On this day in space! Nov. 7, 1992: NASA launches Mars Global Surveyor, its 1st Mars mission in 20 years at the time, to map the Red Planet like never before

AI-summarised brief · reviewed before publication

On 7 November 1996 NASA launched the Mars Global Surveyor (MGS) aboard a Delta II, marking the agency’s first Mars mission in nearly two decades since Viking. The orbiter served both as a scientific platform and a communications relay for later rovers, transmitting data from Sojourner, Spirit and Opportunity to Earth. MGS mapped the planet’s surface, discovering gullies that appear to have been carved by intermittent water flow and detecting hematite deposits—an iron oxide that forms in watery environments. Observations of the south polar region suggested possible climate change. Over its nine‑year operational span the spacecraft returned more than 240,000 images before a battery‑exposure mishap caused permanent loss of power in November 2006. Its longevity exceeded the mission’s five‑year design goal.

💡 Why It Matters

· By proving that a long‑duration orbiter could also act as a data highway, MGS enabled the rapid deployment of multiple rovers, accelerating the search for past water on Mars.

Send your name to Saturn’s moon Titan with NASA’s upcoming Dragonfly mission

NASA’s Dragonfly mission, a nuclear‑powered, SUV‑sized rotorcraft, is slated for launch in 2028 to explore Saturn’s moon Titan, with arrival expected in 2034. The agency has opened a public‑name‑submission portal, allowing anyone to have their name etched onto a chip aboard the craft if submitted by Jan. 15, 2027. Once on Titan, Dragonfly will hop between sites spaced miles apart, conducting up to one flight every 16 Earth days over a 3.3‑year surface campaign. It will investigate dunes, the Selk impact crater, and other geologic locales, sampling material to study pre‑biotic chemistry, past habitability, and potential biosignatures. Dragonfly follows the 2005 Huygens lander and builds on the legacy of NASA’s Ingenuity helicopter, marking the first multi‑site aerial exploration of an outer‑solar‑system world.

💡 By letting the public embed their names on an interplanetary probe, NASA turns a scientific venture into a shared cultural milestone, deepening public engagement with the search for life's building blocks beyond Earth.

‘I think we will prevail’: NASA chief Jared Isaacman on Artemis, China…

NASA Administrator Jared Isaacman told Space.com that the agency aims to launch “big rockets” at least once a year to sustain the Artemis program and keep pace with China’s accelerating lunar ambitions. He said the success of Artemis II in April 2026 proves the United States is on a more achievable path to the lunar surface, and that the next launch in 2027 will be Artemis III, a low‑Earth‑orbit test of Orion docking with private landers from SpaceX and Blue Origin. Isaacman emphasized that annual SLS flights are the minimum needed to maintain deep‑space human‑flight capability and to prepare for Artemis IV’s crewed moon landing targeted for 2028. He warned that falling behind China could have far‑reaching geopolitical and technological consequences.

💡 A yearly cadence of heavy‑lift launches will lock the U.S. into a sustained lunar presence, preventing China from gaining a decisive strategic edge in space.

Northern lights could reach New York and Idaho this weekend as speedy…

A massive coronal hole on the Sun is sending a high‑speed solar wind toward Earth, creating a minor (G1) geomagnetic storm from Nov. 6‑8 and a possible moderate (G2) storm on Nov. 7‑8, NOAA’s Space Weather Prediction Center reports. The wind, traveling 342‑404 mph, could trigger auroras visible as far south as New York and Idaho if G2 conditions materialize. The U.K. Met Office forecasts speeds up to 650 km/h, and the event offers a rare opportunity for widespread aurora viewing across the U.S.

💡 The potential reach of the auroras into populous regions could spark widespread public interest in space weather and highlight the need for accurate forecasting tools.

SpaceX launches mystery mission for US Space Force in gorgeous sunset liftoff…

SpaceX launched a classified U.S. Space Force mission, USSF‑432, from Vandenberg Space Force Base on Nov. 6 at 7:48 p.m. EST. A Falcon 9 lifted off as the sun set, and its first stage returned to land on the droneship “Of Course I Still Love You,” marking the booster’s eighth flight (serial 1095). The webcast was cut ten minutes after liftoff, and the upper stage continued toward a likely low‑Earth‑orbit payload. Analysts suspect the payload consists of secret Starshield satellites supporting the Space Based Sensing and Targeting portfolio, given the launch’s trajectory and similarity to prior Starlink Group 15 missions. USSF‑432 is the 119th Falcon 9 launch of 2026 and the 14th national‑security flight this year, underscoring SpaceX’s growing role in U.S. defense space operations.

💡 By fielding covert Starshield satellites, SpaceX is cementing its position as the primary launch provider for U.S. military space assets, accelerating the Pentagon’s shift toward responsive, low‑orbit sensing capabilities.

Giant exoplanet emerges from the dark when the James Webb Space Telescope…

A team of astronomers used a new image‑processing technique called FLIP to remove residual starlight from James Webb Space Telescope data, revealing the previously hidden exoplanet 51 Eridani b. The method creates a digital twin of the telescope to model and subtract minute mirror vibrations that scatter starlight. Applying FLIP to JWST observations of 51 Eridani and HIP 65426 improved planet detection by up to fifteen times, allowing the planet to emerge from data collected two years earlier. The study demonstrates a powerful tool for uncovering faint exoplanets in existing datasets.

💡 By unlocking data that was previously unusable, FLIP expands the reach of JWST and future missions, enabling the discovery of planets that could reshape our understanding of planetary system diversity.

What’s that bright ‘star’ in the early morning sky? It’s not a…

Early morning commuters have spotted a bright, star‑like object in the east‑southeast sky, which is actually Venus. After its inferior conjunction on Oct. 24, Venus moved from the evening to the morning sky, now rising more than 90 minutes before sunrise. It will rise three minutes earlier each day, peaking on Nov. 29 at magnitude –4.9, 12 times brighter than Jupiter and 25 times brighter than Sirius. By mid‑December it will rise nearly four hours before sunrise, then gradually descend and disappear by July.

💡 Venus’s unprecedented early‑morning appearance offers a rare, easily visible celestial event that can spark public interest in astronomy and highlight planetary motion’s predictable beauty.
