SpaceX plans to boost Starlink network with launch
Sunday, 14 February 2021 01:08SpaceX plans to launch 60 more of its Starlink communications satellites from Florida on Sunday night as the company expands sales of the broadband internet service those satellites provide. Liftoff on a Falcon 9 rocket is scheduled for 11:20 p.m. EST, but the U.S. Space Force forecasts a 60% chance that storm clouds or a threat of lightning that could cause a postponement. Elon
UAE's 'Hope' probe sends home first image of Mars
Saturday, 13 February 2021 13:56The UAE's "Hope" probe sent back its first image of Mars, the national space agency said Sunday, days after the spacecraft successfully entered the Red Planet's orbit. The picture "captured the largest volcano in the solar system, Olympus Mons, emerging into the early morning sunlight," it said in a statement. The image was taken from an altitude of 24,700 kilometres (15,300 miles) above
Space Nuclear Propulsion Technologies central to future of Mars Exploration
Saturday, 13 February 2021 13:56Using nuclear propulsion technologies to support a human mission to Mars in 2039 will require NASA to pursue an aggressive and urgent technology development program, says a new report from the National Academies of Sciences, Engineering, and Medicine. NASA should commit within the year to conducting an extensive and objective assessment of the merits and challenges of using different types
NASA assigns astronauts to next SpaceX Crew-4 mission to ISS
Saturday, 13 February 2021 13:56NASA has assigned two crew members to launch on the agency's SpaceX Crew-4 mission - the fourth crew rotation flight of the Crew Dragon spacecraft to the International Space Station. NASA astronauts Kjell Lindgren and Bob Hines will serve as spacecraft commander and pilot, respectively, for the Crew-4 mission. Additional crew members will be assigned as mission specialists in the future by the a
Ball Aerospace to integrate and test "sailcraft" for NASA solar propulsion demonstration
Saturday, 13 February 2021 13:56Ball Aerospace has been selected to support Solar Cruiser, a NASA small satellite technology demonstration on the use of solar photons for propulsion in space. Ball will perform several mission-critical functions, including the integration and test of the satellite bus with the solar sail system that will form the completed "Sailcraft." "Solar Cruiser will be an important step in the advan
Origami-inspired antenna technology for use in small satellites
Saturday, 13 February 2021 13:56Modern telecommunication systems rely on satellites to relay signals across the globe quickly and reliably, enabling users to send messages across the world in an instant, watch live television, or - more recently - hold conference calls with global partners right from the kitchen table! Communications satellites use high-frequency radio waves to transmit data, with antennas acting as a tw
Sensors prepare to collect data as Perseverance enters Martian atmosphere
Saturday, 13 February 2021 13:56Nearly six-and-a-half months and 300 million miles since launch, NASA's Perseverance rover will land on Mars Feb. 18, 2021, to begin its robotic exploration of the Red Planet. But before Perseverance touches down on the surface of Mars, it has to achieve a successful entry, descent, and landing (EDL). Onboard the rover's protective aeroshell is the Mars Entry, Descent, and Landing Instrume
A new way of forming planets
Saturday, 13 February 2021 13:56In the last 25 years, scientists have discovered over 4000 planets beyond the borders of our solar system. From relatively small rock and water worlds to blisteringly hot gas giants, the planets display a remarkable variety. This variety is not unexpected. The sophisticated computer models, with which scientists study the formation of planets, also spawn very different planets. What the models h
Lasers reveal the secret interior of rocky exoplanets
Saturday, 13 February 2021 13:56Advances in astronomical observations have resulted in the discovery of an extraordinary number of extrasolar planets, some of which are believed to have a rocky composition similar to Earth. Learning more about their interior structure could provide important clues about their potential habitability. Led by Lawrence Livermore National Laboratory (LLNL), a team of researchers aims to unloc
Scientists develop new, faster method for seeking out dark matter
Saturday, 13 February 2021 13:56For nearly a century, scientists have worked to unravel the mystery of dark matter - an elusive substance that spreads through the universe and likely makes up much of its mass, but has so far proven impossible to detect in experiments. Now, a team of researchers have used an innovative technique called "quantum squeezing" to dramatically speed up the search for one candidate for dark matter in
Hubble uncovers concentration of small black holes
Saturday, 13 February 2021 13:56Globular clusters are extremely dense stellar systems, in which stars are packed closely together. They are also typically very old - the globular cluster that is the focus of this study, NGC 6397, is almost as old as the Universe itself. It resides 7800 light-years away, making it one of the closest globular clusters to Earth. Because of its very dense nucleus, it is known as a core-collapsed c
Vaporised crusts of Earth-like planets found in dying stars
Saturday, 13 February 2021 13:56Remnants of planets with Earth-like crusts have been discovered in the atmospheres of four nearby white dwarf stars by University of Warwick astronomers, offering a glimpse of the planets that may have once orbited them up to billions of years ago. These crusts are from the outer layers of rocky planets similar to Earth and Mars and could give astronomers greater insights into the chemistr
Chinese tracking vessel sets sail for monitoring missions in Indian Ocean
Saturday, 13 February 2021 13:56China's tracking vessel Yuanwang-6 on Wednesday departed from a port in east China's Jiangsu Province for maritime spacecraft monitoring missions in the Indian Ocean. The Yuanwang fleet will continue to carry out intensive and challenging maritime missions this year, and Yuanwang-6 alone will operate at sea for over 200 days, according to sources with the country's satellite maritime track
Proba-V's plus one
Saturday, 13 February 2021 13:56This satellite mockup, seen during antenna testing, shows the shape of ESA's new Proba-V Companion CubeSat, which is due for launch at the end of this year. The mission is a 12-unit 'CubeSat' - a small, low-cost satellite built up from standardised 10-cm boxes. It will fly a cut-down version of the vegetation-monitoring instrument aboard the Earth-observing Proba-V to perform experimental
InSight is meeting the challenge of winter on dusty Mars
Friday, 12 February 2021 10:42As dust collects on the solar panels and winter comes to Elysium Planitia, the team is following a plan to reduce science operations in order to keep the lander safe.
NASA's InSight lander recently received a mission extension for another two years, giving it time to detect more quakes, dust devils, and other phenomena on the surface of Mars. While the mission team plans to continue collecting data well into 2022, the increasing dustiness of the spacecraft's solar panels and the onset of the Martian winter led to a decision to conserve power and temporarily limit the operation of its instruments.
InSight was designed to be long-lasting: The stationary lander is equipped with solar panels, each spanning 7 feet (2 meters) across. InSight's design was informed by that of the solar-powered Spirit and Opportunity rovers, with the expectation that the panels would gradually reduce their power output as dust settled on them but would have ample output to last through the two-year prime mission (completed in November 2020).
