NASA’s next Mars rover is due to launch in July or August 2020, and the number of potential landing sites has now been narrowed down by scientists to eight locations. Out of an initial list of 21 targets, eight sites have been chosen as candidate landing sites for the Mars 2020 Rover. Due to land on Mars in February 2021, the rover will search for rocks which could hold possible evidence of past life on the planet.
Near-Earth asteroids, also known as Near Earth Objects (NEOs), are some of the best studied space rocks in the Solar System, primarily due to the fact that they approach the orbit of Earth, making them potentially dangerous to our home planet. Now, a new study has provided evidence that at least some of them, including dark ones which are more difficult to see, originate from the oddball Euphrosyne family of dark asteroids which are at the outer edge of the main asteroid belt between Mars and Jupiter, but have highly inclined orbits well above the plane or “equator” of the Solar System.
In what may be a significant step toward the seemingly far-off goal of sending a rover to the surface of Venus, NASA has awarded two grants totalling $245,000 to a semiconductor technology firm to design complex integrated circuits which could withstand the extremely harsh environment on this neighboring world.
The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which were little known or even unheard of just a decade ago. Among the most remarkable and tantalizing discoveries are the “ocean moons” such as Europa and Enceladus, which have oceans or seas of liquid water beneath their icy surfaces. Other moons like Titan, Ganymede, and Callisto may also have them, and even some asteroids. Titan also has seas and lakes of liquid methane/ethane on its surface. With all that water, these small worlds have become a primary focus in the search for possible life elsewhere in the Solar System. Now, a new NASA budget proposal wants to take that a step further and fund new missions to these watery moons.
With so much attention now on the rovers and spacecraft at Mars, Saturn, Ceres, comet 67P/Churyumov-Gerasimenko, and, soon, Pluto, it may seem like Earth’s closest planetary neighbor Venus has been forgotten again. But no, Venus is still very much on the minds of researchers who are busy developing a concept airplane which could cruise for years in the hellish planet’s atmosphere.
The search for, and discovery of, exoplanets orbiting other stars has become a full-fledged endeavour in recent years, with thousands found so far and more being discovered practically every week. Now, NASA wants to take it a big step further by establishing a coalition of research groups and disciplines tasked specifically with this purpose.
In its continuing progress towards returning American astronauts to space, NASA has announced a new $23.3 million contract for the design of advanced boosters for the Space Launch System (SLS). The SLS heavy-lift rocket will be used to launch the manned Orion Multi-Purpose Crew Vehicle spacecraft into space, taking astronauts back to the Moon and even beyond.
The prospect of when, or even if, NASA astronauts will return to the Moon has been a subject of much debate in recent years. Some experts see it as a necessary stepping stone before future Mars missions. Others see it as a case of “been there, done that.”
All these worlds are yours except Europa
Attempt no landing there
Use them together use them in peace
Despite that famous cryptic warning in the film 2010: The Year We Make Contact, NASA is planning for a possible attempted landing on Jupiter’s moon Europa. This is a mission that many people have been hoping for, since Europa is believed to have a liquid water ocean beneath the icy surface (as well as lakes within the surface crust itself), making it a prime location in the search for life elsewhere in the solar system. Two landers are being proposed which would launch in 2020 and land about six years later…

If you are a Star Trek fan, you will of course be familiar with “tractor beams,” those cool-looking laser beams that can grab an object in space and it pull backwards toward the source of the beam (including trapping spacecraft as evil aliens would often do). They are another long-running staple of science fiction that is now closer to science reality. NASA is now working on developing just such technology, which would help primarily in obtaining material samples in real-life space missions, such as on Mars or an asteroid or comet…
