NASA’s Perseverance rover is now halfway to Mars

The spacecraft has covered half the distance it will go to Mars and will arrive in February, hopefully safely.

After years of detective work, scientists working on the European Space Agency (ESA) Rosetta mission have now been able to locate where the Philae lander made its second and penultimate contact with the surface of Comet 67P/Churyumov-Gerasimenko on 12 November 2014, before finally coming to a halt 30 metres away. This landing was monitored from the German Aerospace Center Philae Control Center. Philae left traces behind; the lander pressed its top side and the housing of its sample drill into an icy crevice in a black rocky area covered with carbonaceous dust. As a result, Philae scratched open the surface, exposing ice from when the comet was formed that had been protected from the Sun’s radiation ever since. The bare, bright icy surface, the outline of which is somewhat reminiscent of a skull, has now revealed the contact point, researchers write in the scientific publication Nature.
All that was known previously was the location of the first contact, that there had been another impact following the rebound, and the location of the final landing site where Philae came to rest after two hours and where it was found towards the end of the Rosetta mission in 2016. “Now we finally know the exact place where Philae touched down on the comet for the second time. This will allow us to fully reconstruct the lander’s trajectory and derive important scientific results from the telemetry data as well as measurements from some of the instruments operating during the landing process,” explains Jean-Baptiste Vincent from the DLR Institute of Planetary Research, who was involved in the research published today. “Philae had left us with one final mystery waiting to be solved,” says ESA’s Laurence O’Rourke, the lead author of the study.
Space — The final frontier, and for Soviet cosmonaut, Sergei Krikalev, it nearly was his final frontier! Check out today’s new video where a soviet astronaut was on a space mission, meanwhile the USSR crumbled,… More making him the last citizen of the Soviet Union. How did Sergei finally get home, and what home would he be coming back to? Check out this epic new space story to find out!
New results from NASA’s Juno mission at Jupiter suggest that either “sprites” or “elves” could be dancing in the upper atmosphere of the solar system’s largest planet. It is the first time these bright, unpredictable and extremely brief flashes of light—formally known as transient luminous events, or TLE’s—have been observed on another world. The findings were published on Oct. 27, 2020, in the Journal of Geophysical Research: Planets.
Scientists predicted these bright, superfast flashes of light should also be present in Jupiter’s immense roiling atmosphere, but their existence remained theoretical. Then, in the summer of 2019, researchers working with data from Juno’s ultraviolet spectrograph instrument (UVS) discovered something unexpected: a bright, narrow streak of ultraviolet emission that disappeared in a flash.
“UVS was designed to characterize Jupiter’s beautiful northern and southern lights,” said Giles, a Juno scientist and the lead author of the paper. “But we discovered UVS images that not only showed Jovian aurora, but also a bright flash of UV light over in the corner where it wasn’t supposed to be. The more our team looked into it, the more we realized Juno may have detected a TLE on Jupiter.”

Astronauts photograph our home planet from space almost daily, contributing to a growing archive of over 3 million Earth observations.

Jupiter’s lightning seems to produce brilliant flashes of light high above its water clouds — alien versions of Earth’s red sprites and elves.

This week, NASA’s OSIRIS-Rex spacecraft successfully touched and collected a sample from the surface of asteroid Bennu—without a human at the controls…
NASA scientists identified a molecule in Titan’s atmosphere that has never been detected in any other atmosphere. In fact, many chemists have probably barely heard of it or know how to pronounce it: cyclopropenylidene, or C3H2. Scientists say that this simple carbon-based molecule may be a precursor to more complex compounds that could form or feed possible life on Titan.
