Could the solution to eliminating dangerous space junk be a mini-fridge-sized spacecraft equipped with a big magnet, or maybe an orbiting tug that sends out a swarm of tentacles to trap a spent rocket?
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.
On February 9, the United Arab Emirates’ Hope spacecraft is expected to enter orbit around Mars after a six-month, 300-million-mile journey from Earth.China’s space agency has been quiet about its plans for visiting the Red Planet, but the craft is expected to attempt a landing shortly after it achieves orbit.
“It’s really easy for someone to dismiss the idea and say, ‘On the back of an envelope, it looks great, but if you actually build it, you're never going to get those theoretical numbers,’” says Benkoski, a materials scientist at the Applied Physics Laboratory and the leader of the team working on a solar thermal propulsion system.
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.
There are more than a thousand asteroids with diameters larger than Didymos and Dimorphos combined, and if any of those were to strike Earth, it could lead to mass extinction and the collapse of civilization.“Everyone knows it’s possible to hit an asteroid,” says Justin Atchison, a DART mission designer at the Johns Hopkins Applied Physics Laboratory.
This might not sound like the secret to interstellar travel, but if that small lurch can be sustained, a spacecraft could theoretically produce thrust for as long as it had electric power.
These days, Al-Amiri is quarantining near the Tanegashima Space Center in Japan, where Hope is expected to depart on a seven-month journey to the Red Planet next week.“Thankfully, the most critical tests were done before the pandemic started, because two days after the team flew in, Japan imposed a two-week quarantine.”.
“It may be years before academic research institutions reach a new normal,” the paper concludes.Scientists have redirected their energy toward fighting the novel coronavirus and have shared their data; already over 13,000 papers have been written on the topic, and over 3,000 preprints related to Covid-19 research have been shared on open-access preprint sites like bioRxiv and medRxiv.
And one of the very first things NASA does when a spacecraft lands on another planet is to have it take a selfie: “Let me see your wheels in the dirt so I know you got there safely.” Or “Snap a photo of your solar panels so we can see how dirty they are.” A simple selfie can tell a science team if an instrument is broken, say, or how close it might be to an object.
Humans saw the Earth from space for the first time in 1946 from a V-2 rocket, and subsequent images of the planet can make people feel a little, well, protective.Photograph: NASA/JPLEach of NASA’s Apollo missions had a shot list of photos to take, but this image, Earthrise, was not one of them.

The word “corona” has Latin roots, meaning essentially “crown.” The solar corona is the outermost region of the Sun’s atmosphere, a hazy aura made of colder plasma that is released from the surface of the star.

The photo was taken with NASA’s Wide-field Infrared Survey Explorer—a telescope with a very wide lens that looks at the universe in infrared light.

Known as the Long-Lived In-situ Solar System Explorer, or LLISSE, each of the probe’s components is specially engineered to withstand the high temperature, high pressure, and reactive atmosphere that define that infernal planet.“We don't have any data on how the conditions change from day to night on Venus,” says Kremic.
The show is one of the first series appearing on the (now named) Apple TV+ streaming service, a multibillion-dollar push that includes projects from Steven Spielberg and Oprah Winfrey.
Milano, who helps run the Space Sciences Laboratory at UC Berkeley, had been gearing up for a satellite launch.Normally, NASA wouldn’t let mission control run on anything less than a stable grid connection, says Steven Beckwith, the lab’s director.
Not only were they the first spacecraft to visit the asteroid belt, Jupiter, and Saturn; they even carried with them a plaque that carried a message on behalf of all humankind.
And while this image is incredibly detailed, Cassini was a whopping 870,000 miles above the plane of the rings when it took this photo in 2014.Photograph: NASA/JPL-Caltech/Space Science InstituteThis maelstrom on Saturn is one of the biggest storms ever observed on the planet.
Launched in 2018, NASA’s Parker Solar Probe will take years to swoop into orbit around the Sun, but once it’s there, its main goal is to figure out exactly what drives the solar wind, the constant stream of highly charged particles that are spit out from the openings in the surface.
Zellner says the best way to settle the lunar cataclysm debate will be to visit craters where samples aren’t likely to have been contaminated by the Imbrium impact, such as the south pole or the far side of the moon.
According to Koenigsmann, the explosion occurred during a test of the Crew Dragon’s in-flight abort system, which is used to jettison the capsule from the rocket if something goes wrong during launch.
Space Photos of the Week: A Tribute to Voyager’s Twin Trippers. In late August and early September of 1977, NASA launched twin spacecraft, Voyager 1 and 2. However, after their revolutionary discoveries, NASA extended the missions and sent Voyager 2 onward to Uranus and Neptune.
But it’s never dreamed up ion propulsion, a fantastical new way to power robots by accelerating ions instead of burning fuel or spinning rotors. But that’s a ways off, because at the moment the four-thruster machine can produce a bit more thrust than it needs to get its weight off the ground.
The Dragonfly mission will spend two years flying around the surface of Titan, studying the moon’s composition and searching for signs of life. On Wednesday, NASA announced it will send a spacecraft to the surface of Titan , Saturn’s largest moon and one of the leading candidates for finding extraterrestrial microbial life in our solar system.
The Planetary Society pressed on and a decade later launched the LightSail 1 into low Earth orbit. In 2010, the Japanese space agency launched IKAROS , which used solar sailing as its only form of propulsion on a mission to Venus and demonstrated that the technology actually worked for the first time.
