Supersonic + quiet = amazing effort NASA has some exciting news to share: on Jan. 12, 2024, they will reveal their quiet supersonic X-59 aircraft. This is a huge milestone that could change the way we travel by air and unlock new opportunities for discovery and innovation. But how did NASA achieve this feat of engineering, which has eluded many others who tried to overcome the loud sonic boom that comes with supersonic flight? The secret is multiphysics simulation software, which is essential for understanding and minimizing the noise of supersonic engines. Besides the sonic boom, noise during take-off and landing also needs to be considered when creating quieter aircraft.

𝐔𝐧𝐢𝐭 𝐂𝐨𝐧𝐯𝐞𝐫𝐬𝐢𝐨𝐧 𝐄𝐫𝐫𝐨𝐫𝐬: 𝐀 𝐂𝐨𝐬𝐭𝐥𝐲 𝐎𝐯𝐞𝐫𝐬𝐢𝐠𝐡𝐭 🚀🔧 𝐇𝐚𝐯𝐞 𝐲𝐨𝐮 𝐞𝐯𝐞𝐫 𝐡𝐞𝐚𝐫𝐝 𝐨𝐟 𝐚 𝐬𝐩𝐚𝐜𝐞𝐜𝐫𝐚𝐟𝐭 𝐛𝐞𝐢𝐧𝐠 𝐥𝐨𝐬𝐭 𝐝𝐮𝐞 𝐭𝐨 𝐚 𝐬𝐢𝐦𝐩𝐥𝐞 𝐦𝐢𝐬𝐭𝐚𝐤𝐞? It's true! In 1999, NASA's Mars Climate Orbiter was destroyed because of a unit conversion error. Engineers had used English units (pounds-force-seconds) for some calculations, while others were in metric units (newtons-seconds). This discrepancy led to incorrect thrust calculations, causing the spacecraft to enter the Martian atmosphere at the wrong angle and burn up. This incident highlights the critical importance of *unit consistency* in engineering and scientific work. A seemingly small oversight can have catastrophic consequences. 𝐊𝐞𝐲 𝐭𝐚𝐤𝐞𝐚𝐰𝐚𝐲𝐬: 𝐀𝐥𝐰𝐚𝐲𝐬 𝐝𝐨𝐮𝐛𝐥𝐞-𝐜𝐡𝐞𝐜𝐤 𝐮𝐧𝐢𝐭𝐬: Ensure that all measurements and calculations are using the same unit system. 🔍 𝐔𝐬𝐞 𝐮𝐧𝐢𝐭 𝐜𝐨𝐧𝐯𝐞𝐫𝐬𝐢𝐨𝐧 𝐭𝐨𝐨𝐥𝐬: These can help prevent errors and simplify the process. 🛠️ 𝐃𝐨𝐜𝐮𝐦𝐞𝐧𝐭 𝐮𝐧𝐢𝐭𝐬: Clearly indicate the units used in your work to avoid confusion. 📑 By following these pointers, we can help prevent costly and potentially dangerous mistakes.

That moment you internalize the fact that NASA engineers are successfully debugging hardware issues + running maintenance jobs on an interstellar craft that is no longer in our solar system -- 15 billion miles away. 🤯🚀 --- "On May 19, the mission team executed the second step of that repair process and beamed a command to the spacecraft to begin returning science data. Two of the four science instruments returned to their normal operating modes immediately. Two other instruments required some additional work, but now, all four are returning usable science data." https://lnkd.in/eVreGTEa #spaceexploration #nasa #spacescience

🌎 🚀ISRO's SSLV-D3 Completes Final Development Flight! In a major milestone, ISRO's SSLV-D3 rocket successfully lifted off from the Satish Dhawan Space Centre at 9:17 AM, injecting the EOS-08 satellite into a precise 475 km circular orbit just 17 minutes later. This marks the third and final developmental flight of the SSLV, with ISRO Chairman S. Somanath confirming the success and announcing the completion of SSLV's development. The SSLV technology will now be transferred to industry for serial production and future launches. The EOS-08 satellite is a first-of-its-kind mission, based on ISRO's Microsat/IMS-1 bus. It carries advanced payloads for IR observation, GNSS-R, and a SiC UV dosimeter. Key technological advancements include an Integrated Avionics System, Flexible Solar Panels, a Phased Array Antenna, Micro-Dual Gimbal Antenna, and an embedded battery, making it a pioneering effort in satellite technology. #isro #isro #isromissions #nasa #NASA #solarsystem #spacecraft #rocketry #rocketscience #rocket #space #science #news #spacenews #astronomy #astrophysics

On October 13, 2024, SpaceX launched Starship, the most powerful rocket ever built, on its fifth test flight. The Super Heavy booster successfully returned to the launchpad, showing improvements over the previous June test, where severe wear and tear had caused issues. This time, enhanced heat shields protected the spacecraft better during reentry. The successful catch of the booster by the "Chopsticks" arms was a key achievement, further pushing the reusability of Starship for future moon and Mars missions. ___________________________________________ #spacexstarship #spacexlaunch #raptorengine #spacex #space #spacetech #elonmusk #futureofspace #marsmission #artemisprogram #rocketlaunch #spaceexploration #aerospace #nasa #innovation #superheavy #technology #moonmission #reusablerockets #engineering #science #spacetech #spacexstarship #spacexlaunch #raptorengine #spacex #space #news

ADITHYA L1 accomplishment:Halo-Orbit Insertion (HOI) of its solar observatory spacecraft, Aditya-L1 was accomplished at 16.00 Hrs (approx) on January 6, 2024 (IST). The final phase of the maneuver involved firing of control engines for a short duration. The orbit of Aditya-L1 spacecraft is a periodic Halo orbit which is located roughly 1.5 million km from earth on the continuously moving Sun – Earth line with an orbital period of about 177.86 earth days. This Halo orbit is a periodic, three-dimensional orbit at L1 involving Sun, Earth and a spacecraft. This specific halo orbit is selected to ensure a mission lifetime of 5 years, minimising station-keeping manoeuvres and thus fuel consumption and ensuring a continuous, unobstructed view of sun. #isromissions #india #nasa #isroindia #space #science #astronomy #satellite #isroscientists #facts #astrophysics #spaceexploration  #Spacefacts #pegasusaerospacesystems Follow us & Learn Daily Pegasus Aerospace System and Engineering Services
