NASA Works to Contact Scalable Small Satellite
Following a successful launch aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, NASA's Athena EPIC (Economical Payload Integration Cost) satellite was deployed on July 23. However, the small satellite has yet to send an expected beacon signal to help track its orbit.

Mission partners are collaborating at the NovaWurks data operations center in California to link with the satellite on each orbital pass. Teams are investigating received signals to positively confirm the location of Athena EPIC and its operational status. The team is also working to determine the cause of the initial missed signal acquisition and any factors that may have contributed to the delayed communication downlinks.

Athena EPIC is a pathfinder launch for a scalable satellite design to support future missions through partnerships. The U.S. Space Force and the National Oceanic and Atmospheric Administration (NOAA) are government partners for the test launch along with Athena EPIC's industry partner NovaWurks.

NASA's TRACERS Continues Recovery Efforts for One Satellite
Teams for NASA's TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission, which launched on July 23, are continuing recovery efforts for one satellite, called Space Vehicle 1 (SV1). The other satellite, called Space Vehicle 2 (SV2), remains in good health and has started the commissioning process.

An issue with the power subsystem on July 25 resulted in intermittent contacts and a loss of communication with SV1. Indications from earlier data suggest the spacecraft can only be active when it is receiving adequate power through its solar panels. Because of the spacecraft's current orientation, the next opportunity to reestablish contact and implement further recovery steps is later in August, when SV1's solar panels will receive more sunlight. The team is reviewing data collected from the spacecraft to diagnose and determine next steps. Following any contact with the spacecraft, the team will assess status and any impact to the mission's science goals.

The SV2 spacecraft is operational, and the commissioning for the spacecraft and instruments are progressing as expected. NASA anticipates completing commissioning for SV2 by the end of August.

The TRACERS mission launched to study magnetic reconnection and its effects in Earth's atmosphere. Magnetic reconnection occurs when activity from the Sun interacts with Earth's magnetic field. By understanding this process, scientists will be able to better understand and prepare for impacts of solar activity on Earth.

No significant updates on SV1 are expected for a few weeks. NASA will provide these updates at:

То же - SV1.
Но с ним есть связь когда СБ много на солнце. Следующий период - в конце августа.

Миссия TRACERS: как два новых спутника NASA помогут понять природу космической погоды

В июле 2025 года два спутника NASA, выведенные на орбиту ракетой SpaceX, начали работу по исследованию космической погоды. Зачем? Чтобы изучить явления, связанные с солнечной активностью. Они могут не только вызывать полярные сияния, которыми можно любоваться вечно, но и нарушать работу GPS, спутников и энергосетей. Миссия TRACERS поможет исследовать, как солнечный ветер взаимодействует с магнитосферой Земли и влияет на устойчивость современных технических систем — от навигации до связи и электроснабжения.

The Skykraft 4 satellites from the TRACERS launch have now been cataloged  in 590 km orbits; however the Space Force orbit data for SKYKRAFT 4B  (64896) are spurious - they show it in a geotransfer orbit that must  actually belong to an Ariane stage fragment

Спутники Skykraft 4 с момента запуска TRACERS в настоящее время каталогизированы на орбитах высотой 590 км; однако данные об орбите космических сил SKYKRAFT 4B (64896) являются ложными - они показывают его на геопереходной орбите, которая на самом деле должна принадлежать фрагменту ступени Ariane

НАСА восстановило связь с космическим аппаратом TRACERS и продолжает поиски [11 сентября]

Группа управления миссией восстановила связь с космическим аппаратом SV1 и работает над его возвращением и организацией научных исследований. Обновления будут опубликованы в блоге TRACERS по мере поступления новой информации.
