🚀 Second stage Engine Cut-Off confirmed!

The Falcon's second stage will now coast for about one hour. There will be a second and final engine burn before deployment of the three science missions on board!

[Rocinante]

🚀We're expecting the Falcon's second engine start in about 10 minutes. This burn will last only one minute, and is our last milestone before spacecraft deployments!

[Rocinante]

🚀🛰IMAP spacecraft separation confirmed!

One down, two to go! SWFO-L1 is up next!

[Rocinante]

🚀🛰SWFO-L1 spacecraft separation confirmed!

Only one more to go! Carruthers deployment coming up next.

[Rocinante]

🚀🛰Carruthers spacecraft separation confirmed!

That's three for three! All missions aboard today's launch have now been deployed.

[Rocinante]

Acquisition of Signal for all three spacecraft has been confirmed! IMAP, SWFO-L1, and Carruthers will orbit the Sun near Lagrange point 1, about one million miles from Earth.

IMAP launch and Falcon 9 first stage landing
  SciNews
A SpaceX Falcon 9 launch vehicle launched NASA's IMAP mission to interplanetary transfer orbit, along with NASA's Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Follow On-Lagrange 1 (SWFO-L1), from Launch Complex 39A (LC-39A) at Kennedy Space Center, Florida, on 24 September 2025, at 11:30 UTC (07:30 EDT). Following stage separation, Falcon 9's first stage (B1096) landed on the "Just Read the Instructions" droneship, stationed in the Atlantic Ocean, having previously supported the KF-01 launch. According to NASA, Interstellar Mapping and Acceleration Probe (IMAP) will map the boundaries of our heliosphere, study the Sun's activity and how the heliosphere boundary interacts with the local galactic neighbourhood beyond. NASA's Carruthers Geocorona Observatory is a small satellite that will observe Earth's outermost atmospheric layer, the exosphere. It will image the faint glow of ultraviolet light from this region, called the geocorona, to better understand how space weather impacts our planet. The SWFO-L1 spacecraft will monitor space weather and detect solar storms in advance, serving as an early warning beacon for potentially disruptive space weather, helping safeguard Earth's critical infrastructure and technological-dependent industries. The SWFO-L1 spacecraft is the first NOAA observatory designed specifically for and fully dedicated to continuous, operational space weather observations.

В Horizons JPL.NASA появилась возможность заказать эфемериды на IMAP. Ограничение - см. рис. Там в TDB, если в UTC - 24.09.2025  13:00:00 .. 24.10.2025  12:00:00 UTС
Попробовал по скорости найти коррекции - вроде были небольшие 26.09 .
Сейчас IMAP в 600 тыс км от Земли.

почему пишут "IMAP is no longer on orbit"?

[Rocinante]

почему пишут "IMAP is no longer on orbit"?

видимо, покинули околоземную орбиту и полетели в L₁ (которая относится уже к гелиоцентрической)?

[Олег]

почему пишут "IMAP is no longer on orbit"?

Может быть считают по сфере действия тяготения Земли ~ 929 тыс км. Сфера действия тяготения
5.10.2025 IMAP её покинул ( если по вышеуказанным данным от JPL ).
PS Хотя эксцентриситет оскулирующих геоцентрических ЭО чуть меньше 1. Но это уже формальность.

"Запущенный в 2025 году межзвездный картографический зонд НАСА (IMAP) издалека изучит границу гелиосферы, чтобы ответить на несколько вопросов о том, как эта граница защищает нашу солнечную систему. Созданный международной командой из 25 партнерских учреждений, IMAP оснащен 10 приборами, которые способны собирать данные об энергетически нейтральных атомах (ENAs), солнечного ветра, межзвездной пыли и многого другого, чтобы составить карту нашей гелиосферы. Миссия IMAP НАСА собирает данные о солнечном ветре, высокоэнергетических частицах и магнитных полях почти в режиме реального времени. Ученые могут использовать эти данные для исследования космической погоды, которая может нанести вред технологиям и астронавтам в космосе. (...) IMAP будет находиться в точке Лагранжа 1, или L1, примерно в 1 миллионе миль [1,6 миллиона км] от Земли по направлению к Солнцу. Гелиофизические миссии, такие как IMAP, получают большую выгоду от этой позиции, поскольку она обеспечивает беспрепятственный обзор солнечной активности". - Хорошо иллюстрированная пресс-подборка содержит дополнительную информацию о солнечном ветре и гелиосфере, миссии, космических аппаратах, приборах и многом другом.

NASA's IMAP Mission Reaches Its Destination
NASA's IMAP (Interstellar Mapping and Acceleration Probe) reached its destination at Lagrange point 1, or L1, approximately 1 million miles from Earth toward the Sun on Jan. 10.
The mission's operations team sent commands to the spacecraft on the morning of Jan. 9 to begin trajectory maneuvers to enter orbit at L1. Early on the morning of Jan. 10, the team confirmed the spacecraft had successfully entered its final L1 orbit, where it will stay for the duration of its mission.

^{On Jan. 10, flight controllers and spacecraft team members celebrated in the Mission Operations Center at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, as the Interstellar Mapping and Acceleration Probe (IMAP) completed the last of the maneuvers to position itself in orbit around the first Sun-Earth Lagrange point (L1).

From L1, IMAP will explore and map the very boundaries of our heliosphere — the protective bubble created by the solar wind that encapsulates our entire solar system — and study how the heliosphere interacts with the local galactic neighborhood beyond.
As a modern-day celestial cartographer, IMAP will also explore and chart the vast range of particles in interplanetary space, investigating two of the most important overarching issues in heliophysics, namely the energization of charged particles from the Sun and the interaction of the solar wind at its boundary with interstellar space. Additionally, IMAP's real-time observations of the solar wind and energetic particles provide critical data that can help mitigate adverse space weather effects for spacecraft and humans.

Lagrange point 1 provides IMAP a stable and clear 360-degree view of the heliosphere. This position also allows an unobstructed view of the Sun, which enables the spacecraft to give about a half hour's warning to voyaging astronauts and spacecraft near Earth of harmful radiation coming their way. The IMAP spacecraft launched on Sept. 24, 2025, and traveled to L1 together with the Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration's (NOAA) SWFO-L1 (Space Weather Follow On-Lagrange 1). There, it joins other spacecraft in orbit, such as NASA's Wind, ACE (Advanced Composition Explorer), and ESA (European Space Agency)/NASA's SOHO (Solar and Heliospheric Observatory). Data from IMAP's state-of-the-art instrumentation will greatly enhance the usefulness of data from these missions.
The mission is nearing completion of its commissioning phase and will begin its science mission on Feb. 1.
Principal investigator and Princeton University professor David McComas leads the IMAP mission, which has an international team of more than 20 partner institutions. Johns Hopkins' Applied Physics Laboratory (APL) in Laurel, Maryland, managed the development phase, built the spacecraft, and operates the mission, which is the fifth in NASA's Solar Terrestrial Probes Program portfolio. The Explorers and Heliophysics Projects Division at NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the Solar Terrestrial Probes Program for the agency's Heliophysics Division of NASA's Science Mission Directorate.
