A Japanese spacecraft has dropped two small rovers onto the surface of an asteroid zooming through space. If they land safely, the unmanned Hayabusa-2 would be the first spacecraft to ever successfully place robotic rovers onto a space rock. Japan’s space agency (JAXA) hopes that the mission will provide clues about the origin of the solar system. Recommended Japanese space agency to land spacecraft on asteroid The agency is expecting to receive data from the rovers at some point on Saturday confirming whether or not the mission has been a success. Hayabusa-2 first arrived near the asteroid, known as Ryugu and situated 280 million km (170 million miles) from Earth, in June. The spacefract approached as close as 55m (180 feet) to the asteroid, dropping the rovers and waiting for a minute before rising back to its waiting position about 20 km (12 miles) above the surface. JAXA said the release went successfully. The solar-powered rovers’ voltage plunged as night fell on Ryugu, a sign that they are on the asteroid, according to Hayabusa project team spokesman Takashi Kubota.

The vehicle is Hayabusa2, and the rovers were the first in a series of robots that the vehicle will throw at the asteroid’s surface over the next few months. Operated by the Japanese Aerospace Exploration Agency (JAXA), Hayabusa2 is tasked with grabbing a sample from an asteroid named Ryugu and returning those materials to Earth. The spacecraft launched in 2014 on top of a H-IIA rocket and arrived at Ryugu in June. It will grab multiple samples from the asteroid in the year ahead before heading back to our planet late next year. the first in a series of robots that the vehicle will throw at the asteroid’s surface Ultimately, the goal is to learn more about this asteroid and get a better understanding of what these types of objects are made of. Asteroids like Ryugu are thought to be remnants of the early Solar System, remaining relatively unchanged over the last 4.5 billion years. So they provide a good snapshot of what our cosmic neighborhood was like when the planets were first forming. Studying just a small sample of an asteroid gives scientists a lot of precious information about how our planetary system came to be. Before Hayabusa2 grabs its samples, the spacecraft will shower Ryugu in robots. The first two that were deployed are Rover-1A and 1B. Hayabusa2 ejected them from a drum called MINERVA-II1 around 12:35AM ET after descending toward Ryugu and coming within 200 feet of the asteroid’s surface. Cylindrical in shape, the rovers are equipped with multiple cameras and temperature sensors to map and image Ryugu. Unlike NASA’s Mars rovers, these mobile bots don’t have wheels. They actually have rotating motors buried within them that enable the rovers to shift their momentum and hop across the surface of the asteroid. Though their purpose is to gather data, Rover-1A and 1B are also meant to demonstrate that bots can explore a low-gravity environment. Ryugu is a little more than half a mile across, so it doesn’t boast a very strong gravitational pull. That’s why the bots can’t have normal wheels; otherwise, they’d just float away. But this hopping strategy should allow the rovers to explore the surface of Ryugu autonomously without drifting off. MINERVA-II1, the drum that housed the rovers, is actually named after a lander that was carried on the original Hayabusa mission, another JAXA mission that launched in 2003 and became the first vehicle to retrieve samples from an asteroid. However, that lander, named MINERVA, was accidentally released when Hayabusa was too far away from its asteroid, so it got flung out into space and never landed. We still don’t have official confirmation from JAXA yet that these new rovers did indeed touch down on Ryugu. But if they did land successfully, they will have finally fulfilled part of the mission that Hayabusa had originally meant to accomplish. If Rover-1A and 1B are on Ryugu, they will have more company soon If Rover-1A and 1B are on Ryugu, they will have more company soon. In October, Hayabusa2 will release another lander, made by the German Aerospace Center, called MASCOT. That vehicle will be released from 328 feet away, and once it’s on the surface, it will also hop across the asteroid in a similar way as the rovers. It’s equipped with four different instruments to measure the geology of Ryugu, as well as study the temperature and magnetic field of the object. Sometime in the coming months, Hayabusa2 will deploy its fourth bot, another rover inside a second drum container called MINERVA-II2. Of course, the primary goal of Hayabusa2 is to get samples, and the spacecraft will employ some very creative techniques to get up to three different sets of material from Ryugu. The first couple of sample grabs will entail Hayabusa2 getting up close to the asteroid and then shooting it with a gun-like device. That will hopefully stir up enough debris that the probe can gather into its sample collector. The third sample collection will be much more explosive. Hayabusa2 will attempt to scoop up material from deep within Ryugu, where the rock has been largely unaffected by the space environment. To do that, the spacecraft is going to first set off a small explosive projectile, which will make a crater on the surface. Then, Hayabusa2 will dive into the hole it’s created and gather more rocks. Altogether, the spacecraft should gather a tiny amount of material: just 100 milligrams of dust All of this will take place over the next year — Hayabusa2 is scheduled to leave Ryugu in late 2019 — so there’s still a long way to go. In the meantime, another US spacecraft will try to capture a lot more material from a different deep-space asteroid named Bennu. That vehicle is NASA’s OSIRIS-REx, which launched in 2016. It will arrive at Bennu later this year and eventually try to grab up to 2 kilograms of dirt from one spot on the asteroid’s surface, before returning to Earth. So if all goes well, two different spacecraft from two different countries may bring back asteroid material for scientists to study.<doc-sep>The Japanese space agency has released stunning new pictures taken by a rover standing on top an asteroid. The images, sent down from the surface of the asteroid Ryugu, show the rock in amazing and eerie detail. They were sent back over a distance of around 180 million miles. They come after the space agency successfully landed two rovers on the asteroid, dropping them from a spacecraft floating just above the surface. (Jaxa (Jaxa) The rovers dropped down onto the asteroid by the Hayabusa-2 spacecraft are the first mobile exploration robots ever to land on an asteroid's surface. The images they are sending back are the first time that anything has ever autonomously moved and taken pictures themselves on asteroid, too. One of the pictures includes the shadow of the antenna and pin of the rover itself.​ The pin – which is the long line that can be seen sticking out of the rover – helps increase friction when they engage in the hops that they use to jump around the surface, among other purposes. (Jaxa (Jaxa) Jaxa, the Japanese space agency, says that both of the rovers are "in good condition and are transmitting images and data". The pictures they are sending back have confirmed that they are moving themselves around the asteroid's surface. The rovers will spend their time exploring the planet's surface by being joined by yet another visitor, called Mascot, built by scientists in Germany and France, that will further explore the surface. The new pictures are the second batch to be sent down by the Hayabusa-2 spacecraft. The first were taken as the two rovers tumbled to the surface, and show their whirling motion as they fall.<doc-sep>Japan Aerospace Exploration Agency When it comes to space travel, human beings are just getting started. Robots on the other hand are way ahead. We have the Curiosity Rover doing its thing on Mars, the Parker Solar Probe is en route to the sun. And now JAXA, the Japanese Space Agency, has landed two rovers on a goddamn asteroid. Best of all: They've sent back photographs. We are sorry we have kept you waiting! MINERVA-II1 consists of two rovers, 1a & 1b. Both rovers are confirmed to have landed on the surface of Ryugu. They are in good condition and have transmitted photos & data. We also confirmed they are moving on the surface. #asteroidlanding — HAYABUSA2@JAXA (@haya2e_jaxa) September 22, 2018 The MINERVA rovers were launched from Japan's Hayabusa 2 probe, which has been orbiting an asteroid called Ryuga for a few months now. The probe is on an asteroid sample-return mission, and is planning to survey the asteroid and return to Earth in December 2020. This is a picture from MINERVA-II1. The color photo was captured by Rover-1A on September 21 around 13:08 JST, immediately after separation from the spacecraft. Hayabusa2 is top and Ryugu's surface is below. The image is blurred because the rover is spinning. #asteroidlanding pic.twitter.com/CeeI5ZjgmM — HAYABUSA2@JAXA (@haya2e_jaxa) September 22, 2018 Two MINERVA rovers were deployed on Sept. 21 and both have successfully landed. The first shot sent back can be seen above. It's a little blurry -- mainly because the rover was spinning when it took the shot. Photo taken by Rover-1B on Sept 21 at ~13:07 JST. It was captured just after separation from the spacecraft. Ryugu's surface is in the lower right. The misty top left region is due to the reflection of sunlight. 1B seems to rotate slowly after separation, minimising image blur. pic.twitter.com/P71gsC9VNI — HAYABUSA2@JAXA (@haya2e_jaxa) September 22, 2018 The above image is much clearer. Yep, that's the asteroid itself in the bottom right corner of the photo. This dynamic photo was captured by Rover-1A on September 22 at around 11:44 JST. It was taken on Ryugu's surface during a hop. The left-half is the surface of Ryugu, while the white region on the right is due to sunlight.

Two robotic explorers sent by the Japanese space agency have landed on an asteroid in a world first. The two small rovers are on a mission that could provide clues to the origin of the solar system. The Japan Space Exploration Agency said the two Minerva-II-1 rovers were lowered from the unmanned spacecraft Hayabusa2 to the asteroid Ryugu. The spacecraft arrived near the asteroid, about 170 million miles from Earth, in June. (Image: JAXA/Twitter) (Image: JAXA/Twitter) Confirmation of the robots' safe touchdown was confirmed on Saturday with the agency saying: "Both rovers are in good condition." JAXA proudly tweeted pictures from the rovers, which reached Earth via the spaceship Hayabusa-2. Hayabusa approached as close as 180 feet to the asteroid to lower the rovers, waited for a minute and then rose back to its waiting position about 12 miles above the surface. Jaxa said the release went successfully. (Image: DLR) (Image: JAXA/Twitter) The solar-powered rovers' voltage plunged as night fell on Ryugu, a sign that they are on the asteroid, said Hayabusa project team spokesman Takashi Kubota. The two rovers, each about the size of a cookie can, are to capture images of the asteroid and measure surface temperatures before a larger rover and a lander are released later. While the European Space Agency had previously landed probes on an icy comet, this is the first spacecraft to place robot rovers on the surface of an asteroid. (Image: JAXA/Twitter) The rovers move by "hopping" because the extremely weak gravity on the asteroid makes rolling difficult. They can continue jumping as long as their solar panels and power last, Jaxa said. Hayabusa2 is also scheduled to attempt three brief touch-and-go landings on the asteroid to collect samples in hopes of providing clues to the origin of the solar system and life on Earth. Since it arrived at Ryugu, scientists have been looking for suitable landing sites on the uneven surface, and its first attempt is expected in October. (Image: JAXA/Twitter) The spacecraft is set to release a German-French lander called Mascot carrying four observation devices in early October and a bigger rover called Minerva-II-2 next year. Hayabusa2, launched in December 2014, is due to return to Earth in late 2020.
