Mission Overview Studying Mars' Habitability, Seeking Signs of Past Microbial Life, Collecting and Caching Samples, and Preparing for Future Human Missions The Perseverance rover has four science objectives that support the Mars Exploration Program's science goals: All address key astrobiology questions related to the potential of Mars as a place for life. The first three consider the possibility of past microbial life. Mars 2020 Technology: Heritage and Innovation Technologies for Entry, Descent, and Landing The mission uses technological innovations already demonstrated successfully, especially for entry, descent, and landing (EDL). This type of landing system provides the ability to land a very large, heavy rover on the surface of Mars in a more precise landing area than was possible before Curiosity's landing. Technologies for Surface Operations The Perseverance rover design minimizes costs and risks because it is largely based on the engineering design for the previous Curiosity rover.

The Lunar Library: Genesis — Arch Mission Foundation - Preserving humanity fo... The Arch Lunar Library™ represents the first in a series of lunar archives from the Arch Mission Foundation, designed to preserve the records of our civilization for up to billions of years. It is installed in the SpaceIL “Beresheet” lunar lander, which crashed on the Moon in April of 2019. The Lunar Library contains a 30 million page archive of human history and civilization, covering all subjects, cultures, nations, languages, genres, and time periods. The Library is housed within a 100 gram nanotechnology device that resembles a 120mm DVD. The first four layers contain more than 60,000 analog images of pages of books, photographs, illustrations, and documents - etched as 150 to 200 dpi, at increasing levels of magnification, by optical nanolithography. The first analog layer is the Front Cover and is visible to the naked eye. Beneath the analog layers of the Library are 21 layers of 40 micron thick nickel foils, each containing a DVD master.

India Is Headed to the Moon India has successfully launched its second lunar mission, Chandrayaan-2. The country hopes that the launch will make bring it into the exclusive club of nations that have successfully made a soft landing on lunar soil. Riding on an Indian-built rocket known as a Geosynchronous Satellite Launch Vehicle, or GSLV MkIII-M1, the successful launch from the Second Launch Pad at the Satish Dhawan Space Center, located on a small island off India's southeastern coast, took place at 2:43 pm Indian Standard Time (IST). "Today is a historical day for Space Science and Technology in India. The launch wasn't entirely smooth. “Today is the beginning of the historical journey of India towards Moon and to land at a place near south pole to carry out scientific experiments to explore the unexplored. What is Chandrayaan-2? Chandrayaan-2 is a lunar mission comprising of three parts: a lander called Vikram, a rover called Pragyan, and a lunar orbiter. Until today, the mission has been delayed several times.

NASA's Juno spacecraft enters Jupiter's orbit | NASA News Fast Facts The $1.1bn mission will last 20 months Juno has travelled 2.7bn km since its launch in 2011 It's an unmanned solar-powered observatory A key concern are high radiation levels NASA's Juno spacecraft has begun to orbit Jupiter to investigate the origin of the solar system, the US space agency has said. The $1.1bn mission launched five years ago successfully entered the orbit of Jupiter, the largest planet in the solar system, after a 35-minute manoeuvre, NASA said on Tuesday. "Success! The unmanned solar-powered observatory has travelled 2.7bn kilometres since it was launched five years ago from Cape Canaveral in Florida. Once in position to begin its 20-month science mission, Juno will fly in egg-shaped orbits, each one lasting 14 days, to peer through the planet's thick clouds, map its gargantuan magnetic field and probe through the crushing atmosphere for evidence of a dense inner core.

China's Chang'e 4 makes historic first landing on the moon's far side By Leah Crane For the first time, a spacecraft has landed on the side of the moon that is always facing away from Earth – an area that, until now, we had only seen from orbit. The China National Space Administration’s Chang’e 4 lander launched on 7 December and has spent the past month reaching the correct orbit to attempt the historic landing. The CNSA also launched a lunar satellite in May to facilitate communication with the lander, as there is never a direct line of sight between the moon’s far side and Earth. That lack of visibility meant that Chang’e 4 had to make its landing almost completely autonomously, with no input from mission control. At 10.26 am Beijing time on 3 January, the lander successfully touched down on the surface in an enormous depression called the South Pole-Aitken basin. This basin is particularly important because it is thought to be a crater from a huge impact during the moon’s early years. The mission will also help prepare for the moon’s possible future.

New Horizons Spacecraft Wakes Up to Prepare for Historic Flyby of Distant Object NASA's New Horizons spacecraft has woken up from hibernation to prepare for a historic New Year's Day flyby at the edge of our solar system. The New Horizons probe, which flew by Pluto in July 2015, has been in hibernation mode since Dec. 21 to preserve resources. But, on June 5, the mission operations team at Johns Hopkins Applied Physics Laboratory received confirmation, through NASA's Deep Space Network, that the spacecraft had exited hibernation, as it was programmed to do. The spacecraft will now begin preparations for a New Year's flyby encounter with the farthest planetary encounter in history. "Our team is already deep into planning and simulations of our upcoming flyby of Ultima Thule and excited that New Horizons is now back in an active state to ready the bird for flyby operations," the mission's principal investigator, Alan Stern, of the Southwest Research Institute in Boulder, Colorado, said in a statement.

Watch the Final Moments of the ESA's Rosetta Spacecraft as It Crashes Into a Comet In Brief After more than 10 years in space, the ESA's "comet chaser" has ended its mission. Rosetta's missions have been credited with revitalizing public interest in comets. The European Space Agency’s (ESA) Rosetta spacecraft finished its final mission on her comet, the 67P, today at 5 AM Eastern Time. “Rosetta has entered the history books once again,” says Johann-Dietrich Wörner, ESA’s Director General, in a press release. The much-accomplished satellite contributed a great deal to space exploration, particularly to the study of comets. For additional insight, the ESA has released a video that shows Rosetta’s final trajectory. Bittersweet feeling as Cassini mission embarks on its 'grand finale' ahead of death plunge It’s the slow beginning of what will be a violent end for the Cassini mission. At 10.00 BST on April 26, the spacecraft became the first ever to dive between Saturn and its spectacular innermost ring. This marks the start of its “grand finale” consisting of 22 daring orbits – enabling a new era of science. Then, on September 15, it will crash into the planet’s atmosphere and burn up. Cassini was initially set on its path to destruction on April 22 when it flew by Saturn’s moon Titan. During the next few months, the instrument teams have several new observations to make in this region. Hazardous journey But there are risks. However, it is thought that the risks of a significant dust hit in the ring plane are low. The only protruding features beyond the shield are a 10-metre electric field antennae and an 11-metre magnetometer boom (used to make magnetic observations). Indeed, the best computer models show that this should not happen. Personal highlights

Ariel (moon) Ariel is the fourth-largest of the 27 known moons of Uranus. Ariel orbits and rotates in the equatorial plane of Uranus, which is almost perpendicular to the orbit of Uranus and so has an extreme seasonal cycle. It was discovered in October 1851 by William Lassell and named for a character in two different pieces of literature. As of 2017, much of the detailed knowledge of Ariel derives from a single flyby of Uranus performed by the spacecraft Voyager 2 in 1986, which managed to image around 35% of the moon's surface. There are no active plans at present to return to study the moon in more detail, although various concepts such as a Uranus orbiter and probe have been proposed from time to time.

Pluto Has Dunes, But They're Not Made of Sand Pluto is an uncanny-valley world, with landscapes and vistas that seem strikingly similar to those of Earth — until you take a closer look. NASA's New Horizons mission, which flew by the dwarf planet in July 2015, found that Pluto has towering mountains, but of water ice rather than rock; vast plains of frozen nitrogen and other exotic materials; and blue skies provided by a wispy atmosphere that contains no appreciable oxygen. And now, a new study reveals another alien parallel: Pluto has an extensive dune system, but the grains that make up the wind-blown mounds are certainly not sand. [Destination Pluto: NASA's New Horizons Mission in Pictures] The new discovery "shows us that Pluto's atmosphere and surface are interacting in a way that geologically/geomorphologically alters the surface," said study lead author Matt Telfer, a lecturer in physical geography at the University of Plymouth in England. "We're sure," Telfer said. Dune systems appear to be common throughout the solar system.
