In mid-March, NASA researchers announced that they’d found an unknown life-form hiding aboard the International Space Station.As part of an ongoing research project into the microbial life of the ISS, astronauts onboard in 2015 and 2016 swabbed down various parts of the station and sent home the wipes they used.
The sun’s magnetic fields are massive, but within its inner layers, their forces are channeled and controlled by the pressure of the superheated plasma, convecting its heat outward like a boiling pot of tomato soup.
Last week, TechCrunch found that Amber Group, the contractor that developed the platform, had an exposed Amazon Web Services cloud server that contained more than 70,000 negative Covid-19 test results and more than 425,000 immigration documents from travelers entering Jamaica.📩 The latest on tech, science, and more: Get our newsletters !How to remember a disaster without being shattered by it A trippy visualization charts the internet's growth since 1997 TV characters don’t have text history.
NASA Lands the Perseverance Rover on Mars.The Atlas V rocket transporting NASA’s latest Mars rover launched from Florida’s Kennedy Space Center in July and has spent the past six months en route to the Red Planet.
The Lockheed engineers had been working on this project for years, and today, Scholz and his team could finally watch it be put to use.
And the experiments get power from a battery that continuously recharges with US-made plutonium fuel .Since July, as Perseverance has been cruising toward Mars, the numerous antennae aboard have been pinging high-frequency signals to engineers back on Earth.
Embedded on the rover is a small microphone that, if all goes well, will record the sounds of the descent and, later, the martian environment itself, something no Mars probe has yet achieved.NASA Just Launched Its New Perseverance Rover to Mars.
Under the existing standard, some veteran astronauts might have been excluded from longer-term space missions because they are bumping up against lifetime radiation limits.But NASA doesn’t have much data on the health effects of radiation from space on its astronauts.
The AI discovered dozens of them hiding in image data from the Mars Reconnaissance Orbiter and revealed a promising new way to study planets throughout our solar system.
“I don’t think there’s much going to happen that will change that, barring a massive volcano,” says Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, which released the atmospheric data along with NOAA.
Another possibility, given the surprisingly viscous surface material, is that the regolith’s soft, malleable rocks wedged into the Mylar flap opening and weren’t able to make it all the way into the head, Moreau says.
By looking at the change in rotational rate for the spacecraft, you can determine the amount of extra mass in the collector arm.Let me go over all the important pieces to this physics puzzle.
“NASA has been very open about the fact that in order to do exploration beyond low earth orbit, you have to have a platform there to test systems and get experience,” says Michael Suffredini, the cofounder and CEO of Axiom Space, a company that is poised to build the world’s first commercial space station.
I’ve been to polluted cities, but you never get that deep orange, ominous color,” says Sanaz Vahidinia, a physicist at NASA Ames Research Center who studies aerosols and light scattering.
Behnken and Hurley spent the next few hours drifting in orbit while NASA and SpaceX monitored weather conditions at the possible landing sites along the Florida coast.SpaceX mission control made the final decision to deorbit just an hour before Behnken and Hurley landed in the ocean.
The skycrane is outfitted with eight small engines that start firing when the rover is about half a mile up to rapidly slow its fall to just a few miles per hour.“These particular engines are actually a derivative of the original engines developed for Viking landers in the early ’70s, but we've made very significant upgrades,” says Fred Wilson, a propulsion expert at Aerojet Rocketdyne, the company that made the propulsion system for the Perseverance landing system.
Perseverance is only the second Mars rover to use nuclear power as its main source of electrical energy.Starting with Curiosity, which arrived on the Red Planet in 2012, NASA engineers switched to nuclear power as the rover’s main source of energy.
“I see it as kind of a Wright brothers moment on another planet,” says Bob Balaram, the chief engineer for the Mars helicopter project at NASA’s Jet Propulsion Laboratory.
PTC’s software combines several different approaches to AI, like generative adversarial networks and genetic algorithms.A generative adversarial network is a game-like approach in which two machine-learning algorithms face off against one another in a competition to design the most optimized component.
Voyager 2 had a bit more to do; not only would it also visit Jupiter and Saturn, it would become the first spacecraft to fly by Uranus and Neptune.Photograph: NASA/JPLAfter traveling about 400 million miles, Voyager 2 arrived at Saturn, where it snapped this seemingly sideways photo of the ringed beauty.
On Wednesday, NASA astronauts Bob Behnken and Doug Hurley were supposed to launch to the International Space Station in SpaceX’s Crew Dragon capsule.
The Demo-2 mission was going to be the first crewed mission for SpaceX and the first time NASA astronauts have launched from the US in nine years.
NASA and SpaceX have been working toward this goal for over a decade and this launch is the last major test before NASA certifies the Crew Dragon for human spaceflight .Behnken and Hurley will depart from historic launch pad 39-A at NASA’s Kennedy Space Center in Florida.
