ESA’s Rosalind Franklin Mars rover has been delayed twice due to problems with its parachute deployment and Russia’s invasion of Ukraine. After ESA formally terminated the mission’s cooperation with Roscosmos in July 2022‚ Europe found a new partner with NASA and the mission appears to be on track for a 2028 launch. The agency recently shared a new animated mission trailer showing new details about the rover‚ including how it will drill two meters into the Martian regolith and examine the samples with its onboard laboratory. Rosalind Franklin’s mission is to search for past and present signs of life on Mars. Additionally — as has been the mission for every Mars rover — Rosalind Franklin will the search for evidence of past water on the Red Planet. The video suggests three might be oceans to discover.   The landing site for this mission is Oxia Planum‚ a region located between two outflow channel systems: Mawrth Vallis to the northeast and Ares Vallis to the southwest. Scientists believe this region will contain remnants of the planet’s wetter past. The Rosalind Franklin rover will land in Oxia Planum‚ indicated in this global Mars map. Credit: ESA Rosalind Franklin will be equipped with cameras which can help characterize the surface environment‚ as well as document the use of the drill and the samples collected. Being able to drill at least two meters below the surface of the Mars regolith will allow for studying samples that have been protected from surface radiation and extreme temperatures. The onboard laboratory will process samples and deliver them to three instruments. Minerals will be characterized by the MicrOmega instrument; a Raman spectrometer will provide data concerning mineralogical composition; and part of the Mars Organics Molecule Analyser (MOMA) will study and identify soil chemistry. and characterize the surface environment. The rover is expected to drive up to 70 meters per Martian day‚ or Sol. An artist’s illustration of the ExoMars/Rosalind Franklin rover on Mars. Image Credit: ESA/ATG medialab Also with this mission‚ ESA is looking to demonstrate key technologies that are needed for future planetary exploration missions. This includes the capability to land safely on a planet‚ to move autonomously on the surface‚ and to perform drilling and sample processing and analysis automatically. The rover has the ability to use some novel driving techniques‚ such as wheel-walking to overcome difficult terrains‚ as well as autonomous navigation software. The mission is currently set to launch between October 5th and the 25th in 2028‚ with a projected landing on October 28‚ 2030.

After a brief interruption‚ NASA announced that the Hubble Space Telescope is back in business. Problems with one of its gyros put the Hubble into safe mode back on November 19th. Now‚ the issue has been dealt with‚ and the world’s most productive space telescope is back online. The telescope automatically put itself in safe mode on the 19th after one of its gyros failed‚ but engineers recovered it the next day. The gyro problem resurfaced again and the telescope suspended science operations again on the 21st. Again‚ it was recovered‚ and again‚ it went into safe mode on November 23rd. Science operations were suspended until December 8th. Now engineers have dealt with the problem and the space telescope has resumed science operations. NASA’s Hubble Space Telescope resumed science operations on Friday‚ Dec. 8‚ after it paused science observations on Nov. 23 due to an issue with one of its gyros.The spacecraft is in good health and once again operating using all three of its gyros: https://t.co/5WyVDn2KX4 pic.twitter.com/mFS3lInN6j— Hubble (@NASAHubble) December 8‚ 2023 The gyros are part of the telescope’s guidance and aiming system‚ along with the Fine Guidance Sensors and the Reaction Wheels. The Hubble’s gyros have caused problems before. Science operations were suspended in 2018 due to problems with the gyros. “…these gyros have a mind of their own‚” said STScI director at the time‚ Ken Sembach. When Hubble was launched in 1990‚ it had six gyros. Those failed and were replaced with six new ones with a different design in 2009. Now‚ three of those have failed‚ and Hubble is down to the last three. There are no more servicing missions to the Hubble‚ so when these last three finally fail‚ the Hubble will be just a relic. A celebrated relic‚ but a relic nonetheless. The Hubble still has life left in it‚ though. NASA expects the gyros to last into the 2030s. In the meantime‚ expect periodic failures‚ safe modes‚ and science operation suspensions. Even though the telescope was interrupted when one of its gyros went wonky‚ there’s still lots of life left. The Hubble can operate with a single gyro if necessary. That will impact its work but it won’t end it. Though the telescope is back in operation‚ it’s not fully operational. The Wide Field Camera 3 and Advanced Camera for Surveys resumed science observations on Friday December 8th. But the  Cosmic Origins Spectrograph and Space Telescope Imaging Spectrograph are still offline. The Hubble team expects to have them working later in December. This sparkling starfield was captured by the NASA/ESA/CSA Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys. It contains the globular cluster ESO 520-21 (also known as Palomar 6). Hopefully‚ the Hubble will be fully operational again soon‚ and we can enjoy more of its work. Image Credit: NASA/CSA/ESA/STScI When science operations were suspended‚ it impacted the telescope’s schedule. There were scheduled observations supporting research into Kuiper Belt Objects‚ metallicity in the Andromeda Galaxy’s satellites‚ Type 1A supernovae‚ and other topics. With the problem resolved‚ hopefully‚ some of this work will resume. The HST has been in operation for more than 30 years now‚ and there’s nothing else comparable to it. It has advanced astronomical and astrophysical science like no other telescope or facility. An entire generation of people have grown up with it‚ and since the advent of the internet‚ its images have reached billions of pairs of eyes. It’s changed us. There’ll likely be more problems cropping up more frequently as the telescope moves toward its final observation. But as Hubble engineers keep showing us‚ we can’t ever really count the telescope out. The post Hubble Returns to Science Operations appeared first on Universe Today.
