NASA's MAVEN Reveals Stunning Discoveries of Red Planet Atmosphere: Exploring the Mysteries of Mars

Join us on a thrilling journey to Mars with the MAVEN Mission, the spacecraft that's unlocking the secrets of the Red Planet's atmosphere. In this video, we'll take you behind the scenes of one of NASA's most groundbreaking missions, as MAVEN orbits Mars and studies its atmospheric composition, climate history, and potential for life. You'll learn how MAVEN is helping us understand the evolution of Mars and its place in the Solar System, and why this mission is crucial for future exploration of the Red Planet. Don't miss out on this incredible adventure! In this video we discuss Nasa launched it’s mission “Mars Atmosphere and Volatile EvolutioN”. Often called Nasa’s Maven, Mission returned to normal science and relay operations on May 28, 2022, after recovering from an extended safe mode event. The spacecraft encountered problems in February with its Inertial Measurement Units or IMUs. The Nasa mission team successfully diagnosed the issue with these navigation instruments and developed a system for the spacecraft to navigate by the stars, which should allow for continued Maven mission operations through the next decade. This was a critical challenge facing the mission, but thanks to the work of the spacecraft and operations team, Maven will continue producing important science and operating as a relay for the surface assets through the end of the decade. Maven launched in November 2013 and entered orbit around Mars in September 2014. The mission’s goal is to explore the planet’s upper atmosphere, ionosphere, and interactions with the Sun and solar wind to explore the loss of the Martian atmosphere to space. Maven mission help in Understanding atmospheric loss gives scientists insight into the history of Mars' atmosphere and climate, liquid water, and planetary habitability. On Tuesday, Feb. 22, 2022, the team lost contact with the spacecraft after it performed a routine scheduled power cycle of IMU-1. IMUs are used to determine the spacecraft’s attitude in space by measuring its rate of rotation. The spacecraft entered “safe mode,” where it ceased all planned activities, including science and relay operations, and awaited further instructions from the ground. The team had already been working to develop all-stellar mode that’s a system to navigate by the stars without IMUs and to be implemented in October 2022 because IMU-1 had previously shown anomalies and IMU-2 was nearing the end of its lifespan. The development and switch to all-stellar mode is a standard practice when IMUs degrade on aging orbiters. This was a situation that no one initially anticipated, but the spacecraft performed as designed. By the time ended up on the backup computer, the spacecraft had been attempting to fix the problem with IMU-1 for about 78 minutes. We ended up on IMU-2, and the pressure was on to get the all-stellar mode ready as quickly as possible. In the following months, the spacecraft team at Lockheed Martin worked to expedite the development of software to enable all-stellar mode, since the predicted lifetime of IMU-2 would not last until October. On April 19, five months ahead of schedule, the spacecraft team completed development and uplinked the software patch to MAVEN. As soon as the code was uplinked, IMU-2 was powered off, preserving its remaining life for future spacecraft needs. Following the uplink, a series of tests were performed to verify the functionality of all-stellar mode, since the code had not previously been tested in flight. The spacecraft team rose to the challenge, working under intense pressure after the anomaly. MAVEN returned to nominal science and relay operations on Saturday, May 28, 2022, after successfully transitioning to full all-stellar navigation. MAVEN’s principal investigator is based at the University of California, Berkeley, while NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the MAVEN mission. Lockheed Martin Space built the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Pasadena, California, provides navigation and Deep Space Network support. The Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder is responsible for managing science operations and public outreach and communication. #thetimeline4001 #unitedstates #discovery #earth #megaprojects #science #mars #nasa #planet #space #spacecraft #usa #california #sciencefiction #scientificknowledge #sciencefacts #scienceexperiment #facts #geography #maven #mission #mars #atmosphere #nasa #spacecraft #exploration #redplanet #climate #unitedstates #potential #solarsystem #evolution #future exploration
