at Venus, and six at Mercury, to help steer itself into orbit around Mercury. Once in orbit, the main science phase of the mission can begin. The upcoming flyby will be the fourth at Mercury. Whilst it was always in the schedule, BepiColombo will get around 35 km closer to Mercury than originally planned, due to a new route devised by ESA’s flight dynamics team. BepiColombo is unique in that it comprises two science orbiters that will circle Mercury – ESA’s Mercury Planetary Orbiter and the Japan Aerospace Exploration Agency’s (JAXA) Mercury Magnetospheric Orbiter. The two are carried together to the mysterious planet by the Mercury Transfer Module (MTM). In April 2024, BepiColombo started experiencing an issue that prevented MTM’s electric thrusters from operating at full power. Engineers identified unexpected electric currents between MTM’s solar array and the unit responsible for extracting power and distributing it to the rest of the spacecraft. Onboard data imply that this is resulting in less power available for electric propulsion. BepiColombo’s main science camera is shielded until the ESA and JAXA orbiters separate, but during flybys images are taken by the three monitoring cameras (M-CAMs) on the Mercury Transfer Module. The cameras provide black-and-white 1024x1024 pixel snapshots. Their images of Mercury are a bonus: the cameras were actually designed to monitor the spacecraft's solar array, antenna and magnetometer boom, especially in the challenging period after launch. As BepiColombo passes Mercury, well-lit images will begin to be taken by M-CAM 2 and M-CAM 3 two minutes after closest approach, when BepiColombo is around 200 km from Mercury’s surface. M-CAM 1 will have a beautiful view of Mercury receding into the distance. #ESA #JAXA #Mercury #BepiColombo
