Waymo shares some of its self-driving car data to help researchers
Self-driving car data is intensely valuable, and it's frequently considered one of Waymo's advantages -- it has more experience than virtually anyone. Now, however, the company is sharing some of that knowledge with the rest of the world. It's launching a Waymo Open Dataset that gives researchers free access to synced camera and LiDAR data from the company's autonomous vehicles across a variety of driving conditions and locales. It only covers 1,000 driving segments of 20 seconds each, but that's 200,000 frames per sensor, 12 million 3D object labels and 1.2 million 2D labels -- that could be a lot to work with.
NASA confirms mission to Jupiter's moon Europa
NASA has been talking for years about sending a probe to Europa, and now it's locking down those plans. The agency has confirmed the next phase of its Europa Clipper mission, which will send a spacecraft to the Jovian moon to determine if it could support life. The move allows progress toward finishing and testing a final design for the spacecraft. The administration is developing for a 2023 launch target to ensure a "cost-effective" process, but it's prepared to launch as late as 2025.
‘Kerbal Space Program’ gets an interstellar flight sequel
It's been four years since Kerbal Space Program (KSP) -- the spacecraft building and flight simulation game -- officially launched. While Elon Musk once called the title "awesome" and joked that SpaceX used KSP for testing software, it was due for a refresh. Today, Private Division announced that Kerbal Space Program 2 (KSP2) will arrive in 2020. As part of the reveal, it released cinematic trailer and a (dramatic) developer story.
NASA selects proposals for smallsats built to study deep space
NASA is expanding plans to use small satellites (aka smallsats) to explore the Solar System. The agency has picked two proposals for smallsat technology that would improve observations in deep space, where they could help improve models that predict space weather. One, Science-Enabling Technologies for Heliophysics (SETH), would demo both optical communications as well as a detector that can spot fast-moving chargeless atoms emanating from the Sun. Solar Cruiser, meanwhile, would include both a giant 18,000 square foot solar sail as well as a coronagraph that could study both the Sun's magnetic field as well as the velocity of coronal mass ejections.
SpaceX Starman Roadster completes its first orbit around the Sun
Starman and his Tesla Roadster are now regular denizens of space. According to data from Where is Roadster, the cosmic driver has completed his first orbit around the Sun, taking 557 days since the first Falcon Heavy launch to circle our home star. Its path has taken it over 762 million miles since then, or enough to exceed its original 36,000-mile warranty over 21,000 times.
Sticker sensor monitors your body using wireless power
Wearable body sensors have a common problem: they need power and antennas, and all that equipment leads to bulky devices that influence your behavior. Stanford researchers, however, have developed a system that could be almost imperceptible. Their BodyNet sticker sensor gathers power and transmits data using an RFID connection to a receiver on nearby clothing, making the sensor itself about as comfortable and flexible as an adhesive bandage. It measures subtle changes in skin that provide a wealth of data for the body, whether it's your heartbeat, breathing rate or muscle activity.
Virgin Galactic's Spaceport America is no longer an empty hangar
Virgin Galactic has officially opened Spaceport America's "Gateway to Space" building few months after it started moving its staff and spacecraft to the New Mexico facility. In addition, the VMS Eve has arrived at the spaceport this week, which Chief Pilot Dave Mackay says brings "Virgin Galactic closer to starting commercial service." VMS Eve is the aerospace company's launch vehicle, in charge of carrying its spacecraft to the skies before dropping it mid-air.
NASA chooses four potential asteroid sample sites for OSIRIS-REx
NASA's OSIRIS-REx team has selected four potential sites for the agency's first asteroid sample return mission. The spacecraft started mapping asteroid Bennu's surface as soon as it arrived in late 2018, and scientists part of its ground team thought they'd be choosing the final two candidate sites at this point in time. Observations made from our planet showed that the asteroid had large areas with fine-grain materials, but images the spacecraft took showed the truth: Bennu has an especially rocky terrain, making it a challenge to collect materials less than 1 inch in diameter. That's the maximum size the probe's sample mechanism can handle.
Second failure of ExoMars parachute test throws schedule in jeopardy
A joint mission between the European and Russian space agencies to deliver a rover to Mars is facing another setback. The European Space Agency (ESA) confirmed that parachutes for the ExoMars lander mission failed a second test that was conducted last week. A similar trial conducted back in May on the same parachutes also ended up malfunctioning. Scientists observed damages in the canopy in both cases.
Supercomputer creates millions of virtual universes
How do you understand the development of galaxies when even the younger examples are frequently billions of years old? Simulate as many universes as you can, apparently. Researchers at the University of Arizona have used the school's Ocelote supercomputer as a "UniverseMachine" that generates millions of mini universes to see how well they line up with the real cosmos. Rather than try to portray every nuance of the whole universe (even a single fully modeled galaxy would require far too much computing power), the team devised a system that had just enough resolution to scale from supernovae to a "sizeable chunk" of observed space. Each virtual universe had a different set of rules, and it was largely a matter of seeing which simulations lined up the closest with real data.
Scientists find the largest observed black hole to date
Astronomers aren't done with major black hole discoveries this year. The Max Planck Institute's Kianusch Mehrgan and colleagues have found the largest black hole ever observed at the center of Holm 15A, a galaxy about 700 million light-years away. It's more than twice as large as the previous observed record-setter at 40 billion times the mass of the Sun, and 10,000 times the mass of the black hole at the core of the Milky Way.
‘No Man’s Sky Beyond’ trailer reveals expanded multiplayer and VR
Players can get their first look at the world of No Man's Sky: Beyond, the long-awaited update to the popular space exploration franchise. Hello Games just released the first trailer for Beyond, which will include even more MMO-style gameplay and support for VR. After last summer's Next set the stage for what multiplayer mode and shifting perspectives could bring to the game, expectations have been high.
Watch SpaceX catch a piece of its rocket as it falls from space
Yesterday, SpaceX successfully launched a Falcon 9 rocket from Cape Canaveral. This was the third flight for this particular Falcon 9, and its mission was to carry the AMOS-17 satellite for Spacecom. While you can watch the full launch stream here, one of the most exciting parts of yesterday's event came as a tweet from Elon Musk. He shared a quick video of a SpaceX ship catching the rocket's fairing in a net as it fell from space.
Rocket Lab will reuse its rockets by catching them with a helicopter
SpaceX won't be the only company reusing its rockets for payload deliveries. Rocket Lab has unveiled plans to recover the first stage of its Electron vehicle. The strategy's first phase will have Rocket Lab recovering the stage from the ocean and refurbishing it for later. A second phase will be more... audacious. The company intends to have the stage "captured mid-air" by a helicopter, with the aircraft hooking on to the rocket's parachute array during the descent. It won't be as elegant as SpaceX's rocket landings, but it will be efficient if it works as planned.
SpaceX 'rideshare' program launches satellites for just $2.5 million
For space tech startups and other small companies doing research, one of the biggest hurdles is actually getting to space. SpaceX is looking to change that. Today, it announced a SmallSat Rideshare Program, which will allow small satellite operators to book a spot on regularly scheduled Falcon 9 launches.
Faster algorithm could lead to more realistic sounds in VR
Producing realistic sound models in VR is tricky, even compared to conventional video games. You don't always know how objects will sound in a given environment or where the listener will be, and you don't have the luxury of waiting hours for conventional sound modelling to finish. Thankfully, Stanford researchers have found a way to produce those models in a viable time frame. Their algorithm that can calculate 3D sound models in mere seconds -- not real-time, but quickly enough that you could pre-calculate sound models for very specific situations.
Meteor impact may have started a 'mega-tsunami' on early Mars
There appears to be stronger evidence of a possible ocean on ancient Mars. A recent study indicates that the meteor that created the 75-mile Lomonosov crater may have produced a "mega-tsunami" that left its mark on the planet. Its rim is the same height as the estimated depth of the ocean and resembles marine craters on Earth. Also, a hole in the southern lip of the crater could have been the result of the ocean roaring back from that direction. Earlier evidence had hinted the ocean's shores were shaped by at least one impact in the same general area as the Lomonosov crater -- this latest study, however, has narrowed things down to a specific impact site.
NASA solar probe sends back data from its first two visits
Over the past months, NASA's Parker Solar Probe flew closer to the sun than any other spacecraft before it -- not once, but twice on two flybys. The probe obviously collected as much data as it could so that we can understand the sun better. Now its mission team at Johns Hopkins Applied Physics Laboratory in Maryland has just received the final transmission for the 22 gigabytes of science data collected during those two encounters. That's 50 percent more than it expected to receive by now, all thanks to the spacecraft's telecommunications system performing better than expected.
Electrify America will use robots to charge self-driving EVs
As self-driving and electric vehicles advance, one fundamental question remains: How will autonomous EVs connect to charging stations? Volkswagen-backed Electrify America and Stable Auto hope to answer that. The two companies are working together to develop robotic charging stations for self-driving vehicle fleets.
LightSail 2 successfully demonstrates solar sailing
LightSail 2 is faring much better than its ill-fated predecessor. The Planetary Society has verified that LightSail 2 successfully raised its orbit using solar sailing, making it the first small spacecraft to demonstrate the concept (though Japan's IKAROS was the first of any kind to fly). The team is now focused on raising the solar sailer's orbit for about a month's time as it continues to improve sail control through software updates and new techniques.
