In December of 2014, the Japanese Aerospace Exploration Agency (JAXA) launched the Hayabusa2 mission. As the second spacecraft to bear this name, Hayabusa2 was deployed by JAXA to conduct a sample-return mission with an asteroid. By studying samples of the near-Earth asteroid 162173 Ryugu, scientists hope to shed new light on the history of the early Solar System

The spacecraft arrived in orbit around Ryugu in July of 2018, where it will spend a total of a year and a half surveying the asteroid before returning to Earth. On September 23rd, the satellite deployed its onboard MINERVA-II rovers onto the surface of Ryugu. According to the latest updates from JAXA, both rovers are in good condition and have recently sent back photographs and a video of the asteroid’s surface.

NASA Tests a Tiny Satellite to Track Extreme Weather and Storms

Weather tracking is difficult work, and has historically relied on satellites that are large and cost millions of dollars to launch into space. And with the threat of climate change making things like tropical storms, tornadoes and other weather events more violent around the world today, people are increasingly reliant on early warnings and real-time monitoring.

However, NASA is looking to change that by deploying a new breed of weather satellite that takes advantage of recent advances in miniaturization. This class of satellite is known as the RainCube (Radar in CubeSat), which uses experimental technology to see storms by detecting rain and snow using very small and sophisticated instruments.

The “Death Comet” Will Pass By Earth Just After Halloween

On October 31st, 2015, NASA tracked a strange-looking comet as it made a close flyby of Earth. This asteroid, known as 2015 TB145, was monitored by the multiple observatories and radar installation of the agency’s Deep Space Network. Because of the timing and the skull-like appearance of this asteroid, scientists nicknamed it the “Death Comet”.

Naturally, there was no reason to worry, as the asteroid posed no threat and passed within about 498,900 km (310,000 mi) of Earth. But the timing and the appearance of the comet were nothing if not chilling. And coincidentally enough, the “Death Comet” (aka. “The Great Pumpkin Comet”), will be passing Earth for the second time, this time shortly after Halloween.

NASA Report Outlines How it Will Go Back to the Moon, to Mars, and Beyond in a Sustainable Way

In the coming decades, NASA intends to mount some bold missions to space. In addition to some key operations to Low Earth Orbit (LEO), NASA intends to conduct the first crewed missions beyond Earth in over 40 years. These include sending astronauts back to the Moon and eventually mounting a crewed mission to Mars.

To this end, NASA recently submitted a plan to Congress that calls for human and robotic exploration missions to expand the frontiers of humanity’s knowledge of Earth, the Moon, Mars, and the Solar System. Known as the National Space Exploration Campaign, this roadmap outlines a sustainable plan for the future of space exploration.

Titan First-Ever Detected Dust Storms Prove the Moon is More Earth-like than Ever

Ever since the Cassini orbiter entered the Saturn system in July of 2004, scientists and the general public have been treated to a steady stream of data about this ringed giant and its many fascinating moons. In particular, a great deal of attention was focused on Saturn’s largest moon Titan, which has many surprising Earth-like characteristics.

These include its nitrogen-rich atmosphere, the presence of liquid bodies on its surface, a dynamic climate, organic molecules, and active prebiotic chemistry. And in the latest revelation to come from the Cassini orbiter, it appears that Titan also experiences periodic dust storms. This puts it in a class that has so far been reserved for only Earth and Mars.

NASA Spots Opportunity as the Dust Storm Clears. Still No Word From Her Though

A new image produced by the High-Resolution Imaging Science Experiment (HiRISE) aboard NASA’s Mars Reconnaissance Orbiter (MRO) has located the Opportunity rover on Mars. As expected, the rover was spotted on the  slopes of the Perseverance Valley, where it went into hibernation mode about 100 days ago when the planet-covering dust storm darkened skies above the region.

Optical Rocket Boosts Electrons to Nearly the Speed of Light

A team of researchers from the University of Nebraska–Lincoln recently conducted an experiment where they were able to accelerate plasma electrons to close to the speed of light. This “optical rocket”, which pushed electrons at a force a trillion-trillion times greater than that generated by a conventional rocket, could have serious implications for everything from space travel to computing and nanotechnology.

Musk Gives an Update on When a Mars Colony Could be Built

Elon Musk is well-known for his ability to create a media sensation. Scarcely a week goes by that the founder of SpaceX and Tesla doesn’t have an announcement or update to make – often via his social media outlet of choice, twitter. And as a major figure in the NewSpace industry, anything he says is guaranteed to elicit reactions (both critical and hopeful) from the space community and general public.

Just last week (on Monday, Sept. 17th), he revealed new information about the Big Falcon Rocket (BFR)  and who its first passenger would be when it conducts its first lunar mission (which is planned for 2023). And on Friday (Sept. 21st), Musk shared some updated plans on when a SpaceX Martian colony could be established. According to the tweet he posted, his company could build a base on Mars (Mars Base Alpha) as early as 2028.

Astronomers are Tracking the Interstellar Asteroid ‘Oumuamua to its Home System

On October 19th, 2017, the Panoramic Survey Telescope and Rapid Response System-1 (Pan-STARRS-1) in Hawaii announced the first-ever detection of an interstellar asteroid – I/2017 U1 (aka. ‘Oumuamua). Since that time, multiple studies have been conducted to determine the asteroid’s origin, what it encountered in interstellar space, its true nature (is it a comet or an asteroid?), and whether or not it is an alien spacecraft (it’s not).

In all this time, the question of  ‘Oumuamua’s origin has remained unanswered. Beyond theorizing that it came from the direction of the Lyra Constellation, possibly from the Vega system, there have been no definitive answers. Luckily, an international team led by researchers from the Max Planck Institute for Astronomy (MPIA) have tracked ‘Oumuamua and narrowed down its point of origin to four possible star systems.

On August 12th, 2018, NASA launched the first spacecraft that will ever “touch” the face of the Sun. This was none other than the Parker Solar Probe, a mission that will revolutionize our understanding of the Sun, solar wind, and “space weather” events like solar flares. Whereas previous missions have observed the Sun, the Parker Solar Probe will provide the closest observations in history by entering the Sun’s atmosphere (aka. the corona).

And now, just over a month into the its mission, the Parker Solar Probe has captured and returned its first-light data. This data, which consisted of images of the Milky Way and Jupiter, was collected by the probe’s four instrument suites. While the images were not aimed at the Sun, the probe’s primary focus of study, they successfully demonstrated that the Parker probe’s instruments are in good working order.
