First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 07:30 – 19:30 UTC. The most common times to find a crew member making casual periods are about one hour after waking up and about an hour before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is sometimes active. Check the status at https://www.ariss.org/ or http://www.issfanclub.eu to see if the packet system is active or not. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

On board was the Meteor-M2-4 weather spacecraft, a notable addition to the Meteor-M series, alongside several secondary payloads, including an Iranian micro-satellite dedicated to Earth observation. Developed by the Moscow-based VNIIEM Corporation, Meteor-M2-4, weighing nearly three tons, boasts advanced instruments designed for comprehensive monitoring of global weather patterns, the ozone layer, ocean surface temperature, and ice conditions. Recognized for its military applications by the Russian space agency, Roscosmos, this mission marked a significant stride in space exploration. Meteor-M2-4 encountered delays in its journey, originally slated for a December 26, 2023 launch. However, due to multiple rescheduling, the liftoff finally took place on February 29, 2024. The spacecraft, delivered to the launch site on December 28, 2023, underwent meticulous preparations, including fueling and integration with the launch vehicle, ultimately culminating in a successful liftoff. Meteor-M 2-4 Satellite / Secondary Payloads Encapsulated in Payload Fairing [Credit: Roscosmos] Following the standard ascent profile for Meteor satellites, the launch trajectory headed northwest over eastern Russia, reaching a near-polar orbit with an inclination of approximately 98.57 degrees. The fairing protecting the payload separated during the second stage operation, with subsequent stage separations carefully planned for safe impact zones in the Amur Region and the Sakha Republic. The Fregat upper stage took charge of the final payload deployment, executing precise maneuvers over the Arctic and Antarctica. Approximately 59 minutes and 46 seconds after liftoff, the Meteor-M2-4 satellite was successfully released, accomplishing its primary mission. The Fregat then proceeded to deploy the secondary payloads into their designated orbits. Meteor M2-4 Image Decoded Using a Raspberry Pi 5 and SatDump by N5ZKK [Credit: David Trolinger] The Russian Meteor M2-4 satellite commenced transmitting weather images within the first day in orbit. Known for their accessibility to amateur users, Meteor M satellites operate around 137 MHz, making them receivable with a RTL-SDR dongle and suitable satellite antennas. The satellite also transmits in the L-band, enabling reception with a 60cm or larger dish and motorized or hand tracking. Unlike previous satellites in the series, M2-4 experienced a smooth launch and deployment, with reports indicating excellent signal strength and clear image reception in both VHF and L-band frequencies. Two-Line Elements (TLE's) and the SatDump decoding software (https://github.com/SatDump/SatDump) have been updated to support Meteor M2-4, simplifying access for enthusiasts through Github updates. Space historian Jonathan McDowell shared valuable insights into the flight, detailing each Fregat maneuver and its impact on the satellite cluster. While the majority of the secondary payloads adhered to the expected orbits, anomalies in the deployment of some SITRO satellites prompted further investigation. The launch of Meteor-M2-4 and its accompanying payloads stands as a noteworthy accomplishment for Russia's space program, contributing significantly to global endeavors in weather monitoring, Earth observation, and satellite technology development.

See the interview at Michael's YouTube channel: https://www.youtube.com/watch?v=_sdW_mhbUew + Recently Completed Contacts “IES Pedro Simón” Abril High School, Alcaraz, Spain, telebridge via K6DUE The ISS callsign was NA1SS The scheduled crewmember was Loral O’Hara KI5TOM The ARISS mentor was IKØUSO Contact successful: Mon 2024-03-04 11:21:02 UTC Watch for Livestream at https://www.youtube.com/watch?v=9Xgk4YZT5w4 + Upcoming Contacts No upcoming contacts scheduled As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down). If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know. The Service Module radio is currently misconfigured. SSTV radio is currently stowed. Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html [ANS thanks Charlie Sufana, AJ9N, one of the ARISS operation team mentors for the above information] Upcoming Satellite Operations PJ2, CURACAO: Andreas, DK5ON, is going to pay a visit to Curacao from March 11 to 27.

The coverage will commence with a change-of-command ceremony at 11:55 a.m. EDT. Astronauts Jasmin Moghbeli, Andreas Mogensen, Satoshi Furukawa, and Konstantin Borisov will conclude their nearly six-month science mission. Weather permitting, the SpaceX Dragon spacecraft is set to undock on March 11 at 11:05 a.m., with splashdown targeted for as early as 5:35 a.m. on March 12 off the Florida coast. The live coverage will be available on NASA+, NASA Television, the NASA app, and the agency's website, featuring farewell remarks, hatch closure, undocking, and splashdown events, as well as a media teleconference on March 12 with key participants. (ANS thanks NASA for the above information) + SpaceX is aiming for the third test flight of its Starship rocket on March 14, as announced through a post on the X platform. The Starship vehicle comprises a stainless-steel reusable upper stage, also known as Starship, and a Super Heavy first-stage booster, standing over 400 feet tall together. A recent critical fueling test at the Starbase facility in Texas involved pumping over 10 million pounds of liquid methane and liquid oxygen into the rocket. The upcoming launch follows two previous test flights in April 2023 and November 2023, where Starship faced issues like failure to separate from the first-stage booster and a subsequent explosion of the Super Heavy. After the second test, the FAA identified seventeen corrective actions, all of which SpaceX claims to have completed, addressing issues related to leak reduction, fire protection, and propellant vent operations. The Starship and Super Heavy, designed for full reusability, are pivotal for NASA's Artemis 3 mission to land astronauts on the moon by 2026. (ANS thanks Brett Tingley, Space.com, for the above information) + NASA has identified a growing air leak on the International Space Station (ISS) located at the end of the Russian service module. The leak, situated in Russia's Zvezda service module, initially released one pound of air per day but accelerated to over two pounds daily in early February. Despite the increased rate, NASA assures that it does not currently jeopardize the safety of the ISS crew or impact the station's operations. Collaboration between the United States, Russia, Europe, Japan, and Canada is underway to address the situation. Roscosmos, the Russian space agency, confirms ongoing monitoring and asserts that there is no immediate threat to the crew or the station itself. The leak is in a three-foot-long area and has prompted precautionary measures, including sealing off the affected vestibule to mitigate further air loss from the rest of the space station. (ANS thanks Will Sullivan, Smithsonian Magazine, for the above information) + The inaugural components for Europe's new Ariane 6 rocket have reached the port of Pariacabo in Kourou, French Guiana, transported by the container ship, Canopée. Manufactured across Europe, the central core arrived on Canopée, which uses sails to reduce emissions and save up to 30% on fuel during its 10-day, 7,000 km journey. The rocket's stages were produced in various European locations, with the main engine and stage integrated in Les Mureaux, France, and the upper stage and insulation in Bremen, Germany. Following transport, the components were offloaded and taken to the Ariane 6 assembly building, a few kilometers away, where they will undergo integration before liftoff. The boosters, already at Europe's Spaceport, are P120C solid propulsion boosters similar to those used for the Vega-C rocket. The central core will be assembled horizontally and then transported to the launchpad, where it will be erected, followed by the addition of boosters and the upper stage, with the goal of a summer launch for Flight Model-1.
